Abstract

The invention discloses an electric control hydraulic parking braking system and a control method. The electric control hydraulic parking braking system comprises a parking braking oil path and a service braking oil path which are integrated. The electric control hydraulic parking braking system is characterized in that a power supply, a parking switch and one or more parking control valves are respectively connected with an electronic control unit (ECU), and when receiving a signal from the parking switch, the electronic control unit (ECU) treats and controls the opening / closing motion of the parking control valves. Through the adoption of the electric control hydraulic parking braking system and the control method provided by the embodiment of the invention, varied practical problems that a parking handle (manual brake) is frequently pulled up on and put when a driver parks a vehicle and starts the vehicle can be solved; in addition, the electric control hydraulic parking braking system disclosed by the invention is reasonable in design, simple in structure, and convenient, and safe and reliable to park, the manual park does not need to be regulated, and the vehicle service cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, and in particular relates to an electronically controlled hydraulic parking braking system and a control method. Background technique [0002] Parking brake is a temporary parking or long-term parking used to stabilize the vehicle, to avoid accidents caused by rolling when the vehicle is on a sloping road or parking. The type of parking brake refers to the operation mode of the parking brake. Now the operation mode of the parking brake on passenger cars can be divided into three types: hand brake, foot brake and electronic parking. [0003] The commonly used traditional mechanical parking method is referred to as handbrake. It has a simple structure and low manufacturing cost, but it takes up a lot of space. In addition, long-term use of the handbrake will cause plastic deformation of the brake cable. Since this deformation is irreversible, long-term use It will reduce the effectivene...
