Abstract
A driving lane detection device of the present disclosure includes: an object detector, a vehicle detector, and a driving lane detector. The object detector generates object data relating to a distance and direction from the vehicle to an object and a movement direction of the object based on one or more reflection waves that are a radar signal transmitted by a radar device and reflected by the one or more object. The vehicle detector detects each object as at least one of a parallel-running vehicle running in a same direction as the vehicle or an oncoming vehicle running in an opposite direction to the vehicle, based on the object data. The driving lane detector detects a driving lane based on the distance and direction from the vehicle to at least one of the detected parallel-running and the detected oncoming vehicles and lane information on at least one of lane widths and a number of lanes of a road on which the vehicle is running.
