Hardware-In-Loop Simulation of HEV System Based on CAN

以ISG型轻度混合动力系统为研究对象,构建了dSPACE环境下的混合动力系统硬件在环仿真实验平台,进行了基于CAN通信的混合动力系统动力总成控制器的硬件在环仿真实验,对混合动力系统启动、加速助力、匀速充电等不同工况的动态特性进行了仿真实验和分析。

Using the ISG type mild hybrid electric vehicle（HEV） as research object, a-Hardware- In-Loop simulation system of hybrid electric powertrain had been built by using dSPACE. A Hardware-In-Loop simulation experiment of hybrid electric powertrain control unit was carried out based on CAN, and the dynamic characteristics of hybrid electric powertrain was tested and analyzed under different working modes such as engine start-up, accelerating assist and battery charging at equable speed. The research lays a foundation for control strategy optimization of hybrid electric powertrain control unit.
