Piloted driving vehicle training method based on virtual environment and depth double-Q network

Abstract

The invention relates to a piloted driving vehicle training method based on a virtual environment and a depth double-Q network. The method comprises: constructing a vehicle racing track virtual environment based on Unity; establishing a communication connection between the Unity and a piloted driving vehicle model under a Websocket protocol; establishing a Markov model that represents a vehicle piloted driving process, transforming a depth double-Q network algorithm to train a piloted driving model; configuring an entity vehicle soft hardware environment, migrating a trained vehicle piloted driving model; and testing an entity vehicle in a real racing track to train a piloted driving operation of the model. According to the method, a virtual environment is used for training a model, to implement robustness of a piloted driving training algorithm model on a complex environment and road condition. According to the method, by means of the depth double-Q network algorithm, a problem of high train complexity caused by a large assessment value of a Q value is avoided, so that a training process is simple and fast. The method has advantages of strong robustness, a fast speed, low costs and the like. The method can be applied to training and learning of unpiloted operation in fields such as intelligent traffic, aerospace, robots and the like.
