Arrangement for plausibilizing a rollover decision
First Claim
1. An arrangement for plausibility checking of a rollover decision in a motor vehicle, with one or more yaw rate sensors and/or acceleration sensors (DS) detecting movements of the vehicle and a processor (PZ) deriving a decision (e1) from the sensor signals (ω
- ) as to whether the vehicle movements will result in a rollover, and with means (SE) being present which produce, from measured accelerations (az, ay) in the direction of the vertical axis and the transverse axis of the motor vehicle, a criterion for plausibility checking of a rollover decision which has been made, wherein the means (SE) signal plausibility of a rollover decision (e1) if the acceleration (az) measured in the direction of the vertical axis is either greater than a preset upper threshold or less than a preset lower threshold, or if the acceleration (az) measured in the direction of the vertical axis is between the two thresholds, but the acceleration (ay) measured in the direction of the transverse axis simultaneously exceeds a threshold (ays) which depends on the acceleration (az) measured in the direction of the vertical axis.

Abstract
In order to perform a simple plausibility check of a rollover decision which is as reliable as possible, an arrangement is provided which signal plausibility of the rollover decision if an acceleration measured in the direction of the vertical axis of the vehicle is either above a preset upper threshold or below a preset lower threshold, or if the acceleration measured in the direction of the vertical axis is between the two thresholds, but an acceleration measured in the direction of the transverse axis of the motor vehicle simultaneously exceeds a threshold which depends on the acceleration measured in the direction of the vertical axis.
