Nexus-SDV uses Bigtable, Android Automotive for agentic vehicles

By linking this on-vehicle service layer managed by Nexus SDV with historical fleet telemetry stored in Bigtable, you deliver deeply integrated experiences that unlock new mobility solutions. Now let’s take a quick look at the Cloud side.

The Google Cloud side: AI-native mobility

Beyond SDV, we are rapidly moving toward AI-defined vehicles, or AIDV, where AI is core to a vehicle’s operational logic. To be AI-native means being autonomous by design, with AI embedded at every architectural level. With this level of AI, the system can perceive environments, reason through complex scenarios using engines like Google Gemini, and proactively execute actions. For example, a Gemini-powered vehicle doesn’t just warn you that you’re low on power; it analyzes your schedule, traffic, and charger availability to suggest an optimized charging stop that pre-conditions the battery for maximum efficiency. This is the level of contextual understanding and proactive automation that characterizes AIDV.

Compare this to legacy architectures, which weren’t designed to capture the volume and variety of data coming from different systems across the vehicle. This can lead to data silos of isolated maintenance and safety information telematics. Moreover, because this data is fragmented, it can be very difficult to get cohesive value from the data across systems. An AI-native approach can help collapse these silos, providing a unified contextual understanding. This solves a primary OEM pain point: the massive complexity of managing high-bandwidth telemetry from multiple sources like SDV telematics. 

Bigtable: The data backbone for Automotive Telemetry

Bigtable was purpose-built for the massive ingestion rates and sub-millisecond latency requirements, and serves as the data backbone for petabyte-scale automotive and manufacturing telemetry datasets. In fact, Bigtable is already being used to support business critical automotive telemetry solutions. Its flexible, sparse-row schema allows OEMs to evolve their data models without downtime, accommodating diverse sensor arrays — from high-frequency engine metrics to LiDAR point clouds — within a single, unified table structure. Then, by versioning time-series events in a way that is natively optimized for both massive writes and complex, multi-dimensional analytical lookups, Bigtable helps avoid the data overload typical of legacy systems.

Meanwhile, features like Continuous Materialized Views (CMV) allow for pre-calculating key metrics, such as average battery temperature or fleet-wide torque distributions, directly within the storage layer, minimizing computational overhead. Bigtable’s integration with Agent Development Kit (ADK) further bridges the gap between data and action by giving AI agents access to data. This kit combined with Bigtable’s integrations with frameworks like Apache Spark help monitor the “firehose” of live telemetry data and trigger automated workflows in real time, e.g., logging mission-critical alerts, initiating proactive over-the-air (OTA) software adjustments, or pre-ordering replacement parts, the moment specific degradation patterns are detected.

Bring it all together: Nexus-SDV platform

The Nexus SDV platform is built on Google Cloud and integrated with AAOS SDV, supporting the future of connected vehicles. By providing a standardized data foundation, Nexus empowers automotive OEMs to go beyond building infrastructure from scratch and start focusing on unique brand experiences.

Nexus SDV uses Google components like Gemini Enterprise Agent Platform, Bigtable, and BigQuery. Setting up Nexus SDV is quick, automated and transparent. OEMs can create  brand-specific customer experiences in the vehicle, as well as in other customer touch points such as the UI screen, mobile app, or service centers.  The connection to the vehicle is accomplished by leveraging the open source Synadia NATS interface. This integration with the vehicle is facilitated through simple Cloud and vehicle SDKs, for service discovery on both sides. Nexus SDV is optimized for AAOS SDV, but can integrate with any vehicle framework.
