ECU(Electronic Control Unit) is one of the most important parts in modern vehicles, and its stability and reliability are crucial to the safety of vehicles. In addition to ensuring the reliability of ECU control strategy, it is also necessary to improve the quality and efficiency of the production line. Therefore, ECU needs to be tested and detected in detail, and the traceability of data is guaranteed. Based on years of testing and development experience, Huahai technology has independently developed SIM-PLTE equipment, which covers EOL, FCT and ETE (endurance testing equipment). The controller under test covers VCU, BMS, MCU, ABS, EPS, ESC, ADAS, HCU, FCU, BCM, etc.
