Embodiment
[0034] For many CAN bus networks, at first adopt the method in the step (1) of the present invention respectively, calculate the reference cycle length N of each CAN network bus j , and then calculate the length N of each reference cycle on the respective bus j The maximum number of messages S that can be sent j :
[0035] S j =N j / dT j -1
[0036] Among them, dT j The time consumption required for sending the message of the jth CAN bus in the multi-CAN bus can be taken as an empirical value determined through experiments;
[0037] Calculate the length N of each reference cycle on each CAN bus j , the actual number of messages to be sent S1 j :
[0038]
[0039] in, is the i-th periodic message Mi on the j-th CAN bus j sending cycle, n j is the number of periodic messages on the jth CAN bus, for rounding operation;
[0040] According to the actual situation of the multi-CAN bus network, the number of messages S2 required to send event-type information is re...
