摘　　要：提出了一体式电液复合制动系统结构,研究了非紧急/紧急制动工况的制动力协调控制策略。分析了采用一体式主缸的制动系统结构原理,提出了制动力基本控制逻辑。研究了非紧急制动工况下的再生制动力和液压制动力的分配策略;分析了触发防抱死制动系统的两种情形,提出了电液复合制动到纯液压的防抱死制动协调控制策略。利用xPC target搭建了硬件在环仿真试验台架,对非紧急/紧急制动工况进行了试验。试验结果表明,所提出的一体式电液复合制动系统和制动力控制策略能够满足能量回收和与防抱死制动协调控制的需求。An integrated electro-hydraulic brake system was proposed,and the coordinated control strategy of regenerative braking force and hydraulic braking force was studied under non-emergency/emergency braking conditions.The principle of the electric-hydraulic brake system with an integrated master cylinder was analyzed,and the basic control strategy for the two braking conditions was proposed.Brake force distribution strategy between regenerative braking force and hydraulic braking force under non-emergency condition was investigated.Two cases triggering the anti-lock braking system were presented.Cooperative control between electric-hydraulic brake and anti-lock brake using hydraulic braking force was studied with simplified control logic.Hardware-in-the-loop test bench was built using xPC target,and non-emergency/emergency braking tests were carried out.Test results show that the proposed integrated electro-hydraulic brake system and braking force cooperative control strategy can meet the braking energy recovery and coordination with the anti-lock brake control needs.
