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. It implements fuzzy inference based on a traveling time ratio, an average speed, and an average lateral acceleration, which are obtained from vehicle speed and/or steering angle, to thereby calculate road traffic condition parameters, including a city area degree, a jammed road degree, and a mountainous road degree. 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： 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.
