Intelligent controller providing time to target state

摘要

The current application is directed to intelligent controllers that continuously, periodically, or intermittently calculate and display the time remaining until a control task is projected to be completed by the intelligent controller. In general, the intelligent controller employs multiple different models for the time behavior of one or more parameters or characteristics within a region or volume affected by one or more devices, systems, or other entities controlled by the intelligent controller. The intelligent controller collects data, over time, from which the models are constructed and uses the models to predict the time remaining until one or more characteristics or parameters of the region or volume reaches one or more specified values as a result of intelligent controller control of one or more devices, systems, or other entities.

1. A method of calculating a time-to-temperature estimate for a thermostat controlling an HVAC system, the method comprising:
receiving a first temperature representing a current temperature of an enclosure; receiving a second temperature representing a target temperature of the enclosure; computing a first component of an estimated time representing an estimated time to transition the temperature in the enclosure from the first temperature to the second temperature by the HVAC system, wherein the first component is computed based on:
a plurality of historical time and temperature values recorded from one or more previous temperature change cycles of the enclosure; andat least one external factor selected from a group consisting of: an outside temperature, an outside sunlight amount, an outside wind velocity, and a time of day; computing second component of the estimated time based on a current trajectory of time and temperature values as the enclosure transitions from the first temperature to the second temperature; computing the estimated time based on the first component of the estimated time and the second component of the estimated time; and causing the estimated time to be displayed on a display device.
