Abstract
The invention relates to a method for detecting a rollover situation in such a way that a restraint, such as belt tighteners or head airbags, can be released at the right time during rollover. The signals that pertain to several sensors and detect transitional and rotational movements are detected, connected to one another and evaluated.
Claims7
A method for detecting a rollover, comprising:
- detecting a translatory movement and a rotary movement of the vehicle;
- determining a rollover threshold, wherein the rollover threshold is dependent on a) acceleration of the vehicle in the vertical direction, b) acceleration of the vehicle perpendicular to its longitudinal axis, and c) the rotary movement of the vehicle and
- triggering a restraint device if the rotary movement exceeds the rollover threshold.
Dependencies are inferred from the claim text.
