Generating method and apparatus of driving status signals in automobiles

(57) Abstract: The present invention relates to generating method or apparatus running state signal representing the running state of the automobile. The present invention, wheel acceleration value representative of the acceleration of the vehicle wheels is formed. Further, the acceleration values ​​representing a longitudinal acceleration of the vehicle is measured by the sensor. The essence of the present invention, a wheel acceleration value which is formed is low-pass filtered and measured acceleration values ​​are high-pass filtering, and running state signal is low-pass filtered wheel acceleration value and high-pass filtering It has been located to be generated as a function of binding to the acceleration values. The present invention, it is possible to determine the vehicle acceleration relative to the ground from the combination of the acceleration sensor signal and the wheel speed signal.
