ABSTRACT:
A method and system for preventing the movements of an electric vehicle in a direction opposite a desired direction are described herein. The electric vehicle comprises an electric motor linked to at least one wheel of the vehicle. The method comprises detecting the direction of the desired movement; detecting a movement of the vehicle in the direction opposite the desired direction; calculating a torque to be applied by the motor to the at least one wheel to counteract the movement of the vehicle in the undesired direction; and applying the counteracting torque to the at least one wheel via the electric motor.
