Obstacle detecting device
First Claim
1. An obstacle detecting device comprising:
- a distance measuring sensor arranged adjacent to a rotation axis of a door of a vehicle, the sensor measuring a distance to an object in a direction corresponding to a scanning angle by scanning a scanning plane;
a memory to storea standard angle defined when the sensor is mounted at a normal position, anda comparison distance defined between a mounting position of the sensor and an end of the door in the direction corresponding to the scanning angle;
an initializing portion to obtain a distance-shortest scanning angle defined by a shortest value of the measured distance;
a correcting portion to correct the scanning angle, when the distance-shortest scanning angle is different from the standard angle; and
an object determining portion to determine the object to be an obstacle having a possibility to contact with the door, when the measured distance is equal to or shorter than a corrected comparison distance corresponding to the corrected scanning angle.

Abstract
A distance measuring sensor is arranged to a vehicle door, and measures a distance to an object in a direction corresponding to a scanning angle. A memory stores a standard angle and a comparison distance corresponding to the scanning angle. A distance-shortest scanning angle is defined by the shortest value of the measured distance. When the distance-shortest scanning angle is different from the standard angle, the scanning angle is corrected. The object is determined to be an obstacle having a possibility to contact with the door, when the measured distance is equal to or shorter than a corrected comparison distance corresponding to the corrected scanning angle.
