摘　　要：为研究高负荷驾驶任务下驾驶员注意力状态转移规律,应用更新过程理论构建了短时段注意力状态概率模型,并给出了近似求解方法.对于长时间连续驾驶,该模型在状态转移点处难以满足齐次性特征要求,可用时段分割法处理.用实际数据对模型进行了仿真实验.结果表明,模型整体误差为2.83%.To study the shifting progress of driver＇ s attention under high driving load, a probability model for driver＇ s attention state during a short period and a approximate solution algorithm were presented based on the Markov process theory. This model is not directly applicable to a long period because it does not meet the homogeneous requirement at driving state transition points, This problem could be solved by cutting the long period into small fractions. Practical data were used for simulation, and the result shows that the overall error of the model was 2.83%.
