PURPOSE: A car road surface detection system can obtain the information on obstacles in front of a vehicle and on road surface, prevent vehicle collisions by providing the information to drivers before the vehicle passes, improve ride comfort by controlling shock absorption with collision prediction, and control the safe position of the vehicle. CONSTITUTION: A car road surface detection system comprises: an IR laser part (110) radiating a laser light or an infrared slit light; a camera part (120) absorbing the laser light or the infrared slit light radiated by the IR laser part (110), to convert them into laser data for obtaining information on obstacles in front of a vehicle and on road surface status; and a control unit (140) controlling the operation of the IR laser part. The control unit comprises a laser data processing unit (150) sensing the amount of change of the laser data to produce information on obstacles in front of a vehicle and on road surface status.
