Such a powerful sound threatens the criminal and informs the surroundings of an abnormal situation.

FIG. 3 is a diagram showing a main flow of the security state of the vehicle. The conditions for establishing the crime prevention state of the vehicle will be described with reference to FIG. First, the engine key switch 13
Is set to the ON position (step S1), power is supplied to the system, and the vehicle security system of the cash transport vehicle is activated (step S2). When power is supplied to the driver determination device 9, a warning state is set (step S3). If the parking brake sensor 7 is released without making a right / wrong judgment of the driver during the alert state, a warning state is set (step 4). In the warning state, the display 16 flashes, and a buzzer for notifying the warning state is output intermittently. If a preset time has elapsed in the warning state, an abnormal state is set (step 5). In the warning state, if all the doors are closed and the driver's judgment is correct before the preset time elapses, the warning is released (step 6). In the warning state, even if all the doors are closed before the predetermined time elapses, if the driver fails to make the determination a predetermined number of times, the state becomes abnormal (step 7). When an abnormal state occurs, the input of a password is not accepted within a preset time. As described above, the vehicle security system according to the present invention changes the security state of the vehicle in accordance with the conditions for establishing the security state of the vehicle based on a combination of input signals indicating whether the driver has made a determination as to whether the driver is correct, whether the door is open or closed, and whether or not the parking brake is activated. The state is controlled to one of four states of a warning state, a warning release state, a warning state, and an abnormal state to prepare for occurrence of an abnormal situation.

Next, one embodiment of determining whether the driver is correct or not by the driver determination device 9 will be described. The driver determination device 9 includes a password registration key switch 17, a password key 14, a password enter key 15, and a display 16. Before starting the operation of the vehicle security system, a personal identification code that is used as a criterion for determining whether the driver is correct or not is registered. The fact that all doors of the vehicle are closed and that the parking brake is activated are prerequisites for enabling the registration of a password. When the engine key switch 13 is set to the ON position to start the system, the system key 19 is inserted into the password registration key switch 17 of the driver determination device 9 and the system is set to the SET position. When the buzzer sounds, the registration is possible. When a plurality of password keys 14 are pressed, a password is input, and a password enter key 15 is pressed, a buzzer sounds to notify the completion of registration when registration is completed, and a buzzer sounds to notify registration failure when registration is failed. Sounds. If the password registration fails, the registration must be restarted from the beginning. After the password registration is completed, the password registration key switch 17 is returned to the ON position, the system key 19 is extracted, and stored at a center or the like. The system key 19 is set to the O
The structure is such that it can be extracted only at the N position.

Next, a method for determining whether the driver is right or wrong will be described. In a vehicle for which the password registration which is a driver's judgment criterion is completed, all doors of the vehicle are closed,
It is a condition that the correctness of the driver cannot be determined unless the parking brake is activated and the system is activated. The system is started by turning the engine key switch 13 to the ON or START position and starting the engine. Thereafter, the password is pressed by pressing the password key 14 of the driver determination device 9 to input the password. After inputting the password, the user presses the password enter key 15 to check with the registered password. If the result of the verification is positive, a buzzer sounds to indicate that the driver is correct, the accelerator interlock 6 is released, and a warning release state where normal traveling is possible is established. If the driver makes a mistake, a buzzer sounds to inform the driver of the error. If the error is repeated a preset number of times, no input is received during the preset time, and at the same time, an abnormal state occurs and each security device operates. Also, the system power supply is maintained. In addition,
It is possible to forcibly stop each security device by the control device power key switch 18. The control device power key switch 18
It is located on the control panel of the control device 12 and can be turned off by switching on the main power supply of the system by inserting the system key 19. Use when you have forgotten your password and become abnormal. Normally the control device power key switch 18
Is turned on, the system key 19 is pulled out, and the system key 19 is managed at a center or the like. The system key 19 is structured so as to be released only when the control device power key switch 18 is turned on. When the control device power key switch 18 is turned off, the engine key switch 13 is turned on. Even the system does not start. In addition, the system power is turned off even when the vehicle is in an abnormal state. Control device power key switch 18 and password registration key switch 17
The key can be kept the same key and strictly managed by the center to maintain security.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example,
As a method for determining the correctness of the driver, a password input method using a password key is used in the above embodiment, but a magnetic card, an IC card, a fingerprint, or the like may be used. In addition, a camera system is incorporated in the vehicle, and the front and rear of the vehicle, the situation inside the current safe, etc. are displayed on a monitor, and when the security system of the vehicle is controlled to an abnormal state, the recording system is activated,
Outputs the recording of images in abnormal conditions, or incorporates a position confirmation system such as GPS into the vehicle, and outputs information about abnormal situations from the vehicle to the base station when the vehicle's security system is controlled to abnormal conditions. The driver determination device 9
An emergency button is provided inside the current safe, and by pressing the emergency button, the crime prevention state of the vehicle is controlled to an abnormal state, and the output in an abnormal state such as a threatening sound is automatically performed, or the crew can carry it. It is also possible to control the crime prevention state of the vehicle to an abnormal state and operate each crime prevention system by remote control with a transmitter that performs the operation.

[0012]

According to the vehicle crime prevention system of the present invention, the crew member does not operate the emergency button, appropriately controls the crime prevention state of the vehicle, and automatically detects the occurrence of an abnormal situation.
It is possible to reliably operate the security system and prevent crime in cash transport vehicles. In addition, in the conventional security system, the engine of the vehicle was stopped at the time of an abnormal situation.Therefore, there was a possibility that an accident would occur when the vehicle stopped at a railroad crossing or at an intersection, etc. Therefore, low-speed movement is possible, emergency danger evacuation is possible, and safety is excellent.
