ABSTRACT:
A throttle control system includes a valve, an electric throttle unit, a control unit, a throttle sensor, a memory device, and a memory execution unit. The throttle control system operates the memory execution unit to allow the memory device to store an opening signal detected by the throttle sensor as a “detected full opening” of the valve, when energization of the electric throttle unit is stopped by the control unit and the valve stops at a “mechanical full opening” by mechanical operation. Thus, it becomes possible to coincide the actual valve opening of the valve and a “control valve opening” which the control unit recognizes. Therefore, it becomes possible to decrease system variation between the electric throttle unit and the control unit. Moreover, a control accuracy of an air intake amount by the throttle control system can be improved.
