When the temperature rises to a certain degree or in rainy and snowy days, the large screen and the mobile phone APP remind that the hood can be opened, and the mobile phone APP can be controlled through a key switch in the car. In operation, 4 canopies (two inner canopies 2A and two outer canopies 2B) on the left and right sides of the vehicle can be opened by one key, a sun-shading and snow-proofing mode (opening the inner two inner canopies 2A) can be opened independently, a camping mode (opening the side two outer canopies 2B) can be opened independently, and any specified canopies can be opened independently.

In one possible embodiment, in the camping mode, the method further comprises:

if the sun shade exists under any one of the two sides of the vehicle according to the light intensity signals of the two sides of the vehicle distributed along the Y direction, and the measured real-time temperature is in the medium temperature range, the inner awning 2A of the telescopic awning 2 is controlled to retract; specifically, when judging whether one of the two sides of the vehicle has sun shadows, comparing the light intensity signals of the two sides of the vehicle, and if the difference value of the light intensity signals of the two sides of the vehicle is larger than a set value, judging that one of the two sides of the vehicle has sun shadows;
