1. A vehicle, comprising:
- an image capture unit configured to acquire image information by imaging a forward view of the vehicle;
an imaging device controller configured to determine whether a traffic sign that indicates speed limit information of a road is recognized abnormally based on the acquired image information; and
a navigation controller configured to display either speed limit information of the road stored in a imaging device database or speed limit information of the road stored in a map database in response to determining that the traffic sign is recognized abnormally,wherein the imaging device controller is further configured to detect a cause of the abnormal traffic sign recognition and determine whether to display the speed limit information of the road stored in the imaging device database based on the detected cause.

Abstract
A vehicle and a method of controlling the vehicle are provided. The vehicle includes an image capture unit that is configured to acquire image information by imaging a forward view of the vehicle and an imaging device controller that is configured to determine whether a traffic sign that indicates speed limit information of a road is recognized abnormally based on the acquired image information. A navigation controller is configured to display either speed limit information stored in an imaging device database or speed limit information of the road stored in a map database in response to determining that the traffic sign is recognized abnormally.

9. A vehicle, comprising:
-
an imaging device database in which speed limit information of a road is stored; an imaging device controller configured to determine whether the speed limit information of the road stored in the imaging device database has changed when speed limit information is acquired abnormally from a traffic sign located around the road while driving; and a display device configured to display either the speed limit information stored in the imaging device database or speed limit information stored in a map database based on results of the determination, wherein the imaging device controller is further configured to detect a cause of the abnormal speed limit information acquisition and determine whether the speed limit information stored in the imaging device database has changed based on the detected cause. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of controlling a vehicle, comprising:
-
acquiring, by an imaging device, image information by imaging a forward view of the vehicle; determining, by a controller, whether a traffic sign that indicates speed limit information of a road is recognized abnormally from the acquired image information; and operating, by the controller, a device installed within the vehicle to display either speed limit information stored in a imaging device database or speed limit information stored in a map database in response to determining that the traffic sign is recognized abnormally, wherein the determination of whether the traffic sign is recognized abnormally is performed by detecting a cause of the abnormal traffic sign recognition and determining whether to display the speed limit information stored in the imaging device database based on the detected cause.
