The embodiment of the invention discloses a vehicle curve transverse control method and system, electronic equipment and a storage medium. The method comprises the steps that whether a vehicle is driven into a curve or not is judged according to the real-time driving road condition of the vehicle and steering information based on radar recognition; after it is judged that the vehicle drives into the curve, detecting the road condition of the curve based on a radar; calculating a steering wheel turning angle timetable of the vehicle according to the curve road condition and the real-time driving road condition of the vehicle; a local nonlinear fitting method is adopted to match corresponding steering wheel turning angles when the vehicle runs at a plurality of moments in the future; and according to the corresponding steering wheel turning angles during the driving at the plurality of moments in the future, performing curve control during the driving at the plurality of moments. The steering information of a certain position of the vehicle in the future is calculated in advance and does not belong to correction feedback after errors occur, meanwhile, the steering angle of the steering wheel corresponds to the future moment in the future, and the accuracy of future steering of the vehicle is guaranteed.
本申请实施例公开了一种车辆弯道横向控制方法、系统、电子设备及存储介质,所述方法包括:根据车辆实时行驶路况和基于雷达识别的转向信息判断车辆是否驶入弯道;在判定车辆驶入弯道后,基于雷达探测出弯道路况;根据所述弯道路况和车辆实时行驶路况计算车辆的方向盘转角时刻表;采用局部非线性拟合方法匹配出车辆未来若干时刻行驶时对应的方向盘转角;根据所述未来若干时刻行驶时对应的方向盘转角在所述若干时刻行驶时进行弯道控制。通过预先计算车辆未来某位置的转向信息,不属于出现误差后的修正反馈,同时做到了未来方向盘转角与未来时刻的对应,保证了车辆未来转向的准确。
