The electric control module 3 is also electrically connected with other electric control modules on the vehicle, such as a vehicle body ECU, an air conditioner ECU, a transmission system ECU and the like, through a CAN bus 8, and the electric control module 3 is grounded through a grounding port GND.

Illustratively, the window glass 1 can be respectively transparent color and opaque color when being powered on and powered off, the position switch 21 is closed when the window glass 1 is completely closed, a passenger in the vehicle can control the on and off of the control switch 7, and when the passenger in the vehicle opens the control switch 7, the connection loop of the electric control module 3 and the window glass 1 can be powered off, and the window glass 1 can be changed into the opaque color, so that the privacy of the passenger in the vehicle can be protected. When the window glass 1 is not completely closed, the position switch 21 is opened, and the position switch 21 and the control switch 7 are connected in series, so that when the position switch 21 is opened, the on and off of the control switch 7 do not affect the power-off state of the high-voltage line 4, and because the window glass 1 is not completely closed, the window glass 1 becomes transparent or opaque and has no influence on people in the vehicle basically, so that the influence of the high-voltage line 4 on the safety of passengers in the vehicle when the window glass 1 is not completely closed is avoided by opening the position switch 21, and when the window glass 1 is completely closed, the position switch 21 is closed, and the people in the vehicle can control the window glass 1 to change the transparency by closing or opening the control switch 7, so that different requirements of the people in the vehicle on the transparency and the opacity of the glass are met.

Alternatively, the control switch 7 is provided inside the door.

For example, the control switch 7 may be disposed inside a door corresponding to the window glass 1, so as to facilitate an operation of the control switch 7 by a passenger in the vehicle, for example, when the window glass 1 is completely closed, the control switch 7 may be opened to make the window glass 1 opaque, and the control switch 7 may be closed to make the window glass 1 transparent; when the window pane 1 is not completely closed, the position switch 21 is open, the control switch 7 is not actuated, and the window pane 1 is opaque.

Optionally, the voltage input by the input terminal a1 of the electronic control module 3 is 12V dc voltage, and the control voltage output by the output terminal a2 of the electronic control module 3 is 110V ac voltage.

Specifically, the power module 6 may provide 12V dc voltage for the electric control module 3, and the electric control module 3 may output 110V control voltage to the window glass 1 after inputting the dc voltage of the power module 6, and since the voltage required for changing the transparency of the window glass 1 is higher, the electric control module 3 provides 110V ac control voltage for changing the color of the window glass 1 for the window glass 1, thereby controlling the window glass 1 to change the transparency. The input voltage of the electric control module 3 is lower than the human body safety voltage, the connecting circuit of the power module and the electric control module is safe, and the safety of personnel in the vehicle can be improved.

Optionally, the glazing 1 is electrochromic glazing.

Specifically, the electrochromic glass can be used as vehicle window glass of a vehicle to change transparency when the vehicle is powered on and powered off, the electrochromic glass is transparent when the vehicle is powered on, and is opaque when the vehicle is powered off, so that different requirements of people in the vehicle on transparency and opacity of the glass are met.

The vehicle window glass control system and the vehicle provided by the embodiment comprise vehicle window glass, a position detection module and an electric control module, when the position detection module detects that the vehicle window glass is not completely closed, the electric control module can output control voltage with a zero voltage value to the vehicle window glass according to a received vehicle window glass position signal which represents that the vehicle window glass is not completely closed, and therefore the safety of the vehicle window glass control system on the transparency control of the vehicle window glass and the safety of people in the vehicle are improved.
