Research on Energy-saving Technology of Electrohydraulic Control System of Electromechanical Coupling Transmission for Plug-in Hybrid Electric Vehicle

Abstract

Along with the development of society, the increasing maturity of science and technology, our country ushered in the new era: the new energy era, which creates a favorable environment for the development of the national new energy automobile industry. By the state to give new energy vehicles policy incentives and support, expand the development scale of new energy vehicles, new energy vehicles have become a major vehicle enterprises and research institutions to discuss the hot spot. At the present stage, the development of pure motor trams is very slow due to the inadequacy of various basic supporting facilities such as low-level battery technology and charging piles. Plug-in hybrid electric vehicle (Plug-in hybrid electric vehicle) is an eff ective technical measure for the transition from traditional fuel vehicle to electric vehicle. The power coupling of driving motor and engine can ensure the power performance of the whole vehicle, minimize the economic cost and solve the problems related to the driving range of electric vehicle. Taking plug-in hybrid electric vehicle as an example, this paper analyzes the energy-saving technology and measures of the electro-hydraulic control system of the electromechanical coupling transmission of plug-in hybrid electric vehicle.
