Overview

Sonatus Updater is a unified, secure xOTA (cross-OTA) management solution for automotive OEMs that centralizes and automates distribution of firmware, containers, AI models, configuration data and policies across vehicle fleets. It provides cloud-based simulated dry-runs to predict data size and campaign cost, enforces package signing and encryption for cybersecurity and regulatory compliance, and delivers end-to-end visibility and traceability down to individual ECUs to simplify debugging and auditability.

Features and Capabilities

• Unified update types: Supports firmware, containers, AI models, variant coding, configuration data and policy updates from a single management console, enabling a single pane of glass for heterogeneous vehicle assets. The product handles diverse asset formats beyond traditional ECU firmware.
• Simulated dry-runs & predictability: Cloud simulation of update campaigns to estimate data usage, network/campaign cost, detect conflicts and predict success rates before live deployments.
• Security & compliance: Enforces package signing, encryption, and verification in-vehicle and is designed to support regulatory and cybersecurity needs (e.g., compliance workflows for automotive regulations).
• End-to-end traceability: Detailed campaign logging and traceability down to the ECU level — enabling precise troubleshooting, auditing, and rollback analysis for each vehicle.
• Scalability & fleet targeting: Fine-grained campaign controls to target sub-fleets or individual vehicles, schedule staged rollouts, and manage large fleets with operational controls for throttling and bandwidth optimization.
• Conflict detection & resolution: Automated checks to detect software/configuration conflicts across ECUs and variants, plus tools to resolve or quarantine problematic packages prior to deployment.
• Operational analytics & reporting: Visibility into campaign health, success/failure metrics, cost prediction and historical reporting to inform release policies and improve success rates.
• Integration & ecosystem: Designed to integrate with vehicle cloud services, data collection and CI/CD toolchains, enabling DevOps-style update workflows for SDVs.
• Developer & OEM tooling: APIs and interfaces for automated package creation, signing, orchestration and integration into existing OEM supply-chains and validation pipelines.
• Auditing & troubleshooting tools: Detailed logs, rollback mechanisms and per-vehicle diagnostics to speed root-cause analysis and recovery for failed updates.
