Abstract

Methods, systems, and vehicles are provided for providing adaptive automatic climate control functionality for a vehicle. A sensor is configured to detect when a manual override of an automatic climate control feature of a vehicle has occurred. A processor is coupled to the sensor, and is configured to initiate the automatic climate control feature for the vehicle and adjust a calibration of the automatic climate control feature when the manual override has been detected.

Claims

1. A method, comprising:

initiating an automatic climate control feature for a vehicle using an initial set of calibration values;

detecting by a sensor, whether a manual override of the automatic climate control feature has occurred;

detecting by the sensor, a manual setting corresponding to the manual override;

calculating, using a processor coupled to the sensor, a revised set of calibration values as a weighted average between the initial set of calibration values and a second set of values corresponding to the manual setting when the manual override has been detected; and

adjusting a calibration of the automatic climate control feature using the revised set of calibration values when the manual override has been detected,

wherein;

the step of initiating the automatic climate control feature comprises automatically heating or cooling a seat of the vehicle using an initial calibration curve;

the step of detecting whether the manual override of the automatic climate control feature has occurred comprises the step of detecting whether an occupant of the vehicle has manually adjusted automatic heating or cooling of the seat; and

the step of adjusting the calibration of the automatic climate control feature further comprises updating the initial calibration curve using the revised set of calibration values, generating an updated calibration curve for use in subsequent initiation of the automatic climate control feature, wherein the updated calibration curve represents an upward or downward shift in the initial calibration curve proximate a point on the initial calibration curve in which the manual override occurred, and the step of adjusting the calibration comprises adjusting the calibration of the automatic climate control feature for subsequent automatic heating or cooling of the seat using the revised set of calibration values when the manual override has been detected.

2. The method of claim 1, further comprising:

using the revised set of calibration values instead of the initial set of calibration values for subsequent initiation of the automatic climate control feature.

3. The method of claim 1, further comprising:

detecting whether an ignition of the vehicle has been turned off; and

storing the updated calibration curve when the ignition has been turned off.

4. The method of claim 1, further comprising:

identifying a current driver of the vehicle;

wherein;

the step of initiating the automatic climate control feature comprises initiating the automatic climate control feature using a selected one of a plurality of initial calibration curves corresponding to the current driver, wherein each of the plurality of initial curves corresponds to a different driver of the vehicle, and the selected one of the plurality of initial calibration curves corresponds to the current driver; and

the step of adjusting the calibration of the automatic climate control feature further comprises updating the selected one of the plurality of initial calibration curves using the revised set of calibration values, for use in subsequent initiation of the automatic climate control feature for the current driver.

5. The method of claim 1, further comprising, subsequent to the calculation of the revised set of calibration values and the adjusting of the calibration using the revised set of calibration values:

detecting whether a second manual override of the automatic climate control feature has occurred;

detecting a second manual setting corresponding to the second manual override;

calculating a second revised set of calibration values as a weighted average between the revised set of calibration values and a third set of values corresponding to the second manual setting when the second manual override has been detected between the revised set of calibration values and the third set of values; and

adjusting the calibration of the automatic climate control feature using the second revised set of calibration values when the second manual override has been detected.

6. The method of claim 2, wherein:

the initial set of calibration values provide that the automatic climate control feature will be provided for a first amount of time for an initial initiation of the automatic climate control feature during a first ignition cycle;

the manual override of the automatic climate control feature is detected to have occurred after a second amount of time following the initial initiation of the automatic climate control feature, wherein the second amount of time is less than the first amount of time; and

the revised set of calibration values provides that the automatic control will be provided for a third amount of time in the subsequent initiation of the automatic climate control feature in a second ignition cycle, subsequent to the first ignition cycle, wherein the third amount of time is greater than the second amount of time, and wherein the third amount of time is less than the first amount of time.

7. The method of claim 6, wherein:

the manual override of the automatic climate control in the subsequent initiation of the automatic climate control feature in the second ignition cycle is detected to have occurred after a fourth amount of time following the subsequent initiation of the automatic climate control feature in the second ignition cycle, wherein the fourth amount of time is less than the third amount of time; and

a second revised set of calibration values is generated based on the manual override of the subsequent initiation of the automatic climate control feature, the second revised set of calibration values providing that the automatic control will be provided for a fifth amount of time following a second subsequent initiation use of the automatic climate control feature in a third ignition cycle that is subsequent to the second ignition cycle, wherein the fifth amount of time is greater than the fourth amount of time, and wherein the fifth amount of time is less than the third amount of time.

8. A system comprising:

a sensor configured to;

detect when a manual override of an automatic climate control feature of a vehicle has occurred; and

detect a manual setting corresponding to the manual override; and

a processor coupled to the sensor and configured to;

initiate the automatic climate control feature for the vehicle using an initial set of calibration values;

calculate a revised set of calibration values as a weighted average between the initial set of calibration values and a second set of values corresponding to the manual setting when the manual override has been detected; and

adjust a calibration of the automatic climate control feature using the revised set of calibration values when the manual override has been detected;

wherein;

the processor is configured to;

facilitate automatically heating or cooling a seat of the vehicle using an initial calibration curve; and

update the initial calibration curve using the revised set of calibration values, generating an updated calibration curve for use in subsequent initiation of the automatic climate control feature, wherein the updated calibration curve represents an upward or downward shift in the initial calibration curve proximate a point on the initial calibration curve in which the manual override occurred;

the sensor is configured to detect whether an occupant of the vehicle has manually adjusted automatic heating or cooling of the seat; and

the processor is further configured to facilitate subsequent automatic heating or cooling of the seat using the revised set of calibration values when the manual override has been detected.
