To provide a confluence support device, an on-vehicle unit, a confluence support system, a confluence support method, and a program capable of accurately predicting arrival timing of a main lane vehicle to a confluent zone before a confluence vehicle arrives at the confluent zone.SOLUTION: A confluence support device 10 includes: a speed detection section 111 for detecting a speed, at a first point, of a main lane vehicle traveling on a main lane; a prediction section 112 for predicting an arrival prediction time of the main lane vehicle at a confluence start point based on a distance from the first point to the confluence start point and the speed of the main lane vehicle at the first point; an error calculation section 113 for calculating an error of the arrival prediction time; and a correction section 114 for correcting the arrival prediction time of the main lane vehicle based on the error.SELECTED DRAWING: Figure 2
【課題】合流車両が合流区間に到達する前に、本線車両の合流区間への到達タイミングを精度よく予測することができる合流支援装置、車載器、合流支援システム、合流支援方法、及びプログラムを提供する。【解決手段】合流支援装置10は、本線を走行する本線車両の第1地点における速度を検出する速度検出部111と、前記第1地点から合流開始地点までの距離と、前記本線車両の前記第1地点における速度とに基づいて、前記本線車両の前記合流開始地点への到達予測時間を予測する予測部112と、前記到達予測時間の誤差を算出する誤差算出部113と、前記本線車両の前記到達予測時間を、前記誤差に基づいて補正する補正部114と、を備える。【選択図】図2
