Problems solved by technology

[0003] However, in the existing electronic parking brake system, the parking is realized through electricity. When the circuit fails, the vehicle cannot be braked or released.
Moreover, in the existing electronic parking brake system, the components are connected by gas paths, and there are many gas paths, which are cumbersome to connect and take up a lot of space. Probability, reduces the transmission efficiency, makes the braking delay and not accurate enough

Abstract

The present invention provides a pneumatic parking system and its parking control method, comprising an air storage tank, an integrated valve, a quick release valve and a brake chamber, wherein the integrated valve consists of a manual valve, a first The solenoid valve and the second solenoid valve are integrated into one body; the manual valve is connected with the air path of the gas storage tank, connected with the gas path of the quick release valve, and connected with the atmosphere; the first solenoid valve is connected with the atmosphere; the second solenoid valve is connected with the gas path of the quick release valve. The quick release valve is connected with the air circuit of the brake chamber and connected with the atmosphere; the manual valve, the first solenoid valve and the second solenoid valve are operated to realize the connection and cut-off of the system passage, and complete the braking chamber. Air supply, release and pressure maintenance. The air pressure parking system of the invention improves the braking transmission efficiency and ensures driving safety.

Description

technical field [0001] The invention relates to the field of parking brakes, in particular to a pneumatic parking system and a parking control method thereof. Background technique [0002] The electronic parking brake system (EPB Electrical Park Brake) integrates the functions of temporary parking during driving and long-term parking after parking, and realizes parking by electronic control to improve the active safety of the car active safety control system. The system has advantages such as stop and go, auxiliary starting on slopes, emergency auxiliary braking, etc., and has a good application prospect. [0003] However, in the existing electronic parking brake system, the parking is realized by electricity, and when the circuit breaks down, the vehicle cannot be braked or the brake is released. Moreover, in the existing electronic parking brake system, the components are connected by gas paths, and there are many gas paths, which are cumbersome to connect and take up a ...
