상용트럭 AEBS용 레이더 및 비전센서 평가기술 개발

HKMC, KATECH, SNU and KATRI has been developing the AEBS for trucks and buses from 2010. The role of KATECH is to develop driving simulator connected HILS for investigating AEBS control parameters, to develop the T-car based test-bed and test method for evaluating the sensor systems used for HKMC AEBS. These test results are used for designing the AEBS. The AEBS uses both 77GHz microwave radar developed for ACC and FVCMS and vision sensor together. The AEBS is basically developed for very heavy trucks such as 25 ton truck named TRAGO. KATECH used a SUV vehicle named SantaFe as a test platform. A mount is designed to meet the installation height of the sensors, and sensor signal was taken from the mounted sensors. Originally, two types of radar was tested, but this paper contains the result of only on type. After installation of sensors, the sensors are calibrated according to the sensor installation directions. The data under consideration was relative distance between subject vehicle and target vehicle, relative speed, detecting angles, detecting range, and etc. The test results show the measuring error of radar and vision sensor for different distances, measuring angles, relative speed, and etc. The test was processed for stationary conditions and driving conditions with 40 km/h and 60 km/h.
