🔧 Automotive Software Architecture: An Advanced View Applied to TCU (Transmission Control Unit) Developing embedded software for modern automotive systems requires much more than writing functional code. It involves a deep understanding of vehicle dynamics, safety requirements, communication between modules, and integration with critical hardware. With this in mind, I have prepared a technical document that presents an advanced architecture in C language for a Transmission Control Unit (TCU) applied to CVT transmissions. The document explores everything from the modular structure of the software to essential aspects such as sensor acquisition, control logic, state machine, CAN communication, DTC diagnostics, and safety strategies — elements present in the daily work of real ECUs. The goal is to show, clearly and practically, how to organize robust, scalable embedded software aligned with best practices used in the automotive industry. For those who work with automotive electronics, validation, HIL, ECU integration, or firmware development, this content provides a concrete view of how these systems are structured in real life. #AutomotiveEngineering #EmbeddedSystems #AutomotiveSoftware #EmbeddedC #ECUDevelopment #TCU #CANBus #HILTesting #AutomotiveValidation #AutomotiveIndustry
