Abstract

A control system that is suitable for use in a host motor vehicle (10) is configured and intended for detecting (S100) another motor vehicle (20), using the road, located in front of the host motor vehicle (10) by means of the at least one surroundings sensor, determining (S106) a lateral movement of the other motor vehicle (20) relative to a lane (12, 16) in which the other motor vehicle (20) or the host motor vehicle (10) is present, and computing (S108) a movement-based likelihood of a lane change by the other motor vehicle (20), based on the determined lateral movement of the other motor vehicle (20). In addition, the control system is configured and intended for determining (S110, S112, S114) an instantaneous traffic situation in accordance with the surroundings data obtained by means of the surroundings sensor, computing (S116) a traffic situation-based likelihood of a lane change by the other motor vehicle (20), based on the determined instantaneous traffic situation, and computing (S118) an overall likelihood of a lane change by the other motor vehicle (20), based on the movement-based likelihood and the traffic situation-based likelihood.
