Apparatus and method for controlling vehicle based on degree of fatigue
First Claim
1. An apparatus for controlling a vehicle based on a degree of fatigue of a driver, the apparatus comprising:
- a fatigue degree learning device configured to learn a degree of initial fatigue of the driver based on a heart rate variability (HRV) of the driver received from a sensor after a vehicle ignition is switched on;
a fatigue degree monitoring device that when learning the degree of initial fatigue of the driver is completed and driving of a vehicle is started, is configured to;
monitor the degree of current fatigue of the driver based on the HRV of the driver received from the sensor during the driving of the vehicle;
identify an increment state of the degree of fatigue by comparing the degree of current fatigue of the driver and the degree of initial fatigue of the driver; and
output a control signal corresponding to the increment state of the degree of fatigue of the driver; and
a driving controller configured to control the driving of the vehicle based on the control signal,wherein the fatigue degree learning device is configured to analyze a first HRV based on a frequency range during a learning period, and learn the degree of initial fatigue of the driver by first log values for a low frequency (LF) and a high frequency (HF) of the first HRV, andwherein the fatigue degree monitoring device is configured to analyze a second HRV based on the frequency range during a monitoring period, and detect the degree of current fatigue by second log values for a LF and a HF of the second HRV.
