The Implementation of Driver Model Based on the Attention Transfer Process

Abstract

To describe the characteristics of driver's attention changing with driving environment, establish the relation between driver model parameter and driver's attention, seek for mapping relation between driver's behavior and vehicle's running status data, and provide individualized driver simulation model for unmanned car controller or for driver's mental state inversion based on vehicle's running status data, the paper established a driver model based on driver's attention and deduced the relation between attention intensity and continuous driving time according to the process of driver's attention change from concentration to distraction and the distribution characteristics of their durations. The relationship between driver's mental state and manual closed-loop driving model parameters is established according to the transfer rule of attention in the driving course, and it is applied to driver model based on dynamical regulation neural network. Finally the paper researched dynamics evolution characteristics of vehicle running caused by fatigue driving in the environment of double lane change and large curvature, with test result verifying the effectiveness and accuracy of the driver model based on the attention transfer process.
