Study of the autonomous mechatronic module of the car control system

Abstract

The aim of this work is to develop a design methodology for an autonomous electro hydraulic mechatronic module (AMM) for the steering system of multi-axle heavy-duty vehicles (MTS OBG). This is driven by the limitations of traditional systems (mechanical and electro-hydraulic with centralized power), including low efficiency, complexity, weight, and reliability, especially in military applications. The research focuses on a hydrostatic AMM with volumetric speed control (variable speed electric drive + fixed displacement pump) and an involute actuator mechanism for a constant transmission ratio. Efficiency and reliability are enhanced through modular design and volumetric control. The work includes a functional diagram, mathematical model, design methodology, and experimental verification on a test bench
