Method for actuating a reversible vehicle occupant protection means in a motor vehicle
First Claim
1. A method for actuating a reversible protection system in a motor vehicle having a sensor system and a reversible protection system which can be triggered before a collision and, as a result, moved into an effective position, comprising:
- monitoring a first control signal of a brake boosting system and a second control signal of a brake light switch with the sensor system,setting a longitudinal protection signal to an active state when an emergency braking operation, existing when both the first control signal and the second control signal are active, is detected, andtriggering the reversible protection system when the emergency braking operation is detected.

Abstract
The invention relates to a method for actuating a reversible vehicle occupant protection means in a motor vehicle having a driving state sensor system and a reversible vehicle occupant protection means. The reversible vehicle occupant protection means can be triggered before the collision time and as a result moved into an effective position. For this purpose, the driving state data are monitored with respect to a state of emergency braking, and when the state of emergency braking is detected the vehicle occupant protection system is actuated. In addition, a state of oversteering and a state of understeering are determined by the data processing device. The reversible vehicle occupant protection system is actuated when the data processing device detects the state of emergency braking and/or the state of oversteering and/or the state of understeering.

13. A method for actuating a reversible vehicle occupant protection means, in a motor vehicle having a sensor system which senses driving state data, before a collision time and, as a result, moving the vehicle occupant protection system into an effective position, comprising:
-
monitoring the driving state data with respect to understeering, which is critical for driving dynamics, and triggering the vehicle occupant protection system when the understeering, which is critical for driving dynamics, is detected, wherein the state of understeering is determined by means of an evaluation of the difference formed between an angle which describes a change in the actual direction of travel, and the steering angle, wherein the angle which describes a change in the actual direction of travel is the Ackermann angle, and wherein the state of understeering is monitored by means of two separate algorithms which are each based on different calculations of the Ackermann angle, and the results of the two algorithms are logically linked.
