Abstract

A method of operating a motor vehicle with a chassis system comprising at least two, preferably four vibration damper includes carrying out a body control and a wheel control with the chassis system, and controlling the energy supply for the chassis system via an energy control arrangement. A motor vehicle performing the method is also disclosed.

First claim

The invention claimed is:

1. A method of operating a motor vehicle ( 1 ) with a chassis system ( 6 ) having at least two vibration dampers ( 2 , 3 , 4 , 5 ), the method comprising the following steps:
carrying out a body control and a wheel control with the chassis system ( 6 );
providing an energy control arrangement;
controlling the energy supply for the chassis system ( 6 ) with the energy control arrangement ( 7 );
predetermining a maximum value for a peak load of the energy supply; predetermining a maximum value for a continuous load of the energy supply;
using a value between 400 W and 600 W as the maximum value for the peak load of the energy supply; and/or
using a value between 100 W and 300 W as the maximum value for the continuous load of the energy supply.

2. The method according to claim 1 , wherein the energy consumption of the chassis system is limited.

3. The method according to claim 1 , comprising distributing the available energy amount ( 10 , 20 ) when the energy requirement ( 12 , 14 , 16 ) of the chassis system ( 6 ) exceeds an available energy amount ( 10 , 20 ) or a maximum value.

4. The method according to claim 1 , comprising making available an available energy amount ( 10 , 20 ) first for the wheel control and then for the body control.

5. The method according to claim 1 , comprising using, on the average, of an available energy 5% to 15% for the wheel control and 95% to 85 % for the body control.

6. The method according to claim 1 , comprising carrying out the body control and the wheel control in the vibration dampers by different mechanisms.

7. The method according to claim 1 , comprising accomplishing a redistribution of the energy supply from the wheel control to the body control, or vice versa, continuously or quasi-continuously.

8. The method according to claim 1 , comprising carrying out a distribution of the energy supply to the wheel control and the body control depending on a storage condition of at least one energy storage ( 8 ).

9. The method according to claim 1 , comprising carrying out a distribution of the energy supply to the wheel control and the body control depending on at least one operating state of the motor vehicle ( 1 ).

10. The method according to claim 1 , comprising carrying out the body control and the wheel control by the vibration dampers ( 2 , 3 , 4 , 5 ).

11. A motor vehicle ( 1 )comprising a chassis system ( 6 ) for carrying out a body control and a wheel control, and an energy control arrangement ( 7 ) for controlling the energy supply to the body control and the wheel control, and wherein the energy control arrangement ( 7 ) is configured for implementation of the method according to claim 1 .

12. The method according to claim 1 , comprising using a value of 500 W as a maximum value for the peak load.

13. The method according to claim 1 , comprising using a value of 200 W as a maximum value for the continuous load.

14. The method according to claim 1 , comprising using, on the average, of the available energy 10% for the wheel control and 90% for the body control.
