| 面對(duì)能源和環(huán)境的巨大壓力,混合動(dòng)力汽車(hybrid electric vehicle,HEV)已成為汽車工業(yè)發(fā)展的重要方向�；旌蟿�(dòng)力電動(dòng)汽車與傳統(tǒng)汽車有很大不同,具有獨(dú)特而又復(fù)雜的能量及驅(qū)動(dòng)系統(tǒng),故對(duì)控制系統(tǒng)的要求更高和依賴性更強(qiáng)。該系統(tǒng)可以歸結(jié)為一類具有高度不確定性和強(qiáng)非線性的混雜切換動(dòng)態(tài)系統(tǒng),其優(yōu)化控制策略的優(yōu)劣直接影響車輛的經(jīng)濟(jì)性、可靠性、安全性和舒適性。然而混合動(dòng)力電動(dòng)汽車能量及驅(qū)動(dòng)系統(tǒng)的控制器設(shè)計(jì)卻面臨眾多挑戰(zhàn),現(xiàn)代控制理論和技術(shù)則是解決這一技術(shù)瓶頸的關(guān)鍵手段。本文從系統(tǒng)與控制科學(xué)的角度,深刻全面地綜述了HEV能量及驅(qū)動(dòng)系統(tǒng)的能量管理策略、車載動(dòng)力電池狀態(tài)估計(jì)、驅(qū)動(dòng)系統(tǒng)及其優(yōu)化控制等關(guān)鍵科學(xué)與技術(shù)問題及其研究進(jìn)展,最后指出了HEV能量及驅(qū)動(dòng)系統(tǒng)優(yōu)化控制技術(shù)和理論面臨的挑戰(zhàn)和發(fā)展趨勢(shì)。 |

| Faced with great pressure in energy and environment,the hybrid electric vehicle(HEV) has become an important development trend of the automobile industry.The HEV is remarkably different from traditional vehicles,and puts more requirements and dependencies on the control system,due to its unique and complicated energy and driving systems.Such a system can be formulated as a class of hybrid switching dynamic system with high uncertainty and strong nonlinearity,and the performance of optimization and control strategy is closely linked with the economy,reliability,safety and the comfort of the HEV.However,there are still many challenges in designing a controller for the energy and driving system of the HEV.Fortunately,modern control theory and technology provide key methods to overcome these technical bottlenecks in energy and driving system of the HEV.From the viewpoint of system and control science,this paper profoundly and comprehensively summarized some key scientific and technical issues and their development,such as the energy management strategy of the HEV energy and driving systems,the state estimation of the HEV traction battery,and the optimal control of the HEV driving system etc.Finally,the challenges and development tendency of the optimal control technologies and theories on the HEV energy and driving systems were also pointed out. |
