PROBLEM TO BE SOLVED: To prevent decrease in reliability of driving support in a driving support system which performs driving support by using information exchanged between vehicles by inter-vehicle communication.SOLUTION: A driving support unit used in a vehicle comprises a transmission processing part 253 which causes vehicle information including the vehicle position of the own vehicle positioned by using a GPS to be transmitted by inter-vehicle communication. If a deterioration detection part 252 detects deterioration of positioning accuracy of the vehicle position of the own vehicle positioned by using the GPS, the transmission processing part 253 prevents the vehicle information from being transmitted.

    【課題】車車間通信によって車両間でやり取りする情報を用いて運転支援を行う運転支援システムにおいて、運転支援の信頼度が低下するのを防ぐことを可能にする。【解決手段】車両で用いられ、GPSを用いて測位した自車の車両位置を含む車両情報を、車車間通信によって送信させる送信処理部253を備え、送信処理部253は、GPSを用いて測位した自車の車両位置の測位精度が劣化していることが劣化検出部252で検出された場合に、車両情報を送信させないようにする。【選択図】図2
