Abstract
A warning system for detecting approaching vehicle and method thereof are provided. The system includes a detection unit detecting a relative distance with respect to the approaching vehicle and a driving path of the approaching vehicle; a storage unit storing a warning information; and a processing unit receiving the detection signal to acquire the current time to collision and the current driving path. When the time to collision is equal to or shorter than the predetermined time to collision, and the driving path falls in the warning area, and the driving path fulfills the confirmation condition, the processing unit sends a warning signal. Therefore, a potentially dangerous approaching vehicle is accurately judged, and the warning is correctly sent.
