The disclosure relates to a coupling device for a stabilizer of a suspension. The coupling device has a first coupling portion and a second coupling portion that is supported thereon. One coupling portion has a connection location for the stabilizer and another coupling portion has a connection location for a wheel suspension. and the coupling device also has a locking device, which, in a locking position, limits a relative movement of the second coupling portion with respect to the first coupling portion in a first direction. In order to better protect a stabilizer from overload, the locking device is configured in a release position to release the relative movement when a first force acting between the connection locations exceeds a threshold value.

An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit includes a first leveling valve configured to adjust independently the height of a first side of the vehicle. The second pneumatic circuit includes a second leveling valve configured to adjust independently the height of a second side of the vehicle. The first and second leveling valves are configured to establish pneumatic communication between the first and second pneumatic circuits when the first leveling valve is not independently adjusting the height of the first side of the vehicle and the second leveling valve is not independently adjusting the height of the second side of the vehicle.

An improved adaptive stabilizer bar is provided. The stabilizer bar includes a cycloidal drive between first and second portions of a divided torsion bar. The cycloidal drive includes a cycloidal gear assembly that provides a significant mechanical advantage, allowing relatively small electric motors to be used. In addition, the cycloidal gear assembly has a relatively small physical footprint, particularly when compared to a planetary gear assembly, for example.

A passenger vehicle provided with a steering handle (15) and configured such that an attitude angle of the driver seat surface (14a) relative to a horizontal reference plane is changeable, so that a first attitude changing operation switch (25) and a second attitude changing operation switch (26) for changing the attitude angle are disposed in such positions as to be operable with a thumb of the driver of the vehicle from a steering handle grip (18) of the steering handle (15).

A method and apparatus for providing an off-road feature of a vehicle includes determining that the vehicle is in an off-road area based upon a location of the vehicle and sensed terrain characteristics at the location. Upon determining that the vehicle is in the off-road area, the vehicle monitors parameters for enablement of the off-road feature of the vehicle. The off-road feature is enabled in response to the parameters being within a predetermined range based upon a number of transitions between an enabled state and a disabled state within a predetermined time being less than a transition threshold. Parameter monitoring for enablement of the off-road feature is ceased upon determining that the vehicle has moved from the off-road area to an on-road area.

A system for controlling an active stabilizer bar in a vehicle includes a stabilizer bar associated with one or more wheels of the vehicle and a control module in communication with the stabilizer bar. The stabilizer bar is configured to be controlled according to a plurality of stiffness modes. Each stiffness mode is associated with a different amount of torque for the stabilizer bar. The control module is configured to control the stabilizer bar to operate according to a first stiffness mode of the plurality of stiffness modes, detect an anomaly in a path of the vehicle, and in response to detecting the anomaly, control the stabilizer bar to operate according to a second stiffness mode of the plurality of stiffness modes, the second stiffness mode being different than the first stiffness mode. Other examples systems and methods for controlling active stabilizer bars in vehicles are also disclosed.
