Android Automotive ist eine native Version von Android, die Google speziell für Autos angepasst hat. Sie kommt im Infotainment zum Einsatz, unter anderem bei Polestar und Renault, aber in den nächsten Monaten sind weitere Marken dabei.
Letztes Jahr wurde Version 12 von Android Automotive veröffentlicht und mit dem Release von Android 13 steht in diesem Jahr bereits Android Automotive 13 an. Es ist ein großes Update, ein sehr großes sogar, der Changelog von Google ist lang.
Ihr findet diesen am Ende des Beitrags.
Android Automotive und die Updates
Man merkt auch, dass da noch viele Basisfunktionen zu Android Automotive bei den Updates hinzugefügt werden und das OS relativ neu ist. Google legt aber auch ein ordentliches Tempo hin, denn Hersteller wie Polestar sind erst bei Version 11.
Android Automotive im Polestar 2
Ich weiß nicht, ob es so gut ist, dass Google da jedes Jahr ein großes Update wie bei Smartphones veröffentlicht. Autos sind komplexer. Die Update-Politik wird da sowieso eine spannende Sache und bisher sehe ich das doch noch etwas kritisch.
Polestar gibt sich viel Mühe und ist schnell und hat auch nur ein Auto mit Android Automotive, aber da kommt jetzt jedes Jahr ein neues Modell dazu. Wird man mit den Updates von Google mithalten können, wenn es schon jetzt schwierig ist?
Mal schauen, wie sich das noch entwickelt.
Android Automotive 13 Changelog
Camera
- Android camera2 API. Allows third party consumer apps to access one or more vehicle cameras concurrently without affecting the performance and behavior of the Extended View System (EVS).
- Enumerate camera devices by relative locations. Allows clients to enumerate and open camera devices (or video streams) according to relative locations, along with hardware details (for example, device node name) hidden from clients.
EVS hotplug events. Adds notification and handling of hotplug cameras.
Car Framework
- Car framework mainline. Added a new car framework module that includes car APIs and car services. This enables the updating of the car stack independent of Android platform versions.
- Driving safety region support. Allows apps to specify regions for driving safety and allows the system to specify a region and to provide a temporary waiver.
- Migrate the vehicle HAL from HIDL to AIDL. The HIDL HAL remains supported but new properties should only be added to new AIDL vehicle HAL.
- Support larger payload and batch calls in VHAL. VHAL can now pass larger payloads through shared memory. Batching calls allows for the more efficient sending of multiple requests.
- Navigation metadata filling for cluster. This feature extends the Navigation State Protocol Buffer in the Navigation State API with additional fields to describe navigation metadata.
- Touch mode. Notifications are now detached from focus events in Android 13. In Android 12 and earlier, focus and touch mode are represented by the same C++ native FocusEvent. Touch mode changes are now represented in a new event, TouchModeEvent. This new native event is dispatched against all existing windows, whether focused or not.
Connectivity
- Enable Ultra Wide Band (UWB). Provides multi-anchor support for locating UWB tags with an accuracy of 10cm.
- Bluetooth mainline integration. Turns Automotive Bluetooth into a module to enable updates independent of Android platform versions. Hidden APIs are migrated to system APIs with ongoing support from Google.
- Gabledorsch. A newer version of the Bluetooth stack is enabled, with support for automotive use cases.
- Vehicular networking. Adds controls for Ethernet-based networks, including dynamic management of IP configuration, network capabilities, application access control lists, and the ability to connect and disconnect networks on the fly.
- Reference TCU. Makes it more straightforward to integrate an external telematics ECU with Android through the Telephony HAL.
- Projection support. Added a new API to include VendorElements as part of a generated hostapd AP configuration.
- API to get a list of Wi-Fi channels and country codes when Wi-Fi is turned off.
Power
- Support Suspend-to-disk. Power-off mode to preserve the contents of RAM. Suspend-to-disk and Suspend-to-RAM are supported.
- Control of the shutdown process. Allows vendors to take timely actions before and after Garage Mode.
Privacy
- Permission model for auto. Changes to the permissions model balance safety, privacy and user experience while driving.
- Post-drive permission decision reminder. Reminds users who have parked of permission decisions made while they were driving.
- Recent permission decisions. Recent permission decisions are surfaced within Privacy Settings, enabling users to change mobiFlip permission decisions.
- Privacy dashboard for auto. Allows users to review recent app permission usage within Privacy Settings, including a timeline of events for sensors (such as location, microphone, and camera) and sub-attribution for GMSCore usage.
Sensors
- New sensor types in the Android sensor framework. Added new Inertial Measurement Unit (IMUs) sensor types for Limited Axes and Heading to support different sensor configurations and navigation use cases.
Telemetry
- OEM telemetry. Enables OEMs to use an Android-powered infotainment system to configure and collect In-Vehicle Infotainment (IVI) and vehicle data.
User Management
- Improved user lifecycle events management. Added a new user lifecycle filter to improve performance and simplify client code.
Vehicle Integration
- New VHAL properties. Added new properites for fog lights, EV charging, trailer, vehicle weight, and wheel tick.
