Hardware In-Loop Simulation (HILS) Design for Common Rail Oil System of Diesel Engine

Hardware in-loop simulation system (HILSS) is an important tool of electronic control system design. Based on the analyzing to the electronic control system of diesel engine, an HILSS was developed. The design of the simulation system includes hardware, software, communication system and engine model designing. For the using of CAN (controller area networks) protocol, all the inputs and outputs can be operated in PC. Thus the flexibility is developed while the system cost decreases. By using the HILSS to design and test the hardware and software of target system, the target system gained excellent reliability and durability, and the cost and period of development are largely decreased.
