Abstract

The paper deals with mechatronic systems and communication among mechatronic modules. This article proposes possible solution of usage open CAL protocol above CAN bus, which is independent from any manufacturers and can be widely accepted themselves. The main attention is paid to open CAN/CAL protocols including the viewpoint of their implementation, essential functions and potential integration within the vehicle control system. The required communication functions, communication models, communication objects (PDO, SDO) and applied profiles are being described in the CAL protocol. As an example a double bus CAN system is shown as a typical CAN/CAL solution for mechatronic systems in automotive industry.

Highlights

  • Mechatronics is the cooperation of mechanical engineering (“mecha” for mechanisms), electronic engineering (“tronics” for electronics), and software engineering

  • This article deals with the specific communication requirements of the mechatronic modules

  • The main intention was paid on the possible solutions for communication of the open mechatronic systems

Summary

Introduction

Mechatronics is the cooperation of mechanical engineering (“mecha” for mechanisms), electronic engineering (“tronics” for electronics), and software engineering. The purpose of this interdisciplinary engineering field is the study of automats from an engineering perspective and serves to view the control of advanced hybrid systems (Wikipedia), see Figure 1. The distributed control production system utilises CAN (Controller Area Networks) and VAN (Vehicle Area Networks) to link and integrate autonomous mechatronic modules
