It is connected to the roadside device I¥32 and displays parking position information. 34 is a route bus vehicle (hereinafter simply referred to as a vehicle)
It is an in-vehicle device that is usually mounted on a vehicle in one-to-one correspondence, and can communicate with the roadside device 32 by electromagnetic induction communication, weak radio wave communication, etc.

In the parking position guidance system having the above configuration, when a vehicle equipped with the on-vehicle device 34 enters an area where communication with the on-road device 32 is possible, the on-vehicle device 34 uses the on-vehicle device number as a vehicle identification information signal to communicate with the on-road device 32 on the road. Send to bag Vrt32. The on-road device 32 sends the received in-vehicle device number to the central processing unit 3.
1, whereby the central processing unit 31 receives the manually input parking position information.

Alternatively, from the parking position information calculated from the operation schedule, a position where the above vehicle can be parked is searched by the onboard device number, and the searched parking position information is displayed on the parking position display 33 via the roadside device 32. This guides the vehicle driver to the parking location.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional parking position guidance system, after the on-vehicle device 34 sends out the on-vehicle device number as an identification information signal, until the parking position is displayed on the parking position display 33. The time is car'F! , assuming that the communication speed between the machine 34 and the road device 32 is 4800 bps, and the communication speed between the road device 32 and the central processing unit 31 is 500 bps, it will take about 8 to 20 seconds, during which time the vehicle will be unable to communicate with the road device 32. Must wait in available area.

Therefore, if the vehicle cannot wait in the communication area of the roadside device 32 that provides parking position information, or if the parking position indicator 3
If the installation of 3 is not possible, there is a problem that the driver cannot be informed of the parking location.

In view of the problems of the conventional parking position guidance system described above, the present invention makes it possible to instantly transmit parking position information to passing vehicles without the central processing unit being aware of vehicles entering the parking lot. The purpose is to provide a parking location guidance system.

(Means for Solving the Problem) The present invention achieves the above-mentioned purpose in a parking position guidance system built in a route bus garage, etc., by using the number etc. of the on-vehicle device installed on the vehicle entering the garage as vehicle identification information. A central processing unit that creates parking position information, a roadside device that receives and stores the parking position information from this central processing unit, and an in-vehicle display on the in-vehicle device, and the central processing unit can display the created parking position information. Weak radio wave communication is sent to on-road equipment in advance.

When the on-vehicle device inquires about the parking position using the on-board device number as vehicle identification information through a narrow-range communication means such as guided communication, the on-road device uses the stored parking position information to identify the sent on-board device number and the vehicle identification information. This is achieved by displaying matching parking position information as the parking position on the in-vehicle display.

(Function) According to the present invention, the central processing unit transmits and stores the parking position information for each on-vehicle device number corresponding to the vehicle in advance to the on-road device without being aware of the approaching vehicle. When the device receives an in-vehicle device number from the vehicle to inquire about the parking location, it searches for the parking location information corresponding to the received in-vehicle device number from the stored parking location information for each in-vehicle device number and searches for the parking location information corresponding to the received in-vehicle device number. This allows the driver to instantly know the parking location on the in-vehicle display.

(Example) Hereinafter, the present invention will be explained by examples using the drawings.

FIG. 1 is a block diagram showing an example of a device configuration for carrying out the present invention, in which 1 is a central processing unit, 2 is a roadside device,
Reference numeral 3 denotes an on-vehicle device mounted on a vehicle, and is capable of communicating with the on-road device 2 by weak radio wave communication, electromagnetic induction communication, or the like. Also.

4 is an in-vehicle display device that receives parking position information from the on-vehicle device 3 and displays it.

FIG. 2 shows the configuration of the above-mentioned on-road device 2, where 5 is a communication unit for a central processing unit and communicates with the central processing unit 1 shown in FIG. 3 is a communication section for transmitting and receiving information, 7 is a control processing section, and 8 is a data storage section.

The present invention, which has such a device configuration, first has a central processing unit 1.
The system transmits information on which vehicle should be parked at which position to the roadside device 2 by manually inputting it or calculating it based on the vehicle operation schedule, etc., and stores the parking position information in advance in the data storage unit 8 using the on-board device number as vehicle identification information. are stored separately by in-vehicle device number. When the vehicle enters the communication area with the on-road device 2, the on-board device 3 on-board transmits the on-board device number, which corresponds one-to-one with the vehicle, to the on-road device 2 as vehicle identification information.

The on-road device 2 searches for the vehicle corresponding to the on-vehicle device number received from the on-vehicle device 3 by searching the vehicle identification information sent from the central processing unit 1 and stored in the data storage unit 8 in advance. The stored parking position information corresponding to the searched vehicle identification information is transmitted to the on-vehicle device 3. The in-vehicle device 3 outputs the received parking position information to the in-vehicle display 4 to display the parking position, so that the driver can know the parking position.

As described above, the present invention allows the on-road device 2 to receive and store parking position information for each vehicle-mounted device number corresponding to the vehicle from the central processing unit 1 in advance, and then transmits the stored information from the vehicle-mounted device 3. The parking position information obtained by searching using the on-board device number is sent to the on-board device 3 and displayed on the in-vehicle display 4.
The burden on the central processing unit 1 is reduced, and other vehicles passing through the area where communication with the roadside device is possible are also reliably informed of the parking location information.

(Effects of the Invention) As is clear from the above explanation, the present invention has the following advantages: (a) Parking position information can be transmitted within the communication time between the on-vehicle device and the on-road device, and is therefore limited to parking positions at gas stations, etc. without any
It is possible to reliably guide passing vehicles to the parking location, and (b
) The central processing unit can transmit the parking position information to the on-road device when the parking position for each on-vehicle device number is determined, so the burden on the central processing unit is reduced; (c)
Since the parking position is directly displayed to the driver using the in-vehicle display, it is possible for a plurality of vehicles to receive guidance on parking position information at the same time in an area where communication with on-road devices is possible.
