本页总结了 Android Automotive 13 中提供的主要新功能。
功能
相机
- Android camera2 API。允许第三方消费类应用同时访问一个或多个车载摄像头,而不会影响 Extended View System (EVS) 的性能和行为。
- 按相对位置枚举摄像头设备。允许客户端根据相对位置枚举和打开摄像头设备(或视频串流),以及对客户端隐藏的硬件详细信息(例如,设备节点名称)。
- EVS 热插拔事件。添加了有关热插拔摄像头的通知和处理。
汽车框架
- 汽车框架 Mainline。添加了包含汽车 API 和汽车服务的新汽车框架模块。这样即可独立于 Android 平台版本更新汽车堆栈。
- 驾驶安全区域支持。允许应用指定驾驶安全区域,并允许系统指定区域并提供临时豁免。
- 将车载 HAL 从 HIDL 迁移到 AIDL。HIDL HAL 仍受支持,但新属性只应添加到新的 AIDL 车载 HAL。
- VHAL 中支持更大的载荷和批量调用。VHAL 现在可以通过共享内存传递更大的载荷。通过批量调用,可以更高效地发送多个请求。
- 对车载仪表盘进行导航元数据填充。此功能添加了用于描述导航元数据的额外字段,从而扩展了 Navigation State API 中的 Navigation State Protocol Buffer。
- 轻触模式。在 Android 13 中,通知现在已与焦点事件分离。在 Android 12 及更低版本中,焦点模式和轻触模式由相同的 C++ 原生 FocusEvent 表示。现在,轻触模式更改将以
TouchModeEvent
这一新事件表示。系统会针对所有现有窗口分派这项新的原生事件,无论窗口是否聚焦。
连接
- 启用超宽带 (UWB)。提供多锚点支持,用于以 10 厘米的精度定位 UWB 标记。
- 蓝牙 Mainline 集成。将 Automotive 蓝牙转换为一个模块,以实现独立于 Android 平台版本更新蓝牙。在 Google 的持续支持下,隐藏的 API 已迁移到系统 API 中。
- Gabledorsch。启用了新版本的蓝牙堆栈,支持汽车用例。
- 车载网络。针对基于以太网的网络添加了相应控件,包括动态管理 IP 配置、网络功能、应用访问控制列表,以及快速连接网络和断开网络连接的功能。
- 参考 TCU。使通过 Telephony HAL 将外部远程信息处理 ECU 与 Android 集成变得更简单。
- 投影支持。添加了一个新 API,以将
VendorElements
添加为生成的 hostapd
AP 配置的一部分。
- 用于在 Wi-Fi 处于关闭状态时获取 Wi-Fi 信道及国家/地区代码列表的 API。
电源
- 支持“挂起到磁盘”。用于保留 RAM 内容的关机模式。
支持“挂起到磁盘”和“挂起到 RAM”。
- 控制关闭进程。允许供应商在车库模式之前和之后及时执行操作。
隐私设置
- 适用于 Auto 的权限模型。针对权限模型的一些变更,可平衡驾驶期间的安全性、隐私性和用户体验。
- 驾驶后权限决策提醒。在用户停车后,就用户在驾驶期间做出的权限决策向用户发出提醒。
- 最近的权限决策。最近的权限决策会显示在“隐私设置”中,让用户能够更改权限决策。
- 适用于 Auto 的隐私信息中心。允许用户在“隐私设置”中查看最近的应用权限使用情况,其中包括传感器(例如位置信息、麦克风和摄像头)的事件时间轴以及 GMSCore 使用情况的次级归因数据。
传感器
- Android 传感器框架中添加了新的传感器类型。针对 Limited Axes and Heading 添加了新的惯性测量装置 (IMU) 传感器类型,以支持不同的传感器配置和导航用例。
Telemetry
- OEM 遥测。使原始设备制造商 (OEM) 能够使用由 Android 提供支持的信息娱乐系统来配置车载信息娱乐系统 (IVI),并收集该系统的相关数据和车辆数据。
用户管理
- 改进了用户生命周期事件管理。添加了新的用户生命周期过滤器,以提高性能并简化客户端代码。
车辆集成
- 添加了新的 VHAL 属性。添加了针对雾灯、电动汽车充电、拖车、车辆重量和车轮计数的新属性。

This enables the updating of the car stack independent of Android platform versions.\n- **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.\n- **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.\n- **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.\n- **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.\n- **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.\n\n### Connectivity\n\n- **Enable Ultra Wide Band (UWB).** Provides multi-anchor support for locating UWB tags with an accuracy of 10cm.\n- **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.\n- **Gabledorsch.** A newer version of the Bluetooth stack is enabled, with support for automotive use cases.\n- **Vehicular networking.** Adds controls for Ethernet-based networks, including dynamic management of IP configuration, network capabilities, app access control lists, and the ability to connect and disconnect networks on the fly.\n- **Reference TCU.** Makes it more straightforward to integrate an external telematics ECU with Android through the Telephony HAL.\n- **Projection support.** Added a new API to include `VendorElements` as part of a generated `hostapd` AP configuration.\n- **API to get a list of Wi-Fi channels and country codes when Wi-Fi is turned off.**\n\n### Power\n\n- **Support Suspend-to-disk.** Power-off mode to preserve the contents of RAM. Suspend-to-disk and Suspend-to-RAM are supported.\n- **Control of the shutdown process.** Allows vendors to take timely actions before and after [Garage Mode](/docs/automotive/power/garage_mode).\n\n### Privacy\n\n- **Permission model for auto.** Changes to the permissions model balance safety, privacy and user experience while driving.\n- **Post-drive permission decision reminder.** Reminds users who have parked of permission decisions made while they were driving.\n- **Recent permission decisions.** Recent permission decisions are surfaced within Privacy Settings, enabling users to change permission decisions.\n- **Privacy dashboard for auto.** Lets users 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.\n\n### Sensors\n\n- **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.\n\n### Telemetry\n\n- **OEM telemetry.** Enables OEMs to use an Android-powered infotainment system to configure and collect In-Vehicle Infotainment (IVI) and vehicle data.\n\n### User management\n\n- **Improved user lifecycle events management.** Added a new user lifecycle filter to improve performance and simplify client code.\n\n### Vehicle integration\n\n- **New VHAL properties.** Added new properties for fog lights, EV charging, trailer, vehicle weight, and wheel tick."]]
