摘要： A method and apparatus for learning the neutral position of vehicle steering angle, in which first neutral position decision means decides that the steering shaft is at a neutral position when a running speed detector detects that the vehicle speed is not less than a predetermined threshold level, that the difference in peripheral speed between the right and left drive wheels is smaller than a predetermined first straight-running threshold value and also when a steering shaft reference position sensor continues to detect a reference position of the steering shaft for at least a first count time. The vehicle steering angle is computed on the basis of the angular displacement from the neutral position thus learned.

摘要： 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.

摘要： A control apparatus for controlling the output of a vehicle equipped with an internal combustion engine. The control apparatus includes a torque control unit and an electronic control unit, is electrically connected to various sensors for detecting the running conditions of the vehicle, and is capable of controlling, e.g., the operations of a throttle valve and an ignition plug, to thereby control the driving torque of the engine. The control apparatus calculates a reference driving torque of the engine on the basis of the vehicle speed, and also calculates a slippage of the driving wheels on the basis of a deviation of peripheral speed between the driving and driven wheels. A correction torque for the reference driving torque, which is calculated by the control apparatus on the basis of the detected slippage, is subjected to restriction in accordance with the vehicle running conditions, and the reference driving torque is corrected in accordance with the restricted correction torque, to obtain a target driving torque. Thus, the control apparatus controls the operations of the throttle valve and ignition plug such that the actual driving torque of the engine coincides with the target driving torque.
