Abstract: An integrated control technology of vehicle chassis based on multi-agent system (MAS) is brought forward, which aims at overcoming the shortage of coordinated control on vehicle chassis subsystems between semi-active suspension (SAS) and electric power steering (EPS). A sub-multi-agent system is built for an integrated control between SAS agent and EPS agent. And a multi-agent integrated controller based on embedded operating system is developed, and vehicle tests are made respectively on self-adapting fuzzy integrated control and MAS integrated control, which intents to evaluate the performance of the integrated system of SAS and EPS. It can be seen that the coordination solving mechanism of MAS integrated system resolves the match problem of SAS and EPS and their coordination control effectively.

Keywords: vehicle suspension; semi-active suspension; SAS; electric power steering; EPS; integrated control; multi-agent systems; MAS; agent-based systems; vehicle control.
