Accurate measurement of the tire-to-road coefficient of friction is a necessary factor in the analysis of vehicle dynamics when sliding composes part of the motion. In the past, numerous methods have been used to measure the coefficient of friction but the results of these methods seldom agree or yield the requisite accuracy necessary for a detailed analysis of vehicle dynamics. Tire traction is a complex process which has many variables. The method of using a portable accelerometer and a microcomputerized data acquisition and storage device was chosen as the best way to measure the coefficient of friction because it permits a test procedure which closely approximates the event being analyzed. Therefore, leaving the least number of variables unaccounted for. (Author)
