The invention relates to a driving control method based on self-supervised imitation learning, and belongs to the technical field of automatic driving reinforcement learning. Comprises: generating an automatic driving task data set; determining a t moment potential representation of an anchor node in the observation image and a potential representation of a sample related to the anchor node; integrating the potential representation z < = t smaller than the t moment in the potential space, and generating the potential representation ct of the context at the t moment; retaining effective information between the observation image st + k at the t + k moment and the ct by using a density comparator; and after different automatic driving scene observation images pass through a trained encoder, calculating a cost function, and after the cost function is updated, transmitting the updated cost function into a simulation learning target formula to update a strategy network. According to the method, dimension disasters in a high-dimensional data learning strategy can be relieved through dimension reduction mapping, high-density information with higher correlation with tasks in image observation data is extracted, and the sampling efficiency of model samples is improved.
