Smart Diagnostics

The transformation of automotive diagnostic systems is reshaping the aftermarket ecosystem. In research and development, AI-driven simulation testing is gradually becoming mainstream. In manufacturing, digital twins combined with large industrial models have enabled predictive maintenance. In the service sector, applications like large models are progressively achieving a fully AI-automated process from "voice/photo description of fault phenomena -- cloud AI system self-check -- downloading diagnostic manuals and methods -- scheduling repairs."

Diagnostic data will become one of the core competencies for automakers, acting as the "digital blood" driving the evolution of the automotive ecosystem. For instance, insurance companies can leverage this data to customize more precise Usage-Based Insurance (UBI); used car platforms can achieve more accurate residual value assessments through comprehensive vehicle health records; and automakers can capture directions for improving their next-generation products from vast amounts of data. These data assets not only optimize product design but also foster new business models, such as subscription-based diagnostic services.

Carota's "Remote Diagnostics" function includes diagnostic script editing and management, diagnostic task management, data collection and analysis, diagnostic log management, and early warning monitoring. Our expert system provides fault monitoring dashboards, fault code scanning, fault snapshot collection, root cause analysis, etc., demonstrating a higher standard on the platform.

The "Smart Diagnostic Platform," on the other hand, covers knowledge graph updates and retrieval, smart diagnostic Q&A, smart guided troubleshooting, and the generation of repair recommendations. This helps automotive manufacturers and fleet operators remotely monitor vehicle health, proactively resolve potential issues to prevent sudden breakdowns. By continuously learning from large models, it assists automakers in continuously improving vehicle maintenance and operational efficiency.

  • Real-Time Monitoring

    Continuously tracks vehicle performance to identify early signs of abnormalities or faults.

  • Predictive Maintenance

    Utilizes AI algorithms to predict potential malfunctions, reducing downtime and maintenance costs.

  • Comprehensive Insights

    Provides detailed diagnostic information covering all critical systems, including the engine, battery, and communication modules.

  • Enhanced Safety

    Alerts automakers to urgent issues, ensuring timely resolution and improving vehicle reliability.

Whole-Vehicle OTA Simulation & Testing

Background：In the era of Software-Defined Vehicles (SDVs), software quality has become the core of product competitiveness. Carota provides whole-vehicle OTA simulation, emulation, and testing services and equipment, assisting automakers in pre-verifying update behaviors during the development phase. This effectively reduces system errors and risks, ensures stable improvements in functionality and performance, and accelerates mass production readiness and time-to-market.

Pain Point：To ensure the proper delivery of OTA functionality for a project, comprehensive system testing is required to fully validate the OTA module's functions.

Goal：Through system testing and verification, ensure product quality meets product requirements, functions are correctly implemented, and performance and security comply with release standards, allowing the product to go live as scheduled.

Effectiveness：Effectively reduces post-launch risks for the entire vehicle, enhances product quality, and meets consumer expectations for vehicle use.

Carota provides an OTA simulation and testing platform, paired with test cabinet hardware and software, facilitating various simulations and validations of OTA deployment before vehicle rollout.
