【摘要】 iBooster作为电子液压制动系统（EHB）的核心零部件，因其结构紧凑、性能稳定可靠、技术成熟等优点，成为了目前线控制动的主流方案，广泛的应用于新能源汽车以及传统燃油车中。目前iBooster的ECU普遍基于V模型开发，而测试流程复杂繁琐，占据了开发的大半部分。为了优化测试流程，提高测试效率，通过分析iBooster的结构和原理，搭建了一套硬件在环仿真测试系统。在没有实车的条件下，利用测试台架，通过故障注入测试，验证发生故障时EHB系统的功能降级策略；通过主动建压响应特性测试，测试iBooster的响应速度和建压精度；通过模拟复杂制动工况，验证iBooster的控压逻辑。测试结果表明，该套系统能够满足iBooster的测试需求，有效提高测试效率，缩短开发周期。更多还原

【Abstract】 As the core component of the electronic hydraulic brake(EHB) system,the iBooster has become the mainstream solution of the current brake-by-wire because of its compact structure,stable and reliable performance,and mature technology. It is widely used in new energy vehicles and traditional fuel vehicles. At present,the ECU of iBooster is generally developed based on V model,and the test process is complicated and cumbersome,accounting for most of the development. In order to optimize the test process and improve the test efficiency,a hardware-in-the-loop simulation test system is built by analyzing the structure and principle of iBooster. Under the condition of no real vehicle,the fault injection test is carried out by using the test bench to verify the function degradation strategy of EHB system when the fault occurs. The response speed and pressure building accuracy of iBooster are tested by active pressure building response characteristic test. The pressure control logic of iBooster is verified by simulating complex braking conditions. The test results show that this system can meet the test requirements of iBooster,effectively improve the test efficiency and shorten the development cycle.更多还原
