ABSTRACT:
A method for obtaining an acceleration or deceleration signal from a signal proportional to the speed, consisting of storing the most recently ascertained n changes in a memory, wherein upon ascertainment of a new change to be stored in memory, the change which has been stored the longest is erased, and a deceleration or acceleration signal is formed by addition from the stored n changes, each time at intervals of .DELTA.T. Furthermore, in the method according to the invention, the presence of a deceleration or acceleration exceeding the threshold is recognized earlier.
