고속도로 안전 주행을 위한 차량 능동 조향 제어 연구

초록

There are some reports saying that over the half of reasons of car accidents on the highways are due to dozing off at the wheel. To prevent those accidents, this paper suggests a way to control the steering wheel actively when unwilling lane departure of car occured. The activation condition of the control system is decided by turn signal and the information of the vehicle, such as location, velocity and etc.. By using those information of the vehicle, the control algorithm become activated and carried out to minimize the possibility of accidents. As rapid steering control can cause other car accidents, the controller must control the car with proper steering speed for the safety. The simulaton was carried out to validate the algorithm first and the algorithm was implemented on the test system. Futher study will be carried out to improve the algorithm and adapt to actual vehicles.
