System and method for determining drowsy state of driver
First Claim
1. A system for determining a drowsy state of a driver, the system comprising:
- a heartbeat measurement module configured to detect a heartbeat rate of the driver and output a heartbeat signal corresponding to the detected heartbeat rate;
a vehicle signal measurement module configured to measure a driving state of a vehicle being driven by the driver and output a vehicle signal corresponding to the measured driving state;
a drowsy pattern detection module configured to determine whether a driver has fallen asleep while driving based on the heartbeat signal and the vehicle signal and output a warning signal as a drowsy warning in response to determining that the driver has fallen asleep while driving; and
a warning module configured to output a warning to the driver based on the warning signal,wherein the drowsy pattern detection module is configured to determine whether a driver has fallen asleep considering a correlative changing pattern between the heartbeat rate based on the heartbeat signal and a level of steering based on the vehicle signal.

Abstract
A system for determining a drowsy state of a driver includes: a heartbeat measurement module configured to detect a heartbeat rate of the driver and output a heartbeat signal corresponding to the detected heartbeat rate; a vehicle signal measurement module configured to measure a driving state of a vehicle being driven by the driver and output a vehicle signal corresponding to the measured driving state; a drowsy pattern detection module configured to determine whether a driver has fallen asleep while driving based on the heartbeat signal and the vehicle signal and output a warning signal as a drowsy warning in response to determining that the driver has fallen asleep while driving; and a warning module configured to output a warning to the driver based on the warning signal.

6. A system for determining a drowsy state of a driver, the system comprising:
-
a heartbeat measurement module configured to detect a heartbeat rate of the driver and output a heartbeat signal corresponding to the detected heartbeat rate; a driver photographing module configured to measure a degree of eye closing of the driver and output an eye closing signal indicating the measured eye closing degree; a drowsy pattern detection module configured to determine whether the driver has fallen asleep while driving based on the heartbeat signal and the eye closing signal and output a warning signal as a drowsy warning in response to determining that the driver has fallen asleep while driving; and a warning module configured to output a warning to the driver based on the warning signal, wherein the drowsy pattern detection module is configured to determine whether a driver has fallen asleep considering a correlative changing pattern between the heartbeat rate based on the heartbeat signal and a long eye closing pattern based on the eye closing degree. - View Dependent Claims (7, 8)

9. A method for determining a drowsy state of a driver, the method comprising:
-
measuring a heartbeat rate of the driver and a driving state of a vehicle being driven by the driver;
determining whether the driver has fallen asleep while driving based on the heartbeat rate and the driving state; and
outputting a warning when it is determined that the driver has fallen asleep while driving,wherein the determining includes determining whether the driver has fallen asleep considering a correlative changing pattern between the heartbeat rate and a level of steering based on the vehicle signal. - View Dependent Claims (10, 11, 12, 13)
