Abstract

The invention provides a commercial vehicle and a commercial vehicle electronic parking brake system. According to the commercial vehicle, an air storage unit is connected with a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve through air channels; the first electromagnetic valve is electrically connected with an electronic control unit (ECU) and is respectively connected with a trailer valve and a rear axle module gas circuit; the second electromagnetic valve is electrically connected with the control switch and is connected with a trailer valve gas circuit; the third electromagnetic valve is electrically connected with the control switch, the third electromagnetic valve is respectively connected with the middle and rear axle diaphragm spring brake chamber and a trailer valve gas circuit, and the rear axle module is connected with the middle and rear axle diaphragm spring brake chamber gas circuit; and the fourth electromagnetic valve is electrically connected with the control switch and is connected with a trailer valve gas circuit. According to the system, parking braking of the commercial vehicle is achieved in an electronic control mode, and the functions of parking braking, automatic parking, hill starting, emergency braking, trailer position detection, trailer independent braking and the like in the vehicle running process are integrated.

Description

technical field [0001] The invention relates to the technical field of automobile chassis, in particular to a commercial vehicle and an electronic parking brake system for the commercial vehicle. Background technique [0002] With the continuous advancement of automotive electronic technology, electronic control technology is more and more widely used in automobiles, and the original mechanical control system has gradually developed into an electronic control system. In line with the tide of development, the traditional manual mechanical parking has also begun to develop into an electronic parking system (EPB). Compared with the traditional parking system, the electronic parking brake system has many advantages, such as easy operation, optimized cab space, and more safety. [0003] At present, most commercial vehicles use manual mechanical parking, lacking an electronic parking brake system that integrates multiple functions. [0004] In view of the above-mentioned defects...
