| 摘 要： | 针对混合动力电动汽车（hybrid electric vehicle,HEV）控制系统CAN总线在调度信号时的不确定性和低优先级信号易死锁等问题,设计了基于截止期公差递增区分策略的混合调度算法进行优先级分配,并应用于HEV控制系统中。最后利用Truetime和dSPACE硬件在环平台进行实例HEV的CAN测试和功能仿真分析,验证了该混合调度算法的有效性,从而为研究新能源汽车（包括纯电动汽车、插电式混合动力汽车）的CAN总线数据通信提供一种新方法。

| Abstract: | Aiming at the problems of uncertainty in scheduling periodic signals and the permanent block of lower priority message in the controller area network（CAN） of hybrid electric vehicle（HEV） control system,a hybrid schedul-ing algorithm was proposed,in which a tolerance increased strategy of deadline was used to assign priority the message.The hybrid scheduling algorithm was applied to the CAN of HEV control system.Finally,based on the Truetime and hardware in the loop simulation method,the performance of HEV control system was analyzed.The simulation results showed the effectiveness of the hybrid scheduling algorithm. |
