Abstract
A vehicle shading system for shading an interior of a vehicle. The vehicle shading system includes a plurality of windows located on the vehicle. Each window has a transmission control material which changes from transparent to opaque upon an application of an electric current to the transmission control material. The system also includes a controller for controlling the application of the electric current to the transmission control material. In addition, the system includes a power source providing the electric current to the transmission control material when commanded by the controller. Each window is changed from transparent to opaque when commanded by the controller by applying the electric current from the power source to the transmission control material, thereby shading the interior of the vehicle. The system may optionally include sensors to detect if the engine is off, a temperature sensor to determine if the interior temperature of the vehicle is above a specified temperature and a daylight sensor to detect if it is daylight. One or more of these sensors may be utilized to determine if the controller may command an activation of the shading system.
