Research and Implementation of Automated Hil Simulation Test Platform for Ecu of Automotive Engine

Abstract

In order to help automobile factory finding a simple and effective automatic testing equipment to replace the heavy and repetitive manual testing work of test engineers, so that test engineers can concentrate on improving the function and design of test system, firstly, the hardware in the Loop (HIL) simulation test and automation test of the engine electronic control unit (ECU) are deeply studied. Based on the experience accumulated in the past, the possibility analysis and technical evaluation of HIL simulation test, automation test and the real-time requirement of the ECU simulation test are conducted in detail. Then, aiming at the current testing tasks, combined with the commonly used HIL testing methods and technologies in the industry, a new software and hardware platform is put forward to realize the automatic testing program of automotive engine ECU function, which fully meets all the functional and technical requirements of the demand. The results show that the application of this automatic ECU real-time simulation test platform in the development of ECU of hybrid engine proves that it fully meets the actual needs. It can be seen that the ECU development cycle of a hybrid electric vehicle engine will be greatly shortened and the development cost will be saved in combination with the application of the platform.
