실차 데이터를 이용한 차륜과 노면간의 마찰계수 예측에 관한 연구

In this study, the possibilities of estimation of friction coefficient between tire and road surface using running car data are checked. To get necessary data, such as tire and car velocities and braking force, a test car is driven with certain magnitude of decelerations from pre-set initial velocities to stop. The data are used to estimate friction coefficient with properly chosen parameters, e.g., driving stiffness, pressure distribution functions, etc. Experimental results show that running car data can be used with properly chosen parameters to estimate friction coefficient.
