Abstract: According to the shortcoming of present single threshold intelligent vehicle collision warning model that it has single response time, a innovative collision warning model was designed based on multi-grade warning rules, which offers a gradual response time for driver, and can increase more react time for the driver to avoid collision in an emergency. Driver′s information perception character in the course of vehicle traveling was analysed, and that offers corresponding theory foundation for the establishment of the following collision warning model. The collision warning model was designed based on multi-grade warning rules, and the design process was discussed in detail. The model is verified using the actual measurement data, and result shows that driver can drive more comfortably in this multi-grade warning model. Meanwhile, it presents good model foundation reference for intelligent collision warning system in future. -
