Abstract
A method for detecting impact and activating occupant protection devices, in which at least one acceleration signal from at least one acceleration sensor is compared with a triggering threshold. In this case, at least one environmental sensor for detecting an imminent impact and for determining at least one parameter of this imminent impact, in particular an expected time of impact and severity of impact, is provided. The triggering behavior is adapted on the basis of the parameters of the environmental sensor.
Claims5
A method of controlling an occupant protection device of a vehicle, the method comprising:
- receiving an acceleration signal from at least one acceleration sensor configured to sense an acceleration of the vehicle;
- determining an imminent impact protection between the vehicle and an object based on a parameter of the impact detected by an environmental sensor;
- and
- triggering action of the occupant protection device based on the parameter, wherein as of a starting time (t0), a triggering threshold (dth1=dth0+fth (G,t)) is increased fth (G,t), starting from a starting value (dth0), when the acceleration signal or a signal derived therefrom satisfies a minimum condition, wherein the starting time (t0) is set to an expected time of impact (TTC) when at least one parameter of the environmental sensor satisfies a specified condition.
