Abstract

PURPOSE: To eliminate overrun of an electric motor vehicle even when a controller is disconnected in wires by using a control circuit such as an oscillator interlocked with an acceletator pedal, amplifier, variable reactor, rectifying circuit, inversion smoothing circuit or the like.
CONSTITUTION: The signal from an oscillator OSC is fed through an amplifier A1, a variable reactor VL interlocked with an accelerator pedal, a diode D1 and an inversion smoothing circuit INS to provide a motor control signal from a terminal Vo. Since the input signal of the circuit INS is negative half-wave rectification signal and an electric circuit including the accelerator is energized by a battery as a power supply, no lower potential than the ground GND is applied to a control circuit. Thus, even if a disconnection of wires or like fault occurs at the reactor VL, the output of the circuit INS does not become high potential and, accordingly, an electric motor vehicle does not overrun.
