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 vehicle control system includes a control unit for vehicle control and a server which distributes map information to the control unit. The map information includes information on a first type of road whereby full or partial driving assistance of the vehicle is possible, and information on a second type whereby full or partial driving assistance of the vehicle are not possible. The server includes an output unit which transmits information on a second type of road existing in a predetermined range from a first type of road on which the vehicle is traveling, and such that the first and second types of road form a predetermined angle or less. The control unit includes a map management unit including information on the first and second types of road, and a vehicle control unit controlling the vehicle by using the information on the first and second types of road.

Abstract: An object of the present invention is to suppress deterioration of comfort of autonomous driving due to on-road parking on a general road. The present invention is a vehicle control system including: a first map storage unit that stores first map information including lane information; a second map storage unit that stores second map information including property information including a store or a facility; a route acquisition unit that acquires a travel route of a vehicle; a property acquisition unit that acquires the property information adjacent to the travel route; and a determination unit that determines a recommended lane based on the property information, in which when the vehicle autonomously travels on a general road, it is possible to prevent deterioration of comfort or cancellation of autonomous driving due to a vehicle stopping on the road, and to notify of recommended travel lane information with increased prediction accuracy by determining whether or not there is a vehicle parked on a road by a combination of a store (static information) and a vehicle speed (dynamic information). In addition, it is possible to operate at low cost without communicating with the outside and without performing off-line map processing or the like.

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.

Abstract: Provided is an electronic control device that acquires route information to a destination based on first map information, and when a part of the route to the destination is outside a map range of any one of the first map information and second map information having a map range different from the first map information, changes the destination to generate a route to the destination based on the second map information.
