    摘要:

    針對(duì)某混聯(lián)式汽車(chē)布置形式,分析確定了車(chē)輛行駛模式、模式切換過(guò)渡算法、行星排運(yùn)動(dòng)學(xué)限制模型，提出了基于功率跟隨的整車(chē)控制策略。利用Cruise和Matlab軟件，在Udc-auto循環(huán)工況下進(jìn)行聯(lián)合仿真。仿真結(jié)果表明：模式切換穩(wěn)定，車(chē)速跟蹤效果好，在車(chē)輛中高速加速工況下，可以控制發(fā)動(dòng)機(jī)在最低燃油消耗線附近，控制策略和算法是可行的。同傳統(tǒng)車(chē)輛相比，混合動(dòng)力汽車(chē)控制策略可以實(shí)現(xiàn)在同一循環(huán)工況下節(jié)油

    Abstract:

    55.42％。This paper analyzed and confirmed the whole car modes of driving, modes conversion transient algorithm, planetary system kinematics limited model for a certain parallel-serial hybrid electric vehicle configuration, and proposed based-power-track control strategy. Combining Cruise with Matlab, we carried out the combination simulation under Udc-auto cycling run condition. The simulation result showed that mode conversions are stable, and tracking pre-defined car velocity effect is good. The engine can be controlled to work at the vicinity of its optimizing curve under accelerating condition of medium and high velocity of vehicle. The control strategy and algorithm are valid. Compared with conventional vehicle, HEV control strategy can realize that the decreasing ratio of fuel consumption reaches 55.42% under the same cycle run condition.
