AUTOMATIC SUN VISOR DEVICE
First Claim
1. An automatic sun visor device including a sun visor body for blocking incident light entering a passenger compartment from the exterior and a driving means for moving the sun visor body, wherein the sun visor body is movable between a retracted position at which the sun visor body is retracted into the passenger compartment and a projected position at which the sun visor body is most projected from the retracted position, the device comprising:
- an incident light detecting means for detecting incident intensity and incident angle of the incident light;
a position detecting means for detecting the present position of the sun visor body; and
a controller for controlling movement of the sun visor body with the driving means, wherein;
the controller moves the sun visor body toward a target position that is set based on the incident angle when the incident intensity is in a high illuminance range that is above a predetermined value;
the controller moves the sun visor body toward the retracted position when the incident intensity is in a low illuminance range that is below the predetermined value;
the controller sets an intermediate illuminance range between a first threshold for determining whether or not the incident intensity is in the low illuminance range and a second threshold for determining whether or not the incident intensity is in the high illuminance range; and
the controller moves the sun visor body toward the target position after the target position is continuously set closer to the retracted position or the projected position than the present position for a predetermined time when the incident intensity is in the intermediate illuminance range.

Abstract
An incident intensity L is categorized into a low illuminance range A1 for immediately moving a sun visor body toward a retracted position, a high illuminance range A2 for immediately moving the sun visor body in a target direction set based on an incident angle, and an intermediate illuminance range A3 set between the two regions A1 and A2. When the incident intensity is in the region A3 and after the target position is continuously set closer to the retracted position or the projected position than the present position for a predetermined time, the sun visor body moves toward the target position. That is, there is a range between an illuminance threshold L1 for immediately moving the sun visor body toward the retracted position and an illuminance threshold L2 for immediately moving the sun visor body in the target direction based on the incident angle.
