This　paper　discusses　the　composition　and　function　of　an　advanced　controller　system　of　Car　Black　Box.　The　system　can　not　only　record　the　main　driving　data　of　the　cat　comprehensively　and　accurately　in　real-time,　but　also　reconstruct　the　accident　with　data　process　software,　which　can　help　people　analyze　the　accident　rapidly　and　legitimately　after　a　collision.　A　review　of　recent　researches　on　Car　Black　Box　is　first　presented　in　this　paper.　The　author　then　analyzes　the　main　problems　and　development　direction　of　Car　Black　Box　and　put　forward　the　necessity　of　developing　Car　Black　Box　with　high　performance.　The　author　also　proposes　an　integrated　design　solution　for　Car　Black　Box.　The　design　selects　the　Samsung＇s　S3C2410,　which　includes　CAN　controller,　pulse　counter　module,　A/D　convert　module　and　GPIO　interface,　audio-out,　RS232　interface　and　USB　port.　The　Car　Black　Box　can　receive　real-time　data　including　driving　speed,　rev,　light,　car　door,　tire　pressure,　brake,　lay-up　and　life　belt,　and　also　process　the　data　and　store　it　in　RAM.　Based　on　the　experiment,　it　is　proved　that　the　designed　hardware　circuit　can　work　accurately　and　reliably.　©　2010　IEEE.
