KATECH(Korea Automotive Technology Institute) has just finished the fourth year development of KAAS system. This system is designed and developed as a test and development environment for highly advanced automotive electronic systems such as telematics. ASV(Advanced Safety Vehicle). ADAS(Advanced Driver Assistance System) and ITS (Intelligent Transportation System). To simulate such devices, the KAAS system is consisted of several major components including the nation's largest driving simulator system, driver monitoring and analysis systems, Real-Time HILS systems, a GPS simulator with RF antenna and a CDMA based wireless communication simulation system. With those components, the KAAS system will be able to test and analyze vehicle, driver, target device, and target software of the state of art technology. This paper contains the overall system design and integration process of the KAAS system. Currently installed systems are driver monitoring/perception analysis system and Real-Time HILS system, while GPS simulator and wireless communication system are still under development process. This paper also includes the test result of HILS system from a virtual driving.

KATECH(Korea Automotive Technology Institute) has been developing a driving simulator named KAAS(KATECH Advanced Automotive Simulator) which includes spherical screen with 360x35° FOV(Field of View), a full dome, a medium size full car cabin, a large scale 6DOF motion platform(7 ton payload; full dome screen and car cabin is mounted on the motion platform), scenario operating system and others. Among the driving simulator systems in Korea, KAAS is the largest one. As a result of three years of research, KAAS system is now in test operation. KAAS system will be used for developing advanced automotive electronics such as telematics, advanced safety devices, and driver assistance systems proving an accident-free test and development environment for Korean automotive manufactures. In order to satisfy the original purpose of the simulator, the KAAS system will be integrated with realtime HILS system, a in-vehicle network simulation system, wireless communication simulation systems, high speed signal analysis devices, a driver perception analysis system, and a GPS signal simulation system. This paper mainly discussed on the driving simulator part of KAAS system, and another paper presented in this conference covers the current development of rest part of KAAS system including HILS system. Because multi-year in-depth research was required for each component, the development of each component can be regarded as separate research topics. As a first step of simulator validation, the output signals from the vehicle dynamics (translational acceleration and angular rate in XBody, YBody and ZBody) are compared with the actual measurement of dome motion using a 6 axis gyroscope/accelerometer package. The result show the fair match of acceleration trends, but need more fine tuning of the motion platform control algorithm.

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.

In recent years, the roles of in-vehicle display systems have been significantly increased due to the increased demand of display information from car-IT fusion products such as multimedia, car navigation, ASV, telematics and many others. There is one key factor when designing the in-vehicle display that are to minimize the driver workload and to optimize the interface efficiency. In this research, the evaluation method for measuring the driver workload is investigated. The evaluation process includes, DOE, Secondary task (reaction time and correct rate) and bio-signal analyzing. One set of experiment with more than 18 persons have been conducted with several display designs while the driver is analyzed. Experiment results have been used to develop the design guideline to minimize the driver workload and to optimize the screen design.

The purpose of this research is to develop the evaluation technologies for ASV(Advanced Safety Vehicle) system. In the first year among three year research, KAAS (KATECH Advanced Automotive Simulator) system which is the largest DS (Driving Simulator) in Korea is utilized to evaluate AEBS (Automatic Emergency Braking System). This project is under the support of MLTM since the AEBS will soon be released in the Korean market. The research includes development of HILS system for AEBS ECU test, dynamics simulation, function test and usability test of AEBS HMI. Overall test environment is based on the integrated system of KAAS system, HILS, dynamics simulation tools and HMI devices.
