In order to prevent traffic accidents caused by driver carelessness and reduce damage, many countries are enacting mandatory installation of advanced safety assistant system such as LDSW and AEBS. Advanced safety assistant systems support steering and braking functions related to the driving of vehicles, so vehicle inspection technology is required to ensure safety during the driving life cycle. Inspection methods using diagnostic equipment have limitations that they cannot directly check whether the device is operating normally. We intend to prepare inspection techniques by verifying the operation of advanced safety assistant systems. Research has been conducted on the conditions for activation and operation of advanced safety devices, and test bed are intended to be developed by applying simulation techniques to create these conditions.

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.

Advanced device-equipped Vehicles are actively developed and legislation is underway around the world. As a result, Automobile manufacturers and others aim to continue research on high-tech devices and develop high-performance devices. These state-of-the-art vehicles are the most basic devices of autonomous vehicles. The automobile industry is progressing very quickly, but the number of malfunctions in high-tech devices is also increasing. In particular, in the case of Autonomous Emergency Braking(AEB), it is essential to lead to an Accident when a malfunction occurs. Typical high-tech devices include camera sensors and radar sensors. Both sensors are connected and operated, but radar sensors are mainly longitudinal and camera sensors are mainly lateral. Accordingly, this study analyzes AEB devices that can cause accidents when malfunctioning, it deliberately malfunctions the highly relevant radar sensor to determine to what extent the radar sensor’s performance persists. We want to analyze the risk of malfunction and the limitations of radar sensors through comparative analysis with existing automobile manufacturing standards and CAN data.

Korea regulates the emissions of new-vehicles and used-vehicles through the clean air conservation act. Used-vehicles are subject to period technical inspection and comprehensive technical inspection. It is inspection method is divided into vehicle registration dates. And inspection methods and standards are different. Period technical inspection apply to the snap-acceleration mode. Comprehensive technical inspection apply to KD-147 mode, Lug-down3 mode and snap-acceleration mode. Snap-acceleration mode is the mode in which the engine reaches its maximum speed in idling and then returns the idling. The time is less than four seconds. Although rapid acceleration is made within 4 seconds, emissions of exhaust gas an error rate of up to 40 percent. This study compared the level of exhaust emissions according th the time of reaching engine RPM. The vehicle used in the experiment is a diesel vehicle with no DPF installed. As a result, the shorter the time to reach the target engine RPM, the higher the emission level of smoke. By utilizing the research results, the error rate of the smoke test results of the used-vehicles can be minimized, and it will be used the develop methods and inspection modes for nitrogen oxides.
