[0023] Further advantages and details are revealed in the following description of exemplary embodiments. These show: Fig. 1 an embodiment of a partial interior view of a motor vehicle with a temperature adjustment device, Fig. 2 the temperature adjustment device of the motor vehicle according to Fig. 1 in enlarged view, Fig. 3 the motor vehicle according to Fig. 1 and the temperature adjustment device according to Fig. 2 in a detailed schematic diagram, Fig. 4 the temperature adjustment device according to Fig. 2 if the passenger seat is not occupied, Fig. 5 the temperature adjustment device according to Fig. 2 after installation in a motor vehicle without seat heating and Fig. 6 the temperature adjustment device according to Fig. 2 after installation in a motor vehicle with a 1-zone Climatronic.

[0024] Fig. 1 shows an embodiment of a partial interior view of a motor vehicle 1. The motor vehicle 1 comprises an instrument cluster 3 arranged in front of a steering wheel 2 as well as a display and operating device 4 in a center console of the motor vehicle 1. In addition, the motor vehicle 1 comprises operating elements 5 and 6 arranged in the spokes of the steering wheel 2, which are designed as cross rocker switches. In addition, the motor vehicle 1 comprises a temperature adjustment device 7 designated by reference numeral 7, which is shown enlarged in Fig. 2 is shown.

[0025] The temperature adjustment device 7 comprises a display 15 with a transparent touchscreen 16 arranged above it. Furthermore, the temperature adjustment device 7 comprises a rotary knob 11 for adjusting a temperature in the motor vehicle 1. Furthermore, the temperature adjustment device 7 comprises a rotary knob 12, which, depending on the equipment of the motor vehicle 1, is used either to adjust a temperature in the motor vehicle 1 or to adjust ventilation. The rotary knobs 11, 12 each have an illumination device 110, 120, wherein it is advantageously provided that a color dependent on the operation of the respective rotary knob 11, 12 can be displayed by means of the respective illumination device 110, 120.

[0026] In addition, the temperature adjustment device 7 comprises a hard key 21 for switching a windshield heater on and off. The temperature adjustment device 7 further comprises a hard key 22 for switching a rear window heater on and off, a hard key 23 for switching an automatic climate control system 51 of the motor vehicle 1 on and off, and a hard key 24 for switching the display 15 on and off. Furthermore, a proximity sensor 25 is provided for detecting the approach of an operator's hand to the temperature adjustment device 7.

[0027] Fig. Figure 3 shows the motor vehicle 1 and the temperature adjustment device 7 in an exemplary schematic diagram. The temperature adjustment device 7 comprises a housing 30 and a controller 31, which is integrated into the housing 30 together with the rotary knobs 11 and 12, the hard keys 21, 22, 23, and 24, the proximity sensor 25, the display 15, and the touchscreen 16. The controller 31 comprises a CAN bus interface 32 and another bus interface 33, by means of which the controller 31 is connected to the automatic climate control system 51 of the motor vehicle 1 via a data line 50.

[0028] The controller 31 is connected to a CAN bus 40 of the motor vehicle 1 via the CAN bus interface 32. The controller 31 is connected, for example, to a passenger seat 41 of the motor vehicle 1 or to a seat occupancy sensor 42 of the passenger seat 41 via the CAN bus 40. For example, a seat heater of the passenger seat 41 can be switched on and off or adjusted using the temperature adjustment device 7. Furthermore, a seat occupancy signal for the passenger seat 41 can be transmitted from the seat occupancy sensor 42 to the controller 31 via the CAN bus 40. The display and operating device 4, a navigation system, and an infotainment system can also be connected to the CAN bus 40.

[0029] The controller 31 serves in particular to control the display 15 and the optional lighting devices 110 and 120, to evaluate touches on the touchscreen 16, to evaluate an output signal of the proximity sensor 25, to detect operating actions performed by means of the rotary knobs 11 and 12 or the hard keys 21, 22, 23 and 24, and to identify devices connected to the controller 31. For example, the controller 31 can determine whether an automatic climate control system 51 is provided and what type of automatic climate control system 51 is provided. Depending on this information, the display 15 is set and a touch on the touchscreen 16 is evaluated. The functionality of the controller 31 is explained below using examples that are shown in the Fig. 4, Fig. 5 and Fig. 6 are explained in more detail by way of example.

[0030] In the Fig. In the embodiment shown in Figure 2, the automatic climate control system 51 in the motor vehicle 1 is implemented as a so-called 2-zone Climatronic. Furthermore, it is provided that in the Fig. 2, the motor vehicle 1 has a seat heater for both the driver's seat and the passenger seat 41. In addition, the passenger seat 41 is occupied by a passenger. In the embodiment shown in Fig. In the exemplary embodiment shown in Figure 2, the display 15 shows a control element 71 for operating the seat heating of the driver's seat, a control element 72 for operating the seat heating of the front passenger seat 41, and a control element 73 for adjusting the ventilation. The seat heating of the driver's seat can be adjusted by touching the touchscreen 16 in the area of ​​the control element 71. The seat heating of the front passenger seat 41 can be adjusted by touching the touchscreen 16 in the area of ​​the control element 72. The ventilation can be adjusted by touching the touchscreen 16 in the area of ​​the control element 73. In the exemplary embodiment shown, the temperature in the first climate zone is regulated by means of the rotary knob 11 and the temperature in the second climate zone is regulated by means of the rotary knob 12.

[0031] If the passenger gets out, the control 31 automatically changes the display shown on the display 15, as shown in Fig. 4. The control element 72 is no longer shown. Instead, the control element 73 for adjusting the ventilation is replaced by an enlarged control element 73A for adjusting the ventilation. The ventilation in the motor vehicle 1 can be adjusted by touching the touchscreen 16 in the area of ​​the control element 73A.

[0032] If the temperature adjustment device 7 is not installed in the motor vehicle 1, but in a comparable motor vehicle, but without seat heating, this is automatically detected by the control 31 and the display is changed in a different way, as shown in Fig. 5. The display 15 is controlled in such a way that the control elements 71 and 72 are not displayed. Furthermore, the control element 73 is replaced by an enlarged control element 73B for adjusting the ventilation of the motor vehicle. The ventilation in the motor vehicle 1 can be adjusted by touching the touchscreen 16 in the area of ​​the control element 73B.

[0033] If the temperature adjustment device 7 is not installed in the motor vehicle 1, but in a motor vehicle that does not have a 2-zone Climatronic, but only a 1-zone Climatronic, this is automatically detected by the control 31 and the display 15 is controlled accordingly, as is shown by way of example in Fig. 6. In addition, operation of the rotary knob 12 is interpreted differently. In the embodiment according to Fig. 6, the rotary knob 12 is now used to adjust the ventilation, which in this exemplary embodiment of a motor vehicle with a 1-zone Climatronic is no longer adjusted via the touchscreen 16, but rather via the rotary knob 12. Accordingly, the display 15 does not display a control element corresponding to the control elements 73, 73A, or 73B. Instead, a control element 74 is displayed, whereby touching the touchscreen 16 in the area of ​​the control element 74 calls up a menu for setting functions.

[0034] In the Fig.In the embodiment illustrated in Figure 6, the motor vehicle has a seat heater for the driver's seat and for the front passenger seat. Therefore, the temperature adjustment device 7 displays a control element 71A that is correspondingly larger than the control element 71 and a control element 72A that is correspondingly larger than the control element 72. The driver's seat heater can be adjusted by touching the touchscreen 16 in the area of ​​the control element 71A. The front passenger seat heater can be adjusted by touching the touchscreen 16 in the area of ​​the control element 72A.
