PROBLEM TO BE SOLVED: To prevent reverse running determination by a reverse running determination device from being affected by an installation condition of an IC card to an on-vehicle device and performance of an infrastructure.SOLUTION: A reverse running determination device comprises receiving means (11) installed on a vehicle for receiving an identification code that can identify a roadside machine (SP) from the roadside machine, storage means (10D) for storing an identification code received at latest among the identification codes received by the receiving means, and reverse running determination means (10) for determining that the vehicle is running in reverse when the receiving means receives the same identification code as one received at latest that is stored by the storage means after the identification code is no longer received from the roadside machine.SELECTED DRAWING: Figure 1
【課題】逆走判断装置による逆走の判断の可否に、車載器に対するICカードの装着状態やインフラ側の性能が影響を及ぼすのを抑制すること。【解決手段】車両に搭載され、路側機(SP)から当該路側機を識別可能な識別符号を受信する受信手段(11)と、該受信手段が受信した前記識別符号のうち、直近に受信された識別符号を記憶するための記憶手段(10D)と、前記受信手段が、前記路側機から前記識別符号を受信しなくなった後、前記記憶手段に記憶された前記直近に受信された識別符号と一致する識別符号を受信したとき、前記車両が逆走していると判断する逆走判断手段(10)と、を備える。【選択図】図1
