Display control system preventing spoofing of vehicle ambient light level

A vehicle comprising:

• a global positioning system configured to determine a location of the vehicle;
• an ambient light sensor configured to generate a measured ambient light level in the vehicle;
• a passenger display;
• a passenger display control module including:
• a solar position determining module configured to determine a position of the sun relative to the location of the vehicle, a date, and a time of day;
• an ambient light estimating module configured to estimate an ambient light level in response to the position of the sun;
• a brightness control module configured to:
• set a brightness level of the passenger display in response the ambient light level;
• when the brightness level of the passenger display corresponds to daytime, selectively detect ambient light spoofing based on a difference between the measured ambient light level and the estimated ambient light level;
• and
• selectively override the brightness level of the passenger display in response to detecting the ambient light spoofing.

• wherein the passenger display control module is configured to set a viewing mode of the passenger display to one of a private viewing mode and a shared viewing mode, and
• wherein the passenger display control module is configured to select the viewing mode in response to a selected type of content output to the passenger display.
