The invention is suitable for the technical field of intelligent driving assistance, and particularly relates to a method and system for detecting the width of a lane where a vehicle is located, and the system comprises a sensing unit, a calculation unit, a judgment unit, a compensation unit and a delay unit. The parameters comprise the transverse distance between the center of a rear axle of the automobile and a lane line, the slope of the lane line and the curvature of the lane line, when the lane line on one side is valid, compensation calculation needs to be carried out, and the delay unit is used for carrying out delay processing on the lane width when lane line validity setting signals are invalid, and it is guaranteed that the transverse and longitudinal control functions of the automobile exit smoothly. The distance between the current vehicle and the lane lines on the two sides is determined by recognizing the lane lines, when the lane line on one side disappears or the lane lines on the two sides disappear, the lane width is determined based on the detected lane width data, the continuity of the transverse and longitudinal control function of the vehicle is guaranteed, and the driving comfort is improved.
本发明适用于智能驾驶辅助技术领域,尤其涉及一种车辆所处车道宽度检测的方法及系统,所述系统包括:感知单元、计算单元、判断单元、补偿单元和延时单元所述感知单元用于识别当前车道的参数,所述参数包括自车后轴中心距离车道线的横向距离、车道线斜率和车道线曲率,当单侧车道线有效时需进行补偿计算,所述延时单元用于在车道线有效性置位信号均无效时,对车道宽度进行延时处理,保证汽车横纵向控制功能平滑退出。本发明通过对车道线进行识别,确定当前车辆与两侧车道线之间的距离,在一侧车道线消失或者两侧车道线都消失时,基于检测到的车道宽度数据来确定车道宽度,保证了汽车横纵向控制功能的连续性,提升了驾驶舒适性。
