What is Electronic parking brake？
While most automatic transmission vehicles have parking brakes, it is often not engaged by drivers when parking. However, it is recommended to use it, as the parking pawl in the gearbox could fail due to stress or another vehicle striking the car, causing the car to roll. Also, regular use of the parking brake reduces the chance of corrosion by keeping the cables in-motion.
The parking brake in most vehicles is still completely mechanical. Traditionally engaged by pulling a lever, the cables manually engage part of the car’s braking system, usually the rear disk or drum brakes. The mechanical nature allows the driver to apply the brake even if the main hydraulic brake system fails.
An electronic parking brake (EPB), also known as an electric park brake in North America, is an electronically controlled parking brake, whereby the driver activates the holding mechanism with a button and the brake pads are electrically applied to the rear wheels. This is accomplished by an electronic control unit (ECU) and an actuator mechanism. There are two mechanisms that are currently in production, Cable puller systems and Caliper integrated systems. EPB systems can be considered a subset of Brake-by-wire technology.
