Abstract: The article deals with the problem of determining the rational number of gears of mechatronic transmission of a truck. A review of the designs of existing mechatronic transmissions of leading automobile manufacturers with emphasis on analyzing the number of gears used in them. A methodology for determining the rational number of gears is developed on the basis of simulation modeling of truck movement by driving cycles synthesized on the basis of statistical data on truck movement on the territory of the Russian Federation. The synthesized driving cycle and the simulation model of truck movement designed to determine the loads on the electromechanical transmission when driving on this cycle are considered. Based on the results of the simulation modeling of truck motion with different number of gears in the mechatronic transmission, conclusions are drawn about the impact of multispeed transmissions on the energy efficiency of electric trucks. Conclusions about the required number of gears for mechatronic transmissions of trucks when driving on the roads of the Russian Federation are formulated.
