Vehicle door opening angle control system
First Claim
Patent Images
1. A vehicle door opening angle control system comprising:
- a laser sensor mounted on a vehicle door near a pivot axis of a vehicle door to project a laser light to scan a plane oriented'"'"' in an opening direction of the vehicle door and receive a reflected light reflected by an obstacle;
a check section that checks whether the obstacle, which the vehicle door is likely to touch, is present in the door opening direction based on projection and reception of the laser light by the laser sensor; and
an opening angle limit section that limits an opening angle of the vehicle door in case the check section determines that the obstacle is present,wherein the check section determines that the obstacle is present in case that the laser sensor receives no laser light in excess of a predetermined intensity in response to projection of the laser light in a downward direction relative to a mounting position of the laser sensor.

Abstract
A laser sensor projects laser light in the downward direction. If the laser sensor does not receive any laser light reflected by an obstacle or the ground, it is determined that the obstacle is present in the direction of projection of the laser light. It is thus possible to detect the presence of the obstacle, which will at least affect the opening of the vehicle door.
