Abstract
An electronic throttle control system is provided, which comprises an accelerator pedal position sensor, a control unit, and a biasing mechanism. The accelerator pedal position sensor detects a position of an accelerator pedal. The throttle actuator actuates a throttle valve to rotate. The control unit determines a target throttle position based on the accelerator pedal position, and controls an operation of the throttle actuator in accordance with the determined target throttle position. The biasing mechanism provides rotational force to the throttle valve such that an opening angle of the throttle valve while the throttle actuator is not powered is greater than a predetermined idle opening angle.
