A driver assistance system is provided in a motor vehicle, which driver assistance system executes at least active transverse guidance interventions. The driver assistance system can be activated while decoupled from the activation of a longitudinal control system but can also be active both, with and without longitudinal control, and includes both a traffic jam assistance sub-function and a track guiding assistant sub-function. The two sub-functions can be jointly activated and deactivated by a single on-/off-button. The driver assistance system is characterized by a special combination of the sub-functions track guiding assistance and traffic jam assistance. They each take turns depending on the presence of conditions, which are defined differently for each sub-function.

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.
