Abstract
Disclosed is an obstacle detection system of a vehicle. The obstacle detection system includes a driving information unit configured to calculate driving position information of the vehicle, a determiner configured to anticipate whether or not the vehicle will enter a joining point where the vehicle meets a target road to be joined based on the driving position information calculated by the driving information unit, a sensing unit configured to sense obstacles located beside the vehicle, and a controller configured to change a sensing range of the sensing unit so as to detect an obstacle moving on the target road to be joined, when the determiner anticipates that the vehicle will enter the joining point.

An obstacle detection system of a vehicle, the obstacle detection system comprising:
- a driving information unit configured to calculate driving position information of the vehicle and a lane width of a target road to be joined;
- a determiner configured to anticipate whether the vehicle will enter a joining point where the vehicle meets the target road to be joined based on the driving position information;
- a sensing unit configured to sense obstacles located beside the vehicle;
- and
- a controller configured to change a sensing range of the sensing unit to position the sensing range on the target road and detect an obstacle moving on the target road to be joined, based on that the determiner anticipates that the vehicle will enter the joining point and to extend the sensing range based on the lane width of the target road to be joined,
- wherein the driving information unit is further configured to calculate an angle of entry between a driving road of the vehicle and the target road to be joined based on information about the driving road of the vehicle and information about the target road to be joined, calculated by the driving information unit,
- wherein the controller is further configured to rotate the sensing range of the sensing unit based on the angle of entry between the driving road of the vehicle and the target road to be joined, calculated by the driving information unit so that the sensing range is to be located on the target road,
- wherein the determiner is further configured to calculate a distance from a driving position of the vehicle to the joining point based on the driving position information and the information about the driving road of the vehicle calculated by the driving information unit,
- wherein the controller is further configured to extend the sensing range of the sensing unit based on the distance from the driving position of the vehicle to the joining point, calculated by the determiner,
- wherein the controller is further configured to extend a lateral width of the sensing range based on the lane width of the target road to be joined, and
- wherein based on the determiner determining that the vehicle will enter the joining point. the controller is further configured to control the sensing unit to longitudinally expand the sensing range of the sensing unit with respect to the target road to be joined.
