The data collection device 2 and the information processing device 3 are communicably connected via a communication network N such as the Internet. In the information processing system 1 , a plurality of data collection devices 2 are communicably connected to the information processing device 3 .

The data collection device 2 is, for example, an in-vehicle device. The in-vehicle device is, for example, a drive recorder. Here, a case where the data collection device 2 is the drive recorder 2 will be described as an example.

The drive recorder 2 includes an in-vehicle camera (not shown). An in-vehicle camera includes, for example, a lens and an imaging device. The imaging device is a CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor). The in-vehicle camera is provided at a position capable of capturing images of the front, rear, left and right sides of the own vehicle, for example. A plurality of in-vehicle cameras may be provided. An in-vehicle camera images the surroundings of the vehicle. An on-board camera acquires images of the surroundings of the vehicle. The image is a moving image.

The drive recorder 2 collects data related to vehicle events. The vehicle event-related data includes at least one of vehicle accident-related data and dangerous driving-related data.

Vehicle accidents include contact accidents between the own vehicle and other vehicles, self-damage accidents of the own vehicle, contact accidents between the own vehicle and people, and the like.

Dangerous driving is driving that does not result in a vehicle accident but may lead to a vehicle accident. For example, dangerous driving includes sudden braking and sudden steering.

The data related to the vehicle event includes data that is an occurrence element of the vehicle event. A vehicle event occurrence element is an element that can cause an event when a vehicle event occurs. Vehicle event generation elements are, for example, the color of traffic light lights, the speed state of the vehicle, and the brake operation state of the vehicle. The vehicle event occurrence element includes at least one of the color of the traffic light, the speed state of the vehicle, and the brake operation state of the vehicle.

The drive recorder 2, for example, identifies a traffic light by executing predetermined image processing based on image data captured by an in-vehicle camera, and further identifies the color of the light of the identified traffic light.

The drive recorder 2 acquires the speed of the vehicle from a vehicle speed sensor (not shown) through CAN communication, for example. The drive recorder 2 determines whether or not the vehicle complies with the legal speed limit based on the obtained vehicle speed. That is, the drive recorder 2 determines whether the speed state of the vehicle is a compliance state in which the speed is equal to or less than the legal speed, or whether the speed state of the vehicle is in a violation state in which the speed is higher than the legal speed. Based on the vehicle position information, the drive recorder 2 acquires the legal speed limit of the road on which the vehicle is traveling, and determines whether the vehicle complies with the legal speed limit. Vehicle position information is received, for example, from a GPS (Global Positioning System) device. The legal speed of the road is stored, for example, in association with the map information.

The drive recorder 2 acquires a signal regarding the brake operation state from a brake sensor (not shown) by CAN communication, for example. The brake operation state includes an operation state in which the brake pedal is depressed and a non-operation state in which the brake pedal is not depressed. For example, when the depression amount of the brake pedal is larger than a predetermined depression amount, it is determined that the brake operation state is the operation state. When the depression amount of the brake pedal is equal to or less than the predetermined depression amount, the brake operation state is determined to be the non-operation state.

The drive recorder 2 stores data related to vehicle events in association with the date and time when the data was acquired. The drive recorder 2 stores data related to vehicle events for a predetermined storage time. The predetermined storage time is a preset time, such as 10 seconds. When the drive recorder 2 acquires new vehicle event-related data, the drive recorder 2 sequentially erases old vehicle event-related data and updates the vehicle event-related data at a predetermined storage time.

In addition, the drive recorder 2 stores the environmental data of the vehicle and the travel data of the vehicle in association with the date and time when the data was acquired. The drive recorder 2 stores vehicle environment data for a predetermined storage time and vehicle travel data for a predetermined storage time. The drive recorder 2 updates vehicle environment data and vehicle travel data, as well as data related to vehicle events.

The vehicle environment data includes weather information and brightness information around the vehicle. The drive recorder 2, for example, acquires weather information from an external information providing server (not shown).

Vehicle environmental data may include temperature.

The travel data of the vehicle includes the lighting state of the headlights (not shown) of the vehicle, the speed information of the vehicle, the acceleration information of the vehicle, and the position information of the vehicle. The drive recorder 2 acquires a signal regarding the lighting state of the headlight from a sensor that detects the lighting state of the headlight, for example, through CAN communication. The drive recorder 2 acquires a signal regarding vehicle acceleration from an acceleration sensor (not shown), for example, through CAN communication.

When a predetermined transmission condition is satisfied, the drive recorder 2 transmits data related to vehicle events for a predetermined storage time, vehicle environmental data for a predetermined storage time, and vehicle travel data for a predetermined storage time. It transmits to the information processing device 3 via the communication network N. The drive recorder 2 includes a communication device (not shown) for transmitting data related to vehicle events to the information processing device 3 . The drive recorder 2 transmits to the information processing device 3 vehicle event data for a predetermined storage time before and after the time when the predetermined transmission condition is satisfied, when the predetermined transmission condition is satisfied.

Specifically, when a predetermined transmission condition is satisfied, the drive recorder 2 stores data related to vehicle events for a predetermined storage time, vehicle environment data for a predetermined storage time, and vehicle data for a predetermined storage time. , the date and time when each data was acquired, and image data for a predetermined storage time are linked to the device ID assigned to the drive recorder 2 and transmitted to the information processing device 3 . The device ID is identification information that identifies the drive recorder 2 . The device ID may be associated with vehicle information on which the drive recorder 2 is installed, information on the owner of the vehicle, and the like.

The predetermined transmission condition is a condition under which it can be determined that an event has occurred in the vehicle. The drive recorder 2 determines that a vehicle accident has occurred when the acceleration of the vehicle reaches or exceeds a predetermined acceleration, and determines that a predetermined transmission condition is satisfied.

Further, the drive recorder 2 determines that a sudden brake operation has occurred and dangerous driving has occurred when the amount of increase in the amount of depression of the brake pedal per unit time is equal to or greater than a predetermined amount of increase. The amount of increase in depression of the brake pedal is calculated based on the signal obtained from the brake pedal sensor.

The drive recorder 2 determines that a sudden steering operation has occurred and dangerous driving has occurred when the amount of operation of the steering wheel per unit time is equal to or greater than a predetermined amount of operation set in advance. The steering wheel operation amount is detected by, for example, a steering angle sensor (not shown). Note that the drive recorder 2 detects that when the vehicle speed is equal to or higher than a predetermined vehicle speed and the amount of operation of the steering wheel per unit time is equal to or higher than a predetermined amount of operation, a sudden steering operation is performed. It may be determined that dangerous driving has occurred.
