Embodiment

[0062] An XML-based vehicle performance simulation data architecture approach includes the following specific embodiments:

[0063] A1, according to the user's selection, obtain the selected simulation subsystem name, determine if the system has existed the history simulation subsystem running file, if there is, pass the data information through the XML file, execute the model layout configuration file, perform the simulation run file; Otherwise, perform step two.

[0064] A2, according to the system selected in step A1, pass the selection information based on the name of the selected name, obtain the base data file (M file, Simulink file, mat file).

[0065] A3, according to the base data file acquired in step A2, further acquire the parameter profile of the subsystem, and determine if the acquired data file is complete, if it is not complete, then Re-acquire the subsystem parameter configuration file, until the obtained parameter configuration file is fully matched with the sele...

Abstract

The invention provides a vehicle performance simulation data architecture method based on XML. The vehicle performance simulation data architecture method comprises the following steps: S1, selectingsimulation subsystem names; s2, acquiring a basic data file; s3, executing the model layout configuration file, and performing automatic modeling; s4, acquiring a parameter configuration file at the same time, and judging whether parameter configuration is complete or not; s5, displaying the XML parameters on a UI interaction interface, and selecting whether to modify system self-defined parameters or not; s6, marking the running sequence of the subsystem parameter configuration files, and executing the preprocessing process of the parameters according to the execution sequence; s7, forming acomplete vehicle performance simulation model by the parameters generated by parameter preprocessing and the automatically generated model file; and S8, executing the simulation running file. According to the vehicle performance simulation data architecture method based on the XML, a set of digital data architecture of a whole vehicle is established, and refined modeling is performed on parameters, models and controllers of components, so that redevelopment of the models and the controllers is facilitated, and the software expansibility is enhanced.

Description

Technical field [0001] The present invention belongs to the technical field of simulation data architecture design and development, in particular, to an XML-based vehicle performance simulation data architecture method. Background technique [0002] At present, in the process of automotive design research and development, computer simulation technology plays a pivotal role. With the intensification of market competition, the update of new products is getting faster and faster, using simulation technology plays a significant impact in solving problems in the development process, and enhancing corporate benefits, enhancing core competitiveness Provide technical guarantees. As a simple, flexible markup language, XML provides a unified approach to describe and exchange structured data independent of the application, with strong data storage and analysis capabilities, cross-platform, cross-program applications. Combined with MATLAB / Simulink has a powerful visualization, establish a ...
