Abstract
A solar sensor for a vehicle that is incorporated as part of the vehicle climate control system is disclosed. The solar sensor include a photo diode assembly including a sensing surface. The photo diode assembly is mounted on a horizontally extending portion of a dashboard of a vehicle with the sensing surface oriented substantially parallel to the plane that an occupant'"'"'s body lies within when seated in the vehicle. The sensing surface is preferably oriented within a range of between about 16° and 40° above horizontal toward the front of a vehicle. Optimally, the sensing surface is oriented at an angle of 28° above horizontal relative to the front of the vehicle. The photo diode assembly includes a housing having a base surface mounted to the dashboard that is configured to hold the sensing surface of the photo diode in the desired angular orientation. The solar sensor is preferably concealed by a portion of the dashboard between the instrument panel and the windshield so that it is concealed from the line of sight of the front seat occupants.
