Abstract

The invention relates to a method for distinguishing working conditions and managing and controlling the energy of a plug-in hybrid electric vehicle. The method disclosed by the invention mainly comprises two parts of a method for distinguishing the working condition and a method for managing and controlling the energy. For the working condition distinguishing part, a support vector machine (SVM) model is adopted for training and studying the characteristic parameters of the working conditions so as to distinguish real-time working conditions; for the energy managing and controlling part, a fuzzy rule is formulated. Through the method for distinguishing the working conditions and managing and controlling the energy, and on the premise of ensuring power performance, the fuel economy of the vehicle can be markedly improved, and the energy conservation and emission reduction can be realized.

Description

technical field [0001] The invention relates to a method for working condition identification and energy management and control of a plug-in hybrid electric vehicle, which is applied to the hybrid electric vehicle. Background technique [0002] The control goal of hybrid electric vehicles is to make the engine run along the best fuel economy curve, and at the same time make the electric motor work at high efficiency as much as possible, so as to realize the efficient use of energy and achieve the goal of energy saving and emission reduction. The Toyota Prius hybrid vehicle can make the engine run along the best fuel economy curve, but because it uses a planetary gear power distribution mechanism, the mechanism is complex and requires high control accuracy, and its versatility is not strong. In 2007, P. Sharer et al. used PSAT software to establish Toyota Prius and Ford Focus car models. By introducing an operating condition multiplier to establish different operating conditi...
