This post describes edge computing for automotive ECUs.
As shown in the table below, automotive ECU edge computing consists of a central ECU and edge ECUs. The central ECU issues commands, and the edge ECUs perform the actual control operations and sensing.
| Item | Central ECU | Edge ECU |
|---|---|---|
| Role | Coordination with the other systems | Conversion from sensor values to physical = measured values |
| Calculation of control targets for the edge ECUs | Actuator control based on control targets and measured values | |
| Transmission of target values to the edge ECUs | Transmission of measured values and diagnostic results to the Central ECU | |
| System Diagnostics and fail-safety | – Diagnostics and fail-safe | |
| Communication to: | Edge ECUs | Central ECU |
| Central ECU inside the system* | – | |
| Central ECU outside the system* | – |
* System
Power Train, chassis, Body, ADAS, etc
