The invention relates to a method for automatically assisting a motor vehicle (6) in driving at an exit (2) of a main road (1), in which a current position (16) of the motor vehicle (6) is determined, in which an imminent driving at the exit (2) is identified, and in which geometry data (22) of the exit (2) is acquired from a first database (20) on the basis of the current position (16), according to the invention, current information (26) relating to a traffic lane characteristic (30) of the exit (2) and/or to a traffic situation (28) in the exit (2) is detected and/or determined from a second database (24) on the basis of the current position (16), a critical speed (vk) at which the motor vehicle (6) travels at the exit (2) is determined on the basis of geometry data (22) of the exit (2) and on the basis of information (26) relating to a traffic lane characteristic (30) of the exit (2) or to a traffic condition (28) in the exit (2), and/or a parameter (36) relating to a turn-around driving performance (q) of the motor vehicle (6) is determined, and wherein the threshold speed (vk) of the motor vehicle (6) travels at the exit (2), and outputting at least one warning signal and/or actuating the braking process as a function of the determined critical speed (vk) and/or the determined parameter (36) relating to the turning driving performance (a).
本发明涉及一种针对在主路(1)的出口(2)行驶自动辅助机动车(6)的方法,其中,确定机动车(6)的当前位置(16),其中,识别出即将在出口(2)行驶,其中,根据当前位置(16)从第一数据库(20)中获取出口(2)的几何形状数据(22),其中,检测和/或根据当前位置(16)从第二数据库(24)中获取与出口(2)的行车道特性(30)有关的和/或与出口(2)中的交通状况(28)有关的当前信息(26),其中,根据出口(2)的几何形状数据(22)以及根据与出口(2)的行车道特性(30)或与出口(2)中的交通状况(28)有关的信息(26)来确定机动车(6)在出口(2)行驶的临界速度(vk),和/或确定关于机动车(6)的拐弯行驶性能(aq)的参数(36),以及其中,根据所确定的临界速度(vk)和/或所确定的关于拐弯行驶性能(aq)的参数(36)输出至少一个警告信号和/或操控制动过程。
