    [0001] The invention relates to the field of ground power systems for unguided electric vehicles and their methods of use. Electrically propelled vehicles are seen as an alternative to thermally propelled vehicles, with the aim of reducing greenhouse gas emissions. An electric vehicle has a rechargeable battery and an electric motor, powered by the battery and to propel the vehicle. For unguided electric vehicles (ie trucks, vans, passenger cars, etc.) it is known to recharge the vehicle's battery, when it is stopped, by connecting the battery to a charging station, by means of an electric cable.
    [0002] It has also been proposed to recharge the battery of an unguided electric vehicle during its journey. To do this, two types of systems are considered: induction power systems and conduction power systems. Among the conduction feed systems, the document WO 2010 140964 discloses a roadway whose surface is provided with two grooves parallel to each other and extending longitudinally in the direction of the roadway. Inside each of the grooves circulates one or more electrical power supply rails. To capture the electric current, the unguided electric vehicle is provided with a pole whose end is adapted to penetrate into the grooves of the roadway so as to come into electrical contact with the supply rails. The feed rails are subdivided into longitudinal segments. A segment is connected to a voltage source through a switch that is controlled according to a signal relating to the position of the vehicle to be powered. In the aforementioned document, this position signal is generated during the detection carried by the vehicle, by a magnetic loop integrated into the roadway and flowing along the segment in question, of a RFID type label (for "Radio Frequency Identification"). in English). Upon receipt of such a position signal, a controller closes the switch so that the segment under consideration is electrically connected to the voltage source.
    [0003] The object of the invention is to propose an improved conductive type ground feeding system.
    [0004] The subject of the invention is a ground supply system for a non-guided electric vehicle, having a pair of supply tracks comprising a so-called phase-specific conducting track adapted to be brought to a supply voltage, and a conductive track called neutral for the return of the current, the neutral track flowing parallel to the phase track and the phase track consisting of a plurality of rectangular segments, arranged end to end, each segment being electrically isolated from its neighbors characterized in that - the system comprises a first voltage source capable of delivering a low supply voltage and a second voltage source capable of delivering a high supply voltage; each segment is connected by a selection means controlled either to the first source or to the second voltage source; - The system comprises at least one speed measuring means for measuring the instantaneous speed of an unguided electric vehicle traveling on a section of a roadway equipped with the system; and a selection device adapted to acquire the instantaneous speed of a vehicle measured by the speed measuring means, to compare the speed measured at a threshold speed and to control the or each selection means according to the result of the comparison.
    [0005] According to particular embodiments, the system comprises one or more of the following characteristics, taken in isolation or in any technically possible combination: the selection device is such that if the measured speed is less than the threshold speed, the or each selection means is controlled so that each segment of the section is connected to the first source; and if the measured speed is greater than or equal to the threshold speed, the or each selection means is controlled so that each segment of the section is connected to the second voltage source. each segment of the phase-conductive track is electrically connected to the controlled selection means via a controlled switch, able to be tilted by a control means as a function of the presence of a vehicle in line with the segment in question or on a adjacent segment, for applying to the relevant segment of the phase track, the supply voltage delivered by the voltage source selected by the selection means. the first voltage source is capable of delivering a voltage lower than 60 V and a power compatible with the operation of auxiliary electric means of the vehicle to be powered, and the second voltage source is capable of delivering a high voltage and a power compatible with the operation of the main electrical means of the vehicle to be powered. the speed measuring means is a speed measuring unit comprising a computer connected to a speed sensor, the sensor being able to generate a signal from which the computer is able to determine a measurement of the speed of a vehicle; traveling on the section of roadway. the speed measuring means is a speed measuring system comprising a computer connected to a plurality of antennas, each antenna being associated with a segment and comprising at least two lobes distant from each other in a longitudinal direction; of the roadway, each antenna being adapted to pick up a signal emitted by a suitable transmitter provided with a pad of the vehicle, and to generate a signal from which the computer is able to determine the instantaneous speed of the vehicle. - The antenna of the speed measuring means is asymmetrical so as to allow the determination of the direction of the instantaneous speed of the vehicle. The invention also relates to a method of using a ground power system according to the above system, comprising the steps of: - acquiring a measurement of the instantaneous speed of a vehicle; - compare the speed measured at a threshold speed; and, if the measured speed is less than the threshold speed, controlling the selection means of each segment of a section of roadway on which the vehicle is traveling so that it is connected to the first voltage source, capable of delivering a voltage low power supply; or if the instantaneous speed is greater than or equal to the threshold speed, controlling the selection means of each segment of a section of roadway on which the vehicle is traveling so that it is connected to the second voltage source, capable of delivering a high supply voltage. The invention will be better understood on reading the following description of a particular embodiment, given solely for illustrative and non-limiting purposes, and with reference to the appended drawings, in which: FIG. 1 is a view back showing schematically an unguided electric vehicle traveling on a floor equipped with the ground supply system according to the invention; FIG. 2 is a view from above of FIG. 1; FIG. 3 is a schematic representation of a first embodiment of the ground supply system according to the invention; FIG. 4 is a block diagram of a method of using the system of FIG. 3; and, - Figure 5 is a schematic representation of a second embodiment of the ground power system according to the invention. With its experience in the field of ground-type conduction systems, for guided electric vehicles, that is to say, forced to move along tracks (especially trams moving along of railroads), the plaintiff to develop the present ground power system for unguided electric vehicles. Figures 1 and 2 show a car 1, as an unguided electric vehicle, traveling on a roadway 2. Of course, different types of unguided vehicles will be driven on the road 2 using the system of ground feeding. Thus, the term unguided electric vehicle includes freight trucks, passenger coaches, passenger cars, motorcycles, etc. An XYZ trihedron is conventionally associated with the car 1: the X axis in the longitudinal direction, oriented towards the front; the Y axis in the transverse direction, oriented from left to right; and the Z axis in the vertical direction, oriented from bottom to top. The car 1 comprises a body 4 and wheels 3, some of which are guidelines. The car 1 comprises steering means (not shown) allowing a driver to change the angle of the steering wheels in the XY plane so as to direct the vehicle 1.
    [0006] The car 1 comprises a rechargeable battery and an electric motor (not shown). In traction, these main electrical means require a power of the order of 30 kW. The car 1 is equipped with a pick-up means making it possible to collect electrical power during the movement of the car 1. The pick-up means are generally referenced by the numeral 5 in FIG. 1. The pick-up means 5 comprises a clean pad to be put in sliding contact on a pair of feeder tracks of the ground feeding system, which will now be described. The floor 2 comprises a trench 6 inside which is positioned the ground supply system, generally referenced by the numeral 10.
    [0007] Once the system 10 placed in position in the trench 6, it is filled with concrete 7 so that the upper surface 8 of the roadway 2 is continuous over the entire width thereof. The upper surface 8 is substantially planar. In position, the system 10 has, flush with the surface 8 of the roadway 2: a conductive phase track 11, intended to be electrically connected either to a first source of electrical power, or to a second source of electrical power, or to the surrounding earth potential, as will be described below; a conductive neutral track 12 intended to be electrically connected to a reference potential Vref, for example of 0 V; - A protective conductive track 13, intended to be electrically connected to a ground potential Vterre. The phase track 11 consists of a plurality of segments (11.i in FIG. 3) which, in the embodiment currently envisaged, each have a width of 10 cm and a length of 22 m.
    [0008] The segments are arranged end to end to form the phase track 11. The segments are electrically isolated from each other. Advantageously, the neutral track 12 is made using segments identical to those used for the phase track 11. Thus, the track 12 consists of a plurality of segments (12.i in FIG. about 10 cm and a length of about 22 m. The insulation between the consecutive segments of the neutral track 12 is here of the same nature as that of the phase track 11. However, although segmentation is necessary for mechanical reasons (expansion), the level of dielectric strength between segments is not necessarily as high as that between segments of the phase track 11. The neutral track 12 flows parallel to the phase track 11, on a first side thereof. The lateral edge of the phase track 11 and the lateral edge of the neutral track 12, which are opposite one another, are spaced apart by a first distance of about 15 cm.
    [0009] The protective track 13 is constituted by the upper face of a profile 14 sealed in the concrete 7 filling the trench 6. In the presently preferred embodiment, the profile 14 has an "I" shaped section, of which the central core is disposed substantially vertically. The protective track 13 is arranged parallel to the phase track 11, on a second side thereof. This second side is opposite the first side of the phase track 11 comprising the neutral track 12.
    [0010] The lateral edge of the phase track 11 and the lateral edge of the protective track 13, which are opposite one another, are spaced apart by a second distance of about 15 cm. The function of the protective track 13 is to form, on the second side, a means for collecting electrons of a leakage current from the phase conducting track 11. The current leaks to the first side are collected by the Neutral track 12. In the embodiment envisaged, the width of the protective track 13 is about 5 cm.
    [0011] With this particular choice of values for the transverse dimensions of the different tracks and their mutual spacing, the ground feeding system 10 has a total width of about 55 cm. This total width is chosen to remain smaller than the center distance of the smallest non-guided electric vehicle likely to circulate on the roadway 2 and to use the system 10.
    [0012] When the phase track 11 is brought to a high potential, any leakage of current, due for example to the presence of a puddle or a film of water on the surface 8 of the roadway, is collected on the first side by the neutral track 12 and on the second side by the protective track 13. This prevents the portion of the surface of the roadway brought to a high potential does not extend laterally beyond the width of the supply system 10. By choosing the total width of the ground feeding system 10 less than the center distance of the smallest vehicle allowed to circulate on the floor 2 and clean to use the system 10, it is ensured that if a pedestrian is located laterally on the first or second side of a segment of the phase track 11, but beyond either the neutral track 12 or the protective track 13, the pedestrian will not be electrocuted if this segment is worn at a high potential. To facilitate the implementation of the system 10, it comprises a support assembly of the different tracks. The support assembly comprises a base 20 carrying two support profiles 25 and 26, identical to each other, and serving as an insulating support for the conducting tracks of phase 11 and neutral 12. These tracks are mechanically fixed to the support profiles, but are electrically isolated from them. The base 20 also carries the profile 14. An electric cable 28, fixed to the core of the section 14, is intended to be buried in the roadway 2, advantageously beyond the trench 6, so as to put the track of protection 13 to the earth potential Vterre, and by electrical continuity the base 20.
    [0013] The base 20 is provided with a plurality of drawers 29, adjustable in height, adapted to be stuck in the bottom of the trench 6 so as to preposition the feed system by the ground 10 so that the level of the tracks are flush with the surface 8 of the roadway 2 to achieve.
    [0014] Then, concrete is poured so as to drown the support assembly. The support profiles 25 and 26 as well as the profile 14 are then sealed in the concrete layer 7. Advantageously, the state of the upper surface of the concrete layer is worked to present an adhesion adapted to the tires of vehicles traveling on the road. floor 2.
    [0015] The pair of feed tracks, consisting of the phase track 11 and the neutral track 12, as well as the protective track 13 are flush with the surface 8 of the roadway 2. More specifically, the tracks 11 and 12 make slightly protruding above the surface 8 of the roadway 2, for example a height of the order of a few millimeters, in particular equal to 2 mm. Runway 13 is at surface level 8 of carriageway 2.
    [0016] An electrical diagram of the system 10 is given in Figure 3. The system 10 is subdivided into longitudinal sections. The section Dj is located between adjacent sections Dj-1 and Dj + 1. A section Dj corresponds to a plurality of segments 11.i of the phase track 11. In FIG. 3, ten segments 11.i compose a section Dj.
    [0017] Each segment of the plurality of segments 11.i of a section Dj is electrically connected via a dedicated switch 30.i dedicated to a supply line 34. The supply line 34 is common to different segments 11.i of the section Dj considered. The supply line 34 of the section Dj is connected, via a selection means 38, either to a first source of electrical power 35, or to a second source of electrical power 36, or to the potential of the surrounding earth. The source 35 is clean for example to deliver a low voltage Vs, 48 V DC. The source 35 is in fact a relay station capable of converting a three-phase current into a two-phase current.
    [0018] The source 36 is clean for example to deliver a high voltage Vs2 of 750 V DC. The source 36 is in fact a relay station capable of converting a three-phase current into a two-phase current. The selection means 38 is controlled by a selection device 39 adapted to acquire a speed measurement delivered by a speed measuring means.
    [0019] In the first embodiment, the speed measuring means is a speed measuring unit 40 fitted to each road section Dj.
    [0020] The unit 40 comprises a speed sensor 4lconnected to a computer 42. For each vehicle traveling on the road section Dj, the sensor 41 is able to generate a measurement signal, from which the computer 42 is able to determine a measurement. the instantaneous speed of the vehicle.
    [0021] The selection device 39 comprises: an acquisition module suitable for acquiring a speed measurement made by the speed measuring unit 40; a comparison module capable of comparing the measurement of the instantaneous speed acquired, at a threshold speed Vo, of 60 km / h for example; and a clean control module, depending on the result of the comparison, to switch the selection means 38 to a first position, for connecting the supply line 34 to the first source 35, or in a second position, allowing to connect the power line 34 to the second source 36.
    [0022] Each switch 30.i is controlled by a dedicated control device 50.i adapted to acquire a position signal delivered by a position measuring means comprising a calculator 51.i connected to an antenna 52.i. The antenna 52.i travels in the roadway 2, to form a loop around the corresponding segment 11.i, so as to detect the presence of a vehicle above the segment 11.i. More specifically, the antenna 52.i flows in longitudinal channels provided in each of the lateral edges of the support section 25 of the phase track. The vehicle is equipped with a shoe comprising a transmitter 53 (FIG. 1) suitable for transmitting, continuously, a radio signal having, for example, a characteristic frequency of 500 kHz.
    [0023] The signal collected by the antenna is applied to the input of the computer 50.i which is able to determine a measurement of the position of the vehicle and to transmit it to the control device 50.i. When detecting a car 1, the control device 50.i is adapted to close the switch 30.i.
    [0024] The method of using the system just described is as follows. When a car 1 enters the section Dj, the speed measuring unit 40 measures its instantaneous speed V (step 110). The selection device 39 acquires this value of the instantaneous speed, delivered at the output of the speed measuring unit 40, and compares it with the threshold speed Vo (step 120).
    [0025] When the measured speed is lower than the threshold speed Vo, for all the vehicles traveling on the section, the selection device 39 switches the selection means 38 in the first position to connect the supply line 34 to the first source 35 ( step 130).
    [0026] On the other hand, when the speed measured for at least one of the vehicles traveling on the section in question is greater than or equal to the threshold speed Vo, the selection device 39 switches the selection means 38 into the second position to connect the line supply 34 to the second source 36 (step 140). The car moves along the Dj section.
    [0027] The controlled switches 30.i of the segment Dj are open by default. When the position sensor 51.i detects the presence of the car 1 above the segment 11.i (step 140), the control device 50.i closes the switch 30.i to connect the segment 11.i to the feed line 34 (step 150). The switch 30.i remains closed as long as the position sensor detects the presence of the car. The different segments of the phase track 11 are successively activated (loop on i of FIG. 4) in synchronization with the displacement of the car 1 along the roadway 2. The collection means 5 of the car 1, rubbing simultaneously on the phase 11 and neutral 12 tracks, allows the capture of a supply current. A switching means of the collecting means 5 is able to determine the supply voltage. If the measured voltage is low, the supply current is used to recharge or operate the auxiliary electric means of the vehicle. If the voltage is high, the supply current is used to recharge the battery or operate the vehicle engine. Car 1 runs through the entire Dj section before moving on to the next Dj + 1 section. The process is then iterated on this new section. As indicated above, the potential of the segments is selected according to the speed of the car 1.
    [0028] If the car 1 is caught in a traffic jam and is traveling at a slow pace, the electric potential at which the phase track 11 is carried is possibly zero, in any case below a limit of 60 V beyond which a pedestrian risks be electrocuted. This low electric potential makes it possible to transfer a reduced power to the car, compatible with the operation of the auxiliary electrical means thereof.
    [0029] If the car 1 normally travels at a speed greater than the threshold speed which is associated with the section of the roadway on which the car is engaged, the electric potential at which the phase track 11 is carried is high. This high electric potential makes it possible to transfer a significant power to the car, compatible with the operation of the main electrical means of the car. It should be noted that the segments 11.i are fed successively, so that a segment or possibly two segments are at the potential of 750 V at a given instant. Thus, the portion of the surface of the roadway carried to a potential, dangerous for a pedestrian, does not extend longitudinally beyond the length of one segment or two segments at most. For this reason, the length of the segments is chosen to correspond substantially to the distance traveled during the time of evasion in front of the vehicle or access to the driver segment behind the vehicle, the vehicle traveling at 60 km / h. Thus, the appropriate selection of the voltage source as a function of the speed of the vehicle to be powered contributes to the safety of the system 10. Many variants of the method of using the ground feeding system are conceivable. Thus, when several vehicles are engaged simultaneously on the section Dj of the roadway, it is the vehicle whose speed is the highest that triggers the tilting of the means for selecting the first position to the second position, or conversely as indicated ci -above.
    [0030] A second embodiment will now be presented with reference to FIG. 5. In this figure, an element identical to an element of the first embodiment is referenced by the reference numeral used in FIGS. 1 to 3 to designate this identical element. .
    [0031] In this second embodiment, the speed measuring means is a speed measuring system 140 comprising a plurality of antennas 141.i connected to a computer 142. Each antenna 141.i is associated with a segment 11.i. An antenna 141.i forms a loop implanted in the ground, just upstream (depending on the direction of traffic on the roadway) of the segment 11.i associated.
    [0032] The antenna 141.i flows for example in the channels provided on the edges of the support profile of the neutral track. The antenna is shaped to define at least two lobes distant from each other by a determined interval along an axis of the antenna. The antenna is implanted so that the two lobes are arranged successively in the longitudinal direction of the roadway.
    [0033] The first lobe has a length of about 1 meter, while the second lobe has a length of about 50 cm. The two lobes are separated by an interval of 50 cm. The antenna is able to pick up the signal emitted by the transmitter 53 fitted to the pad of a vehicle, when this pad passes within about 15 cm of the antenna 141.i. The corresponding signal is applied to the input of the computer 142, which is able to determine a measurement of the instantaneous speed of the vehicle. The signal generated by the antenna 141.i corresponds to the signal emitted by the transmitter 53 of the vehicle, convoluted with a slot function corresponding to the shape of the antenna 141.i and the instantaneous speed of the vehicle. In the present case, the slot function comprises a first high level corresponding to the first lobe, a low intermediate level corresponding to the interval between the first and second lobes, and a second high level corresponding to the second lobe. The first high level has a duration substantially twice as long as that of the second high level. Thus, the geometrical asymmetry of the antenna makes it possible to determine the direction of traffic of the vehicle on the roadway. The duration of each level makes it possible to accurately determine the instantaneous speed of the vehicle. The calculated speed is passed to the selection device 39 of the voltage level to be applied to the phase track. As a variant of this embodiment, the antenna may comprise more than two lobes spaced from one another spatially so as to determine an instantaneous speed of the vehicle in safety. It should be noted that the value of the threshold speed was determined according to the length of a segment. Indeed, at the threshold speed, the distance of evasion in front of the vehicle or access behind the vehicle is equal to the length of a segment of the track. Consequently, for a pedestrian the danger does not come from a risk of electrocution during the supply of the segment, but to be crushed by the vehicle itself. For a segment of 22 m and the minimum braking distances indicated by road safety, the threshold speed is about 60 km / h.
