OBSTACLE DETECTION DEVICE, METHOD AND PROGRAM
To stop a door immediately before it collides with an obstacle and avoid collision with the obstacle in various situations.SOLUTION: An obstacle detection device according to an embodiment comprises an ultrasonic sensor signal processing part that detects at least a distance among a distance to an obstacle and a shape of the obstacle based on an output from an ultrasonic sensor that detects the distance to the obstacle within a predetermined detection range with ultrasonic waves and is arranged on a door of a vehicle, a camera image processing part that detects the distance to the obstacle and the shape of the obstacle based on an output from a camera mounted on the vehicle imaging an area including a trajectory range when the door of the vehicle is open and the detection range of the ultrasonic sensor, and a controller that conducts door opening motion control based on the detection result of the ultrasonic sensor signal processing part and the detection result of the camera image processing part.SELECTED DRAWING: Figure 1
【課題】障害物に衝突する直前でドアを停止させたり、様々な状況において障害物への衝突を回避したりする。【解決手段】実施形態の障害物検出装置は、超音波により所定の検出範囲内の障害物までの距離を検出する車両のドアに配置された超音波センサの出力に基づいて、障害物までの距離及び障害物の形状のうち、少なくとも距離を検出する超音波センサ信号処理部と、車両のドアの開時の軌跡範囲及び超音波センサの検出範囲を含む領域を撮像する車両のカメラの出力に基づいて、障害物までの距離及び障害物の形状を検出するカメラ画像処理部と、超音波センサ信号処理部の検出結果及びカメラ画像処理部の検出結果に基づいて、ドアの開動作制御を行うコントローラと、を備える。【選択図】図１
