Emergency Obstacle Avoidance Control Method Based on Driver Steering Intention Recognition for Steer-By-Wire Vehicle

摘要

This paper proposes an emergency obstacle avoidance control method based on driver steering intention recognition for steer-by-wire vehicle in order to solve the problem that the response rate and stability time are unsatisfactory. The paper focuses on the method to recognize driver steering intention, and builds a driver steering behavior model by using the multidimensional Gauss HMM theory, optimizes the model by using the Baum-Welch algorithm and conducts real-time verification on steering intention recognition by means of LabVIEW and driving simulator. The results indicate that the driver steering intention recognition method has higher recognition accuracy and can help to realize emergency obstacle avoidance control effectively for steer-by-wire vehicle.
