Abstract: An in-vehicle device in a vehicle transmits a request signal and a portable device returns a response signal including an ID code. The in-vehicle device collates the ID code included in the response signal with a registration code stored therein. When the result of collating the ID code becomes OK, the in-vehicle device outputs a height decreasing signal to a vehicle height control device to decrease the height of the vehicle. Thus, the height of the vehicle is decreased at the time when a user holding the portable device gets in the vehicle or loads baggage, making it easier for users to get in the vehicle or to load baggage.

Abstract: A level control system controls the distance between the vehicle axles and the vehicle frame of a vehicle. The suspension is a full or partial air suspension, wherein the vehicle frame over the vehicle axles is supported via air suspension bellows. A vehicle inclination, i.e. a non-parallel alignment between vehicle frame and one or more of vehicle axles may occur as a result of various situations which may be dramatically different from one another. Uneven support of the vehicle represents one cause of vehicle inclination, for example, when one wheel of a vehicle axle is standing on the sidewalk. In order to avoid air losses, a vehicle level is not compensated for while the vehicle is stopped. Instead, the existing inclination is maintained and is entered into the control system as a target level. All level changes which occur due to changes in the load of the vehicle are compensated for by means of this prescribed target value.
