Abstract: An occupant detection device includes: an occupant detection unit to output detection results about occupants, each of the detection results being detected using an electric wave and being about a corresponding one of seat positions of the occupants; an output determination unit to output the detection results in accordance with the vibration amount of the vehicle; a storage control unit to store the detection results while linking the detection results with the seat positions; and a movement detection unit to detect a movement as to each occupant detected using means other than an electric wave. When the movement detection unit detects a movement of an occupant in a state where no detection result is outputted from the output determination unit, the storage control unit corrects a link between a detection result and a seat position which are stored.

Abstract: An operation restriction control device includes processing circuitry configured to set restriction on the manual operation input to a valid state in a case where a vehicle is traveling, set the restriction on the manual operation input to an invalid state when a voice command corresponding to release of the restriction on the manual operation input is input to the first operation input device by a passenger in the vehicle in a state where the restriction on the manual operation input is set to a valid state, and set the restriction on the manual operation input to a valid state when a duration during which a line of sight of a driver of the vehicle is directed to the in-vehicle information device has exceeded a first reference time in a state where the restriction on the manual operation input is set to an invalid state.

Abstract: A speech signal processing unit individually separates uttered speech of a plurality of passengers each seated in one of a plurality of speech recognition target seats in a vehicle. A speech recognition unit performs speech recognition on uttered speech of each of the passengers separated by the speech signal processing unit and calculates a speech recognition score. A score-using determining unit determines a speech recognition result of which of the passengers is to be used from among speech recognition results for the passengers, using the speech recognition score of each of the passengers.

Abstract: Processing circuitry acquires a captured image in which an occupant of a vehicle is captured having an optical axis parallel to a moving direction of a seat movable back and forth, detects skeleton coordinate points of the occupant on the basis of the captured image, calculates, on the basis of the skeleton coordinate points, a correction amount on the basis of a ratio between a first distance that is a horizontal distance from a straight line passing through a center of and parallel to a longitudinal direction of the captured image to a correction amount calculating skeleton coordinate point and a second distance that is a horizontal distance from the straight line to a reference coordinate point on the captured image corresponding to the correction amount calculating skeleton coordinate point, and estimates a physique of the occupant on the basis of the skeleton coordinate points and the correction amount.

Abstract: A correspondence relationship between keywords for instructing the start of a speech dialogue and modes of a response is defined in a response-mode correspondence table. A response-mode selecting unit selects a mode of a response corresponding to a keyword included in the recognition result of a speech recognition unit using the response-mode correspondence table. A dialogue controlling unit starts the speech dialogue when the keyword is included in the recognition result of the speech recognition unit, determines a response in accordance with the subsequent recognition result from the speech recognition unit, and controls a mode of the response in such a manner as to match the mode selected by the response-mode selecting unit. A speech output controlling unit generates speech data on the basis of the response and mode controlled by the dialogue controlling unit and outputs the speech data to a speaker.
