Research on car information central control system and its rules

People, vehicles and circumstances are the three key factors of transportation systems, which affect each other much, especially in mixed transport. Offering more information to the driver and helping him observe on all sides so that he can make decisions correctly are of great importance for reducing accidents. In this paper we focus on the rules and process, according to the present traffic regulations, used during steering and overtaking. The results are proposed to implement them in a car information central control system based on CAN.
