Process for assessing a rotational movement of a motor vehicle
First Claim
1. A process for assessing a rotational movement, in particular a rolling or rollover movement, of a motor vehicle, in which the angular velocity of the vehicle is measured several times about at least one vehicle axis, in particular about the longitudinal axis, the horizontal transverse axis and/or the vertical transverse axis of the vehicle, the angular acceleration of the vehicle about the at least one vehicle axis is ascertained from two measured angular velocities, and the ascertained angular acceleration is taken into account when assessing the rotational movement.

Abstract
The invention relates to a process for assessing a rotational movement, in particular a rolling or rollover movement, of a motor vehicle, in which the angular velocity of the vehicle is measured several times about at least one vehicle axis, in particular about the longitudinal axis, the horizontal transverse axis and/or the vertical transverse axis of the vehicle, the angular acceleration of the vehicle about the at least one vehicle axis is ascertained from two measured angular velocities, and the ascertained angular acceleration is taken into account when assessing the rotational movement. The invention also relates to a device for assessing a rotational movement, in particular a rolling or rollover movement, of a motor vehicle, and to a process for activating a vehicle safety system.

13. A device for assessing a rotational movement, in particular a rolling or rollover movement, of a motor vehicle, having at least one sensor for measuring the angular velocity of the vehicle about a vehicle axis, in particular about the longitudinal axis, the horizontal transverse axis or the vertical transverse axis of the vehicle, a computing unit connected to the sensor to ascertain the angular acceleration of the vehicle about the vehicle axis from two measured angular velocities, a comparator unit connected to the computing unit to compare the ascertained angular acceleration with a preset threshold value, and an evaluating unit connected to the comparator unit to evaluate a deviation of the ascertained angular acceleration from the threshold value.
