    摘要: A method and apparatus for controlling frame rise on a heavy duty truck having a frame, a drive axle connected to the frame, and a selectively lockable suspension component disposed therebetween for maintaining the relative position therebetween. Signals indicative of at least one of the following vehicle operating parameters: engine speed, brake pressure, vehicle speed, air bag pressure, steering wheel angle, vehicle height, or throttle position are monitored and a predicted thrust is calculated that will be applied to the drive axle based on the monitored signals. The selectively lockable suspension component is locked if the predicted thrust exceeds a predetermined threshold and is also controlled with respect to other operating parameters such as whether vehicle brakes are applied, any instantaneous change in torque, vehicle operating speed, and the length of time the selectively lockable suspension component has been locked.

    摘要: Vehicle speed is measured and used to calculate lateral acceleration of the vehicle and speed dependent thresholds to which the lateral acceleration of the vehicle is compared to determine when to change a controllable suspension system of the vehicle to improve operation of the suspension system. The controllable suspension system includes air springs and variable damping shock absorbers switchable between soft and firm damping rates. At speeds above a given speed, lateral accelerations exceeding first speed dependent thresholds will result in switching the shock absorbers to firm and/or closing gate valves which intercouple the left and right air springs to decrease vehicle roll. For slower speeds less than the given speed, the suspension system control is desensitized such that lateral accelerations of the same given magnitudes, for example due to entering a parking space or other low speed maneuver, do not alter the suspension. Switch back of shock absorbers from firm to soft and opening of the gate valves can be based on expiration of an elapsed time period or detection of the lateral acceleration of the vehicle falling below second speed determined thresholds.

    摘要: An electronically controlled fluid suspension system detects an average longitudinal or lateral acceleration within a predetermined period, computes an acceleration difference between a maximum average acceleration and a minimum average acceleration. Based on the acceleration difference, an estimated longitudinal or lateral acceleration is computed. In response to the estimated longitudinal or lateral acceleration, computed are a height-raising quantity of a lowered portion of a vehicle and a height-lowering quantity of a raised portion thereof. The supply and release of a fluid to and from fluid springs is rapidly controlled so that the height-raising quantity of the lowered portion of the vehicle is less than the height-lowering quantity of the raised portion thereof. The electronically controlled fluid suspension system, thus, prevents the vehicle from inclining due to changes in driving status, and enhances a road-adherence ability on an uneven road as well as a steering stability.
