The vision for modern automotive software development
Modern cars are defined by safety, entertainment, and adaptability, requiring complex software for sensors, displays, and a holistic user experience.
#2about 3 minutes
Managing complexity in modern in-car HMI systems
Cars feature numerous sensors and displays for different contexts like driving and entertainment, creating a complex, heterogeneous setup that must provide a seamless user experience.
#3about 3 minutes
An overview of the automotive system architecture
The system architecture combines an Autosar platform for vehicle data with an HMI domain controller running a real-time OS for the instrument cluster and Android for infotainment.
#4about 1 minute
Understanding the difference between AAOS and Android Auto
Android Automotive OS (AAOS) is a full operating system running directly on the car's hardware, unlike Android Auto which is a projection app from a smartphone.
#5about 3 minutes
Building an infotainment system with Android Automotive OS
An AAOS build starts with the Android Open Source Project (AOSP), adds a board support package, OEM apps for customization, and can include Google Automotive Services (GAS) for a complete ecosystem.
#6about 3 minutes
A deep dive into the Android Automotive software stack
The AAOS software stack is built on a Linux kernel and includes a Hardware Abstraction Layer (HAL), the Android runtime, native libraries, and a framework layer for high-level services.
#7about 3 minutes
Understanding the three categories of AAOS applications
AAOS apps are categorized as default AOSP apps, custom OEM apps built with modern stacks like Kotlin and Compose, and third-party apps from the ecosystem.
#8about 2 minutes
Building third-party apps using the Car App Library
The Car App Library simplifies third-party development by providing a templated approach that handles driver distraction rules and different screen factors automatically.
#9about 2 minutes
Ensuring a consistent user experience with a theming engine
A theming engine provides a toolchain from design tools like Figma to the live product, using design tokens and resource overlays to customize the UI.
#10about 8 minutes
Answering questions on data, security, and development
The Q&A session covers topics such as Google's data collection, third-party app safety, CAN bus communication, development restrictions, and the permission model in AAOS.
