Inter and Intra ECU Communication

The communication between the application software component can be:-

1. Inter ECU
2. Intra ECU

• The interaction between the ECU I and ECU II is an example of Inter ECU communication and takes place through and beneath the RTE, and goes via Basic Software Module(BSW).
• The BSW handles the functions like interaction with the Memory, Diagnostics, along with communication services(if needed) for the inter ECU communication.
• The intra ECU communication is within the ECU between the Software Component B (SW-C B) and the Software Component C (SW-C C) is entierly through the RTE.
