Automated self-control traveling system for expressways and method for controlling the same
First Claim
1. A self-control traveling system for an expressway, comprising:
- a plurality of road signs consecutively installed at left and right sides of the expressway;
an imaging device configured to generate images of the road signs arranged along the expressway;
image processing means for analyzing at least one image inputted from said imaging device, discriminating said road signs and reading sign contents contained in said road signs;
storage means for storing map information of the expressway;
determination means for determining a current position and a road state on the basis of the map information stored in said storage means and the sign contents read by said image processing means; and
control means for controlling steering operation, speed decrement/increment operation and others associated with the self-control traveling operation according to a result of the determination.

Abstract
A self-control traveling system for an expressway and a method for controlling the same is disclosed. A plurality of road signs are consecutively installed at left and right sides of the expressway. An imaging device images the road signs arranged along the expressway. An image processor analyzes at least one image, discriminates the roadside signs and reads sign contents contained in the roadside signs. A navigation database stores map information of the expressway. An artificial intelligence-electronic control unit determines a current position and a road state on the basis of the map information stored in the navigation database and the sign contents read by the image processor. An integrated ECU controls a steering operation, a speed decrement/increment operation and others associated with the self-control traveling operation according to a result of the determination.

7. A method for controlling a self-control traveling system for an expressway, comprising:
-
(a) determining whether at least one image received from an imaging device contains information indicating a starting point for enabling a self-control traveling operation;
(b) determining whether a self-control traveling command is inputted according to a result of the determination at the step (a), switching a driving mode from a manual driving mode to an automatic driving mode, requesting that destination information be inputted, and starting the self-control traveling operation;
(c) searching for corresponding map information associated with the inputted destination information when the self-control traveling operation is started, determining whether a turning point is indicated in the searched map information, and performing the self-control traveling operation according to a result of the determination;
(d) determining whether turning-point information is inputted among input image information during the self-control traveling operation;
(e) controlling an automatic turning operation or determining whether an automobile has arrived at an end point according to a result of the determination at the step (d); and
(f) switching the driving mode from the automatic driving mode to the manual driving mode according to a result of the determination at the step (e), and terminating the self-control traveling operation. - View Dependent Claims (8, 9, 10, 11)

12. A self-control traveling system for a roadway including a plurality of road signs installed along sides of the roadway, the system comprising:
-
an imaging device configured to generate images of the road signs;
an image processor programmed to analyze images received from said imaging device, said analysis including discriminating and reading road sign content;
a memory configured as a database of roadway map information;
a status processor programmed to determine current position and road state based on roadway map information received from said memory and road sign analysis received from said image processor; and
a control processor programmed to effect vehicle self-control based on said current position and road state received from the status processor. - View Dependent Claims (13, 14, 15, 16)
