This paper presents the results of a mathematical modeling study on the influence of a hydrostatic regenerative braking system on vehicle motion and braking performance. The model accounts for resistance forces acting during vehicle movement, including wheel rotational resistance, aerodynamic drag, gravitational components, and forces generated by the hydraulic system. Using models developed in the MATLAB-Simulink environment, the vehicle’s acceleration, velocity, position, and pressure variations within the hydraulic system, as well as their time dependencies, were analyzed graphically. Additionally, the movement, torque, and flow of the hydraulic pump/motor components were evaluated to assess overall system efficiency. The study demonstrates that a hydrostatic braking system enables balanced control of vehicle motion, effective energy recovery, and reduction of operational costs. This approach is significant from the perspectives of environmental sustainability and fuel consumption reduction.
