Problems solved by technology

However, this test method needs to go through millions of kilometers of tests on physical vehicles, which is low in test efficiency and high in cost
Moreover, due to the complex conditions on the road, the operating parameters of the physical vehicle during the test process often cannot correctly reflect the actual operating parameters, resulting in poor reliability of the test results

Description

technical field [0001] Embodiments of the present invention relate to automatic driving technology, and in particular to a simulation test platform, method and storage medium. Background technique [0002] Autonomous driving has gradually become the development trend of the automotive industry. With the increase of autonomous driving levels and rich functions, in order to ensure the safety of autonomous driving vehicles, autonomous driving vehicles must be tested before going online to verify whether the automatic driving vehicles meet the online standards. [0003] The traditional testing method of self-driving vehicles is to let the physical vehicle drive automatically on the road, and use test tools to collect the operating parameters during the automatic driving process of the physical vehicle. However, this testing method requires physical vehicles to be tested for millions of kilometers, and the testing efficiency is low and the cost is high. Moreover, due to the comp...
