Description

The present disclosure relates to a method of operating a passenger display of a motor vehicle. The disclosure likewise relates to a computer program and / or computer-readable medium, a data processing device and a motor vehicle.From the prior art, displays or displays are known which, due to their arrangement, orientation and / or nature, are integrated into vehicles specifically for a passenger. These displays, also called passenger displays (passenger display), thus differ from a central display (central display), for example, arranged centrally in a center console, and from displays for the driver, for example, in the area of a steering wheel and / or as an instrument panel.The passenger displays may be configured to display and / or play various content that is to remain partially invisible to a driver during driving, for example, to ensure traffic safety by avoiding distraction of the driver's attention.To enable this, there are various technologies and implementations, such as gaze detection systems. The gaze detection systems recognize when the driver is looking at the passenger display and in such cases may prevent the driver from seeing the content. This can be realized by temporarily shutting down the passenger display and / or by superimposing a content displayed on the passenger display with an indication that is visually perceptible to the driver. The functionality of the gaze detection systems is designed to make the indications accessible to the passenger only during driving if the driver is potentially distracted.US11908208B2 discloses a driver monitoring system and a method for optimizing the use of the cognitive resources of a user in a vehicle. The system includes in-cabin video cameras, a display device and processing circuitry. The method performed by the processing circuitry includes monitoring the gaze direction from images of the video cameras in the passenger compartment, gradually blurring image areas displayed on the display device and lines that are outside a first range of view of the user of the vehicle, and using the gaze direction to predict whether the user will transition to a new focus range of view that was outside the first range of view. As the user's eyes begin to move, they begin sharpening soft drawn image areas and lines so that the image areas and lines in the new focus field of view reach their full sharpness when the eyes are switched to the new focus field of view.US11042765B2 provides a safety system for playing vehicle-monitored content in a vehicle, which simultaneously minimizes driver distraction. When the driver selects a camera, such as a rear view camera, the vehicle monitored content stream of the camera is displayed on a display in the vehicle. As the driver steers the vehicle, his gaze is monitored. When the driver's gaze indicates that the driver is looking at the display, a timer is started. The timer runs when the driver looks at the display. If the driver's gaze has shown that the driver has continuously looking at the road for more than a certain threshold, the time associated with the vehicle monitored contents is reset to its initial value. When the timer expires, indicating that the driver has paid attention to the vehicle monitored contents for too long without paying attention to the road, the display of the vehicle monitored contents is stopped and the driver is prevented from watching the vehicle monitored contents for a certain time.DE102021122465A1 discloses a method for setting a screen of a vehicle, wherein the screen is provided for a passenger of the vehicle, wherein it is originally provided that at least one display element is displayed on the screen, wherein the at least one display element is analyzed, wherein it is determined whether the at least one display element is dynamic and / or is provided only for the passenger, wherein at least one static display element deviating from the display element originally provided for display is displayed for the at least one dynamic and / or provided only for the passenger from a perspective of the driver in replacement.Despite the advances achieved with the passenger displays, there are aspects in need of improvement. It may be essential that the driver has no possibility to experience the functionality and / or the contents of the passenger display even during the vehicle standstill. This results in a limited user experience and understanding of system behavior and performance, particularly as to criteria for passenger display shut down and / or crossfade with alerts. This can lead to uncertainties or misunderstandings as to how the system works during the driving operation. For example, it may occur that latencies and / or multi-level threshold mechanisms for shutting down the passenger display and / or for displaying instructions are unclear to the driver. It may also be unclear how to show what contents are classified as relevant to safety and thus may lead to shut-downs and / or indications.Against the background of this prior art, it is an object of the present disclosure to specify an apparatus and a method which are each suitable for improving the prior art and for improving at least the abovementioned aspects of the prior art. In particular, the object of the disclosure is to make it possible for users of the motor vehicle to be able to experience the circumstances of the passenger display comprehensively and without restrictions on traffic safety.The object is achieved by the features of the independent claims. The dependent claims include further developments of the disclosure.According to one aspect of the disclosure, the object is achieved by a method for operating a passenger display of a motor vehicle, the method comprising: capturing standstill information indicating a standstill of the motor vehicle; determining, as a function of the standstill information, a switching signal for switching the passenger display into a demonstration mode; and outputting the switching signal for operating the passenger display in the demonstration mode.The method provides a demonstration mode for the passenger display of the motor vehicle. The demonstration mode may allow both a driver and a passenger to experience the behavior of the display during vehicle standstill or standstill, respectively. The demonstration mode allows the driver to learn the contents of the passenger display and obtain a better understanding of system behavior and performance criteria. For this purpose, the standstill information is recorded in order to indicate or indicate the standstill of the motor vehicle. When at a standstill, the motor vehicle is not in the drive, which allows the driver to focus his attention and / or his gaze on the passenger display.The proposed disclosure may provide several advantages. First, the demonstration mode allows the driver and optionally passenger to learn about the functionalities of the passenger display without jeopardizing traffic safety. This leads to better understanding and higher acceptance of the system. Second, uncertainties and misunderstandings about system performance and the criteria for display shut-down or cross-fade can be reduced, resulting in improved user experience. Third, the demonstration mode may provide a valuable opportunity for training and informational purposes, thereby better familiarizing users with the safety features of the motor vehicle. In addition, a seller and / or issuer on a fair may perform the functions of the passenger display based on the demonstration mode.Optionally, the method comprises: detecting a user input for activating the demonstration mode; and the determination and / or the output of the switching signal takes place taking into account the user input. The user input can activate the demonstration mode when the motor vehicle is stationary. The user input and standstill of the motor vehicle can thus be implemented as conditions of activating the demonstration mode.Optionally, the switching signal initiates deactivation and / or modification of a gaze detection. In the demonstration mode, contents that are normally only visible to the passenger can thus be made accessible to the driver. This can be effected by completely deactivating the gaze detection and / or by modifying the gaze detection, for example with respect to temporal threshold values and / or gaze directions.Optionally, the switching signal initiates a predetermined sequence of partially and / or completely turning off and / or disambiguating the passenger display. Alternatively or additionally, the switching signal initiates a predetermined sequence of indicators. Thus, at standstill, the driver may acquire a comprehensive image of potential responses to the turning of his gaze to the passenger display during travel.The demonstration mode is configured to demonstrate functionalities and / or configurations of the passenger display. In this case, functionalities such as the automated disambiguation of contents and / or configurations for setting purposes can be demonstrated or output for this purpose.Optionally, the demonstration mode comprises a plurality of information modules and / or training modules relating to the passenger display. The information and training modules can be integrated into the demonstration mode in order to be able to offer the driver and optionally the passenger an optionally stepwise introduction into the functionalities of the passenger display.Optionally, the switching signal initiates a simulation of an operation of the passenger display during a journey with the motor vehicle. The driver can thus accurately understand the operation of the passenger display during the journey and thereby avoid safety risks due to the standstill of the motor vehicle.According to one aspect of the disclosure, a computer program and / or a computer readable medium is provided. The computer program and / or the computer readable medium comprise instructions which, when the program or instructions are executed by a data processing device, cause the latter to carry out the method according to the disclosure and / or steps thereof. Optionally, the computer program and / or the computer-readable medium comprises instructions which, when the program or instructions are executed by a data processing device, cause the latter to carry out the method steps described as advantageous or optional in order to achieve a technical effect associated therewith.According to one aspect of the disclosure, a data processing apparatus for a motor vehicle is provided. The data processing device is configured to perform the method according to the disclosure. Optionally, the data processing device is configured to perform a method step described as advantageous or optional and / or to implement a method feature in order to achieve a technical effect associated therewith.According to an aspect of the disclosure, there is provided an automotive vehicle including the data processing apparatus according to the disclosure and a passenger display. Optionally, the data processing device of the motor vehicle and / or the motor vehicle is configured to carry out a method step described as advantageous or optional and / or to implement a method feature in order to achieve a technical effect associated therewith.One embodiment is described below with reference to the figures. FIG. 1 schematically illustrates a motor vehicle according to an aspect of the disclosure; FIG. 2 schematically illustrates a flow diagram of a method according to an aspect of the disclosure; and FIG. 3 is a schematic illustration of a computer program and / or computer readable medium in accordance with an aspect of the disclosure.FIG. 1 schematically illustrates a motor vehicle 50 according to an aspect of the disclosure. The motor vehicle 50 is a land vehicle. The motor vehicle 50 is, for example, a passenger car.In addition, FIG. 1 illustrates a driver 11 and a passenger 12 that do not necessarily need to be located in the motor vehicle 50. The driver 11 is a user of the motor vehicle 50 arranged on a driver seat (not shown) The passenger 12 is a user of the motor vehicle 50 different from the driver 11 and arranged on a seat (not shown) different from the driver seat. For example, the motor vehicle 50 defines a longitudinal axis L that corresponds to a forward direction of travel of the motor vehicle 50. The longitudinal axis L divides the motor vehicle 50 into a first side 50 aor driver side and a second side 50 bor passenger side different from the first side 50 a, wherein the longitudinal axis L separates the sides from one another. During travel, the driver 11 is arranged on the first side 50 aof the motor vehicle 50 and the passenger 12 is arranged on the second side 50 bof the motor vehicle 50.The motor vehicle 50 has a data processing device 51. The motor vehicle 50 or the data processing device 51 is configured to carry out the method 100 described with reference to FIG. 2. For this purpose, the motor vehicle 50 has a passenger display 60. Furthermore, the motor vehicle 50 has an interior camera 55, a driver display 58 and a central display 59.The passenger display 60 is disposed on the second side 50 b. The passenger display 60 is configured to output or display visually perceptible information to the passenger 12.The driver display 58 is disposed on the first side 50 a. The driver display 58 is configured to output or display visually perceptible information to the driver 11.The central display 59 is arranged on the first side 50 aand the second side 50 b, for example in the region of a central console of the motor vehicle 50. the central display 59 is configured to output or display visually perceptible information to the driver 11 and the passenger 12.In this case, the driver display 58, the central display 59 and the passenger display 60 can be display devices which are separate from one another and which can also be controlled and / or operated separately from one another. Alternatively, the driver display 58 and the center display 59, the center display 59 and the passenger display 60, or the driver display 58, the center display 59 and the passenger display 60 may be formed as portions of a common display device that extends perpendicular to the longitudinal axis L through the motor vehicle 50.The interior camera 55 is configured to capture at least image data relating to the driver 11, from which image data a viewing direction of the driver 11 can be determined by image processing. For this purpose, for example, a head pose, a nose vector and / or an alignment of pupils of the driver 11 can be determined. The interior camera 55 is thus part of a view recognition system.The data processing device 51 is configured to acquire standstill information 65 indicating a standstill of the motor vehicle 50. The standstill information 65 can be transmitted to the data processing device 51, for example, via a vehicle bus, in particular a CAN-BUS, of the motor vehicle 50. The standstill information 65 indicates that the motor vehicle 50 is at a standstill.The data processing device 51 is configured to determine a switching signal 70 for switching the passenger display 60 into a demonstration mode 61 as a function of the standstill information 65. In this case, the data processing device 51 can check the presence of the standstill information 65 and thus the standstill of the motor vehicle 50. The standstill information 65 or the standstill of the motor vehicle 50 are preconditions for switching the passenger display 60 into the demonstration mode 61.The data processing device 51 is configured to output the switching signal 70 for operating the passenger display 60 in the demonstration mode 61. For this purpose, the data processing device 51 and the passenger display 60 are connected to one another in terms of communication technology. The passenger display 60 can thus receive the switching signal 70 and thereby be switched to the demonstration mode 61.The data processing device 51 is configured to acquire a user input 66 for activating the demonstration mode 61. The user input 66 can be detected as touch input, for example, via one of the driver display 58, the central display 59 and the passenger display 60, and transmitted to the data processing device 51. The user input 66 can thus be an additional prerequisite for switching the passenger display 60 into the demonstration mode 61. The determination and / or the output of the switching signal 70 is then carried out taking into account the user input 66.The switch signal 70 initiates a simulation of operation of the passenger display 60 during travel with the motor vehicle 50. In demonstration mode 61, the contents that are normally visible only to passenger 12 during the trip are made accessible to driver 11. This can be done by deactivating the gaze recognition and / or by simulating the typical display deactivation or superimposition. For this purpose, the switching signal 70 initiates a deactivation and / or modification of a gaze detection. The driver 11 can thus learn the various contents and behavior of the system without jeopardizing traffic safety.The switching signal 70 initiates a predetermined sequence of partially and / or fully disabling and / or obscuring the passenger display 60. The switching signal 70 initiates a predetermined sequence of indications. Additionally, demonstration mode 61 may simulate various scenarios to demonstrate system behavior. For example, the system could show how it responds to different viewing directions of the driver 11 by switching off and / or blending the display contents accordingly. These simulations allow the driver to develop a comprehensive understanding of the criteria that the system uses to recognize driver gaze.Demonstration mode 61 includes a plurality of information modules and / or training modules related to passenger display 60. Information and training modules could be incorporated into demonstration mode 61 that provide driver 11 and optionally passenger 12 with a stepwise introduction into the functionalities of the passenger display. Demonstration mode 61 is configured to demonstrate functionalities and / or configurations of passenger display 60. This could be done by interactive tutorials and / or illustrative videos illustrating system performance and associated security actions.The motor vehicle 50 and the method 100 thus implement the demonstration mode 61 for the passenger display 60 of the motor vehicle 50. the demonstration mode 61 can be activated manually by the user input 66 or automatically when the vehicle is stationary, i.e. when the standstill information 65 is present. In the manual mode, the driver 11 or passenger 12 could activate the demonstration mode 61 through a user interface, such as via a central infotainment system and / or directly via the passenger display 60.FIG. 2 schematically illustrates a flow diagram of a method 100 according to an aspect of the disclosure.
