    Abstract: An autonomous driving method implemented by using an automatic driving model is provided. The autonomous driving model comprises a multimodal encoding layer and a decision control layer. The autonomous driving method includes: obtaining first input information of the multimodal encoding layer; inputting the first input information into the multimodal encoding layer to obtain an implicit representation corresponding to the first input information output by the multimodal encoding layer; and inputting second input information including the implicit representation into the decision control layer to obtain target autonomous driving strategy information output by the decision control layer.
