SYSTEM TO CONTROL THE TORQUE OF AN INTERNAL COMBUSTION ENGINE DURING A GEAR|CHANGE

摘要

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 autoraatic transmission (12) with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission (12), the electronic control unit actuates a waste gate valve (68) in a closing direction with respect to a position of the waste gate valve (68) 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.
