ABSTRACT:
A system for controlling motive force of a vehicle having an engine and an automatic transmission connected to the engine to transmit engine torque to a drive shaft of the vehicle, wherein a control mode is selected from among a plurality of predetermined control modes in response to a calculated desired motive force and vehicle speed such that the fuel economy is enhanced and engine torque and speed (gear) ratio are controlled in response thereto. Moreover, the desired motive force is calculated by obtaining a difference between the wide-open-throttle motive force and the full-closed-throttle motive force and by multiplying the difference by a calculated ratio of motive force. Furthermore, the calculated desired output of the engine and the desired gear ratio are controlled such that the desired motive force is generated when the desired motive force is discriminated to be achievable. Thus, the engine and the automatic transmission are controlled in conjunction and the desired motive force is appropriately obtained. The speed (gear) ratio is changed to effect the desired motive force. With the arrangement, fuel economy and emission performance are enhanced.
