Motion　system　is　the　main　part　of　the　vehicle　driving　simulator　which　is　presented　in　this　paper.　The　control　algorithm　of　6-DOF　platform,　called　washout　algorithm,　which　is　the　important　part　of　the　motion　system　is　researched　in　this　paper.　Although　The　traditional　classic　washout　algorithm　has　the　advantages　of　simple　and　fast,　but　can　not　fully　simulate　the　full　working　condition　of　vehicle　driving.　Therefore,　the　adaptive　washout　algorithm　is　analyzed　and　simulated.　Through　the　human　evaluation　model,　simulation　results　are　evaluated　and　compared.　Simulation　results　show　that　the　algorithm　is　better　than　the　classical　algorithm　in　the　accuracy　and　stability　of　its　output,　which　can　simulate　the　full　working　condition　of　vehicle　sports,　and　it　improves　the　simulator＇s　better　fidelity.　©　2011　IEEE.
