Description

The invention relates to a method for setting dynamic driving properties of a vehicle, in particular a passenger car.

Vehicles such as, for example, motor vehicles, in particular passenger vehicles, whose driving dynamic properties can be set, that is to say can be varied as required by a person such as the driver of the vehicle, are already well known from the general prior art. For example, an operating element is arranged in the interior of the vehicle, which can be a button or a button. By actuating the control element, at least one driving dynamic property of the vehicle can be changed. If the driver actuates the control element, the chassis of the vehicle becomes stiffer or tighter, for example. The rigidity of the undercarriage can be reduced again by actuating the control element again.

The change or setting of the at least one driving dynamic property can thus be understood to mean that a property, in particular a stiffness, of a chassis and / or a property of a drive train of the vehicle is set, that is to say varied. By increasing the rigidity of the chassis, for example, rolling movements of the vehicle or its body, in particular its body, can be reduced.

Alternatively or additionally, it is possible to set the at least one property via a display of the vehicle. By means of an operating element, such as a rotary push-slide actuator, for example, the driver can navigate through different menus of a graphical user interface and thereby adjust the vehicle's driving dynamics properties as required.

The DE 10 2012 010 490 A1 discloses a method for setting vehicle functions in a vehicle, the vehicle functions being displayed, for example, on a touch-sensitive screen. Pictograms are displayed on the touch-sensitive screen, each of which is assigned at least one setting. The setting belonging to the pictogram touched is made by touching the respective pictogram.

Furthermore, the US 2014/0188350 A1 a control system for a vehicle, by means of which a variety of driving modes can be set.

In addition, the US 2010/0049408 A1 to take a control device for a vehicle as known, wherein different functions of the vehicle can be set by means of the control device.

Furthermore, the DE 10 2006 049 727 A1 an operating concept for setting various driving dynamics characteristics on a non-lane-bound motor vehicle, in particular passenger cars, can be seen as known. A different behavior of actuators influencing the longitudinal dynamics, the vertical dynamics and the lateral dynamics of the vehicle can be selected for different driving conditions. Furthermore, it is provided that one or more defined types of use for the motor vehicle can be selected by means of a first operating element, which alone influence one or more longitudinal dynamics actuators and that at least three different driving dynamics characteristics in the range between comfort and maximum can be used by means of a second operating element Stability on the one hand and sportiness and limited stability on the other hand can be selected. In the areas, there is a positive coupling between longitudinal dynamics actuators, vertical dynamics actuators and transverse dynamics actuators, while in at least one further individually adjustable driving dynamics characteristic, the aforementioned forced coupling is eliminated.

The object of the present invention is to create a method by means of which at least one driving dynamic property of a vehicle can be set in a particularly simple, comfortable and comprehensible manner.

This object is achieved by a method having the features of patent claim 1. Advantageous refinements with expedient developments of the invention are specified in the remaining claims.

The method according to the invention for setting at least one driving dynamic property of a vehicle, in particular a motor vehicle such as a passenger car, comprises a first step in which at least one image stored in an image file is displayed on a display of the vehicle. In a second step of the method, an input is received by a person via at least one control element of the vehicle, by means of which the person selects at least a partial area of the image. The person is, for example, an occupant, in particular the driver, of the vehicle. The control element is, for example, a switch, a button, a rotary push-button actuator, a rotary push-push actuator or else the display itself, which for example as Touch-sensitive screen, that is, a so-called touchscreen. Here, the person can make the entry and thus select the image or at least the partial area of the image in such a way that the person touches the display or the touch-sensitive screen.

In a third step of the method, data stored in the image file are analyzed. As will be explained in more detail below, the data can include image data, on the basis of which the image is shown on the display in such a way that the image is optically perceptible to the human eye. As an alternative or in addition, the data can include other data, so-called information data, which are not used to display the image on the display, but which belong to the image and, for example, describe attributes or parameters associated with the image, which are explained in more detail below.

In a fourth step of the method, the driving dynamic property is set as a function of the analyzed data. The background of the invention is to use the image as a so-called mood image, on the basis of which the driving dynamic property is set, that is to say varied. The person associates with such a mood picture emotions, in particular a mood, situations and / or surroundings, which are used by the method according to the invention for adjusting the driving dynamic property of the vehicle. It is thus possible to set the driving dynamic property in such a way that the driving behavior of the vehicle matches, for example, the emotions caused by the mood picture. As a result, the driving dynamics property can be set in a particularly simple, comfortable and comprehensible manner.

In this case, the image data describing at least the partial area and stored in the image file are analyzed. As already indicated above, the image data are used in particular to display the image on the display in such a way that the image can be visually perceived by the person with their eyes. The image data thus contain, for example, color information. It is thus possible to set the driving dynamic property as a function of colors of the image characterized by the image data. If, for example, it is determined in the course of the analysis that the image predominantly has warm colors such as yellow, red or orange, it can be concluded that the image visualizes a calm, warm and relaxing place. As a result, the dynamic driving properties of the vehicle can be set in such a way that a comfortable and relaxing journey is possible. If, however, the analysis determines, for example, that the image comprises at least predominantly cold colors such as blue and white, it can be concluded that the image conveys a cold and tense and / or sporty situation. As a result, the driving dynamic property can be set, for example, in such a way that a particularly sporty ride is made possible. In order to realize the comfortable ride, for example, a low rigidity of a chassis of the vehicle is set, for example a higher rigidity of the chassis is set to implement the sporty ride, so that the chassis is tight and sporty.

In a further advantageous embodiment of the invention, when analyzing the data, at least the partial area is subjected to image processing, with colors and / or objects and / or human body parts being recognized at least in the partial area by means of the image processing. In other words, it is provided that color and / or object recognition is carried out, so that the driving dynamic property is set as a function of recognized colors and / or objects or body parts. If, for example, it is recognized that there is an object in the form of a road with a large number of curves in the image, it is concluded, for example, that a sporty driving style is desired. As a result, a high rigidity of the chassis is set, for example. However, if, for example, objects such as candles or human body parts, in particular heads and / or faces, are recognized, the desire for a comfortable driving style can be deduced, so that the driving dynamic property is adjusted accordingly.

Another embodiment is characterized in that information data belonging to the image is analyzed. This information data is not used to visually display the image on the display, but rather the information data describes parameters belonging to the image. For example, the information data characterize a time at which the picture was taken. Alternatively or additionally, the information data characterize a temperature prevailing at the time the picture was taken and / or a pressure prevailing at the time the picture was taken and / or a height from which the picture was taken. Alternatively or additionally, the information data characterize a person who took the picture and / or a device by means of which the picture was taken. Alternatively or additionally, the information data characterize a location at which the picture was taken. The background of this embodiment is not the optically perceptible image itself, but parameters belonging to the image, that is to say the Use information data to set the driving dynamic property, since, for example, the person associates states characterized by the information data with the selected image. If, for example, the picture was taken at a location with a high temperature, which is characterized by information data, but not necessarily by the picture itself or the picture data, then the desire for a relaxing and comfortable journey can be concluded.

A further embodiment is characterized in that a plurality of images stored in respective image files are shown on the display, of which the person selects at least one image. The images are displayed, for example, simultaneously or one after the other. As a result, the person can select at least one of the images from a large number of images and set the driving dynamic property as a function of the selected image. The images functioning as mood images are stored or stored, for example, in an image library such as a data cloud, on a memory card or on a USB stick.

Furthermore, it is additionally conceivable, depending on the selected image, to set an illumination device for illuminating the interior of the vehicle and / or a reproduction device for reproducing sounds and / or images in the interior. Furthermore, it is alternatively or additionally conceivable to set an air-conditioning device for air-conditioning the interior and / or an information depth or an information content on a display as a function of the selected image, depending on the selected image. As a result, the vehicle as a whole can be adjusted in a simple, comfortable and comprehensible manner on the basis of mood images and, for example, adapted to a person's current mood.

A further embodiment of the method comprises a fifth step, in which a first image stored in a first image file and at least one second image stored in a second image file are simultaneously displayed. In a sixth step of the method, an input effected by the person via the control element is received, by means of which the person selects the first image and the second image by the person selecting a location on the display. The location is arranged between the images, for example, but can also be arranged on one of the images. In a seventh step of the method, first data stored in the first image file are analyzed. In an eighth step of the method, second data stored in the second image file are determined. In other words, the first four steps of the method described above are carried out, but for each of the images displayed. Finally, in a ninth step of the method, the driving dynamic property is set depending on the analyzed first and second data. This makes it possible, for example, to use more than just one mood picture in order to set the driving dynamic property. This makes it possible, for example, to compromise between an excessively sporty and an excessively comfortable setting.

In order to implement a particularly simple and needs-based setting, it is provided in a further embodiment of the invention that in a tenth step of the method, a first distance between the location selected by the person and the first image is determined. In an eleventh step of the method, a second distance between the location selected by the person and the second image is determined. In a twelfth step of the method, the first and second data are weighted as a function of the determined distances. In a thirteenth step, the driving dynamic property is set depending on the weighting of the first and second data.

If, for example, it is determined on the basis of the analysis of the first and second data that the first image suggests a desire for a comfortable driving style, but the second image indicates a desire for a sporty driving style, and if the distances are the same, a compromise between sporty and comfortable setting, for example, the chassis. However, if the second distance is, for example, smaller than the first distance, the driving dynamic property is set in such a way that a more sporty than comfortable ride is realized. By selecting the position, the person can thus express their preference and carry out an at least essentially stepless weighting of the images, so that, for example, a sporty setting of the vehicle can be implemented, but excessive sportiness, that is to say, for example, an excessive hardness or rigidity of the chassis, is avoided can.

Finally, it has proven to be advantageous if at least one property, in particular a stiffness, of a chassis and / or at least one property of a drive train, in particular an engine and / or a transmission, of the vehicle is set as the driving dynamic property. For example, within the scope of the setting of the property of the drive train, it is possible to have an accelerator pedal characteristic, that is to say the throttle response of the one designed for example as an internal combustion engine or an electric motor Motors to adjust. The setting of the driving dynamic property is also to be understood to mean that, for example, the vehicle is steered, particularly with regard to its directness or translation.

The method according to the invention makes it possible to be able to adjust and change the driving dynamic property quickly according to the perception of the person. The person quickly gets an impression of the type of attitude that awaits them through the mood picture. An unemotional and abstract scrolling through lists or menu levels can thus be avoided.

Using the control element, which is designed, for example, as a touch-sensitive screen, it is also possible to select the desired image or images quickly and comprehensibly and thereby, for example, to carry out an overall change in the vehicle. Linguistic and cultural barriers do not exist here, since the setting of the property takes place via mood pictures.

Within the scope of the method it can be provided that, for example, a first parameter characterizing a state in the interior of the vehicle is detected by means of at least one first sensor. Alternatively or additionally, it is conceivable to use at least one second sensor to detect at least one second parameter characterizing a state in the surroundings of the vehicle. It is preferably provided to include the detected first parameter and / or the detected second parameter in the setting of the driving dynamic property, so that an at least substantially optimal state of the vehicle is determined, for example, by means of a computing device, in particular a control unit, and by the setting the driving dynamics property can be brought about.

The invention also includes a vehicle, in particular a motor vehicle and preferably a passenger car, which is designed to carry out a method according to the invention.

Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing.

• 1 eine schematische Vorderansicht einer Anzeige eines Fahrzeugs, auf welcher wenigstens ein Bild angezeigt wird, anhand dessen im Rahmen einer ersten Ausführungsform eines Verfahrens wenigstens eine fahrdynamische Eigenschaft des Fahrzeugs eingestellt wird; und
• 2 eine weitere schematische Vorderansicht der Anzeige, mittels welcher eine Mehrzahl von Bildern angezeigt wird, anhand derer im Rahmen einer zweiten Ausführungsform des Verfahrens die wenigstens eine fahrdynamische Eigenschaft des Fahrzeugs eingestellt wird.

The drawing shows in:

• 1 a schematic front view of a display of a vehicle, on which at least one image is displayed, on the basis of which at least one driving dynamic property of the vehicle is set in the context of a first embodiment of a method; and
• 2 a further schematic front view of the display, by means of which a plurality of images are displayed, on the basis of which the at least one driving dynamic property of the vehicle is set in the context of a second embodiment of the method.

Identical or functionally identical elements are provided with the same reference symbols in the figures.

1 shows a schematic front view of a whole with 10 Designated display of a vehicle, which is designed for example as a motor vehicle and preferably as a passenger car. The ad 10 is a device for displaying images and at the same time a control element of the vehicle since the display 10 is designed as a touchscreen, that is to say as a touch-sensitive screen. This makes it possible for a person in the interior of the vehicle, such as the driver of the motor vehicle, to touch the display 10 Functions of the vehicle and in particular inputs. Based on 1 and 2 describes a method for setting at least one driving dynamic property of the vehicle, with the aid of 1 a first embodiment and based on 2 a second embodiment of the method is explained.

The first step of the process will be on the display 10 a plurality of images 12a-f displayed with the pictures 12a-f simultaneously on the display 10 are displayed. The pictures 12a-f are stored in respective image files, the image files being stored, for example, in a storage device of the vehicle or in a storage device external to the vehicle, for example in a data cloud. Out 1 is recognizable that the pictures 12a-f in respective sections of the ad 10 are arranged. In a second step of the method, the person, in particular the driver, uses the display 10 input by means of the display 10 received, the person by entering one of the images 12a-f selects. For example, to select the image 12b touches the person with one of his fingers the part or part of the part in which the image 12b is arranged.

In a third step of the method, data which is in the image file in which the image 12b is saved, analyzed. In a fourth step of the method, the at least one driving dynamic property is finally set as a function of the analyzed data. in the As part of the analysis of the data, the picture 12b for example subjected to image recognition, in particular object recognition. The picture 12b is visually perceptible to the person through their eyes. How from 1 can be seen are in the picture 12b a plurality of successive curves of an at least substantially meandering street can be seen. These curves are objects that can be recognized during the analysis of the data. This recognition of the curves in connection with the fact that the person has the picture 12b selected, suggests that the person desires a sporty driving style. Accordingly, the driving dynamic property is set such that a sporty driving style can be implemented.

As part of the setting of the driving dynamic property, for example, a rigidity of a chassis of the vehicle is increased. Furthermore, for example, steering of the vehicle is set more directly and an accelerator pedal characteristic is changed such that a particularly high torque can be requested from an engine, in particular from an internal combustion engine of the vehicle, from the driver with only a slight movement of an accelerator pedal.

This based on picture 12b The illustrated method can also be used in relation to the other images 12a and 12c-f be performed. The picture 12a shows, for example, a racetrack or part of a racetrack, which is recognized by the analysis. As a result, the desire for a sporty driving style is concluded. The picture 12c shows a variety of roads, which can also be used, for example, to suggest a sporty driving style. The picture 12d shows a person in the foreground and sky and meadow and a leaf in the background, so that the picture 12d suggests a relaxed and comfortable driving style. For example, the person would take the picture 12d select, for example, a significantly lower rigidity of the chassis would be set to enable a particularly comfortable and relaxing ride.

The picture 12e shows a winter landscape. The person chooses the picture 12e winter road conditions can be inferred, so that the dynamic driving properties are set in such a way that particularly safe operation in snow can be achieved. 12f finally shows an uneven terrain on which an all-terrain vehicle is moving. By selecting the picture 12f can be concluded that the person wishes to move the vehicle on an uneven surface. It is then possible, for example, to set the driving dynamic property in such a way that a ground clearance of the vehicle is increased.

The following is based on 2 illustrates the second embodiment of the method. Also in the second embodiment, a plurality of images 14a-e on the display 10 shown with the pictures 14a-e on the display 10 displayed at the same time. For example, the person would take the picture 14b or the picture 14c can be used to infer the desire for a sporty driving style. Selecting the picture 14a suggests winter road conditions. Selecting the picture 14d indicates the desire for a relaxed driving style and the selection of the picture 14e suggests, for example, the desire for an efficient driving style. In order to implement the efficient driving style, for example, the aforementioned gas acceptance is reduced compared to the sporty driving style, so that the fuel consumption of the internal combustion engine can be kept low.

In the first embodiment, only one of the images can be used 12a-f be selected so that a stepped setting or a direct operation of the driving dynamic property is shown. In contrast, in the second embodiment, an at least substantially continuous adjustment of the driving dynamic property is possible. In the second embodiment, the person via the control element or the display 10 received input, by means of which the person present at least the image 14a as the first picture and the picture 14d as a second picture by selecting the person with his index finger 16 an agency 18 the ad 10 selects.

Out 2 is recognizable that the body 18 both from the picture 14a as well as from the picture 14d is spaced. In the second embodiment, first data is analyzed that is in the image file of the image 14a are saved. Furthermore, second data are analyzed, which are in the image file of the second image 14d are saved. Furthermore, a first distance of the point 18 to the first picture 14a determined. It also adds a second distance to the spot 18 from the second picture 14d determined. The analyzed data are finally weighted depending on the determined distances. Then the driving dynamic property is set depending on the weighting of the first and second data. The second embodiment is based on the pictures 14a and 14d described. It is easily conceivable, also the other pictures 14b . 14c and 14e and to include their image files in the setting of the driving dynamic property, but this is not explained in more detail because of the overview.

Out 2 it can be seen that the second distance between the point 18 and the second picture 14d much less than the first distance between the point 18 and the picture 14a is. Thus, the second data is weighted more heavily than the first data, so that a compromise between the setting of the driving dynamic property according to the picture 14a and after the picture 14d with tendency to adjust the driving dynamic property according to the picture 14d is created. Would the job 18 for example in overlap with the picture 14d would lie, the driving dynamic property only according to the picture 14d be set, and the rest of the images 14a . 14b . 14c and 14e would not be taken into account when setting the driving dynamics property. This adjustability makes it possible, for example, to adjust the vehicle or its driving dynamics comfortably, but to avoid an excessively comfortable setting while avoiding an excessive adaptation to winter road conditions, but an adaptation to winter road conditions, which is caused by the image 14a be characterized, taken into account. This creates an advantageous compromise between the implementation of comfortable driving behavior and safe locomotion in wintry road conditions.

On the display 10 according to 2 is another job 20 visualized which before selecting the position 18 was selected by the person. Out 2 is recognizable that the body 20 between the pictures 14b and 14c is arranged, whereby a corresponding compromise with regard to the setting according to the picture 14b and the setting according to the picture 14c was created.

Overall is out 1 and 2 recognizable that the described method enables a particularly simple, comfortable and comprehensible setting of the driving dynamic property, regardless of language barriers, since the pictures 14a-e respectively 12a-f can be used as mood pictures with which the person associates emotions. Thus, there are indirect emotions through the pictures 12a-f respectively 14a-e caused by the person, used to adjust the driving dynamic properties of the vehicle.
