Should Auto Hold Be Turned Off When Reversing?
1 Answers
There is no need to turn off the auto hold when reversing. Below is relevant information about the parking brake system: System: The Electronic Parking Brake (EPB: Electrical-Park-Brake) integrates temporary braking during driving with long-term parking braking, achieving parking brake functionality through electronic control. The electronic parking brake uses electronic control to implement parking braking, operating on the same principle as mechanical handbrakes—both rely on friction between brake discs and pads to achieve parking brake control. The only difference is that the control method shifts from a mechanical handbrake lever to an electronic button. Advantages: Traditional handbrakes require the driver to manually release the brake or skillfully coordinate the throttle and clutch for smooth starts on slopes. In contrast, the AUTOHOLD automatic parking function provides precise braking force through a slope sensor controlled by the system. During startup, the parking control unit calculates information from sensors such as clutch distance, clutch engagement speed, and throttle pedal position.
