The present invention is applicable to the field of intelligent driving, and provides a method and system for dynamic adjustment of intelligent vehicles based on user experience. The system includes: an emotion and physiological monitoring module, an emotion analysis and behavior recognition module, a dynamic driving model construction module, and a driving state adjustment strategy module. A dynamic driving model is constructed by combining the intensity of emotions, non-driving physical behaviors, and the characteristics of the external environment of the vehicle. This model has a powerful simulation capability and can reflect the possible behavioral states of users under current driving conditions. By dynamically simulating the driver's state, the system can predict the driver's reaction in a specific situation, so as to take corresponding safety measures in advance. For example, if the model shows that the driver is prone to emotional fluctuations under complex road conditions, the system can actively adjust the vehicle's driving mode, reduce the speed, or increase monitoring of the environment, which not only prevents potential dangers from occurring, but also improves driving safety and comfort.
