Abstract

This website presents the development of a generalized framework for implementing J1939 (or any application-layered CAN communication), designed for versatile application across various vehicle platforms. The framework is validated through both Hardware-in-the-Loop (HIL) testing and deployment on a real-world case study involving an electrified compact track loader. A custom Qt-based dashboard is developed to enable vehicle control and real-time monitoring of critical CAN signals, providing an intuitive interface for both development and diagnostics. The study explores the challenges of integrating J1939 with existing vehicle systems, offering insights into scalable solutions for off-road and heavy-duty electric vehicles. This work aims to contribute to the standardization of J1939 implementation, facilitating robust communication and efficient development workflows in automotive applications.

This framework assumes you have a DBC file from each component going into the vehicle.

🗂️ GitHub Branch Structure

The project repository is hosted at:
🔗 github.com/Sujeendra/ev-2025

The repository uses a structured branching strategy:

Branch Name Description
main ✅ Stable and tested version of the codebase. Safe to deploy and use.
feature 🚧 Contains new features that are almost ready for testing and integration.
fsm-branch ✅ Stable and tested version of the codebase with FSM. Safe to deploy and use.

Note: Always pull from main if you want a clean and working copy. Use experimental only for development and testing FSM extensions.
