摘　　要：国内缺少集成式电液制动(I-EHB)系统的检测仪器,因此研发一套基于LabVIEW的I-EHB检测系统。针对I-EHB性能测试需要模拟的工况多的问题,设计一套基于CAN总线的ECU通信系统,能够配置控制I-EHB内部ECU电磁阀、电机所有动作的报文,自动完成报文与具体控制目标的对应、转换成报文帧格式、对对应地址值数据修改的动作。该检测系统采用电缸模拟脚踩刹车动作,通过通信模块控制I-EHB动作,利用测试管路模拟实车工况,用高精度传感器采集I-EHB制动状态,并在软件上实时显示。针对I-EHB的3种工作状态,分别制定基础制动试验,对某I-EHB进行测试。结果表明:所设计的检测系统测试结果曲线及特征点值均符合预期,能够满足I-EHB性能检测台的稳定性与可靠性需求。Based on the lack of integrated electro-hydraulic braking(I-EHB)testing instruments in China,an I-EHB detection system based on LabVIEW was developed.In view of the fact that the performance test of I-EHB needs to simulate many working conditions,an ECU communication system based on CAN bus was designed,which could be used to configure the messages to control all actions of ECU solenoid valve and motor in I-EHB,and the actions of correspondence between messages and specific control targets,conversion into message frame format,and modification of corresponding address value could be automatically completed.In the detection system,the electric cylinder was adopted to simulate the foot brake action,the I-EHB action was controlled through the communication module,the test pipeline was used to simulate the real vehicle working condition,the high-precision sensor was used to collect the I-EHB braking status,and it was displayed in real time on the software.According to the three working states of I-EHB,the basic braking tests were made respectively,and the products of an automobile company were tested.The results show that the test result curve and characteristic point value of the designed testing system meet the expectation,and the stability and reliability requirements of the I-EHB performance testing platform can be meet.
