Patent ID: 7568751

Claim:
An automatic sun visor device including a sun visor body for blocking incident light entering a passenger compartment from the exterior and a driving device 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 frontward from the retracted position, the device comprising: an incident light detector for detecting incident intensity and incident angle of the incident light; a position detector for detecting a position of the sun visor body; and a controller for controlling movement of the sun visor body with the driving device, 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 position of the sun visor body for a predetermined time when the incident intensity is in the intermediate illuminance range.
