基于CANoe的混合动力电动车TTCAN建模与仿真

针对混合动力电动车控制器网络的特点,使用对独占窗和仲裁窗分别调度的系统矩阵设计方法设计了时间触发CAN总线(TTCAN)协议。在对网络仿真系统CANoe进行二次开发、增加应用层和会话层模型的基础上,对所设计协议进行了仿真分析,并利用实车试验对仿真结果进行验证。结果表明:周期型信息实时性好、抖动小;事件型信息的实时性受仲裁窗调度的影响较大。

Modelling and Simulation of TTCAN for Hybrid Electric Vehicles Based on CANoe

By using system matrix design method for the system with its exclusive and arbitration windows separately scheduled,a time-triggered controller area network(TTCAN) protocol for hybrid electric vehicle is designed.After adding application and session layers in network simulation system CANoe,the designed protocol is simulated and analyzed with the results verified by real vehicle testing.It is shown that the real-time performance of periodic message is desirable with less fluttering and that of event message is significantly influenced by arbitration window scheduling.
