Abstract

A method and system for preventing a following vehicle from driving up on a vehicle driving directly in front. The following vehicle detects a behavior of the vehicle driving directly in front by sensor information and a behavior of at least one vehicle driving in front by vehicle-to-X information. The vehicle-to-x information requests an intervention in the steering of the following vehicle by a steering angle to be set and/or an intervention in the braking of the following vehicle by a deceleration to be set in order to prevent driving up on the vehicle, and wherein the steering angle and/or the deceleration requested by the vehicle-to-X information is greater than a steering angle and/or a requested deceleration requested by the sensor information and/or driver inputs. The intervention is only carried out if the steering angle and/or the deceleration is confirmed by sensor information and/or driver inputs.

Claims

1. A method for preventing a following vehicle from driving up on a vehicle driving directly in front, in which the following vehicle detects a behavior of the vehicle driving directly in front by sensor information and a behavior of at least one vehicle driving in front of the vehicle driving in front by means of vehicle-to-X information, wherein the vehicle-to-X information requests an intervention in steering means of the following vehicle in the form of a steering angle to be set and/or an intervention in braking means of the following vehicle in the form of a deceleration to be set in order to prevent the rear-end collision with the vehicle, and wherein the steering angle requested by the vehicle-to-X information and/or the requested deceleration is greater than a steering angle requested by the sensor information and/or driver inputs and or a requested deceleration, wherein the intervention with the steering angle requested by the vehicle-to-X information and/or the requested deceleration is/are performed only if this steering angle and/or this deceleration is/are confirmed by the driver inputs.

2. The method as claimed in claim 1,

wherein the steering angle requested by the vehicle-to-X information and/or the requested deceleration is/are confirmed if the latter is/are less than or equal to a steering angle and/or a deceleration requested by the sensor information and/or the driver inputs.

3. The method as claimed in claim 1,

wherein the intervention is carried out with a minimum necessary steering angle for preventing the rear-end collision and/or a minimum necessary deceleration if the steering angle requested by the vehicle-to-X information and/or the requested deceleration is/are greater than the steering angle and/or the deceleration which is/are requested by the sensor information and/or the driver inputs.

4. The method as claimed in claim 3,

wherein the intervention is performed with the minimum necessary steering angle and/or the minimum necessary deceleration to prevent the rear-end collision only if the sensor information and/or the driver inputs actually request an intervention.

5. The method as claimed in claim 1,

wherein the intervention is performed at least with the steering angle requested by the sensor information and/or the driver inputs and/or the deceleration requested by the sensor information and/or the driver inputs.

6. The method as claimed in claim 5,

wherein the intervention is performed with the steering angle requested by the sensor information and/or the requested deceleration if the latter is/are greater than the steering angle and/or the deceleration which is/are requested by the driver inputs.

7. The method as claimed in claim 5,

wherein the intervention is performed with the steering angle requested by the driver inputs and/or the requested deceleration if the latter is/are greater than the steering angle and/or the deceleration which is/are requested by the sensor information.

8. The method as claimed in claim 1,

wherein no intervention is performed if only the vehicle-to-X information requests the intervention.

9. The method as claimed in at least claim 8,

wherein a visual, audible and/or haptic warning is/are output to the driver if only the vehicle-to-X information requests the intervention.

10. The method as claimed in claim 1,

wherein the behavior of the vehicle driving in front describes a deceleration of the vehicle driving in front and the behavior of the vehicle driving in front of the vehicle driving in front describes a deceleration of the vehicle driving in front of the vehicle driving in front.

15. The method as claimed in claim 2,

wherein the intervention is carried out with a minimum necessary steering angle for preventing the rear-end collision and/or a minimum necessary deceleration if the steering angle requested by the vehicle-to-X information and/or the requested deceleration is/are greater than the steering angle and/or the deceleration which is/are requested by the sensor information and/or the driver inputs.

11. A system for preventing a following vehicle from driving up on a vehicle driving directly in front, comprising the following vehicle with environment sensors, vehicle-to-X communication means, steering intervention means, braking intervention means and driver input means, furthermore comprising the vehicle driving in front and at least one vehicle driving in front of the vehicle driving in front, wherein the following vehicle detects a behavior of the vehicle driving directly in front by sensor information and a behavior of at least one vehicle driving in front of the vehicle driving in front by vehicle-to-X information, wherein the vehicle-to-X information requests an intervention in the steering means of the following vehicle in the form of a steering angle to be set and/or an intervention in the braking means of the following vehicle in the form of a deceleration to be set in order to prevent the rear-end collision and wherein the steering angle requested by the vehicle-to-X information and/or the requested deceleration is/are greater than a steering angle requested by the sensor information and/or driver inputs and/or a requested deceleration,

wherein the steering intervention means and/or the braking intervention means perform the intervention with the steering angle requested by the vehicle-to-X information and/or the requested deceleration only if the steering angle and/or the deceleration is/are confirmed by the sensor information and/or by the driver inputs.

12. The system as claimed in claim 11,

wherein the environment sensors comprise one or more sensors of the following group:

a lidar sensor,

a radar sensor,

a camera sensor, and

an ultrasound sensor.

13. The system as claimed in claim 11,

wherein the system carries out a method for preventing a following vehicle from driving up on a vehicle driving directly in front, in which the following vehicle detects a behavior of the vehicle driving directly in front by sensor information and a behavior of at least one vehicle driving in front of the vehicle driving in front by means of vehicle-to-X information, wherein the vehicle-to-X information requests an intervention in steering means of the following vehicle in the form of a steering angle to be set and/or an intervention in braking means of the following vehicle in the form of a deceleration to be set in order to prevent the rear-end collision with the vehicle, and wherein the steering angle requested by the vehicle-to-X information and/or the requested deceleration is greater than a steering angle requested by the sensor information and/or driver inputs and or a requested deceleration, wherein the intervention with the steering angle requested by the vehicle-to-X information and/or the requested deceleration is/are performed only if this steering angle and/or this deceleration is/are confirmed by the driver inputs.

14. A use of the system as claimed in claim 11 in a motor vehicle.
