Working principle of lifting window:
1. The key sends out a weak radio wave, the car antenna receives the radio wave signal, the electronic control unit recognizes the signal code, and then the actuator (motor or electromagnetic coil) of the system performs the opening/closing action. Long press the unlock button of the remote control, and four glasses will automatically drop. Press the lock button for a long time, and the four glasses will automatically rise.
2. Whether controlled by intelligent key or mechanical button, the one-button lifting of the window generally has the function of "preventing hands from being pinched". In the process of automatic closing, if an object is caught between the glass and the window frame, the closing operation of the window will automatically stop and return to the initial state halfway, otherwise it may cause the danger of pinching hands.
3. Each power window has a power window control module (ECM). When the power window control switch is pressed, the ECM begins to receive the signal of the control switch. If the switch is pressed for less than 0.5 second, the ECM will control the window to be fully opened or fully closed. If the switch is pressed for more than 0.5 seconds, the ECM will always turn on the power window motor, and the window will stop rising or falling only when the switch is turned off.
