摘要:
A throttle valve control device is provided which includes a throttle valve mounted in an intake pipe of an internal combustion engine, an actuator which drives the throttle valve so as to change an opening of the throttle valve, an operating condition sensor which detects operating conditions of the internal combustion engine, an accelerator sensor which detects an accelerator pedal position that represents an amount by which an accelerator pedal is depressed by a driver, and a control unit for controlling the throttle valve. The control unit includes a first setting circuit that sets a first target opening of the throttle valve based on the accelerator pedal position detected by the accelerator sensor, a second setting circuit that sets a second target opening of the throttle valve based on the accelerator pedal position detected by the accelerator sensor, and the operating conditions of the engine detected by the operating condition sensor, and a control circuit that compares the first target opening with the second target opening, and controls the actuator based on the larger one of the first target opening and second target opening.
