摘要： Suspension mechanisms for motor vehicles include dampers of variable damping powers and air springs of variable spring coefficients so that the suspension characteristics are changed between soft and hard modes. The suspension mechanisms are provided with a controller for producing a control signal only when the differential value between the value of a last steering angle and an average value of steering angles is larger than a predetermined value to change the suspension characteristics to the hard mode. In accordance with this arrangement, the suspension characteristics are changed to the hard mode only when the rolling angle of the vehicle exceeds a predetermined value.

摘要： A method and system for controlling a vehicle suspension system switchable between two modes of operation, including a first mode for when the vehicle is experiencing an on-road driving condition and a second mode for when the vehicle is experiencing an off-road driving condition, includes a vehicle speed sensor for sensing a speed of the vehicle and generating a vehicle speed signal, which may be an inherent part of the vehicle required for other vehicle functions, such as ABS, speed, or other control. The system also includes a controller for detecting an off-road driving condition and comparing the vehicle speed signal to a predetermined speed threshold. The controller then controls the suspension system to switch to the second mode of operation upon detecting the off-road driving condition and the vehicle speed signal being less than the predetermined speed threshold.

摘要： An apparatus for estimating a road traffic condition and for controlling a vehicle running characteristic includes a controller having a fuzzy inference function and a neural network function. The controller carries out frequency analysis on vehicle driving parameters such as vehicle speed, steering angle, accelerator opening degree, 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： A wheel alignment control method for a motor vehicle and a control apparatus therefor in which every time a vehicle drive state, steering history, and high-speed steering-hold mode are discriminated by sensor outputs, a processor determines target values of a caster angle, camber angle, and toe angle in accordance with inference outputs computed by fuzzy inference based on fuzzy rules, corresponding individually to a plurality of vehicle drive modes, steering modes, and high-speed steering-hold mode, and discrimination results. Operating sections adjust the camber and the like by means of a driver circuit which responds to the processor outputs. Thus, a fine adjustment for alignment is made, and wheel alignment adaptable to the vehicle drive modes and the like is established.

摘要： An apparatus for controlling a suspension system disposed between a wheel and a body of an automotive vehicle, has a device for adjusting a response of the suspension system to mechanical excitations transmitted by the body and/or the wheels. A first controller is sensitive to a vertical speed and a vertical acceleration of the vehicle body, for developing a first virtual control signal of the adjusting device which is suitable for optimizing a ride of the vehicle. A second controller is sensitive to a deflection of the wheel and a vertical speed of the wheel relative to the ground, for developing a second virtual control signal of the adjusting device which is suitable for optimizing contact between the wheel and the ground. A supervising device is sensitive to the first and second virtual control signals for developing a real control signal which is applied to the adjusting device for adjusting the response of the suspension system as a function of a predetermined behavior strategy.
