This　paper　introduces　the　implementation　process　of　intelligent　vehicle　path　planning,　including　the　establishment　of　environmental　models,　path　search　algorithm,　as　well　as　the　visualization　of　digital　map.　Firstly,　the　article　introduces　the　path　planning　and　several　algorithms;　secondly,　the　A　*　algorithm　is　described,　as　well　as　the　representation　of　environment　model;　thirdly,　the　article　introduces　the　MapX　component　and　gives　the　implementation　steps　of　visualization　based　on　MapX;　finally,　the　experiment　results　are　presented,　the　experimental　results　show　that　the　A　*　algorithm　could　easily　find　the　optimal　path,　reduce　the　searching　space　of　the　algorithm　and　make　the　planning　result　more　reasonable.　Besides,　the　digital　map　based　on　MapX　could　perfectly　display　vehicle　location　and　the　planned　route　in　real　time.
