Abstract: A method and system is provided for determining a direction of movement of an electric vehicle. The method and system includes determining the direction of rotation and the direction of torque of a motor shaft, determining an operating gear of the vehicle, and determining a previous direction of movement of the vehicle. The method and system then determines if the vehicle is moving forward or backwards. The method and system also determines whether the vehicle is motoring (i.e., converting electric power to mechanical power) or generating (i.e., converting mechanical power into electric power).
