Development, design and optimization of environmental control systems for passenger vehicles is increasingly being accomplished through the use of computer simulation models. These tools provide the capability to create a virtual test trip wherein the conditions in the passenger compartment can be predicted for a wide variety of external environments and driving conditions. Subjective thermal comfort response was simulated using a two-part model: 1) a physical model of the human body and its interaction with the surrounding environment and 2) a subjective model relating the thermal comfort to the physical variables calculated for the human body. The physical model allows the highly non-uniform and transient conditions that can occur in a vehicle to be explicitly included in the simulation. The subjective model focused on the rapid environmental changes associated with winter warm-up and summer cool-down transients. Experimental thermal comfort data were collected with human subjects in a simulated vehicle passenger compartment with a variety of warm-up and cool-down conditions. The data were used to determine empirical coefficients relating subjective responses to the physiological variables. Once completed, the combined model was validated with an independent set of data collected on subjects in actual vehicles.
