A method for reproducing possible or already done, by an input unit (13) to be detected or already done operator inputs in a motor vehicle (1), which serve the operation or the control of an assistance or information system of the motor vehicle (1), which operator inputs in one Display (2, 7) are displayed, wherein the operating inputs are displayed on a lens root display (9).

Description

The invention relates to a method for reproducing possible or already done, to be detected by an input unit or already done operator inputs in a motor vehicle, which serve the operation or the control of an assistance or information system of the motor vehicle, which operating inputs are displayed in a display.

Motor vehicles are known from the prior art, which include various assistance or information systems such as driver assistance, navigation and / or infotainment systems. During operation of these assistance and information systems, information is typically reproduced on the vehicle interior to inform the vehicle occupants.

Expediently, the display units provided for display today comprise liquid crystal screens, so-called displays. Such displays can be used to display a variety of information, in particular state variables of the motor vehicle, such as a vehicle speed, an engine speed or the like. Furthermore, outputs of the navigation system can be displayed, for example in the form of a digital road map.

Such displays are typically integrated in a vehicle interior trim, in particular dashboard. Driver-relevant information is displayed, for example, via a combination instrument having one or more displays, which are arranged behind a steering wheel of the motor vehicle. Furthermore, motor vehicles are known in which a further display is additionally arranged in the region of a center console.

For the operation and control of the assistance or information system, the detection of user-side operating inputs is necessary. For example, in order to activate a route guidance function, a navigation destination must be preset to a navigation system at the start of the journey so that a route from the current location to the destination can be calculated and displayed on a display. Serve for this purpose input units, which are designed for voice detection. An evaluation unit connected to the input unit is designed for voice recognition, so that, in particular, voice commands predetermined by the user can be interpreted.

Furthermore, motor vehicles are known which have input units which are equipped to detect the operator input with a touch-sensitive surface. Such input units are typically referred to as touchpad or touchscreen and are designed so that a, in particular exerted by a finger movement of a user, pressure on the touch-sensitive surface can be detected. Accordingly, the finger movement of the user is recorded and then evaluated to capture the operator input. In this case, it may be provided, in particular, to recognize patterns or signs predetermined by the finger movement, as it were handwritten. The evaluation unit connected to the input unit is designed to recognize such patterns.

From the field of mobile telecommunications equipment, in particular in the field of so-called smartphones, it is known to establish a connection with a corresponding service, in particular a service of the Internet, for pattern recognition. Thus, the connection to the evaluation unit for voice and / or pattern recognition does not have to be constantly provided, but can also be set up if required.

Furthermore, it is known, for example in the context of infotainment systems, to activate functions, for example a search function for media contents or the like, depending on an operator input. The search can be carried out on a local storage medium in the motor vehicle or require a connection to a network or to the Internet.

Recently, alternative display concepts for motor vehicles are proposed in which, for example, driver-relevant information is projected directly onto a windshield of the motor vehicle. Such display units are in particular intended to display status data of the motor vehicle such as the instantaneous vehicle speed.

For example, this is off WO 2008/040899 A1 a display unit having a display surface, which is disposed in an upper portion of the dashboard in the vicinity of a lower-side boundary of the windshield has. The display unit has an opaque coating onto which information is projected by means of a projector during operation.

Furthermore, it is off DE 397 22 094 U1 a display unit is known, which is designed as a liquid crystal display and is arranged directly on or in the windshield.

Based on this prior art, it is an object of the present invention, an improved method for reproducing possible or indicate already made operator inputs, in particular a possible by the input possible distraction of a driver of the motor vehicle is reduced.

The object is achieved by a method of the aforementioned type, wherein according to the invention the operator inputs are displayed on a windscreen display.

In this case, a lens root display is understood to mean a display unit which is arranged on a lower boundary of a windshield and extends at least over a width of the windshield. The lens root display preferably comprises a liquid crystal display (LCD) or an OLED display, which is formed band-shaped. Due to the large spatial extent, the lens root display can be used to display or reproduce a variety of information. In another embodiment, the lens root display is designed as a projection display.

Preferably, the lens root display extends over at least 50% of the width of the windshield, more preferably over 50% -70% of the windshield width.

When presetting operator inputs for an assistance or information system of the motor vehicle, a considerable distraction of the driver may occur. In particular, there is the danger that the driver will be distracted from the current traffic situation when operating the information and / or assistance system. If an operator input is evaluated by means of pattern recognition, the driver would typically like to check whether the finger movements recorded, for example, via a touch-sensitive surface were correctly interpreted. The display of the already completed operator input on the windscreen display minimizes the distraction of the driver, since the relevant information is displayed directly in the driver's peripheral field of view. Thus, the driver must turn his eyes only slightly and briefly from the traffic to check the completed operating instructions.

The same applies to the reproduction of possible and yet to be detected operator inputs for controlling the assistance or information system. Oftentimes, the specification of a large number of consecutive operator inputs is necessary for controlling the assistance or information system. In motor vehicles that are designed for voice detection or speech recognition, the control of the assistance or information system is typically carried out in the context of speech dialogues. In particular, in cases where the user is not yet familiar with the speech dialogue system, it makes sense to issue the corresponding possible and yet to be detected operator inputs or voice commands vehicle inside. Here, too, it is provided to display the possible still-to-be-detected operating inputs in the windscreen display, so that in particular the driver can easily find and read the voice commands.

The operator input is thus expediently as a voice input or as a character input, which takes place via a rotary-push-button a touchpad or a touchscreen. When using the rotary-push-dial, for example, characters or letters are displayed in the form of a list on a display of the motor vehicle, in particular on the windscreen display, which are then selected according to the user to create the operating input. The acquisition of operating inputs via the touchpad or the touchscreen has the advantage that the user can select the desired characters from the displayed list in a particularly simple manner by means of appropriate finger movements.

Furthermore, it is also provided to capture and record the finger movement of the user by means of the touchpad or the touchscreen, the detected pattern being interpreted and recognized as characters, in particular as letters or numbers. Thus, the detection of a haptic vorgebaren operator input is enabled, which allows a particularly comfortable operation by means of appropriate finger movements.

The pattern corresponding to the finger movement is recognized by means of an evaluation unit designed for this purpose. The evaluation unit is implemented in one embodiment of the motor vehicle side. Alternatively, for pattern recognition, the connection with an external service, in particular with a service of the Internet, can be provided.

The same applies to the recognition of voice input. According to a preferred embodiment of the invention, the motor vehicle thus has at least one evaluation unit which is designed to evaluate and recognize the voice inputs detected by means of the input unit. In an alternative embodiment, it is provided to transmit the pattern recorded as a voice input to an external service which recognizes and evaluates the voice input.

Thus, a string is advantageously displayed in the display of the already completed operating input, which corresponds to the pattern recognition or speech recognition. The string thus corresponds to the part of the the evaluation unit connected to the input unit recognized voice input and / or character input. Accordingly, when using the external service for pattern or speech recognition, a data record containing the character string is transmitted to the motor vehicle by means of suitable communication units.

In one embodiment, an infotainment system of the motor vehicle is controlled via the operating inputs. Alternatively, it is provided to control a navigation system of the motor vehicle via the operating inputs. In this case, a search for a content associated with the character string is performed. For example, search is made for media content, such as music titles or artist names or locations for specifying a destination for the navigation system. Likewise, in order to carry out the search, it may in turn be provided to provide a connection to a computer network, in particular to the Internet. Corresponding search results are clearly displayed on the lens root display, so that they are displayed in particular in the peripheral field of vision of the driver and thus can be detected very quickly.

The establishment of the connection to the network, in particular for carrying out the search for the Internet, has the advantage that resources can be accessed in a gentle manner on a multiplicity of differently designed external services without these services having to be implemented on the vehicle side. In particular, the costly upgrade (upgrade) of motor vehicle-side program means, in particular software, is thus avoided.

According to various embodiments of the invention, the content associated with the character string which corresponds to the recognized operator input is a media content, in particular an audio content or video content and / or contact and / or address data, in particular telephone numbers.

In speech acquisition, it is provided to display a speech command of an information and / or assistance system designed for speech dialogue as a possible operator input to be recorded on the pane root display. In particular, the driver can be instructed while driving to specify the necessary voice commands. The expansion of the lens root display makes it possible to display a suitable size so that the voice command (s) displayed there can be easily read.

The invention further relates to a motor vehicle having a lens root display for displaying information, an input unit for detecting user-side operating inputs and a control unit for controlling the lens root display. The motor vehicle is designed to carry out the method already explained for the inside of the vehicle-inside reproduction of possible or already done, to be detected by the input unit or already made operator inputs. The reproduction of the operating inputs on the windshield display, which is arranged on the lower edge of the windshield, minimizes the distraction of the driver from the driving, since he has to avert his eyes only insignificantly short time.
