What Causes Automatic Door Locking?
2 Answers
It is due to the activation of the automatic door locking feature while driving. Here are some details about automatic door locking: 1. Automatic door locking while driving, also known as speed-sensing auto-lock, is an electronic device. 2. When the vehicle reaches a preset speed (usually set by the manufacturer, typically between 10 km/h and 20 km/h), the lock button will automatically engage to prevent accidental door opening. This is the most common method of automatic door locking used in many vehicle models. 3. There are other methods of automatic door locking: For example, when the transmission is shifted into D (Drive) gear, the lock button will automatically engage to prevent accidental door opening. This method is used in some models of Chevrolet and Buick. Another method is when the driver steps on the brake while driving, the doors will automatically lock. This method is generally found in domestic cars or some low-end models.
The automatic locking of car doors while driving is primarily designed for safety reasons. Engineers have integrated a speed detection system into the vehicle's electronics, so when you start driving and accelerate to between 15 to 20 kilometers per hour, the electronic control module triggers all doors to lock automatically. This effectively prevents the risk of doors accidentally opening while in motion—such as if a curious child pulls the handle, which could lead to a serious accident. Almost all modern vehicles come with this feature enabled by default, and you can adjust settings like turning the auto-lock on or off via the central control screen. Additionally, this mechanism serves as an anti-theft measure, preventing thieves from opening doors when the car is parked. If the function isn't working, I would first check the settings and the speed sensor, and not wait until high speeds to test it.
