PROBLEM TO BE SOLVED: To control low-speed running of a motor-driven vehicle while alarming, by making again its accelerator operate, when colision is shown by the defective collision sensor. SOLUTION: Judging whether a motor 1 or a motor control circuit 17 is abnormal or not, the emergency stop of a motor-driven vehicle is performed when judging them abnormal. Then, judging the state of a phone switch 15 when it is inoperative and it is in OFF state, the value of its invalid flag is made zero. Next, judging the state of a bumper sensor 16 when the stop of the vehicle is not based on the bumper sensor 16 and it is in ON state, the value of its inoperative flag is set as a level one and the deceleration control of the vehicle is perfomed to park the vehicle. When the bumper sensor 16 becomes OFF, the value of its inoperative flag is made zero. Then, when an accelerator lever 12 is in ON state, the speed of the vehicle is controlled to make it run at a corresponding speed to its accelerator control input, and when the accelerator lever 12 is in OFF state, its deceleration control is performed to park it. |
