## Abstract

A dangerous driving detection device includes: an acquisition section that acquires image information, which expresses captured images that are captured by an imaging section provided at a vehicle, and vehicle information that expresses a state of the vehicle; plural detection sections that, based on the image information and the vehicle information acquired by the acquisition section, detect types of dangerous driving that are respectively different from one another; and a deriving section that, based on results of detection of the plural detection sections, derives a degree of danger of dangerous driving of a driver.

## Claims

### Claim 1

A dangerous driving detection device comprising:
a memory: and
a processor coupled to the memory, and configured to:
acquire image information, which expresses captured images that are captured by an imaging section provided at a vehicle, and vehicle information that expresses a state of the vehicle;
based on the acquired image information and the acquired vehicle information, detect a plurality of different types of dangerous driving; and
based on results of detection of the plurality of types of dangerous driving, derives a degree of danger of dangerous driving of a driver.

### Claim 2 (depends on 1)

The dangerous driving detection device of claim 1, wherein the processor is further configured to identify a traveling scenario based on the image information and the vehicle information, and detect dangerous driving that corresponds to the identified traveling scenario.

### Claim 3 (depends on 2)

The dangerous driving detection device of claim 2, wherein the processor is further configured to change a detection threshold value, which is for detecting dangerous driving, to a predetermined detection threshold value in accordance with the traveling scenario, to detect the dangerous driving.

### Claim 4 (depends on 2)

The dangerous driving detection device of claim 2, wherein the traveling scenario includes at least one traveling scenario of type of road, weather, time range, or accident occurrence rate at a place of traveling.

### Claim 5 (depends on 1)

The dangerous driving detection device of claim 1, wherein the processor is further configured to carry out processing that synchronizes the image information and the vehicle information by performing time matching of the image information and the vehicle information.

### Claim 6 (depends on 1)

A dangerous driving detection system comprising:
the dangerous driving detection device of claim 1; and
a vehicle that includes the imaging section and a vehicle information detection section that detects the vehicle information.

### Claim 7

A dangerous driving detection method comprising:
acquiring image information, which expresses captured images that are captured by an imaging section provided at a vehicle, and vehicle information that expresses a state of the vehicle;
based on the acquired image information and the acquired vehicle information, detecting types of dangerous driving that are respectively different from one another; and
based on results of detection, deriving a degree of danger of dangerous driving of a driver.

### Claim 8

A non-transitory storage medium that stores a program that is executable by a computer to perform dangerous driving detection processing, the dangerous driving detection processing comprising:
acquiring image information, which expresses captured images that are captured by an imaging section provided at a vehicle, and vehicle information that expresses a state of the vehicle;
based on the acquired image information and the acquired vehicle information, detecting types of dangerous driving that are respectively different from one another; and
based on results of detection, deriving a degree of danger of dangerous driving of a driver.
