ITS기반 차량 전복 예측 및 방지 알고리즘 개발

This paper describes a ITS-based vehicle rollover prediction, warning, and prevention algorithm. Based on the information, such as vehicle position and digital geographic road information, obtained from ITS infrastructure, this system predicts a danger of rollover in advance. This system gives a warning to driver if the vehicle is going to rollover in advance, and controls the vehicle speed in order to prevent rollover if the driver does not effort in spite of the warning. A vehicle safety speeds for rollover prevention are proposed for each road curvature by using simulation analysis with various driving situations. A rollover index is employed to decide the rollover propensity in simulation analysis. Computer simulations are conducted to verify the proposed rollover prediction and prevention algorithm using Carsim, vehicle simulation software. The proposed system can offer drivers safe driving circumstance and be an effective way to prevent the vehicle from rollover accidents.
