Problems solved by technology

[0006] 1. The parking brake can only realize the safe parking of the vehicle on a 20% slope without a load. For vehicles that need to start on a slope with a large angle, it cannot realize the parking on the slope and the auxiliary control of the slope start, and it is difficult to cope with complex road conditions. use
[0007] 2. When the vehicle is driving in urban road conditions, there are many red street lights and frequent parking will cause the pressure of the air source of the vehicle's air storage tank to be tense. The separate control of the parking brake system and the service brake system cannot realize the efficient use of the air source pressure.

Abstract

The invention discloses an integrated automatic parking braking device. The integrated automatic parking braking device comprises an electric control unit (ECU) provided with a vehicle state information input port (90), and is characterized by further comprising a parking braking unit (1) electrically connected with the ECU, a rear driving braking unit (2) and a front driving braking unit (3). The integrated automatic parking braking device has high large-angle slope parking capacity and low consumption of compressed air in a braking system.

Description

[0001] technical field [0002] The invention belongs to the technical field of brake systems for medium and heavy vehicles, in particular to an integrated automatic parking brake device based on a service brake system and a parking brake system. Background technique [0003] At present, the parking brake device of medium and heavy vehicles adopts an air pressure parking brake device. This kind of air pressure brake device adopts the principle of "air break brake" to generate parking brake force by exhausting the parking brake chamber. The traditional pneumatic brake device uses a manual joystick, and the operation process is cumbersome, and inexperienced drivers are prone to slipping. [0004] In order to solve the problems of manual operation, the Chinese Utility Model Patent Application Publication "Air Pressure Adjustable Electronic Parking Brake System" (publication number CN 103407439 A, publication date November 27, 2013) discloses an air pressure adjustable electroni...
