Abstract

The invention discloses a service braking system based on intelligent hill-start assist. The service braking system is easy to operate and good in safety and comprises a first gas storage tank (1), a foot barking valve (4) and a service braking gas chamber (8) which are communicated through gas circuits; the service braking system further comprises a second gas storage tank (3), a differential-type relay valve (5), a magnetic valve (9), a first three-way valve (61), a hill-start assist controller (2) and a gas pressure sensor (11); a first control gas port (541) of the differential-type relay valve (5) is connected with a gas outlet of the foot barking valve (4) through a gas circuit, a gas inlet (51) of the differential-type relay valve (5) is connected with the second gas storage tank (3) through a gas circuit, a gas outlet (52) of the differential-type relay valve (5) is connected with the service braking gas chamber (8) through a gas circuit, a second control gas port (542) of the differential-type relay valve (5) is connected with the second gas storage tank (3) through a gas circuit by means of the magnetic valve (9), and the gas pressure sensor (11) is arranged on the gas circuit between the gas outlet of the differential-type relay valve (5) and the service braking gas chamber (8).

Description

technical field [0001] The invention belongs to the technical field of automobile braking devices, in particular to a service braking system based on intelligent slope start assistance with simple operation and good safety. Background technique [0002] At present, the service brake device of medium and heavy vehicles adopts a pneumatic brake device, and the service brake air chamber is inflated through the foot brake valve to generate service brake. For traditional vehicles, when starting uphill, the driver's control process is complicated, and the vehicle is prone to slipping backwards. When starting uphill frequently, improper handling will aggravate the wear of the transmission system and brakes. [0003] The existing hill start assist device, such as Chinese utility model patent CN201320138667.9 (application number: 201320138667.9, publication date: 2013.08.28), this patent installs a two-position two-way solenoid valve in the braking circuit. First, the The small orif...
