ADVANTAGES

Advantages

01Rapid diagnosis

Problem analysis drops from 3 hours to 30 minutes, locating root causes in minutes.

02Full data coverage

Handles CAN/CAN FD, Ethernet and LIN data as well as DTC fault code decoding.

03Reuse of experience

Links historical faulty versions with their solutions and builds a company-specific diagnostic knowledge base.

04Hardware and software together

Together with ZD Datalogger logging hardware, signal bug localisation falls from hours to minutes.

TECH STACK

Technology Foundation

01LLM engine

A large language model serves as the reasoning core, tuned on automotive R&D and testing corpora to support requirement parsing, root cause reasoning and code generation.

02Industry knowledge base + RAG

Brings together ZD simulation knowledge, historical fault cases and diagnostic experience with retrieval-augmented generation, so output matches real engineering contexts.

03On-premises deployment

Supports local and private-cloud deployment so R&D data never leaves the company, meeting OEM data security and compliance requirements.

04Closed-loop automated execution

Agent output connects directly to test execution, simulation scheduling and ticketing systems, so results flow automatically and are tracked to closure.

CASES

Deployments

01Leading NEV manufacturer · AI fault diagnosis system

Covers 87% of common cockpit faults. Handling time drops from 4-8 hours to under 30 minutes, engineer productivity rises about 4x and knowledge reuse increases by 60%.

02ZD Datalogger intelligent analysis · Signal bug localisation

BLF, ASCL and MAT logging files feed the AI engine automatically for timing anomaly detection and value-range compliance checks: 90% detection for common signal bugs and 90% for suspicious signals, with localisation down from hours to minutes.
