The invention discloses an anti-sliding method and system after ramp parking, and belongs to the technical field of automobiles, and the method comprises the steps: obtaining a ramp road image, and detecting a road edge in the ramp road image through a road edge detection model; obtaining coordinates of the road edge on the imaging plane, and obtaining road plane coordinates of the road edge through the coordinates on the imaging plane; obtaining distance information from the camera to the road edge through Euclidean distance calculation according to the road plane coordinates of the road edge, then obtaining the distance from the wheel to the road edge by combining the transverse distance from the camera to the wheel, and performing wheel steering and road edge contact according to the distance from the wheel to the road edge. The purpose of preventing the vehicle from sliding after the vehicle is parked on the ramp is achieved through the camera, the ESC, the EPS and the like, cost is not increased, other devices do not need to be additionally installed, and practicability is high.
本发明公开了一种坡道停车后防溜车方法及系统,属于汽车技术领域,其中,方法的实现包括:获取坡道道路图像,通过路沿检测模型检测出坡道道路图像中的路沿;获取路沿在成像平面上的坐标,由成像平面上的坐标得到路沿的道路平面坐标;根据路沿的道路平面坐标通过欧式距离计算得到摄像头到路沿的距离信息,再结合摄像头到车轮的横向距离,得到车轮到路沿的距离,根据车轮到路沿的距离进行车轮转向与路沿接触。本发明通过摄像头、ESC、EPS等实现车辆坡道停车后防溜车的目的,不增加成本,不需要额外安装其它装置,实用性较强。
