In order to prevent automobile accidents internationally, advanced safety devices are actively being developed. Among them, Auto Emergency Brake (AEB) function and Forward Collision Warning (FCW), which are used to prevent or reduce frontal collision, have been studied for a long time, and are being researched by various manufacturers to develop better performance. In fact, in the case of large vehicles, it is mandatory for AEB to be installed in Korea. Accordingly, a variety of Vehicles equipped with AEB and FCW are coming out, and inspection of these mounting devices is a necessary system in the future. This study confirms how AEB and FCW are currently assessed in regulation and the New Car Assesment Program (NCAP), This is a basic study of the matters to be considered in preparing AEB and FCW inspection standard by checking the performance of vehicles equipped with forward collision protection and identifying the vehicle's sensitivity, range and speed of radar sensors, and target vehicles based on CAN communication data.
