Abstract: During an upshift of an mechanical speed change mechanism, electric power generated by a first motor is reduced by a given electric power, from a start point of an inertia phase, such that an absolute value of the first motor torque is reduced, and an AT input rotational speed becomes more likely to be reduced. Thus, the upshift of the mechanical speed change mechanism is made more likely to proceed, and variation of drive torque is suppressed.

A target gear ratio of a CVT is determined from a value obtained by correcting the value correlated with the basic required driving force based on a maximum amount of vehicle speed change at the current time point and an amount of vehicle speed change from the start of a gear ratio control up to the current time point.

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.
