Abstract
In a method and a device for preventively actuating a vehicle occupant protection means in a vehicle having a vehicle movement dynamics control system, the vehicle occupant protection elements can be activated before a collision time and thus placed in an operative position. An evaluation variable relating to a state of “oversteering” is monitored, and when the state of “oversteering” is identified the vehicle occupant protection elements are activated. The evaluation variable for monitoring the state of “oversteering” is determined by using a manipulated variable of the vehicle movement dynamics control system.

A method for preventively actuating a vehicle occupant protection element in a vehicle, comprising:
- monitoring an evaluation variable relating to a state of oversteering in a vehicle movement dynamics control system, the evaluation variable for monitoring the state of oversteering being determined using a manipulated variable of the vehicle movement dynamics control system;
- and
- activating the vehicle occupant protection element upon identifying the state of oversteering.
A device for protecting a vehicle occupant, comprising:
- a vehicle movement dynamics control system of the vehicle;
- a control unit;
- and
- a vehicle occupant protection element preventively actuatable by the control unit;
- wherein
- an evaluation variable is determinable by the control unit, and is usable to identify an oversteering condition of the vehicle, the vehicle occupant protection element being triggered automatically when the control unit identifies the oversteering condition, and the evaluation variable being determinable from a manipulated variable determined by the vehicle movement dynamics control system.
A control system for an occupant protection device of a vehicle, comprising:
- a control unit operatively connected to a vehicle movement dynamics control system of the vehicle;
- and
- a vehicle occupant protection element preventively actuatable by the control unit;
- wherein
- the vehicle movement dynamics control system monitors an evaluation variable relating to a state of oversteering, the evaluation variable being determined using a manipulated variable thereof;
- and
- the control unit actuates the vehicle occupant protection element upon identifying the state of oversteering.
