【Abstract】 Aiming at the challenges of high cost, high energy consumption and high safety risk faced by traditional engine bench experiment teaching, a virtual engine experiment teaching system with real ECU closed-loop control was developed based on the hardware-in-the-loop technology of diesel engine. The signal simulation of engine sensor and the signal acquisition of actuator were designed and realized by FPGA hardware. The virtual engine and ECU closed-loop control were realized by connecting the load board with the real ECU. In order to support the virtual engine experimental teaching, the software modules including experimental management, virtual instrument and monitoring interface, data management, theory and experimental guidance manual are developed. The human-computer interaction hardware equipment of the virtual engine experimental teaching system is designed, and the system is used for experimental test and teaching application. The results show that the designed virtual engine experimental teaching system can provide practical support for the teaching of engine experimental courses.更多还原
