摘要： Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments, the ride height sensing system includes a self-calibration system including at least one Hall effect sensor mounted at a fixed distance and orientation with respect to the electromagnetic source to provide for continuous calibration of the system. In one embodiment, the enhanced ride height sensing system includes at least two inertial measurement units, such as accelerometers mounted to each of the body frame of the vehicle and the axle frame of the vehicle. This enables the system to optimize power usage by more accurately and efficiently measuring the ride height at high frequency rates with relatively lower power consumption.

摘要： A ride leveler system in vehicles with an adjustable wheel suspension device between a vehicle wheel and the vehicle body, with a height sensor for measuring the actual height between the vehicle wheel and the vehicle body, and with an electronic control device which specifies a target height and adjusts the wheel suspension device until the attainment of the target height. If there is a deviation between target and actual height, the electronic control device adjusts the wheel suspension device for a minimum period of time independent of the course of the actual height. Following expiration of the minimum control time, the adjustment is switched off at a point in time at which the measured actual height has attained the value of the target height for the first time.

摘要： This invention relates to hydraulic suspension systems and in particular to vehicle oleopneumatic suspension systems employing sliding pillar struts. There is provided a suspension system for a vehicle comprising a plurality of suspension struts, each mounted between a vehicle body and a wheel assembly, each including a cylinder having a closed end and an inner bore; a piston rod slideable within the inner bore having a proximal end which terminates within the inner bore and a distal end which extends from the inner bore. Between the inner bore and the piston rod there is mounted an oil seal which seals a strut volume. A hydrostatic bearing is mounted within and vents into the strut volume. A hydraulic circuit and associated control system is adapted to control flow of hydraulic fluid between the strut volume and a reservoir, thereby providing control of at least the time-averaged axial position of the piston rod relative to its corresponding inner bore.

摘要： In an apparatus and method for a vehicular system, a control gain of a control signal to be outputted to the vehicular system is varied when a change in a weight of load applied to a vehicle body between an originally designed weight of load applied to a vehicle body and a present weight of load applied to the vehicle body occurs. The change in the weight of load applied to the vehicle body is determined according to a load mounted state determination signal R.sub.M which is derived on the basis of a front road wheel side vertical status variable and a rear road wheel side vertical status variable.
