AI Technical Summary

Technical Problem

Existing technologies cannot effectively detect cross-bus routing, which leads to the failure to detect data interaction failures between different bus systems in a timely manner, resulting in the failure of coordination between various vehicle systems, functional abnormalities, and even safety hazards.

Method used

By acquiring the source and destination ends of each routing link in the vehicle, target links that do not belong to the same bus are filtered out. The source end of the target link is simulated to generate and send a test signal, and it is determined whether the signal received at the destination end is consistent with the test signal, thus realizing the detection of cross-bus routing.

Benefits of technology

It can promptly detect data interaction faults between different bus systems, prevent the failure of coordination between vehicle systems and functional abnormalities, and reduce safety hazards.

Abstract

The embodiment of the invention provides a cross-bus route detection method and device, electronic equipment and a storage medium. The cross-bus route detection method comprises the steps of obtaining a source end and a destination end of each route link in a vehicle; determining a routing link of which the corresponding source end and target end do not belong to the same bus as a target link; simulating a source end of the target link to generate a test signal, and sending the test signal through a bus to which the source end of the target link belongs; and judging whether the to-be-detected signal received by the destination end of the target link is the same as the test signal, if so, judging that the routing detection result of the target link is normal, and if not, judging that the routing detection result of the target link is routing failure. According to the method, targeted detection is carried out on the cross-bus routing link, the limitation that the prior art is limited to a single bus detection scene is broken through, data interaction faults among different bus systems can be found in time, cooperative failure and functional abnormality of the systems of the vehicle are avoided, and potential safety hazards are reduced.
