Matlab-based vehicle performance simulation and calculation method for automobile

Abstract

The invention discloses a Matlab-based vehicle performance simulation and calculation method for an automobile. The method comprises a first step of program calculation, a second step of file configuration, a third step of curve display, a fourth step of data display, a fifth step of data saving and a sixth step of report generation. The method is used for calculating vehicle basic performance data of the automobile and provides a basic theoretical basis for vehicle performance analysis and simulation of the automobile. When the method is applied to a new energy automobile, vehicle parameters of the automobile can be calculated through a Matlab, parameters of all parts of the whole automobile are input into software, the vehicle performance of the automobile is simulated and calculated through a program, the vehicle performance of the automobile can be calculated just through a computer without the need for a real automobile, specific professional knowledge does not need to be grasped, and therefore a large amount of time is saved.

Description

technical field [0001] The invention relates to a method for simulating and calculating the performance of a complete automobile based on Matlab, and belongs to the technical field of automatic control. Background technique [0002] At present, with the continuous development of new energy vehicle technology, the demand for performance simulation calculation of new energy vehicles is getting higher and higher, and the traditional simulation software used in traditional vehicles in the past is no longer suitable for the use of current new energy vehicles. Not only the data calculated by the software is inaccurate and detailed, but also the simulation speed is slow, and the custom configuration program is cumbersome, which completely cannot meet the requirements for high efficiency, precision and diversification of simulation calculation needs. [0003] Since there are more and more different car models, the parameters or parts of each car model are slightly different, it is i...

AI Technical Summary

Problems solved by technology

Advisor uses Simulink for modeling, the simulation speed is slow, and a large number of parameters need to be modified when configuring the vehicle parameters. In addition, the software version is relatively old, and there will be many problems when running on the new platform. Its stability is poor and the calculation speed is very fast. Slow, can not be applied to the simulation and calculation of a large amount of data

Cruise can modularly configure the parameters of each component of the vehicle, but the configuration must be within the rules established by Cruise, and only existing options can be selected for modification. The calculation methods are all encapsulated in the software and cannot be changed. The method of viewing and modifying the calculation is less flexible, and it is not convenient to customize the parameters and calculation data of various models
