Abstract

An abnormality detection device includes a motion detection unit that detects a motion indicating pain associated with a disease of a body of a driver based on motion information of the driver acquired by a camera, a behavior detection unit that detects abnormal behavior of a vehicle based on behavior information acquired by a vehicle behavior information acquisition unit, a biometric information detection unit that detects biometric information that is an abnormal sign of the driver based on biometric information acquired by the biometric information acquisition unit, and an abnormal sign determination unit that determines whether the driver shows an abnormal sign in the body by using all or some of a detection result of the motion detection unit, a detection result of the behavior detection unit, and a detection result of the biometric information detection unit.

Claims (27)

1 . An abnormality detection device comprising:

an input unit that inputs motion information and biometric information on a driver of a vehicle, and behavior information on the vehicle, the behavior information on the vehicle includes information from at least one of a vehicle speed sensor, a steering angle sensor, a camera, or a radar;

a detection unit that detects an abnormal sign of the driver based on the motion information, the biometric information, and the behavior information; and

an abnormal sign determination unit that determines whether the driver shows an abnormal sign in a body based on a detection result of the detection unit, wherein

a motion acquisition unit that acquires the motion information, and

the detection unit includes a motion detection unit that detects a motion indicating pain associated with a disease of the body of the driver based on the motion information acquired by the motion acquisition unit.

2 . The abnormality detection device according to claim 1 , wherein

the input unit includes a behavior acquisition unit that acquires the behavior information on the vehicle, and a biometric information acquisition unit that acquires the biometric information on the driver,

the detection unit includes a behavior detection unit that detects abnormal behavior of the vehicle based on the behavior information acquired by the behavior acquisition unit, and a biometric information detection unit that detects the biometric information that is the abnormal sign of the driver based on the biometric information acquired by the biometric information acquisition unit, and

the abnormal sign determination unit determines that the driver shows an abnormal sign in the body in a case where one or more of the motion detection unit and the biometric information detection unit detect the abnormal sign of the driver in combination with a case where the behavior detection unit detects the abnormal sign of the driver based on the abnormal behavior of the vehicle.

3 . The abnormality detection device according to claim 2 , wherein

the motion acquisition unit is a camera that captures an image of the driver, and

the motion detection unit is configured to detect at least the motion indicating pain of the driver in a case where a disease of the driver causes pain.

4 . The abnormality detection device according to claim 3 , wherein

the motion detection unit is configured to detect, as the motion indicating pain, at least a motion of holding a chest, a motion of holding a head, and a motion of holding a neck.

5 . The abnormality detection device according to claim 2 , wherein

the biometric information detection unit is configured to detect, as the biometric information generated by pain, at least an increase in the pulse rate by a predetermined value or more, an increase in the blood pressure by a predetermined value or more, and an increase in the respiratory rate by a predetermined number or more.

6 . An abnormality detection method comprising:

an input process of inputting motion information and biometric information on a driver of a vehicle, and behavior information on the vehicle, the behavior information on the vehicle includes information from at least one of a vehicle speed sensor, a steering angle sensor, a camera, or a radar;

a detection process of detecting an abnormal sign of the driver based on the motion information, the biometric information, and the behavior information; and

an abnormal sign determination process of determining whether the driver shows an abnormal sign in a body based on a detection result in the detection process, wherein

the detection process includes a motion detection process that detects a motion indicating pain associated with a disease of the body of the driver based on the motion information acquired by the input process.

7 . A non-transitory computer-readable storage medium storing an abnormality detection program that causes a computer to detect abnormality of a driver of a vehicle, the abnormality detection program causing the computer to execute processing comprising:

an input process of inputting motion information and biometric information on a driver of a vehicle, and behavior information on the vehicle, the behavior information on the vehicle includes information from at least one of a vehicle speed sensor, a steering angle sensor, a camera, or a radar;

a detection process of detecting an abnormal sign of the driver based on the motion information, the biometric information, and the behavior information; and

an abnormal sign determination process of determining whether the driver shows an abnormal sign in a body based on a detection result in the detection process, wherein

the detection process includes a motion detection process that detects a motion indicating pain associated with a disease of the body of the driver based on the motion information acquired by the input process.
