1. A vehicle comprising:
a system configured to supply air to a cabin of the vehicle at a target discharge temperature;
one or more solar sensors configured to sense a solar radiation on the cabin;
one or more temperature sensors configured to sense air within the cabin; and
a controller coupled to the system, the one or more solar sensors, and the one or more temperature sensors, the controller configured to:
receive a user set temperature;
obtain a solar heat load from one or more outputs of the one or more solar sensors;
obtain a feedback temperature from one or more outputs of the one or more temperature sensors;
determine a radiation temperature corresponding to radiative heat transfer into the cabin, the radiation temperature being a function of the feedback temperature and the solar heat load;
determine a solar offset according to the solar heat load;
determine a scaled solar offset by scaling the solar offset according to a difference between the radiation temperature and the feedback temperature; and
set the target discharge temperature according to the user set temperature, the feedback temperature, and the scaled solar offset.
