Abstract
A motor vehicle output power control system effects a slip control process for preventing the drive wheels of a motor vehicle from slipping against unstable maneuverability and a trace control process for preventing the motor vehicle from failing to make a turn due to an excessive lateral acceleration. The motor vehicle output power control system has a torque control unit for reducing the drive torque produced by the engine irrespective of controlling action of the driver. A target speed for the drive wheels is established on the basis of the motor vehicle speed, and a reference drive torque for the engine is set depending on the target speed for the drive wheels. Based on a slip of the drive wheels, a target drive torque for the engine is established. The torque control unit is controlled by an electronic controller so that the drive torque produced by the engine is equalized to the target drive torque. The reference drive torque is corrected on the basis of the slip of the drive wheels, thus calculating the target drive torque. The drive torque of the engine can be quickly lowered in order not to unduly exceed maximum frictional forces between the road surface and the drive wheels. The motor vehicle is controlled by the motor vehicle output power control system to run safely with improved control responses because of a reduced number of corrective factors for control.
