The invention discloses an SRL-based intelligent networked automobile function degradation decision-making method and system. The method comprises the following steps: step 1, acquiring environment information and monitoring a trigger event; 2, grading the system risk assessment indexes of the trigger event monitored in the step 1, determining a corresponding automobile safety integrity grade according to an actual driving mode, and obtaining the system risk of the automobile; 3, according to the environment information collected in the step 1, integrating the risk fields of the static obstacles, the dynamic obstacles and the road boundaries, and utilizing a driving risk field model to obtain the driving risk of the vehicle; 4, describing the function degradation decision-making process of the intelligent networked automobile through a CMDP model to obtain an optimal function degradation strategy; wherein the state space S and the cost function of the CMDP model both comprise the system risk in the step 2 and the driving risk in the step 3. According to the method, efficient, safe and stable function degradation decision making of the intelligent network connection automobile in a complex and changeable scene can be achieved.
