An information output control method includes a step of deriving a driving load of a driver, based on a traveling environment or a driving state of the driver, a step of deciding to suggest a content that meets the derived driving load, to the driver, and a step of calculating a degree of acceptance of the suggested content by the driver. In the deciding step, the frequency of suggestion of the content or the type of the content is set based on the calculated degree of acceptance.

Information output control method and information output control system

An interaction device include a processor. The processor being configured to acquire an alertness level of an occupant of a vehicle, request an utterance from the occupant in a case in which the acquired alertness level is below a threshold value, identify a rest point at which the vehicle can stop, measure a cycle spanning from initiation of an interaction until the alertness level falls below the threshold value again, and repeatedly request an utterance from the occupant at a regular interval that is shorter than the measured cycle during a time period from notifying the occupant that the rest point has been set as a destination of the vehicle to the vehicle arriving at the destination.

Interaction device, interaction method, and storage medium storing program

An information output system includes a speech acquisition unit configured to acquire a speech of a user, a recognition processing unit configured to recognize the content of the acquired speech of the user, and an output processing unit configured to output a question to the user and to perform processing for outputting a response to the content of the speech of the user who has answered the question. The output processing unit is configured to derive a user's positive degree based on the content of the speech of the user who has answered the question and to determine guidance information to be output to the user based on the derived positive degree.

Information output system and information output method

An information processing method includes a step of obtaining article information including a category of an article which a user wishes to purchase, and a step of outputting a reminder concerning purchase of the article, when a reminding condition is satisfied in a reminding period that is set according to the category of the article obtained.

Method and system for level of difficulty determination using a sensor

A driving assistance device includes: a vehicle group search unit that acquires a most frequent vehicle speed of the vehicle and to search for one or more vehicle group, the most frequent vehicle speed being a vehicle speed that is most frequent, the vehicle group traveling at one of the most frequent vehicle speed and a speed close to the most frequent vehicle speed; a distance information generation unit that generates the vehicle group searched for by the vehicle group search unit and distance information on a distance between the vehicle group and an information-receiving vehicle that has sent the most frequent vehicle speed; and a merging assistance unit that sends the distance information generated by the distance information generation unit to a user terminal device and assists the vehicle in merging into one of the vehicle groups searched for by the vehicle group search unit.

Driving assistance device, vehicle driving assistance system, control method of driving assistance device, and non-transitory recording medium storing program

A parking lot guidance device includes a processor. The processor is configured to cause a communication unit to transmit exit information to a vehicle with the highest priority among other vehicles that are transmission targets. The exit information includes information of a size of a parking section in which a host vehicle is parked, information of a position of the parking section in which the host vehicle is parked, and information of a start of exit of the host vehicle.

Parking lot guidance device

A driving support device includes a memory and a processor including hardware. When a vehicle is placed inside a rest facility and at least one of parameters indicative of respective states of traffic jams on roads ahead of and behind the rest facility satisfy a predetermined reference, the processor transmits, to a device related to the vehicle, information that proposes a departure from the rest facility.

Driving support device, driving support method, and program

A road surface submergence estimation device including a motion sensor that acquires an actual acceleration of a vehicle; a torque acquisition sensor that acquires an actual torque transmitted from a driving source to wheels of the vehicle, the driving source being mounted in the vehicle; and an estimation processor that estimates that a road surface on which the vehicle is traveling is submerged when it is determined that a submergence determination condition is satisfied. The road surface submergence estimation device may also include a wireless communication device configured to either send submergence information to a central server, or receive additional submergence information from a central server.
