Recently, there has been increasing interest about vehicle active safety systems to prevent accidents which are caused by adverse weather conditions or inattention of drivers. Especially, ACC (Adaptive Cruise Control) systems using radar sensors are the most widespread.[1,2,3]
But it has not been clearly suggested how to test the automotive radar which is applied on the vehicle. In addition, it can be tested on limited place like a laboratory for short distance and it cannot be tested for long distance over 50m.
Performance evaluation method is verified by comparing the difference of distances between base vehicle (which the radar sensor is mounted) and target vehicle measured by the precise positioning technology and the radar sensor. It is also possible to test ACC system on a driving road over 50m.
In this paper, the precise positioning technology using the VRS and INS is proposed and verified. As a result, the test environment is achieved on driving test ground located on the Korea Automotive Technology Institute (KATECH), and performance of the radar sensor is tested for the base and target vehicles equipped with the test equipment.
This test method is applicable to Advanced Driver Assist System (ADAS) related to the positioning and distance information. It is also possible to test on the driving road, to get some of car performance ratings such as ACC and Forward Collision Warning System (FCWS).[3∼4]
