Abstract

A method of controlling a temperature altering element within a seating assembly of a vehicle comprising: presenting a vehicle including a seating assembly including a temperature altering element, a controller in communication with the temperature altering element, the controller including a Pre-established Predictive Activation Model setting forth rules governing the activation of the temperature altering element as a function of data relating to Certain Identifiable Conditions, and a user interface configured to allow the temperature altering element to be manually activated or deactivated; occupying the seating assembly with a first occupant; collecting data relating to the Certain Identifiable Conditions while the first occupant is occupying the seating assembly; determining, by comparing the collected data to the rules of the Pre-established Predictive Activation Model, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to activate the temperature altering element; and activating the temperature altering element.

First claim

What is claimed is:

1. A method of controlling a temperature altering element within a seating assembly of a vehicle comprising:
with the temperature altering element configured to impart heating or cooling to an occupant of the seating assembly within which the temperature altering element is disposed, and with the vehicle further comprising:
a controller in communication with the temperature altering element, the controller including a Pre-established Predictive Activation Model setting forth rules governing activation of the temperature altering element as a function of data relating to Certain Identifiable Conditions; and
a user interface configured to allow the temperature altering element to be manually activated or deactivated;

collecting data relating to the Certain Identifiable Conditions while a first occupant is occupying the seating assembly;
determining, by comparing the collected data to the rules of the Pre-established Predictive Activation Model, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to initially automatically activate the temperature altering element; and
automatically activating the temperature altering element;
wherein, the rules of the Pre-established Predictive Activation Model are a function of at least one of the following Certain Identifiable Conditions: (i) time of day; (ii) engine speed; (iii) vehicle speed; (iv) whether windshield wipers have been activated; (v) level at which a climate control system in the vehicle is blowing air; (vi) whether air conditioning has been activated; (vii) whether a rear window defrost has been activated.

2. The method of claim 1 ,
wherein, the Pre-established Predictive Activation Model was formed pursuant to a classification and regression tree analysis of input data related to the Certain Identifiable Conditions collected from other operators of other vehicles.

3. The method of claim 1 ,
wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Conditions: ambient temperature; temperature set point for an interior of the vehicle; time of day; whether the first occupant has requested the vehicle to heat the interior with a blower at a certain blower speed; temperature of the interior of the vehicle; and temperature differential between the ambient temperature and the in-vehicle temperature.

4. The method of claim 3 ,
wherein, the ambient temperature is greater than a certain temperature, and the controller automatically activates the temperature altering element pursuant to the Pre-established Predictive Activation Model as a function of the ambient temperature being greater than the certain temperature and data relating to at least one other of the Certain Identifiable Conditions excluding the ambient temperature.

5. The method of claim 1 ,
wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Conditions: whether windshield wipers have been activated; whether air conditioning has been activated; temperature set point for an interior of the vehicle; ambient temperature; level at which a climate control system in the vehicle is blowing air; engine speed; vehicle speed; and in-vehicle temperature.

6. The method of claim 5 ,
wherein, windshield wipers are not activated, and the controller automatically activates the temperature altering element pursuant to the Pre-established Predictive Activation Model as a function of data relating to the windshield wipers not being activated and at least one other of the Certain Identifiable Conditions excluding whether windshield wipers have been activated.

7. The method of claim 1 ,
wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Conditions: in-vehicle temperature; ambient temperature; level at which a climate control system in the vehicle is blowing air; whether a rear window defrost has been activated; vehicle speed; whether air conditioning has been activated; engine speed; and whether windshield wipers have been activated.

8. The method of claim 7 ,
wherein, in-vehicle temperature is greater than a certain temperature, and the controller automatically activates the temperature altering element to impart cooling pursuant to the Pre-established Predictive Activation Model as a function of the in-vehicle temperature being greater than the certain temperature and data relating to at least one other of the Certain Identifiable Conditions excluding in-vehicle temperature.

9. The method of claim 1 ,
wherein, the Pre-established Predictive Activation Model establishes rules for activation of the temperature altering element to provide cooling and the rules are a function of data related to at least the following Certain Identifiable Conditions: ambient temperature; in-vehicle temperature; whether a rear window defrost has been activated; and a temperature set point for an interior of the vehicle;
wherein, the ambient temperature is less than a certain temperature and the in-vehicle temperature is greater than another certain temperature; and
wherein, the controller automatically activates the temperature altering element to impart cooling pursuant to the rules of the Pre-established Predictive Activation Model as a function of the ambient temperature being less than the certain temperature, the in-vehicle temperature being greater than the other certain temperature, and data relating to at least one other of the Certain Identifiable Conditions including vehicle speed.

10. The method of claim 1 further comprising:
automatically deactivating the temperature altering element pursuant to the Pre-established Predictive Activation Model, after initially automatically activating the temperature altering element pursuant to the Pre-established Predictive Activation Model, the collected data relating to the Certain Identifiable Conditions collected after initially automatically activating the temperature altering element satisfying the rules of the Pre-established Predictive Activation Model for deactivation of the temperature altering element.

11. The method of claim 10 further comprising:
automatically reactivating the temperature altering element pursuant to the Pre-established Predictive Activation Model, after automatically deactivating the temperature altering element pursuant to the Pre-established Predictive Activation Model, the collected data relating to the Certain Identifiable Conditions collected after deactivating the temperature altering element again satisfying the rules for activation pursuant to the Pre-established Predictive Activation Model.

12. The method of claim 11 further comprising:
after the first occupant manually deactivates the temperature altering element via the user interface, recalibrating the Pre-established Predictive Activation Model into a new predictive activation model accounting for the collected data relative to the Certain Identifiable Conditions existing when the occupant manually deactivated the temperature altering element and establishing new rules for activation or deactivation of the temperature altering element.

13. The method of claim 12 further comprising:
after the first occupant manually activates the temperature altering element via the user interface, recalibrating the new predictive activation model into a newer predictive activation model accounting for the collected data relative to the Certain Identifiable Conditions existing when the occupant manually activated the
