摘要： 为解决现有电子液压制动（EHB）系统功能扩展性较差、无法拓展至更大车载质量的 三轴越野汽车的问题，文章通过对某型越野汽车 EHB 系统的系统压力、蓄能器工作容积以及 制动器缸径等关键参数的选型计算，设计匹配了该车的 EHB 系统。该系统实现了整车各轮边 制动力可调，并具有可靠的双回路安全冗余设计，可对制动过程中的系统压力进行调节，不 仅缩短了制动响应时间，还具有良好的扩展性，可满足更大车载质量的越野汽车的制动需求。 经对该系统进行实车测试，制动系统性能指标均满足国内外法规的要求。

Abstract: To address the issue that the existing electronic hydraulic braking (EHB) system has limited functional expandability and can't be extended to three-axle off-road vehicle with larger load capacity. By selecting and calculating the key parameters such as the system pressure of a certain off-road vehicle's EHB system in this paper, the working volume of the accumulator, and the diameter of the brake cylinder, the EHB system of this vehicle is designed and matched. This system achieves adjustable braking force for each wheel end of the vehicle and features a reliable dual-loop safety redundancy design. It can regulate the system pressure during the braking process, not only shortening the braking response time but also having good scalability, and can meet the braking requirements of off-road vehicle with larger load capacity. After conducting real vehicle tests on this system, all the performance indicators of the braking system meets the requirements of domestic and international regulations.
