Method for determining an evasion trajectory for a motor vehicle, and safety device or safety system

摘要

A method for determination of an optimized evasion trajectory by a safety device or a safety system, in particular a lane change assistance system and/or evasion assistance system, of a motor vehicle, the optimized evasion trajectory being outputted to a vehicle driver, and/or a trajectory of the motor vehicle being optionally partially adapted to the optimized evasion trajectory, by way of the method, the optimized evasion trajectory being determined by optimization of a transverse-dynamic quality factor (J), for which a transverse acceleration (a) and/or a transverse jerk ({dot over (a)}) of the motor vehicle is/are utilized. Also described is a safety device or a safety system, in particular to a lane change assistance system and/or an evasion assistance system for a motor vehicle, a method being executable and/or being executed by the safety device or the safety system.

1. A method of a motor vehicle system, the method comprising:
determining, by processing circuitry, an optimized evasion trajectory by optimization of a transverse-dynamic quality factor, wherein the transverse-dynamic quality factor is: based on at least one of a transverse acceleration and a transverse jerk of the motor vehicle; and exponentially weighted by a path-dependent weighting parameter that shifts a beginning of the optimized evasion trajectory or an actual evasive maneuver either forward or backward in time; and performing, by the processing circuitry, at least one of the following: outputting the optimized evasion trajectory to a vehicle driver; and partially adapting a trajectory of the motor vehicle to the optimized evasion trajectory.
