Abstract
An electronic control unit 40 calculates a target output torque of an internal combustion engine 10 based on a manipulation amount of an accelerator pedal 60, a vehicle speed, and a state of a transmission gear ratio of an automatic continuously variable transmission 30, and calculates a target opening of a throttle valve 14 based on the calculated target output torque. If the current value of the transmission gear ratio of the automatic continuously variable transmission 30 is smaller than a predetermined value, the target opening of the throttle valve 14 calculated based on the target output torque is limited to be less than or equal to a preset upper limit.
