Benefits of technology

This technology allows two separate simulations on one computer program to work together better than previous methods without sacrificing their benefits or requiring extra effort. By doing this with both programs at once it provides greater flexibility during testing scenarios that are difficult if only done separately by each other's developers.

Problems solved by technology

The technical problem addressed by this patented technology relates to developing an effective method for analyzing multiaxially driven slip wagon vehicles' behavior during different driving situations while maintaining their stability under severe environmental factors like rainwater snowfall.

Abstract

The present invention provides a multi-wheel individual drive slip frequency steering vehicle united simulation method and system. The method comprises the steps of: creating a whole vehicle rigid multi-body dynamical model at first software, determining input information and output information of the whole vehicle rigid multi-body dynamical model, and outputting a whole vehicle model submodule, wherein the whole vehicle model submodule comprises the whole vehicle rigid multi-body dynamical model, the input information and the output information; creating a driver model at second software, wherein the driver model is configured to output driving data according to input expected data and feedback data; creating a whole vehicle controller at the second software, wherein the whole vehicle controller is configured to receive the driving data, and generate torque information; creating a steering simulation model at the second software, and leading the whole vehicle model submodule, the driver model and the whole vehicle controller into the steering simulation model; and designing a working condition in the steering simulation model to perform simulation analysis of the work condition and obtain a simulation result. The multi-wheel individual drive slip frequency steering vehicle united simulation method and system can perform closed-loop simulation analysis of different work conditions and can improve the accuracy.
