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. like 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 drop...

Abstract

A navigation system (16) acquires information relating to a location such as a sug (520) inducing lowering of velocity of a vehicle preceding a system-mounting vehicle (100). When the system-mounting vehicle (100) has reached a predetermined distance of the sug (520) relating to the information acquired by the navigation system (16) or a predetermined time has come before reaching the sug (520), an ECU (20) and an ACC (30) control the running of the system-mounting vehicle (100) so as to increase the inter-vehicle distance between the system-mounting vehicle (100) and a following vehicle (200). Thus, even if no vehicle control device (10a) is mounted on the following vehicle (200x) behind the system-mounting vehicle (100), it is possible to prevent the velocity lowering of the vehicle (200x) behind the system-mounting vehicle (100), thereby effectively suppressing the 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. ...
