摘要： A vehicle suspension comprises dampers changeable between low and high damping modes and normally operated in the low damping mode. A damper control stores a plurality of sets of reference numbers as a function of vehicle velocity, the reference numbers of each set representing limit values of throttle velocity for the low damping mode for a given transmission gear mode. The reference numbers of each set increase in value with increasing vehicle velocity in a continuously non-linear manner so as to compensate for the decreasing acceleration and body lift produced by a given throttle velocity as vehicle velocity increases. The control changes the damper from low to high damping during vehicle acceleration for a predetermined time when the throtle velocity exceeds a throttle velocity limit reference derived from the reference number corresponding to the vehicle velocity in the set corresponding to the selected transmission gear mode. The control further changes the dampers from low to high damping for a predetermined time when vehicle deceleration exceeds a reference, when a transmission shift occurs or when engine torque first exceeds a reference.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase or decrease vehicle height in response to the hydraulic pressure within its working fluid chamber. The hydraulic pressures within the working fluid chambers are controlled to their desired pressure by associated pressure control devices. A desired pressure computing device is further provided. The computing device calculates the actual values of roll, pitch, heave and warp of a vehicle body from the vehicle heights detected by detecting devices and calculates the differences between the actual values and the associated values of roll, pitch, heave and warp determined by a desired attitude of the vehicle body to compute the desired pressures for the actuators. The degrees of the roll and/or pitch differences are set to be higher than that of the warp difference in contributing to the determination of the desired pressures.

摘要： A feedback control system for controlling the wheel slip of a vehicle having at least one of a plurality of wheels coupled to an internal combustion engine. An engine feedback control system and suspension feedback control system operate concurrently. The suspension feedback control system includes a plurality of hydraulic actuators each coupled to one of the wheels and each responsive to a separate command signal. In response to a detection of wheel slip, the suspension feedback control system applies both a downward normal force and lateral cornering force (unless the vehicle is traveling in a straight line) to each of the wheels. The engine feedback control system is responsive to a measurement of intake manifold pressure which is a predictor of engine torque output before it occurs. Accordingly, the engine feedback control system promptly reduces engine torque output during slip conditions for improving vehicular stability.

摘要： A vehicle suspension includes a variable damping effectiveness type shock absorber, which has an actuator and according to selective actuation thereof can be set to first, second, or third conditions which respectively cause the shock absorber to provide minimum, medium, or maximum damping effect. A control system for this suspension includes: a means for detecting one or more parameters relating to the operational condition of the vehicle and for outputting information signals representative thereof; a means for being manually controlled by an operator and for selecting between first manual, second manual, and auto operational modes; and a control means for: when the manual selecting means is selecting the first manual mode, actuating the actuator to its first condition; when the manual selecting means is selecting the second manual mode, actuating the actuator to its second condition; and, when the manual selecting means is selecting the auto operational mode, actuating the actuator to one of a set of its conditions including its first condition and its third condition according to the information signals outputted by the detecting means. The vehicle operational parameters may include steering angle and vehicle speed which can cause body roll, jerk and sharp acceleration which can cause vehicle squat, braking which can cause vehicle nose diving, and vehicle shift-offable state which can cause starting squat and tail lift; and this selective increase of shock absorber damping effect when these parameters take on troublesome values prevents these problems.

摘要： A suspension control system includes an actuator which adjusts the damping or shock absorbing characteristics of the suspension system among a plurality of predetermined characteristics. Occurrences of actuation of the actuator are counted and the count is compared with a given value to gain a measure of secular variation of the suspension system. When the count exceeds the given value, a reference value used by the suspension control system is adjusted to compensate for secular variation of the suspension system. With this arrangement, the suspension controlling characteristics can be fitted to the condition of the suspension system even after secular variation.

摘要： A variable electrical resistance device for monitoring displacement of a mechanical component such as a vehicle road wheel suspension system having a housing; an electrically resistive track and conductive slip ring on a support in the housing; electrically conductive wipers on a rotatable carrier provided with a spindle for coupling to the component. The wipers traverse the resistive track and the slip ring respectively. The support is mounted on springs or flat strips of resilient metal, so as to be displaceable away from and towards the wipers. A solenoid, of double-acting type or acting in association with the bias of the springs, has an armature operating to effect displacement of the support away from and towards the wiper whereby contact between the wiper and track may be broken, or the contact pressure therebetween reduced, when monitoring is not required, thereby prolonging the life of the wiper and track assembly.

摘要： A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.
