A comprehensive automotive software development project demonstrating AUTOSAR architecture, CAN communication protocols, and modern C++ embedded systems programming. This project showcases production-ready automotive software patterns suitable for ECU development and embedded systems roles.
The autosar-cpp directory contains a production-style AUTOSAR architecture with Software Components (SWCs), Runtime Environment (RTE), and port-based communication. It demonstrates modern C++20 with automotive best practices, concepts for type safety, designated initializers, smart pointers, and thread-safe programming. The implementation includes realistic automotive features such as engine control, body control, auto-lighting, and CAN messaging, along with a professional build system using CMake.
The project includes Software Components for engine control (10Hz) and body control (2Hz) with proper AUTOSAR lifecycle management. The Runtime Environment provides thread-safe data routing, scheduling, and port connection management. CAN communication is implemented with automotive message formats, encoding/decoding, and realistic protocol simulation. Inter-component communication demonstrates type-safe data exchange between ECUs via RTE ports, with real-time scheduling that matches deterministic execution patterns found in production automotive systems.

The system consists of multiple Vehicle ECUs communicating through a CAN Network. The Engine ECU handles RPM control, temperature monitoring, and throttle management. It communicates with other components via the CAN Network, which manages message IDs, data encoding, and bus arbitration.
The AUTOSAR Runtime Environment (RTE) serves as the central coordination layer, connecting the Engine ECU with the Body Control module and other ECUs. The Body Control ECU manages door status, lighting systems, and auto features, while other ECUs in the system include gateway modules, diagnostics, and infotainment systems.
