Abstract: A method for controlling the temperature of two or more zones inside a vehicle using an HVAC system. In one aspect, a method for controlling temperature inside a vehicle is provided that comprises determining a power required to control the temperature of a first zone of the vehicle and determining a discharge air temperature for one of the first zone and a second zone of the vehicle based on a mass transfer between the first zone and a second zone of the vehicle. In another aspect, a method for controlling temperature inside a vehicle is provided that comprises determining a power required for a first zone and a third zone of the vehicle, determining a mass transfer in a second zone of the vehicle, and determining a discharge temperature for one of the first zone, second zone, and third zone of the vehicle based on a mass transfer between two zones of the vehicle.

Abstract: An air conditioner for an automobile having a passenger compartment comprising is provided, including an air control system to control a property of air entering the passenger compartment, a manual setting member through which the property of the air is manually controlled, and a control system that automatically controls the property of the air based on a control characteristic. The control system updates the control characteristic based on an input from the manual setting member and based on a variable learning rate. The variable learning rate may be based on a time value measured between a first adjustment of the manual setting member and a second adjustment of the manual setting member and based on a magnitude of the second adjustment of the manual setting member. The property of the air entering the passenger compartment may be volumetric flow rate or temperature.
