Wheel suspension comprising a frame suitable for connection to a body of a vehicle and comprising a first and second wheel which together define a track width, and wherein the first wheel is connected to the frame via a first set of actuators and wherein the second wheel is connected to the frame via a second set of actuators such that by means of operating the actuators the track width is adjustable between a narrow track, characterized in that the first set of actuators overlaps in the transverse direction of the vehicle with the second set of actuators.

Suspension unit, comprising a control unit, for a utility vehicle, wherein the utility vehicle has a body floor, to which a first and a second axle are connected, wherein the utility vehicle comprises at least one vehicle seat and/or a vehicle cab that can be suspended by a suspension device relative to the body floor, wherein the vehicle seat and/or the vehicle cab is arranged substantially above the second axle seen in a vertical direction, wherein, when driving over a bump with the first axle, a value of a deflection of the first axle by the disturbance can be determined by at least one sensor, and wherein the suspension device of the vehicle seat and/or vehicle cab can be varied by the control unit before or upon driving over the disturbance with the second axle.

A vehicle behavior control apparatus includes: a variable roll stiffness device configured to change roll stiffness of a first axle being one of a front axle and a rear axle and roll stiffness of a second axle being another of the front axle and the rear axle; and a controller. The controller is configured to control the variable roll stiffness device so as to increase the roll stiffness of the first axle in accordance with a lateral acceleration in at least a low acceleration range. The controller is also configured to execute a control process of controlling the variable roll stiffness device so as to increase the roll stiffness of the second axle when the lateral acceleration increases to a high acceleration range beyond the low acceleration range, or a vehicle stability control for reducing at least one of oversteer and understeer of the vehicle is abnormal.

A roll control system for a corner module of a vehicle includes a knuckle that is coupled to a strut, positioned inside a wheel, and movable in upward and downward directions, a stopper that selectively moves in a downward direction and limits a range that the knuckle moves in the upward and downward directions, a power transmission unit that transmits power for moving the stopper in the downward direction, a clutch connected to the power transmission unit for transmitting a rotational force to the power transmission as a control motor is driven, and a controller electrically connected to the control motor for transmitting a power transmission signal to the control motor to control the stopper to selectively move in the upward and downward directions.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping characteristic. The system also includes a controller coupled to each adjustable shock absorber to adjust the damping characteristic of each adjustable shock absorber, and a user interface coupled to the controller and accessible to a driver of the vehicle.
