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.
Claims20
An obstacle detection device for a vehicle, comprising:
- a distance determination means for determining a distance between the vehicle and an obstacle;
- a velocity obtainment means for obtaining velocity-related information related to velocity of the vehicle;
- and
- a notification means for notifying of the obstacle in a first method if the distance is shorter than a threshold distance, and notifying of the obstacle in a second method according to rapidness of approach of the obstacle to the vehicle which is indicated by the velocity-related information if the distance is longer than the threshold distance.
