A data collection apparatus includes a processor and a storage. The processor is configured to: estimate an emotion of a person watching an own vehicle on the basis of an image data of a surrounding environment of the own vehicle; generate emotion data including an estimate of the emotion of the person watching the own vehicle; specify a state of the own vehicle viewed by the person watching the own vehicle; and correlate the emotion data with the specified state of the own vehicle. The storage is configured to be caused by the processor to store the emotion data correlated with the specified state of the own vehicle.

Data collection apparatus for estimating emotion of a person watching vehicle

A vehicle controller includes a processor that switches, when detecting a physical abnormality of an occupant of an own vehicle based on physical information of the occupant, the own vehicle to an emergency mode in which the own vehicle automatically travels to a destination. The processor receives, when the own vehicle is switched to the emergency mode, other vehicle information from another vehicle switched to the emergency mode. The other vehicle information includes information on a physical abnormality of an occupant of the other vehicle. Based on the other vehicle information and own vehicle information including information on the physical abnormality of the occupant of the own vehicle, the processor sets the order of priority to determine which of the own vehicle or the other vehicle is allowed to travel preferentially, and sends, based on the order of priority, a medical aid request to an information processor.

Vehicle controller and vehicle control system

A driving assistance apparatus includes a first emotion estimating unit, a second emotion estimating unit, a storage, and a notification controller. The first emotion estimating unit is configured to estimate an emotion of a driver of a vehicle. The second emotion estimating unit is configured to estimate an emotion of a traffic participant around the vehicle. The storage is configured to store data on a first location where the driver of the vehicle has felt no danger and the traffic participant has felt danger from the vehicle. The notification controller is configured to notify the driver of the stored data on the first location.

Driving assistance apparatus and data collection system

An automated driving assistance apparatus includes an occupant's emotion learning section and a control parameter setting section. The occupant's emotion learning section creates an occupant's emotion model based on vehicle driving state information and occupant's emotion information. The occupant's emotion model is used to estimate an emotion of the occupant from a vehicle driving state. The control parameter setting section calculates an ideal driving state based on the occupant's emotion model, and set a control parameter for automated driving of the vehicle based on the ideal driving state. The control parameter setting section output input values relevant to the vehicle driving state to the occupant's emotion model, and select, from the input values received by the occupant's emotion model, an input value that causes a current occupant's emotion to become closer to a target emotion as the ideal driving state of the vehicle.

Automated driving assistance apparatus

A drive assist apparatus includes a processor and a storage. The processor includes a line-of-sight detector, an emotion estimator, and a notification processing unit. The line-of-sight detector detects information on a line of sight of one or both of a vehicle occupant present in a vehicle and a traffic participant present around the vehicle. The emotion estimator estimates an emotion of the one or both of the vehicle occupant and the traffic participant. The storage stores, when the estimated emotion is detected as a positive emotion, data on a viewpoint including information on a position of the vehicle on map data and information on the line of sight. The notification processing unit makes, on the basis of the data on the viewpoint stored in the storage, a notification of information on a direction to notice to the vehicle occupant present in the vehicle traveling through a location corresponding to the viewpoint.
