【摘要】：針對在控制器局域網(wǎng)(CAN)總線中存在低優(yōu)先級信息會因為高優(yōu)先級信息頻繁占用總線而出現(xiàn)的死鎖問題,在車輛控制系統(tǒng)中引入柔性時間觸發(fā)機制組建柔性事件觸發(fā)控制器局域網(wǎng)(FTT-CAN),針對周期信息和隨機信息,分別在FTT-CAN的同步相和異步相中采用最早截止期優(yōu)先(EDF)調(diào)度和動態(tài)提升優(yōu)先級(DPP)調(diào)度,介紹了FTT-CAN觸發(fā)原理,提出基于EDF和DPP的動態(tài)調(diào)度算法,將該調(diào)度算法應(yīng)用于典型電動汽車控制系統(tǒng)模型的調(diào)度,驗證了該調(diào)度算法的優(yōu)越性。
[Abstract]:In view of the deadlock problem of low priority information in the (CAN) bus of the controller LAN because the high priority information frequently occupies the bus, Flexible time trigger mechanism is introduced into vehicle control system to construct flexible event trigger controller local area network (FTT-CAN), which aims at period information and random information. In the synchronous phase and asynchronous phase of FTT-CAN, the earliest deadline priority (EDF) scheduling and dynamic lifting priority (DPP) scheduling are adopted, respectively. The principle of FTT-CAN trigger is introduced, and the dynamic scheduling algorithm based on EDF and DPP is proposed. The algorithm is applied to the scheduling of typical electric vehicle control system model, and the superiority of the algorithm is verified.
