JP-A-2014-014938

  The prior art parking lot navigation system has at least the following three problems.

1) Handling of a car that does not follow the distributed guidance information The conventional parking navigation system generates (updates) guidance information according to the current vacancy status, but the driver always follows the guidance information. is not. There is a possibility that the driver ignores the guidance information and goes to a vehicle compartment that is convenient for the driver. The conventional parking lot navigation system transmits guidance information and the like without discriminating such vehicles, so that the guidance information that should have been provided to the succeeding vehicle is allocated to the preceding vehicle. There is a possibility that waste caused by ignoring the information by the preceding vehicle may occur.

2) Waiting for vacancy in the cabin, blocking the lane due to a car that is struggling to enter the garage, etc. If the driver tries to park in a car that is convenient for the driver, The driver may temporarily stop the car on a nearby road and wait on the spot until the cabin becomes empty. In this case, depending on the position of the stop, traffic and parking may be hindered.Therefore, guide the following vehicle to the route where the preceding vehicle is paused, If the driver is instructed to park in the passenger compartment, the vehicle may get stuck. In addition, there is a case where, for example, a beginner of driving struggles to enter a garage, and repeatedly performs switching on a lane, without being limited to waiting for a vacant room. Also in this case, there is a possibility that the following vehicle will pass or the parking operation will be hindered. In addition, there is a case where the lane is cut off due to an accident, and a case where something drops from the bed of a truck or the like to block the lane is also considered. Since the parking lot navigation system of the related art generates the guide information without taking this point into account, there is a possibility that the system may be stuck and the guide may be wasted.

3) Priorities for cars It is important to give priority to cars. For example, for a car that has already been parked (regardless of whether guidance has been followed), no further guidance information is required. Further, it is considered that no further guidance information is necessary for a vehicle that is temporarily stopped due to waiting for a vacancy or the like. Since the parking lot navigation system of the related art does not take such fact into account, the guide information is transmitted to a car that has already been parked or a car that has been temporarily stopped, which may cause waste.

  Therefore, an object of the present invention is to provide a server device that can transmit information for navigating in a parking lot to a car flexibly and efficiently according to the situation in the parking lot.

  The server device of the present invention is a server device that communicates with an automobile, a room sensor installed in each compartment in a parking lot, and a roadway sensor installed in each lane in a parking lot, A receiving unit, a road information receiving unit, an automobile information receiving unit, a priority generating unit, an allocation information generating unit, and an allocation information transmitting unit are included.

  The full / vacancy information receiving unit receives a sensor ID from the vehicle interior sensor and full / vacancy information including information on whether the vehicle is full or empty. The roadway information receiving unit receives a sensor ID from the roadway sensor and roadway information including information on whether or not the roadway is shielded. The vehicle information receiving unit receives, from the vehicle, vehicle ID, and vehicle information that is information including a status including information indicating whether the vehicle is running. The priority generation unit generates a priority for the vehicle ID based on the status. The allocation information generation unit allocates the vehicle rooms that are vacant and have no shielding in the corresponding vehicle path in order from the vehicle ID having the highest priority, and generates allocation information that is information on the allocated vehicle room. The assignment information transmitting unit transmits the assignment information to the corresponding vehicle.

  ADVANTAGE OF THE INVENTION According to the server apparatus of this invention, the information for navigation in a parking lot flexibly and efficiently according to the situation in a parking lot can be transmitted to a motor vehicle.

  Hereinafter, a case in which the following vehicle is stranded due to the behavior of the preceding vehicle will be described with reference to FIGS. 1, 2, and 3.

<Case 1>
For example, as shown in FIG. 1, it is assumed that the car 2-1 has entered from the entrance of the parking lot. It is assumed that the car 2-1 has been subjected to navigation for guiding to the passenger compartment 9-P (the route indicated by the broken arrow in the figure). At this time, it is assumed that the driver of the car 2-1 finds that the vehicle compartment 9-Q near the elevator hall is vacant, ignores the navigation, and parks in the vehicle compartment 9-Q (see FIG. The route indicated by the solid arrow in the figure).

  On the other hand, it is assumed that the succeeding automobile 2-2 has undergone navigation for guiding to the passenger compartment 9-Q (indicated by a double circle in the figure). However, as described above, the passenger compartment 9-Q is already occupied by the preceding vehicle (car 2-1) that has not followed the navigation. Such a case corresponds to one of the cases where the following vehicle (automobile 2-2) is stuck.

<Case 2>
In addition, for example, as shown in FIG. 2, it is assumed that the car 2-1 has entered from the entrance of the parking lot, and the car 2-1 has been subjected to navigation for guiding to the vehicle compartment 9-P as in FIG. 1. (The route indicated by the dashed arrow in the figure). At this time, the driver of the car 2-1 wants to park in the car room 9-Q or the car room 9-R near the elevator hall, ignores the navigation, and waits for the corresponding car room to be available. It is assumed that the vehicle is temporarily stopped in front of the cabin 9-S (a route indicated by a solid arrow in the drawing).

  On the other hand, it is assumed that the succeeding automobile 2-2 has undergone navigation for guiding to the vacant compartment 9-S (indicated by ◎ in the figure). However, as described above, the passenger compartment 9-S is blocked by the preceding vehicle (car 2-1) that has not followed the navigation and cannot be used. Such a case corresponds to one of the cases where the following vehicle (automobile 2-2) is stuck.

<Case 3>
Further, for example, as shown in FIG. 3, it is assumed that the automobile 2-1 has been switched back several times in an attempt to park in the passenger compartment 9-S.

  On the other hand, it is assumed that the succeeding automobile 2-2 has undergone navigation for guiding to the passenger compartment 9-Q (indicated by a double circle in the figure). However, the roadway to the vehicle compartment 9-Q is blocked by the preceding vehicle (automobile 2-1) and cannot be used. Such a case corresponds to one of the cases where the following vehicle (automobile 2-2) is stuck.

<Change of navigation according to the situation>
It is a problem in the navigation in the parking lot that the following vehicle 2-2 often gets stuck as described above. However, if the navigation of the following vehicle 2-2 can be appropriately changed according to the situation, the above problem is solved. Can be solved. For example, as shown in FIG. 4, the succeeding automobile 2-2 has been subjected to navigation for guiding to the passenger compartment 9-Q (indicated by ◎ in FIG. 4). 2-2 assumes that the cabin 9-Q cannot be used. In this case, by changing the destination of the navigation for the car 2-2 to a vacant car room (for example, the car room 9-X in the figure, a circle mark) in which the corresponding lane has no obstruction, the above-mentioned stuck-up state is obtained. Can be eliminated.

  Hereinafter, an embodiment of the present invention that enables the navigation to be changed according to the situation will be described in detail. Note that components having the same functions are given the same reference numerals, and redundant description is omitted.

  Hereinafter, the configuration of the parking lot navigation system according to the first embodiment will be described with reference to FIG. As shown in FIG. 1, the parking lot navigation system 100 of the present embodiment includes a server device 1 managed by a parking lot management company and the like, and automobiles 2-1 to 2-K (K) entering the parking lot. ,..., 3-N (N is an arbitrary natural number) installed in each compartment in the parking lot, and a lane installed in each lane in the parking lot. , 4-M (M is an arbitrary natural number), the server device 1, the automobiles 2-1,..., 2-K, the cabin sensors 3-1,. .., 4-M are communicable via the network 8. The network 8 can be realized by any communication method. For example, the network 8 may be a wireless LAN.

  Hereinafter, the configuration of each device of the first embodiment will be described with reference to FIG. As shown in the figure, the server device 1 of the present embodiment includes an automobile information receiving unit 11, a priority order generating unit 12, an allocation information generating unit 13, an allocation information transmitting unit 14, a full / vacant information receiving unit 15, , A vehicle room DB 16, a road information receiving unit 17, and a road DB 18. Since the car information receiving unit 11, the assignment information transmitting unit 14, the full / vacant information receiving unit 15, and the roadway information receiving unit 17 are all components related to data communication, these are the components in the data communication unit 10. It may be. Similarly, the vehicle compartment DB 16 and the roadway DB 18 may be used as constituent elements in the storage unit 19.

  , 2-K include a status generation unit 21, a vehicle information transmission unit 22, an assignment information reception unit 23, and a navigation unit 24. , 3-N each include a vacancy detection unit 31 and a vacancy information transmission unit 32. Each of the roadway sensors 4-1,..., 4-M includes a roadway detection unit 41 and a roadway information transmission unit 42.

  Next, with reference to FIG. 7, the operation of the server device 1, the vehicle interior sensors 3-1,..., 3-N and the roadway sensors 4-1,.

  .., 3-N detect full / empty at any time (every predetermined time or whenever the detected state changes, or at both timings) (S31), and at any time, The sensor ID, which is the identification number of each of the sensors 3-1,..., 3-N, and full / vacancy information including information on whether the vehicle is full / vacant are transmitted to the server device 1 (S32). The full / vacancy information receiving unit 15 of the server device 1 receives the full / vacancy information (S15). The cabin DB16 stores the received vacancy information (S16).

  The roadway sensors 4-1,..., 4-M detect presence / absence of roadway shielding at any time (every predetermined time or whenever the detected state changes, or at both timings) (S41). At any time, the server apparatus 1 transmits the sensor ID, which is the identification number of the road sensor, and the road information including the information on the presence / absence of the shielding of the road to the server device 1 (S42). The roadway information receiving unit 17 of the server device 1 receives the roadway information (S17). The lane DB 18 stores the received lane information (S18).

  Next, with reference to FIG. 8, the operation of the server device 1 of this embodiment and the vehicles 2-1 to 2-K will be described. The status generation unit 21 of the automobiles 2-1,..., 2-K generates a status at any time (every predetermined time or whenever the status changes, or at both timings) (S21). The status may include information as to whether or not the corresponding automobiles 2-1,..., 2-K are running. Information indicating that the vehicle is in a parked state while the vehicle is stopped may be included. The automobile information transmitting unit 22 of the automobiles 2-1 to 2-K includes the automobile ID, the status, and the elapsed time since the corresponding automobiles 2-1 to 2-K entered the parking lot. The vehicle information, which is information, is transmitted (S22). The vehicle information receiving unit 11 of the server device 1 receives the vehicle information (S11). The vehicle information receiving unit 11 of the server device 1 may acquire the wireless LAN-ID of the transmission source together with the vehicle information. The acquired wireless LAN-ID can be used for estimating the position of the automobiles 2-1 to 2-K.

  The priority generation unit 12 generates a priority for the vehicle ID based on the status and the elapsed time (S12). For example, the priority generation unit 12 assigns a priority to the vehicles 2-1 to 2-K whose status (including any information of running / paused / parked) is “running”. May be generated. This naturally means that guidance is not required for the vehicles 2-1,..., 2-K whose status is “parking”, and that the vehicles 2-1, whose status is “paused”. , 2-K, it is considered that "waiting for idleness" mentioned in the above-mentioned case 2 or "suspending" for the convenience of other drivers, so that guidance is unnecessary. It is considered that no problem occurs even if the priority of the guidance is lowered.

  , 2-K is located within a predetermined area (for example, near an entrance), and corresponds to the corresponding vehicle 2-1,..., 2-K. , 2-K, the priority order may be generated for the corresponding automobiles 2-1 to 2-K. This means that when the entire parking lot is full, the status of the automobiles 2-1,..., 2-K is “pause” when the automobiles 2-1,. This is because the priority is generated and the cabin is assigned to such automobiles 2-1,..., 2-K.

  Alternatively, the priority generation unit 12 may generate the priority such that the longer the elapsed time of the vehicles 2-1,..., 2-K, the higher the priority. This is because the car 2-1,..., 2-K, which has a long elapsed time since entering the parking lot, is guided to the passenger compartment preferentially so that the time required for parking does not vary and customer satisfaction is satisfied. This is to improve the degree as a whole.

  Next, the assignment information generation unit 13 of the server device 1 acquires the latest full vacancy information and the latest road information by referring to the vehicle room DB 16 and the road DB 18, and shields the corresponding vehicle with an empty vehicle. A vehicle room having no vehicle ID is allocated in order from the vehicle ID having the highest priority, and allocation information which is information of the allocated vehicle room is generated (S13).

  Next, the allocation information transmitting unit 14 of the server device 1 transmits the allocation information to the corresponding automobiles 2-1 to 2-K (S14). The allocation information receiving unit 23 of the vehicles 2-1,..., 2-K receives the allocation information (S23). The car navigation units 24 of the automobiles 2-1 to 2-K execute voice navigation based on the received assignment information (S24). The driver drives in accordance with the voice navigation, and parks in the cabin corresponding to the assignment information. If the driver does not follow the voice navigation, the vacancy information and the lane information are updated accordingly, so the allocation information of the following vehicle is changed according to the latest vacancy information and the latest lane information. , The new assignment information is transmitted to the corresponding following vehicle.

  According to the parking lot navigation system 100 and the server device 1 of the present embodiment, the vacancy information, the lane information, and the status are updated to the latest state each time, and the allocation information is generated based on the updated information. Therefore, information for navigating in the parking lot flexibly and efficiently according to the situation in the parking lot can be transmitted to the automobiles 2-1 to 2-K.

[Modification 1]
Some of the automobiles 2-1,..., 2-K may be self-driving cars. The flow of FIG. 7 is executed in the same manner as in the first embodiment even when the target automobiles 2-1 to 2-K are self-driving cars. The flow in FIG. 8 is executed in the same manner as in the first embodiment except for step S24. In step S24, automatic driving control according to the assignment information is executed instead of voice navigation.
