Abstract
A method and apparatus are provided for securing an electric vehicle from unwanted movement when the electric vehicle is parked. The electric vehicle includes a drive wheel and an electric motor for driving the drive wheel. The method includes the steps of: (a) placing the electric vehicle in an electronic park brake mode; (b) automatically detecting that the electric vehicle is rolling from an initial position; and (c) automatically causing the electric motor to apply a reverse torque to the drive wheel to return the electric vehicle to the initial position or automatically causing the electric motor to lock the drive wheel to inhibit further movement of the electric vehicle.
