Title: Vehicle pneumatic levelling suspension with activation of parking brake
Inventor: MEIER JOERG
IPC: B60T8/00
Filed: 1996-11-21
Abstract: The vehicle is fitted with pneumatic suspension elements on each wheel and with a parking brake acting on each axle. The parking brake is lifted on one axle during manual adjustment of the suspension. This reduces mechanical stress. If the vehicle starts to roll, after release of one parking brake, the suspension adjustment is blocked and the full parking brake action is restored. The suspension control has sensors to monitor the actual spacing between the suspension and the vehicle and compare same with the selected values. The vehicle movement is detected by other sensors, which can include the ABS sensors.

Title: Screen communication system linking vehicle with service station or garage
Inventor: MEHRING ULRICH
IPC: G07C5/00
Filed: 1996-12-03
Abstract: The system consists of a screen and input system in the vehicle so that the driver can key into the display full information about any fault. This information is then transmitted to the chosen garage for determination of the source of the problem and preparation for repair. A dialogue between the driver and the service station can be built-up through the medium of the screen. In addition, by means of a navigation system, the exact location of the vehicle can be determined and the nearest repair station located. The use of a screen display and wireless communication system enables the garage to diagnose the fault more accurately and quickly, so that appropriate preparations for its repair on arrival can be made.
