Abstract
A time-dependent engine output power characteristic curve for an engine output power to vary therealong to a target value which corresponds to an indication of intention of the driver for acceleration or deceleration (e.g., the amount of depression of the accelerator pedal) is established based on the difference between a target engine output power and an actual engine output power. Then, a target rate of change of the rotational speed of the engine and a target rate of change of an indication of an engine load are established so that the actual engine output power varies along the engine output power characteristic curve, and the throttle valve and the continuously variable transmission are controlled using the target rates thus established.
