Virtual vehicle system development and its application for ABS design based on distributed network

摘要

In this paper, we explore a novel method for building a virtual vehicle system, integrating pure software simulation and Hardware In Loop (HIL) simulation, which is constructed based on a distributed network of Controller Area Network (CAN) and TCP/IP. Firstly, the dynamic vehicle model is developed in the platform of software simulation, used to design and verify the response of ABS control logic. Secondly, in the HIL simulation the model equations are converted to a stand-alone program of C++ on main computer and integrated with ABS controller, real vehicle devices and components, generate a real vehicle environment based on CAN bus to verify the control performance of ABS in real time. Database, graphic and data processing systems are integrated by cross-platform programming technology on assistant computer connected by ethernet. The analysis and validation of developed control logic for ABS can be performed successfully on this platform.
