Solar sensor for a vehicle
First Claim
1. A solar sensor for a vehicle, for receiving incident solar radiation transmitted through a window glass of the vehicle, whereinsaid solar sensor has a sensitivity in a wavelength band from a visible light region to a near infrared region, andsaid solar sensor has a spectral sensitivity with a sensitivity ratio within a range from 0.8 to 5.0, the sensitivity ratio being expressed as:
- (a sensitivity for a wavelength longer than 700 nm)/(a sensitivity for a wavelength shorter than 700 nm).

Abstract
By giving an attention to the fact that the difference in the transmittance of solar radiation in the visible light region is small for each type of glass, even though the type of window glass is changed, the sensitivity ratio α of a sensor element 43a in a solar sensor 43 is set to be from 0.8 to 5 so that it has a spectral sensitivity closer to the visible light region in comparison with a conventional solar sensor. By this, the variation in the deviation of the sensor outputs depending on the types of the window glass is eliminated. Thus, a target sensor output corresponding to the amount of solar radiation can be attained without being influenced by the types of the glass, even when the transmittance for the wavelengths of sun light changes depending on the types of the glass.
