Abstract

In the driver assistance system, a function module is provided for a speed limiting function by which certain conditions for exceeding a predefined maximum speed and for decelerating again down to the maximum speed are implemented. The function module generates signals for carrying out one or more measures to generate or increase the braking torque. The signal for carrying out the measures can be only a binary signal, or can correspond to a required braking torque progression in the form of a regulating step so as to reach the maximum speed within a predefined time period. In the second case, the predefined time period is preferably shorter than a defined time window during which a warning intervention of the speed limiting function is suppressed during an exception where the maximum speed is allowed to be exceeded.
