| Abstract: | In this paper,a new method is set up to get the relation slip between coasting resistance and speed of automo biles,using the data of coasting test.This is based on the motion differential equation of coasting resistance calculation model.Then the paper calculates the numerical value of rolling resistance,air resistance and transmission resistance in process of coasting of the passenger cars.The changing rules and the characteristics of the transmission resistance are also analyzed in this paper. |
