Traffic signs recognition device and speed limit providing method thereof
First Claim
1. A Traffic Sign Recognition (TSR) device which acquires traffic sign information on a traffic sign positioned on a road through a camera, receives road information from a navigation terminal configured to create and display a driving path of a vehicle and outputs a speed limit of the driving path of the vehicle, comprising:
- an electronic control unit configured to provide a speed limit updated from the navigation terminal, if the acquired traffic sign information does not provide speed limit information but a road attribute contained in the road information is changed or the acquired traffic sign information is indication information indicating a changing of a speed limit, based on the acquired traffic sign information acquired through the camera and the road information being received from the navigation terminal while the vehicle travels along the driving path,wherein the electronic control unitrecognizes the speed limit of the acquired traffic sign information when the vehicle travels on an expressway, anddecides the speed limit updated from the navigation terminal as the speed limit of a driving road, when the vehicle is traveling at a higher speed by a predetermined speed or more than the speed limit within a preset reference distance or traveling at a higher speed by a preset reference speed or more than the speed limit of the acquired traffic sign information.

Abstract
Disclosed herein is a TSR (Traffic Sign Recognition) device which acquires information on a traffic sign positioned on a road through a camera and recognizes and outputs the speed limit of the acquired traffic sign information. The TSR device may include a navigation terminal and an electronic control unit. The navigation terminal may create and display a driving path of a vehicle. The electronic control unit may provide a speed limit updated from the navigation terminal, when a road attribute contained in the road information is changed or the sign information is indication information indicating a speed limit change, based on road information on the driving path and the sign information acquired through the camera, the road information being received from the navigation terminal while the vehicle travels along the driving path.

8. A speed limit providing method of a Traffic Sign Recognition (TSR) device which acquires traffic sign information on a traffic sign positioned on a road through a camera, receives road information from a navigation terminal configured to create and display a driving path of a vehicle and outputs a speed limit of the driving path of the vehicle, comprising:
-
acquiring the traffic sign information on the traffic sign positioned on the road through the camera; and providing a speed limit updated from the navigation terminal, if the acquired traffic sign information does not provide speed limit information but a road attribute contained in the road information is changed or the acquired traffic sign information is indication information indicating a changing of a speed limit, based on the acquired traffic sign information acquired through the camera and the road information, wherein the providing of the updated speed limit comprises recognizing the speed limit of the acquired traffic sign information acquired through the camera when the vehicle travels on an expressway, and deciding the speed limit updated from the navigation terminal as the speed limit of a driving road, when the vehicle is traveling at a higher speed by a predetermined speed or more than the speed limit within a preset reference distance or traveling at a higher speed by a preset reference speed or more than the speed limit of the acquired traffic sign information acquired through the camera. - View Dependent Claims (9, 10, 11, 12)
