Classification: CPC B  H  G | IPC B  G  H

Claim 8:
9. A wireless terminal location information-based accident prevention method comprising:
receiving GPS information of a wireless terminal located within a predetermined distance from a host vehicle;
detecting an object corresponding to the GPS information of the wireless terminal by a sensor provided in the host vehicle;
determining a first time-to-collision with the detected object based on a change of the GPS information;
determining a second time-to-collision with the detected object based on motion information of the detected object; and
controlling the host vehicle to avoid according to a predetermined criterion based on the first time-to-collision and the second time-to-collision,
wherein the controlling the host vehicle comprises,
when the detected object is obscured by an obstacle, determining whether the speed of the detected object is changed from the speed of the detected object detected by the sensor 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, determining the second time-to-collision based on the speed of the detected object before being obscured, and controlling 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, controlling the host vehicle to prevent a collision with the detected object based on the first time-to-collision.
