1：What is it used for?
The EPB allows for one-touch activation or release of the parking brake, making it more convenient and effortless compared to the traditional handbrake.
2：Advantages:
• In certain vehicle models, the EPB automatically releases when the accelerator pedal is pressed, preventing issues with the braking system caused by driving with the handbrake engaged.
• The elimination of the traditional handbrake lever creates space for features like storage compartments.
• EPB helps avoid incomplete engagement of the handbrake, which can lead to vehicle rolling when using the traditional handbrake.
3：Misconceptions:
• Operating methods may vary among different vehicle models, so please refer to the owner's manual for instructions.
• It may take time to develop a habit of using the EPB, and there is a possibility of forgetting to engage it after parking.
• Some vehicle models may produce sounds during the activation or release of the EPB, which is normal and nothing to worry about.
4：Technical Principle:
The EPB (Electrical Park Brake) replaces the mechanical lever and tire steel cables of traditional parking brakes, providing better assistance to the driver. Essentially, it replaces the traditional handbrake lever with an electronic button. Conventional parking brakes rely on the force of spring chambers to engage. When the parking brake (hand valve) is activated, it releases compressed air from the spring chambers, allowing the spring force to act on the wheel brakes and engage the parking brake. The EPB replaces the conventional hand valve and relay valves with electronic control units and solenoid valves, incorporating other systems and logic to achieve functionality.

Auto Hold Function:
The traditional handbrake requires the driver to manually release it or coordinate throttle and clutch to smoothly start on an incline. However, the Auto Hold function automatically applies the precise parking force determined by the controller based on the slope sensor. When starting, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. If the driving force exceeds the resistance, the auto hold system automatically releases the parking brake, allowing the vehicle to start smoothly. Even in stop-and-go city driving, once you activate the Auto Hold function, it engages the corresponding automatic parking brake function. The intelligent Auto Hold function applies the four-wheel brakes automatically when the vehicle is stopped at a red light or on an incline, even when in Drive (D) or Neutral (N). You don't have to continuously press the brake pedal or use the handbrake; the vehicle remains stationary. To release the stationary state, simply lightly tap the accelerator to disengage the brake.
