摘要： Various steering coefficients (KB, KC, KG) are decided in accordance with a detected car speed (V), while a correction amount (X) and a correction factor (Y) are determined by fuzzy reasoning in accordance with a detected road surface friction coefficient (.mu.), road surface gradient (.alpha.), and lateral acceleration (G). A reference in-phase steering amount (.delta.RB), equal to a product of a reference in-phase steering coefficient (KB) and a detected steering wheel angle (.theta.H), is corrected by an in-phase correction steering amount (.delta.RC), which is equal to a product of an in-phase steering coefficient (KC) and the detected steering wheel angle (.theta.H), with a delay determined by a time constant (T) calculated from the correction amount (X), to thereby determine a corrected in-phase steering amount (.delta.R). A corrected anti-phase steering amount (.delta.G), obtained by multiplying a reference anti-phase steering amount (.delta.GB), equal to a product of the anti-phase correction coefficient (KG) and a detected steering wheel angular velocity (.theta.HA), by the correction factor (Y), is added to the corrected in-phase steering amount (.delta.R), to thereby obtain a rear-wheel steering amount (.delta.) on which the rear wheels are so steered as to match the road surface friction coefficient, road surface gradient, and lateral acceleration.

摘要： A suspension system includes air suspensions provided for individual wheels of a motor vehicle, each including a damping force switching actuator and an air supply/discharge actuator for the air spring. It further includes sensor for detecting the steering angle of a steering wheel, a sensor for detecting the vehicle velocity, and a control device for controlling the damping force and spring constant of each air suspension in accordance with the values detected by means of the sensors. This thereby reduces the roll of the vehicle body and modifies the steering characteristic of the motor vehicle.

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 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.

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.
