Abstract: A control system controls a hybrid vehicle having an engine for rotating a drive axle, an electric motor for assisting the engine in rotating the drive axle, and electric energy storage means for supplying electric energy to the electric motor. The control system has an electric motor control unit which calculates an output power of the electric motor depending on an operating status of the hybrid vehicle and assists the engine based on the calculated output power of the electric motor. The electric motor control unit also reduces the output power of the electric motor when the rotational speed of the engine or the speed of the hybrid vehicle exceeds a predetermined value.

Abstract: A system for controlling motive force of a vehicle having an engine and a continuously variable automatic transmission connected to the engine to transmit engine torque to a drive shaft of the vehicle. In the system, a desired motive force is calculated or determined from the detected accelerator (pedal) position and vehicle speed, and based on the determined motive force a desired engine speed, more specifically a drive shaft speed of the transmission, is calculated or determined. Then inertia torque acting on the vehicle is calculated or determined based on at least the determined speed and detected speed, and a desired throttle opening is corrected by the determined inertia torque when the vehicle accelerates or decelerates. With the arrangement, the vehicle response delay due to the inertia torque is adjusted and hence, drivability and fuel economy performance are enhanced.

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.
