Claim 0:
1. A wireless terminal location information-based accident prevention device comprising:
a receiver configured to receive GPS information of a wireless terminal located within a predetermined distance from a host vehicle;
a sensor unit configured to detect an object corresponding to the GPS information of the wireless terminal; and
a controller configuring to
determine a first time-to-collision with the detected object based on a change of the GPS information,
determine a second time-to-collision with the detected object based on motion information of the detected object, and
control the host vehicle to prevent a collision with the detected object according to a predetermined criterion based on the first time-to-collision and the second time-to-collision,

wherein, when the detected object is obscured by an obstacle, the controller is configured to determine whether the speed of the detected object is changed from the speed of the detected object before being obscured based on the change of the GPS information of the detected object,
if the speed of the detected object is not changed, determine the second time-to-collision based on the speed of the detected object detected by the sensor unit before being obscured, and control the host vehicle to prevent a collision with the detected object based on the first time-to-collision and the second time-to-collision, and
if the speed of the detected object is changed, control the host vehicle to prevent a collision with the detected object based on the first time-to-collision.
