    摘要:

    設(shè)計(jì)了電磁功率分流混合動(dòng)力系統(tǒng),此系統(tǒng)采用雙轉(zhuǎn)子有刷電動(dòng)機(jī)對(duì)發(fā)動(dòng)機(jī)進(jìn)行功率分流調(diào)節(jié),可同時(shí)起到電磁離合器和無(wú)級(jí)變速箱的作用。在分析系統(tǒng)結(jié)構(gòu)、工作原理和確定整車(chē)控制模式的基礎(chǔ)上, 基于NEDC循環(huán)利用整車(chē)仿真模型對(duì)控制模式進(jìn)行了驗(yàn)證,并對(duì)整車(chē)動(dòng)力性和經(jīng)濟(jì)性進(jìn)行了分析。結(jié)果表明:針對(duì)電磁功率分流混合動(dòng)力系統(tǒng)所涉設(shè)計(jì)的傳動(dòng)控制模式在各種工況下工作正常;采用該控制模式的整車(chē)0~100 km/h加速時(shí)間為12 s,滿足最大爬坡度的指標(biāo),符合整車(chē)動(dòng)力性設(shè)計(jì)的要求;整車(chē)的綜合油耗為4.75 L/(100 km),與傳統(tǒng)車(chē)相比節(jié)油率達(dá)到41.3%。

    Abstract:

    A electromagnetic power-split (EMPS) hybrid electric vehicle was designed. This system with dual-rotor brush motor could be used to modulate the engine power flow, also can be used as electromagnetic clutch and CVT. The system configuration, working principle, the vehicle control mode and etc were analyzed. The control mode was tested under the NEDC based on the vehicle simulation platform. The dynamic and economic performances of the EMPS HEV were analyzed. The results noted that the designed vehicle control mode of the EMPS HEV worked properly under different cycles. The results also noted that the time from 0 km/h to 100 km/h was 12 s and climbing grade was bigger than 17°, these values were all satisfied with vehicle dynamic target. The average fuel consumption under the NEDC was 4.75 L/(100 km), the fuel can be saved was 41.3% compared with the related conventional vehicle. 
