Abstract
A temperature control method and apparatus responsive to various control conditions to determine the desired amount of temperature control to cause the compartment temperature of a vehicle to approach a desired value. They comprise a first step of producing a first control condition in response to the amount of light incident to the vehicle compartment and a second step of producing a second control condition in response to the amount of heat radiation incident to the vehicle compartment, and a third step whereby the second control condition is adjusted by the first control condition so as to compensate the amount of temperature control in accordance with the adjusted control condition.
