【摘要】 针对CAN总线不能有效处理时间触发的周期信息和事件触发信息共网实时性通信问题,考虑网络设计、调度的灵活性,将FTTCAN(flexible time triggered CAN)引入汽车动力控制系统,与车身控制系统低速CAN互联组建车载网络,给出了FTTCAN同步相调度中周期信息调度表SchT的制定方法,通过分析车载网络系统实时性与确定性,验证了该方案的可行性和优越性。更多还原

【Abstract】 Controller area network(CAN) can not deal with event-triggered traffic and time-triggered traffic simultaneously and efficiently in real time system.Considering the flexibility of design and schedule,flexible time triggered CAN(FTTCAN) was introduced to manage the power transmission system in vehicle and build up in-vehicle networks with CAN by linking with gateway.The method of allot messages in scheduling table(SchT) in synchronous phase was introduced.The analysis results of system such as real time performance and dependability verified the proposed scheme was feasible and showed perfect performance.更多还原
