Power automotive and autonomous driving AI from scenario mining to predictive maintenance
Zilliz Cloud is a fully managed vector database that powers driving scenario retrieval, corner case discovery, and sensor data similarity search for automotive AI teams â with millisecond latency across billions of embeddings. Engineering teams use it to find rare driving scenes in existing datasets instead of collecting new data, match HD map segments by semantic similarity, and detect anomalous vehicle behavior in real time. Proven in production at Bosch (80% reduction in data collection costs, ~$1.4M annual storage savings) and Volvo Cars. SOC 2 Type II certified.
AI Capabilities for the Next Generation of Automotive Intelligence
Every critical autonomous driving challenge is fundamentally a similarity problem: find scenes like this near-miss, find sensor readings that match this failure mode, find map segments similar to this construction zone, find driving patterns that deviate from normal. Zilliz Cloud gives automotive AI teams the infrastructure to solve these with true semantic similarity â at millisecond latency across petabyte-scale driving datasets.
Find Rare Corner Cases in Existing Driving Data
Encode camera, LiDAR, and radar captures as multimodal embeddings and search for semantically similar driving scenarios across petabytes of fleet data. Retrieve scenes matching 'pedestrian crossing in dense fog' or 'unexpected obstacle on highway' in seconds â recovering 70-80% of needed corner case data from existing databases instead of mounting expensive new data collection campaigns.
Search Driving Scenes by Meaning, Not Metadata Tags
Embed driving scenes using large vision models and retrieve similar scenarios via text-to-image or image-to-image search. Move beyond brittle keyword tags and manual annotations to semantic understanding â finding scenes where 'a cyclist merges into traffic at dusk' without requiring that exact label to exist in your annotation pipeline.
Match and Update HD Map Segments by Semantic Similarity
Embed HD map tiles and road segments as vectors to find semantically similar map regions across geographies. Detect when a newly observed road segment differs from its stored HD map representation, prioritize map update regions by deviation severity, and transfer learned representations from well-mapped areas to newly surveyed zones.
Detect Anomalous Sensor Patterns Before They Cause Failures
Embed multi-sensor fusion outputs as vectors where normal driving patterns cluster tightly and anomalies appear as outliers. Identify sensor degradation, calibration drift, and hardware failures by detecting deviations from expected embedding distributions â catching problems that rule-based thresholds miss because they manifest as subtle pattern shifts rather than simple threshold breaches.
Predict Component Failures from Fleet-Wide Behavioral Patterns
Encode vehicle telemetry streams â vibration signatures, thermal profiles, electrical patterns â as time-series embeddings and search for similar degradation trajectories across your entire fleet history. Match a vehicle's current behavior pattern to known pre-failure signatures, enabling condition-based maintenance that reduces unplanned downtime and warranty costs.
Enable Real-Time Similarity Search Across Connected Vehicle Networks
Embed vehicle-to-everything communication data and search for similar traffic patterns, hazard signatures, and road conditions across connected vehicle fleets. When one vehicle encounters black ice or a road hazard, find all vehicles approaching similar conditions in real time â turning fleet-scale sensor data into collective situational awareness.
Why Zilliz?
Why automotive AI teams choose Zilliz Cloud
Autonomous driving development has three infrastructure requirements that most data systems cannot meet simultaneously: millisecond-latency retrieval to support real-time perception and decision loops, scale to handle billions of sensor embeddings from petabyte-scale driving datasets, and multimodal search across camera images, LiDAR point clouds, radar returns, and textual descriptions in a unified query. Traditional data mining tools cannot handle the spatiotemporal understanding, multi-sensor fusion, and contextual reasoning that AV systems demand. Bosch's Intelligent Drive Control team deployed Milvus to search corner case imagery across their driving data lake â retrieving 70-80% of needed scenarios from existing data, cutting data collection costs by 80%, and saving ~$1.4M annually in storage costs. Volvo Cars adopted Milvus for its ease of integration and execution across their vehicle data workflows.
80%Cost Reduction
Reduce data collection costs by finding corner cases in existing data
Bosch reduced data collection costs by 80% by using Milvus to search existing driving databases for corner case imagery instead of mounting new collection campaigns. With 70-80% of needed rare scenarios already present in fleet data, vector search eliminates the most expensive part of autonomous driving development â acquiring new labeled data.
<1sRetrieval Speed
Search billions of sensor embeddings in milliseconds
Autonomous driving datasets grow by terabytes daily. Zilliz Cloud delivers millisecond-level retrieval across billions of vectors â enabling same-day discovery of specific driving scenarios that previously took weeks of manual search. Engineers query by text description or reference image and get results instantly.
10B+Scale
Index petabyte-scale driving datasets in a single deployment
A single test vehicle generates 1TB of data per hour. A 100-vehicle fleet running 8 hours daily produces overwhelming data volumes. Zilliz Cloud supports tens of billions of vectors in a single index â your entire fleet's driving history, sensor archive, and scenario library searchable together without sharding across multiple systems.
MultiModality
Search across cameras, LiDAR, radar, and text in one query
Autonomous driving is inherently multimodal. Zilliz Cloud supports cross-modal search â query with a text description and retrieve matching camera frames, search with a LiDAR point cloud pattern and find similar radar signatures. Large vision models and multimodal embeddings unite all sensor modalities in a single vector space.
Hybrid search with structured metadata filtering
Combine semantic vector similarity with structured filters â retrieve driving scenarios filtered by weather condition and time of day, search sensor data filtered by vehicle model and geographic region, or find corner cases filtered by severity and road type. One query, both signals.
Tiered storage for hot and cold driving data
Recent fleet data stays in memory for instant retrieval. Older driving logs move to SSD and object storage automatically. Zilliz Cloud's tiered storage reduces costs by over 70% for petabyte-scale archives while maintaining sub-second access when cold data is needed â critical for automotive teams managing hundreds of petabytes.
Multimodal embedding support
Embed camera images, LiDAR point clouds, radar returns, and textual scene descriptions into a shared vector space using models like CLIP and ImageBind. Cross-modal retrieval enables text-to-image scenario search, image-to-image similarity, and sensor-to-sensor pattern matching in a unified system.
Cloud-native elastic scaling
Training campaigns and validation runs create massive burst workloads. Scale compute up during model training data curation and back down during steady-state operation. Pay only for what you use â critical for automotive R&D teams with variable and unpredictable infrastructure demands.
Enterprise security and data residency
SOC 2 Type II certified, GDPR compliant, 99.95% SLA. BYOC deployment keeps sensitive driving data and proprietary models within your own cloud account â essential for automotive OEMs with strict IP protection, data sovereignty, and regulatory compliance requirements.
Real-time index updates without downtime
Fleet vehicles generate new sensor data continuously. Zilliz Cloud supports high-throughput vector ingestion without performance degradation â keeping your scenario database current as new driving data streams in from vehicles in the field, not batched hours or days later.
