A vehicle dynamic matching and performance analysis method based on Visual Studio and Matlab hybrid programming

Abstract

The invention discloses a vehicle power matching and performance analysis method based on Visual Studio and Matlab hybrid programming. According to the software, a whole vehicle and each sub-model areconstructed by using an MATLAB programming language; An M file is compiled into a C language or a C + + language through Visual Studio2010 to be called, an independent application program separated from an MATLAB environment is generated, and the powerful data processing function and the image drawing function of the MATLAB are still reserved. By applying the hybrid programming method disclosed by the invention, parameters of each part of the whole automobile can be input into software; The whole automobile is simulated and calculated through a program, and no whole automobile object is needed. The dynamic property and the economical efficiency of the whole vehicle can be calculated only by inputting parameters into the parameter box corresponding to the software interface and pressing corresponding operation buttons, and a user does not need to master MATLAB language and automobile theory related professional knowledge. The method has the advantages that the software running speed ishigh, the method can run on a computer under the condition that MATLAB (Matrix Laboratory) and Visual Studio2010 software are not started, the operability is high, and a large amount of time and computer occupied space are saved.

Description

Technical field: [0001] The invention relates to the field of new energy vehicles, in particular to a vehicle power matching and performance analysis method based on Visual Studio and Matlab hybrid programming. Background technique: [0002] With the vigorous promotion of new energy vehicles in the country, many subsidy measures have been introduced accordingly. More and more car companies are transforming to produce new energy vehicles. It is necessary to reasonably design and match the parameters of their power systems, and to calculate and analyze their performance. , through secondary matching analysis and verification to achieve the purpose of optimization, so the demand for new energy vehicle performance simulation increases. Although the existing vehicle performance simulation software AVL-Cruise can use modular modeling methods to integrate the models and parameters of various components, it must be set and changed according to the existing rules and options of Cruis...
