摘要： A method for estimating damping characteristics of shock absorbers in an active or semi-active suspension involves providing a reference model of a nominal relation between a road severity index related to vertical acceleration values, and the mean driving current of the control valves of the shock absorbers, acquiring respective relative acceleration or speed data of at least the front wheels of the vehicle with respect to the vehicle body, determining a value of the road severity index starting from relative acceleration or speed data of the front wheels of the vehicle with respect to the vehicle body, acquiring values representative of the mean driving current of the control valve of each shock absorber, comparing acquired value of the mean driving current with an expected value of the nominal mean driving current determined as a function of the road severity index according to the reference model, and determining a degradation condition if the acquired value does not correspond to the expected value.

摘要： A controller estimates a state of a vehicle based on a wheel speed sensor provided on the vehicle, and outputs a control signal to a shock absorber provided between a wheel and a vehicle body according to the estimated state of the vehicle. The controller uses information of a sensor of an in-vehicle apparatus other than an apparatus dedicated to the shock absorber as an observed value in the estimation of the state of the vehicle. In other words, the controller uses sensor information of a navigation apparatus corresponding to the in-vehicle apparatus other than the shock absorber, more specifically, gyro information meaning information of a gyro sensor mounted on the navigation apparatus as the observed value in the estimation of the state of the vehicle.

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.
