The invention provides a method and system for improving curve lane changing safety of an automatic driving vehicle, and the method comprises the steps: when the vehicle is recognized to be on a curve and is ready to change the lane, if the vehicle is on the curve which is bent leftwards to change the lane rightwards, an angle radar rotation angle calculation module calculates the rotation angle of the angle radar according to the curvature of a lane line in front of the vehicle; the angle theta that the angle radar should rotate is calculated and transmitted to a right front angle radar rotating module to drive the right front angle radar to rotate; when the vehicle is recognized to be in the curve and prepare to change the lane, if the vehicle changes the lane leftwards in the curve which is bent rightwards, the angle radar rotation angle calculation module calculates the angle theta that the angle radar should rotate according to the curvature of the lane line in front of the vehicle, and transmits the angle theta to the left front angle radar rotation module to drive the left front angle radar to rotate.
本发明提供了一种提高自动驾驶车辆弯道变道安全性的方法及系统,其中,所述方法包括:当识别到车辆在弯道并且准备变道时,若车辆在向左弯曲的弯道进行右变道,角雷达旋转角度计算模块根据车辆前方车道线的曲率,计算出角雷达应该旋转的角度θ,传输给右前角雷达旋转模块带动右前角雷达执行旋转动作;当识别到车辆在弯道并且准备变道时,若车辆在向右弯曲的弯道进行左变道,角雷达旋转角度计算模块根据车辆前方车道线的曲率,计算出角雷达应该旋转的角度θ,传输给左前角雷达旋转模块带动左前角雷达执行旋转动作。
