Lane change assistance system

Lane changing assistance system (1) for motor vehicles for a lane change of a Egofahrzeuges (21) from its own lane (22) to a target traffic lane (23) - a surroundings-sensing unit (2), the other vehicles located for sensing in the area of ​​the Egofahrzeuges (21) (24, 25a to 25c) and their respective vehicle state is established, - a gap determining unit (5) for determining at least one Einscherlucke (26a, 26b) on the target lane (23) in response to the detected other vehicles and their respective vehicle state is established, - a lane change evaluation unit, which is set up - for each identified Einscherlucke (26a, 26b), starting from the position of the Egofahrzeuges (21), a plurality (26a, 26b) to determine bezuglicher of Zieltrajektorien of different target positions (A1 to A5, B1 to B5) within the respective Einscherlucke, - a longitudinal action space (31) of the Egofahrzeuges (21) in dependence on driving dynamics to determine the Egofahrzeuges (21), and - for each target trajectory Trajektorienbewertung a function of the determined action longitudinal space (31) taking into account the predicted vehicle conditions at the time of reaching the target positions (A1 to A5, B1 to B6) for calculating the respective Zieltrajektorien, and - an output unit (7), which is designed for the output of the Trajektorienbewertungen Zieltrajektorien to the vehicle operator and / or to a control device of the Egofahrzeuges, characterized in that the lane change judgment unit is configured to determine a total gap rating depending on the Trajektorienbewertungen the respective Zieltrajektorien the respective Einscherlucken for each determined Einscherlucke, and the output unit is configured to output the Trajektorienbewertungen in the form of the total gap review.
