    [0001] The present invention relates to the autodidaxy of the position of a charging device (in particular a primary coil) of a charging station or a charging station. charging infrastructure for vehicles equipped with an electric motor. Document US 2014/0092236 A1 discloses a positioning system for a vehicle, said vehicle being positioned relative to a charging station by means of a camera disposed outside the vehicle. DE 10 2011 006 504 A1 discloses a method for positioning a motor vehicle relative to a charging station or battery exchange station. WO 2010/060720 A2 discloses a method for automatic recharging of vehicles. To do this, the vehicle is brought in a self-controlled manner from a transfer area to a selected charging location and from there to a receiving area. An (automatic) positioning of an electric vehicle over an induction charging platform is known from the state of the art. The output at the time of inductive charging of a vehicle energy accumulator via a recharging terminal depends, in this case, decisively on the correct orientation of the primary coil of the charging terminal with respect to the secondary coil of the vehicle. Accordingly, the object of the present invention is to improve over the state of the art the charging (particularly inductive) wireless of the vehicle energy accumulator by means of a charging station. This object is solved according to the invention by a method for determining a charging position for a vehicle with respect to a charging device 3029862 2 of a charging station, the method comprising the following steps: detection of a marking the charging station; moving the vehicle to a first position depending on the marking and a relative position, which indicates a position of the charging device of the charging terminal with respect to the marking, so as to position a vehicle charging device near the device charging the charging station; and determining, from the first position, a second position of the vehicle as a load position by optimizing a coupling between the vehicle load device and the charging device of the charging terminal.
    [0002] According to specific provisions of this method, which can be combined: optimization is performed according to a yield that is obtained during a charging process, during which the charging station recharges the vehicle using the charging device the charging station and the vehicle charging device; the method comprises a movement of the vehicle towards the second position; the charging device of the recharging terminal and the charging device of the vehicle are made for an inductive charging of a vehicle energy accumulator; the method comprises a correction of the relative position stored on the basis of the second position, so that, during a subsequent charging process, the displacement of the vehicle according to the marking and the corrected relative position brings the vehicle in the position corresponding to the load position, without the vehicle previously rolling in the position which is a function of the marking and the uncorrected relative position; The method comprises a detection of the relative position by means of a wireless communication link; the correction of the relative position is signaled by the vehicle to the charging terminal via the wireless communication link, and the relative position is changed when different vehicles signal to the charging station that the relative position is corrected by the same way ; the movement of the vehicle according to the marking 10 and the relative position is effected, in addition, according to another relative position, which indicates the position of the vehicle load device with respect to the vehicle, and the other Relative position is changed when, for the same vehicle in different charging stations, the relative position is corrected in the same way. The present invention also provides a vehicle device, which is configured to determine a charging position of a charging device of a charging station; The device comprising detection means for detecting a marking of the charging terminal, and control means; the device being configured to promote a displacement of the vehicle according to the marking and a relative position which indicates a position of the charging device of the charging terminal with respect to the marking, to a first position, in which a charging device of the vehicle is disposed near the charging device of the charging terminal, and for determining with the aid of the control means, from the first position, a second position of the vehicle as a charging position, by optimizing the a coupling between the vehicle charging device and the charging device of the charging terminal.
    [0003] This device can be configured for implementing the method as defined above. In the context of the present invention is proposed a method for determining a load position for a vehicle with respect to a charging device of a charging station. The method according to the invention comprises the following steps: - detection of a marking of the charging station. The term marking in this case generally refers to a marking or marker in support of which it is possible to determine the exact position of the charging device of the charging station. The marking is detected in particular by optical detection means. 15 - moving the vehicle to a first position according to the marking and a relative position, which defines the position of the charging device of the charging terminal with respect to the marking, so as to position a vehicle charging device on the as close as possible to the charging device of the charging station. Moving can only be done manually, assisted (ie assisted by the vehicle) or all automatically. Therefore, in this step, the vehicle is brought into the first position from a position, in which marking can be detected. Determining a second position of the vehicle from the first position by optimizing a coupling between the vehicle charging device and the charging device of the charging terminal. The second position corresponds to the load position to be determined. In an inductive charging process, the second position in particular and, therefore, the charging position is determined so as to optimize the inductive coupling between the vehicle charging device and charging device of the charging terminal.
    [0004] The optimization of the coupling between the charging device of the vehicle and the charging device of the charging terminal makes it possible to improve an inductive charging process compared with the state of the art, since the optimized coupling makes it possible, in a predetermined time interval, charging in the vehicle energy accumulator, from the charging terminal, a higher load than in the state of the art in which the coupling is not optimized.
    [0005] Optimization of the coupling is advantageously effected according to a yield which is obtained during a charging process. During the recharging process, the charging station, using the charging device of the charging station and the vehicle charging device, recharges the vehicle's energy storage. The inductive coupling applies, in this case in particular, all the better that the efficiency obtained during the charging process is high. In order to optimize the coupling according to the efficiency, the vehicle is advantageously moved to a determined position starting with the first position. In the determined position, the efficiency is calculated during a short inductive charging process (for example with a load efficiency of 10%). Then, the vehicle is moved into a new determined position, in which the yield for the new determined position is again calculated in support of a test measurement (i.e. in support of the short process inductive charging). In this procedure, the second position, more precisely the load position, corresponds to the determined position, in which the highest efficiency is obtained in all the determined positions. In this case, the efficiency indicates in particular a ratio between a charge delivered to the vehicle by the charging station during a recharging process and a charge received by the vehicle in its energy accumulator during the recharging process. . Advantageously, the vehicle is then moved into the second position or load position, for the actual refill. As already mentioned above, the charging device (for example, an induction charging platform) of the charging terminal and the vehicle charging device are configured according to a preferred embodiment of the invention for the purpose of inductive charging of a vehicle energy accumulator. It should be emphasized, however, that the present invention can be generally used for wireless or non-contact energy transmission, such as a capacitive charging process or an electromagnetic charging process (in this case, the transmission of energy is done via antennas). According to the invention, the relative position, which defines the position of the charging device of the charging terminal 20 with respect to the marking, can be corrected according to the second position or charge position, defined beforehand. Therefore, during the next recharging process at the same charging station, the vehicle can be brought, depending on the marking and the corrected relative position, immediately into the first position which corresponds, in this case, to the position. load, without the vehicle being first brought to a position which has been determined in support of the marking and the uncorrected relative position.
    [0006] In other words, after determining the second position or load position, it is checked whether the second position is different from the first position. If so, the relative position is corrected so that the corrected relative position defines the position of the load device of the refill terminal with respect to the marking according to the second position or load position. The relative position of a charging station can, on the one hand, be stored in the vehicle according to the respective charging station. On the other hand, the relative position of the respective charging station can be detected by means of a wireless communication link between the charging station and the vehicle or between the vehicle and any source (for example, in the Internet). ), which includes information on the relative position. The detection of the relative position via a wireless communication link has, in this case, the advantage that it is also possible to determine the relative position of a newly established or previously unknown charging station of the vehicle. . On the other hand, the fact that the relative position of the respective charging terminal can be stored inside the vehicle has the advantage that the memorized relative position can be corrected by the vehicle itself. It is obvious that the two variants can also be combined, since the relative positions for unknown charging stations of the vehicle are detected via a wireless communication link, whereas the relative positions of the charging stations known to the vehicle are stored in the vehicle. According to a preferred embodiment according to the invention, the vehicle signals to the charging terminal, by means of a wireless communication link, a corrected relative position. When a sufficiently large percentage of vehicles, which are recharged by the charging station, signals a similar correction of the relative position, the charging station changes its relative position accordingly.
    [0007] This embodiment of the invention offers the possibility of correcting the relative position of the respective charging terminal, which is transmitted to the vehicles via the wireless communication link. When the same correction need is transmitted by different vehicles to the charging system or to the charging station, this indicates a systematic error which can be advantageously corrected by this embodiment. If the detected erroneous divergence of the relative position is too great, a corresponding error may occur in the charging station and the charging terminal may be signaled as not being ready for use by, for example, a system operator an infrastructure operator at the charging station. In this case, a technician should be called in to correct the error.
    [0008] As a general rule, the step of moving the vehicle in the first position does not depend only on the marking and the relative position, but also depends on an additional relative position which defines the position of the vehicle load device relative to the Vehicle (or more precisely with respect to a highlight of the vehicle, such as the middle of the median longitudinal axis of the vehicle). When, for the same vehicle, the relative position has been corrected in the same way in different charging stations, this signals another erroneous relative position, so that the other relative position is correspondingly modified. In other words, when in different charging terminals the second position or charging position is shifted in the same way with respect to the first position, this indicates that the installation position of the charging device (for example, the secondary coil) of the vehicle deviates from the other relative position. Therefore, the other relative position is correspondingly modified so that on the next move to one of these charging terminals, the first position corresponds to the second position, the position of charge or optimal position therefore already corresponds to the first position. In the context of the present invention, there is also provided a device for a vehicle, which is configured to determine a charging position of a charging device of a charging station. The device according to the invention comprises detection means (for example, a camera) for detecting a marking of the charging terminal, and control means. The device is configured to promote vehicle movement according to the marking and a relative position which indicates a charging device position of the charging terminal with respect to the marking, to a first position, in which a charging device the vehicle is located as close as possible to the charging device of the charging station. With the help of the control means, a second position of the vehicle as a load position is determined from the first position, since a coupling between the vehicle load device and the load device charging station is optimized. The advantages of the device according to the invention substantially correspond to the advantages of the process according to the invention, which have been described in detail above, so that they will not be repeated here. Finally, in the context of the present invention is also proposed a vehicle which comprises a device according to the invention.
    [0009] The present invention makes it possible to improve the non-contact charging of a vehicle energy store by means of a charging station. By using the present invention, the primary coil of the charging terminal can be fixedly installed (and not mobile) at an advantageous cost. With the present invention, it is possible, by the use of sensors 3029862 10 (for example, a camera) of the vehicle, already present for other reasons, to carry out a calibration of the charging system without it being necessary. to use additional measuring devices.
    [0010] The present invention is particularly suitable for motor vehicles. It is obvious that the present invention is not limited to this preferred field of application, since the present invention can also be used for boats, aircraft, as well as railroad vehicles or guided on a track. The present invention is explained below in detail with reference to the single figure, in support of embodiments according to the invention. The single figure schematically shows a vehicle 15 according to the invention equipped with a device according to the invention. The single figure shows schematically a vehicle 10 according to the invention equipped with a device 20 according to the invention and a charging terminal 30. In addition to the device 20 according to the invention, the vehicle 10 comprises a secondary coil 11 to function charging device. The charging terminal 30 shown schematically comprises, in addition to a primary coil 31, a communication device 32 for wireless communication with the vehicle 10, and a memory 33. The device 20 according to the invention comprises control means 1, a camera 2, a communication device 3 for wireless communication with the communication device 32 of the charging terminal 30, and a memory 4. The invention is explained below in support of an example recharge process. The vehicle 10 according to the invention approaches the inductive charging terminal 30 to inductively recharge an unrepresented energy accumulator of the vehicle 10. Using the camera 2 is detected a marker visible from the terminal 30, which is located on the charging terminal, ideally in the visible vicinity of the camera 2. Depending on this marker and as a function of a relative position, the position of the primary coil 31 of the terminal of recharge 30 can be determined. If the vehicle 10 is located for the first time near the charging terminal 30, the relative position is still unknown. In this case, the device 20 of the vehicle 10 makes contact, via the communication device 3, with the communication device 32 of the charging terminal 30 to detect the relative position 10 which is stored in the memory 33 of the charging station 30 and store it in the memory 4 of the device 20. Next, the vehicle 10 rolls to a first position, in which the secondary coil 11 of the vehicle 10 is located near the primary coil 31 of the charging terminal 30. By means of inductive test charging (with, for example, short charge pulses of 10% of the charging power), it is possible to determine the efficiency for the first position. Then, the vehicle 20 is moved in the transverse direction, for example by appropriate movements of the steering wheel, another inductive test refill being performed in various positions to determine the performance of each position. The optimum position or load position is the position in which the highest yield is obtained. If the load position does not correspond to the first position, the relative position is corrected accordingly and is stored in the corrected form in the memory 4 of the device 20. The vehicle 10 according to the invention now has 30 for the charging station Corresponding to the exact relative position of the primary coil 31 and may, during the next charging process on this charging terminal 30, be moved according to the marker immediately in the optimum position. 35
