Abstract: An electronic control device is mounted on a vehicle and executes automatic driving control using a plurality of pieces of map information. Each piece of the map information includes one or more pieces of partial data corresponding to a predetermined geographical area and being information of a predetermined attribute related to a road of the predetermined geographical area. The electronic control device includes a storage unit that stores one or more pieces of the map information, a specification unit that specifies the map information corresponding to a traveling position of the vehicle, and a control unit that determines a control method of the vehicle at a traveling position of the vehicle according to the partial data included in the map information specified by the specification unit.

Abstract: A data transfer apparatus includes an acquisition side communication port that receives data including an identifier indicating a classification from an outside, a distribution side communication port that transmits the data to the outside, a storage unit that stores transfer information in which the identifier and a condition related to a time of the data are associated, and a transfer processing unit that decides whether or not to transmit received data which is the data to the distribution side communication port based on the identifier included in the received data and information of the time of the received data, and the transfer information when the received data is received by the acquisition side communication port. The information of the time of the received data is a time at which the received data is received by the acquisition side communication port or a time included in the received data.

Abstract: An electronic control device that is mounted on a vehicle and performs automated driving control using map information includes: a storage unit that stores basic map data; a communication unit that communicates with a data center to acquire map data managed by the data center as external map data; and a processing unit that determines a control mode of the automated driving control according to the acquired external map data and performs the automated driving control based on the determined control mode, position information of the vehicle, the basic map data, and the external map data.
With the configuration, availability of map information is secured and continuity of an automated driving function is improved even in a case where a communication situation is not good while a required storage capacity is suppressed by limiting the map information stored in the vehicle.
