Abstract:
1. A throttle control system comprising: a valve for opening and closing an air intake passage; an electric throttle unit for electrically driving the valve, and to stop the valve at a mechanical full opening by a mechanical operation when energization of the electric throttle unit is stopped; an control unit for controlling energization of the electric throttle unit; a throttle sensor for detecting an opening of the valve; a memory device for storing data corresponding to an opening signal of the throttle sensor; and a memory execution unit for enabling the memory device to store data corresponding to the opening signal detected by the throttle sensor as a detected full opening of the valve, when energization of the electric throttle unit is stopped and the valve is stopped at the mechanical full opening by mechanical operation; wherein the memory execution unit enables the memory device to store data corresponding to an opening signal detected by the throttle sensor as the detected full opening of the valve, before beginning energization of the electric throttle unit.
