APPARATUS FOR DETECTING DRIVER'S MENTAL STATE AND METHOD FOR DETECTING MENTAL STATE
First Claim
1. A mental state detection apparatus comprising:
- a plurality of detection units configured to detect a driver'"'"'s state;
an appearance determination unit configured to determine a driver'"'"'s appearance from the detection results of the detection units;
a mental state determination unit configured to determine a driver'"'"'s mental state from the detection results of the detection units; and
switching unit configured to switch the outputs from the detection units to the mental state determination unit on the basis of a determination result of the appearance determination unit.

Abstract
The reliability of detection of a driver'"'"'s mental state in a vehicle in a driving state is enhanced without impairing operation stability of driving action of the vehicle.
There are provided an imaging section 11 and a heart rate sensor 12 that serve as a plurality of detection means for detecting a driver'"'"'s state; an appearance determination section 13 for determining a driver'"'"'s appearance from detection results from the imaging section 11 and the heart rate sensor 12; and a mental state determination section 15 for determining a driver'"'"'s mental state from the detection results from the imaging section 11 and the heart rate sensor 12. A switching section 14 switches the outputs from the imaging section 11 and the heart rate sensor 12 to an output from the mental state determination section 15 on the basis of a determination result from the appearance determination section 13.

15. A mental state detection method comprising:
-
detecting a driver'"'"'s state by a plurality of detection units; determining a driver'"'"'s appearance on the basis of detection result of the detecting step; determining a driver'"'"'s mental state on the basis of the detection result of the detecting step by a mental state determination unit; and of switching outputs from the detection units to the mental state determination unit on the basis of the determining result of the driver'"'"'s mental state determining step.
