The The invention generally relates to detection of user input via an operating system in a motor vehicle, which detect haptic inputs can, via a detection device, which is a touch-sensitive, comprehensively formed position detection unit. As haptic inputs such inputs are considered in which executed a touching operation action is, by means of the touch-sensitive position detection unit is detected. Based on the recorded touch positions determines the user input. To the user a feedback to give to the user via the actuator, which performs the haptic user input while the Acting action transmitted a haptic stimulus. This offers the advantage that operator actions are possible and the user successfully submitted a user input the haptic control feedback can be conveyed, for example indicates that a user input succeeded has been. The successful execution can be detected by the user, without its acoustic and / or optical sense organs for this to use. Is the touch-sensitive Position detection unit, for example with a display device coupled, for example, integral with such a touch screen trained, so is an operation and feedback to the user via an example successfully executed Operation possible without the user, which, for example a driver of the motor vehicle is to turn his eyes away from the traffic got to. Thus, by such an operating system on the one hand a Operational safety when driving the motor vehicle increases and on the other hand an ease of use increased by that feedback is transmitted to the user, as this from the area is used to mechanical controls.

From the EP 1 560 102 A2 For example, there is known a touch-sensitive haptic feedback input device comprising a touch-sensitive position detection unit for detecting touching user inputs and an actuator that moves the position detection unit in at least one direction relative to a reference body, for example a haptic feedback-communicating display device.

From the DE 10 2005 048 230 An input device for a motor vehicle is known which comprises a touch screen and an actuator unit for imparting haptic feedback.

Out the prior art, only simple operating systems are known about the one feedback, d. H. an operator feedback, for complex user input is not adequately possible.

Of the Invention is therefore the object of an operating system and to provide a method for detecting user input, with which a better and more comfortable user input, especially with regard to on a mediation of a haptic control feedback possible is to u. a. to increase operational safety in a vehicle when the user input of a vehicle driver is detected.

The The object is achieved by a device with the features of claim 1 and a method with the features of claim 11 solved. advantageous Embodiments of the invention will become apparent from the dependent claims.

What is provided is a touch-sensitive operating system with a haptic feedback, which comprises: at least one detection device for detecting haptic user inputs made by at least one actuating element, wherein the at least one detection device comprises a touch-sensitive, area-formed position detection unit, a control device for ejecting coupled to the at least one detection device the detected user inputs and at least one coupled to the control device and the detection device actuator device that outputs controlled by the control device via the at least one detection device at least one for the at least one actuating element haptic perceptible stimulus. In this case, it is provided that the at least one haptic stimulus perceptible for the at least one actuation element is varied depending on the detected user input in order to provide the user with feedback. This makes it possible to give the user during the user input an operator feedback, so that an operation without a glance alone by an actuating element, which is preferably a body part, in particular a finger of the user, is facilitated. An inventive method thus provides the steps: detecting a haptic user input by means of a touch-sensitive, area-trained position detection unit of a detection device in which a touch position of at least one operating element of a user is determined, evaluating a position for detecting the user input by means of a control device and driving one with the Detection device coupled Aktorvorrich tion, so that the at least one detection device at least one for the at least one actuating element haptically perceptible stimulus is output. It is provided that the at least one perceptible for the at least one actuator haptic stimulus is varied depending on the detected user input in order to provide the user with a control feedback.

A haptic user input includes an actuation of the detection device, in which the actuator of the user, the detection device touched.

at In a preferred embodiment, the control device and the actuator device is formed while the user input a stimulus parameter that parametrizes the haptic stimulus, continuously to vary over the stimulus parameter a value of continuous status variable of the operating system to the user to convey. A state variable is a variable that has a Condition of the operating system or a state of one by the operating system indicates serviced vehicle system and / or a vehicle function. A continuous state variable is a state variable that Can accept values from a continuous value range. A rotation speed a displayed rotating object on a display surface of the operating system, for example, provides a continuous variable a set temperature, a fan line or similar are also continuous variables.

at Another embodiment of the invention is the control device formed, one or more actuation parameters of a Acting action of the at least one actuating element and optionally a further actuating element for to determine the haptic user input and the at least one perceptible for the at least one actuating element Stimulus adapted to the determined actuation parameters or to vary the several determined actuation parameters to the determined value of the actuation parameter or the values of the determined actuation parameters to the user to convey. Actuation parameters can be, for example a contact duration, a distance between two touch positions or a speed of a wiping touching Be actuation of the detection device. The at least an actuation parameter can be, for example, a movement speed a sliding movement of the at least one actuating element via the surface-trained touch-sensitive Be position detection unit.

Especially Preferably, the at least one stimulus is dependent a user interface logic evaluated by the controller varies, so that in a detected and recognized actuation act, the one not according to the interface logic Represents and / or points to an operator action a warning mediating stimulus is issued or can be output. Is attempted by the user in the example given above, to move the object to a grid position already on another object is arranged, such as a frequency the vibration transmitted to the actuator be changed, for example, be increased. In this case, there is a warning with a high-frequency vibration signal connected. It goes without saying for the expert that other assignments are possible.

at A preferred embodiment will vary of the at least one haptic perceptible stimulus one or two Stimulus parameters that characterize the at least one perceptible stimulus, changed. In particularly preferred embodiments It is provided that the haptic perceptible stimulus two different, separate perceptible and separately controllable stimulus parameters transmitted to the user. A stimulus parameter can be, for example characterize the nature of the stimulus. Another stimulus parameter can For example, characterize the intensity of each stimulus.

at an embodiment, it is provided that the at least an actuator device at least one designed as a vibration unit Actuator element comprises. The at least one haptic perceptible Stimulus is thus on via the detection device the at least one actuator transmitted Vibration. If the stimulus is a vibration, then a first stimulus parameter for example, be the frequency. A second stimulus parameter can be the Intensity, d. H. Amplitude of the vibration, which is too is transmitted to the actuating element. These two Stimulus parameters can vary independently become. In one embodiment, the controller is and the actuator device formed at least two stimulus parameters of the stimulus to vary independently to one another Information content conveyed to the user.

In another embodiment of the invention, the actuator device is designed to control a viscosity of at least one layer of the detection device in order to vary as a haptic stimulus a resilience of the detection device under compressive stress. Particularly preferably, the actuator device is designed to locally control the variation of the viscosity. For this purpose, electrodes can be arranged relative to the viscose layer, via the local electric fields in the viscose layer can be produced, which cause a change in viscosity.

at In yet another embodiment, the actuator device comprises Actuator elements, over which a local height along the local surface normal of the position detection unit is variable. For example, the actuator elements be designed as piezocrystals, the local height the surface of the touch-sensitive position detection unit vary.

It is understood by the skilled person that the different Stimuli triggering actuator elements and embodiments of Actuator device can be almost combined with each other. For example, piezocrystals, which on the one hand a local increase in the surface of the touch-sensitive Position detection unit effect, also used to in addition a vibration to the actuator transferred to.

Of the at least one touch-sensitive position detection unit is preferably a flat, freely programmable Display device associated with a position assignment between Scoring at least one area of the touch-sensitive Position detection unit and positions of a flat display area the display device exists. Leave this form a user interface, at the touch points the touch-sensitive position detection unit Display positions assigned to the display area are. Preferably, the position detection unit is adjacent to the display surface integral with the display device designed as a touch screen.

The Control device is preferably formed on the display device To represent objects that have a pulling movement of the Actuator in contact with the detection device are displaceable and only at predetermined positions or in predetermined Deposited areas, wherein the control device is formed, leaving and / or reaching a predetermined position and / or a predetermined range over an abrupt change of the transmitted perceptible stimulus. Can For example, individual graphically displayed objects at certain Detent positions are arranged on the display surface, so it is customary to define areas of these detent positions which are often referred to as snap areas or snap areas become. If the object moves in this snap area, it will arranged at the corresponding grid position. About here it is easier for the user to move the object to the corresponding one To move grid position. To an object on the display area move from one grid position to another grid position, the user touches the object to be moved in the area, in which it is graphically represented. By a subsequent sliding movement over the touch-sensitive Position detection unit, the object can be moved. To the For example, to convey users that he has seized an object transmit a stimulus to the user. For example a vibration of given frequency and low intensity issued to the user. Once the touch position of the actuator, that from the touch-sensitive position detection unit is determined, the Einrastbereich the original grid position leaves, this is the user mediated by the fact that For example, the intensity of the transmitted vibration is increased abruptly. The user moves the operation object in a rest area of an unoccupied grid position, so is again made an abrupt change in the stimulus, for example an abrupt reduction or a renewed abrupt increase the intensity of the vibration. About this is the User mediates that he can let go of the object by using the Actuator of the touch-sensitive Position detection unit lifts, so that the moving object the new grid position is moved and displayed there.

It results for the skilled person that manifold Other configurations are possible.

Generally it is advantageous if the control device is formed via the haptic control feedback coded additional information of the operating system to the user. For example, in one embodiment provided that while capturing the user input at least one of the stimulus parameters continuous with the duration the detected and recognized actuation action varies if the duration of the continuation of this operation is a recognition of a user input and / or a distinction depends on two user inputs. For example a short touch and a long-lasting touch recorded as different user input, so it is beneficial at a stimulus that transmit in the form of a vibration For example, a frequency will increase continuously while the actuator with the position detection unit is in contact. This conveys to the user that in a continuation of the act of action, the touch of the position detection unit by the Actuator, one of the previously detected user input deviating user input can be effected.

Another communicable status information of the operating system is transmitted in one embodiment to the user, during which the user input via a Rupte change of the at least one perceptible stimulus exceeding a switching threshold in the detected and / or detected user input can be output.

Around a simple and versatile operation through the operating system is the position detection unit preferably designed so that they simultaneously several Berührpositionen capture and determine. This will make it possible to record the acts of operation in which several Actuators or different parts of an actuator simultaneously touch the position detection unit.

at In a particularly preferred embodiment, the Aktorvorrichtung several actuator elements, on the at different Make the surface trained touch-sensitive position detection unit simultaneously different haptic stimuli transferable are. So it is possible to take advantage of touch gestures, the one user by means of several fingers on the touch-sensitive Performs position detection unit, and different To issue stimuli to the two actuators.

at another embodiment provides that the one or more stimuli appropriate for the at least one Actuator are perceptible, depending a number of the detected and recognized simultaneous touches the at least one actuating element and further actuating elements is variable.

The Features of the method according to the invention the same advantages as the corresponding features of the invention Operating system.

following The invention is based on preferred embodiments explained in more detail with reference to a drawing. Hereby show:

1 a schematic representation of an operating system;

2 another embodiment of an operating system;

3 yet another embodiment of an operating system;

4 a schematic view of an operating system for explaining a haptic feedback in response to different detected user inputs;

5 a further schematic representation of an operating system and

6 a schematic view of an operating system on which a navigation map can be manipulated via user input.

In 1 is schematically an operating system 1 presented with a haptic feedback. The operating system 1 includes a detection device 2 for detecting haptic user input via one or more actuators 3 . 4 be made. The actuating elements are preferably fingers of a hand of a user of a motor vehicle.

The detection device 2 comprises a touch-sensitive, areal-trained position detection unit 5 , This is capable of at least one contact position of an actuating element on the position detection unit 5 to investigate.

The position detection unit is provided with a control device 6 coupled, the position information of the position detection unit 5 receives and evaluates, in order to recognize from this user inputs. Each recognized user input can, for example, the absolute contact position of one of the actuators 3 . 4 on the position detection unit 5 , a contact duration, a sequence of touch positions, a speed at which a wiping touch is performed, ie a speed at which a trajectory defined by touch positions is traversed. The control device 6 is with an actuator device 7 coupled by the control device 6 is controllable. The actuator device 7 is with the position detection unit 5 coupled in such a way that the actuator device 7 controlled by the control device 6 , one for the at least one operating element 3 . 4 haptic perceptible stimulus can spend. The haptic stimulus is varied depending on the recognized user input. If, for example, a touch of the position detection unit 5 through the actuator 3 detected at a position associated with a particular function and / or action is, for example, in one embodiment via the actuator device 7 a vibration of the position detection unit 5 which is performed at a first frequency and first amplitude level. This gives feedback to the user that he is the position-sensing unit 5 has touched at a location where a user input has triggered as actuation of the corresponding function and / or action. By contrast, the user touches the position detection unit, for example 5 with the actuating element 3 at a position to which no action and / or function is assigned, so is the part of the controller 6 recorded an incorrect user input, which also represents an actuation or user input as such, and as feedback the user outputs a vibration that has a much higher frequency than the frequency with which the actuator device 7 the position detection unit 5 vibrated when a successful activation of an action / function has been effected by the act of action.

It is understood by those skilled in the art that there are a variety of different ways to design a haptic feedback. In the embodiment just described, the actuator device 7 be formed for example as a vibration unit. An assignment of actions / functions that a user can trigger to positions of the touch-sensitive position detection unit 5 can for example via a display device 8th respectively. Is the touch-sensitive position detection unit 5 For example, configured transparent, so the display device 8th behind the position detection unit 5 be arranged. Such an arrangement, in which the transparent position detection unit is arranged in front of a display surface, is often referred to as a touch screen.

at Other embodiments in which the display device spaced from the touch-sensitive position detection unit is arranged and a virtual, areal allocation of Surface of the position detection unit to the surface the display device is present and the user, for example the display area graphically displayed controls even mental areas of the position detection unit must assign the touch-sensitive position detection unit often referred to as a touchpad.

In 2 is another embodiment of an operating system 1 shown schematically. The same technical features have the same reference numerals in all figures. In this embodiment, the touch-sensitive position detecting unit 5 over a flat trained actuator device 7 arranged. The actuator device 7 includes a plurality of actuator elements 9 , These are formed, for example, as piezo crystals. It is possible by way of this as feedback at different positions of the position detection unit 5 generate different haptic feedbacks. Through this it is possible to give differently recognized user inputs different haptic feedbacks. This is advantageous, for example, when several users simultaneously make user entries via the same operating system. For example, if a recognized user input depends not only on the absolute position of the touch by one of the actuators, but in addition to how long the touching operation persists, it is provided in a preferred embodiment that a parameter of a generated haptic stimulus, the feedback the actuator is output, is varied over time, is preferably varied continuously over time. For example, a vibration with continuously increasing frequency but constant vibration amplitude is output to the user as feedback of an operation, if at this position by a prolonged contact the recognized user input short operation can still be changed into another operation / user input "long touch operation". If a duration of contact is exceeded beyond which the actuation action is recognized as a long touch action, preferably the haptic feedback is abruptly changed. For example, the vibration amplitude is increased suddenly. Alternatively, the frequency could once again be increased suddenly or both parameters of the haptic stimulus, that is, both the vibration frequency and the vibration amplitude are increased at the same time by leaps and bounds. If the actuator device comprises a multiplicity of actuator elements, then such haptic feedbacks can be output to different users at the same time, in each case without influencing the haptic feedback for the other users.

In one embodiment according to 2 in which a variety of actuator elements 9 is provided, as a haptic feedback and a local increase or decrease relative to the plane of the position detection unit can be used as a local haptic feedback.

3 shows a further embodiment of an operating system 1 schematically. In this embodiment, between the touch-sensitive position detecting unit 5 , which is shown here in section, and the display device 8th segmented electrodes 10 and between an electroviscous substance 11 arranged. By applying voltages between the segmented electrodes 10 may be a viscosity of the electroviscous substance 11 be varied depending on the electric field in the electroviscous substance. As a haptic feedback thus the viscosity of the detection device 2 used. Here, it is assumed that the touch-sensitive position detection unit, as well as the segmented electrodes, which are formed for example of indium tin oxide (ITO), represent elastic layers.

In 4 is a plan view of a designed as a touch screen operating system 1 shown schematically. On the visible display area 12 are objects 13 in the form of a virtual carousel 14 arranged. The objects 13 For example, the different titles of a playlist, a CD or Represent something similar. Will that be above the display area 12 the display device arranged touch-sensitive position detection unit 5 by an actuator 3 , which is designed as an index finger, touched, so the carousel rotates 14 around a position like this by means of an arrow 15 is indicated. As haptic feedback is the actuator 3 For example, transmit a vibration having a first frequency and a first amplitude strength. The user additionally touches the touch-sensitive position detection unit with a second actuating element 4 , so this user input is recognized as a continuous turning of the carousel. As long as the touch of the two actuators 3 . 4 , the two fingers, continues, becomes the carousel 14 , shot continuously. The haptic feedback is a vibration with the same frequency, but a significantly increased amplitude strength output. About a variation of a distance 16 between the touch positions 17 . 18 the actuators 3 . 4 on the position detection unit 5 can be a turning speed of the carousel 14 to be changed. If the distance is increased, so for example, the rotational speed of the virtual carousel 14 elevated; As haptic feedback, the vibration is output at a higher frequency. A reduction of the distance 16 thus leads to a slowing down of the rotational speed, which is reported back to the user via a lower vibration frequency than haptic feedback.

at In another embodiment, the rotational speed over set a single actuator. A distance a touch position from a center of the virtual Carousels and, if necessary, in addition a duration of contact set the rotational speed. Will that be an actuator only for a limited time on the touch-sensitive Position detection unit attached, the carousel is in order a position turned. As haptic feedback, for example a vibration with a first frequency and vibration amplitude generated. To indicate that in a longer lasting Actuation detected a different user input For example, the vibration frequency becomes continuous increased over time. Takes the touch longer as a predetermined period of time, so begins a continuous Rotation of the carousel. The haptic feedback is the vibration amplitude elevated. Now, without the touch of the position detection unit to interrupt, the distance of the contact position to the Center of the carousel changed, so changes the rotational speed. The vibration frequency becomes analog the haptic feedback increases or decreases. The user can without a visual control the speed of rotation feel and control.

In 5 a further embodiment of an operating system is shown schematically. This again comprises a trained as a touch screen detection device 2 , On the display surface are two controls 21 . 22 shown. These virtual controls 21 . 22 can be positioned by the user at different positions on the display surface. This is an advantage, for example, in the background, behind the virtual controls 21 . 22 For example, a navigation map (not shown) is shown. In this way, the user can view areas of the navigation map that are otherwise through one of the controls 21 . 22 would be covered. In the illustrated embodiment, a virtual grid exists relative to the display area 24 which is defined by vertical lines 25 and horizontal lines 26 is shown schematically. At the intersections of the vertical and horizontal lines 25 . 26 can use the virtual controls 21 . 22 to be ordered. The user touches the virtual control 21 with a trained as an index finger actuator 3 , A haptic feedback in the form of a vibration at a predetermined frequency and amplitude strength is output to this via an actuator device designed as a vibration device. The user starts the control 21 now over the display area 12 along an X direction, using an arrow 27 is indicated to move, so does the frequency and amplitude, as shown in the below the display area 12 represented graphs 31 and 32 is shown. An upper graph 31 For example, represents a vibration amplitude as the first parameter of the stimulus emitted as feedback plotted against the X direction. The second graph 32 represents a second parameter of the stimulus, for example, the vibration frequency plotted against the X direction. If the operating element is moved away from a grid position R1, so initially decreases the vibration amplitude. The vibration frequency then remains constant. As soon as the vibration element moves into a so-called capture range of a raster position R2, the vibration amplitude increases drastically to signal that the operating element 21 can be moved to this grid position R2. Will the catch area 28 overcoated without touching the touch-sensitive position detection unit 5 to interrupt, so the vibration amplitude decreases again. Once the control 21 over the other control element 22 is placed, both the vibration amplitude and the vibration frequency rise abruptly. As a result, a haptic feedback is conveyed that here, although a grid position 3 is reached, but this is occupied. The fact that the grid position is occupied and a drop of the control element 21 at this grid position 3 is not possible is transmitted by the increased vibration frequency as feedback to the user. So soon the control 21 again from the control 22 is moved away, the vibration amplitude and the vibration frequency decrease again. The vibration amplitude increases again when a further capture range of a grid position R4 is reached, to which the operating element 21 can also be moved by the touch in the wider catch area 29 is ended.

In 6 a further embodiment of an operating system is shown schematically. On the display surface 12 is schematically a navigation map 41 shown. About a wiping control action, in which the one actuator 3 on the touch-sensitive position detection unit 5 put on and then in contact with this via the position detection unit 5 wiping, the navigation map can 41 be moved virtually. For example, a frequency of vibration output as haptic feedback will output adapted to the particular speed imparted to the navigation chart by the swipe. As soon as the touch action ends, the sliding movement slows down quickly. If, in contrast, the wiping movement is carried out simultaneously with two actuating elements, for example two fingers, the card is moved at a higher speed, which is reported back to the user, for example via a higher vibration frequency of the haptic feedback. After an end of the touch action, the card is preferably decelerated slower. This allows a more intuitive operation adapted to a real displacement of a map on a table can be realized.

It is a host of other controls that come with it coupled to a haptic feedback possible. For example can be a zoom of a navigation chart depending on from a spreading movement of two actuators be executed on the position detection unit. ever further the contact positions are spread apart, the more it is zoomed into the map. The size the representation is for example about the vibration amplitude returned to the user as feedback. Will be a distance between the touch positions after being touched down, so a zoom out from the map is effected, which over a decrease in the vibration amplitude feedback as feedback becomes.

at other embodiments, it is provided that, for example via a spreading finger movement in a lower edge area of the Display area is a tilt angle of the map in a 3D rendering mode can be changed.

It It will be understood by those skilled in the art that merely exemplary Embodiments for different detectable Gestures by means of one or more actuators on the touch-sensitive position detection unit executable, as well as the different haptic feedbacks, which are associated with the recognized user inputs described are. In particular, the possibility of individual parameters of the stimulus issued to the user dynamically during to change the action of action, offers the Possibility to alert the user on the one hand do that through the appropriate action in a continuation along a certain direction or over a continuous contact, another modification / continuation the already recognized user input can be effected. hereby the user can be animated, for example, his actuator to withdraw in time from a control element, which different Functions via a short press and a long operation are assigned. Likewise in a such situation encourages the user to his actuator resting on the control element long enough, until the user input as a long-lasting user operation of the operating element is detected. During this period becomes a stimulus parameter, preferably, for example, a vibration amplitude or continuously increasing a vibration frequency until For example, the user input is recognized as a long touch action is. To identify this, one or more stimulus parameters are used changed abruptly.
