    Finally, the invention relates to a vehicle, a parking management system and a computer program.
    State of the art
    Document DE 10 2013 222 071 A1 describes a parking management system. The parking management system sends, for example to the vehicle, position data of a parking space allocated to a vehicle by a communication network.
    DE 10 2012 222 562 A1 discloses a managed parking surface system for transferring a vehicle from a starting position to a destination position.
    Purpose of the invention
    The present invention aims to develop an effective communication concept between a parking management system and a driverless vehicle in the parking lot.
    DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the invention is a method of communication between a parking management system and a vehicle traveling without a driver in the car park, according to which the car park comprises a plurality of base stations distributed throughout the car park. space, and depending on the instantaneous position of the vehicle in the parking lot and a digital map of the parking with the position of several base stations, a base station is selected from among all the base stations, to which the vehicle connected at this time to one of the base stations will then be connected to communicate with the parking management system.
    According to another development, the invention relates to a communication device between a parking management system and a driverless vehicle traveling in the parking lot, the car park equipped with several base stations distributed in the space, device characterized in that it comprises a memory containing the digital map of the car park, this digital map containing the positions of the different base stations, a processor which according to the instantaneous position of the vehicle in the parking lot and the digital map of the car park , selects a base station from among all the base stations to which the vehicle is to switch from the base station to which the vehicle is connected at that time, to then connect to that selected base station, and communicate with the parking management system.
    According to another development, the invention relates to a vehicle equipped with a device as defined above or a parking management system with a device as described.
    According to another development, the subject of the invention is a computer program with a program code for implementing the method described above when the program is applied by a computer.
    Finally, the invention relates to a vehicle parking with such a management system. The invention is based on the fact that the above problem could be solved in that the base station to which the vehicle is to switch to subsequently communicate with the parking management system by this base station is selected at the times according to the instantaneous position of the vehicle in the parking lot and the digital map of the car park which includes the position of several base stations. This means in particular that one avoids a long scan to find available base stations. Thus, advantageously, one predefines for the vehicle the base station to which it must then switch. The invention is based in particular on the knowledge of the location of the base stations in the parking lot as well as on the application of knowledge of the instantaneous position of the vehicle in the car park to select a base station among all the stations. to which the vehicle could then switch.
    Thus, there is in particular the technical advantage of an effective communication concept between a parking management system and a driverless vehicle in the parking lot.
    The connection in the sense of the present invention is in particular a communication link. This means that a communication link is established between the parking management system and the vehicle. To form this communication link, the base stations of the car park are used. During traffic in the car park, the vehicle will use several base stations because, in general, a base station does not cover the entire car park.
    In a communication network extending over the car park there are thus several base stations. Usually, the user, here the vehicle, sweeps during the first establishment of the connection with the communication network, all the base stations that it can receive and usually clings to the base station corresponding to the best reception .
    If now the vehicle is traveling in the car park, from a certain point, it will arrive in an area in which the vehicle may receive the base station to which it was originally connected. This can result in the interruption of the communication link with the parking management system or the stall. Then, when the reception is completely cut off, the user, here the vehicle, will look for a base station offering better reception and then clings to the station found.
    In this known procedure, it can happen that the bad reception conditions last for a certain time, in particular before the switching of the base station so that as long as the vehicle is scanning for new stations, generally no reception is not possible. Such a procedure can result in a high latency and a reduced data rate, which is insufficient, for example for an AVP application.
    However, in the case of the application AVP ("Automatic Parking Valet"), it requires a stable communication link between the vehicle and the parking management system with a latency as low as possible. Such a communication link is used, for example, so that the parking management system can send the vehicle the data of the position of the location assigned to the vehicle. For example, a communication link is used to allow the parking management system to send remote control commands to the vehicle to remotely control the vehicle in the parking lot. For example, using such a communication link to send the vehicle a digital map of the parking lot by the management system so that the vehicle based on this digital map can drive without driver independently in the parking.
    As according to the invention, the following base station is selected for the vehicle, the latter will no longer have to scan for a long time to find the base stations that it can receive.
    A car park within the meaning of the present invention is a parking surface for vehicles. The parking thus constitutes a coherent surface with several parking spaces (in the case of parking on private land) or parking spaces in the case of public parking. The parking, according to one embodiment, is a parking lot. But, according to another embodiment, the parking can also be a garage.
    According to one development, the communication network comprises a WLAN network and / or a mobile telephone network.
    A base station within the meaning of the invention is thus, for example, a WLAN base station.
    A base station within the meaning of the invention is, for example, a mobile phone station. A base station according to the invention is also, for example, a WLAN access point.
    According to one embodiment, the switching command requesting the vehicle to switch from the instantaneous base station to the selected base station is sent to the vehicle by a communication network.
    This results in particular the technical advantage of effectively predefining the moment at which the vehicle must change base station. This gives the preset change order applied to the vehicle to change the base station. The instant of the change corresponds here practically to the moment of the reception of the change order on the side of the vehicle increased by the latency, for example that of the WLAN communication network which is in a range of a few milliseconds going up to at 100 ms.
    According to a development, the change order contains the moment at which the vehicle must change base station. Thus, there is, for example, the technical advantage of predefining effectively for the vehicle the moment at which it must change base station. This moment can also be called the future moment when the vehicle changes from base station. The order of change includes, for example, that of a location in the parking lot, where the vehicle must change base station. This translates, for example, in the technical advantage of effectively predefining the place where the vehicle must change base station.
    According to one embodiment, the vehicle changes base station according to the receipt of the change order.
    Insofar as the order of change comprises the moment at which the vehicle must change base station, it is thus provided, according to one embodiment, that the vehicle responding to the receipt of such an order, changes station basic at the predefined time.
    Insofar as the change order contains the place where the vehicle must change base station, according to one embodiment, it is expected that depending on the receipt of such a change order, the vehicle changes. base station when it is there. The location of the base station, within the meaning of the present invention, refers to the change of the vehicle from the instantaneous base station to the selected base station.
    According to one embodiment, the selection is made according to the destination position in the parking to which the vehicle must go. Thus, there is especially the technical advantage that the selection can be done effectively. In fact, depending on the destination of the vehicle, the selection does not have to take into account base stations located beyond the radio range of the destination position.
    The destination position is, for example, the final position of the set path that the vehicle must travel. This means in particular that the set path is subdivided into several path segments each having a final position. Thus, the vehicle moves from one end position of a partial segment to the next final position of another path segment until it has completely traveled the set path.
    The destination position is, for example, the end position of the target path.
    The setpoint path ends at the parking position (parking slot) of the parking lot where the vehicle is to be stowed. The set path ends, for example, at the parking resumption location, where the driver can retrieve the vehicle.
    According to another embodiment, the selection is made according to the set trajectory that the vehicle must travel.
    Thus, one has, in particular, the technical advantage of effectively performing this selection. In particular, it is no longer necessary to consider the base station in the selection that may be outside the radio range of the set path. The set trajectory that the vehicle must travel means here the target trajectory that remains to be traveled by the vehicle, that is to say the target trajectory upstream of the vehicle according to its direction of travel.
    According to one embodiment, the selection is based on the instantaneous speed of the vehicle. This results in particular the technical advantage that the selection is done effectively. In fact, it is possible, for example, to predefine a base station for the vehicle which is farther from the vehicle than the base station corresponding to the instantaneous position of the vehicle. Indeed, taking into account the speed of the vehicle, it can arrive quickly to this base station. If in this application example the nearest base station was predefined to the vehicle, it would nevertheless be necessary, because of the speed of movement of the vehicle, to provide for a change to another, more remote base station, i.e. say that there would be an additional change of the base station. Since a base station change usually consists of disconnecting from the instant base station and signaling itself to the selected base station, deleting a base station saves time effectively by suppressing an operation of the base station. registration (announcement).
    According to one embodiment, the digital map includes areas around the base stations that have different reception conditions in terms of latency and / or data rate, so that the selection will be based on these different reception conditions.
    This results in particular the technical advantage that the selection will be effective. Nevertheless, the selection of an appropriate base station advantageously allows to have, always at least a minimum data rate and / or maximum latency.
    The selection is made, for example, not to exceed a minimum data rate, predefined. For example, it is intended to perform the selection so as not to exceed a fixed maximum latency.
    According to another development, the selection is made according to what vehicle must always have a line of sight link with one of the base stations.
    This results in particular the technical advantage of a robust communication link with the parking management system or the maintenance of such a link. Indeed, usually, a direct line connection between the vehicle and the base station corresponds to an uninterrupted communication link. Indeed, a direct line connection assumes that there is no object such as a column or a wall that stops the radio signals.
    According to a development, the communication device between the parking management system or a parking space and a vehicle traveling without a driver in the car park applies the communication method between the parking management system and a driverless vehicle in the car park. .
    According to one development, the vehicle executes the method as described above and the parking management system applies the method described above.
    According to one embodiment, there is provided a communication interface for communicating over a communication network. According to one embodiment, the different base stations distributed in space establish a wireless communication network.

    According to one embodiment, the device comprises the communication interface described above.
    According to one embodiment, the vehicle comprises the communication interface described above.
    According to one embodiment, the parking management system comprises the communication interface described above.
    The technical functionalities of the method are analogous to the technical functionalities of the device and vice versa. This means in particular that the characteristics of the process derive from the characteristics of the device and vice versa.
    According to one embodiment, the communication interface transmits a switching command requesting the vehicle to switch from the instantaneous base station to the selected base station, this command being transmitted to the vehicle by a communication network.
    According to one embodiment, the processor selects, depending on the destination position in the car park, where the vehicle must go.

    According to one embodiment, one or more process steps or all process steps are performed by the vehicle.
    According to one embodiment, a step of the method or several steps of the method or all the steps of the method apply the parking management system.
    According to one embodiment, the instantaneous position of the vehicle in the parking lot is determined. The determination of the instantaneous position of the vehicle consists, for example, in that the vehicle itself determines its instantaneous position. The vehicle sends, for example, the position it has itself determined by the communication network to the parking management system or to the device. The determination of the instantaneous position of the vehicle consists, for example, in monitoring the vehicle with the parking monitoring system during its driverless driving in the car park.
    Such a monitoring system comprises, according to one embodiment, one or more environmental sensors. An environmental sensor is, for example, one of the following environmental sensors: video sensor, radar sensor, ultrasonic sensor, li-dar sensor, laser sensor, infrared sensor and magnetic sensor. The surveillance system comprises, for example, one or more video cameras. The monitoring system comprises, for example, one or more light barriers and / or one or more door opening sensors.
    The monitoring system thus makes it possible to monitor the traffic of the driverless vehicle in the car park. Thus, thanks to the monitoring system, we know the instantaneous position of the vehicle. The monitoring system tracks or monitors the driverless vehicle and, based on this monitoring or tracking, determines the vehicle's instantaneous parking position.

    Description of embodiments
    Figure 1 shows very schematically a flow chart of a communication process between a parking management system and a driverless vehicle in the parking lot.
    The car park has several base stations distributed in the space. The base stations form a wireless communication network. The wireless communication network can thus communicate with the parking management system. This means in particular that during its driverless driving in the parking lot, the vehicle communicates via the wireless communication network with the parking management system.
    According to the step 101, depending on the instantaneous position of the vehicle in the car park and the digital map of the car park which includes the positions of several base stations, it will be possible to select a base station among several base stations, with which the vehicle must then communicate from the instant base station among all the base stations. It can be connected to the selected base station to communicate with the parking management system.
    According to a development, the vehicle changes from the instant base station to the selected base station to be connected to that selected base station. According to one embodiment, after the change, the vehicle clings to the selected base station.
    According to a development, the selection is made in the vehicle. According to one embodiment, the selection is made in the parking management system.
    According to one embodiment, the parking management system must send a change command indicating to the vehicle that it must change from the instantaneous base station to the selected base station, this order being transmitted to the vehicle by the communication network. wireless.
    Figure 2 shows the flow chart of another communication method between the parking management system and a driverless vehicle in the parking lot, the car park having a plurality of base stations distributed in the space.
    The different distributed base stations establish a wireless communication network. This means that the car park will have a wireless communication network built with the different base stations.
    In step 201, the instantaneous position of the vehicle in the parking lot is determined. For example, it is provided that the vehicle itself determines its instantaneous position and sends it via the wireless communication network to the parking management system. For example, it is intended to determine the instantaneous position of the vehicle based on the monitoring system as described above.
    According to step 203, depending on the instantaneous position of the vehicle in the parking lot and the digital map of the car park comprising the position of the different base stations, a base station is selected from among all the base stations to which the the vehicle must then switch to switch from the instantaneous base station among all the base stations to which the vehicle is connected at that time, through this communication to connect to the selected base station and communicate with the management system of the base station. car park.
    According to one embodiment, the digital parking card which includes the position of the different base stations is sent by the parking management system to the vehicle by a wireless communication network. Thus, advantageously, the digital map is available in the vehicle via the method.
    FIG. 3 shows a device 301 for communication between a parking management system and a vehicle traveling without a driver in the parking lot; the car park has several base stations distributed in the space.
    The device 301 comprises: a memory 303 in which the digital map 305 of the car park is recorded, this digital map containing the position of the different base stations, a processor 307 which, depending on the instantaneous position of the vehicle in the parking and of the digital map of the car park, selects from among several base stations, a station to which the vehicle must switch from its instantaneous base station, among all the base stations, to be connected to the selected base station and ability to communicate with the parking management system.
    According to one embodiment, the device 301 has a communication interface for communicating over the wireless communication network.
    FIG. 4 shows a vehicle 401. The vehicle 401 is equipped with the device 301 of FIG.
    According to one embodiment, the vehicle comprises a communication interface for communicating via a wireless communication network, especially with a parking lot by its management system.
    According to one embodiment, the vehicle 401 runs independently without driver in the parking.
    According to one embodiment, the vehicle is driven without driver, by remote control in the parking. This also means that the vehicle 401 is remote controlled. For example, it is expected that the management system parking remote control the vehicle.
    This means in particular that the vehicle 401 is made to move without driver in the parking lot. This means in particular that a driverless vehicle within the meaning of the present invention consists, for example, to circulate remotely and / or autonomously.
    Figure 5 shows a parking management system 501.
    The parking management system 501 comprises the device 301 of FIG.
    According to one development, the parking management system 501 comprises a communication interface for communicating via a wireless communication network, in particular with the vehicle that travels without a driver in the car park.
    According to one embodiment, the parking control system 501 remote control the vehicle in the parking lot.
    Figure 6 shows a detail of a car park 601 presented in a simplified form.
    Parking 601 includes a taxiway 603. Parking 601 further includes a first base station 605 and a second base station 607. The two base stations 605, 607 are distributed in the parking space 601. It is for example, that the two base stations 605, 607 are installed on the ceiling above the taxiway 603.
    According to the drawing, the two base stations 605, 607 are represented by a cross on the taxiway 603, but, for those skilled in the art, it is clear that it is only a symbolic representation. The two base stations 605, 607 may be installed as described above, for example, on the ceiling or on infrastructure elements of the car park 601. Such infrastructure elements are, for example, columns or walls or partitions. .
    A first zone 609 fixes the first base station 605; this zone is represented symbolically in broken lines by an oval line.
    A communication link is possible with the first base station 605 in the first area 609; this communication link corresponds, for example, to a predefined minimum data rate or to a predefined maximum latency.
    The more the user, here the vehicle, moves away from the first base station 605 and more, in general, its reception will be bad. Thus, a second zone 611 is established around the first base station 605. This second zone is represented by two dashed curves that join the first zone 609.
    Due to the greater distance in the second zone 611, there will be a reduced data rate or a higher latency compared to the first zone 609.
    Similarly to the first base station 605, a first area 613 is also fixed around the second base station 607, which corresponds to the first area 609 of the first base station 605.
    Similarly, a second area 615 is established around the second base station 607 which corresponds to the second area 611 of the first base station 605.
    The two areas 613, 615 of the second base station 607 are shown in the drawing as the areas 609, 611 of the first base station 605. The explanations given above make it possible to avoid repetitions.
    A vehicle 616 is traveling on the track 603. The direction of circulation of the vehicle 616 is indicated symbolically by an arrow bearing the reference 619.
    This also means that the vehicle 616 is traveling from the first base station 605 to the second base station 607. In FIG. 6, the vehicle 616 is shown at two successive times. Reference 617 relates to the vehicle 616 which flows without a driver at the first instant on the track 603 in the traffic direction 619.
    The reference 619 indicates that at a second instant after the first instant, the vehicle 616 circulates in the direction of circulation 619 without driver on the taxiway or roadway 603.
    During its circulation on the track 603 in the direction 619, the vehicle travels in the first zone 609 of the first base station 605. The reception is good. The vehicle 616 clings to the first base station 605 to communicate through this link with the parking management system not shown here.
    As the vehicle 616 moves in the traffic direction 619, it leaves the first area 609 and arrives in the second area 611 as schematized by way of example for the second point.
    The reception deteriorates, that is to say that the communication link with the first base station 605 becomes bad. Only then will the 616 vehicle switch to another base station for better reception.
    It is intended to install the two base stations 605, 607 so that their respective first areas 609, 613 overlap. If then the vehicle 616 is in this overlap zone, it can communicate optimally with both the first base station 605 and the second base station 607. According to the invention, the vehicle 616 is provided. switching from the first base station 605 to the second base station 607 precisely when the vehicle 616 is in the overlap area. Schematically, in FIG. 6, the vehicle 616 has thus been represented at the first moment, symbolically under the reference 617 on the channel 603.
    This ensures that the vehicle 616 can establish an optimal communication link with one of the base stations distributed in the space inside the car park 601.
    To determine now when and / or the vehicle 616 can switch from the first base station 605 to the second base station 607, there is provided, according to the invention, a digital map of the parking lot 601; this digital map contains the position of the base stations, that is to say in particular the positions of the first base station 605 and the second base station 607. The digital map also includes the zones 609, 611, 613, 615 of the two base stations 605, 607 which, as described above, have different reception conditions from the point of view of latency and / or data rate.
    In addition, it is intended to determine the instantaneous position of the vehicle 616 in the car park 601. Knowing that the vehicle is in the car park 601; knowing the base stations in the parking lot 601 and the reception conditions in the environment of the base stations, it is thus possible to advantageously determine the moment at which the vehicle 616 must switch from the first base station 605 to the second base station. In particular, taking this into account, the second base station 607 can be selected as the base station to which the vehicle 616 is to communicate.
    For example, it is intended to send a switching command as described above by the wireless communication network, i.e. here by the first base station 605 to the vehicle 616 for receiving this change order, the vehicle switches from the first base station 605 to the second base station 607 to be connected thereto and communicate through this communication link with the parking management system.
    Figure 7 shows another area of parking 601. The same references as in Figure 6 will be used to designate the same elements.
    Figure 7 shows the area in which the vehicle 616 is to rotate around a corner. The two base stations 605, 607 are installed so as not to have a direct visual link between the two base stations 605, 607. As soon as the vehicle 616 turns around the corner, that is to say passes from the first station of base 605 towards the second base 607 in the direction 619, the vehicle 616 receives a change order to change from the first base station 605 to the second base station 607. The second base station 607 is certainly further from the base station 607. vehicle 616 as the first base station 605, which could lead, if necessary, to less good reception. But, thanks to this procedure, it is advantageously avoided that the communication link between the vehicle 616 and the first base station 605 does not completely cut. This could happen if the vehicle 616 was at the second moment indicated symbolically by the reference 619 on the roadway 603, that is to say if it had already bypassed the corner, because then the concrete walls 707 between the vehicle 616 and the first base station 605 are involved. Thus, there is no line of sight link between the vehicle 616 and the first base station 605. This is represented schematically by a broken line 705. This line is interrupted because of the absence of visibility link between the two 707 concrete walls.
    But as in the first instant shown schematically by the reference 617 the first vehicle 616 is informed to change base station; this ensures that there is always a visibility link between the vehicle 616 and one of the base stations 605, 607. This also means that the vehicle 616 has been informed at the corner that it has to change its station. based. In the position corresponding to the first instant, indicated symbolically by the reference 617, there is a visual connection 701 between the vehicle 616 and the first base station 605. In this position there is also a visual connection 703 between the vehicle 616 and the second base station 607. Even when the vehicle 616 is in the position corresponding to the second instant symbolically represented by the reference 619, there is a line of sight line between the vehicle 616 and the second base station 607. visual link is also represented by the broken line with the reference 709.
    According to this embodiment, the switching command is sent to the vehicle by the wireless communication network when it is in a position corresponding to the first instant so that there is always a direct, direct connection with base stations 605, 607.
    The car park 601 comprises other base stations not shown in FIGS. 6 and 7 which are distributed in the parking lot 601. As described above, the second base station 607 is the base station to which the vehicle 616 must change at the time. from the first base station 605 to be connected thereto and to communicate with the parking management system.
    The selection was made according to the instantaneous position of the vehicle 616 in the parking lot 601. In particular, this selection was made according to the traffic direction 619 of the vehicle 616.
    In summary, there is an effective concept that according to its instantaneous position in the parking and the digital map, that is to say according to the information stored to position the base stations, the vehicle can switch between base stations and always remains in an area with good reception. Good reception means that the communication link between the vehicle and the base station has at least a predefined minimum data rate and / or that the latency is limited by a maximum.
    It is planned to select the base station to which the vehicle is to switch in the car park on the condition, for example, that there is always a direct line connection between the vehicle, that is to say in particular between the vehicle antenna and the base station.
    The visual connection in the sense of the present invention is in particular a connection between a communication interface, in particular a vehicle antenna and a base station. The advantages according to the invention reside in particular in that one avoids a long scan to find available base stations. This means that sweeping is avoided to find available base stations.
    In particular, an advantage of the invention is to allow the changeover to another base station before the quality of the link (latency and data rate) deteriorates and there is no longer a communication link reliable with the base station.
    Another advantage is that one only switches to the base stations which remain visible on the rest of the vehicle journey. This avoids unnecessary changes. This means that, for example, it changes only to a base station that can still be received by the vehicle traveling on the set path.
    In particular, the distribution and the number of base stations in the car park can be optimally optimized.
    The management, ie the knowledge of the position of the base stations and the initialization of a change of base station can be done, for example, with the parking management system or directly with the vehicle.
    According to another development, three zones are fixed around a base station. Then, an area is fixed relative to the base station in which the reception is good so that the latency and data rate are good. This zone corresponds, for example, to the first zones 609, 613.
    Adjacent, there is an area in which reception is poor, latency is greater, and data rate is lower. This corresponds, for example, to zones 611, 615.
    Then, further away from the base station, there is a third zone in which the base station is badly received, so that the communication link is cut off. This area is not shown in the figures.
    According to a development, the concept of AVP function according to the invention is applied, which means that, for example, in an AVP driving system that can be part of the parking management system, there is the digital map as it has been described above. This digital map contains in the different areas of the car park, base stations that are well received and can be used for the respective area. As in the AVP driving system it is also known where the vehicle is instantaneously and where it moves, this AVP driving system can ask the vehicle to switch base station determined as soon as it leaves the area of good reception of the current base station. This change can be done very quickly because it does not take any scanning to find the base stations by the vehicle. This optimizes latency and data throughput and has a reliable application system.
    Another advantage is that thanks to the robust communication link, there is efficient operation of the vehicle, which notably ensures this advantage for the parking.
