Vehicle and method for controlling the same
First Claim
1. A vehicle comprising:
- a preceding-vehicle detection unit configured to detect a plurality of other vehicles located in front of the vehicle of a driver and to acquire information about a position of the plurality of other vehicles;
a driver visual line detection unit configured to acquire information about a visual line of the driver and an angle of the visual line with respect to a front direction of the vehicle; and
a control unit configured to choose a target vehicle based on the information about the position of the plurality of other vehicles which is acquired by the preceding-vehicle detection unit and the information about the visual line of the driver which is acquired by the driver visual line detection unit, and configured to control a traveling speed of the vehicle which the driver drives such that an inter-vehicle distance from the target vehicle becomes a preset distance,wherein when the driver respectively looks at first and second vehicles of the plurality of other vehicles, the control unit is configured to compare angles of visual lines corresponding to the first and second vehicles and give different weight values to the first and second vehicles based on a distance from the vehicle when the angles of visual lines are same to each other, andwherein the control unit is configured to choose one of the first and second vehicles as the target vehicle based on the weighted values.

Abstract
A vehicle chooses a target vehicle based on a position of a preceding vehicle and information about a visual line of a driver, both of which are acquired by respective detection units provided in the vehicle, and controls a traveling speed of the vehicle of the driver in relation with the target vehicle. The vehicle includes: a preceding-vehicle detection unit to detect other vehicle located in front of the vehicle of a driver to acquire a position of the other vehicle; a driver visual line detection unit to acquire information about a visual line of the driver; and a control unit to choose a target vehicle based on the information of the other vehicle and the information about the visual line of the driver and control a traveling speed of the vehicle which the driver drives such that an inter-vehicle distance from the target vehicle becomes a preset distance.

12. A method for controlling a vehicle, comprising:
-
detecting a plurality of other vehicles located in front of the vehicle of a driver and acquiring information related to a position of the plurality of other vehicles; acquiring information related to a visual line of the driver and an angle of the visual line with respect to a front direction of the vehicle; choosing a target vehicle based on the acquired information about the position of the plurality of other vehicles and the acquired information about the visual line of the driver; and controlling a traveling speed of the vehicle of the driver such that an inter-vehicle distance from the target vehicle becomes a preset distance, wherein the choosing the target vehicle includes; when the driver respectively looks at first and second vehicles of the plurality of other vehicles, obtaining angles of visual lines corresponding to the first and second vehicles, comparing the obtained angles and giving a weight value to the first and second vehicles based on a distance from the vehicle when the angles of the visual lines are same to each other, and choosing the target vehicle based on the weighted values. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
