A Study of Electronic Control Unit (ECU) Design and Hybrid Simulation for Motorcycle Engine 2008-01-1736

Considering the structure and performance characteristics of an engine, taking LJ377MV motorcycle engine for an example, the paper studies its hardware and software design ECU. Using hybrid simulation, the MAP of ignition and fuel injection are obtained based on mathematical model of engine, then taking them into the ECU. After getting the fuel injection quantity and the ignition angle, they were put into the simulation code of engine work process as initial conditions. Then, the power and torque of different working condition are obtained by calculating, and the result is compared with the reference experimental data. The result shows the simulation model is satisfactory. Through simulation experiment, verifying the dynamic circuit electric control system of ignition and fuel injection is correct and reliable. This paper provided a research method to shorten the product development cycle of electronic control unit and reduce the cost of research and development.
