Title:
IN-VEHICLE ENVIRONMENT WARNING DEVICE AND IN-VEHICLE ENVIRONMENT WARNING METHOD
Document Type and Number:
Japanese Patent JP2020154976
Kind Code:
A
Abstract:
To accurately understand an in-vehicle environment for appropriately improving them.SOLUTION: An in-vehicle environment information acquisition unit 14 acquires in-vehicle environment information containing at least one index related to an environment in a vehicle chamber. A biological information acquisition unit 10 acquires biological information of a crew member of a vehicle. An arousal estimation unit 12 estimates an arousal level of the crew member from the biological information. A correlation information derivation unit 18 calculates a correlation level between the index and the arousal level in each crew member. The correlation information derivation unit 18 extracts the index having the correlation level of a prescribed value or more within the index contained in the in-vehicle environment information as a correlation index in each crew member, and derives correlation information defining warning condition of the correlation index in each crew member. An output unit 22 outputs warning to the crew member on the basis of the correlation level.SELECTED DRAWING: Figure 1
