Method and device for controlling an occupant protection device in a vehicle
First Claim
1. A method for triggering an occupant protection device in a vehicle, comprising:
- detecting a first measured variable while simultaneously generating a corresponding first signal for indicating a necessity for triggering the occupant protection device;
detecting an acceleration value in a z direction while simultaneously generating a corresponding second signal, wherein the z direction is a vertical direction;
calculating a trigger signal for triggering the occupant protection device as a function of the first signal and the second signal, wherein a level of the occupant protection device triggering signal is reduced as a function of at least one of a vertical axis acceleration signal and a vehicle model; and
triggering the occupant protection device as a function of the calculated trigger signal, wherein a deployment threshold for generating the trigger signal is elevated as a function of the acceleration in the z direction.
