Abstract
A method is provided for a preventive-action protection system in a motor vehicle having an inter-vehicle distance sensor system and having safety devices for lessening the consequences of accidents, wherein driving state data is acquired by means of a driving state sensor system and is monitored, in evaluation stages, with respect to critical states of vehicle movement dynamics (emergency braking, understeering, oversteering, rolling over). As a further triggering condition, a speed threshold has to be exceeded by the vehicle's own speed or preferably by the relative speed measured by the inter-vehicle distance sensor system.

A method for a preventive-action protection system in a motor vehicle having safety devices for lessening the consequences of accidents, the method comprising the acts of:
- acquiring driving state data by a driving state sensor system;
- monitoring, in evaluation stages, the acquired driving state data with respect to critical states of vehicle movement dynamics;
- and
- triggering at least one of the safety devices when a critical state of vehicle movement dynamics is determined and in a further triggering condition a speed threshold is exceeded by the vehicle's own speed,
- wherein when the vehicle detects an imminent impact by means of an inter-vehicle distance sensor system and determines a relative speed in relation to a collision object, and at the same time a critical state of a vehicle movement dynamics is sensed, the further triggering condition is replaced by a condition in which a speed threshold has to be exceeded by the relative speed for at least one of the safety devices to be triggered.
