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： An apparatus for estimating a vehicle maneuvering state and controlling a vehicle running characteristic includes a controller having a fuzzy estimating function and a neural network function. The controller carries out frequency analysis on vehicle driving parameters such as vehicle speed, steering angle, opening degree of an accelerator, and longitudinal acceleration and lateral acceleration of a vehicle, to thereby determine a mean value and variance of each parameter.

According to the neural network function, the controller further determines an output parameter, indicative of the vehicle maneuvering state, by subjecting the mean value and variance of the vehicle driving parameters and the weighted total sum of the road traffic condition parameters to nonlinear conversion. Then, it variably controls the operating characteristic of a vehicle-mounted apparatus such as a rear-wheel steering controlling unit in accordance with the output parameter, thereby variably controlling the vehicle running characteristic.

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 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. The control device includes a controller for detecting the gradient and flexure degree of a road. It further includes a controller for discriminating the road conditions by fuzzy inference in accordance with the gradient and flexure degree, and for determining the delay time or time interval between the start of the roll control for the rear portion of the vehicle body and the start of the roll control for the front portion of the vehicle body in accordance with the result of the discrimination.

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.
