[0027]
The memory 224 includes a flash memory, a RAM, and the like, and stores a computer program, data accompanying processing by the control unit 223, vehicle data, and the like. As the vehicle data, a vehicle registration number (for example, Nagoya 333-4289), a vehicle length, a vehicle width, a vehicle height, a vehicle type, a vehicle user name, and a vehicle user address are used.
[0028]
Next, the operation of the present embodiment will be described with reference to FIGS. FIG. 5 is a flowchart showing each process of the road device 310, the management computer 320, and the service computer 340.
[0029]
First, the road unit 310 transmits a request signal for requesting vehicle data to the parking prohibition area (circular hatched portion in FIG. 1) at regular intervals.
[0030]
Here, when the vehicle 300 is parked in the no-parking zone, the control unit 223 of the smart plate 220 mounted on the vehicle 300 receives the request signal via the antenna 221 and the wireless unit 222 every time the request signal is received. 224 is transmitted via the radio unit 222 and the antenna 221.
[0031]
On the other hand, the roadside device 310 determines whether or not the vehicle registration number is received at regular intervals (for example, one minute) (S100). Then, every time it is determined that the vehicle registration number has been received, the received vehicle registration number (transmission signal) is transmitted to the management computer 320 (S110).
[0032]
Here, according to the vehicle registration number sent from the road unit 310, the management computer 320 receives the same vehicle registration number by the road unit 310 a predetermined number of times (for example, 30 times) within a certain period, It is determined that the vehicle 300 corresponding to the car registration number is parked in the no-parking zone (S120). That is, a parking violation vehicle is detected.
[0033]
Along with this, the management computer 320 transmits the message that “parking infringing vehicle has been detected” and the vehicle registration number to the service computer 340. Is alerted to the vehicle user, and the vehicle user is notified to move the vehicle 300 promptly (S140).
[0034]
Thereafter, after a lapse of a certain period (for example, one hour), the service computer 340 determines whether or not the same vehicle 300 as described above is parked in the no-parking area via communication with the management computer 320 (S150). ).
[0035]
For example, if it is determined that the same car registration number as described above has been received by the management computer 320 via the roadside machine 310 even after a certain period of time (for example, one hour), the same vehicle 300 as described above is moved to the parking prohibited area. Is transmitted to the police computer 335, that the vehicle 300 is malicious and that the vehicle has been detected as being malicious. Thus, it is possible to notify the police that the vehicle 300 is parked in the parking prohibited area.
[0036]
Further, in S150, when the same vehicle registration number as described above is not received by the management computer 320 via the on-road unit 310 after a certain period of time, it is determined that the vehicle has moved from the no-parking zone, and a warning message is displayed. The warning by the light 330 is stopped (S160).
[0037]
Hereinafter, the operation and effect of the present embodiment will be described. In the present embodiment, the road unit 310 receives the vehicle registration number transmitted from the smart plate (vehicle wireless device) 220 of the vehicle 300 located in the parking prohibited area, and the management computer 320 receives the vehicle registration number. Since it is determined whether or not the vehicle is parked in the parking prohibited area according to the car registration number, it is possible to detect a parking violation vehicle parked in the parking prohibited area without a person going to the parking prohibited area.
[0038]
Further, in the conventional on-vehicle equipment, the vehicle position information, the operation state of the parking brake, the setting state of the automatic transmission is detected, and based on these various detected information and map data, the vehicle is parked in the parking prohibited area. A method for determining whether or not there is a change has been proposed (see, for example, JP-A-2002-243455).
[0039]
In this case, a service for detecting a parking violation vehicle must be implemented unless an in-vehicle device that determines whether or not the vehicle is parked in the parking prohibited area based on various types of detection information and map data is installed at a user's burden. Can not. On the other hand, in the present embodiment, if the smart plate 220 is provided as standard equipment, a service for detecting a parking violation vehicle can be implemented without imposing a heavy burden on the user.
[0040]
(2nd Embodiment)

First, the road unit 310a transmits a request signal for requesting vehicle data to the left area A of the road at regular intervals, and the road unit 310b transmits a request signal requesting vehicle data to the left area B of the road. Is transmitted at regular intervals. Further, the road units 310a and 310b determine at regular intervals whether or not the vehicle registration number is received (S101).
[0044]
For example, when the vehicle 300 enters the left area A, the control unit 223 of the smart plate 220 mounted on the vehicle 300 stores the request signal in the memory 224 every time a request signal is received via the antenna 221 and the wireless unit 222. The stored vehicle registration number is transmitted via the wireless unit 222 and the antenna 221.
[0045]
The roadside machine 310a transmits the received vehicle registration number (transmission signal) to the management computer 320 every time it determines that the vehicle registration number has been received (S110).
[0046]
Here, when the management computer 320 receives the vehicle registration number sent from the road unit 310a, the vehicle corresponding to the vehicle registration number is parked in the parking prohibited area according to the received vehicle registration number. It is determined whether or not there is (S131)
Specifically, when the same vehicle registration number as that received by the on-road unit 310a is received by the on-road unit 310b within a certain period, it is determined that the vehicle has not parked in the parking prohibited area and has moved. I do. Alternatively, when the same vehicle registration number is received not by the on-road unit 310b but by the on-road unit 310a, it is determined that the vehicle has not parked in the no-parking zone and has moved.
[0047]
On the other hand, if the same vehicle registration number is not received by any of the road units 310a and 310b within a certain period, it is determined that the vehicle is parked in the parking prohibited area.
[0048]
In this case, when the management computer 320 executes the process of notifying the service computer 340 (S130), the service computer 340 executes the process of alerting the vehicle user (S140). Thereafter, after a lapse of a certain period (for example, one hour), the service computer 340 determines whether or not the same vehicle 300 as described above is parked in the no-parking area via communication with the management computer 320 (S150). ).
[0049]
For example, if the same vehicle registration number as described above is not received by the management computer 320 via one of the road units 310a and 310b even after a certain period (for example, one hour), the same vehicle 300 as described above is used. It is parked in the no-parking area, and determines that the vehicle 300 is malicious, and transmits to the police computer 335 “a detection of a parking offending vehicle” and an automobile registration number.
[0050]
When the same car registration number as described above is received by the management computer 320 via one of the road units 310a and 310b within a certain period, it is determined that the vehicle 300 has moved from the no-parking zone. Then, the warning by the warning display light 330 is stopped (S160).
[0051]
Next, the operation and effect of the present embodiment will be described. The road unit 310a receives the vehicle registration number transmitted from the smart plate 220 of the vehicle 300 passing on the entrance side of the parking prohibited area, and the road unit 310b receives the vehicle registration number of the vehicle 300 passing on the exit side of the parking prohibited area. After the vehicle registration number transmitted from 220 is received, and the vehicle registration number is received by one of the on-road units 310a and 310b, the same number as the received vehicle registration number is set to the on-road unit 310a within a predetermined period. , 310b, it is determined that the vehicle is parked in the no-parking zone. Thus, similarly to the first embodiment, it is possible to detect a parking violation vehicle parked in the parking prohibited area without a person going to the parking prohibited area.
[0052]
