Abstract
A motor vehicle automatic climate control determines the heating or cooling influence of the deep mass components of the cabin and compensates the climate control to offset the thermal effects of the deep mass components on the cabin air temperature. The deep mass temperature is either measured or estimated by modeling, and combined with an estimate of the thermal resistance between the deep mass components and the cabin air to determine the heating or cooling power required to offset the deep mass temperature. The heating or cooling power so determined is used by a climate control algorithm to adjust the system air discharge velocity and temperature, directly compensating for the deep mass temperature effects.
Claims8
A method of operation for an automatic climate controller that develops HVAC climate control commands for regulating an air temperature in a cabin of a motor vehicle, comprising the steps of:
- measuring or estimating a temperature of deep mass components of said cabin and a temperature of the air in said cabin;
- determining a thermal transfer parameter characterizing heat transfer between said deep mass components and the air in said cabin;
- determining a heating or cooling power to be supplied to said cabin for offsetting heat transfer between said deep mass components and the air in said cabin, based on said thermal transfer parameter and the temperatures of said deep mass components and said cabin air;
- and
- adjusting said HVAC climate control commands according to the determined heating or cooling power to compensate the regulation of said cabin air temperature for heat transfer between said deep mass components and the air in said cabin.
