The invention relates to a rearview mirror follow-up control method based on a front camera. The rearview mirror follow-up control method comprises the steps that the front camera recognizes a lane line; judging whether the vehicle is steered or not; the front camera sends vehicle steering angle information to the door module, and the door module drives the rearview mirror to rotate by an angle according to a calibration coefficient; judging whether the steering wheel is aligned; the door module drives the rearview mirror to rotate back to the initial position; the front camera is used for identifying a lane line and determining the advancing direction of the vehicle and the steering angle of the vehicle; judging whether the steering wheel is returned or not by a steering wheel angle sensor; the door module is used for controlling the rearview mirror lens to rotate correspondingly according to the angle provided by the front camera or the steering wheel angle sensor and the calibrated parameters; the rearview mirror is used for braking rotation of the lens according to the driving command of the door module. The rotating angle of the rearview mirror is accurately matched with the advancing direction of a real vehicle; return of the rearview mirror lens is controlled by adopting a signal of a steering wheel turning angle, and the two are combined to provide a clear view for a user.
本发明涉及一种基于前摄像头的后视镜随动控制方法,包括:前摄像头识别车道线;判断车辆是否已经转向;前摄像头将车辆转向角度信息发给门模块,门模块驱动后视镜按照标定系数转动角度;判断方向盘是否回正;门模块驱动后视镜转回初始位置;前摄像头用于识别车道线,确定车辆的前进方向及车辆转向的角度;判断方向盘是否回正由方向盘角度传感器反馈;门模块用于根据前摄像头或方向盘角度传感器提供的角度,按照标定的参数,控制后视镜镜片进行相应的转动;后视镜用于根据门模块的驱动命令制动镜片的转动。本发明实现后视镜的转动角度与实车前进方向的精确匹配;后视镜镜片的回位采用方向盘转角的信号进行控制,二者结合为用户提供一个清晰的视野。
