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?

先給下觀點：如果只是速度30km/h一下才會出現(xiàn)，那大概率不是問題。

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.

低速后攝像頭自動打開關(guān)閉的情況是基于系統(tǒng)特性，需要校準(zhǔn)后攝像頭所致。

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.

因車型不同，車速的規(guī)定可能不同，有的是低于20km/h，有的是低于30km/h，另外還有一個條件就是方向盤的轉(zhuǎn)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 °.

滿足上面兩個條件，如果有需要，后攝像頭會在車輛前進的時候，自動打開/關(guān)閉進行校準(zhǔn)。

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

校準(zhǔn)的時候，你的車輛后面要沒車，因為攝像頭必 須拍到柏油路，才會完成校準(zhǔn)，整個過程大概持續(xù)1分鐘左右，也就是你少要低速向前行駛1分鐘以上，后攝像頭才可能完成校準(zhǔn)，關(guān)閉后攝像頭蓋。

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.

整個校準(zhǔn)過程中，如果有某些條件不符合，校準(zhǔn)會自動退出，然后符合條件后又開始，如果往復(fù)。所以，如果你遇見這個問題，就是找個車少的路段，低速行駛幾分鐘，讓校準(zhǔn)徹 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.
