Solution for Electronic Parking Brake (EPB)

The full name of Electronic Park Brak in English is Electrical Park Brake or EPB for short. It uses wire control technology to integrate temporary braking during driving and long-term braking after parking, and the parking system is realized by electronic control. Dynamic technology. The EPB system removes the handle or pedals and other mechanical devices of the ordinary mechanical parking brake system and controls the parking brake through an EPB switch (usually designed as button P). This system not only realizes the parking brake Electronic control, while the EPB control unit is connected to the ESP system through a data bus to realize the vehicle’s automatic stop fixed function and dynamic emergency braking.

 

 

The Working Principle of  the EPB

The parking function of EPB is mainly realized by the transmission of telex signals, and the built-in ECU sends commands to drive the calipers to perform related actions. Its main signal interaction consists of the following aspects: electronic parking brake control unit, combination instrument EPB related display symbols, EPB switch buttons; engine control unit; transmission control unit; airbag control unit; inclination sensor; actuator, etc. The basic working principle of EPB is the same as that of mechanical hand brakes and foot brakes. The parking brake is controlled by the friction generated by the brake disc and the brake pads, but the control method is changed from the previous mechanical hand brake lever or foot pedal to an electronic Button, so some people call it “electronic handbrake.”

 

How to Use EPB?

Activate or deactivate the parking function with a button. Starting EPB can be started under any conditions of the vehicle, even if it is pressed by mistake during the journey, the EPB function will be turned off immediately because the accelerator is still in the working position; if it is pressed during emergency braking, most EPB systems will additionally provide Stronger braking force is used to assist, and some models have the functions of electronic braking force distribution and speed limit stop.

How Kinmore Makes Improvement

A huge operation can be achieved by pressing a small button thanks to the micromotor supplies movement power. The motor is controlled by the computer to release the brake for the smooth start of the vehicle. It can also balance the sliding force generated by the parking on the slope, as well as compensate for the temperature difference gap between the brake disc and the friction plate. Kinmore provides professional and reliable micro-motors for the EPB system. It performs the braking function efficiently under different driving conditions and improves the safety of the EPB system.
