Abstract: A control apparatus includes a controller configured to select, depending on a type of vehicle data obtained by monitoring a state of a vehicle, a driver or an owner of the vehicle as an authorized party who grants permission to provide the vehicle data to a third party other than the driver and the owner, and notify the selected authorized party of information prompting for the permission.

Abstract: A system includes a server including a controller. The controller is configured to obtain information regarding consent or non-consent of a user of a vehicle to disclosure of history data of the vehicle to a third party, and determine, when determination is made that consent of the user is not obtained, whether to transmit a signal that prompts for obtaining consent of the user, based on at least one of the history data of the vehicle and user activity information of the user.

Abstract: An information processing system includes an information processing device that records vehicle information of each individual vehicle. The information processing device includes a controller configured to send a first signal for collecting information on buying and selling of a first vehicle in secondary distribution, when the controller detects viewing of vehicle information of the first vehicle.

Abstract: An information processing device stores vehicle information on each of a plurality of vehicles, and the information processing device includes one or more processors configured to: acquire an attribute of a user who browses the vehicle information; and change a display content that is the vehicle information displayed on a terminal device based on the attribute.

Abstract: A controller of an information processing apparatus acquires, in a case in which a previous user of a vehicle has given consent to disclose history data for the vehicle, information indicating whether a current user of the vehicle has given consent to disclose the history data for the vehicle, and determines to grant the current user an incentive in a case in which it is determined, based on the acquired information, that the current user has given consent to disclose the history data for the vehicle.

Abstract: A server includes a controller that repeatedly acquires history data for a vehicle, and limits data items acquired as the history data in a case in which an age of the vehicle is greater than or equal to a first threshold.

Abstract: A controller of an information processing apparatus acquires, in a case in which a previous user of a vehicle has not given consent to disclose history data for the vehicle, information indicating whether a current user of the vehicle has given consent to disclose the history data for the vehicle, and determines to grant the current user an incentive in a case in which it is determined, based on the acquired information, that the current user has given consent to disclose the history data for the vehicle.

Abstract: A battery state estimating unit estimates an internal state of a secondary battery in accordance with a battery model equation in every arithmetic cycle, and estimates a charging rate and a battery current based on a result of the estimation. A parameter estimating unit obtains a battery current measured by a sensor as well as the charging rate and the battery current estimated by the battery state estimating unit. The parameter estimating unit estimates a capacity deterioration parameter such that a rate of change in difference (estimation error) between a summed value of an actual current and a summed value of an estimated current with respect to the charging rate is minimized. A result obtained by estimating the capacity deterioration parameter is reflected in the battery model by the battery state estimating unit.
