Abstract
The disclosed apparatus controls an actual drive force of an automotive vehicle equipped with a continuously variable transmission for transmitting an output of an engine to drive wheels. The apparatus includes an output detector for detecting a currently required output of the vehicle; a speed detector for detecting a current speed of the vehicle; a first device for determining a target drive force of the vehicle based on the detected currently required output and the detected current speed of the vehicle, and according to a predetermined relation among the target drive force, the currently required output and the current speed of the vehicle; and a second device for determining the actual drive force of the vehicle. An adjusting device compares the determined target drive force with the determined actual drive force and controls the output of the engine and/or a speed ratio of the transmission, so that the actual drive force of the vehicle coincides with the determined target drive force.
