Abstract

An air-conditioning system for the passenger compartment of a motor vehicle is provided, wherein the air conditioning system has at least one operator control unit and at least two air outlets. The operator control unit has a touch-sensitive strip. The air-conditioning system is configured to perform the following: separate control of the temperature of the air which flows out of the first air outlet and the temperature of the air which flows out of the second air outlet; determination of the temperature of the air for the first and the second air outlets independently of one another, and as a function of sensed contact with the strip.

First claim

What is claimed is:

1. An air-conditioning system for a passenger compartment of a motor vehicle, the air-conditioning system comprising:
an operator control unit,
at least two air outlets,
wherein the operator control unit comprises a touch-sensitive strip, and
wherein the air-conditioning system is configured to:
detect a touch of the touch-sensitive strip by a user,
separately control temperature of air flowing out of a first air outlet and a temperature of an air flowing out of a second air outlet, and
determine a temperature of air for both the first and the second air outlets, respectively, as a function of only the detected touch of the touch-sensitive strip by the user,
wherein the determined temperature of air for the first air outlet is different than the determined temperature of air for the second air outlet.

2. The air-conditioning system according to claim 1 ,
wherein the operator control unit is configured to:
in a first area, detect a position of the touch of the touch-sensitive strip along a longitudinal dimension of the strip,
wherein the air-conditioning system is further configured to:
in response to detecting the touch in the first area of the touch-sensitive strip, setting the temperature of the air for both the first and the second air outlets as a function of only the position of the touch along the longitudinal dimension of the strip.

3. The air-conditioning system according to claim 2 ,
wherein a set temperature of air for the first air outlet is higher with respect to a desired temperature when the touch is detected in a first half of the longitudinal dimension of the strip, and
wherein a set temperature of air for the first air outlet is lower with respect to a desired temperature when the touch is detected in a second half of the longitudinal dimension of the strip.

4. The air-conditioning system according to claim 2 ,
wherein the operator control unit is further configured to:
detect a touch of a second area of the strip, the second area being arranged at a first end of the strip,
detect a touch of a third area of the strip, the third area being arranged at a second end of the strip,
wherein the air-conditioning system is further configured to:
in response to the detection of the touch of the first or the second area of the strip, change the temperature of air for the first air outlet by a value or factor assigned to the respective area, and change the temperature of air for the second air outlet by a different value or factor than the assigned value or factor,
wherein the value or factor assigned to the first area is greater than 0° C. or 1, and the value or factor assigned to the second area is lower than 0° C. or 1.

5. The air-conditioning system according to claim 3 ,
wherein the operator control unit is further configured to:
detect the touch of a second area of the strip, the second area being arranged at a first end of the strip,
detect the touch of a third area of the strip, the third area being arranged at a second end of the strip,
wherein the air-conditioning system is further configured to:
in response to the detection of the touch of the first or the second area of the strip, change the temperature of air for the first air outlet by a value or factor assigned to the respective area, and change the temperature of air for the second air outlet by a different value or factor than the assigned value or factor,
wherein the value or factor assigned to the first area is greater than 0° C. or 1, and the value or factor assigned to the second area is lower than 0° C. or 1.

6. The air-conditioning system according to claim 2 ,
wherein the touch-sensitive strip comprises individual sensor surfaces in the first area, which are arranged in a row along the longitudinal dimension of the strip.

7. The air-conditioning system according to claim 1 , wherein:
the operator control unit further comprises luminous elements arranged in a row, and
the air-conditioning system is further configured to:
activate one of more of the luminous elements such that a position of the activated luminous element or elements with respect to the longitudinal dimension of the row represents the air temperature determined for the first air outlet.

8. The air-conditioning system according to claim 7 ,
wherein the row of luminous elements is superimposed on the touch-sensitive strip at least partially in the longitudinal direction.

9. The air-conditioning system according to claim 4 , wherein:
the first area has two unconnected partial areas,
the operator control unit is further configured to:
detect a touch of the strip in a fourth area, the fourth area being arranged in the longitudinal dimension between the two partial areas of the first area,
wherein the air-conditioning system is further configured to:
in response to the detection of the touch of the fourth area of the strip, set the temperature of air for both the first and the second air outlets to the respective previously determined desired temperature.

10. A motor vehicle, comprising an air-conditioning system according to claim 1 .

11. The motor vehicle according to claim 10 , wherein the operator control unit is configured to:
in a first area, detect a position of the touch of the touch-sensitive strip along a longitudinal dimension of the strip,
wherein the air-conditioning system is further configured to:
in response to detecting the touch of the first area of the touch-sensitive strip, setting the temperature of air for both the first and the second air outlets as a function of the position of the touch along the longitudinal dimension of the strip.

12. The motor vehicle according to claim 10 , wherein a set temperature of air for the first air outlet is higher with respect to a desired temperature when the touch is detected in a first half of the longitudinal dimension of the strip, and
wherein a set temperature of air for the first air outlet is lower with respect to a desired temperature when the touch is detected in a second half of the longitudinal dimension of the strip.

13. The motor vehicle according to claim 11 , wherein the operator control unit is further configured to:
detect a touch of a second area of the strip, the second area being arranged at a first end of the strip,
detect a touch of a third area of the strip, the third area being arranged at a second end of the strip,
wherein the air-conditioning system is further configured to:
in response to the detection of the touch of the first or the second area of the strip, change the temperature of air for the first air outlet by a value or factor assigned to the respective area, and change the temperature of air for the second air outlet by a different value or factor than the assigned value or factor,
wherein the value or factor assigned to the first area is greater than 0° C. or 1, and the value or factor assigned to the second area is lower than 0° C. or 1.

14. The motor vehicle according to claim 11 , wherein the touch-sensitive strip comprises individual sensor surfaces in the first area, which are arranged in a row along the longitudinal dimension of the strip.

15. The motor vehicle according to claim 10 , wherein:
the operator control unit further comprises luminous elements arranged in a row, and
the air-conditioning system is further configured to:
activate one of more of the luminous elements such that a position of the activated luminous element or elements with respect to the longitudinal dimension of the row represents the air temperature determined for the first air outlet.
