In order to detect the risky driving status of heavy duty vehicle,the double-layer hidden Markov model( HMM) is used for the rollover warning system of heavy duty vehicle,which can identify the driving status dynamically. The data is collected during the typical driving conditions,and the T-G test method is used to delete the abnormal data. The driving limit value of vehicle status is set based on Kmeans algorithm. Then finally Baum-Welch algorithm is used to optimize the proposed double-layer HMM,and the optimized HMM is used to identify the driving status in real-time. The identification results show that the proposed model can identify the driving status under every single driving condition as well as under the multiple driving conditions accurately and effectively. At the same time this model has a good real-time capacity.
