Abstract

This paper presents a design of electrified hydraulic control system for a parallel type hybrid electric vehicle (HEV) with continuously variable transmission (CVT). Considering the hybrid characteristics and CVT feature which requires high line pressure to supply the demanded clamping force, three electrified hydraulic system: (1) 1-MOP+1-EOP, (2) 2-EOP and (3) 1-EOP were proposed and the energy consumption was evaluated. The EOP displacement was designed considering the demanded flow rate and pump efficiency. To investigate the amount of flow, pressure and energy consumption of the electrified hydraulic control system, an AMESim-MATLAB/Simulink co-simulator was developed for the target HEV, which consists of the vehicle powertrain and hydraulic system model. From the simulation results, it was found that 2-EOP system shows the smallest energy consumption while satisfying the required control, lubrication and leakage flow.

采用电动油泵的并联式无级变速混合动力汽车能耗分析

介绍了一种无级变速并联混合动力汽车(HEV)电动液压控制系统的设计。考虑到混合动力特性和无级变速器需要高管路压力提供所需夹紧力的特点，提出了(1)1- mop +1- eop、(2)2- eop和(3)1- eop三种电动液压系统，并对其能耗进行了评价。EOP排量的设计考虑了所需的流量和泵效率。为了研究电动液压控制系统的流量、压力和能耗，针对目标HEV开发了AMESim-MATLAB/Simulink联合仿真器，该仿真器由整车动力总成和液压系统模型组成。仿真结果表明，在满足控制、润滑和泄漏流量要求的情况下，2-EOP系统的能耗最小。
