摘　　要：针对事件触发CAN实时性与确定性无法满足独立驱动电动汽车动力系统应用问题,以自主研发的双电机独立驱动电动汽车为对象,构建基于TTCAN协议的网络化控制模型,利用AL算法设计信息调度策略,并对其信息传输实时性、延迟、周期抖动及带宽利用率等系统特性进行理论分析与实验验证.结果表明,作者设计的TTCAN方案有效改善了系统通信实时性与确定性.The event-triggered CAN is not real-time and deterministic enough as the underlying network for powertrain system of independent driving electric vehicle （EV）. The time-triggered CAN （TTCAN） protocol was adopted for powertrain system of a self-developed 2-wheel independent driving EV. Then the scheduling strategy was promoted based on AL algorithm.The performance of real-time capability, transmission delay, periodic jitter and bandwidth utilization were theoretically analyzed and experimentally tested. The results show that theprotocol can effectively improve the real-time capability and determinacy of system communication.
