The invention provides an automatic driving test system and method based on a digital twin cloud control platform, and the method comprises the steps: generating a high-fidelity virtual scene needing to be developed and tested through simulation software, and building a plurality of virtual sensor models in the simulation software; target object information detected by the virtual sensor is injected into an automatic driving controller on a real vehicle through a bus, information fusion and control decision making are carried out, and the controller sends acceleration, braking and steering instructions after decision making to a real vehicle actuator. And the real vehicle feeds back the whole vehicle motion state information on the vehicle bus to the virtual scene to complete vehicle position synchronization, so that closed-loop real-time test verification of the whole system is realized, and scene-related twinning effects are displayed in real time through the digital twinning cloud control platform.
