Abstract: The aim of this work involving the charging process of hydro-pneumatic accumulators in the hydrostatic power transmission system is to propose ||optimal|| operating parameters of the control system, which will allow low petrol consumption, low emission of toxic fumes and verification of the proposed model. As a tool for the simulation work, a simulation application from the Simulink library for a Matlab environment was used. As a result of the research, characteristics of the process quantities, which confirm correctness of the proposed operating parameters of the control system were obtained. In addition, the quantitative and qualitative identification of the presented model was conducted.

Keywords: energy recuperation; engine control; hydrobus; hydrostatic transmission; accumulator charging; hydropneumatic accumulators; petrol consumption; low emission; toxic fumes; simulation; exhaust emissions; fuel comsumption; hydrostatic pump capacity; power transmission.
