ABSTRACT:
An apparatus for controlling an automotive vehicle including an engine and an automatic transmission. The apparatus is operable upon generation of an engine-output control command requiring an output of the engine during a shift-up action of the transmission initiated in the absence of the engine-output control command, and includes a shifting-progress calculating portion operable to calculate a degree of progress of the shift-up action of the transmission after a moment of generation of the engine-output control command, on the basis of a change of a rotating speed of a rotary element which changes with the progress of the shift-up action, and a gradual-engine-torque-increase control portion operable to control the engine on the basis of the degree of progress of the shift-up action calculated by the shifting-progress calculating portion, so as to gradually increase an output torque of the engine with the progress of the shift-up action.
