- the station S is also equipped with a signaling system 16 with traffic lights arranged to be visible to the driver of the electric vehicle V, and a photocell 14 provided for detecting the positioning of the vehicle V.
- An essential condition for enabling the charging process is that the vehicle V is suitably positioned relative to the station S, both longitudinally (X axis) and laterally (Y axis).
- the roadway 17 along the station S can be provided with two parallel strips 180, 181 allowing the driver to position his vehicle V to a predetermined lateral position Yo.
- a marker may be provided on the sidewalk bordering the station S.
- the driver of the vehicle V estimates the position of this marker on the center of the front wheel, by means of a rear-view mirror.
- Two transverse strips 170, 171 may also be provided on the floor 17 to assist the driver of the vehicle V in its longitudinal positioning by placing the front wheels of the vehicle V between these two transverse strips ( Figure 2).
- the pavement 17 can thus be equipped with:
- the optimal longitudinal positioning Xo is achieved.
- the positioning assistance system 1 according to the invention is distributed between the vehicle V and the charging station S.
- the vehicle V comprises, in the context of this assistance, in addition to the retro-reflector 24, a wireless transmission-reception unit 23 for communicating with the station S, a presence detection unit 27 of the mobile male coupling part. 110 near a receiving cone 28 of the coupling device 20, an end of charge detection unit 25 associated with a device 200 for storing energy (DSE), a remote control 21 actuated by the driver to control a load and to control a taxi, and a man-machine interface 26 provided within the cockpit of the vehicle V.
- DSE energy
- the station S comprises, under the assistance system 1 according to the invention, in addition to the signaling system 16 and the photocell 14, an end-of-travel detection unit 15 associated with the actuating device 100, a unit 13 wireless transceiver for communicating with the vehicle V, and an infrared receiving unit 18 for receiving infrared signals from a remote control.
- the vehicle V functionally comprises an electric traction chain (ETC) 210 connected to the energy storage device 200 with which energy transfers are carried out, and a control and processing unit (CPU) 22 receiving an end signal.
- ETC electric traction chain
- CPU control and processing unit
- the control and processing unit 22 is designed to generate graphic information, such as icons, representative of the information of interest for the positioning and loading operations and configured to be displayed on the human-machine interface 26, and a rolling blocking signal BR for the electric power train 210.
- the station S functionally comprises, in addition to the electrical energy supply device 10, the actuating device 100 and the signaling system 16, a control and processing unit 12 receiving as input:
- the control and processing unit 12 is designed to generate, in response to the processing of the aforementioned signals:
- an activation signal AC of the energy supply device 10 when the electromechanical coupling has been put in place and the control and processing unit 12 of the station has received a charge command from the V vehicle. It is also possible to integrate the automatic removal of the mobile coupling arm at the end of charging. This secures the operation because there is no waiting time between the action of the driver, and the total withdrawal of the arm. This waiting time was unnatural, and possibly variable. The driver thus waits for the signal to fire, conditioned by the end of the arm stroke.
- the flashing orange is activated in case of a persistent station alarm even after acknowledgment by the driver's remote control
- the vehicle V is in approach of the station S.
- the driver positions his vehicle laterally so as to reach an appropriate lateral positioning Yo with respect to the station S.
- the signaling system 16 is off indicating to the driver that he can still ride on the roadway 17.
- phase 2 the vehicle V approaches its optimum longitudinal position Xo, the driver being assisted by the visual reference mark by means of the mirror.
- the retro-reflector 24 When the retro-reflector 24 is in front of the photocell 14 (phase 3), the latter emits an X-ray detection signal CX which is processed by the control and processing unit of the station S with consequent modification the signaling displayed on the signaling system 16 which turns green flashing. The driver is thus warned that the appropriate positioning is well achieved and that he can stop his vehicle.
- the driver can then activate (phase 4) the charge control button of his remote control 21.
- the infrared charge control signal SC is then received by the infrared reception unit 18 and processed by the control and processing unit. 12 which in turn generates a DC charge control signal to the actuator 100.
- This has the effect of initiating the lateral deployment of the movable coupling arm 11 which will engage the connection cone 28 of the coupling device 20 of the vehicle V. From the beginning of this deployment phase 5 and the setting in motion of the arm, the signaling system turns red and will remain so throughout the charging phase that follows and until the complete withdrawal of the arm .
- the end of charge detection unit 25 transmits an end of charge signal DC which is transmitted locally to the control unit and processing 22 within the vehicle V. This signal is also transmitted, via the wireless communication channel 13, 23, to the charging station S. The signaling is kept red, thus indicating to the driver that no rolling n is still allowed at this stage.
- the end of charge information is displayed on the man-machine interface 26 of the vehicle V and is processed at the station S by its control and processing unit 12 with the effect of deactivating the supply of energy.
- the achievement of the time level setpoint causes an automatic disconnection at the end of charging, with the disengagement of the mobile coupling arm.
- the latter informed of the end of the charging process, can then actuate (phase 8) the "request taxi” button on his remote control 21 which then emits an infrared signal SR rolling request which is received by the charging station S via the infrared reception unit 18 and then processed by the control and processing unit 12 to transmit a disconnection control signal CD to the actuating device 100.
- phase 9 engages the disengagement of the coupling arm 11 which leaves the coupling cone 28 (phase 9).
- the signaling is kept red because the mobile coupling arm is still deployed and premature rolling could damage the vehicle.
- a delay after disconnection is provided at the vehicle: the driving is prohibited during this time, to ensure that the driver does not grill the fire.
- a limit signal FC is emitted by the end-of-travel detector 15, received and processed by the control unit.
- control and treatment 12 which then emits green signaling, thus indicating to the driver that he can resume taxi V.
- the use of the remote control 21 can be replaced by a driver action on a dashboard or on a man-machine interface.
- This action can for example implement a touch screen type or contactless with gesture recognition.
- the safety of the positioning method can be reinforced by providing a mechanical locking system and / or as long as the coupling arm is detected near the receiver cone installed on the roof of the vehicle.
- the invention is not limited to what has just been described and many other embodiments than those which have just been described are conceivable.
- the invention is not limited to particular configurations and geometries of vehicles or charging stations.
- the vehicles can in particular combine different energy sources or different modes of traction.
- the charging stations can also provide additional services in addition to the charging function.
