The invention discloses a self-adaptive steering driving assistance method based on a high-precision map, which comprises the following steps: when a positioning device detects that the distance between the driving vehicle and a front appointed road is less than or equal to a preset distance, a vehicle-mounted radar detects whether a front vehicle exists on the front appointed road; when the detection result is that the front vehicle exists, maintaining the measurement angle of the vehicle-mounted radar; when the detection result is that the front vehicle does not exist, continuously adjusting the measurement angle of the vehicle-mounted radar according to the specified road condition; maintaining the measurement angle of the vehicle-mounted radar at the moment until the detection result is changed to be that the front vehicle exists; if the vehicle-mounted radar is adjusted to the preset upper limit angle and the detection result is still that the front vehicle does not exist, the vehicle-mounted radar is adjusted back to the initial angle; when the vehicle drives out of the designated road, the vehicle-mounted radar is adjusted back to the initial angle. According to the planning decision, the radar is driven by a machine to calculate rotation in the horizontal and pitching directions according to the angle value corresponding to the road condition, the field angle is increased, the road condition of the front vehicle is accurately detected, and the exploration performance of the radar on the vehicle condition in front of the lane is enhanced.

    本发明公开了一种基于高精度地图的自适应转向驾驶辅助方法,包括步骤:当定位装置检测到本车行驶与前方指定道路的距离小于或等于预设距离时,车载雷达检测前方指定道路上是否存在前车;当检测结果为存在前车时,维持车载雷达测量角度;当检测结果为不存在前车时,根据指定道路路况持续调节车载雷达测量角度;直至检测结果变更为存在前车时,维持此时车载雷达测量角度;若调节至预设上限角度且检测结果仍为不存在前车时,车载雷达回调至初始角度;当本车驶出指定道路,车载雷达回调至初始角度。本发明规划决策适时用机械带动雷达在水平和俯仰方向的计算转动与路况相应的角度值增大视场角准确探测前车路况,加强了雷达对车道前方车况的探索性能。
