Abstract

In a method for detecting the reverse travel of a motor vehicle, the yaw speed and a model yaw-speed are obtained and, with the aid of these variables as well as constants, a factor .THETA.t is determined, which is compared to preselected comparison values. From these comparisons, it is determined whether forward travel or reverse travel exists.
