Apparatus, method, and vehicle for providing braking level of forward vehicle

A method for providing a braking level of a forward vehicle in an apparatus for providing the braking level of the forward vehicle, comprising a brake lamp position recognizing device, a braking determining device, a braking level determining device and braking level image providing device, the method comprising:

• recognizing, by the brake lamp position recognizing device, positions of brake lamps of the forward vehicle based on an image of the forward vehicle and a relative acceleration of the forward vehicle;
• determining, by the braking determining device, whether or not braking of the forward vehicle is performed based on a brake lamp image extracted from the image of the forward vehicle when the positions of the brake lamps are recognized;
• determining, by the braking level determining device, the braking level of the forward vehicle based on the relative acceleration of the forward vehicle upon determining that braking of the forward vehicle is performed;
• and
• providing, by the braking level image providing device, the determined braking level of the forward vehicle through an image when the braking level is determined.

A vehicle comprising:

• a camera configured to acquire an image of a forward vehicle;
• a radar configured to acquire a relative acceleration of the forward vehicle;
• a display configured to display a braking level image of the forward vehicle;
• and
• an apparatus for providing a braking level of the forward vehicle, configured to determine the braking level of the forward vehicle based on the image of the forward vehicle and the relative acceleration of the forward vehicle and to provide the braking level through an image,
• wherein the apparatus recognizes positions of brake lamps of the forward vehicle based on the image of the forward vehicle and the relative acceleration of the forward vehicle, determines whether braking of the forward vehicle is performed based on a brake lamp image extracted from the image of the forward vehicle, determines the braking level of the forward vehicle based on the relative acceleration of the forward vehicle, generates the braking level image based on the determined braking level of the forward vehicle, and provides the braking level image to the display.
