Abstract
This article presents the results of analysis of power distribution in an electric vehicle independent all-wheel drive. The utilized method of velocity distribution takes into account the change in the motion resistance occurring on particular wheel. Moreover, the method of determining the change of vertical loads on traction wheels is also described. Theoretical considerations were verified on a dedicated laboratory stand that allows to perform real time simulation for analysed powertrain structure. The results of two different scenarios of vehicle driving in curvilinear motion are presented.

In the last decade, a significant increase in the popularity of electric road vehicles has been observed
The article presents the method of speed distribution for electric vehicle independent all-wheel drive
The change in motion resistance on each wheel was taken into account depending on the instantaneous values of the parameters determining the change in vertical loads on each wheel
Summary
A significant increase in the popularity of electric road vehicles has been observed. The intensification of scientific research devoted to this subject is an indispensable process Most of these studies raise issues related to energy analysis of the propulsion system [1, 2], component modelling [3, 4] and the possibility to reduce energy consumption [5, 6]. The aspects of motion kinematics of a four-wheeled electric vehicle equipped with independent drive of all wheels will be elaborated. These considerations constitute a continuation and extension of the studies presented in [9,10,11]. While the arrows indicate the possible direction of the energy flow depending on the EM operating mode (acceleration/braking)
