Abstract:
1. A vehicle sun visor apparatus, comprising: a light blocking device, which has a sun visor main body provided on a vehicle to block incident light; a light receiving sensor, which outputs an incident light detection signal for specifying the incident angle of the incident light; and a control device, which specifies the incident angle of the incident light based on the incident light detection signal and performs a light blocking control to block the incident light with the light blocking device, wherein the control device stores a reference eye position of an occupant of the vehicle, and wherein the control device estimates, as an eye position of the occupant, the intersection between a straight line that passes through the reference eye position and extends along the vertical direction of the vehicle and a straight line that passes through the distal end position of the sun visor main body arranged at a position appropriate for shielding the occupant from light and is inclined by the same angle as the incident angle specified by the control device, and performs the light blocking control in accordance with the estimated eye position.
