What are the reasons for the failure of the automatic parking function?

[MacColeman]

The reasons for the failure of the automatic parking function: The parking brake lever cannot be fixed; the parking brake fails; the parking brake makes abnormal noises or is aging; the gap between the friction plate of the automatic parking system and the brake drum is too large, the friction plate and the brake drum are contaminated with oil or severely worn, the rivets are exposed, and the surface is hardened, causing slippage and failure; the parking brake shaft is severely worn, the gap is too large, and the parking brake lever is adjusted too long. Additional information: 1. Automatic parking function: The automatic parking function is a feature that allows the driver to avoid unnecessary vehicle sliding without the need for prolonged braking or activating the electronic parking brake. 2. Principle: The automatic parking function provides precise parking force through a slope sensor controlled by the controller. When starting the vehicle, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the running resistance, the parking brake is automatically released, enabling the car to start smoothly.
