Interactive Decision Modeling of Intelligent Vehicle Driving Authority Based on Fuzzy Cognitive Map
A driving authority interaction decision model based on fuzzy cognitive map(FCM)was proposed to address the dynamic transition from autonomous driving to driver takeover in human-machine co-driving scenarios.Firstly,dynamic risk factors influencing driving risks for both the vehicle and the driver were separately analyzed.Relevant influencing indicators such as vehicle spacing,ac-celeration,steering wheel entropy,driver eye movement information,and electroencephalogram(EEG)signals were selected to con-struct FCM-based models for dynamic vehicle risk and driver risk.Subsequently,these models were integrated with environmental fac-tors,vehicle conditions,and driver proficiency to establish an FCM-based driver interaction decision-making model.To reduce reliance on expert knowledge,the model was optimized using a real coded genetic algorithm(RCGA)based on real number encoding,thereby enhancing the accuracy of the model's decision-making.The simulation results indicate that the model,after optimization using RCGA,achieves an adaptation fitness value of 0.979.This suggests that the model is capable of effectively addressing dynamic and complex driving environments.
