The impact of roads unevenness, i.e. presence of upward and downward motion zones in the road on auto transport fuel consumption is studied. The task of calculation of optimum interrelation of motion speed and acceleration at the uneven roads in sense of reaching of minimum consumed fuel and minimum emissions on environment is formulated and solved. In the study, an analysis of known works on the topic of research was carried out, which showed that the unevenness of the road, i.e. the presence of descents and ascents on the route is one of the main reasons that led to an increase in fuel consumption by vehicles on the route, while the problem of calculating the optimal functional relationship between the speed and acceleration has not yet been solved. Formulated and solved the problem of finding the optimal relationship between the speed and acceleration of vehicles in terms of achieving the minimum fuel consumption on an uneven track. Practical recommendations have been developed for the implementation of the proposed optimal driving regime on uneven terrain containing descents and ascents.
