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 car 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.
