Abstract
The invention relates to a solar altitude detector (1) for motor vehicles comprising a shade mask (2) in which a passage opening (5) provided for permitting sunlight though is inserted, said opening creating a light structure when irradiated. A sensor array (3) comprising a plurality of individual pixels is representively arranged under the shade mask (2) such that individual sections of the light structure created by the passage opening (5) fall on the photosensitive surface of the sensor array (3) during solar radiation. Various pixels of the sensor array (3) are irradiated according to the incidence angle of the sunlight passing through the passage opening (5) such that a clear statement which refers to the incidence angle and to the incidence direction of the sunlight is possible.
