A method for a safety system in a vehicle continuously evaluates data relating to the surroundings from a surroundings sensor system in terms of an imminent collision with an obstacle, and autonomous emergency braking is initiated in the event of an unavoidable collision. The emergency braking is maintained until a predefined event occurs. The predefined event can be the expiration of a time calculated in advance up to the collision or the impact which is actually detected by a sensor.

1. A method for a safety system in a vehicle, comprising continuously evaluating data relating to the surroundings from a surroundings sensor system in terms of an imminent collision with an obstacle, initiating autonomous emergency braking in the event of an unavoidable collision, and maintaining the emergency braking until a predefined event occurs, wherein the emergency braking is maintained up to a collision time that is calculated in advance from the surroundings data, whereupon a brake is then opened. 2. The method as claimed in claim 1, wherein the emergency braking is aborted if the collision does not occur within a predetermined time window after the collision time that is calculated in advance from the data relating to the surroundings. 3. The method as claimed in claim 2, wherein the predetermined time window is about 50 ms. 4. The method as claimed in claim 2, wherein upon occurrence of the collision, the emergency braking is maintained until the end of the collision is inferred from acceleration sensor signals. 5. The method as claimed in claim 4, wherein, after the termination of the emergency braking, a braking effect which is reduced compared to the emergency braking is continued if an impact with a high degree of severity in terms of an accident has been detected. 6. The method as claimed in claim 2, wherein upon occurrence of the collision, the emergency braking is maintained for a predefined time period after the collision. 7. The method as claimed in claim 6, wherein, after the termination of the emergency braking, a braking effect which is reduced compared to the emergency braking is continued if an impact with a high degree of severity in terms of an accident has been detected. 8. The method as claimed in claim 2, wherein the occurrence of the collision is detected by at least one of a contact sensor system, exported acceleration sensors or deformation sensors and an airbag control unit acceleration sensor. 9. The method as claimed in claim 8, wherein upon occurrence of the collision, the emergency braking is maintained until the end of the collision is inferred from acceleration sensor signals. 10. The method as claimed in claim 8, wherein upon occurrence of the collision, the emergency braking is maintained for a predefined time period after the collision. 11. The method as claimed in claim 10, wherein emergency braking is suppressed or is carried out only with a reduced braking effect if at least one of a driving situation which is critical in terms of vehicle movement dynamics. 12. The method as claimed in claim 11, wherein the critical driving situation is critical in terms of lateral dynamics. 13. The method as claimed in claim 1, wherein the emergency braking is suppressed or is carried out only with a reduced braking effect if not all vehicle occupants are deemed secured by a seatbelt. 14. The method as claimed in claim 1, wherein at the same time as the emergency braking occurs, reversible protection measures are activated. 15. The method as claim in claim 14, wherein one of the measures is a reversible seat belt pretensioner.
