Simulation system and method for plug-in hybrid electric bus

Abstract

The invention discloses a simulation system and method for a plug-in hybrid electric bus. The method comprises the steps that a first user layer leads received parameters in a functional layer used for parameter selection, and a second user layer leads received parameters in a functional layer used for performance analysis; the functional layer used for the parameter selection determines the feasible value range of the component parameters to be selected after receiving the parameters received by the first user layer and then selects optimization modes according to whether selective parameter combinations can be determined or not; the functional layer used for the performance analysis receives the parameters received by the second user layer and leads the parameters in a core layer; the functional layers call a finished bus simulation model of the core layer and a control strategy for simulation after determining the optimization modes and transmit the final results to the corresponding user layers for display. According to the simulation system and method for the plug-in hybrid electric bus, the parameter selection and optimization of the key components of a power assembly and the analysis and prediction of the performance of the finished bus are achieved.

Description

technical field [0001] The invention relates to the field of complete vehicle simulation of new energy vehicles, in particular to a simulation system and method for a plug-in hybrid electric bus. Background technique [0002] In recent years, the price of the world oil market has fluctuated violently. Governments of various countries have adjusted their energy strategies one after another. In addition, vehicle exhaust emissions have caused serious urban air pollution. With the rapid development of the economy, the country has paid more and more attention to energy conservation and environmental protection. There is an upsurge of research and development of electric vehicles at home and abroad. [0003] The plug-in hybrid electric bus has the characteristics of both hybrid electric buses and pure electric buses. It also has the working mode of motor independent drive like pure electric buses, which can fully meet the requirements of low-speed, high-torque and high-speed drivi...

Problems solved by technology

[0004] At present, for the simulation system of the whole vehicle, there are more common technologies, such as AVL CRUISE, etc. Most of the simulation software in this part are basic software, which can be used for all vehicles, and the focus is on small cars, but its pertinence is poor. The simulation content is limited, and it is difficult to integrate and modify the control strategy, especially the system structure and control method of the plug-in hybrid electric bus are relatively complicated at present, and the control strategy is in the stage of research and improvement internationally, so the general It is difficult to build a complete targeted system with software, so it is necessary to develop a plug-in hybrid bus simulation system
