【摘要】：為了解決混合動力汽車的實時能量管理及優(yōu)化問題,在保證不過多簡化被控對象的基礎(chǔ)上得到最優(yōu)解,該文提出一種基于V2X(vehicle to vehicle,車車通信,以及vehicle to infrastructure,車與交通設(shè)施通信)的分層控制方法。設(shè)計了一種分層控制器,上層控制器基于交通信號燈正時(signal phase and timing,SPAT)得到目標(biāo)車速的初始值,并采用多島遺傳算法和非線性模型預(yù)測得到最優(yōu)目標(biāo)車速。下層控制器根據(jù)上層控制器的最優(yōu)目標(biāo)車速,采用自適應(yīng)等效燃油消耗最小原理(adaptive equivalent consumption minimization strategy,A-ECMS),得到發(fā)動機(jī)和電機(jī)的最優(yōu)輸出功率。該文對分層控制方法進(jìn)行了硬件在環(huán)仿真,仿真結(jié)果表明,該文提出的分層控制方法可以很好地實現(xiàn)混合動力汽車的實時能量管理,有效地避免混合動力汽車紅燈停車,實現(xiàn)良好的車速跟隨并減少百公里油耗。該研究可為解決混動力汽車實時能量管理及優(yōu)化提供參考。
[Abstract]:In order to solve the problem of real-time energy management and optimization of hybrid electric vehicles and to obtain the optimal solution on the basis of not simplifying the controlled object too much, this paper presents a vehicle communication based on V2X vehicle to vehicle. And the layered control method of vehicle to infrastructure. a layered controller is designed. The upper controller is based on the traffic signal signal phase and timing to get the initial value of the target speed. The multi-island genetic algorithm and nonlinear model are used to predict the optimal target speed, and the lower controller is based on the optimal target speed of the upper controller. Using the principle of adaptive equivalent fuel consumption minimum, the optimal output power of engine and motor is obtained by adaptive equivalent consumption minimization strategy A-ECMS. In this paper, the hardware in loop simulation of the layered control method is carried out, and the simulation results show that, The hierarchical control method proposed in this paper can effectively realize the real-time energy management of hybrid electric vehicles and effectively avoid the red light stop of hybrid electric vehicles. The research can provide a reference for solving the real-time energy management and optimization of hybrid vehicles.
