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.
