In this way, the user is given an exclusively effect-oriented operating method for adjusting his climate, which is extremely intuitive and simple.

Description

The invention relates to a method for achieving a desired comfort setting in a motor vehicle according to the features of the preamble of patent claim 1.

For example, today's air conditioning systems in motor vehicles allow an operator only a function-related adjustment of the air conditioning. As a rule, the operator can set the intensity of the air flow, the temperature of the air or else the direction of the flowing air (air distribution) via a corresponding air conditioning operating device. Furthermore, he can activate a seat heater in stages via separate switch or, for example, a steering wheel heating on or off.

The operator must therefore today learn the effect relationship between the individual technical functions of the air conditioning (for example, temperature setting, air distribution, fan setting, selected level of seat heating, etc.) and the resulting effect on the own body or on the personal feeling and this during operation partly experimentally / iteratively determine (trial and correction).

For example, if the operator wishes to have a warmer feel on the head, he must first adjust the vents in the direction of his head, set the temperature control to a higher temperature, and if necessary also adjust the speed of the fan to a higher value.

For comparatively simple comfort requirements (eg "head a little cooler"), the operator may therefore have to perform a large number of operating steps nowadays, which may also have a disadvantageous effect on driving safety.

Of the DE 10 2008 000 405 A1 is based on a comparable problem.

In this document, an input interface for operating a plurality of parameters of an air conditioner is formed as a 3D coordinate element. The 3D coordinate element is associated with an associated coordinate system whose horizontal coordinate forms a first dimension whose vertical coordinate forms a second dimension and whose third coordinate, which is orthogonal to the first and second coordinates, forms the third dimension, wherein the three dimensions are the climate parameters air temperature , Air distribution and air flow are assigned.

In this case, it is proposed, in particular, to form the 3D coordinate element in the form of a touch-sensitive input surface, in particular as a touchscreen, to which the three-dimensional coordinate system is assigned. By moving, for example, a finger in the plane of the touchscreen and in dependence on an applied pressure strength or printing time, a combined operation or adjustment of air temperature, air distribution and air quantity is possible.

In the DE 10 2008 046 625 A1 For example, on an input interface designed as a touch-sensitive input surface, a symbol for an occupant that can be infiltrated by air with adjustable temperature and air quantity is shown, wherein the symbol has a head part, a torso area and a leg area.

Each of the climate parameters "air temperature" and "air quantity" is associated with the body zones associated vertical or horizontal Einstell-Berührungslinie, so that the two climate parameters are indeed combined on the input interface with each other, but must be set separately.

Finally, out of the DE 20 2006 003 543 U1 a touch-sensitive input surface is known on which the silhouettes of seated in seats in the interior of a motor vehicle occupants are shown. Each body area is assigned different colors (depending on the preselected actual or target temperature). At the same time, climate parameters such as air volume and air temperature can be set via the touch-sensitive input surface.

In view of the state of the art, it is desirable to develop a generic method for achieving a desired comfort setting, in particular climate control in a motor vehicle, in such a way that an even easier and more intuitive operation for the operator is made possible.

This object is achieved with the characterizing features of claim 1. Advantageous embodiments or developments of the invention can be taken from the respective subclaims.

The invention is based on a method for achieving a desired comfort setting in a motor vehicle, in particular a climate setting, wherein at least one parameter of a desired comfort setting is set or adjustable by an input or inputs of a user via an input interface.

According to the invention it is now proposed that the operation of the user is oriented to his desired, subjective effect, that when the climate changes via the input interface, only an adjustable parameter is made available to which all or at least several parameters actually involved in a desired climate setting are subordinated.

Thus, based on the parameter that can be set by the operator, all or at least a plurality of subordinate parameters or technical devices that can contribute to a desired climate change are adjusted accordingly.

The operator is thus provided an effect-oriented and no longer a function-oriented operation available. He no longer needs to learn the relationship between adjustable technical functions and his personal sense of comfort or climate, and in some cases has to determine iteratively during operation. The operation becomes more intuitive for the operator.

The input interface may preferably be designed in the form of a touch screen, so that the display of setpoints or actual values is simultaneously possible by means of the input interface. But also a division of input interface and corresponding representation of setpoint or actual values (for example, rotary / push button for input and display for display) are conceivable.

A development of the invention provides that the user via the input interface as a higher-level, adjustable parameters a qualitative parameter setting is possible.

By such a purely qualitative attitude, an effect-oriented operation of the user can best be depicted.

Thus, for example, it is conceivable that the user is only provided with the (graphical) input option "warmer" or "colder" or "more to red" or "more to blue" for changing the climate via the input interface.

Also conceivable are qualitative parameters such as "comfortable" on the one hand and "fresher" on the other.

In contrast to conventional comfort systems, where the operator must specify absolute values of one or more parameters (eg air temperature at 20 ° C, ventilation at level 2, etc.), now only the selection of such a parameter setting is required relative relationship to a default or pre-settable setting of the parameter, as an adjustable more or an adjustable less. The setting can be stepped, but also infinitely possible.

The user may not care, starting from which specific air temperature, air flow distribution or air quantity he passes on his desire to change the climate via the input interface to the system and which technical, subordinate parameters may need to be changed.

However, it can be very advantageous in this case if the user is provided with a plurality of thermal transmission paths for selection via the input interface.

For it may well be true that a particular thermal transfer path (e.g., heat convection or draft) is perceived by one operator to be convenient but unpleasant to the other operator. Thus, it is ensured by a selection of the thermal transmission paths that only those thermal transmission paths are to be involved in the realization of a desired climate, which are perceived as optimal for an operator, at least from his point of view.

But also from an energy-technical point of view, the selection or the exclusion of certain thermal transmission paths can be extremely useful.

For example, it can be very useful if the user is provided with the thermal transmission paths heat conduction, heat radiation and heat convection for selection.

It is conceivable in a further, advantageous embodiment of the invention that the selection of thermal transmission paths takes place in combination with certain body zones.

For example, the operator can specify in advance in a "Basic settings" menu that the thermal transmission path of the heat convection (drafts) should be excluded in the case of climate change requests in the header area. A climate change in the head area should therefore not by changing the amount of air, d. H. by increasing or decreasing the ventilation directed towards the head area.

It has proved to be very advantageous if the input of the user to change the climate of settings of a permanently effective automatic function is assumed. That is, the logic of an operating system or a comfort control is based on By default, predetermined or specifiable settings, so that an operator sets primarily individually desired deviations from these default settings. The automatic function preferably derives its settings from previously defined comfort parameters for certain external conditions. For example, this can be ensured by a "virtual climate model" of an individual determined empirically and stored in a suitable storage unit of an air conditioning unit.

According to this climate model, the different parts of the body can be assigned specific climate parameters that make an "average person" feel comfortable.

The individual body areas are thus assigned certain standard comfort parameters (for example air temperature, air quantity, radiation intensity), so that the operator primarily sets only individually desired deviations (local offsets) from these default values.

However, the automatic function may also derive its settings from information on an onboard comfort sensor which detects the individual condition of the operator and is located in the vicinity of the operator to measure the respective effect of an operator input.

For example, skin surface temperatures at different body areas can be measured and correlated. From this thermographic recordings can be generated, from which statements are possible, whether a person feels too warm or too cold.

Due to large individual sensory differences, however, it is provided according to a development of the invention that the default settings of the automatic function are changeable.

In this case, the change or setting of such a general comfort specification for the automatic function on a separate area of the example designed as a touchscreen input interface or at a completely different location, eg. B. via a mechanical control panel (turntable, rotary control or the like).

It is also conceivable that the operation of the user to achieve a desired comfort setting for adjusting the standard by the automatic function default comfort parameter is used, such as in the manner of a learning system with the operator inputs as an information source. Thus, the need for a "correction operation" by the user with the duration of use may decrease. For this, coupling with other sources of information regarding the identity, the clothing level or the physical activity level of the customer is expedient.

Furthermore, it is conceivable according to a development of the invention, in particular in connection with the selection of thermal transmission paths, that the operator is given the opportunity to specify in which tolerance ranges a control in the individual thermal transmission paths, preferably body part, may move to the To climate-control the operator locally and to achieve optimal overall comfort. For example, it is conceivable to stipulate that in the case of a desired, head-related climate change, the draft may only be changed by more than 20% of its initial value.

Instead of a total exclusion of a thermal transmission path so there is the possibility to weight its influence on a desired climate change. For example, via a suitable switch and / or a suitable setting menu, the influence of a specific thermal transmission path on the levels "strong", "medium", "weak" up to a complete deactivation of the respective thermal transmission path can be set.

Furthermore, it is conceivable to enable a personalized storage option of time-dependent, locally acting heating or cooling scenarios. For example, via the input interface, it can be determined that, when traveling to a specific destination, in a certain annual and at a certain time of day, an existing seat heating is initially set to a maximum and then reduced by a certain number of steps after a predetermined time. It is also conceivable a takeover by the already mentioned "learning system" whereby the input made by repeated, manual setting by the system as automatic.

According to a particularly advantageous embodiment of the invention, it is provided that the user via the input interface, the entry of one or more sites of climate change is made possible.

In this way, a very accurate, effect-oriented climate change by the user is possible, which takes into account the actual climate needs of a user to a high degree.

In this case, body parts can be selected in the invention as sites of action to give the user a quick orientation for the selection of a suitable site of action.

For example, it is possible to form the input interface as a touch screen and graphically divide the body into the body parts head, torso and legs. These body parts can then be selected by touch and there set a desired "local climate". A locally adjusted climate can be considered as a local offset to default values previously set for the entire body (global climate). If an operator desires, for example, a "warmer" climate sensation on the head and a "colder" climatic sensation on the legs than the global climate, he first selects these body parts and then sets the desired offset locally. The local offset is preferably purely qualitative, for example, as "plus" or "minus" adjustable. It is conceivable to make a local offset color coded and / or by a corresponding plus or minus sign.

Regardless of the setting option for local offsets, it may be useful if the operator has the option, if necessary, to subsequently change the global climate, ie to perform a global offset. Of course, this also affects the local offsets.

In a highly advantageous embodiment of the inventive idea, however, any areas of the body can be selected as sites of action in order to be able to provide the operator with a maximum possible flexibility of body air conditioning.

The selection of the sites of action preferably takes place graphically on the input interface embodied as a touchscreen.

Thus, for example, by touching one or more parts of the body on the touch screen, these can be graphically highlighted and also be changed via a graphically simulated slider on the touch screen with regard to their local climate setting.

As already mentioned, a change in climate settings no longer takes place quantitatively or absolutely via specific parameter values, such as a temperature preselection, but purely qualitatively.

In this context, a multi-level comfort scale is expediently specified in the operation of the user, in which the user, based on the preset default value of the automatic function, the parent parameter in two directions, ie as a more or a less of the standard value, change. Here, a seven-level comfort scale has proven to be particularly suitable.

If any areas of the body are selectable as sites of action, a displacement of such a selected area is made possible according to a very expedient development of the invention.

Such an arbitrary body region can be generated, for example, by touching a touch screen on which a graphical representation of the user or a video image of the same, at a certain point, whereupon a circular (or otherwise shaped) area graphically in the manner of a "Klimaspots "is generated on the touch screen.

This climatic rule can then be arbitrarily manipulated, placed or moved on the touch screen by means of a shift action.

By means of an appropriate control, it is now ensured that the inputs of a user entered with regard to such a shifted climate spot also really have an effect on the air conditioning components, actuators, etc. effective for the selected body area or for the selected body area.

As a further possible interaction, it is conceivable that a change in size of such a selected region is made possible after such a climate control has been generated. This can be done, for example, by a so-called pinch gesture, wherein after touching such a Klimaspots with two fingers, these pulled apart (zoom-in function) or again moved towards each other (zoom-out function). Due to this stepless adjustment an air-conditioning spot or diffuse effect is possible. For example, air vents may be changed in their spot / diffuse characteristics with respect to a selected body region. Also, the change in the emission characteristics of infrared radiators by electric motor-driven position change is conceivable.

Finally, according to a development of the invention, provision is made for a change in the effective climate setting for such a selected region to be made possible by turning the selected region.

Here too, for example, it is conceivable that such a climate control touches by means of two fingers and, for example, by a clockwise rotation of a subjective effect "warmer" corresponding command and a left turn of a subjective effect "colder" corresponding command is delivered to the system.

For easier, non-manual operation of the comfort or air conditioning can also be Voice control be provided. It is conceivable here for the operator to be able to operate the comfort device by mentioning a specific body region or body part and naming an effect-related command (for example "head slightly colder") or even an effect-related problem description (for example "head is too cold") For example, the voice command "head a little colder" may cause the same changes as when the user manually sets a comfort scale for the head area by one scale range reduced.

With regard to local comfort or climate settings defined for specific body areas, the operator can also be given the option of setting such local settings as a whole personally as optimal and thus as the default value of the automatic function, so that in his future inputs is referenced for all body areas against these defaults. It is conceivable to adjust these settings depending on the season, activity level and / or clothing.

However, the invention also relates to a motor vehicle for carrying out the method according to the invention. Such a motor vehicle has at least one comfort device, in particular an air conditioning device, which has at least components for changing comfort settings, in particular climate settings such as air temperature, air speed, air distribution and air flow direction. Further, the comfort device, in particular air conditioning on at least one input interface, which allows such operation of the user, which is based on the desired subjective effect of the user, such that when changing the comfort setting, especially climate setting via the input interface only an adjustable parameter for Is settable or is made, to which all or at least several, to a desired comfort setting, in particular climate control actually involved parameters are subordinated.

In this way, a highly intuitive and comfortable operation of the air conditioning device can be made available to a vehicle occupant in a motor vehicle. The operation of all involved in a desired effect functions of air conditioning, so for example increasing the temperature, changing the fan speed, adjustment of the air duct flaps and orientation of the vents can thus be done via a central representation and a uniform interaction method and mental model. As a result, in particular, any expandability of the functional scope of the air conditioning device in the motor vehicle is made possible without requiring changes to the input interface. Because not the function, but the effect determines the mental model of the operator and thus also the input or user interface.

It should be expressly pointed out that the method according to the invention can generally be used very advantageously for changing comfort settings in a motor vehicle. So it is conceivable that the method can be used instead of or in addition to changing climate settings for changing audio settings.

In particular, in the control of sound settings in a multi-channel audio system, the placement of "sound spots" in the interior including the adjustment of the volume and directional characteristic analogous to the perceived temperature and spot / diffuse setting in the air conditioning is conceivable.

In particular, the air conditioning device of the motor vehicle may also include body-near effective components, in particular infrared radiators, heatable surfaces and also body-near effective fans. Close-up effective components are usually located in the immediate area of an operator.

It should be noted that conventional air conditioning systems (eg, cooling circuits, PTC air conditioning, heat pumps, etc.) require a large amount of energy to provide adequate heat and cooling capacity. This can lead to a significant limitation of the range, especially in the case of electrified vehicles (electric or hybrid vehicles).

Close-to-the-body systems with comparatively low energy requirements provide a solution here because they can be installed decentrally in the immediate vicinity of the operator in the motor vehicle and thus their effect can be more selectively fed to the operator.

In particular, such a system can consist of many, individually controlled and to be operated "air conditioning units". Against this background, the advantage of the method according to the invention for facilitating the operation by the operator is all the more comprehensible. The combination of a separate adjustment of the individual units would overwhelm most customers or it might not be energy efficient Combinations of activated climate components come.

Preferred embodiments of the invention are illustrated in the drawings and will be explained in more detail in the following description. Here, the same reference numerals refer to the same, comparable or functionally identical components, with corresponding or comparable properties and advantages are achieved, even if a repeated description is omitted.

First, on the 1 Referenced.

This is an air conditioning unit 1 shown extremely schematically for carrying out the method according to the invention. The air conditioning 1 has a central climate control 21 on. The climate control 21 stands with various air conditioning components 13 to 18 in signaling connection, so that the climate control 21 the air conditioning components 13 to 18 control and / or if necessary, a mutual signal flow is possible.

Representing one or more, distributed in the motor vehicle, air conditioning components only one symbol is shown in each case.

This is how the numeral designates 13 Fan for changing the amount of air or the air flow, the numeral 14 Air dampers for releasing or distributing an air flow in air ducts, the numeral 15 Outlet to align an airflow.

With numeral 16 is a central air conditioning indicated, which may be formed for example as a conventional refrigeration cycle or as Peltier air conditioning. The numeral 17 indicates heating resistors, with the example, seats or backrests, windows, a steering wheel or other surfaces, such. B. a footrest, can be heated.

The numeral 18 stands for any arranged in the vehicle interior infrared radiator.

The air conditioning components 13 to 18 are each actually assigned to a desired comfort setting involved parameters P1 to P6.

Here, P1 is an air quantity to be set, P2 air damper opening angle to be set, P3 air outlet directional angle to be set, P4 an air temperature to be set, P5 an electric current to be set, and P6 a radiation intensity to be set.

To bring about a desired climate setting in the motor vehicle is an operator via an input interface 11 given the opportunity to change a parameter P.

The parameter P is purely impact-oriented from the point of view of the user. That is, when changing the parameter P is done by the central climate control 21 a needs-based, function-oriented control of the air conditioning components 13 to 18 so that the parameters P1 to P6 or at least a part of these parameters are changed in order to bring about the climate desired by the user. The parameters P1 to P6 are therefore the input parameter P, which, if desired, changes the climate to the user via the input interface 11 subordinated for the purpose of recruitment alone.

The input interface 11 is designed as a touch-sensitive input surface, in particular as a so-called touch screen.

Alternatively or additionally, an input interface in the form of a rotary or Drehdrückstellers 23 be offered (see also 2 ).

In the figure is further a on-board sensor 22 indicated in the motor vehicle, which carries out climate measurements at different points in the interior of the motor vehicle and / or in the body-near areas of an operator, for example a measurement of temperature and / or humidity.

Furthermore, it is suggested that the central climate control 21 on a storage unit 12 accesses, in the default presets of an automatic function of the air conditioning 1 are stored. The saved default settings correspond to certain settings of the parameters P1 to P6, for which an "average operator" feels comfortable, and are based on empirical investigations for specific external conditions.

Alternatively or additionally, the central climate control 21 their information, however, also from the on-board sensor 22 relate, which detects the individual condition of the operator with appropriate execution.

For body-related comfort or climate adjustment is the operator on the input interface 11 a virtual representation of a person or even a video image of himself represented. The virtual representation can by means of an image processing unit 19 can be generated and for generating a video image in the motor vehicle one or more camera systems 20 (for example on a CCD or CMOS basis).

The in the storage unit 12 Defined standard settings for the automatic function are manually adjustable in order to reduce the need for adaptation in the case of excessively large, individual deviations. But it can also be provided that the air conditioning 1 in that it is designed as a learning system, as that frequently performed adjustments of an operator, after a certain algorithm to be defined on the stored defaults in the memory unit 12 impact, that is to adapt them automatically.

In 2 is now a top view of the input interface 11 shown. The input interface designed as a touchscreen 11 has a touch-sensitive input surface 110 on, on the centrally the virtual image of an operator M is shown. The operator M is subdivided into several body parts that can be selected individually or cumulatively by the operator. Thus, the operator M has selectable legs M1, a selectable body M2, a selectable head M3, and selectable arms M4.

In the illustration, to obtain a desired climate setting, the operator has selected both the legs M1 and the head M3 of the virtual operator M (see hatched areas). The selection is made by tapping these areas, whereby by a single tap of a body part whose selection and by repeated tapping the cancellation of such a selection is possible.

At the same time is on the input surface 110 a bar-like adjustment range 111 in which the "sensed temperature" in the selected body parts M1 and M3 can be changed by means of a horizontally displaceable slide control SR by the operator.

The adjustment range 111 For this purpose, it is subdivided into seven climate stages KS which, starting from an average climate level KS0 or middle position of the slide control SR, lead to a setting direction "colder" (FIG. 112 , dyed blue and / or with "-") or "warmer" ( 113 , dyed red and / or provided with "+") can be selected.

Thus, the operator does not make an absolute setting or preselection of a parameter (such as setting or preselecting a specific temperature in degrees Celsius), but only a qualitative or relative parameter setting, which is referenced to the standard setting of the automatic function (average climate level KS0) ,

When changing the desired climate by the operator to a colder, perceived temperature can be suitably provided that the selected body parts in their color turn to a blue, which changes with increasingly colder climate stage in its hue and / or in its brightness , Analogously, it is conceivable that the body parts M1 and M3 assume a red color, which changes with increasing colder climatic stage in their hue and / or in their brightness. In this way a good traceability of the climate attitude can be supported.

It is important, however, that when the user wishes to change, he only needs to adjust one parameter, in particular qualitatively to a more or less variable parameter, namely the temperature he feels. This can be done with the parameter P (cf. 1 ).

The operator does not have to worry about the climate control 21 the downstream air conditioning components 13 to 18 to set required parameters P1 to P6. The technical-functional relationship between the desired, "perceived temperature" and the required adjustment of existing air-conditioning components can be of no concern to the operator. Thus, despite the existence of a possibly highly complex system, a very simple and intuitive operation is possible.

Furthermore, the operator has the option of defining a selection of permissible thermal transmission paths via the touchscreen.

Touching a part of the body to set the climate it feels will give the operator four standard thermal transmission paths as standard 115 to 118 offered, where 115 Infrared radiation (ie heat radiation), 116 and 117 Air temperature and draft (ie convection) and 118 Contact heat (ie heat conduction) mean.

The operator now only has the option of at least one of these thermal transmission paths 115 to 118 to exclude the desired climate (a more extensive attitude is not possible at this point and also not wanted).

This he can do, for example, energy reasons, because he considers a thermal transmission path for particularly energy-consuming. The exclusion of a specific thermal transmission path (in the diagram, it is drafts 117 ) can also be done because a user simply can not stand such a thermal transmission path. Due to a more frequent exclusion, such an exclusion can also be proposed by default in a learning system.

It should be mentioned that each climate stage KS a certain control of the intensity of all available thermal transmission paths or air conditioning components 13 to 18 so that their combination always results in optimal, perceived comfort for the operator.

The deactivation of individual thermal transmission paths by the operator is similar to climate control 21 the incurred "comfort loss" by increased use of other thermal transmission paths but again.

As already mentioned, the user can input alternatively or additionally via the rotary control 23 perform, which is also a display 230 Having, with an indicated virtual operator and by rotation and pressure of a medium climate level KS0 outgoing, and selectable climatic KS has. The on the rotary knob 23 The apparent climate scale is analogous to the setting range 111 seven-level training.

3 shows a slightly different way, like an operator using the touchscreen 11 Climate adjustment can make.

In contrast to the execution according to 2 Here, the virtual operator M is formed three-dimensionally, so that the operator a left and / or right leg M11 / M12 and a left and / or right arm M41 / M42 can be selected.

In the illustration, the operator has selected the head M3. In addition to the adjustment range 111 , which can be understood as a kind of "master controller", becomes a further setting range on the selected body part (here head M3) 111 Plotted graphically, which is to be operated in an analogous manner as already described. The desired climate setting for the head M3 in this case, both over the adjustment range 111 as well as over the adjustment range 111 ' respectively.

If the operator desires the simultaneous adjustment for several body parts, for example for the head M3 and the left arm M41, then he touches them one after the other so that they are activated for adjustment and highlighted graphically (not shown). In this case, the climate setting for both body parts is only via the "Master controller" 111 performed. By a repeated touch of a body part this can be deactivated again.

An appropriate selection or deactivation of thermal transmission paths 115 to 118 is given in the same way.

For example, if the operator uses the thermal transmission path 117 (Draft) deactivated as shown, so is in particular a change of the slider SR in the direction of "cooler" prevents that of the climate control 21 to change the temperature felt by the user towards a cooler and the relevant in the motor vehicle, relevant fan 13 be controlled so that there is an increase in the amount of air or air speed due to an increase in the fan speed.

In 4 Yet another flexibilization of the climate operation by the operator is shown.

In contrast to the exemplary embodiments shown here, the operator has the option of selecting any body regions as sites of action for a desired, perceived climate change.

A selection of a body region is carried out by touching the virtual operator M (or a video image of the operator) at any point. As a result, a preferably circular "Klimaspot" is generated. Of course, the shape of a climate tag generated can also be chosen differently. In the illustration, the operator has generated a climate spot S1 on the forehead of the virtual operator M and a second climate spot S2 in the foot area of the operator M. A deactivation of a once generated climate SPots can analogous to the comments on 2 by simply tapping the climate spots done in a simple manner. To change the sensed temperature in the selected areas, in turn, the slider SR within the setting range 111 be used in the manner already described. Equally standing the thermal transmission paths 115 to 118 ready for selection or deactivation.

Deviating from the embodiment, however, even more or less than two climate spots can be generated.

If only one climatic poll is generated, the user still has very interesting interaction options available for manipulating the climate poll in the selected area.

So shows 5 in that a selected climatic control S can result in an increase or reduction of the perceived temperature in the selected body region by a rotation of the climate control S by an operator B in the counterclockwise direction or in the counterclockwise direction.

Alternatively, however, a corresponding change via the slider SR in the adjustment range 111 possible.

6 shows that an operator B can increase a generated climate control S by a "zoom gesture" and so can set a continuous adjustment of a spot / diffuse effect. In the illustration, the climate clot S generated is pulled apart to a larger climate spot S ', so that the diffuse effect on the operator in this area is increased, which means a corresponding control of the existing outlets 15 (see 1 ).

A reverse direction of movement, i. H. a reduction of a climate spot generated (for example, from S 'to S), of course, is also possible.

Again, a corresponding change in the climate setting (colder, warmer) for climate control S via the slider SR in the adjustment range 111 possible.

Finally, any shift of a climate spot S once generated, as shown in 7 is shown. In this case, the operator B moves a generated climate variable S obliquely downwards to another body region and thus generates a climate control S 'whose climate settings are in turn set via the slider SR in the adjustment range 111 are possible and / or which in turn can be manipulated in the manner illustrated in the preceding figures.

In the 5 to 7 Incidentally, this is a necessary, virtual representation of the operator B on the input surface 110 for the sake of simplicity, not shown.

The method according to the invention can be used particularly well in the case of equipment of a vehicle which is also equipped with decentralized air-conditioning components which are effective close to the body and thus typical performance-related air conditioning wishes (eg "head cooler") without the invention only by means of more complex setting procedures on several functions can be realized.

However, the use of the method according to the invention is certainly conceivable even with simpler equipment, where existing air ducts are used with louvers and end vents with connection to a central air conditioning. Optionally, electrical-actuated directional adjustments and an individual controllability of air temperature and / or air speed already exist.

In simple automotive air conditioning equipment, the air conditioner usually does not have the ability to actively change the temperature for individual temperature zones in the vertical direction. It can be generated or mixed in the air conditioner only one temperature and passed through the existing duct and flap system in the interior. Here, the idea of the invention can already be used advantageously in that the climate effect desired at a place of action is only generated via the air distribution, the air quantity and, if necessary, also via the air temperature.

Specifies an operator via a suitable user interface (eg via a touchscreen), that its climatic sensation on a part of the body (eg on the head) should become "warmer" or "colder", then the following change of the "subordinate" parameters air distribution, air quantity and air temperature is conceivable:
Wherever it is supposed to be "warmer", more warm air is led in winter and correspondingly less in summer. A "more" is accomplished by aligning the air distribution to the appropriate place of action and by increasing the total amount of air produced. The alignment of the air distribution can be done by appropriately controlling the existing louvers so that a larger proportion of the air generated by a fan of the air conditioner total air is directed as previously to the site of action. The increase in the total amount of air generated can be realized by appropriate activation of the fan (increase the fan speed).

There, where it is supposed to be "colder", less warm air is conducted in winter and accordingly more in summer. A "less" is accomplished by aligning the air distribution away from the corresponding point of action and by reducing the total amount of air produced. The alignment of the air distribution can be carried out by appropriately controlling the existing louvers so that a lesser proportion of the total air generated by a fan of the air conditioner is directed as previously to the site of action. The reduction of the total amount of air generated can be realized by appropriate activation of the fan (reduction of the fan speed).

If necessary, the air temperature can be raised or lowered to compensate globally for other sites of action. A corresponding fine adjustment, as the subordinate parameters are to be controlled in detail, can be set via stored characteristics in the air conditioning control unit.

However, for future vehicles, especially electric or hybrid vehicles with a high demand for energy efficiency, more complex air conditioning systems with different units for heating or cooling the operator in different environmental conditions are conceivable.

That's how it shows 8th an example of a more complex system with additional close-fitting heating and cooling components.

In the figure, a motor vehicle K can be seen, with an air conditioning 1 , which have a central air conditioning 10 features. The central air conditioning 10 is equipped with a non-illustrated fan and air ducts 100 connected with not shown louvers and end vents. The central air conditioning 10 is preferably designed as Peltier air conditioning, but can also be equipped as a conventional air conditioning with a cooling circuit.

As effective, air-conditioning components are in the seating area a backrest heater 3 and a seat heater 4 it can be seen, which for close-to-body cooling with fans 31 respectively. 41 be supplemented.

In addition, in the neck area is an infrared emitter 2 seen.

For spot air conditioning in the area of the headliner is a fan 5 arranged, which is operable in both a spot and in a diffuse characteristic.

Likewise in the area of the headliner is again an infrared emitter 6 intended.

A steering wheel heater 7 provides contact heat for the well-being of an operator B.

Finally, even in the footer of the operator B is an infrared emitter 8th arranged, which is to heat the feet of the operator B from above close to the body.

To heat the feet from below by contact heat is a heated surface 9 , Finally, the motor vehicle K also has heated side windows.

There are thus all thermal transmission paths (heat convection, heat conduction and heat radiation) available to provide the operator B a desired indoor climate.

In the manner already described, the operator B can via input interfaces 11 and or 23 a desired climate in the form of a superordinate parameter P (cf. 1 ), so that the air conditioning components of the air conditioning 1 be automatically controlled accordingly.

In the 9 By way of example, another possibility of an effect-oriented climate adjustment via an input interface in the form of a touchscreen is shown. The person to be air conditioned is only schematically seen on a touch screen, not shown. It is divided into legs M1, fuselage M2 and head M3.

For setting a local climate offset, the operator B first touches the desired body part, for example the head M3. Then, on both sides of the head M3 virtual offset Control knobs O1 and O2 (for example as plus and minus sign) are displayed ( 9a ).

If, for example, the operator B touches the offset adjustment knob O2, then a warmer climate is locally generated at the head M3, which is indicated by an offset symbol OS1, for example in the form of a plus sign ( 9b ).

Analogously, it is conceivable that the operator B sets a negative climate offset on the legs M1, by touching the legs M1 and then touching the then displayed offset adjustment knob O1.

The adjusted local climate offsets can be visualized by the offset symbols OS1 and OS2 (cf. 9c ). A local climate offset can preferably be set only for the head M3 and / or for the legs M1 and also only in one stage.

Additionally or alternatively, it is conceivable to make the set, local climatic offsets or different local temperature levels graphically recognizable by color change or by different filling patterns of the body parts M1, M2, M3.

In particular, the use of a seven-level color gamut has proven to be expedient for rapid detection:
Third cold level = dark blue
Second cold level = blue
First cold level = light blue
Default = gray
First warm step = light red
Second warm level = red
Third warm level = dark red

In a color representation of climate levels, in the initial setting (default setting) according to 9a So all body parts M1 to M3 are grayed out. As representation for the local, positive climate offset at the head M3 according to 9b , the head M3 is bright red. A local, negative offset for the legs M1 can be indicated light blue.

In addition or as an alternative to the setting of local climate offsets, an operator has the option of carrying out a global climate offset via an operating switch D (for example designed as a rotary switch). This therefore has an effect on all body parts M1 to M3. Upon rotation of the control switch D in the counterclockwise direction, a global cooling takes place, with rotation of the control switch D in a clockwise direction global warming.

In 9d it is shown that the operator has selected a negative global offset (minus sign). In 9e a positive, global offset was set. However, the offset symbols OS1 and OS2 remain faded in to remind the operator of the already locally carried out climate offsets. These are still active.

It should be noted that the negative, global climate offset ( 9d ) every body part has dropped one climate step "lower". The fuselage M2 has moved from the default setting to the one previously set ( 9c ) was assigned to the legs M3 and therefore can now be displayed in light blue. The legs M3 have fallen correspondingly in the climate feeling one step lower. These can now be assigned the color blue. Accordingly, the head M3 is shown in gray.

Similarly, the climate levels after the adjustment of the positive, global climate offsets ( 9e ). In this case increases, starting from 9c Each body part thus a climatic level "higher". The head M3 can be red, the hull M2 light red and the legs M1 can be gray again.

In the 9 However, only one representation by means of different filling pattern is visible.

While the local climate offsets are realized by corresponding changes in the subordinate parameters, such as air quantity and air distribution (as already described), the global climate offset is accomplished by a corresponding change in the air temperature.

The invention is not limited to the above embodiments. These were used only for general explanation of the essence of the invention. Rather, within the scope of its scope, the invention may assume other than the embodiments or forms described above. In this case, it may in particular also have features which represent a combination of individual features of the respective claims.
