CarMaker를 활용한 운전자 보조시스템의 가상 환경 구축

Collision Avoidance System(CAS) in Advanced Driver Assistance System(ADAS) is an Active Safety System 7 helps the driver to avoid or mitigate rear-end collisions by using forward looking sensors(e.x. Radar, Camera etc.) and brake/steering assist systems(e.x. ESP, EPS etc.). This paper deals with Collision Avoidance System algorithm which is activated when the traffic situation is in very danger. Using driving Situation Assessment algorithm which is composed of many parameters, we classified how dangerous the current driving situation is. If the driver does not react in emergency cases, the Collision Avoidance System generates assisting braking pressure or steering torque automatically in order to avoid a collision. Finally, we present a basic control strategy for the Collision Avoidance System. All simulation environments is constructed by vehicle dynamics simulation program so called IPG CarMaker, and we show convenience and suitability of simulation and evaluation method by using IPG CarMaker in order to analyze and optimize the performance of ADAS and CAS.
