A method of setting the rides height of the air springs and air pressures of the tires, including receiving a user selected setting or preprogrammed ride height settings; sensing a ride height of, and air pressure within, each of the air springs; determining the weight of the vehicle based on the sensed ride height and air pressure within each of the air springs; providing specified ride heights for the left and right front and rear air springs; determining specified air pressures for the left and right front and rear tire inflators, based upon the determined weight of the vehicle and selected setting; inflating the left and right front and rear air springs to the specified ride heights; and inflating the left and right front and rear tires to the specified air pressures.

An air suspension system for a motor vehicle and a method of operating thereof includes an air suspension device for adjusting a ride-height position of the motor vehicle by the feeding and removal of compressed air into a plurality of air springs. The system also includes a dryer supplied via a compressed-air supply unit which has a compressor driven by an electric motor. A control unit for performing a ride-height control function has instruction for: raising the ride-height position to a first ride-height position; subsequently lowering the ride-height position to a second ride-height position; checking a first condition whether a determined air quantity ratio is less than a first predetermined air quantity limit value; checking a second condition whether a saturation level of the dryer is greater than a saturation limit value, and activating the ride-height control function when either the first or the second condition is satisfied.

An additional spring for a shock absorber of a motor vehicle and a damper bearing for a shock absorber of a motor vehicle. In this case, the additional spring includes a first spring body which has a central hole for guiding through a piston rod of the shock absorber. The first spring body is formed spherical on an end face. The damper bearing according to the invention comprises a cylindrical receptacle space in which the first spring body of the additional spring is retained at least in certain regions, and is distinguished in that the receptacle space has a spherically formed base surface formed corresponding to the end face of the first spring body.

An automatic shutoff system for a motor vehicle, the automatic shutoff system including a front suspension system disposed at a front portion of the motor vehicle, the front suspension system comprising at least one spring wrapped around at least one arm, at least one sensor disposed on the at least one arm to sense when the at least one spring has been jarred at a predetermined intensity, a curb jump detection system to receive at least one signal from the at least one sensor when the at least one spring has been jarred at the predetermined intensity, and to process the at least one signal to determine whether a curb has been jumped by the front suspension system, and a computer system to receive a signal from the curb jump detection system when the curb jump detection system determines that the curb has been jumped by the front suspension system, and to control a motor to shut off.

Examples of techniques for controlling vehicle pitch while the vehicle is towing a trailer are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes detecting, by a processing device, a trailer attached to a vehicle. The method further includes responsive to detecting the trailer attached to the vehicle, detecting, by the processing device, a pitch event. The method further includes when a pitch event is detected, determining, by the processing device, whether the pitch event exceeds a pitch threshold. The method further includes, responsive to determining that the pitch event exceeds the pitch threshold, adjusting, by the processing device, a vehicle pitch control device associated with the vehicle to counteract the pitch event for the vehicle and the trailer.

An active suspension control system for a vehicle includes a mathematical model based on a modal expansion of the vehicle. Model parameters of the vehicle can be extracted from the modal expansion using sensor data generated on the vehicle, e.g., on demand and/or in real time. The model parameters and the modal expansion can be used to determine a vehicle state, predict future vehicle states, and control aspects of an active suspension system based on the predicted future vehicle states. The model parameters may also be used to update the mathematical model, e.g., to account for component wear over time, and/or to detect anomalies or defects in the active suspension system.
