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.

Dispositif limiteur de couple pour moteurs de véhicules alimentés à l'électricité. Comprend un dispositif permettant de commander l'alimentation électrique d'un moteur de véhicule électrique; une section de détection pour détecter un état de marche du moteur et produire un signal de sortie en conséquence; et un dispositif d'établissement de limites supérieures d'alimentation électrique, dans lequel un certain nombre de valeurs restrictives correspondant au signal de sortie de la section de détection sont préalablement établies, et qui donne au dispositif de commande la commande de restreindre une limite supérieure de l'alimentation en fonction d'une desdites valeurs restrictives lorsque le signal de sortie est produit, de façon à limiter le couple du moteur.
