Claims

[Claims for Utility Model Registration] Based on the operation amount of the accelerator operator, a current command value to be applied to the AC motor for driving is formed, and the current command value signal is converted into pulses by a pulse width modulator, and the pulse In a travel control device for an electric vehicle that drives a power converter based on a signal to control the current applied to an AC motor; motor rotation/stop detection means for detecting whether the AC motor is in a rotating state or a stopped state; and an accelerator operation detection means for detecting whether or not the accelerator operator is operated; and the pulse width modulator compares the current command value signal and the triangular wave with a triangular wave generator. a comparator that outputs a pulse signal when the motor is stopped; and when it is detected that the motor is stopped and there is no accelerator operation, the amplitude of the triangular wave is made smaller than the reference amplitude when the motor is rotating; A running control device for an electric vehicle, comprising: an amplitude regulator that returns the amplitude to the reference amplitude after a predetermined transition time when motor rotation is detected.
