In a turning control apparatus for a vehicle, a torque calculation unit calculates a target lateral acceleration of the vehicle according to detection signals from a steering angle sensor for detecting the direction of a steering wheel and a vehicle speed sensor for detecting the speed of the vehicle. It then sets target driving torque of the engine according to the target lateral acceleration. An electronic control unit controls the operation of a torque control device for reducing driving of the engine so that the driving torque of the engine is a target driving torque independent of manipulation by the driver. This thereby rapidly estimates lateral acceleration applied to the vehicle during turning and prevents control delay to enable stable and positive traveling through a curved road.

Turning control apparatus for vehicle

A motor vehicle output power control system quickly reduces the drive torque produced by an engine on a motor vehicle depending on the magnitude of a lateral acceleration which is produced when the motor vehicle makes a turn, or the amount by which drive wheels slips when the motor vehicle is accelerated. A target drive torque depending on the lateral acceleration and a demanded drive torque demanded by the driver of the motor vehicle are added at a predetermined ratio into a turn target drive torque, which is selected as a final target drive torque. The motor vehicle output power control system includes an electronic control unit for controlling an actuator to lower the output drive torque of the engine, independent from controlling action of the driver, such that the output drive torque of the engine is equalized to the final target drive torque.

System for controlling the output power of a motor vehicle

A rear wheel steering system of the trailing arm type suspension for rear wheels having a trailing arm for supporting at the rear portion thereof a rear wheel and extending essentially in the longitudinal direction of a vehicle body by pivotally securing the front end thereof to the body side. Lateral arms are rotatably coupled at the outer ends thereof to the rear portion of the trailing arm and extending essentially in the lateral direction of the vehicle by pivotally securing the inner ends thereof to the vehicle body. The trailing arm allows the front portion thereof to displace essentially in the lateral direction of the vehicle. The rear wheel suspension arrangement allows the trailing arm to displace substantially in the lateral direction of the front end thereof and which comprises an actuator for steering a rear wheel by operating the trailing arm to displace the front portion of the trailing arm essentially in the lateral direction of the vehicle.
