Abstract

A system and method for alerting drowsy driving are provided. The system includes a d controller configured to analyze a driving pattern of a vehicle to detect a dangerous driving pattern. In addition, the controller is configured to analyze a face image of a driver to detect an eye pattern maintained for a predetermined period of time or longer. Further, the controller is configured to determine that the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and the dangerous driving pattern are simultaneously detected.

Claims

1. A system for alerting a drowsy drive, comprising:

a memory configured to store program instructions; and

a controller configured to execute the program instructions, the program instructions when executed configured to;

analyze a driving pattern of a vehicle;

detect a dangerous driving pattern;

analyze a face image of a driver;

detect in the face image an eye pattern for a predetermined period of time or longer; and

determine the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and the dangerous driving pattern are simultaneously detected.

2. The system according to claim 1, wherein the program instructions when executed are further configured to output at least one of selected from the group consisting of:

an alarm sound, an alarm phrase, and an alarm vibration.

3. The system according to claim 1, wherein the dangerous driving pattern includes at least one selected from the group consisting of a zigzag pattern, an over-steering pattern, an under-steering pattern, a lane violation pattern, and a lane following error pattern.

4. The system according to claim 1, wherein the program instructions when executed are further configured to

detect an eye open or close of the driver to detect the eye closing for the predetermined period of time or longer,

wherein the eye close includes a half-closed eye of the driver.

5. The system according to claim 1, wherein the program instructions when executed are further configured to:

determine that the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and an under-steering pattern are detected simultaneously.

6. The system according to claim 1, wherein the program instructions when executed are further configured to:

determine the driver is driving while drowsy when an over-steering pattern is detected after the driver'"'"'s eyes open after the eye closing for the predetermined period time or longer.

7. The system according to claim 1, wherein the program instructions when executed are further configured to:

determine the driver is driving while drowsy when a substantially high transverse velocity is maintained while the eye closing for the predetermined period of time or longer is detected.

8. A method for alerting a drowsy drive, the method comprising:

simultaneously analyzing, by a controller, a driving pattern and an eye closing pattern, from a face image, for a predetermined period of time or longer; and

determining, by the controller, whether a driver is driving while drowsy when a dangerous driving pattern and the eye closing pattern for the predetermined period of time or longer is detected.

9. The method according to claim 8, further comprising outputting, by the controller, at least one selected from the group consisting of:

an alarm phrase, an alarm sound, and an alarm vibration as a drowsy drive alarm when it is determined that the driver is driving while drowsy.

10. The method according to claim 9, wherein the determining of whether the driver is driving while drowsy includes:

determining, by the controller, the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and an under-steering pattern are detected simultaneously.

11. The method according to claim 9, wherein the determining of whether the driver is driving while drowsy includes:

determining, by the controller, the driver is driving while drowsy when over-steering pattern is detected after the driver'"'"'s eyes open after the eye closing for the predetermined period time or longer from a face image.

12. The method according to claim 9, wherein the determining of whether the driver is driving while drowsy includes:

determining, by the controller, the driver is driving while drowsy when a substantially high transverse velocity is maintained while the eye closing for the predetermined period of time or longer is detected.

13. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable comprising:

program instructions that analyze a driving pattern of a vehicle;

program instructions that detect a dangerous driving pattern;

program instructions that analyze a face image of a driver;

program instructions that detect in the face image an eye pattern maintained for a predetermined period of time or longer; and

program instructions that determine the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and the dangerous driving pattern are simultaneously detected

14. The non-transitory computer readable medium of claim 13, further comprising program instructions that output at least one of selected from the group consisting of:

an alarm sound, an alarm phrase, and an alarm vibration.

15. The non-transitory computer readable medium of claim 13, wherein the dangerous driving pattern includes at least one selected from the group consisting of a zigzag pattern, an over-steering pattern, an under-steering pattern, a lane violation pattern, and a lane following error pattern.

16. The non-transitory computer readable medium of claim 13, the program instructions further comprising:

program instructions that detect an eye open or close of the driver to detect the eye closing for the predetermined period of time or longer,

wherein the eye close includes a half-closed eye of the driver.

17. The non-transitory computer readable medium of claim 13, the program instructions further comprising:

program instructions that determine that the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and an under-steering pattern are detected simultaneously.

18. The non-transitory computer readable medium of claim 13, the program instructions further comprising:

program instructions that determine the driver is driving while drowsy when an over-steering pattern is detected after the driver'"'"'s eyes open after the eye closing for the predetermined period time or longer.

19. The non-transitory computer readable medium of claim 13, the program instructions further comprising:

program instructions that determine the driver is driving while drowsy when a substantially high transverse velocity is maintained while the eye closing for the predetermined period of time or longer is detected.
