The invention provides a lane departure direction automatic correction system and method for a vehicle. The system comprises a lane departure controller, an electronic steering controller, a steeringmotor, a steering calibration switch and a camera device arranged in the middle of the front of the vehicle. The camera device collects road images; the lane departure controller is used for obtaininginformation that the vehicle deviates from the lane through image analysis and judgment and outputting vehicle adjustment parameter data in combination with the current vehicle speed of the vehicle,so that the vehicle is parallel to the lane line and is located in the middle of the lane after being adjusted according to the vehicle adjustment parameter data; and the electronic steering controller controls the steering motor to work according to the vehicle adjustment parameter data, and the steering motor rotates steering wheels of the vehicle to achieve vehicle steering adjustment. A virtual vehicle and a virtual center line are drawn in a collected front road image, the direction and angle of the vehicle are judged and adjusted according to the distances between the two sides of the lane and the virtual vehicle, and the vehicle can be kept in the middle of the lane in the running process through real-time adjustment.

    本公开提出了一种用于车辆的车道偏离方向自动修正系统及方法,系统包括车道偏离控制器、电子转向控制器、转向电机与转向标定开关,以及设置在车辆前方中间位置的摄像装置;摄像装置采集道路图像;车道偏离控制器:通过图像分析判断获得车辆偏移车道的信息,结合车辆的当前的车速输出车辆调整参数数据,使得车辆按照车辆调整参数数据调整后车辆与车道线平行并处于车道的中间位置;电子转向控制器:按照车辆调整参数数据控制转向电机工作,转向电机转动车辆的转向轮实现车辆转向调整。通过在采集的前方道路图像中绘制虚拟车辆以及虚拟中线,根据车道两侧与虚拟车辆的距离判断调整车辆的方向及角度,实时调整实现车辆行驶过程能保持在车道的中间位置。
