FlexRay dynamic segment information scheduling method based on polling schedulers

The invention relates to the technical field of automobile communication, in particular to a FlexRay dynamic segment information scheduling method based on polling schedulers. According to the scheduling method, a medium access mechanism of the flexible time division multiple access of a FlexRay dynamic segment is adopted, the multiple polling schedulers with different operating parameters and corresponding FlexRay network parameters are built, optimal parameters of the polling schedulers are obtained, optimal and feasible dynamic segment information grouping sets are built, and the polling schedulers with the optimal parameters are created for the information grouping sets respectively; when the polling schedulers are in the activated state, corresponding dynamic segment information is selected according to the internal priority to be transmitted; when the polling schedulers are in the inactive state, transmitting of any internal dynamic segment information is stopped. According to the FlexRay dynamic segment information scheduling method, random transmitting of the dynamic segment information of the polling schedulers is converted into controlled orderly transmitting, the minimum FlexRay dynamic segment length is accordingly guaranteed, it is guaranteed that all dynamic segment information can be completely transmitted within a time limit, and maximum utilization of the dynamic segment network bandwidth is guaranteed.
