The invention relates to a method and a correspondingly designed system for assisting a driver of a vehicle in keeping on a lane, comprising the following steps: detecting a driving state measurement signal of the vehicle; determining a travel trajectory of the vehicle on the basis of the detected travel state measurement signal; detecting an environmental information signal of the vehicle; determining a lane trajectory of a lane on which the vehicle moves on the basis of the environmental information signal; -determining an intersection of the determined travel trajectory with the determined lane trajectory; -determining, on the basis of the determined intersection, whether a lane departure situation exists and possibly also a lane return situation exists; -on the basis of determining whether a lane departure situation is present and possibly also a lane return situation is present, sending a signal for causing the driver to be assisted in keeping on the lane.
本发明涉及用于辅助车辆的驾驶员保持在车道上的方法和相应设计的系统,包括以下步骤:‑检测车辆的行驶状态测量信号;‑基于检测到的所述行驶状态测量信号来确定所述车辆的行驶轨迹;‑检测所述车辆的环境信息信号;‑基于所述环境信息信号来确定所述车辆在其上移动的车道的车道轨迹;‑确定所确定的所述行驶轨迹与所确定的所述车道轨迹的交叉点;‑基于所述确定的所述交叉点来判定是否存在车道偏离情况以及可能还存在车道返回情况;‑基于判定是否存在车道偏离情况以及可能还存在车道返回情况,发送用于引起辅助所述驾驶员保持在所述车道上的信号。
