Abstract
An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.
