Simulation models of a hybrid vehicle were developed in the Matlab/Simulink environment to evaluate changes in normal and longitudinal wheel reactions of the vehicle’s axles under various driving modes. The developed hybrid vehicle model features a series-parallel drive of the driving wheels powered by asynchronous and synchronous electric motors as well as an internal combustion engine (ICE). The model includes subsystems representing vehicle components, a driver behavior simulator for controlling driving modes, and a hybrid vehicle control system. An analysis of changes in longitudinal and vertical wheel reactions during straight-line motion under specified modes—acceleration and regenerative braking—is presented. The obtained results correspond to practical values for the selected vehicle class. The analysis of the nature of reaction changes at the wheels enables the formulation of recommendations for reducing dynamic loads and inefficient energy consumption from the employed power sources.
