Abstract

In this paper by using the example of combined braking control of passenger vehicle of the segment C the estimation of influence of tribological characteristics of friction pairs of braking mechanisms to the braking process is performed. The obtained results enable to make a conclusion that at “cold” and “after cooling” braking mechanisms of the vehicle values of mathematical expectation of friction coefficient and dispersion of its values are approximately equal. The performed calculation indicates that when the friction coefficient changes by 8–20% the change of braking moment by 20–30% takes place. Thus, the difference between the largest and the smallest braking moments may be 50%, that may change the output characteristics and behavior of the investigated vehicle
