    [015] The following describes an embodiment of the present invention with reference to the drawings.
    [016] FIG. 1 is a block diagram of a non-contact electrical source system including a vehicle 200 and an electrical source device 100, which includes a non-contact electrical source device according to the embodiment of the present invention. A unit on the vehicle side of the non-contact electricity source device of the embodiment is mounted on an electric vehicle, but can be mounted on a hybrid electric vehicle or the like.
    [017] As shown in FIG. 1, the non-contact electricity source system of this embodiment includes the vehicle 200 and the electricity source device 100, where the vehicle 200 includes the vehicle-side unit, and the electricity source device 100 is a vehicle-side unit. ground. In this system, power is supplied non-contact from the electricity source device 100 that is provided in an electricity source station or the like, to charge a battery 28 that is provided in the vehicle 200.
    [018] The electricity source device 100 includes a power control section 11, a power supply coil 12, a signal receiving section 13, a wireless communication section 14, and a control section 15. Electricity source device 100 is a ground-side unit that is provided in a parking space where vehicle 200 is parked, and supplies power by contactless electricity supply between coils when vehicle 200 is parked in a specific parking position.
    [019] The power control section 11 is a circuit for performing a conversion of an alternating current power sent from an alternating current power source 300 to a high frequency alternating current power, and sending the same to the power supply coil 12. The power control section 11 includes a rectifying section 111, a PFC (Power Factor Correction) circuit 112, an inverter 113, and a sensor 114. The rectifying section 111 is a circuit which is electrically connected with the alternating current power source 300, and rectifies the alternating current power emitted from the alternating current power source 300. The PFC 112 circuit is a circuit for improving the power factor by formatting the waveform emitted from the rectifying section 111, and is connected between the rectifying section 111 and the inverter 113. The inverter 113 is a power conversion circuit which includes a final filtration capacitor, and a switching element such as an IGBT. The inverter 113 converts a direct current power to a high frequency alternating current power based on a switching control signal from the control section 15, and supplies the same to the power supply coil 12. The sensor 114 is connected between the PFC 112 circuit and the 113 inverter, and senses the electric current and voltage. Power supply coil 12 is a coil for supplying non-contact power to a power supply coil 22 that is provided in vehicle 200. Power supply coil 12 is provided in a parking space where the power supply device Contactless electricity of this embodiment is provided.
    [020] When the vehicle 200 is parked in a specified parking position, the power supply coil 12 is positioned below the power supply coil 22 at some distance from the power supply coil 22. The power supply coil 12 is a circular coil that is parallel to the surface of the parking space.
    [021] The signal receiving section 13 is a sensor composed of signal receiving antennas, and is provided in the electricity source device 100 on the ground side, and receives an electromagnetic wave, which is sent from the section sending signal 23 by measuring the magnetic field around the signal receiving antennas. Each signal receiving antenna is a magnetic field antenna or something similar. The frequency of the electromagnetic wave sent and received between the signal receiving section 13 and the signal sending section 23 is set lower than the communication frequency between the wireless communication section 14 and an unused communication section of wires 24 which is described below. The frequency of the electromagnetic wave belongs to or is close to a frequency band used by a vehicle peripheral device such as a smart key. The communication between the signal receiving section 13 and the signal sending section 23 is implemented by a communication system suitable for short distance communication, compared to the communication between the wireless communication section 12 and the section. of wireless communication 24 which is described below.
    [022] The wireless communication section 14 performs bidirectional communication with the wireless communication section 24 which is provided in the vehicle 200. The wireless communication section 14 is provided in the electricity source device 100 on the ground side. The frequency of communication between the wireless communication section 14 and the wireless communication section 24 is set higher than the frequency used for communication between the signal receiving section 13 and the signal sending section 23, and also greater than the frequency used by a vehicle peripheral device such as a smart key. Consequently, the vehicle peripheral device is unlikely to be subject to interference due to the communication between the wireless communication section 14 and the wireless communication section 24. The communication between the wireless communication section 14 and the wireless communication section 24 is implemented by a wireless LAN system or the like. The communication between the wireless communication section 14 and the wireless communication section 24 is thus implemented by a communication system suitable for long-distance communication, compared to the communication between the signal receiving section 13 and the signal sending section 23.
    [023] The control section 15 is a section for controlling as a whole the electricity source device 100. The control section 15 includes a distance measuring section 151, a position sensing section 152, and a distance measurement section. foreign object detection 153, and controls the power control section 11, the power supply coil 12, the signal receiving section 13, and the wireless communication section 14. The control section 15 sends to vehicle 200 a control signal indicating a start of power supply from electricity source device 100, and receives from vehicle 200 a control signal indicating a request to receive power from the electricity source device 100, by communicating between the wireless communication section 14 and the wireless communication section 24. The control section 15 performs switching control of the inverter 113, and thereby controls the power fed from the coil. in the power supply 12, depending on a current perceived by the sensor 114.
    [024] The vehicle 200 includes the energy receiving coil 22, the signal sending section 23, the wireless communication section 24, a load control section 25, a rectifying section 26, a relay 27, a battery 28, an inverter 29, and an electric motor 30. The power receiving coil 22 is provided on the underside (chassis) or the like of the vehicle 200, and between the rear wheels of the vehicle 200. When vehicle 200 is parked in the specified parking position, energy receiving coil 22 is positioned above power supply coil 12 at some distance from power supply coil 12. Energy receiving coil 22 is a circular coil. which is parallel to the surface of the parking space.
    [025] The signal sending section 23 is a sensor composed of a signal sending antenna, and it is provided in the vehicle 200, and sends an electromagnetic wave to the signal receiving section 12. The signal sending antenna is a magnetic field antenna or something like that. The wireless communication section 24 performs bidirectional communication with the wireless communication section 14 provided in the electricity source device 100. The wireless communication section 24 is provided in the vehicle 200.
    [026] The rectifying section 26 is connected with the energy receiving coil 22, and is composed of a rectifying circuit for rectifying to a direct current an alternating current received in the energy receiving coil 22. The relay section 27 includes a relay switch that is turned on and off under control of the load control section 25. When the relay switch is turned off, the relay section 27 separates a higher power system including battery 28 from a lower power system including the power receiving coil 22 and the rectifying section 26 which constitute a circuit section for charging.
    [027] The battery 28 is composed of several secondary cells connected with each other, and serves as a power supply for the vehicle 200. The inverter 29 is a control circuit such as a PWM control circuit including a switching element such as as an IGBT. The inverter 29 converts to an alternating current energy direct current energy emitted from the battery 28, and supplies the same to the electric motor 30, depending on a switching control signal. Electric motor 30 is a three-phase alternating current motor or the like, and serves as a motive source to drive vehicle 200.
    [028] The charge control section 25 is a controller for controlling the charge of the battery 28. The charge control section 25 controls the signal sending section 23, and the wireless communication section 24. The section The load control terminal 25 sends to the control section 15 a signal indicating a start of load, by the communication between the wireless communication section 24 and the wireless communication section 14. The load control section 25 is connected via a CAN communication network with a controller not shown which controls the whole of the vehicle 200. This controller manages the switching control of the inverter 29 and the state of charge (SOC) of the battery 28. The charge control section 25 sends to control section 15 a signal indicating a completion of charge, depending on the SOC of battery 28, when full charge is reached.
    [029] In the non-contact electricity source device of this embodiment, the power supply and energy reception of high frequency energy is implemented by electromagnetic induction between the energy supply coil 12 and the energy reception coil 22 which they are out of touch with each other. In other words, when an electrical voltage is applied to the power supply coil 12, then magnetic coupling occurs between the power supply coil 12 and the power receiving coil 22, so that power is supplied from the power supply coil 12 to power take-up coil 22.
    [030] The following describes the configuration of the signal receiving section 13 and the signal sending section 23 with reference to FIG. 2. FIG. 2 is a perspective view of the power supply coil 12, the signal receiving section 13, the power receiving coil 22, and the signal sending section 23, which are included in the power source device without contact of this realization.
    [031] The signal receiving section 13 is composed of four signal receiving antennas 13a, 13b, 13c, 13d which are provided on the periphery of the power supply coil 12. The signal receiving antennas 13a, 13b, 13c 13d are arranged in symmetry with respect to the center of the power supply coil 12. The signal sending section 23 is composed of a single signal sending antenna which is provided at the center point of the signal sending section 23.
    [032] The positions of the power supply coil 12 and the signal receiving section 13 are unchanged, because the power supply coil 12 and the signal receiving section 13 are provided in the electricity source device 100 on the side from soil. On the other hand, the positions of the power receiving coil 22 and the signal sending section 23 are changed with respect to the positions of the power supply coil 12 and the signal receiving section 13, depending on the parking position of the vehicle. 200 with respect to the prescribed parking space, because the power receiving coil 22 and the signal sending section 23 are provided in the vehicle 200.
    [033] The signal receiving section 13 and the signal sending section 23 are arranged so that the distance between the position of each signal receiving antenna 13a, 13b, 13c, 13d and the position of the signal sending section signal 23 is the same as each other when the vehicle 200 is parked in the prescribed parking space so that the center point of the energy receiving coil 22 and the center point of the energy supply coil 12 are identical to each other in the direction of planes of the coils between the power-taking coil 22 and the power-supply coil 12, i.e. in the direction of the surfaces of the power-taking coil 22 and the power-supply coil 12.
    [034] Each signal receiving antenna 13a, 13b, 13c, 13d receives a signal sent from the antenna of the signal sending section 23. When the center point of the energy receiving coil 22 is the center point of the power coil. power supply 12 are identical in the direction of the surfaces of power receiving coil 22 and power supply coil 12, the power of the signal received by each signal receiving antenna 13a, 13b, 13c, 13d is equal to each other. . On the other hand, when the center point of the power receiving coil 22 and the center point of the power supply coil 12 are offset from each other, the power of the signal received by each signal receiving antenna 13a, 13b, 13c, 13d is not the same as each other. Consequently, in this embodiment, the position deviation of the coil is detected by sensing the position relationship between the power supply coil 12 and the power receiving coil 22 based on the output values of the various sensors configured in the section of signal reception 13 and in the signal sending section 23 as described below.
    [035] The following describes a control performed by control section 15 and load control section 25 with reference to FIGS. 1 and 2.
    [036] Control section 15 performs a system check as a power-on control, determining whether or not power supply device 100 systems operate normally. Similarly, the load control section 25 performs a system check like a start control, determining whether or not a vehicle load system 200 operates normally. When the result of the system check indicates that a system abnormality is present in vehicle 200, control section 15 informs a user. When the result of the system check indicates that a system abnormality is present in the electricity supply device 100, the control section 15 notifies a center or the like that is managing the electricity supply device 100. On the other hand, when the system check is normal, the control section 15 initializes the wireless communication section 14, and thereby establishes a condition where a signal can be received. For example, the system check against the electricity source device 100 is performed at intervals of a specified period, whereas the system check against the vehicle 200 is performed when a master switch is turned on where the master switch serves. to drive the vehicle 200.
    [037] Control section 15 and load control section 25 control wireless communication section 14 and wireless communication section 24, respectively, by the following remote communication control. First, the load control section 25 obtains information about the current position of the vehicle 200 by a GPS function provided in the vehicle 200, and determines whether or not the current position of the vehicle 200 is within a predetermined load point. The charge point is set individually for the electricity source device 100, and is, for example, a region that is displayed on a map as a circle having a center at the position of the electricity source device 100. The condition that the vehicle 200 is within the charge point means that the charge of the battery 28 will be implemented by the electricity source device 100 corresponding to the charge point.
    [038] When the current position of the vehicle 200 is within the load point, the load control section 25 initializes the wireless communication section 24, and thereby allows communication between the wireless communication section. 14 and the wireless communication section 24. When communication is allowed between the wireless communication section 14 and the wireless communication section 24, then the load control section 25 sends from the wireless communication section 24 to the wireless communication section 14 a signal for establishing a data link. Then, the control section 15 sends back from the wireless communication section 14 to the wireless communication section 24 a signal indicating that the control section 15 has received the signal. This process establishes the data link between the wireless communication section 14 and the wireless communication section 24.
    [039] In addition, the load control section 25 sends a vehicle ID 200 to the control section 15 via communication between the wireless communication section 14 and the wireless communication section 24. A control section 15 performs ID authentication by determining whether or not the ID sent from vehicle 200 matches one of the registered IDs. In this contactless electricity source system, chargeable vehicles 200 are proactively registered by ID on each electricity source device 100. As a result, vehicle 200 can receive electricity when ID authentication indicates the vehicle ID 200 matches a registered ID.
    [040] When the data link is established and authentication is terminated, then the load control section 25 sends a signal from the wireless communication section 24 to the wireless communication section 14 at intervals predetermined, while the vehicle 200 is approaching the electricity source device 100 corresponding to the charge point. The control section 15 measures the distance between the vehicle 200 and the electricity source device 100 by the distance measuring section 151. The wireless communication section 14 receives the signal sent periodically from the unused communication section of wires 24. Distance measuring section 151 measures the distance between the vehicle 200 and the electricity source device 100 based on the electric field strength of the received signal.
    [041] The control section 15 receives a threshold value that is set as a predetermined vehicle approach threshold value to indicate a condition where the vehicle 200 has approached the electricity source device 100 so that the distance between the coil of the power supply coil 12 and the power taking coil 22 in the direction of the surfaces of the power supply coil 12 and the power taking coil 22 becomes short. In this embodiment, the vehicle approach threshold value is prescribed in terms of signal strength, because the received signal strength correlates with the distance between the vehicle 200 and the electricity source device 100.
    [042] Control section 15 compares the electric field strength of the received signal with the vehicle approach threshold value, and determines whether or not the distance between vehicle 200 and electricity source device 100 is shorter than a prescribed value. When the distance between the vehicle 200 and the electricity source device 100 is shorter than the prescribed value, then the control section 15 initializes the signal receiving section 13, and sends a control signal from the wireless communication 14 to wireless communication section 24. Upon receiving the control signal, the load control section 25 initializes the signal sending section 23. Consequently, the signal receiving section 13 starts before signal sending section 23.
    [043] Thus, in this embodiment, the sending and receiving of signal between the signal receiving section 13 and the signal sending section 23 is not constantly performed, but the signal receiving section 13 and the sending section signals 23 are initialized to perform signal sending and receiving, when the vehicle 200 has approached the electricity source device 100. The signal receiving section 13 and the signal sending section 23 are controlled to be initialized and emitting radio waves when the signal receiving section 13 and the signal sending section 23 approach each other so that the power supply coil 12 and the power supply coil 22 overlap. This serves to suppress radio wave leakage influences from the signal receiving section 12 and the signal sending section 23 on other surrounding devices.
    [044] After completing remote communication control, control section 15 and load control section 25 perform position sensing control as follows. When recognizing that the vehicle 200 is stationary, the load control section 25 sends a signal from the signal sending antenna of the signal sending section 23 to the signal receiving antennas 13a, 13b, 13c, 13d of the section. signal receiving antenna 13. The control section 15 measures the output value of the signal received by each receiving antenna 13a, 13b, 13c, 13d, and first determines whether the signal receiving antennas 13a, 13b, 13c, 13d and the signal sending antenna are normal or not. The control section 15 receives an upper limit value and a lower limit value which are set as position determination limit values to determine antenna abnormality. When all the output values of the signal receiving antennas 13a, 13b, 13c, 13d are in the range from the lower limit value to the upper limit value, then the control section 15 determines that the signal receiving section 13 and the signal sending section 23 are operating normally. On the other hand, when the output value of the signal receiving antenna 13a, 13b, 13c, 13d is higher than the upper limit value or less than the lower limit value, then the control section 15 determines that by least one of the signal receiving section 13 and the signal sending section 23 is faulty. When determining that the signal receiving section 13 or signal sending section 23 is at fault, then the control section 15 sends a signal indicating the abnormality through the wireless communication section 14 and the wireless communication 24 to the load control section 25. Then, the load control section 25 notifies the user about the abnormality of the signal receiving section 13 or the signal sending section 23. On the other hand, the control section 15 notifies the center, which is managing the electricity source device 100, of the abnormality of the signal receiving section 13 or the signal sending section 23.
    [045] When the signal receiving section 13 and the signal sending section 23 are normal, the control section 15 detects a position deviation between the coils, namely, detects an overlap state between the power coil of energy 12 and the energy receiving coil, by the position sensing section 152, and detects a foreign object present between the coils by the foreign object sensing section 153, as follows. The following describes the control of detecting a position deviation between the coils, and the control of detecting a foreign object between the coils with reference to FIGS. 3 through 5. FIG. 3 shows a condition where the power supply coil 12 and the power take coil 22 face each other without shifting position, where FIG. 3A is a plan view, and FIGS. 3B and 3C are perspective views. FIG. 4 shows a condition where the power supply coil 12 and the power supply coil 22 face each other with a positional deviation, where FIG. 4A is a plan view, and FIGS. 4B and 4C are perspective views. FIG. 5 presents a condition where a foreign object 40 is present in the power supply coil 12 with respect to FIG. 4, where FIG. 5A is a plan view, and FIGS. 5B and 5C are perspective views. The X axis and the Y axis represent the direction of the surfaces of the power supply coil 12 and the energy take coil 22, and the axis Z represents the height direction.
    [046] When the center point of the power supply coil 12 and the center point of the power take-up coil 22 are identical to each other in the direction of the surfaces of the power supply coil 12 and the power take-up coil 22 as shown in FIG. 3, the distance from the signal sending antenna of the signal sending section 23 to each signal receiving antenna 13a, 13b, 13c, 13d of the signal receiving section 13 is equal to each other so that the value output of the signal received by the signal receiving antenna 13a, 13b, 13c, 13d is equal to each other. The output value of each signal receiving antenna 13a, 13b, 13c, 13d for the situation shown in FIG. 3 is represented by “S”.
    [047] On the other hand, when the energy receiving coil 22 is offset in the direction of the geometric axis X with respect to the energy supply coil 12 as shown in FIG. 4, the distance from the signal sending section 23 to the signal receiving antenna 13a, 13d becomes shorter than the distance from the signal sending section 23 to the signal receiving antenna 13b, 13c . The distance from the signal sending section 23 to the signal receiving antenna 13a, 13d is shorter than the distance from the signal sending section 23 to the signal receiving antenna 13a, 13b, 13c, 13d under the condition shown in FIG. 3, so that the output value of the signal receiving antenna 13a, 13d is greater than the output value S, and equal to S + 30, for example. On the other hand, the distance from the signal sending section 23 to the signal receiving antenna 13b, 13c is longer than the distance from the signal sending section 23 to the signal receiving antenna 13a, 13b, 13c, 13d under the condition shown in FIG. 3, so that the output value of the signal receiving antenna 13b, 13c is less than the output value S, and equal to S - 30, for example.
    [048] Accordingly, the position sensing section 152 perceives the relative position of the power receiving coil 22 with respect to the power supply coil 12 by comparing the output values of the signal receiving antennas 13a, 13b, 13c , 13d with the output value S as a reference, and calculate the offset of the output value of each signal receiving antenna 13a, 13b, 13c, 13d.
    [049] The following describes a control process for foreign object detection, which is performed by the foreign object detection section 153. As shown in FIG. 5, when a foreign object 40 is present near the signal receiving antenna 13a under a similar positional relationship of the coils as shown in FIG. 4, the signal sent from the signal sending section 23 to the signal receiving antenna 13a is interrupted by the foreign object 40 so that the output value of the signal receiving antenna 13a becomes less than the value of output of the signal receiving antenna 13a under the condition shown in FIG. 4, (S + 30), and equal to S - 600, for example. On the other hand, the output values of the receiving antennas 13b, 13c, 13d are equal to S-30, S-30, S+30, respectively, as in the case of FIG. 4.
    [050] The foreign object detection section 153 obtains the absolute values of differences between the output values of the signal receiving antennas 13a, 13b, 13c, 13d, and compares the absolute value of each difference with a threshold value, and when the difference is greater than the threshold value it determines that a foreign object is present between the coils. The threshold value is a predetermined foreign object identification threshold used to determine whether or not a foreign object is present. In this embodiment, the foreign object identification threshold is set to 60.
    [051] In the examples presented in FIGS. 4 and 5, the output values of the signal receiving antennas 13a, 13b, 13c, 13d are represented by a, b, c, and d, respectively. In the example shown in FIG. 4, the absolute value of each difference is calculated by the foreign object detection section 153 as said below. |b-a| = 60, |c-a| = 60, |d-a| = 0 |c-b| = 0, |d-b| = 60, and |d-c| = 60
    [052] The foreign object detection section 153 compares the absolute value of each difference with the foreign object identification threshold value, and determines that each difference is less than or equal to the foreign object identification threshold value (=60), and thereby determines that no foreign objects are present between the energy supply coil 12 and the energy reception coil 22.
    [053] On the other hand, in the example shown in FIG. 5, the absolute value of each difference is calculated by the foreign object detection section 153 as said below. |b-a| = 570, |c-a| = 570, |d-a| = 630, |c-b| = 0, |d-b| = 60, and |d-c| = 60
    [054] The foreign object detection section 153 compares the absolute of each difference with the foreign object identification threshold, and determines that the differences |b-a|, |c-a|, and |d-a| are greater than the foreign object identification threshold, and thus determines that a foreign object is present. Since the output value a is common among the differences greater than the foreign object identification threshold value, the foreign object detection section 153 can determine that a foreign object is present near the signal receiving antenna 13a. In this way, the foreign object detection section 153 determines whether or not a foreign object is present between the power supply coil 12 and the energy receiving coil 22, and also determines the location of the foreign object.
    [055] The control section 15 sends to the vehicle 200 via communication between the wireless communication section 14 and the wireless communication section 24 the relative position of the energy receiving coil 22 with respect to the coil of power supply 12 which is detected by the position sensing section 152. In addition, the control section 15 sends a signal to the vehicle 200 via communication between the wireless communication section 14 and the wireless communication section. Use wire 24 when a foreign object is detected by the tin object detection section 153.
    [056] After completing position sensing control, control section 15 and load control section 25 perform the next load control. The load control section 25 calculates a load period based on information about the position deviation of the coil that is received by the wireless communication section 24. The energy 12 for the power receiving coil 22 depends on the coupling coefficient between the power supply coil 12 and the power receiving coil 22, and the coupling coefficient depends on the positional relationship between the power supply coil 12 and the energy receiving coil 22. Accordingly, the load control section 25 can calculate the energy received by the energy receiving coil 22, based on the energy sent from the energy supply coil 12, if recognizing the relationship. of position between the power supply coil 12 and the power take coil 22. In addition, the load control section 25 can calculate the load period based on the power. the load corresponding to the power received based on the position deviation of the coil, and the SOC of the battery 28 managed by the controller not shown. When a user decides to allow charging operation during the charging period calculated by the charge control section 25, the charge control section 25 then sends to the electricity source device 100 via communication between the unused communication section. wires 14 and wireless communication section 24 a signal indicating a start of charging, in response to user operation. In response to the signal, the control section 15 starts charging operation. On the other hand, when the user decides not to allow the charging operation during the charging period calculated by the charge control section 25, the user redoes the parking in order to reduce the position deviation of the coil, and thus, shortens the charging period. When the battery 28 is fully charged, then the charge control section 25 sends from the wireless communication section 24 to the wireless communication section 14 a control signal indicating a termination of charge, so that the control section 15 stops the load operation based on the control signal.
    [057] When the load control section 25 receives from the wireless communication section 24 a signal indicating the detection of a foreign object, then the load control section 25 notifies the user of the presence of the foreign object. through the driver not shown. User can start loading after removing foreign object based on notification. When detecting a foreign object, the control section 15 does not perform the loading operation.
    [058] The following describes a control process performed by the non-contact electricity source system according to the present embodiment, with reference to FIGS. 6 through 8. FIG. 6 is a flowchart showing a process for controlling the wireless electricity source system in accordance with the present embodiment. FIG. 7 is a flowchart showing a process for controlling a remote communication control shown in FIG. 6. FIG. 8 is a flowchart showing a process for controlling a position sensing control shown in FIG. 6.
    [059] At Step S1, control section 15 and card control section 25 perform a system check as a power-on control. In Step S2, the control section 15 and the load control section 25 perform a remote communication control.
    [060] With respect to the remote communication control in Step S2, the load control section 25 obtains the current position of the vehicle 200 by the GPS function of the controller not shown, in Step S21, as shown in FIG. 6. In Step S22, the charge control section 25 determines whether or not the actual position obtained is within the charge point of the electricity source device 100. When the actual position is not within the charge point, the process of control then returns to Step S21. When the actual position is within the load point, the load control section 25 then initializes the wireless communication section 24 in Step S23.
    [061] In Step S24, the control section 15 and the load control section 25 perform signal sending and receiving between the wireless communication section 14 and the wireless communication section 24 to establish a data link, and determine whether or not a data link has been established. When no data link is established, the control process returns to Step S24 where signal sending and receiving is redone between the wireless communication section 14 and the wireless communication section 24. When a link is established, the load control section 25 sends the vehicle ID 200 to the power source device 100 in Step S25. The control section 15 performs ID authorization by checking IDs contained in the signal received by the wireless communication section 14 against the IDs registered in the electricity source device 100.
    [062] When the authorization of the ID fails, then the process of controlling this realization is terminated. On the other hand, when the ID authorization is successful, the load control section 25 sends signals from the wireless communication section 24 at intervals of a predetermined period to inform that the vehicle 200 is approaching the delivery device. source of electricity 100 in Step S26. The control section 15 measures the distance between the vehicle 200 and the electricity source device 100 by allowing the distance measuring section 151 to measure the electric field strength of the signal received by the wireless communication section 14 Then, in Step S27, the control section 15 determines whether or not the electric field strength of the received signal is greater than the vehicle approach threshold value. When the electric field strength of the received signal is less than or equal to the vehicle approach threshold value, it is determined that the vehicle approach 200 to the electricity source device 100 is insufficient for initializing the signal receiving section 13 and from the signal sending section 23 for detecting coil position deviation, and thereby, the control process returns to Step S26. On the other hand, when the electric field strength of the received signal is greater than the vehicle approach threshold value, it is determined that the vehicle approach 200 to the electricity source device 100 is sufficient, and thus the process control returns to Step S3 so that remote communication control is terminated.
    [063] With respect to the position sense control in Step S3, the control section 15 initializes the signal receiving section 13, and sends from the wireless communication section 14 to the wireless communication section. wires 24 a signal indicating a start of position sensing control at Step S31 as shown in FIG. 8. In Step S32, load control section 25 initializes signal sending section 23, depending on the signal sent in Step S31. At Step S33, the control section 15 measures the output values of the signals that are sent from the signal sending section 23 and received by the signal receiving antennas 13a, 13b, 13c, 13d of the signal receiving section 13 In Step S34, the control section 15 determines whether or not the output value of each received signal is greater than the lower limit of the abnormality check, and less than the upper limit of the abnormality check.
    [064] When the output values of the received signals are greater than the lower limit and less than the upper limit, then the control section 15 calculates differences between the output values of the signals received by the signal receiving antennas 13a , 13b, 13c, 13d, in Step S35. In Step S36, the control section 15 makes the foreign object detection section 153 determine whether or not the absolute value of each output value difference is less than or equal to the foreign object detection threshold value. When the absolute value of each output value difference is less than or equal to the foreign object detection threshold value, the foreign object detection section 153 determines, in Step S37, that no foreign objects are present between the power supply coil. power 12 and power receiving coil 22. In Step S38, control section 15 causes position sensing section 152 to sense the relative position of power receiving coil 22 with respect to power supply coil 12 based on the output values of the signal receiving antennas 13a, 13b, 13c, 13d which are measured in Step S33, and thereby perceive a position deviation of the power receiving coil 22 from the power supply coil 12, and sends a sensing result to vehicle 200, and then control continues to Step S4 so that position sensing control is terminated.
    [065] Referring again to Step S36, when the absolute values of the differences between the output values of the signal receiving antennas 13a, 13b, 13c, 13d are greater than the foreign object detection threshold, the section Foreign object detection 153 determines, in Step S361, that a foreign object is present. Then, in Step S362, the control section 15 sends to the vehicle 200 via the wireless communication section 14 a signal indicating the presence of the foreign object. The load control section 25 notifies the user of the presence of the foreign object, based on the signal received by the wireless communication section 24. When the foreign object is present, the control process of this embodiment is terminated without proceeding to control load in Step S4.
    [066] Referring again to Step S34, when the output values of signal receiving antennas 13a, 13b, 13c, 13d are less than the lower limit or greater than the upper limit, the control section 15 determines that an abnormality is present in signal receiving section 13 or signal sending section 23 in Step S341. Then, in Step S362, the control section 15 sends to the vehicle 200 via the wireless communication section 14 a signal indicating that the abnormality is present in the signal receiving section 13 or in the signal sending section 23. The load control section 25 notifies the user of the presence of the abnormality, based on the signal received by the wireless communication section 24. When the abnormality is present in the signal receiving section 13 or the signal sending section 23, the control process of this embodiment is terminated without proceeding to load control in Step S4.
    [067] Referring again to FIG. 6, in Step S4, the charge control section 25 calculates the charge period based on the information on the coil position deviation sensed by the position sense section 152 and the SOC of the battery 28, and notifies the user of the period of charge. Then, depending on the user's operation, the charge control section 25 sends to the electricity source device 100 a signal indicating a start of charge. When receiving the signal, the control section 15 then initiates the supply of electricity from the power supply coil 12 to the power receiving coil 22. At the start of the load, the control section 15 stops the power receiving section. signal 13, whereas the charge control section 25 stops the signal sending section 23. Then, when the battery 28 is fully charged, the control section stops the electricity supply, and terminates the charge control of this embodiment. .
    [068] As described above, the non-contact electricity source system according to the present embodiment includes the wireless communication section 14 and the wireless communication section 24, and the signal sending section 23 and the signal receiving section 13. The non-contact electricity source system senses the distance between the vehicle 200 and the electricity source device 100 based on the outputs of the wireless communication sections; and initializes the signal sending section 23 and the signal receiving section 13, and perceives the positional relationship between the power supply coil 12 and the power receiving coil 22 based on the output of the signal receiving section 13 , when the distance is shorter than the vehicle approach limit value. This makes it possible to initialize the signal receiving section 13 and the signal sending section 23, and output signals, when the vehicle 200 is positioned on the power supply coil 12, and thereby prevent radio wave leakage due to signals, and suppress radio wave interference with external peripheral devices. Furthermore, the aspect of the present embodiment that the signal receiving section 13 and the signal sending section 23 need not be constantly energized, makes it possible to reduce radio wave leakage from the signal receiving section 13 and the section. sending signal 23, and thereby suppressing influences to external peripheral devices, such as a smart switch system and a tire air pressure monitoring system.
    [069] In the present embodiment, the distance between the vehicle 200 and the electricity source device 100 is perceived based on the electrical field strength of the signal received by the wireless communication section 14. This makes it possible to impede signals from the peripheral devices described above from suffering interference from the signal used to perceive the distance between the vehicle 200 and the electricity source device 100.
    [070] In the present embodiment, when the distance between the vehicle 200 and the electricity source device 100 is shorter than the vehicle approach threshold value, the signal receiving section 12 is initialized before the sending section. signal 23. This makes it possible to avoid situations where even though a signal is emitted from the signal sending section 23, the signal receiving section 12 is not initialized to receive the signal.
    [071] In the present embodiment, the electricity source device 100 includes: the wireless communication section 12 which performs wireless communication with the wireless communication section 24; the signal receiving section 13 which performs wireless communication with the signal sending section 23; and the control section 15. The electricity source device 100 senses the distance between the vehicle 200 and the electricity source device 100 based on the output of the wireless communication section 24; and initializes the signal receiving section 13, and perceives the position relationship between the power supply coil 12 and the power receiving coil 22, when the distance is shorter than the vehicle approach threshold value. This makes it possible to initialize the signal receiving section 13, and receive the signal, when the vehicle 200 is positioned on the power supply coil 12, and thereby, prevent radio wave leakage due to the signal, and suppress interference from radio wave with external peripheral devices. Since the signal receiving section 13 does not need to be constantly energized in this embodiment, it is possible to reduce radio wave leakage from the signal receiving section 13, and thereby suppress influences to external peripheral devices such as a smart key system and a tire air pressure monitoring system.
    [072] In the present embodiment, the vehicle 200 includes: the wireless communication section 24 which performs wireless communication with the wireless communication section 14 and serves to perceive the distance between the vehicle 200 and the electricity source device 100; the signal sending section 23 which performs wireless communication with the signal receiving section 13 and serves to perceive the positional relationship between the power supply coil 12 and the power supply coil 22; and the load control section 25; where the vehicle 200 initializes the signal sending section 23 when the distance to the electricity source device 100 is shorter than the vehicle approach threshold value. This makes it possible to initialize the signal sending section 23 and receive the signal when the vehicle 200 is positioned on the power supply coil 12, and thereby, prevent radio wave leakage due to the signal, and suppress radio wave interference. radio with external peripheral devices. Since the signal sending section 23 does not need to be constantly energized in this embodiment, it is possible to reduce radio wave leakage from the signal sending section 23, and thereby suppress influences to external peripheral devices, such as a system. of smart key and a pneumatic air pressure monitoring system.
    [073] Although the signal receiving section 13 is composed of four antennas in the present embodiment, the signal receiving section 13 is not limited to this configuration, but can be composed of several antennas other than four. The signal receiving section 12 need not be provided on the ground side, but may be provided on the vehicle 200. The signal sending section 23 need not be provided on the vehicle 200, but may be provided on the ground side. In the present embodiment, the signal sending antenna of the signal sending section 23 and the signal receiving antennas 13a, 13b, 13c, 13d of the signal receiving section 13 constitute the various sensors. However, the various sensors need not be constituted by the pair of signal sending section 23 and signal receiving section 13, but can be constituted by sensors provided only on the ground side and on the vehicle side 200. For example, detection Foreign object detection and coil position perception can be implemented by providing various infrared sensors on the ground side, which infrared sensors emit light towards the vehicle 200, and refer to the power of the reflected infrared light.
    [074] Although the foreign object detection section 153 detects a foreign object based on the differences between the output values of the signal receiving antennas 13a, 13b, 13c, 13d in the present embodiment, the foreign object detection section 153 can detect a foreign object by processing the output values of signal receiving antennas 13a, 13b, 13c, 13d by multiplication, addition, or subtraction, and comparing the results of the calculations.
    [075] In the present embodiment, the foreign object detection section 153 can perform foreign object detection while electrical power is being supplied from the power supply coil 12 to the power receiving coil 22. When the foreign object detection section 153 detects a foreign object during the supply of electrical power, the control section 15 then stops sending electricity from the power supply coil 12, and notifies via wireless communication the vehicle 200 of the event the foreign object is present.
    [076] Since the distance measurement based on communication between the wireless communication section 14 and the wireless communication section 21 is greater in unit of measurement than the perceived coil position deviation based on the communication between the signal receiving section 13 and the signal sending section 23, the communication cycle between the wireless communication section 14 and the wireless communication section 24 can be set longer than the communication cycle between signal receiving section 13 and signal sending section 23. The amount of data sent by communication between signal communication section 13 and signal sending section 23 may be small, due to communication Bidirectional control signal cannot be performed between the signal receiving section 13 and the signal sending section 23 as between the wireless communication section 14 and the wireless communication section 24.. However, it is preferable to run a check tion of parity during the system check, so as to improve the position deviation accuracy between the coils.
    [077] Position sensing section 152 can perform coil position sensing while electrical power is being supplied from power supply coil 12 to power receiving coil 22. control 15 can be controlled to shut down the power supply for a predetermined period after running the power supply, and sense the position of the coils by the position sensing section 152 while the power supply is being stopped, and after the perception, restart the electricity supply. This makes it possible to confirm whether or not the coil position deviation occurs during electrical power supply. Although the distance between the vehicle 200 and the electricity source device 100 is measured based on the strength of the signal received by the wireless communication section 14, it can be measured based on a time difference around the received signal or something similar. As a communication device for remote communication for measuring distance, a sensor can be provided which directly measures the distance between the vehicle 200 and the electricity source device 100.
    [078] One of the power supply coil 12 and the power receiving coil 22 corresponds to the first coil of the present invention, while the other coil corresponds to the second coil of the present invention. The wireless communication section 14 and the wireless communication section 24 correspond to the first communication device of the present invention. The signal receiving section 13 and the signal sending section 23 correspond to the second communication device of the present invention. Control section 15 and load control section 25 correspond to the control device of the present invention.
