Determination of sun rays inside a vehicle

A system, comprising:

• a communication device configured to obtain information as to a current angle of the sun;
• and
• a processor coupled to the communication device and configured to:
• define a ray from a point of interest inside a vehicle toward the sun using the information;
• and
• determine whether the ray intersects a transparent surface of the vehicle, for use in determining whether the point of interest is irradiated by rays of the sun when he ray intersects the transparent surface.

A vehicle comprising:

• a body;
• a drive system disposed inside the body;
• and
• a controller disposed inside the body, the controller comprising:
• a communication device configured to obtain information as to a current angle of the sun;
• and
• a processor coupled to the communication device and configured to:
• define a ray from a point of interest inside the vehicle toward the sun using the information;
• and
• determine whether the ray intersects a transparent surface of the vehicle, for use in determining whether the point of interest is irradiated by rays of the sun if the ray intersects the transparent surface.
