ABSTRACT:
An obstacle detection device for a vehicle notifies the driver of an obstacle approaching rapidly in the rear side by sound when a detected velocity of the obstacle relative to the vehicle is larger than a threshold velocity. It does not notify the driver of the obstacle by sound when the detected relative velocity is smaller than the threshold velocity.
