Functional structure and algorithms of vehicle electromechanical braking system

Abstract

Introduction.  The development of electric vehicles is accompanied by a transition to electromechanical braking systems, which eliminate the need for traditional hydraulic drives. This requires the development of a structured architecture, software and control routines that ensure the joint, conflict-free operation of electromechanical braking system algorithms. The aim of this work is to develop a functional structure and software algorithms for a vehicle electromechanical braking system. Materials and Methods.  A method of functional software decomposition for the electromechanical braking system is applied, including groups for data reception and processing, control action generation, diagnostics and safety assurance, and data transmission. Results.  A functional software structure for the electromechanical braking system is proposed, which includes groups for data acquisition and processing, control action generation, diagnostics and safety assurance, and data transmission. A set of control algorithms for the requested braking torque has been developed.   Practical Significance.  The developed functional structure and algorithms can be used in the software design of electromechanical braking systems of electric vehicles, providing a structured representation of the entire software architecture for mechatronic systems. Originality.  Originality lies in the formulation of the functional software structure for the electromechanical braking system and the systematization of braking control algorithms, taking into account dynamic stabilization and the interaction between mechanical and regenerative braking.
