PROBLEM TO BE SOLVED: To provide a method and device for warning collision of a vehicle which is not interfered with an obstacle nor affected by presence of sun's light.SOLUTION: A signal that notifies position and state of an own vehicle is detected, and a signal that reports position and state of a target vehicle is received. Signals are respectively converted to a speed. A relative speed and a relative position of a vehicle after a time interval are acquired. In a case where it is determined that a normal distance from the own vehicle to a line representing direction of the relative speed is minimum and being a warning distance or less, a driver of the own vehicle receives warning.

    【課題】障害物に妨害されたり、日光の有無によって影響を受けない、車両の衝突を警告する装置および方法を提供する。【解決手段】本車両の位置および状態を通知する信号を検知し、対象車両の位置および状態を報告する信号を受信する。信号はそれぞれ速度に変換される。時間間隔後の車両の相対速度および相対位置を取得する。本車両から相対速度の方向を示す線への通常距離が最小であり、警告距離以下であると判断された場合、本車両の運転手は警告を受ける。【選択図】図3
