AI Technical Summary

Technical Problem

In vehicle R&D and testing, the inconsistent CAN bus data formats of different manufacturers lead to low efficiency, inconsistent quality and poor universality in data model construction. Technicians spend a lot of time on tedious data preprocessing, which hinders the rapid iteration of models and cross-vehicle generalization.

Method used

By reading the raw log files, filtering messages using an ID whitelist, and combining the parsing rules of the DBC configuration file, signal decoupling and resampling are achieved, constructing structured vehicle data, and automating the transformation from raw data to model input.

Benefits of technology

Significantly reduces data processing volume, decouples signal definition and processing logic, supports cross-platform and cross-vehicle model migration, provides high-quality, standardized training data, and improves model development efficiency.
