摘要： A system is for controlling a suspension performance detecting the road surface condition in front of an automotive vehicle. A road surface sensor generates an output corresponding to the size of roughness on a road surface located at a predetermined distance in front of the vehicle. A suspension damping coefficient is changed to a smaller value upon lapse of a delay time. The delay time is calculated on the basis of the output of a speed sensor, the delay time being the time required for the wheel to reach the detected rough roads surface. The changing of the suspension damping coefficient occurs on condition that the output of the road surface sensor falls within a control region defined by a lower threshold value and an upper threshold value. Accordingly, the change of the suspension damping coefficient to a smaller value is inhibited when an extremely rough road surface is detected in front of the vehicle, whereby a bottoming out of the suspension which may occur is prevented when the vehicle runs over the extremely rough road surface. Further, the ride feeling is improved when the vehicle runs over a moderately rough road surface.

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： 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 first measured value of a specific physical quantity at a target portion is correlated with a damage evaluation index to calculate a damage degree corresponding to the first measured value. The specific physical quantity is measured at least once at a position corresponding to the first measurement position in another time period having a different usage elapsed time from that of the first measurement, and these second and subsequent measured values are correlated with damage degrees calculated based on temporal changes corresponding to the second and subsequent measurements. A new damage evaluation index is approximately calculated based on a relationship between the first, second, and subsequent measured values and the damage degrees corresponding to the first, second, and subsequent measured values.
