To　realize　intelligent　integrated　of　vehicle　chassis　system,　multi-agent　theory　applied　in　cooperative　control　of　suspension　and　steering　subsystems.　This　paper　built　out　suspension　agent,　steering　agent,　cooperation　agent,　and　described　their　structures　and　attributes.　Put　up　chassis　cooperative　control　framework　according　cooperative　processes　of　multi-agent.　Query　simulation　of　multi-agent　was　carried　out　based　on　agent　development　platform　software　Aglets.　Results　show　that　cooperation　model　of　multi-agent　system　is　effective　on　coordinated　control　suspension　and　steering　subsystems.　©　2010　IEEE.
