Abstract

A control device in a motor vehicle for detecting an impact and for detecting a rotational movement includes a transversal acceleration pick-up in each half of the vehicle, as defined by the longitudinal axis of the vehicle, and a longitudinal acceleration pick-up. An evaluation device evaluates longitudinal acceleration and transversal acceleration variables and derives a rotational movement variable from the transversal acceleration variables.
