This application relates to an electronically controlled air suspension (ECAS) system. When a vehicle starts, the ECAS system receives data from a wheel height sensor and sets the received height as a default height. When driving, a high-speed line profiler scans the road surface in front of the tires of the vehicle. This information is processed by an image processing unit to determine the amount of air in the corresponding damper. If there is a bump on the road, the ECAS system may reduce the amount of air on the tire side in advance, and if there is a dip, the ECAS system may increase the amount of air on the tire side in advance to minimize vibration. Regarding the residual vibration after passing through the bump or dip, the amount of air is adjusted so that the vibration stops quickly by receiving real-time data from the wheel height sensor.

A system and methods are provided for a suspension system of an off-road vehicle that allows the springs to be mounted remotely, in any location on the vehicle, enabling the use of spring sizes, spring rates, motion ratios, and damping profiles that would be impractical with traditional suspensions. The suspension system includes a hydraulic cylinder coupled between the wheel and the chassis, in lieu of a conventional spring. This cylinder is in fluid communication with another cylinder by way of a hydraulic hose. This second cylinder includes a piston that presses against a suspension spring that is in contact with a fixed spring stop, thus transferring spring forces to the wheel. Alternatively, the spring stop may comprise a control actuator that moves according to signals from an onboard computer control system, enabling active control over spring load and chassis attitude.

Included are an electromagnetic actuator which generates drive forces for a damping operation and a telescopic operation; an information acquirer which acquires information about the drive forces of, and control mode selection information about, the electromagnetic actuator; a drive force arithmetic part which sets a predetermined control mode based on the control mode selection information about the electromagnetic actuator, and sets a target damping force and a target telescopic force of the electromagnetic actuator based on setting information about the control mode; and a drive controller which controls drive of the electromagnetic actuator using a target drive force based on the target damping and telescopic forces set by the drive force arithmetic part. The drive force arithmetic part performs an operation of switching a setting of the predetermined control mode from one to another while a driving force of the electromagnetic actuator is within a predetermined force range.

A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) has an actuator (2) which can be rotated through a system angle (α) relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b), connected thereto, relative to one another. The stabilizer sections (6a, 6b) are each a radial spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The method includes controlling the actuator with a field-orientated regulator (20) as a function of input signals which include at least a target motor torque (21), and checking the control of the actuator (2), brought about by the field-orientated regulator (20), for plausibility independently of the field-orientated regulator (20).

An adjustable suspension mount assembly includes a bracket coupled to a suspension mounting component and coupled to a frame component of the vehicle. The assembly also includes a vertical adjustment assembly operatively coupled to the bracket. The assembly further includes an electric motor operatively coupled to the vertical adjustment assembly to adjust the vertical position of the bracket.

An air spring suspension system includes a first air spring that has a first volume with a first pressure that is configured to provide a first spring stiffness to a first suspension assembly. A second air spring has a housing with a second volume with a second pressure that is configured to provide a second spring stiffness to a second suspension assembly. The second air spring includes a piston that is arranged in the second volume. One of the housing and the piston includes a first mounting structure that is configured to connect to a vehicle chassis. Another of the housing and the piston includes a second mounting structure that is configured to connect to the second suspension assembly. The second air spring also includes a fluid connection on the housing. The second air spring further includes a crosslink valve that is disposed in the housing and movable between open and closed positions. The crosslink valve is configured to selectively fluidly connect the second volume to the fluid connection. A crosslink line is fluidly connected to the first volume of the first air spring and the fluid connection on the second air spring. A controller is in communication with the crosslink valve. The controller is configured to command the crosslink valve between the open and closed positions in response to an input.
