Abstract

A method for operating a vehicle having a collision avoidance system including a sensor for sensing potential other parties to a collision and having an evaluator, connected to a control unit, for evaluating a risk of a collision. It is proposed that when the other party to a collision comes relatively close in the lateral direction, an actuator system is activated in order to predefine a setpoint trajectory of the vehicle in order to avoid a lateral collision. In addition, a device for operating the method is provided.

Claims

1-13. -13. (canceled)

14. A method for operating a vehicle having a collision avoidance system including a sensor for sensing a potential other party to a collision and having an evaluator, connected to a control unit, for evaluating a risk of a collision,

wherein, when the other party to a collision comes relatively close in a lateral direction, an actuator system is activated to predefine a setpoint trajectory of the vehicle to avoid a lateral collision.

15. The method as claimed in claim 14, wherein the setpoint trajectory is implemented by a braking intervention at wheel brakes.

16. The method as claimed in claim 15, wherein at low driving speeds the wheel brakes are selectively actuated with low braking pressures.

17. The method as claimed in claim 15, wherein the setpoint trajectory is further implemented by actuating a vehicle steering system.

18. The method as claimed in claim 17, wherein actuation of the wheel brakes is given priority over actuation of the vehicle steering system.

19. The method as claimed in claim 14, wherein at least one of a vehicle suspension system and a suspension system for actively influencing a wheel load distribution is actuated.

20. The method as claimed in claim 14, wherein at least one of an activation of the actuator system and an intervention by the actuator system is aborted by an intervention by the vehicle driver.

21. The method as claimed in claim 14, wherein an intervention time of the actuator system is determined as a function of a lateral relative speed.

22. The method as claimed in claim 21, wherein, in order to define the intervention time, a minimum distance from the potential other party to a collision is defined.

23. The method as claimed in claim 21, wherein a negative lateral approach speed of the potential other party to a collision is selected as a threshold value for defining the intervention time.

24. The method as claimed in claim 21, wherein at least one of an information function and a warning function is activated before the intervention time of the actuator system.

25. The method as claimed in claim 21, wherein at least one passive safety function is activated at the intervention time of the actuator system.

26. The method as claimed in claim 15, wherein at least one of a vehicle suspension system and a suspension system for actively influencing a wheel load distribution is actuated.

27. The method as claimed in claim 15, wherein at least one of the activation of the actuator system and an intervention by the actuator system is aborted by an intervention by the vehicle driver.

28. The method as claimed in claim 15, wherein an intervention time of the actuator system is determined as a function of a lateral relative speed.

29. The method as claimed in claim 22, wherein a negative lateral approach speed of the potential other party to a collision is selected as a threshold value for defining the intervention time.

30. The method as claimed in claim 22, wherein at least one of an information function and a warning function is activated before the intervention time of the actuator system.

31. The method as claimed in claim 22, wherein at least one passive safety function is activated at the intervention time of the actuator system.

32. A method for operating a vehicle having a collision avoidance system, the method comprising:

sensing a potential other party to a collision;

evaluating a risk of a collision between the vehicle and the other party; and

activating an actuator system to predefine a setpoint trajectory of the vehicle to avoid a lateral collision, if the other party to a collision comes relatively close in a lateral direction.

33. A device for operating a vehicle having a collision avoidance system comprising:

a sensor for sensing a potential other party to a collision;

an evaluator for evaluating a risk of a collision; and

an actuator system that is activatable to predefine a setpoint trajectory to avoid a lateral collision, if the other party to a collision comes relatively close in a lateral direction.
