Abnormality detection system and abnormality detection method

An abnormality detection system detecting an abnormality in a vehicle cabin, the abnormality detection system comprising:

• a cloud collecting data of a vehicle;
• an on-board device communicatively connected to the cloud;
• and
• a first application and a second application each configured to detect the abnormality as a target based on image data of an image captured by a camera, the camera capturing the image indicating an interior of the vehicle cabin,
• wherein
• the abnormality detected by the first application has an urgency level higher than an urgency level of the abnormality detected by the second application, the urgency level indicating a level to notify the abnormality in response to the abnormality being detected,
• the on-board device includes:
• a first detection unit analyzing the image data and detecting the abnormality when the first application is executed;
• a first transmission unit transmitting, to the cloud, an analysis result analyzed by the first detection unit and transmitting, to the cloud, at least the image data from which the abnormality is detected;
• and
• a second transmission unit transmitting, to the cloud, the image data when the second application is executed,
• the cloud includes:
• a first storage unit storing the analysis result and the image data transmitted from the first transmission unit when the first application is executed;
• a second detection unit analyzing the image data transmitted from the second transmission unit and detecting the abnormality, the image data being transmitted from the second transmission unit in response to execution of the second application;
• and
• a second storage unit storing the image data transmitted from the second transmission unit and an analysis result analyzed by the second detection unit, and
• at least one of the on-board device or the cloud notifies a notification target of the analysis result.

An abnormality detection system detecting an abnormality in a vehicle cabin, the abnormality detection system comprising:

• a cloud collecting data of a vehicle;
• and
• an on-board device communicatively connected to the cloud and communicatively connected to a relay device that relays a frame communicated through a network of the vehicle,
• wherein
• the on-board device includes:
• an on-board communication unit communicating with an electronic control unit connected to the network of the vehicle via the relay device;
• a detection unit analyzing image data of an image captured by a camera and detecting the abnormality in the vehicle cabin, the camera capturing the image indicating an interior of the vehicle cabin;
• and
• a transmission unit transmitting, to the cloud, an analysis result analyzed by the detection unit and transmitting, to the cloud, at least the image data from which the abnormality is detected, and
• the analysis result analyzed by the detection unit is notified toward outside of the vehicle.

An abnormality detection method detecting an abnormality in a vehicle cabin of a vehicle, an on-board device mounted on the vehicle being communicatively connected with a cloud, the abnormality detection method comprising:

• preparing a plurality of applications each configured to detect the abnormality as a target based on image data of an image captured by a camera, the camera capturing the image indicating an interior of the vehicle cabin;
• analyzing, with the on-board device, the image data and detecting the abnormality when each of the plurality of applications is executed;
• transmitting, with the on-board device, an analysis result of the image data and at least the image data from which the abnormality is detected, to the cloud;
• storing, in the cloud, the analysis result and the image data transmitted from the on-board device;
• and
• notifying, with at least one of the on-board device or the cloud, the analysis result to a notification target.
