Abstract
A sun protection system for a transportation vehicle has plurality of LCD zones laminated into one or more glazings of the vehicle. An occupant sensor detects an expanse of at least one occupant in the vehicle. A navigation system determines a vehicle location, a date and time value, and a heading. External and internal temperature sensors sense outside and inside temperatures. A controller generates respective drive signals for the respective LCD zones in a manual mode and in an automatic mode. The controller compares a temperature difference between the outside temperature and the inside temperature to a temperature threshold. The respective drive signals provide substantially zero attenuation if the temperature difference is less than the temperature threshold while in the automatic mode.
