For development Telematics devices and software, traditional development methods including unit function test, compatibility test and T-car test often show limitations. The state of art Telematics devices have various functions including navigation, wireless communication, self diagnostics, DMB, audio & video and even vehicle control implying that the interactions among three major factors of automotive electronics - the vehicle, the device and the driver - need to be considered together whenever possible. This paper shows the virtual reality based test environment with KAAS(Katech Advanced Automotive Simulator). The two characteristics of the test systems are the CAN(Controller Area Network) protocol providing the real-time vehicle status and the real-time GPS signal indicating the current position of the vehicle. Therefore, the Telematics devices can be simulated in the virtual environment as if the devices are installed in a vehicle while the vehicle is driving simulator. The GPS simulator receives the vehicle status data such as vehicle position in the 3D virtual space in real time, computes the location of the GPS satellites above the vehicle, and sends the GPS RF signal of each satellite through the RF antenna mounted on the KAAS.

Recently, most automakers have been working on the development of advanced driver assistance systems with an emphasis on driver safety. Conventional BSD is a blind zone warning system, and most of them use radar equipment for obstacle detection. However, BSD systems using radar equipment are still difficult to popularize in terms of price. Therefore, there is a need to reduce costs by developing a multi-function using a popularized driver-assisted system sensor. In this paper, we propose an ultrasonic BSD warning system which has a blind zone warning function by using ultrasonic sensor for parking assist system.

Recently, as the level of autonomous driving increases, research and development on advanced driver assistance systems for the safety of drivers and passengers are actively underway. Existing BSD(Blind Spot Detection) systems based on ultrasonic or radar sensors have the problem of not being able to detect blind spots on the side of the vehicle because of the FOV(Filed of View) and mounting position of sensors, which is the recognition range of the sensor, is limited to the rear side of the vehicle. Therefore In this paper we proposed a SCA(Side Collision Avoidance) system using a LiDAR sensor. The performance of the proposed SCA system is evaluated in the simulation environment based on virtual reality.

Vibration of real vehicle originates an engine drive and form of road surface. It begins a fatigue accumulation of vehicle driver, with technology for restraint to vibration of vehicle is going to research and application. The vehicle seat vibrator is a simulator for vibration of real vehicle reappears. Vehicle vibration generated of virtual experiment a driver feel in vibration area. The oil pressure type vehicle seat vibrator of preexistence is limiting a vibration test plan of small scale for make because of high cost; with vehicle seat vibrator using single electric actuator develops. It study analyses systems limit and dynamics of vehicle seat vibrator. And control algorithms apply electric actuator for vibration test.
