气压ABS架构下的商用车线控制动方案设计与试验OA

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.
