Research on safety lane change model of driver assistant system on highway

To solve those traffic accidents during conscious lane change of vehicles on highway under dangerous conditions, a new safety lane change model is established on the basis of the lane departure warning system which Jilin University has developed. This model is studied under a typical scenario on highway, and also considered with the actual driver behavior that most vehicles always accelerate during lane changing process. Simulation software is developed to testify the model performance based on Matlab7.0. The results show that the new lane change model can offer certain technical foundation for actualization of safety lane change system of vehicle assistant driving on highway.
