摘要:

四輪獨立驅動(dòng)電動(dòng)汽車(chē)控制系統對通信確定性有更高的要求。基于汽車(chē)總線(xiàn)開(kāi)發(fā)V模式流程,從四輪獨立驅動(dòng)控制系統通信需求出發(fā),設計其FlexRay通信網(wǎng)絡(luò );采用Network Designer生成網(wǎng)絡(luò )數據庫,導入到CANoe.FlexRay軟件對網(wǎng)絡(luò )進(jìn)行了全仿真、半實(shí)物仿真,驗證了所設計的FlexRay通信網(wǎng)絡(luò )的協(xié)議參數的正確性,最后將該網(wǎng)絡(luò )用于樣車(chē)中;實(shí)驗結果表明,所設計的FlexRay通信網(wǎng)絡(luò )完全可用于四輪獨立驅動(dòng)電動(dòng)車(chē)控制系統,具有較高的可靠性、確定性及實(shí)時(shí)性,能夠滿(mǎn)足控制系統的通信需求。

Abstract:

Four-wheel independent drive electric vehicle control system have higher requirements on certainty of communication. The FlexRay communication network was designed based on the vehicle bus development V pattern process and the needs of four-wheel independent drive control system communication. The network database was created by using the Network Designer, then it was imported to CANoe.FlexRay for network simulation and hardware-in-the-loop simulation, so the designed network was verified. Finally, the network was used in a prototype vehicle. Experiments results show that the designed FlexRay communication network can be used in four-wheel independent drive control system, and it has higher reliability and certainty, and it can satisfy the communication requirements of the control system.
