Further, the following implementation methods are given:

The ambient light control instrument panel system 6 is used to set the color control parameters of the nano touch film 2 to realize the adjustment of light transmittance;

Regardless of whether the vehicle is stationary or running, if it is in manual control mode, the driver’s hand position and gesture tracking and sensing module 1 will match the driver’s gestures with the specific gestures preset in the MCU micro-control unit 3 if it is in manual control mode , the matching is successful, and the MCU micro-control unit 3 sends a control signal to make the nano-touch film 2 pasted and completely covered on each window of the vehicle change the light transmittance to a set value.

Otherwise, it is processed separately according to the driving state. If the vehicle is stationary: the MCU micro-control unit 3 obtains the signals fed back by the temperature sensing module 4-1 inside the vehicle and the temperature sensing module 4-2 outside the vehicle and controls the instrument panel system 6 through the ambient light.

Eye irritation, avoid traffic accidents.

When the vehicle is running/stationary, or at any time, when the ambient light control instrument panel system 6 is set and enters the "gesture recording mode", the MCU micro-control unit 3 activates the tracking and sensing module of the driver's hand position and gesture in the main driving position 1. Enter the control gestures according to the driver's habits, and record the gestures in the MCU micro-control unit 3; during the driving process of the vehicle, the driver's hand position and gesture tracking and sensing module 1 continues to work, and the driver passes Making specific gestures entered in advance can realize the control of the intelligent control system of the external ambient light of the vehicle, and achieve the purpose of performing gesture operations on the system without shifting the line of sight to the ambient light control dashboard system 6. Conducive to driving safety. The co-driver and rear passengers can directly touch the nano-touch film 2 that is pasted and completely covered on the window glass on both sides of the co-driver and rear passengers to call up the control menu interface on the nano-touch film 2 to control the outside world of the car. The ambient light intelligent control system performs touch operation similar to that of a smart phone.

The specific implementation of the present invention has been described in detail above in conjunction with the drawings, but the present invention is not limited to the above-mentioned implementation, within the knowledge of those of ordinary skill in the art, can also make various kind of change.
