Self-evolution and decision management method, device and system of automatic driving model

The embodiment of the invention discloses a self-evolution and decision management method, device and system of an automatic driving model. The method comprises the following steps: acquiring driving behaviors determined by a user and a current automatic driving model for the same driving task; generating a driving behavior loss function according to difference information between the driving behavior determined by the user and a driving behavior determined by a current automatic driving model; according to the driving behavior loss function, updating a loss function of a current automatic driving model to obtain an updated loss function of the automatic driving model; and iterating the current automatic driving model until convergence by using the loss function of the updated automatic driving model to obtain the updated automatic driving model, thereby obtaining the automatic driving model of which the driving style difference with the user is further reduced so as to be closer to the personalized driving s
