The invention relates to a method for limiting the travel speed (v) of a vehicle when traveling through a curve (K), in which a distribution of curvature (kappa) of a road section in front of the vehicle is determined by means of a digital map, in which a distribution of permissible curve speed (v) is determined as a function of the distribution of curvature (kappa) and a physical load limit of the vehicle, and in which the vehicle is controlled, the curvature (kappa) is determined in such a way that the determined permissible curve speed (v) is not exceeded when the vehicle travels through the curve (K), by evaluating the distribution of the curvature (kappa), a section having a curvature (kappa) greater than a predefined curvature limit value (kappa lim) is identified as a curve section, local curvature maxima are identified on the identified curve section, and for each local curvature maxima, the curvature (kappa) of the curve section (kappa) of the curve section (kappa) of the curve section (kappa) of the curve section (kappa) is determined. A permissible curve velocity (v) is determined from the curvature (kappa) and the permissible lateral acceleration (aqueerzul).
本发明涉及一种用于限制车辆在行驶通过弯道(K)时的行进速度(v)的方法，其中借助于数字地图来确定车辆前方路段的曲率(κ)的分布，其中根据该曲率(κ)的分布和车辆的物理负载限来确定容许弯道速度(v)的分布，并且控制车辆，使得在行驶通过弯道(K)时不超过所确定的容许弯道速度(v)，其中通过评估曲率(κ)的分布，将曲率(κ)大于预先规定的曲率限值(κlim)的路段识别为弯道路段，其中，在识别出的弯道路段上识别出局部曲率最大值，其中，针对每个局部曲率最大值，根据曲率(κ)和容许横向加速度(aquerzul)来确定容许弯道速度(v)。
