An Experimental Study of Test-bed of Dynamic Process-oriented HEV Control Method
-
摘要: HEV多能源动力总成控制过程中,处理HEV动态特性的提高和系统动力源能量消耗增加之间的矛盾是混合动力系统过程控制中的难题之一。提出面向动态过程的HEV多能源动力系统控制方法(DPCM方法)。建立以DPCM方法为控制理论基础的实验系统,在车辆传动试验台实验中,通过对不同加减速规律下所需输入动力的分析比较,验证了DPCM方法中的HEV设定车速分阶离散化控制方法对有效降低HEV所需的总输入力矩、降低能量消耗等方面起到了积极作用。实验证明,DPCM方法既能保证HEV动态特性良好,又能有效控制HEV动力源能量消耗,使HEV节能目标得以真正实现。

Abstract: The control method for the HEV propulsion system based on the dynamic process was proposed (the DPCM method). The experimental system has been built on the base of the DPCM method. The controlling effect of the DPCM method was validated by the experimental system. Through the vehicle-transmission-test-bed experiment, the driving power under different accelerated rules were compared, which helps to validate that the method advanced in this disserta-tion succeeds in optimizing the dynamic characteristics of the HEV and restricting the energy consumption. The experi-ment proves that the DPCM method can help the optimized target of the control strategy to be implemented. -
