AI Technical Summary

Technical Problem

Existing CAN bus testing solutions suffer from single-dimensional and static interference, making it impossible to precisely control the timing of bit-level interference, resulting in poor real-time performance and limited testing capabilities.

Method used

An interference IP core for CAN bus testing is provided, including a bus monitoring module, a policy scheduling module, and an interference execution module. It monitors communication data in real time, adaptively schedules interference policies and executes interference operations according to preset interference configuration parameters.

Benefits of technology

It achieves dynamic response to adaptive interference, improves the comprehensiveness and depth of CAN bus testing, and enhances the reliability and security of automotive control networks.

Abstract

The application belongs to the technical field of automobile electronic communication network testing, and particularly relates to an interference IP core and an interference method for CAN bus testing, wherein the interference IP core for CAN bus testing comprises: a bus monitoring module configured to monitor communication data on the CAN bus in real time, so as to analyze the content of each CAN frame in real time and obtain the bus load rate; a strategy scheduling module configured to compare the content of each CAN frame and the bus state with preset interference configuration parameters, and if the comparison result meets the interference triggering condition, the corresponding interference strategy is scheduled; and an interference execution module configured to execute the interference operation according to the interference strategy.
