How to Use the Anti-Pinch Function of Power Windows?
3 Answers
The anti-pinch function of car power windows is activated in one-touch mode by holding the window-up button until the window reaches the top and then releasing it. Below is how the anti-pinch function works: 1. The anti-pinch function is a safety feature in vehicles that automatically stops the power window or reverses its direction (from up to down) when resistance is encountered during closing, preventing injuries and ensuring the safety of passengers. 2. The anti-pinch mechanism involves installing a current sensor, where a Hall sensor continuously monitors the motor's speed. When the power window is closing, if the motor's speed slows down, the Hall sensor detects the change and reports it to the ECU. The ECU then instructs the relay to reverse the current, causing the motor to stop or reverse (lowering the window), thus stopping or lowering the window and providing an anti-pinch effect.
I've always been a big fan of automotive technology, and the anti-pinch feature for power windows is truly a safety blessing. It's super easy to use: when you press the window switch to raise the window, the system automatically detects resistance. If something or someone gets pinched, like a hand or pet, the window immediately stops or even reverses slightly to an open position. Most cars have this feature enabled by default, requiring no extra setup. I often test it in parking lots with a small soft pad – if it doesn't reverse, it's time to visit the shop to check the sensors or wiring. Keeping the window tracks clean is crucial to prevent dust buildup from interfering with detection. This feature significantly reduces accidents, especially when kids are in the car – I always emphasize teaching them not to touch the window edges. Regular circuit maintenance is key to avoid failure due to aging issues.
Safe driving is one of my core values, and the anti-pinch function of electric windows should never be overlooked. When operating, hold the up button to raise the window—if there's any obstruction, it will automatically reverse to prevent injury. I recommend all car owners test this feature after purchasing a new car by using a paper cup or toy to check responsiveness. However, don’t rely solely on it; educate passengers not to reach out during window operation. If the function fails, the window may not retract, so check the fuse or relay for faults. Keep the tracks lubricated to prevent jamming. This mechanism works based on resistance detection—the system triggers automatically when monitoring changes in motor load. In practice, adding in-car rules like keeping children away from windows can further enhance safety. Remember to stop using it immediately if a malfunction occurs and have it professionally adjusted to avoid risks.
