Automatic Driving Decision Making Method, System And Device And Computer Storage Medium

An automatic driving method includes following steps: S 101 : acquiring real-time traffic environment information in a travel process of an autonomous vehicle at a current moment; S 102 : mapping the real-time traffic environment information based on a preset mapping relationship to obtain mapped traffic environment information; S 103 : adjusting a target deep reinforcement learning model based on a pre-stored existing deep reinforcement learning model and the mapped traffic environment information; and S 104 : judging whether automatic driving is finished, and in response to the automatic driving is not finished, returning to perform the step of acquiring the real-time traffic environment information in the travel process of the autonomous vehicle at the current moment. An automatic driving system, an automatic driving device and a computer medium storing the automatic driving method are further provided.
