Based on ABS(Antilock brake system) architecture of commercial vehicles

a simple structure and cost-effective implementation scheme of line control for commercial vehicles is proposed. According to the existing commercial vehicle ABS system

an IAEB(Intellgent electronic brake systems) electromagnetic relay valve which can realize accurate closed-loop control of pressure is designed

and a wire control system is designed based on this valve. At the same time

the braking performance of the wire control system is analyzed by testing the control precision and braking response time of the test vehicle. The test results show that the wire control system has the same wire control effect as the existing electronic brake systems (EBS)

and the structure is simpler. Moreover

it can be exchanged and upgraded directly on the existing system without major changes

which greatly reduces the cost of promoting the line control system of the vehicle factory

and is conducive to the rapid realization of intelligent driving in the field of commercial vehicles.
