Abstract

The invention relates to a CANFD controller software remote upgrade test method and system based on an L3 whole vehicle framework. The method specifically comprises the steps of ECUS monomer FBL test, GW-ECUS integration test, THU-GW integration test, THU-GW-ECUS integration test and TSP-THU-GW-ECUS system integration test. According to the CANFD controller software remote upgrading test technology based on the L3 whole vehicle framework, it can be guaranteed that the software to be used for remote upgrading is reliable and stable, the test of the CANFD controller software remote upgrading based on the L3 whole vehicle framework becomes possible, and the test blank is filled up.

Description

technical field [0001] The invention belongs to the technical field of automobile electrical appliances, and in particular relates to the remote upgrade test technology of CANFD controller software based on L3 vehicle architecture. Background technique [0002] With the rapid development of automobile intelligence and networking, the demand for embedded software has shown a blowout growth, and "software-defined cars" has become a trend. However, the traditional software upgrade method (requiring users to go to the 4S store to software upgrades) can no longer meet the current software iteration needs, and it is necessary to develop a software for remote upgrades to meet the needs of software upgrades anytime and anywhere, but the software itself must be reliable and stable, so in order to ensure that the software quality is up to standard, it is necessary to Test the software, but currently there is no upgrade testing technology for the CANFD controller software based on the ...
