AI Technical Summary

Technical Problem

In existing technologies, automotive Ethernet testing relies on third-party dedicated hardware devices, resulting in high expansion costs and poor flexibility in multi-node expansion and large-scale parallel simulation testing.

Method used

By generating client and server configuration records for each control device through a global configuration database, multiple control devices can send and receive data packets in parallel. The transmission performance is determined by the data transmission records fed back by the test device. A software-based centralized configuration and distributed parallel testing architecture is adopted to reduce dependence on third-party hardware devices.

Benefits of technology

Significantly reduces hardware investment and expansion costs of the testing system, enhances the expansion flexibility and scenario adaptability of the testing system, and enables large-scale multi-link parallel simulation testing.

Abstract

This application provides a method, device, and system for testing in-vehicle Ethernet. The method is applied to the testing device and includes: sending corresponding client configuration records and server configuration records to each control device in the vehicle according to a global configuration database, enabling each control device to send and receive data packets according to the rules corresponding to the client configuration records and server configuration records; receiving data transmission records sent by each control device; and determining the transmission performance of the data stream corresponding to each data stream type identifier based on the data transmission records sent by each control device. The centralized configuration of the global configuration database and the distributed parallel testing architecture enable simulation testing of data stream transmission from multiple control devices without relying on dedicated hardware, significantly reducing hardware investment and expansion costs for simulation testing. Simultaneously, the centralized configuration through the global configuration database allows for flexible configuration of control devices, effectively improving the scalability and flexibility of the test.
