A safety tips system for large trucks for lane change

For the problem that blind spot of large trucks is relatively big and potentially rear-end in lane change and other issues. This paper proposed a large truck lane change security tips system. The system uses millimeter-wave radar to detect the positional relationship between the truck and the vehicle at rear of truck. Determine the level of security of vehicles change lanes with different values of TTC. The system can significantly reduce the incidence of truck rear-end accident in the process of lane changing.
