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: Provided are an electronic control device and a vehicle control system capable of reducing a calculation amount and improving reliability of a travel route of a vehicle as compared with a conventional course setting device. An electronic control device 200 is mounted on a vehicle 100. The electronic control device 200 includes a map processing device 210 connected to an external sensor 110 that recognizes an obstacle around the vehicle 100 and a position sensor 120 that acquires position information of the vehicle 100 in a manner capable of information communication. The map processing device 210 includes a storage device 212 that stores map information including travel route information of the vehicle 100. The map processing device 210 records a travel route along which the vehicle 100 avoids an obstacle in the storage device 212, classifies the obstacle into a permanent obstacle and a transient obstacle, and updates the travel route information with an avoiding route based on the travel route along which the vehicle 100 has avoided the permanent obstacle.

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.
