    Field of the invention
    The present invention relates to a method and a device for locating a motor vehicle in a parking lot. The invention also relates to a parking thus equipped and to a computer program for implementing the method.
    State of the art
    DE 10 2012 222 562 A1 discloses a parking management system for transferring a vehicle from a starting position to a destination position.
    To transfer the vehicle to its starting position at its destination position it is generally necessary to locate the vehicle in the parking. Since several vehicles are supposed to be in the car park, it is generally necessary to ensure that the appropriate vehicle is driven from its starting position to its destination position.
    Purpose of the invention
    The present invention aims to develop an effective concept of locating a vehicle in a parking lot.
    DISCLOSURE AND ADVANTAGES OF THE INVENTION To this end, the subject of the invention is a method for locating a vehicle consisting of issuing a request via a wireless communication network produced in the car park intended for a vehicle. predefined automobile, to request that vehicle to perform a predefined action, after issuing the request, check whether a vehicle that is in the parking has performed or performs the predefined action, if the verification shows that the vehicle in the car park has executed or will execute the predefined action, to authenticate the vehicle as the predefined vehicle and to locate this predefined vehicle at its instantaneous position. The invention also relates to a device for locating a vehicle comprising a communication interface for transmitting a request by a wireless communication network made in the car park, to a predefined vehicle for this vehicle to perform an action. predefined, a verification facility to check after issuing the request, whether a vehicle that is in the parking lot has executed or is about to perform the predefined action, an authentication facility to authenticate the vehicle as predefined vehicle that executes or has executed the predefined action and a location facility to locate the predefined vehicle at its instantaneous position.
    According to another development, the subject of the invention is a car park comprising such a device for locating a vehicle. The invention also relates to a computer program with a program code for implementing the method of locating a vehicle as defined above when the program is executed by a computer.
    Thus, the invention makes it possible in particular to efficiently locate a given vehicle consisting in executing a predefined action and to check whether a vehicle in the car park has executed, or is executing, the predefined action which makes it possible to define as a desired vehicle, the one who performed the predefined action or is running it and to whom the request was intended or considered. The instantaneous position of the vehicle that has executed the predefined action or is executing it thus corresponds to the position of the predefined vehicle, which allows an efficient location of the predefined vehicle.
    This also means that the invention is based in particular on the fact that it will be possible to locate and authenticate the predefined vehicle to which it has been asked to perform a predefined action.
    This notably allows, advantageously, to identify efficiently and with certainty the predefined vehicle among several vehicles in the parking. Indeed, the vehicles, to which the request was not intended, can certainly receive this request via the wireless communication network, but these vehicles will not perform the predefined action. Only the vehicle that corresponds to the predefined vehicle will respond to the receipt of the request transmitted by the wireless communication network to perform the predefined action. Vehicles that do not perform the predefined action under these conditions certainly do not match the predefined vehicle.
    The request consists, for example, according to one embodiment, in a characteristic identifying the predefined vehicle. Thus, the vehicles that receive this request via the wireless communication network will know that this request is not intended for them, but that it is intended for another vehicle, namely the predefined vehicle.
    The feature includes, for example, the license plate of the vehicle and / or a chassis number of the vehicle and / or the name of the vehicle owner. The characteristic is, for example, stored in an internal memory of the vehicle.
    According to one development, the wireless communication network is a WLAN communication network or a mobile telephone communication network.
    According to another development, the communication network is a network according to the "LoRa" standard. The "LoRa" network is a wide range and low power communication network. The wireless communication network thus comprises, according to one embodiment, a LoRa communication network.
    According to one development, the communication is or will be encrypted by the wireless communication network.
    A car park within the meaning of the present invention is a parking surface used for parking several vehicles (in the case of parking on private land) or parking space (in the case of parking on public land ). Parking spaces are generally referred to under this term for the purpose of simplification. According to a development, the car park is a building of car parks or a parking lot.
    According to another development, after transmission, the parking location is monitored by one or more environmental sensors to determine the surrounding field data corresponding to the monitoring and verification will be done according to the surrounding field data transmitted.
    This results in particular the technical advantage of performing the verification effectively. Verification from the surrounding field transmitted data means that this data is continuously analyzed to determine whether, using one or more of the surrounding field sensors, the area or zones being monitored contain a vehicle that is performing the field. predefined action. For example, a surrounding field sensor is a video sensor so that the surrounding field data corresponds to the video data. In this embodiment, the verification includes, in the image analysis of the video data to check if the area monitored by the video sensor has a vehicle that performs the predefined action. One or more environmental sensors are surrounding field sensors such as: radar sensor, video sensor, laser sensor, lidar sensor, ultrasonic sensor, infrared sensor and magnetic sensor. The different sensors are identical or different.
    According to a development, the predefined action consists in selecting an element in the group of constituted elements such as: activating one or more lighting elements of the vehicle, in particular a headlamp and / or a fog lamp and / or lighting of vehicle lighting brake and / or direction indicator, activate a wiper blade, such as that of a certain front wiper, activate a horn, open a vehicle door, open a window of the vehicle, start the vehicle engine by accelerating as an option, the transmission being disengaged. Optional means that the acceleration of the disengaged transmission line is optional. The acceleration, the transmission line being disengaged, consists, for example, in setting itself to a minimum, predefined rotational speed.
    Activating one or more elements of the vehicle lighting has in particular the technical advantage that this activation of the lighting elements of the vehicle is particularly simple and effective to recognize. This allows a very effective verification.
    Activating the windshield wiper has the technical advantage that it is possible to recognize the movement of the wiper in a particularly simple manner with a surrounding field sensor. This is indeed for the wiper, a mobile object that is detected or recognized very simply in the video data.
    In particular, activating the buzzer has the technical advantage that the action can be detected and recognized very simply. This is particularly the case if the parking space is monitored using one or more microphones to determine the acoustic data corresponding to the monitoring, which is also provided by the invention.
    In particular, starting the vehicle engine by accelerating the option, the transmission line being disengaged, has the technical advantage of being a particularly effective action to detect. This can especially be done using a microphone, as provided in one embodiment. In particular, when the vehicle accelerates when the transmission line is disengaged, this results in a particularly high noise level compared to the case of the vehicle whose engine runs only empty, which can detect in a very effective manner , the predefined vehicle among the other vehicles, only thanks to its low speed of movement in the car park.
    According to another development, the request is to repeat the action one or more times among predefined vehicles.
    This results in particular the technical advantage of an effective verification because it can, for example, scan the environment data after repeated signals or patterns, so that by recognizing the repeated signals of the vehicle, and which has actually repeated the predefined action one or more times so that environmental data concerning the repeated signals and / or repeated patterns will be scanned.
    In particular, it results in the technical advantage of being able to distinguish a vehicle from other vehicles, even if the illumination of the vehicle repeated once, is activated even if the vehicle has performed this operation only only once by a start and stop.
    According to one development, the vehicle location device is designed or constructed to execute the vehicle location method.
    According to another development, the invention also relates to a method of locating a vehicle by the locating device as defined above.
    drawings
    The present invention will be described below, in more detail with the aid of examples of embodiment of a method and a device for locating a vehicle in a parking lot, shown in the accompanying drawings in which: Figure 1 shows very schematically the flowchart of a vehicle location method, Figure 2 shows a vehicle location device, and Figure 3 shows a parking space for vehicles.
    Description of embodiments
    Figure 1 shows a very simplified flow chart of a method of locating a motor vehicle.
    The method includes: transmitting a request through a wireless communication network in the car park 301 to a predefined motor vehicle 309 to request that vehicle 309 to perform a predefined action, after the issuance of the request, check 103 whether a vehicle in parking 301 has executed or is executing the predefined action, if the check shows that the vehicle in parking lot 301 has executed or will execute the predefined action, authenticate 105 the vehicle as the predefined vehicle 309 and locate 107 this predefined vehicle at its instantaneous position.
    According to a development, the location consists of locating the predefined vehicle on the digital map of the car park.
    Since in step 103 it is found that there is no vehicle in the car park that has executed the predefined action or is in the process of executing it, then, according to one embodiment, it is planned to restart the process by step 101. This allows, for example, to have the technical advantage that possible circumstances at the first pass did not allow to authenticate or locate the vehicle, although the predefined vehicle was in the parking lot, while on the second pass, these fortuitous circumstances did not recur, which makes it possible to locate and authenticate the vehicle in the car park.
    According to a not shown embodiment, the method restarts after step 103 if the verification has shown that no vehicle in the car park has performed the predefined action or is about to execute it.
    According to one development, the parking lot is monitored according to step 101 using one or more surrounding field sensors to determine the data corresponding to the monitoring of the surrounding field and the verification according to step 103 is carried out. relying on the surrounding field data thus obtained. For example, it is expected that the surrounding field sensor (s) monitor one or more parts of the parking lot. Such a part is, for example, the entrance or the exit of the car park. In particular, such a part is the removal station, where the vehicle is left to perform the automatic valet maneuver.
    A parking maneuver or automatic valet, also called AVP maneuver, is an automatic vehicle storage maneuver.
    Performing such an automatic storage maneuver includes driving the vehicle automatically from the removal station to its parking position in the parking. This operation is done without driver, that is to say without the driver is necessarily in the vehicle. The vehicle is driven without a driver. Driverless driving consists, for example, in remotely controlling the vehicle or in driving the vehicle autonomously.
    An automatic parking maneuver consists, for example, in driving the vehicle from its storage position to its recovery position by automatic guidance. This is done in a similar way to automatic driving between the removal station and the driverless parking space. This is done in particular by the remote control of the vehicle or by its circulation in autonomous mode.
    Thus, according to one embodiment, the predefined vehicle is an AVP vehicle. An AVP vehicle is a vehicle designed to perform an automatic parking maneuver. An AVP vehicle is particularly a vehicle that can be remote controlled and / or can travel in autonomous mode.
    Figure 2 shows a device 201 for locating a vehicle.
    The device 201 comprises: a communication interface 203 for sending a request by a wireless communication network made in the parking 301 to a predefined vehicle 309 for this vehicle 309 to perform a predefined action, a verification facility 205 for check after issuing the request, if a vehicle in the car park 301 has executed or is about to execute the predefined action, an authentication facility 207 to authenticate the vehicle as a predefined vehicle 309 that executes or performed the predefined action and a location facility 209 to locate the predefined vehicle 309 at its instantaneous position.
    According to one embodiment, the device 201 comprises one or more surrounding field sensors for monitoring the parking.
    According to one development, the communication interface 203 receives the surrounding field data from one or more surrounding field sensors. The connection is made, for example, by the wireless communication network. This is done in addition to a wired communication network. The communication interface 203 is designed according to an embodiment so that with the wireless communication network, one or more wireless communication networks (x) can (nt) communicate.
    Figure 3 shows a parking lot 301 for vehicles.
    The car park 301 includes the device 201 of FIG.
    Parking 301 has a drop-off station 303 where the vehicle will be removed for an automatic parking maneuver. This means that the automatic storage or parking operation begins at the dispense station 303.
    Parking 301 has several parking spaces 305 for storing vehicles. An automatic parking operation is to automatically drive a vehicle from its removal position 303 to its parking position 305 to store it there.
    A vehicle 307 was left at station 303. But this vehicle does not allow to perform an AVP maneuver.
    On one of the parking spaces 305 there is a parked vehicle 309. This vehicle is intended to perform an automatic parking maneuver. However, the vehicle 309 must not park at the parking location where it is at the given time. But, since the vehicle 307 is blocked in the removal station 303, the driver of the vehicle 309 stored his vehicle at the parking space 305.
    In the case of the automatic parking maneuver, it must generally be assumed that the vehicle that is to perform the AVP maneuver is in the dispense station 303, that is, at the 303. Indeed, the trajectories that the AVP vehicle must travel are usually calculated to start at this dispense position 303.
    Insofar as the vehicle which is not at the dispatcher station 303 but will be driven as if it were actually at the dispatcher station 303 significantly increases the risk of accident in relation to the situation in which the vehicle AVP starts correctly at from the dispense position 303.
    It is necessary to locate the vehicle AVP 309 in the parking 301. Because then, depending on the location we can recalculate the trajectory that the vehicle 309 must go. In particular, it will be possible to select, for example, a new storage position for the vehicle 309.
    According to the invention, it is intended to send a request to the vehicle 309 via the wireless communication network developed in the car park 301. This request consists in asking the vehicle 309 to perform a predefined action.
    This request can then be, for example, received by the motor vehicle 307. But, since this request is not intended for the vehicle 307, it will not execute the predefined action. On the other hand, upon receipt of the request, the vehicle 309 knows that this request is intended for it and will execute it according to the receipt of the request.
    The car park 301 is monitored by a set of sensors composed of one or more environmental sensors, so that based on the monitoring it will be possible to determine whether a vehicle is in the car park 301 which has executed or is to execute the car. predefined action. Thus, the vehicle 309 can be distinguished from all of the two vehicles 307, 309 as the vehicle that is to perform the AVP operation. Accordingly, it can be seen that the vehicle 309 is precisely not at the removal station 303. Correspondingly, the operation AVP is adapted, for example, according to the instantaneous position of the vehicle 309 at the storage position. 305. The predefined action consists, for example, in activating a projector. This means that the vehicle 309 is instructed to control a projector for illumination. In particular, this action can be easily observed by one or more cameras of a surveillance infrastructure of the parking space. This means that it is checked whether the headlamps belong to the vehicle whose parking management system, assumes that it is the AVP vehicle.
    According to another development, the predefined action is to activate a flashing light, that is to say a traffic direction indicator.
    According to another development, the predefined action is to activate a brake light. This allows in particular to have the technical advantage that this action can be detected even at the rear of the vehicle towards the environment sensor, for example, using a camera.
    According to another development, communication is provided between several predefined actions. Such communication consists, for example, in activating a flashing light, a searchlight and a brake light.
    According to another development, the request consists of requesting the repetition one or more times of the action predefined by the predefined vehicle. This means that the action consists, for example, in a sequence. Such a sequence consists, for example, in connecting and / or disconnecting one or more elements of a vehicle lighting and / or a brake light and / or a traffic direction indicator and / or a windshield wiper and / or an audible warning device and / or the repeated opening and closing of a vehicle door and / or the repeated opening and closing of a vehicle window and / or the repeated starting and shutdown of the optional vehicle engine with acceleration when the transmission is disengaged.
    An important advantage is, in particular that the concept of the invention allows a redundant and confirmed location with authentication of the vehicle.
