Patent ID: 8768572

Claim:
An apparatus for detecting a rollover event, comprising: at least one first acceleration sensor in a vertical direction of a vehicle; at least one second acceleration sensor in at least one horizontal direction of the vehicle; and a processor for detecting an inertial event as a function of a first signal of the at least one second acceleration sensor, and after detection of the inertial event, evaluating a second signal from the at least one first acceleration sensor for detecting the rollover event, the processor triggering a restraint device as a function of the first signal and the second signal; wherein the processor detects the inertial event in the form of the deployment of the restraint device in the event of one of (i) a head-on crash and (ii) a lateral crash or as a function of an acceleration signal in one of (i) a longitudinal direction of the vehicle and (ii) a transverse direction of the vehicle.
