A GLC owner said that his car has 360 panoramic images, but when the speed is lower than 30km / h, the rear camera often turns on and off automatically, and the central control does not display a fault, but the sound of the flap can be heard. How can this happen? Is something wrong?

先给下观点：如果只是速度30km/h一下才会出现，那大概率不是问题。

Let's give a point of view first: if it only occurs at a speed of 30km / h, the high probability is not a problem.

低速后摄像头自动打开关闭的情况是基于系统特性，需要校准后摄像头所致。

The automatic opening and closing of the rear camera at low speed is caused by the need to calibrate the rear camera based on the system characteristics.

因车型不同，车速的规定可能不同，有的是低于20km/h，有的是低于30km/h，另外还有一个条件就是方向盘的转向角要小于10°。

Due to different models, the speed regulations may be different, some are lower than 20km / h, some are lower than 30km / h, and another condition is that the steering angle of the steering wheel should be less than 10 °.

满足上面两个条件，如果有需要，后摄像头会在车辆前进的时候，自动打开/关闭进行校准。

The above two conditions are met. If necessary, the rear camera will automatically turn on / off for calibration when the vehicle is moving forward.

校准的时候，你的车辆后面要没车，因为摄像头必 须拍到柏油路，才会完成校准，整个过程大概持续1分钟左右，也就是你少要低速向前行驶1分钟以上，后摄像头才可能完成校准，关闭后摄像头盖。

During calibration, there should be no car behind your vehicle, because the camera must shoot the asphalt road before the calibration can be completed. The whole process lasts about 1 minute, that is, you need to drive forward at low speed for more than 1 minute before the rear camera can complete the calibration and close the rear camera cover.

整个校准过程中，如果有某些条件不符合，校准会自动退出，然后符合条件后又开始，如果往复。所以，如果你遇见这个问题，就是找个车少的路段，低速行驶几分钟，让校准彻 底完成。

During the whole calibration process, if some conditions are not met, the calibration will exit automatically, and then start again after meeting the conditions. So, if you encounter this problem, just find a road with few cars and drive at low speed for a few minutes to complete the calibration.
