Working Principle of Auto Switch

2021-08-12
Electric Windows are pulled by reversible motors, and each motor is protected by a built-in circuit breaker. If the window switch is left open for too long (the window is blocked or after the upper and lower limits), the circuit breaker disconnects the circuit and automatically resets when it cools.
When the ignition switch is in the RUN or START position, or 10 minutes after the OFF position, the integrated controller supplies the coil voltage of the electric window relay. The relay contact closes, and the voltage goes to the main switch of the electric window and the window switch in the door.
Driver's window
When the ignition Switch is in the RUN or START position, or 10 minutes after the OFF position, the integrated controller will Switch on the voltage of the electric window relay. The relay contact is closed, and the voltage goes to the driver side electric window Switch. When the Switch is in the UP position, the voltage goes through the main electric window motor, and the motor goes through the driver Auto Switch loopback by rail. When the switch is adjusted in the UP position, the electric window motor will push the window UP all the time; In the DOWN position, the direction of the voltage is reversed, and when the DOWN position is held, the motor moves the window DOWN.
Automatic descent (driver window)
When the ignition Switch is in the RUN or START position, the voltage is connected to the electric window relay coil through the integrated controller, and the contact of the electric window relay is closed. The voltage is connected to the driver's electric window Switch. When the driver's Auto Switch is adjusted to the Auto Down position, the voltage is connected to the motor of the electric window through the driver's window Switch. The controller will receive a pulse from the pulse input signal, when the window is completely down, the motor stops, the pulse signal will no longer occur, after the controller sensing side of the pulse input, the voltage will no longer be sent to the electric window motor.
The passenger window
After the ignition Switch is turned to the OFF position for 10 minutes after RUN, the voltage is transmitted to the electric window relay coil by the integrated controller. The contact of the electric window relay closes, and the voltage is supplied to the Auto Switch of all the Windows. When the main Switch of the main instrument panel is opened, the passenger window can be controlled by the door Switch or the main instrument panel.
When the right front door and window switch to UP, the voltage to the right front electric window motor, motor through the right front electric window switch and the main instrument panel switch contact to achieve iron, the window has been UP until the release of UP position, such as the right front door and window switch to DOWN position, the voltage to the opposite direction; The window moves DOWN until it is released DOWN, and the other Windows operate in a similar manner.
