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.

Electronic park brake system for electric vehicles

A control apparatus is provided for use in an electric vehicle having a throttle input device. The throttle input device is operable by a rider for generating a throttle signal for controlling the speed of the electric vehicle. The control apparatus, which adjusts the throttle signal, includes a rider input mechanism and a control device. The rider input mechanism can be manipulated by the rider to provide a given input. The control device is coupled to the rider input mechanism and to the output of the throttle input device. The control device adjusts the throttle signal based on the given input provided by the rider input mechanism.

Method and apparatus for adjusting throttle control signals in electric vehicles

A throttle control system is provided for generating a throttle control signal in an electric vehicle. The throttle control system includes: a throttle position sensor operable to detect a throttle twist input by an operator and to responsively generate a throttle twist input signal; a controller operatively coupled to the throttle position sensor for receiving the throttle twist input signal and responsively generating a throttle control signal; and a feedback circuit operatively coupled to the controller for receiving the throttle control signal and outputting a corresponding feedback signal to the controller; wherein the controller compares the feedback signal and the throttle control signal to detect an error condition in the throttle control signal, and when an error condition is detected, determines a responsive action corresponding to the severity of the error condition.
