Abstract

A vehicle is provided and configured to allow a driver to recognize a degree of proximity of another vehicle by turning on a warning light differentially based on a degree of proximity of the other vehicle driving in a blind spot. The vehicle includes a rear lateral side detection unit that is configured to detect a rear lateral side including a blind spot and a side mirror including a mirror. A first indicator is disposed in the mirror and is configured to be turned on when a blind spot detection function is activated and a second indicator includes a plurality of indicators and is configured such that the number of a turned-on indicator is increased in a predetermined direction as a distance between the other vehicle, which is approaching in a blind spot, and a subject vehicle decreases, according to a detection result of the rear lateral side detection unit.

First claim

What is claimed is:

1. A subject vehicle, comprising:
a rear lateral side detection unit configured to detect a rear lateral side including a blind spot, the rear lateral side detection unit including a rear camera, a side camera, and a blind spot detection radar;
a controller configured to calculate a distance between a vehicle detected in the blind spot and the subject vehicle and a time to collision of the detected vehicle with the subject vehicle in a driving lane of the subject vehicle based on a detection result of the rear lateral side detection unit, and to control an indicator of the side mirror based on information related to the calculation; and
a side mirror including:
a mirror;
a first indicator disposed in the mirror and configured to be turned on when a blind spot detection function is activated; and
a second indicator having a plurality of indicators and configured such that the number of a turned-on indicator is increased in a predetermined direction as a distance between another vehicle, which is approaching in a blind spot to the subject vehicle decreases, based on a detection result of the rear lateral side detection unit, the number of the turned-on indicator previously stored based on a variation of the distance between the approaching other vehicle and the subject vehicle,
wherein the side mirror includes a third indicator having a plurality of indicators disposed in an edge of a lower lateral side of the side mirror, and
wherein the third indicator is configured such that the number of a turned-on indicator is increased in a predetermined direction, as a time to collision with the other vehicle, which is approaching in the driving lane of the subject vehicle while being moved from a second lane to a driving lane of the vehicle to a next lane to a driving lane of the vehicle, decreases based on a detection result of the rear lateral side detection unit, the number of the turned-on indicator in the third indicator previously stored based on a variation of the time to collision with the approaching other vehicle and the subject vehicle.

2. The vehicle of claim 1 wherein the second indicator is disposed in an edge of an upper portion of the mirror.

3. The vehicle of claim 1 wherein, the second indicator is arranged to correspond to the shape of the upper portion of the mirror.

4. The vehicle of claim 1 wherein, the first indicator and the second indicator are configured to emit each color that is different from each other.

5. The vehicle of claim 1 , further comprising:
a controller configured to determine a location of the other vehicle driven in the blind spot based on a detection result of the rear lateral side detection unit, and configured to determine the number of a turned-on second indicator and a turning-on direction of the second indicator.

6. The vehicle of claim 1 further comprising:
a controller configured to calculate the time to collision with the other vehicle, which is approaching in the rear lateral side of the subject vehicle while being moved from the second lane to the driving lane of the vehicle to a next lane to the driving lane of the vehicle according to the detection result of the rear lateral side detection unit, and configured to determine the number of a turned-on third indicator and a turning-on direction of the third indicator, based on the calculated time to collision.

7. The vehicle of claim 1 wherein, the side mirror further comprises a fourth indicator having a plurality of indicators disposed in an edge of a lower portion of the side mirror.

8. The vehicle of claim 7 wherein, the fourth indicator is configured such that the number of a turned-on indicator is increased in a predetermined direction as the time to collision with the other vehicle, which is approaching from a next lane to the driving lane of the subject vehicle to the rear lateral side of the vehicle, decreases, based on a detection result of the rear lateral side detection unit.

9. The vehicle of claim 7 further comprising:
a controller configured to calculate the time to collision with the other vehicle, which is approaching from a next lane to the driving lane of the subject vehicle to the rear lateral side of the vehicle based on the detection result of the rear lateral side detection unit, and configured to determine the number of a turned-on fourth indicator and a turning-on direction of the fourth indicator, based on the calculated time to collision.

10. A control method of a subject vehicle, comprising:
turning on, by a controller, a first indicator of a side mirror when a blind spot detection function is activated;
turning on, by the controller, a second indicator of the side mirror when a rear lateral side detection unit detects another vehicle, which is approaching the subject vehicle in a blind spot;
increasing, by the controller, the number of a turned-on second indicator in a predetermined direction as a distance between the other vehicle and the subject vehicle decreases, based on a detection result of the a rear lateral side detection unit, the number of turned-on second indicator previously stored based on a variation of the distance between the approaching other vehicle and the subject vehicle;
turning on, by the controller, a third indicator of the side mirror when the rear lateral side detection unit detects the other vehicle, which is approaching in a driving lane of the subject vehicle while being moved from a second lane to the driving lane of the subject vehicle to a next lane to the driving lane of the subject vehicle;
calculating, by the controller, a time to collision with the other vehicle, which is approaching in the driving lane of the subject vehicle, according to a detection results of the rear lateral side detection unit; and
increasing, by the controller, the number of a turn-on third indicator in a predetermined direction as the calculated time to collision decreases, the number of the turned-on third indicator previously stored based on a variation of the time to collision of the approaching other vehicle and the subject vehicle,
wherein the rear lateral side detection unit includes a rear camera, a side camera, and a blind spot detection radar to detect the blind spot.

11. The control method of claim 10 wherein, the increasing of e number of a turned-on second indicator in a predetermined direction, includes:
determining, by the controller, a location of the other vehicle driven in the blind spot based on a detection result of the rear lateral side detection unit; and
determining, by the controller, the number of the turned-on second indicator and a turning-on direction of the second indicator, based on a degree of proximity to the subject vehicle in the determined location.

12. The control method of claim 10 , further comprising:
turning on, by the controller, a fourth indicator of the side mirror when the rear lateral side detection unit detects the other vehicle, which is approaching from a next lane to the driving lane of the subject vehicle to the rear lateral side of the subject vehicle;
calculating, by the controller, the time to collision of the other vehicle, which is approaching in the rear lateral side of the subject vehicle, according to a detection result of rear lateral side detection unit; and

increasing, by the controller, the number of a turned-on fourth indicator in a predetermined direction, as the calculated time to collision decreases.
