【摘要】:車載通信網絡管理(NM)系統(tǒng)的性能直接影響到汽車電子網絡通信安全.對OSEK NM中邏輯環(huán)機制實際運行狀態(tài)進行建模,建立各工作狀態(tài)間轉換模型;引入NM誘導報文和邏輯環(huán)不穩(wěn)定時間,定量分析OSEK NM邏輯環(huán)不穩(wěn)定工作狀態(tài),推導出度量邏輯環(huán)工作性能的計算公式;提出一種支持第二直接后繼的邏輯環(huán)建環(huán)機制,給出該機制下邏輯環(huán)的工作性能.實驗結果表明:相對于OSEK NM,支持第二直接后繼的建環(huán)機制不僅能夠提高車載NM的實時性,而且能有效降低NM對用戶報文傳輸?shù)牟涣加绊?
[Abstract]:The performance of vehicular communication network management (NM) system directly affects the communication security of automotive electronic network. The actual running state of logical loop mechanism in OSEK NM is modeled, and the transformation model of each working state is established. The NM induced packets and the unstable time of the logical loop are introduced to quantitatively analyze the unstable working state of the OSEK NM logical loop, and the calculation formula to measure the working performance of the logical loop is derived. In this paper, a mechanism supporting the second direct follow-on logical ring construction is proposed, and the working performance of the logical ring is given. The experimental results show that compared with the second direct successor mechanism supported by OSEK NM, the mechanism can not only improve the real-time performance of on-board NM, but also effectively reduce the adverse effect of NM on the transmission of user messages.
