Problems solved by technology

It is mainly to check whether the message signal can be forwarded correctly. The test method is relatively simple, but the test coverage is low, and the change of the message signal cannot be simulated. The change of the message signal can only be realized by controlling the relevant operations of the vehicle, and the test scene is limited.
[0005] The existing gateway routing test can only carry out simple CAN-CAN gateway routing test and CAN-LIN gateway routing test. There is no relevant routing test experience for the new multimedia bus MOST bus. The existing gateway routing test platform cannot be used universally, and the scalability is not strong. , and there is no similarity

Abstract

The invention relates to a gateway routing automatic test system and a test method based on CAN / LIN / MOST hybrid buses. The system and the method are characterized in that principal computer software loads a user defined gateway routing information table and automatically parses routing information, and a CAN / LIN / MOST bus acquisition tool simulates and acquires message signals of different buses for CAN-CAN, CAN-LIN and MOST-CAN gateway routing automatic test. Both gateway routing test between buses of the same type and gateway routing test between buses of different types are realized. The system and the method are of high versatility and are scalable. Through automatic test by the principal computer software and other software, the shortcomings of manual test are overcome, and the accuracy, reliability and working efficiency of gateway routing test are improved greatly.

Description

technical field [0001] The invention relates to a CAN / LIN / MOST hybrid bus gateway routing automation test system and a test method, which belong to the field of vehicle controller bus test. Background technique [0002] With the rapid development of the automotive electronics industry, the vehicle bus network is becoming more and more complex, and a hybrid multi-channel bus network is often used for the development of electronic and electrical architectures. Gateways are required to forward packets and signals between different network segments, so as to realize information exchange between different network segments. In order to ensure that the gateway can correctly forward relevant messages and signals in a timely manner, the gateway needs to be tested and verified before loading. [0003] The existing gateway routing test is basically done through manual testing. By simulating the message received by the gateway in the gateway routing table with the bus tool, it is check...
