Abstract

The purpose of the present application is to provide a method or a device for determining a driving strategy based on reinforcement learning and rule fusion. The method comprises: based on the drivingparameter information of a vehicle, determining first driving strategy information of the vehicle through a reinforcement learning algorithm; based on the driving parameter information and the driving rule information of the vehicle, performing rationality detection on the first driving strategy information; and determining target driving strategy information of the vehicle based on the detectionresult of the rationality detection. Compared with the prior art, according to the technical scheme of the present application, the first driving strategy information calculated and determined by thereinforcement learning algorithm is constrained by the rule, so that the method for determining the driving strategy provided by the present application is more intelligent than the existing method for implementing vehicle control by using the rule algorithm, or the method for implementing vehicle control by using the reinforcement learning algorithm, and the rationality and stability of the finally determined driving strategy are improved.
