摘要
以四轮独立转向时车载CAN网络时间同步过程为背景,运用平均时间同步(average timeSynch,ATS)算法对分布式轮毂电机时间同步性能进行收敛推演;证明了在车载CAN网络中使用ATS算法会使分布式转向轮毂电机时间同步失效;为抑制四轮独立转向过程中时间同步的发散性,对ATS算法进行修正改进,并进行了仿真试验。研究结果证明:改进后的ATS算法在四轮独立转向过程中会有效抑制四轮独立转向时间同步的发散性。
Based on the time synchronization process of on-board can network during four-wheel independent steering,the time synchronization performance of distributed hub motor is deduced by using average time synchronization(ATS)algorithm.It is proved that the use of ATS algorithm in vehicle can network will invalidate the time synchronization of distributed steering wheel hub motor.In order to suppress the divergence of time synchronization in the process of four-wheel independent steering,the ATS algorithm is modified and improved,and conduct the simulation test.The results show that the improved ATS algorithm can effectively suppress the divergence of four-wheel independent steering time synchronization in the process of four-wheel independent steering.
