Research of driver optimal preview acceleration integrated decision model

Research of driver model is not only important to study of vehicle handling and stability, but also turn to be a key technology to the study of vehicle intelligent assistant driving systems and intelligent vehicle. Both driver's behavior and characters of vehicle's move are to be analyzed in this paper, make the decision of lateral and longitudinal acceleration for its changing scale and bring out its increment network, simple method with transform of reference frame used to preview vehicle future course, integrated decision of vehicle preview course is made by the index of efficiency with index of safety and handling. Simulation on typical road verified the rationality and validity of the model.
