Abstract: A vehicle includes an information storage, an information notifier, a reply acquirer, a vehicle characteristic specifier, and a vehicle characteristic setter. The information storage is configured to store question information including a plurality of questions. The information notifier is configured to extract a question from the stored question information in accordance with a predetermined rule and notify the question through a notification device. The reply acquirer is configured to acquire a reply to the notified question. The vehicle characteristic specifier is configured to specify a vehicle characteristic based on the reply. The vehicle characteristic setter is configured to set the specified vehicle characteristic is the vehicle.

Abstract: A vehicle control apparatus to be used in a vehicle controllable on the basis of a voice input includes a determination unit and an input unit. The determination unit is configured to determine whether a main operator of the vehicle is in a predetermined state where the main operator is not possible to perform an operation or is not performing an operation. The input unit is configured to accept an operational input based on a voice of the main operator, as well as to accept an operational input based on a voice of a passenger of the vehicle in a case where the determination unit has determined that the main operator is in the predetermined state.

Abstract: A vehicle system includes a first vehicle and a second vehicle. The first vehicle includes an information storage configured to store vehicle characteristic information representing a vehicle characteristic, and an information output unit configured to output the stored vehicle characteristic information to a predetermined storage medium. The second vehicle includes an information input unit configured to input vehicle characteristic information from the storage medium, and a vehicle characteristic setter configured to set a vehicle characteristic represented by the input vehicle characteristic information in the second vehicle.

Abstract: A driving assistance apparatus includes a risk prediction unit, a driving assistance control unit, a detection unit, and a first data storage. The risk prediction unit predicts a risk state of a vehicle on the basis of the vehicle's traveling state information and surrounding environment information. The driving assistance control unit executes driving assistance control on the basis of the predicted risk state. The detection unit acquires biological information of an occupant of the vehicle, and detects that the occupant feels danger on the basis of the biological information. The first data storage stores a learning model constructed by accumulating the vehicle's traveling state information and surrounding environment information obtained when the danger is felt. The driving assistance control unit executes the driving assistance control on the basis of the predicted risk state and the vehicle's traveling state information and surrounding environment information obtained when the danger is felt.

Abstract: A vehicle system includes an information storage, an information acquirer, a vehicle characteristics extractor, and a vehicle characteristics transmitter. The information storage stores vehicle information of sample vehicles in association with the sample vehicles. The vehicle information is obtained by combining a traveling location or a traveling environment, or both, with vehicle characteristics. The information acquirer acquires vehicle information of a target vehicle and either of both of a first traveling location and a first traveling environment for which vehicle characteristics for the target vehicle are lacking. The vehicle characteristics extractor determines a sample vehicle of which vehicle information matches the vehicle information of the target vehicle and extracts vehicle characteristics of the sample vehicle corresponding to either or both of the first traveling location and the first traveling environment.
