The scale of vehicle architecture
Vehicle architecture has evolved over the years, transitioning from a distributed architecture to a more centralized one. This shift aims to support new technologies and features, including connected vehicles, software-defined vehicles, 5G, and IoT use cases such as efficient remote diagnostics and Phone as a key (which was introduced in Chapter 2, Introducing Automotive IoT Use Cases). This evolution also optimizes the hardware and expands the software scope, which, in turn, reduces the product’s overall cost and improves the upgradability and maintainability aspects of the product. For example, remote diagnostics can identify issues without the need to perform a physical inspection, while OTA updates allow for seamless software enhancements.
Distributed architecture
Distributed architecture is widely employed in traditional vehicles and is where each ECU is responsible for one function, such as audio. These ECUs communicate over the...
