Abstract

A steering system with a steering adjustment unit, based on the “steer by wire” concept, with an additional system for an automatic emergency stopping maneuver is provided. In situations that cannot be controlled by the driver, preset data from a preset or storage arrangement are transmitted to a braking system and a steering adjustment unit, with the vehicle then being braked and steered according to the preset data.

Claims

1-7. -7. (canceled)

8. A steering system for a non-railborne motor vehicle which a motor-driving steering adjustment unit which controls steerable vehicle wheels and is actuated by a steering control arrangement on the basis of a comparison between actual steering angle signals from an actual value transmittal actuated with the steerable vehicle wheels and nominal steering angle signals from a nominal value preset unit,

wherein the vehicle includes a system for automatic braking intervention, a system for recognizing driving conditions beyond a driver'"'"'s control and preset or storage arrangement with preset data for an emergency stopping maneuver, and

wherein the steering adjustment unit and the system for automatic braking interventions follow the preset data.

9. The steering system according to claim 8, wherein the preset data are constantly updated by sensors which sense operating and path conditions.

10. The steering system according to claim 9, wherein the sensors can detect obstacles and/or other vehicles.

11. The steering system according to claim 9, wherein the sensor systems includes a navigation system which provides data on a particular section of the path ahead.

12. The steering system according to claim 8, wherein the system for recognizing driving conditions beyond the driver'"'"'s control can detect loss of consciousness of a driver.

13. The steering system according to claim 8, wherein the preset or storage arrangement becomes active when there is a break in a signal path between the steering adjustment unit and the steering control arrangement.

14. The steering system according to claim 8, wherein the preset or storage arrangement contains only command data for an emergency stopping path.

15. A motor vehicle, comprising:

a motor-driven steering adjustment unit, which controls steerable vehicle wheels;

a steering control arrangement, which actuates the motor-driven steering adjustment unit on the basis of a comparison between actual steering angle signals from an actual valve transmitter actuated with the steerable vehicle wheels and nominal steering angle signals from a nominal value preset unit;

a system for automatic braking intervention;

a system for recognizing driving conditions beyond a driver'"'"'s control; and

a storage arrangement, which stores preset data for an emergency stopping maneuver.

wherein the steering adjustment unit and the system for automatic braking interventions follow the preset data.

16. The steering system according to claim 15, wherein the preset data are constantly updated by sensors which sense operating and path conditions.

17. The steering system according to claim 16, wherein the sensors can detect obstacles and/or other vehicles.

18. The steering system according to claim 16, wherein the sensor systems includes a navigation system which provides data on a particular section of the path ahead.

19. The steering system according to claim 15, wherein the system for recognizing driving conditions beyond the driver'"'"'s control can detect loss of consciousness of a driver.

20. The steering system according to claim 15, wherein the preset or storage arrangement becomes active when there is a break in a signal path between the steering adjustment unit and the steering control arrangement.

21. The steering system according to claim 15, wherein the preset or storage arrangement contains only command data for an emergency stopping path.
