Abstract

A method of controlling a heating element in thermal communication with a rear window of a vehicle comprises: with a vehicle being in an external environment and comprising a rear window and a heating element in thermal communication with the rear window, a controller in communication with the heating element, the controller including a Pre-established Predictive Activation Model setting forth rules governing activation of the heating element as a function of data relating to Certain Identifiable Conditions, and a user interface configured to allow the heating element to be manually activated or deactivated; collecting data relating to the Certain Identifiable Conditions; 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 heating element; and automatically activating the heating element.

First claim

What is claimed is:

1. A method of controlling a heating element in thermal communication with a rear window of a vehicle comprising:
with a vehicle in an external environment, the vehicle comprising:
a rear window and a heating element in thermal communication with the rear window;
a controller in communication with the heating element, the controller including a Pre-established Predictive Activation Model stored in memory setting forth rules governing activation of the heating element as a function of data relating to Certain Identifiable Conditions; and
a user interface configured to allow the heating element to be manually activated or deactivated;

collecting data relating to the Certain Identifiable Conditions;
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 heating element; and
automatically activating the heating element;
wherein, the Pre-established Predictive Activation Model was formed pursuant to an analysis of input data related to the Certain Identifiable Conditions collected from other vehicles that existed when users of the other vehicles manually activated or deactivated a heating element to heat a rear windshield of those other vehicles;
wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Condition: whether a speed of an engine of the vehicle is above a certain value.

2. The method of claim 1 ,
wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the further following Certain Identifiable Conditions: a time of day; and a temperature within an interior of the vehicle.

3. The method of claim 1 ,
wherein, when a time of the day is a morning time, the controller activates the heating element pursuant to the rules of the Pre-established Predictive Activation Model as a function of data related to at least one other of the Certain Identifiable Conditions excluding the time of the day.

4. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to initially automatically activate the heating element is further a function of: a temperature within an interior of the vehicle being below a certain temperature, an air conditioning function having been activated, it being not a morning time, and an accelerator pedal being depressed greater than a certain percentage.

5. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to initially automatically activate the heating element is further a function of: a time of day being a morning time, a temperature of the external environment; whether there is sufficient moisture on a front windshield of the vehicle so as to cause activation of automatically activated wipers to wipe the front windshield; and a difference in temperature between a temperature within an interior of the vehicle and the temperature of the external environment.

6. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predicative Activation Model so as to initially automatically activate the heating element is further a function of: (i) whether there is sufficient moisture on a front windshield of the vehicle so as to cause activation of automatically activated wipers to wipe the front windshield, and (ii) a temperature of the external environment being greater than 15.556° C. or a difference in temperature between a temperature within an interior of the vehicle and the temperature of the external environment being greater than 5.6° C.

7. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predicative Activation Model so as to initially automatically activate the heating element is further a function of: (i) whether there is insufficient moisture on a front windshield of the vehicle to cause activation of automatically activated wipers to wipe the front windshield, (ii) an air recirculation setting being activated; (iii) a temperature of the external environment being less than a first certain temperature; (iv) an air conditioning setting being activated, (v) an accelerator pedal being depressed at least a certain percentage; and (vi) the temperature of the external environment being greater than a second certain temperature that is less than the first certain temperature.

8. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predicative Activation Model so as to initially automatically activate the heating element is further a function of: a temperature in an interior of the vehicle being below a certain temperature.

9. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predicative Activation Model so as to initially automatically activate the heating element is further a function of a time of day being within a certain period of time.

10. The method of claim 1 ,
wherein, whether the collected data satisfies the rules of the Pre-established Predicative Activation Model so as to initially automatically activate the heating element is further a function of: (i) a blower of the vehicle blowing heated air into an interior of the vehicle with a high blower speed; and (ii) a difference in temperature between a temperature within the interior of the vehicle and a temperature of the external environment being within a certain range.

11. The method of claim 1 further comprising:
the data relating to the Certain Identifiable Conditions collected after initially automatically activating the heating element satisfies the rules of the Pre-established Predictive Activation Model for deactivation of the heating element; and
automatically deactivating the heating element pursuant to the Pre-established Predictive Activation Model, after initially automatically activating the heating element pursuant to the Pre-established Predictive Activation Model.

12. The method of claim 11 further comprising:
the data relating to the Certain Identifiable Conditions collected after deactivating the heating element again satisfies the rules for activation pursuant to the Pre-established Predictive Activation Model; and
automatically reactivating the heating element pursuant to the Pre-established Predictive Activation Model, after automatically deactivating the heating element pursuant to the Pre-established Predictive Activation Model.

13. The method of claim 12 further comprising:
an occupant of the vehicle manually deactivating the heating element via the user interface.

14. The method of claim 13 further comprising:
upon the occupant manually deactivating the heating element via the user interface, recalibrating the Pre-established Predictive Activation Model into a new predictive activation model accounting for the collected data relating to the Certain Identifiable Conditions existing when the occupant manually deactivated the heating element and establishing new rules for activation and/or deactivation of the heating element.

15. The method of claim 14 further comprising:
the occupant manually activating the heating element via the user interface.

16. The method of claim 15 further comprising:
upon the occupant manually activating the heating element via th
