Research on Heat Transfer Regulation of Power-Split Hybrid Electric Vehicle under Silent Watch Operation


Article Preview

Silent watch operation is a typical driving condition of power-split hybrid electric vehicle (PSHEV) which has advantages of both series and parallel HEVs. Because of the complicated structure and operations of PSHEV, an advanced thermal management system with effective control strategy is needed urgently. Properly-adopted heat transfer regulations under different vehicle driving conditions are the basis of TMS control strategy establishment. In this study, we begin this work from the typical vehicle operation-silent watch operation. Then, the heat transfer regulation of PSHEV under silent watch operation is researched and analyzed with the present advanced TMS. The results can provide theory and data bases for the future research of TMS control strategy for PSHEV.
