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 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 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.
