Method and device for actuating a passenger protection means
First Claim
1. A method for actuating a vehicle occupant protection system in a vehicle having a sensor system that senses driving state data and a reversible vehicle occupant protection system that is moveable into an effective position before a collision occurs;
- said method comprising;
a predictive surroundings sensing unit determining a setpoint braking deceleration that triggers a movement of the vehicle occupant protection system into the effective position in advance of an imminent collision when said setpoint braking deceleration exceeds a threshold value; and
checking to determine whether the setpoint braking deceleration exceeds said threshold value, by referring to a deceleration characteristic curve that varies with vehicle speed.

Abstract
In a method for actuating a vehicle occupant protection system, a sensor senses driving state data, and a reversible vehicle occupant protection device can be triggered to move into an effective position, prior to an imminent collision. A setpoint braking deceleration, which triggers the vehicle occupant protection device when a threshold value is exceeded, is determined by a predictive surroundings sensing unit in advance of an imminent collision. A check is made to determine whether the setpoint braking deceleration exceeds a threshold value, by referring to a deceleration characteristic curve that is dependent on the vehicle speed.

16. Apparatus for actuating a vehicle occupant protection system having a sensor system that senses driving state data, and a reversible vehicle occupant protection system that is moveable into an effective position before the occurrence of an imminent collision, wherein a setpoint braking deceleration that triggers a movement of the vehicle occupant protection system into the effective position when said setpoint braking deceleration exceeds a threshold value is determined by a predictive surroundings sensing unit in advance of an imminent collision, and checking is carried out to determine whether the setpoint braking deceleration exceeds said threshold value, by referring to a deceleration characteristic curve which is dependent on the vehicle speed, said apparatus comprising:
-
a vehicle occupant protection device; and a control unit which uses a requested braking deceleration to check for the presence of a critical driving state by referring to a deceleration characteristic curve that is dependent on the vehicle speed; wherein the vehicle occupant protection system is activated in response to presence of the critical driving state.
