Abstract
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.
