Automobile CAN gateway routing bench test method and system

Abstract

The invention relates to the technical field of automobile bus communication, and provides an automobile CAN gateway routing rack test system, which comprises a test channel selection module for selecting an untested CAN channel from six CAN channels as a current test CAN channel; a test module which is used for periodically sending a set number of test frames to the gateway route through the test CAN channel, and forwarding the test frames sent by the test CAN channel to the CAN channel corresponding to the test CAN channel through the gateway route; and a recording module which is used for recording test frame receiving time and/or test frame sending time of all CAN channels in real time. After the six CAN channels are tested, all data recorded by the recording module are output through the display module, verification of routing forwarding of the six CAN gateway signals is automatically completed, missed sending or missed forwarding of test frames is avoided, test data of all the test CAN channels can be automatically recorded in the test process, and the engineer can conveniently evaluate the performances such as the leakage conversion rate and the error conversion rate of the gateway routing based on the test data.

Description

technical field [0001] The invention relates to the technical field of automobile bus communication, and provides an automobile CAN gateway routing bench testing method and system. Background technique [0002] With the emergence of smart cars, customers have higher and higher requirements for car smart services, and the integration of vehicle ECU modules is becoming more and more powerful. At this time, the network architecture topology is expanded from traditional power CAN and body CAN to increase information CAN, Information CAN, chassis CAN, diagnosis CAN, as the gateway routing and forwarding is also upgraded from the traditional 2-way CAN to support at least 6-way CAN, the gateway signal path is becoming more and more complicated, and the CAN routing and forwarding verification is carried out through the traditional artificial bench. Not only the test efficiency is low, but also the problem of signal leakage or leakage is prone to occur. Contents of the invention ...
