Vehicle with driver warning system and method of control
First Claim
1. A vehicle comprising:
- a distance sensor configured to collect data of an object;
a camera configured to collect image data;
a driver recognition sensor configured to collect facial data of a driver; and
a controller configured to analyze a gaze of the driver and a field of view using the facial data, to analyze visibility of the object using the image data, and to calculate a collision warning time based on a result of analyzing the gaze and the field of view and the visibility of the object,wherein the controller is configured to;
control at least one of a warning light, an audio system or an audio video navigation (AVN) system to inform the driver of a risk of collision at the collision warning time,calculate an attention distribution function of the driver by analyzing the gaze and the field of view,calculate a visibility index by analyzing the visibility of the object,calculate a recognition index using the attention distribution function and the visibility index, andcalculate the visibility index of the object by extracting a color coordinate value of the object and a color coordinate value of a surrounding environment of the object from the image data and subtracting a sum of the color coordinate value of the object and the color coordinate value of the surrounding environment of the object from a maximum color coordinate value.

Abstract
A vehicle, which adjusts a collision warning time based on driver'"'"'s field of view and visibility of the object, is provided. The vehicle includes: a distance sensor that collects data of an object, a camera that collects image data, a driver recognition sensor that collects driver'"'"'s facial data, and a controller that analyzes driver'"'"'s gaze and field of view using the driver'"'"'s facial data, analyzes visibility of the object using the image data, and calculates a collision warning time based on a result of analyzing the driver'"'"'s gaze and field of view and the visibility of the object, and an alarm device that informs the driver of the risk of collision at the collision warning time under the control of the controller.

8. A control method of a vehicle, comprising:
-
collecting data of an object, image data, and facial data of a driver; analyzing, by a controller, a gaze of the driver, and a field of view using the facial data of the driver; analyzing, by the controller, visibility of the object using the image data; calculating, by the controller, a collision warning time based on a result of analyzing the gaze, the field of view and the visibility of the object; informing, by an alarm device, the driver of a risk of collision at the collision warning time, wherein; analyzing the gaze and the field of view further comprises calculating, by the controller, an attention distribution function of the driver, and analyzing the visibility of the object using the image data comprises calculating, by the controller, a visibility index of the object; and calculating, by the controller, a recognition index using the attention distribution function of the driver and the visibility index of the object, wherein; calculating the visibility index of the object comprises extracting, by the controller, a color coordinate value of the object and a color coordinate value of a surrounding environment of the object from the image data, and the visibility index is calculated by subtracting a sum of the color coordinate value of the object and the color coordinate value of the surrounding environment of the object from a maximum color coordinate value. - View Dependent Claims (9, 10, 11, 12, 13, 14)
