PROBLEM TO BE SOLVED: To accurately notify a driver of a risk due to an obstacle at the rear side of a self vehicle, and to improve safety in an obstacle detection device.SOLUTION: An obstacle detection device includes a detecting direction changing unit 5 for changing the detecting direction of an obstacle detection sensor 3 which detects an obstacle at the rear side of a self vehicle in accordance with a rudder angle of a steering wheel of the self vehicle. Thus, it is possible to set a detection range of the obstacle by the sensor to a desired detection range corresponding to the rudder angle of the steering wheel of the self vehicle, and to accurately notify a driver of a risk due to the obstacle at the rear side of the self vehicle to increase safety. Also, a degree-of-risk determination unit 6 determines the degree of a risk on the basis of not only a distance from the self vehicle to the obstacle measured by a distance measurement unit 2 but also directional indicator information showing which of right and left directional indicators 11 the self vehicle is lighting. Thus, the degree-of-risk determination unit 6 is able to determine the degree of a risk under the consideration of the fact that a driver (self vehicle) is trying to enter the next lane. |
