NOTIFICATION DEVICE OF AN APPROACHING VEHICLE

In a notification device of an approaching vehicle (10) which detects an approach of the other vehicle running a crossroad intersecting a run way of an own vehicle at an anterior intersection and an arrival direction thereof by a radar sensor (33) and notifies a driver thereof, a reflection distance-acquisition part (25) computes a value according to a difference between an absolute value of an X-axis component (Xr) of a relative position of the other vehicle acquired by the radar sensor and an absolute value of an X-axis component (Xc) of a converted relative position of the other vehicle acquired by a relative-position acquisition part (24), in an X-Y coordinate space with its origin set at a location of the own vehicle, a Y-axis set in a traveling direction of the own vehicle and an X-axis set in a direction perpendicular to the Y-axis, as a reflection distance-correlation value (reflection distance Xw). A notification restriction part (27) forbids a notification unit (40) to give notice of the arrival direction of the other vehicle, when it can be considered that the reflection distance-correlation value has not fluctuated for a predetermined time period or longer. Thereby, frequency that the driver is notified of the arrival directions of the other vehicle falsely recognized due to a reflection of the reflected wave of the radar sensor with a wall of shielding is decreased.
