A comfort system is provided for a motor vehicle. A seat occupancy sensor determines whether a third row zone is occupied. At least one flow controller is provided in the floor duct for controllably supplying the conditioned airflow to at least the third row outlet. If the third row zone is occupied, then a second row outlet and the third row outlet are turned on to supply a conditioned airflow to a front seat zone, a second row zone, and the third row zone. If the third row zone is not occupied, then the third row outlet is closed off. If the second row zone is not occupied, then the second and third row outlets are closed off. If occupied, then the second row outlet is turned on until a desired comfort level is achieved in the second row zone.

1. A comfort system for a motor vehicle, wherein the vehicle includes a passenger cabin with a front seat zone, a second row zone, and a third row zone, and wherein the vehicle includes at least one seat occupancy sensor for determining at least whether the third row zone is occupied, the comfort system comprising; only one blower for driving an airflow, wherein the one blower drives the airflow to each of the front seat zone, the second row zone, and the third row zone;a heat exchanger for exchanging heat with the driven airflow and outputting a conditioned airflow;a front register for delivering at least a portion of the conditioned airflow to the front seat zone;a rear duct including a second row outlet for delivering at least a portion of the conditioned airflow to the second row zone and a third row outlet for delivering at least a portion of the conditioned airflow to the third row zone;at least one flow controller in the rear duct for controllably supplying the conditioned airflow to at least the third row outlet; anda comfort controller for coupling to the seat occupancy sensor and to the flow controller, the comfort controller configured for: detecting whether the third row zone is occupied;if the third row zone is occupied, then turning on the second row outlet and the third row outlet to supply conditioned airflow to the front seat zone, the second row zone, and the third row zone;if the third row zone is not occupied, then: closing off the third row outlet;detecting whether the second row zone is occupied;if the second row zone is not occupied, then closing off the second and third row outlets to supply conditioned airflow to only the front seat zone; andif the second row zone is occupied, then turning on the second row outlet to supply the conditioned airflow to only the front seat zone and the second row zone until a desired comfort level is achieved in the second row zone. 2. The comfort system of claim 1 including a second row flow controller and a third row flow controller, each comprising a damper selectably providing the conditioned airflow to the second row outlet and the third row outlet, respectively. 3. The comfort system of claim 2 wherein when the second row zone is occupied, then closing off the second row flow controller when the desired comfort level is achieved. 4. The comfort system of claim 1 wherein the comfort controller automatically introduces a reduction in the driven airflow in response to closing off of the second or third row outlets. 5. The comfort system of claim 1 further comprising a comfort sensor for detecting when the desired comfort level is reached. 6. The comfort system of claim 5 wherein the comfort sensor is comprised of a temperature sensor. 7. The comfort system of claim 5 wherein the comfort sensor is comprised of a remote sensor for detecting a thermal condition of an occupant. 8. The comfort system of claim 7 wherein the remote sensor is comprised of an infrared sensor. 9. The comfort system of claim 1 wherein the seat occupancy sensor includes a weight sensor for providing a weight signal to the comfort controller, and wherein the desired comfort level is set by the comfort controller in response to the weight signal. 10. The comfort system of claim 1 wherein the vehicle includes a remote start module for coupling with the comfort controller to indicate the occurrence of a remote start state of the vehicle, and wherein the comfort controller closes off the second and third row outlets in response to the remote start state. 11. The comfort system of claim 1 wherein the vehicle includes a remote start module for coupling with the comfort controller to indicate the occurrence of a remote start state of the vehicle with a chauffeur option, and wherein the comfort controller: overrides the occupancy sensor logic, turns on the second row outlet and the third row outlet, and closes off the front register in response to the chauffeur option. 12. A method for three-zone airflow control in a motor vehicle using a comfort system, wherein the vehicle includes a passenger cabin with a front seat zone, a second row zone, and a third row zone, at least one seat occupancy sensor for determining at least whether the third row zone is occupied, and a comfort system comprising: only one blower for driving an airflow, wherein the one blower drives the airflow to each of the front seat zone, the second row zone, and the third row zone; a heat exchanger for exchanging heat with the driven airflow and outputting a conditioned airflow; a front register for delivering at least a portion of the conditioned airflow to the front seat zone; a rear duct including a second row outlet for delivering at least a portion of the conditioned airflow to the second row zone, and a third row outlet for delivering at least a portion of the conditioned airflow to the third row zone; at least one flow controller in the rear duct for controllably supplying the conditioned airflow to at least the third row outlet; and a comfort controller for coupling to the seat occupancy sensor and to the flow controller; the method comprising: driving an airflow by the only one blower, wherein the blower drives the airflow past the heat exchanger;exchanging heat between the heat exchanger and the airflow to output the conditioned airflow for supplying the conditioned airflow to each of the front seat zone, the second row zone, and the third row zone;controllably blocking the conditioned airflow to each of the second row zone and the third row zone, using at least one flow controller in a duct;detecting occupancy in each of the second row and the third row by the seat occupancy sensor; andcontrolling the driven airflow using the comfort controller coupled to the seat occupancy sensor and the flow controller, whereby the method further comprises:detecting whether a third row zone is occupied; a) upon detecting the third row zone is occupied, then: opening the flow controller in the duct to a second row outlet and a third row outlet to supply conditioned airflow to the front seat zone, the second row zone, and the third row zone;b) upon detecting the third row zone is not occupied, then: closing the flow controller in the duct to the third row outlet, thereby blocking airflow to the third row outlet; anddetecting whether the second row zone is occupied; i) upon detecting the second row zone is not occupied, then: closing the flow controller in the duct to the second and third row outlets to supply conditioned airflow to only the front seat zone; andii) upon detecting the second row zone is occupied, then: opening the flow controller in the duct to the second row outlet to supply the conditioned airflow to only the front seat zone and the second row zone.
