1. A control system which for use in a host motor vehicle (10) is configured and intended for recognizing motor vehicles traveling ahead, to the side, and/or behind and preferably stationary objects situated ahead, based on surroundings data obtained from at least one surroundings sensor associated with the host motor vehicle (10), wherein the at least one surroundings sensor is configured for providing an electronic controller of the control system with surroundings data that represent an area in front of, next to, or behind the host motor vehicle, the control system comprising:

  • detecting another motor vehicle (20) using the road, relative to the host motor vehicle (10), by means of the at least one surroundings sensor,determining movements of the other motor vehicle (20) relative to (i) a lane in which the other motor vehicle (20) or the host motor vehicle (10) is present, or (ii) the host motor vehicle,determining, starting from an instantaneous location of the host motor vehicle (10), a set having a predefined number of trajectories, differing with regard to their length and/or their course, for possible paths of the host motor vehicle (10), wherein the course of neighboring trajectories differs by a predefined difference between possible different steering angles of the host motor vehicle (10),correlating the course of the determined trajectories for possible paths of the host motor vehicle (10) with the provided surroundings data, and classifying the determined trajectories as (i) trajectories involving a collision, (ii) collision-free trajectories, and/or (iii) optimal trajectories,determining an instantaneously traveled trajectory of the host motor vehicle (10) and comparing it to the classified trajectories, andbased on this situation recognition for the host motor vehicle (10), making an intervention decision, and generating at least one signal that assists a driver of the host motor vehicle (10) in controlling the host motor vehicle (10) in order to guide the host motor vehicle (10) at least along a collision-free trajectory, or generating at least one associated control command that causes the host motor vehicle (10) to follow at least one of the collision-free trajectories.
