ABSTRACT:
By processing in a control processor 71 signal indicating the amount or degree of pushing-down of the accelerator pedal 2a and signals indicating the non pushing down and full pushing-down of the acceleration pedal 2a, the control unit 7 executes the judgment for determining whether the detected accelerator state is normal or anomalous. In case of judgment of "normal", a usual motor control is executed, whereas in case of judgment to be "anomaly", the system is tentatively designated to be "a state under which the anomaly is being detected". After a specified time lapse, a rejudgement operation is executed, and further when the anomaly is not solved even in this rejudgement operation, the situation is regarded to be a "real anomaly", and an anomaly procedure e.g. to stop current to the motor is executed. When the anomaly state is solved in the rejudgement operation, it is judged to be normal again.
