Abstract
A method and an apparatus for generating a driving status signal that represents the driving status of a motor vehicle. A wheel acceleration variable representing the acceleration of the vehicle wheels is formed. In addition, an acceleration variable representing the longitudinal acceleration of the vehicle is sensed by way of sensors. The wheel acceleration variable that is formed is low-pass filtered, and the acceleration variable that is sensed is high-pass filtered. The driving status signal is generated as a function of an association between the low-pass-filtered wheel acceleration variable and the high-pass-filtered acceleration variable. As a result, it possible to determine the vehicle's ground acceleration from a combination of the signals of an acceleration sensor and the wheel rotation speed signals.
