HYUNDAI MOTOR CO LTD [KR]; KIA MOTORS CORP [KR]
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.
[0007] The present disclosure provides a vehicle capable of informing a driver of the risk of collision at an optimal time by controlling a collision warning time in consideration of the driver's gaze, field of view and visibility of the forward object, and a method of controlling the vehicle. Accordingly, the satisfaction of the driver, the reliability of the system, and the accident prevention effect can be enhanced.
[0008] Additional aspects of the disclosure will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the disclosure.
[0009] In accordance with an aspect of the present disclosure, a vehicle includes a distance sensor configured to collect data of an object; a camera configured to collect image data; a driver recognition sensor configured to collect driver's facial data; and a controller configured to analyze driver's gaze and field of view using the driver's facial data, analyze visibility of the object using the image data, and calculate 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 configured to inform the driver of the risk of collision at the collision warning time under the control of the controller.
[0010] The controller may be configured to calculate a driver's attention distribution function by analyzing the driver's gaze and the field of view, calculate a visibility index by analyzing the visibility of the object, and calculate a recognition index using the driver's attention distribution function and the visibility index.
