Abstract
An electronic throttle control system has a throttle valve to be operated by an electric motor, and an electronic control unit for calculating a target opening degree of the throttle valve depending on a first preset vehicle speed desired by a vehicle driver, so that a vehicle is controlled to automatically run at the preset vehicle speed. When an external module, for example, an ACC module, is added to the electronic throttle control system, and a second preset vehicle speed is inputted from the external module to the electronic control unit the electronic, the electronic control unit selects one of the first and second preset vehicle speeds, which is lower than the other. Then, the target opening degree of the throttle valve is calculated based on the selected preset vehicle speed.
