A　preliminary　research　method　of　capturing　driving　motion　data　based　on　BVH　was　proposed.　The　format　of　BVH　files　was　analyzedand　the　meaning　of　the　data　in　the　BVH　files　was　introduced.　The　driver＇s　coordinate　systemin　a　state　of　keeping　driving　was　established　by　using　the　skeleton　information　in　BVH.　The　forward　kinematics　method　was　used　to　compute　the　motion　capture　data.　With　the　analysis　and　processing　of　motion　capture　data,　the　complex　motion　data　istransformed　intospecific　space　absolute　coordinate.　Finally,　the　driving　motion　can　be　described　quantitatively.　This　study　can　help　to　understand　the　physical　parameter　of　driving　motion　and　driver　behavior.
