What does the anti-pinch function of the Equinox window mean?

[McNadia]

The anti-pinch function of the window is a safety feature on the vehicle, which means that when the electric window glass is closing and encounters resistance, it will automatically stop or change the upward movement of the glass to a downward movement, thereby preventing injury and protecting the safety of the occupants in the vehicle. Working principle of the anti-pinch function: Anti-pinch means installing a set of current sensors, with a Hall sensor constantly monitoring the speed of the motor. When the electric window rises, the speed of the electric motor slows down. When the Hall sensor detects a change in speed, it reports the information to the ECU. The ECU then sends an instruction to the relay, and the circuit reverses the current, causing the motor to stop or reverse (lowering the window), thus stopping or lowering the window and achieving the anti-pinch function. Advantages of anti-pinch glass: The advantage of anti-pinch glass is that it can prevent children from sticking their hands outside the window and accidentally getting pinched, making it part of the vehicle's passive safety features.
