Abstract

The invention provides a test method and device for an automatic driving vehicle data recording system. The test method comprises the following steps: receiving an input command of a user; according to the input command, the tested script data is sent to the automatic driving vehicle data recording system through the data extraction tool, and the automatic driving vehicle data recording system is triggered to operate through the data extraction tool; receiving test result data from the automatic driving vehicle data recording system, and analyzing and judging the test result data; the test result data is data extracted and analyzed by the data extraction tool. According to the system and the method, event record triggering, data extraction, data analysis, result analysis and the like of a whole vehicle level and a part level of the automatic driving vehicle DSSAD can be realized, and the test requirements of DSSAD multi-stage research and development verification can be met.
