The invention provides a control system and control method for determining a trajectory and for generating associated signals or control commands. A control system for use in a host motor vehicle (10)is configured and intended for ascertaining an instantaneous driving situation of the host motor vehicle (10) and determining a trajectory (42) for the host motor vehicle (10) that the host motor vehicle (10) is to follow for carrying out a driving maneuver, in accordance with the ascertained instantaneous driving situation of the host motor vehicle (10), a desired driving situation of the host motor vehicle (10), the driving dynamics of the host motor vehicle (10), and the surroundings data (64). The control system is further configured and intended for generating at least one associated signal (61) that assists a driver of the host motor vehicle in controlling the host motor vehicle (10) in order to follow the trajectory (42), or generating at least one associated control command (61) that causes the host motor vehicle (10) to autonomously follow the trajectory (42), essentially simultaneously with determining the trajectory (42).
