BLIND SPOT WARNING SYSTEM AND METHOD
First Claim
1. A blind spot warning system for warning whether a target vehicle is located in a blind spot formed at a posterolateral area of a host vehicle, comprising;
- a line-to-line space-generating unit generating line-to-line space data with respect to a lane width, which changes when the host vehicle is driven, in real time;
at least one distance-measuring unit measuring a distance between the host vehicle and a target vehicle located in a side zone or a rear zone of the host vehicle;
an input unit receiving the line-to-line space data from the line-to-line space-generating unit and receiving the distance measurement information from the distance-measuring unit;
a comparison unit comparing the target vehicle distance data based on the distance measurement information transferred from the distance-measuring unit with the line-to-line space data to decide whether the target vehicle is located within the threshold vehicle-to-vehicle distance determined based on the line-to-line space data; and
a warning output unit for outputting a warning if the target vehicle is located within the threshold vehicle-to-vehicle distance in the blind spot formed at the posterolateral area of the host vehicle.

Abstract
The present invention relates to a blind spot warning system and method for sensing a vehicle in a blind spot of a vehicle and warning thereof in advance, the blind spot warning system comprising a line-to-line space-generating unit that generates, in real time, line-to-line space data, which changes when the host vehicle is driven; a distance-measuring unit, which measures the distance between the host vehicle and a target vehicle located in a blind spot of the host vehicle; an input unit, which receives the line-to-line space data and the distance measurement information; a comparison unit, which compares the target vehicle distance data with the line-to-line space data to decide whether the target vehicle is located within the threshold vehicle-to-vehicle distance; and a warning output unit for outputting a warning if the target vehicle is located within the threshold vehicle-to-vehicle distance in the blind spot.

6. A blind spot warning method for warning whether a target vehicle is located in a blind spot formed at a posterolateral area of a host vehicle in a blind spot warning system mounted in the host vehicle, comprising the steps of;
-
generating line-to-line space data with respect to a lane width of a road, which changes when the host vehicle is driven, through a line-to-line space-generating unit in real time; measuring a distance between the host vehicle and a target vehicle which is located in a side zone or a rear zone of the host vehicle, during driving of the host vehicle; receiving the line-to-line space data from the line-to-line space-generating unit and receiving the distance measurement information from a distance-measuring unit; generating target vehicle distance data on a basis of the distance measurement information from a distance-measuring unit; comparing the target vehicle distance data with the line-to-line space data to decide whether the target vehicle is located within the threshold vehicle-to-vehicle distance, which is determined based on the line-to-line space data; and outputting a warning if the target vehicle is located within the threshold vehicle-to-vehicle distance in the blind spot formed at the posterolateral area of the host vehicle. - View Dependent Claims (7, 8, 9, 10)
