Abstract

Disclosed are a driving guide system and method. The driving guide system includes an input unit configured to receive signal information from a signal controller, a memory in which a driving guide program using the signal information is embedded, and a processor configured to execute the program. When it is not possible to recognize a traffic light using a camera, the processor determines a driving behavior using the signal information and then performs autonomous driving according to the driving behavior or provides a notification to a driver.

First claim

What is claimed is:

1 . A driving guide system, comprising:
a processor; a computer-readable medium in communication with the processor and storing instructions that, when executed by the processor, cause the processor to control the driving guide system to perform:
detecting that a traffic light at an intersection captured by a camera of a host vehicle is not recognizable; and
in response to detecting that the captured traffic light is not recognizable, receiving, from a traffic signal controller via a communication network, traffic signal information;
determining, based on the received traffic signal information, a driving behavior for the host vehicle; and
autonomously driving the host vehicle based on the determined driving behavior.

2 . The driving guide system of claim 1 , wherein, when it is determined that the captured traffic light is not recognizable, the instructions, when executed by the processor, further cause the processor to control the driving guide system to perform a vehicle-to-infrastructure (V2I) communication with the traffic signal controller.

3 . The driving guide system of claim 1 , wherein the received traffic signal information includes at least one of a currently turned-on traffic signal, a remaining turning-on duration of the currently turned-on traffic signal, and a remaining waiting time until a next traffic signal turning-on time.

4 . The driving guide system of claim 1 , wherein the received traffic signal information includes traffic situation information indicating a traffic situation at the intersection.

5 . The driving guide system of claim 4 , wherein the instructions, when executed by the processor, further cause the processor to control the driving guide system to perform determining the driving behavior further based on driving information of the host vehicle and the traffic situation information.

6 . The driving guide system of claim 5 , wherein the instructions, when executed by the processor, further cause the processor to control the driving guide system to perform determining the driving behavior further based on preset driver satisfaction information.

7 . The driving guide system of claim 5 , wherein the traffic situation information including at least one of a number of preceding vehicles having the same driving path as that of the host vehicle, behaviors of the preceding vehicles, and an estimated intersection passing time at which the host vehicle is estimated to pass through the intersection.

8 . The driving guide system of claim 5 , wherein the intersection is a nearby intersection that is not a current intersection.

9 . A method for providing a driving guide for a host vehicle, the method comprising:
detecting that a traffic light of an intersection captured by a camera of the host vehicle is not recognizable; and in response to detecting that the captured traffic light is not recognizable, performing a vehicle-to-infrastructure (V2I) communication with a traffic signal controller to receive traffic signal information; determining, based on the received traffic signal information, a driving behavior for the host vehicle; and autonomously driving the host vehicle based on the determined driving behavior.

10 . The method of claim 9 , wherein, the traffic signal information includes at least one of a currently turned-on traffic signal, a remaining turning-on duration of the currently turned-on traffic signal, and a remaining waiting time until a next traffic signal turning-on time.

11 . The method of claim 9 , further comprising providing, via a human-machine interface (HMI) of the host vehicle, information related to the driving behavior.

12 . The method of claim 9 , wherein the traffic signal information includes traffic situation information which includes at least one of a number of preceding vehicles having the same driving path as that of the host vehicle, behaviors of the preceding vehicles, and an estimated intersection passing time at which the host vehicle is estimated to pass through the intersection.

13 . The method of claim 12 , wherein the driving behavior is determined further based on driving information of the host vehicle, the traffic situation information, and preset driver satisfaction information.

14 . The method of claim 9 , wherein the intersection is a nearby intersection that is not a current intersection.
