Abstract：The Digital Twin (DT) provides virtual representations of systems along their lifecycle, and should be used in autonomous driving test. In this paper, a method of using DT to carry out networked couplet autonomous driving test in a finite environment is proposed: in the simulation test environment of automatic driving, the test of real automatic driving vehicles under the virtual complex road scene can be realized by using the DT mapping. The experimental results show that this method can effectively support the development of the autonomous driving test.
