A control system having an ACC control, which for use in a host motor vehicle (ego) is configured and intended for recognizing a preceding motor vehicle (alter) and preferably preceding objects, based on surroundings data obtained from at least one front camera sensor associated with the host motor vehicle (ego). The front camera sensor (FKS) is configured for providing to an electronic control unit of the control system the surroundings data that represent an area in front of the host motor vehicle (ego). The control system is at least configured and intended for detecting another motor vehicle (alter) in traffic that is in front of the host motor vehicle (ego), by means of the at least one front camera sensor (FKS), determining a distance between the host motor vehicle (ego) and the preceding motor vehicle (alter), based on data from the front camera sensor (FKS),



determining a relevant difference in length (Diffrel), based on the last determined distance (At-1) and the instantaneously determined distance (At), determining a distance (AACC) to be used by the ACC control, based on the relevant difference in length (Diffrel) and the instantaneously determined distance (At), determining a measure of the criticality of the determined distance between the host motor vehicle (ego) and the preceding motor vehicle (alter), and outputting the distance (AACC) to be used to the ACC control of the host vehicle (ego) when the measure of the criticality deviates significantly from a limit value.
