Abstract
A method for detecting a rollover on the basis of a signal of an acceleration sensor in the direction of the vertical axis of the vehicle is described, wherein the time period in which acceleration lies within a specified range is assessed. For this purpose, a counter and a clock generator are provided, wherein the counter is incremented each clock pulse if acceleration lies within a specified range, and the counter is decremented maximally to the value of zero if acceleration lies outside of a specified range. An emergency call may be triggered if a specified counter reading is reached. Additionally, a maximum speed may be specified in the travel direction above which the counter or the triggering is not active.
