Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a schematic explanatory view showing an example of a system for preventing unauthorized use of a vehicle-mounted device according to an embodiment of the present invention. In FIG. 1, a system for preventing unauthorized use of an on-vehicle device includes an on-vehicle device 10 as an on-vehicle device and an engine electrical system 20 on the vehicle side.
Are connected by a cable via a connector 40.

The vehicle-mounted device 10 can be mounted at a position such as a dashboard or a hood of a vehicle (not shown) that does not obstruct the driver.

The vehicle-mounted device 10 includes a CPU 11, a storage device 12, a registration signal input unit 13, a key shape reading signal input unit 14, an engine start state signal input unit 15, an engine speed signal input unit 16, and a transmission / reception unit 18. Is provided. The CPU 11 performs comparison determination and various controls described later.

First, data such as a number, a vehicle number, and a vehicle type can be registered in the storage device 12 via the registration signal input unit 13 when the vehicle-mounted device 10 is purchased and installed.

The storage device 12 also receives a key shape signal input from the engine electrical system 20 via the connector 40 via the key shape read signal input unit 14 and an engine start state signal to the engine start state input unit 15. And an engine speed signal is supplied via the engine speed input unit 16 and stored as a key shape read signal 100, an engine start state signal 110 and an engine speed signal 120.

The storage device includes, for example, a ROM and a RAM. The ROM stores own vehicle information and control data, and the RAM temporarily stores a key shape read signal 100, an engine start state signal 110, and an engine speed signal 120. It is memorized.

The transmission / reception means 18 transmits a comparison result signal, data such as a vehicle number and a vehicle type to the outside, and receives a signal from an external device.

On the other hand, the engine electrical system 20 comprises a starter section 21, a control section 24, a starter motor 25 and an engine speed detecting section 26. The starter unit 21 has an ignition switch 22 and a key shape reader 23 composed of a scanner for reading the key shape of the starter key 17.

When the starter key 17 is inserted into the ignition switch 22, the electric system of the vehicle itself and the power supply of the vehicle-mounted device are turned on.

By inserting the starter key 17 into the ignition switch 22, the key shape is read by the key shape reading device 23. The key shape reader 23 reads the key number, the vehicle number, and the vehicle type based on the shape of the groove of the key 17, the number of grooves, and the like.

The key number, vehicle number, and vehicle type data read by the key shape reading device 23 are input to the key shape reading signal input section 14 of the vehicle-mounted device 10 via the connector 40, and The registered data is provided for comparison with corresponding data stored in the storage device 12.

In the engine electrical system 20, when the starter key 17 is turned to start the engine,
The starter motor 25 is started, an engine start state signal is sent from the control unit 24 to the engine start state input unit 15 of the vehicle-mounted device 10 via the connector 40, and the engine speed at this time is detected by the engine speed detection unit. The detection result is sent from the control unit 24 to the engine frequency signal input unit 16 of the vehicle-mounted device 10 via the connector 40.

In the vehicle-mounted device 10, the signals (data) are converted into a key shape reading signal 100, an engine starting state signal 110, and an engine speed signal 120 by the CPU 11.
And used as data for comparison determination or as a timing signal for comparison determination.

Next, the operation of the system for preventing unauthorized use of the vehicle-mounted device will be described with reference to the flowchart of FIG.

At the time of purchase of the vehicle, the key number, the vehicle number and the vehicle type data of the vehicle owned by the vehicle owner (registrant) are inputted using the vehicle type registration device 30 provided in the vehicle-mounted device 10. Are registered in the storage device 12 in advance.

Thereafter, when the user of the vehicle-mounted device 10 attaches the vehicle-mounted device 10 to the vehicle owned by the user and inserts the key 17 into the ignition switch of the starter unit 21, the electric system such as the engine electrical system of the vehicle can be started. (Step ST200). At the same time, the power is also turned on to the vehicle-mounted device 10, and each unit of the vehicle-mounted device 10 becomes operable (step ST201).

When the key 17 is inserted, the shape of the key 17 is read by the key shape reading device 23 in the engine electrical system 20, and based on this, the key number, vehicle number and vehicle type data of the vehicle are determined. On-board unit 10
And is temporarily stored in the storage device 12 (step ST202).

Next, the CPU 11 of the vehicle-mounted device 10
The input vehicle data and the vehicle data registered in advance are compared and determined. If both are "matched", the vehicle-mounted device 10 can be used as in the next step ST204. The vehicle-mounted device 10 cannot be used (step ST210).

As described above, since the comparison is made at the timing when the key is inserted, it is possible to prevent the injustice that the user replaces the vehicle-mounted device 10 with a different vehicle.

Next, even after the use of the on-vehicle device 10 is enabled, it is determined in step ST205 whether or not the state of the engine start signal has changed. A comparison determination similar to that in step ST203 is performed. In this case, at this timing, the key number, the vehicle number, and the vehicle type data based on the key shape are taken into the vehicle-mounted device 10 as described above, and are compared with data registered in advance. If it is determined as “mismatch” in the comparison determination in this step, the use of the vehicle-mounted device 10 becomes impossible.

In this way, even if the vehicle-mounted device 10 can be used in one vehicle and the vehicle-mounted device 10 is replaced with another vehicle, such fraud can be prevented.

Next, when it is determined in step ST205 that the state of the engine start signal is not changed (ON state), the engine start signal is transmitted to the vehicle-mounted device 10 again. Since the engine speed signal is input, it is determined based on these signals whether or not the engine speed is in the idling state (for example, the rotation speed is 1000 or less) and the condition of the engine start state (step ST207). If the condition is satisfied, the same comparison judgment as described above is performed. If they match, the use of the vehicle-mounted device 10 becomes possible, and if they do not match, the use of the vehicle-mounted device 10 becomes impossible.

As described above, by performing the comparison and determination at the timing of the idling state after the engine is started, the user can switch the vehicle-mounted device 10 to another vehicle after inserting the key and starting the engine. Even if the wrongdoing is done, this can be prevented.

When the result of the comparison is "mismatch" in each step and the use of the vehicle-mounted device 10 becomes impossible, the vehicle-mounted device 10 sends the signal L to that effect to the outside by the transmission / reception means 18. (Step ST21)
2).

Next, a toll collection system for toll roads using the vehicle-mounted device 10 will be described with reference to FIG.

In the figure, D is a toll road, 51 is an entrance lane, and 52 is an exit lane. Reference numeral 50 denotes a vehicle on which the vehicle-mounted device 10 is installed. Inlet lane 51 and outlet lane 5
Each of the units 2 is provided with management means 51A and 52A for performing wireless communication with the on-vehicle device 10 and performing charge collection calculation. Each of the management means 51A and 52A communicates data with a higher-level management device 53 provided in a monitoring center or the like.

In such a system, when the vehicle 50 having the vehicle-mounted device 10 passes through, for example, the entrance lane 51, the vehicle 50 transmits a signal based on the data of the vehicle and the comparison result. In this case, if the comparison determination signal is a “mismatch” signal, it means that the vehicle-mounted device 10 cannot be used, and the management unit 51A instructs the vehicle to stop.

The management means 51A instructs the stop of the traffic, and also transmits "unable to use the vehicle-mounted device 10" to the host management device 53 together with the vehicle data. The host management device that has received this registers the vehicle in the blacklist.

When passing through the entrance lane 51,
Even if the comparison determination signal from the on-vehicle device 10 is “match”, when the vehicle is passed through the exit lane 52 in the vicinity of the exit lane 52, if an illegal operation such as replacing the on-vehicle device 10 with another vehicle is performed. Since the "mismatch" signal is transmitted, the management means 52A of the exit lane 52 instructs to stop the traffic of the vehicle, thereby preventing the illegal use.

When the comparison judgment signal from the vehicle-mounted device 10 is a "match" signal in both the entrance lane 51 and the exit lane 52, the charge calculation process can be performed only by the signal from the vehicle-mounted device 10. There is no need to make a distinction, and the system can be applied to unmanned lanes to provide a convenient system.
