ABSTRACT:
A torque limiting device for motors in electrically driven vehicles includes a control device for controlling an electric driving power supplied to a motor in an electrically driven vehicle; a detecting section for detecting a driven state of the motor and outputting an output signal of the motor; and an upper electric driving power limit setting device in which a plurality of restricting values corresponding to the output signal from the detecting section are previously set, wherein the upper electric driving power limit setting device gives a command to the control device to restrict an upper limit of the driving power on the basis of one of the plurality of restricting values when the output signal is outputted, thereby limiting a torque of the motor.
