A method is provided for automatically decelerating a vehicle to avoid a collision or reduce the consequences of a collision with a detected collision object, wherein, at a determined intervention point-in-time, a brake system of the vehicle is automatically triggered such that a deceleration of the vehicle is caused, and wherein an automatic deactivation of the automatic braking intervention can take place by an increased actuation of the accelerator. A deactivation is carried out as a function of an override maneuver that depends on the actual driving dynamics, particularly an actuation of the accelerator that depends on the actual driving dynamics.

1. A method of operating a driver assistance system that automatically decelerates a vehicle to avoid a collision or reduce consequences of a collision with a detected collision object, the method comprising the acts of: causing an automatic braking intervention at a determined intervention point-in-time to decelerate the vehicle; anddeactivating the automatic braking intervention based on an override maneuver dependent on actual driving dynamics of the vehicle, wherein the deactivation is carried out as a function of an actuation of the accelerator that depends on an actual deceleration of the vehicle. 2. The method according to claim 1, wherein the deactivation of the automatic braking intervention is carried out when, after the automatic braking intervention is caused, the accelerator is actuated by more than a specified first differential pedal angle dependent on the actual deceleration of the vehicle. 3. The method according to claim 2, wherein the first differential pedal angle to be exceeded for deactivating the automatic braking intervention is specified as a function of the actual deceleration of the vehicle according to at least one of the following: in a case of a slight deceleration, a slight first differential pedal angle is specified as the first differential pedal angle; andin a case of a larger deceleration, a larger first differential pedal angle than in the case of the slight deceleration is specified as the first differential pedal angle. 4. The method according to claim 3, wherein the first differential pedal angle to be exceeded for deactivating the automatic braking intervention is specified as a function of the actual deceleration of the vehicle such that, at least within a specified deceleration range, the first differential pedal angle to be exceeded becomes larger as the actual deceleration of the vehicle becomes greater. 5. The method according to claim 3, further comprising the acts of: at a determined warning point-in-time occurring before the intervention point-in-time, triggering a driver warning; andautomatically deactivating the triggered driver warning when a specified second differential pedal angle is reached or exceeded. 6. The method according to claim 5, wherein the specified second differential pedal angle for deactivating the driver warning is, at a minimum, no greater than a smallest specified first differential pedal angle for deactivating the automatic braking intervention. 7. The method according to claim 2, wherein the first differential pedal angle to be exceeded for deactivating the automatic braking intervention is specified as a function of the actual deceleration of the vehicle such that, at least within a specified deceleration range, the first differential pedal angle to be exceeded becomes larger as the actual deceleration of the vehicle becomes greater. 8. The method according to claim 7, further comprising the acts of: at a determined warning point-in-time occurring before the intervention point-in-time, triggering a driver warning; andautomatically deactivating the triggered driver warning when a specified second differential pedal angle is reached or exceeded. 9. The method according to claim 2, further comprising the acts of: at a determined warning point-in-time occurring before the intervention point-in-time, triggering a driver warning; andautomatically deactivating the triggered driver warning when a specified second differential pedal angle is reached or exceeded. 10. The method according to claim 9, wherein the specified second differential pedal angle for deactivating the driver warning is, at a minimum, no greater than a smallest specified first differential pedal angle for deactivating the automatic braking intervention. 11. The method according to claim 1, further comprising the acts of: at a determined warning point-in-time occurring before the intervention point-in-time, triggering a driver warning; andautomatically deactivating the triggered driver warning when a specified second differential pedal angle is reached or exceeded. 12. The method according to claim 11, wherein the specified second differential pedal angle for deactivating the driver warning is, at a minimum, no greater than a smallest specified first differential pedal angle for deactivating the automatic braking intervention. 13. A method of operating a driver assistance system that automatically decelerates a vehicle to avoid a collision or reduce consequences of a collision with a detected collision object, the method comprising the acts of: causing an automatic braking intervention at a determined intervention point-in-time to decelerate the vehicle; anddeactivating the automatic braking intervention based on an override maneuver dependent on actual driving dynamics of the vehicle, wherein the deactivation of the automatic braking intervention is carried out when, after the automatic braking intervention is caused, the accelerator is actuated by more than a specified first differential pedal angle dependent on an actual deceleration of the vehicle. 14. The method according to claim 13, wherein the first differential pedal angle to be exceeded for deactivating the automatic braking intervention is specified as a function of the actual deceleration of the vehicle according to at least one of the following: in a case of a slight deceleration, a slight first differential pedal angle is specified as the first differential pedal angle; andin a case of a larger deceleration, a larger first differential pedal angle than in the case of the slight deceleration is specified as the first differential pedal angle. 15. The method according to claim 13, wherein the first differential pedal angle to be exceeded for deactivating the automatic braking intervention is specified as a function of the actual deceleration of the vehicle such that, at least within a specified deceleration range, the first differential pedal angle to be exceeded becomes larger as the actual deceleration of the vehicle becomes greater. 16. The method according to claim 15, further comprising the acts of: at a determined warning point-in-time occurring before the intervention point-in-time, triggering a driver warning; andautomatically deactivating the triggered driver warning when a specified second differential pedal angle is reached or exceeded. 17. The method according to claim 16, wherein the specified second differential pedal angle for deactivating the driver warning is, at a minimum, no greater than a smallest specified first differential pedal angle for deactivating the automatic braking intervention.
