A motor control system for an electric vehicle has a brushless DC motor. An electronic system for controlling the motor includes a main electrical supply device for supplying power half-bridges for supplying phases of the motor and provided with upper arms, which are equipped with first electronic switches, and lower arms, which are equipped with second electronic switches. A programmable computer controls the first and second electronic switches to implement a first drive mode of the motor, and a second freewheeling mode. A safety circuit produces an emergency braking mode and has third electronic switches for short-circuiting the lower arms of the half-bridges in parallel with the second electronic switches. The third electronic switches are controlled by an additional switching circuit suitable for closing the third switches in order to perform the emergency braking. The additional switching circuit is supplied by a secondary electrical supply device.
