The test data from the multiple domains are processed by timestamp alignment and feature fusion to obtain the whole vehicle domain data; The vehicle domain data is subjected to preset test result decision processing to obtain the vehicle domain data analysis results; A vehicle test report is generated based on the vehicle domain data and the analysis results of the vehicle domain data.

9. The method according to claim 8, characterized in that, The aforementioned test strategy, based on a preset testing strategy, performs domain testing on the target vehicle to obtain multiple domain test data, including: Based on a preset testing strategy, the target vehicle is subjected to powertrain and chassis domain testing to obtain first domain test data, network connectivity domain testing to obtain second domain test data, body and cabin domain testing to obtain third domain test data, and fault injection testing to obtain fourth domain test data.

10. The method according to claim 8, characterized in that, The step of performing preset test result decision processing on the vehicle domain data to obtain vehicle domain data analysis results includes: Obtain real vehicle test data; Based on the actual vehicle test data, the whole vehicle domain data is subjected to preset test result decision processing to obtain the whole vehicle domain data analysis results.
