The paper presents methods for mathematical planning of an experimental study on the resistance against vehicle moving as a multi-effect system. The factors influencing on the process of rolling with vehicle moving have been analyzed.

Analysis of factors influencing the process rolling when the vehicle is in motion on a hard surface makes it possible to analyze the main ways to influence it.

Generally accepted methodology for testing the coefficient of rolling resistance is

single-factor experiment. From previous research show that, the coefficient of rolling resistance is influence from many factors.

Unlike single-factor planning of experiment for multifactorial study

There are ways to assess the significance and impact of individual factors in the development of phenomenon in time of experiment. This makes it possible without undue loss of time to

obtain accurate results.
