Problems solved by technology

However, the disadvantage is that with such a soft setting of the regulator parameters, the accuracy in terms of the target trajectory to be regulated becomes significantly lower
In other words, in this case, there is no guarantee that the vehicle is indeed also traveling on the planned target trajectory, and more or less strong deviations from this target trajectory may occur, which in turn may lead to very safety-related situations and possible collision
Of course, since safety-critical situations should be avoided in all cases, it is often preferable to hard-code the parameters, but at the expense of comfort

Abstract

The invention relates to a driver assistance system (11) for an at least partially automatically driving motor vehicle (10), wherein the driver assistance system (11) comprises at least one environment detection means (13) which is designed to detect at least one area of an environment (U) of the motor vehicle (10), an evaluation device (14) which is designed to determine a target trajectory (T) to be travelled by the motor vehicle (10) according to the detected at least one area of the environment (U), and a control device (18) which is designed to adjust the target trajectory (T) determinedby the evaluation device (14). According to the invention, the evaluation device (14) is designed to determine at least one free area value (W) according to the detected at least one area of the environment (U), and to transfer same to the control device (18), wherein the control device (18) has at least one adjustable control parameter (R1, R2, Rn), and the control device (18) is designed to adjust the at least one control parameter (R1, R2, Rn) according to the transferred free area value (W), and to adjust the target trajectory (T) according to the adjusted at least one control parameter (R1, R2, Rn).

Description

technical field [0001] The invention relates to a driver assistance system for at least partially autonomous driving of a motor vehicle, wherein the driver assistance system has: at least one environment detection device designed to detect at least one area of ​​the environment of the motor vehicle; An analysis device designed to determine a target trajectory to be driven by the motor vehicle as a function of at least one region of the detected environment; and a vehicle dynamics regulation system with a regulator device designed to regulate The target trajectory determined by the analysis device. The invention also includes a motor vehicle with such a driver assistance system and a method for adjusting the vehicle dynamics of a motor vehicle. Background technique [0002] DE 10 2012 203 187 A1 describes a method and a device for detecting and adapting a motion trajectory of a motor vehicle. In particular, the method is used to determine an optimal avoidance trajectory if ...
