The invention discloses an automobile electric sun shield with an automatic adjusting function and a control method, and relates to the technical field of automobile electric appliances. The system comprises a front camera, an in-vehicle camera, a control unit and a sun shield controlled by a motor. The control unit calculates the included angle between the incident light of the sun and the X-axis direction of the vehicle and the position coordinates of the eyes of a driver relative to the camera in the vehicle according to images captured by the camera in front of the vehicle and the camera in the vehicle, and stores the coordinates of the camera in the vehicle relative to the rotating shaft of the sun shield, the size of the sun shield and other parameters. Calculating whether the sun shield is overturned or not and the overturning angle, and controlling a sun shield motor to act; when sunlight irradiates into the eyes of a driver from the front windshield, the sun shield can be automatically turned over to the optimal angle, dazzling of the driver caused by the sunlight is prevented, and the view of the driver is not excessively shielded; the situation that a driver distracts attention to manually adjust the sun shield in the driving process is avoided, and comfort is improved.

    本发明公开了一种带自动调节功能的汽车电动遮阳板及控制方法,涉及汽车电器技术领域。本发明包括车前摄像头、车内摄像头、控制单元及由电机控制的遮阳板组成。本发明控制单元根据车前摄像头和车内摄像头捕捉到的图像计算太阳入射光线与车辆X轴方向的夹角、驾驶员眼部相对车内摄像头的位置坐标,存储车内摄像头相对遮阳板转轴坐标,遮阳板尺寸等参数,计算遮阳板是否翻转及翻转的角度并控制遮阳板电机动作;当太阳光线从前挡风玻璃照射进驾驶员眼部时,遮阳板能够自动翻转到最优的角度,防止阳光对驾驶员造成炫目且不过度遮挡驾驶员视野;避免了驾驶员在行车过程中分散注意力来手动调整遮阳板,提高了舒适性。
