VEHICLE CONTROL SYSTEM

PROBLEM TO BE SOLVED: To provide a vehicle control system for safely controlling a vehicle when a road side device and an on-vehicle device cannot perform road-vehicle communication.SOLUTION: When a road side device and an on-vehicle device cannot perform road-vehicle communication (S24: No), a server predicts a travel track after a current time point N(t) of a vehicle that is not communicable on the basis of reception information before a preceding time point N(t-1) (S25). Then, the server identifies vehicles approaching a predicted travel track, reduces a value of a travel speed command at the current time point N(t) to be lower than a value of a travel speed command at the preceding time point N(t-1) by a predetermined value ΔS with respect to the vehicles, and transmits the travel speed command at the current time point N(t) (S26). The on-vehicle device holds a travel route command at the preceding time point N(t-1), reduces the value of the travel speed command at the current time point N(t) to be lower than the value of the travel speed command at the preceding time point N(t-1) by the predetermined value, and generates the travel speed command at the current time point N(t) (S7).SELECTED DRAWING: Figure 4 【課題】路側装置と車載装置とが路車間通信できない場合において安全に車両を制御する車両制御システムを提供する。【解決手段】路側装置と車載装置の路車間通信ができない場合Ｓ２４Ｎｏ、サーバは、前回時刻時点Ｎ（ｔ−１）までの受信情報に基づいて、通信不可の車両の現在時刻時点Ｎ（ｔ）以降の走行軌跡を予測しＳ２５、予測した走行軌跡に近づく車両を特定し、これらの車両に対し、現在時刻時点Ｎ（ｔ）の走行速度指令の値を、前回時刻時点Ｎ（ｔ−１）の走行速度指令の値よりも所定値ΔＳ低下させ、現在時刻時点Ｎ（ｔ）の走行速度指令を送信するＳ２６。車載装置は、前回時刻時点Ｎ（ｔ−１）の走行経路指令を保持し、現在時刻時点Ｎ（ｔ）の走行速度指令の値を、前回時刻時点Ｎ（ｔ−１）の走行速度指令の値よりも所定値低下させ、現在時刻時点Ｎ（ｔ）の走行速度指令を生成するＳ７。【選択図】図４
