Vehicular CAN FD network-oriented signal grouping and packaging method

The invention discloses a vehicular CAN FD network-oriented signal grouping and packaging method. The vehicular CAN FD network-oriented signal grouping and packaging method comprises the following steps of: (1), grouping signals according to periods of the signals, and arranging signal groups obtained by grouping according to the periods in a ascending sequence; (2), sequentially packaging the signal groups in messages according to an idle bandwidth evaluation index and an integer linear programming algorithm so as to obtain message sets; and (3), distributing priorities to the message sets obtained after packaging according to a time robustness ascending sequence, furthermore, performing scheduling analysis, and, if the message sets obtained after packaging cannot be scheduled, splitting the message sets obtained after packaging so as to improve the schedulability of the whole message sets till the message sets obtained after packaging can be scheduled or no message can be split. By means of the vehicular CAN FD network-oriented signal grouping and packaging method disclosed by the invention, on the premise that the schedulability of a CAN FD network is ensured, optimization of the network bandwidth utilization rate can be realized.
