Standardized In-vehicle Communication Networks in Off-road Vehicles [LS10047]

Content

In the module, a full stack of communication technology is studied. The content is:
- topology and physical layer of tractor-implement communication, OSI model
- basics of CAN bus, including protocol, addressing, bus arbitration and bit stuffing
- history of multi-brand tractor-trailer interoperability, original design requirements
- addressing in vehicle networks, function and manufacturer codes
- tractor ECU functionality, for tractor-implement automation
- task controller ISOBUS functionality, for precision farming
- diagnostics methods in vehicle networks
- middlewares for future system design in modular vehicles

Prerequisites

Recommended prerequired knowledge involves basic mathematics, basic software development skills and basics of electric circuits. It is recommended to study the module WZ1295 Positioning and Navigation for Off-Road Vehicles before this module, to gain required basic Matlab programming skills.

Learning Goals

After completion of the module, the students are familiar with the core technologies related to vehicle communication. They gain deep understanding of wiring and topology principles.
Students are able:
• to describe principles of communication networks, like physical layer and topology
• to describe the communication layers of vehicle communication networks
• to describe bus arbitration principles of network access
• to debug the network communication at protocol level
• to create small software programs that interconnect in the same vehicle network
• to design communication requirements for application in modular vehicle systems.
• to describe a middleware communication channel, and the benefits of using such in a future system.
