Abstract

A method includes: sensing a current cabin temperature in a cabin of a vehicle using a cabin temperature sensor; determining a desired cabin temperature based on input received via a cabin temperature setting means; displaying an indication of the desired cabin temperature on a display in the vehicle; displaying an indication of the current cabin temperature on the display; and updating the displayed indication of the current cabin temperature in real-time when a change of the current cabin temperature is sensed. The indication of the desired cabin temperature is displayed concurrently with and in substantial proximity to the indication of the current cabin temperature.

First claim

What is claimed is:

1 . A method comprising:
sensing a current cabin temperature in a cabin of a vehicle using a cabin temperature sensor; determining a desired cabin temperature based on input received via a cabin temperature setting means; displaying an indication of the desired cabin temperature on a display in the vehicle; displaying an indication of the current cabin temperature on the display; and updating the displayed indication of the current cabin temperature in real-time when a change of the current cabin temperature is sensed, wherein the indication of the desired cabin temperature is displayed concurrently with and in substantial proximity to the indication of the current cabin temperature.

2 . The method of claim 1 , further comprising:
displaying the indication of the desired cabin temperature and the indication of the current cabin temperature according to a step-based display scheme including temperature steps displayed on the display, wherein each temperature step represents a particular temperature within a temperature range.

3 . The method of claim 2 , further comprising:
displaying the indication of the desired cabin temperature using a first indicator that corresponds to a first temperature step of the temperature steps; and displaying the indication of the current cabin temperature using a second indicator that corresponds to a second temperature step of the temperature steps.

4 . The method of claim 3 , wherein the first temperature step and the second temperature step are the same temperature step.

5 . The method of claim 3 , wherein the first indicator is a first icon and the second indicator is a second icon different from the first icon.

6 . The method of claim 2 , further comprising:
determining which temperature step of the temperature steps corresponds to the current cabin temperature based on the current cabin temperature sensed by the cabin temperature sensor, a total number of steps of the temperature steps, and a minimum and maximum temperature of the temperature range.

7 . The method of claim 6 , wherein the determining of which temperature step corresponds to the current cabin temperature is based further on a predetermined minimum and maximum temperature defining a temperature range within which the cabin of the vehicle is comfortable.

8 . The method of claim 2 , wherein each temperature step represents a particular temperature within a temperature range according to the following equation:

wherein T STEP (i) is a temperature at temperature step i, m is a total number of steps of the temperature steps, T SET,MIN is a minimum temperature in the temperature range, and T SET,MAX is a maximum temperature in the temperature range.

9 . The method of claim 1 , further comprising:
displaying the indication of the desired cabin temperature using a first numerical value; and displaying the indication of the current cabin temperature using a second numerical value.

10 . The method of claim 1 , further comprising:
determining a heating or cooling state of the vehicle; and displaying an indication of the heating or cooling state on the display, wherein the indication of the heating or cooling state is displayed concurrently with the indication of the desired cabin temperature and the indication of the current cabin temperature.

11 . The method of claim 10 , further comprising:
determining the heating or cooling state based on a position of temperature doors in the vehicle.

12 . The method of claim 10 , further comprising:
displaying the indication of the heating or cooling state using a color-based indicator.

13 . The method of claim 12 , further comprising:
updating the displayed indication of the heating or cooling state in real-time when a change of the heating or cooling state is determined by altering a color of the color-based indicator.

14 . The method of claim 12 , further comprising:
displaying the indication of the heating or cooling state according to a color-based display scheme including shades of color displayed on the display, wherein each shade of color represents a particular heating or cooling state of a plurality of predetermined heating or cooling states.

15 . The method of claim 12 , wherein an indication of a heating state is displayed using a reddish-colored indicator, and an indication of a cooling state is displayed using a bluish-colored indicator.

16 . The method of claim 10 , wherein the determined heating or cooling state substantially corresponds to one of: maximum heating, partial heating, maximum cooling, partial cooling, and neutral.

17 . The method of claim 1 , further comprising:
determining a blower state of the vehicle; and displaying an indication of the blower state on the display, wherein the blower state represents whether an air conditioning system or a heater system is active, and the indication of the blower state is displayed concurrently with the indication of the desired cabin temperature and the indication of the current cabin temperature.

18 . The method of claim 17 , further comprising:
displaying the indication of the blower state using a text-based indicator.

19 . The method of claim 1 , further comprising:
determining a desired driver-side cabin temperature based on input received via a first cabin temperature setting means; determining a desired passenger-side cabin temperatur
