Embodiment Construction
[0047]Hereinafter, a vehicle control device according to a first embodiment of the present invention will be described with reference to the drawings. The vehicle control device of the present embodiment is mounted on a vehicle, and is used to perform vehicle control for improving traffic volume on a road. Such as figure 1 As shown, the vehicle control device 10 a of the present embodiment includes a navigation system 16 , an ECU (Electronic Control Unit: Electronic Controller) 20 , and an ACC (Adaptive Cruise Control: Adaptive Cruise Control) 30 .
[0048] The navigation system 16 includes: a GPS receiver that receives signals from a plurality of GPS (Global Positioning System: Global Positioning System) satellites, and measures the position of the vehicle according to the difference between the signals; DB (DataBase: database). The navigation system 16 is used not only to guide the route of the own vehicle, but also to obtain information on places where the vehicle speed d...

A navigation system 16 acquired information relating to a point, such as a sag 520 where a decrease in vehicle speed is induced in front of a system-mounted vehicle 100. When the system-mounted vehicle 100 has reached a predetermined distance from the sag 520 concerning the information acquired by the navigation system 16 or when a predetermined time has come before reaching the sag 520, an ECU 20 and an ACC 30 controls the traveling of the system-mounted vehicle 100 such that the inter-vehicle distance from an ordinary vehicle 200 behind the system-mounted vehicle 100 increases. Therefore, even when a vehicle control device 10a is not mounted in an ordinary vehicle 200x behind the system-mounted vehicle 100, it becomes possible to prevent a decrease in the speed of the ordinary vehicle 200x behind the system-mounted vehicle 100, thereby more effectively suppressing congestion.
Description
technical field [0001] The present invention relates to a vehicle control device, a vehicle control method, and a vehicle control system, and in particular to a vehicle control device, a vehicle control method, and a vehicle control system for improving road traffic. Background technique [0002] Conventionally, attempts have been made to improve the traffic volume of roads and alleviate traffic congestion by controlling the running of individual vehicles. For example, Patent Document 1 discloses a traffic jam prevention device. In order to prevent the occurrence of traffic jams, the traffic jam prevention device acquires information indicating that there is a cause of traffic jam on the road on which the vehicle is traveling, and acquires information indicating that the vehicle is traveling. information about the action of the vehicle, thereby judging whether the action of the own vehicle is an action that causes a traffic jam corresponding to the cause of the traffic jam. ...
