Method and device for actuating a vehicle occupant protection means
First Claim
1. A method for actuating a vehicle occupant protection device in a vehicle that has a sensor system which acquires driving state data, wherein the vehicle occupant protection device is reversible, and can be triggered before a collision time and thus moved into an operative position said method comprising:
- if at least one first condition that is indicative of a critical driving state is detected, activating a control signal for triggering the vehicle occupant protection device; and
deactivating the control signal, and initiating a resetting of the vehicle occupant protection device to an initial state, if bothi) the detected at least one first condition indicative of a crucial driving state ends; and
ii) at least one further condition that is indicative of a return to controllable driving behavior is detected, wherein,in order to sense a return to controllable driving behavior, a vehicle movement dynamics control system is monitored as a function of one of time and state, to detect a non-activated status; and
said monitoring comprises checking whether the vehicle movement dynamics control system remains non-activated for a predefined time period.

Abstract
A method and apparatus for preventatively actuating a vehicle occupant protection system in a vehicle having a sensor system which acquires driving state data, and a reversible vehicle occupant protection means which can be triggered before the collision time and thus moved into an operative position. A control signal for triggering the vehicle occupant protection means is activated if at least one critical driving state is present, and is deactivated if the respective critical driving state ends and as a function of at least one further condition which represents at least one sensed controllable driving behavior. As a result, the vehicle occupant protection system is reset to its initial state.

11. A method for actuating a vehicle occupant protection device in a vehicle that has a sensor system which acquires driving state data, wherein the vehicle occupant protection device is reversible, and can be triggered before a collision time and thus moved into an operative position said method comprising:
-
if at least one critical driving state is detected, activating a control signal for triggering the vehicle occupant protection device; and if the detected critical driving state ends, deactivating the control signal, and initiating a resetting of the vehicle occupant protection device to an initial state;
whereinthe control signal is deactivated as a function of at least one further condition which represents at least one sensed controllable driving behavior; and in order to sense the controllable driving behavior, the absolute value of the yaw rate is monitored to detect undershooting of a first predefined threshold value. - View Dependent Claims (12, 13)
