<p>PURPOSE:To forcibly stop a vehicle by judging an unmanned traveling state of the vehicle based on the assembly of plural state recognition signals so as to cutoff the current to an ignition coil and also keep the current to the solenoid valve of a brake valve. CONSTITUTION:A state recognition signal 3 comprises a speed signal 3a, accelerating signal 3b and door signal 3c, and is inputted into a judgement circuit 5. The stoppage of a vehicle is confirmed depending on the speed signal 3a and the opening of an accelerator pedal is recognized depending on the accelerating signal 3b, thus operating the solenoid valve 1 of a brake valve 2 so as to seal a braking pressure. Next, the opening of a door is recognized by the door signal 3c, the output of a buzzer 9 is performed. Further, the action of the vehicle is detected by the speed signal 3a and at the motive state, an ignition off signal is outputted into a transistor 6 so as to turn off a relay circuit 7, thus cutting-off the current to the ignition coil 4.</p> |
