Abstract
Based on the Grey system theory, a new analytic method for the braking force distribution of motor vehicle is presented. The braking force distribution between front and rear wheels of motor vehicle is studied by means of the incidence analysis of grey system theory. Since the incidence size represents the difference between actual braking force distribution curve â and ideal I curve of motor vehicle, so the optimal braking force distribution curve âcan be hereupon found. The analysis of actual examples shows that the greater the incidence size, the closer are the actual braking force distribution curve and the ideal one.
