Description

Vehicle display arrangement, vehicle, method of operating a display arrangement of a vehicle, computer program product

Technical Field

A display arrangement of a vehicle is disclosed, the display arrangement comprising at least one display configured to display content to a driver and/or passenger of the vehicle, wherein the display comprises a privacy screen; a method of controlling such a display arrangement; and a computer program product.

Background

Display arrangements of the above-mentioned type are generally known in the art. In recent years, there has been a great progress in expanding the viewing angle of flat panel displays such as liquid crystal displays. However, in some cases, a large angle viewing range of a screen may be a disadvantage. Information such as banking data or other private details and sensitive data is increasingly presented on screens available in public space, such as mobile devices. Thus, the user needs to have some control over who can see these sensitive data. It is desirable to be able to select between a wide view angle that shares display information with others and a narrow view angle that is needed to preserve the privacy of the display information.

Similar problems are encountered in vehicles such as automobiles: when a vehicle is traveling, the driver must not be distracted by image content such as digital entertainment, and a front seat passenger and/or a rear seat passenger want to view such content during boarding. This is particularly important during the night, as light pollution may cause the driver's eyes to adapt to the vehicle interior brightness, which may reduce the ability to identify potential hazards in low contrast and dark environments. This requires a screen that can be switched between corresponding display modes.

US 10,838,133B2 discloses a screen provided with a transmission image generator provided with a number of pixels operable in at least two modes of operation, B1 for a free viewing mode and B2 for a limited viewing mode; and having an illumination device comprising a backlight having a planar extension and radiating light over a limited angular range, a plate-like light guide being arranged in front of the backlight and provided with a plurality of coupling-out elements on one of a plurality of large surfaces and/or within its volume, the light guide being transparent for at least 70% of the light emitted by the backlight; and a plurality of light sources arranged laterally at a plurality of edges of the light guide. In mode B2, the backlight is turned on and the plurality of light sources are turned off, and in mode B1, at least the plurality of light sources are turned on. In interaction with the transmission image generator, the illumination device constitutes an advantageous screen allowing the plurality of modes of operation.

However, there are situations in the vehicle where the driver or passenger may not be able to recognize the surrounding situation, such as a pedestrian passing a vehicle parked in a public place. The driver or passenger may not be aware of the pedestrian's ability to view the screen content at that time, so they may easily forget to enable (activating) a restricted viewing mode so that the pedestrian can see sensitive content such as passwords.

Disclosure of Invention

It is therefore an object to provide a display arrangement for a vehicle and a method of operating the same which can be automatically switched to a limited viewing mode as the case may be without requiring user actuation (get active).

The invention is disclosed in the independent claims 1, 6, 7 and 12. Further embodiments are disclosed in the various dependent claims.

A display arrangement of a vehicle is disclosed, the display arrangement comprising at least one display configured to display content to a driver and/or passenger of the vehicle, wherein at least one view limiter is associated with the at least one display, the view limiter being switchable between at least a non-restricted mode in which a view angle of the display is not restricted and a restricted mode in which the view angle of the display is restricted, the view limiter covering at least parts of the display, a controller for controlling the view limiter to switch between at least the non-restricted mode and the restricted mode, the controller comprising a processor configured to calculate a privacy value based on at least one context factor (context factor) input into the processor, wherein the controller is configured to switch the privacy limiter into the restricted mode if a privacy value threshold of the privacy value calculated by the processor is exceeded.

The vehicle may be a car, a truck, a bus, or the like.

The display may be a flat panel display using technology such as LCD, OLED or Micro-LED. It may be mounted on an instrument panel, an armrest or a headrest of the car. It may be detachable and/or rotatable.

The view limiter may have more than two different modes, for example modes with different viewing angles depending on various situations, various preferences or various presets. In an exemplary arrangement, a non-limiting viewing mode (unrestricted viewing mode) may allow for a natural viewing angle of the associated display. A restricted viewing mode may restrict the field of view to an angle of 20 ° relative to a normal axis of the display or an axis oblique to the normal axis of the display. The viewing angle may be different in different directions of the display, may be wider in a vertical direction, and may be narrower in a horizontal direction. Furthermore, the viewing angle may be movable in a horizontal and/or vertical plane, for example, to limit the viewing angle of a driver or a front seat passenger depending on who is using the display.

The field of view limiter may be constructed using different techniques. One suitable technique uses switchable polarizers. Another suitable technique uses light guides that have elements that can switch optical properties. Another technique uses diffractive elements. If optical elements are used that are sensitive to electrical characteristics, such as an electric field, such optical elements can be switched quickly using circuits. Such optical elements may be switchable liquid crystal displays. The field of view limiter may comprise a plurality of layers, some of which may be active and others may be passive, depending on the embodiment selected.

The field of view limiter may cover the entire viewable surface of the associated display or may cover portions of the display. In the latter case, some of the viewable area of the display is not covered by the view limiter, and therefore will remain viewable regardless of the mode of the view limiter. This allows content to remain visible in a wider field of view, for example making it important for other passengers of the vehicle or the driver. Thus, it is feasible for a passenger to view a video on the display, while the driver may still see some other information, such as navigation information, on the screen.

The view limiter may be activated over its entire surface or selected areas thereof, for example, only concealing areas where a password is supposed to be entered.

The privacy value calculated based on at least one context factor allows an automatic evaluation as to whether the restriction mode should be enabled. The view limiter automatically switches to a limiting mode once the privacy value exceeds the threshold. Individual users, drivers or passengers of the display cannot forget to switch the display to the restricted mode.

For example, if a passenger is required to enter a password in a parking lot, the controller may automatically activate the restricted mode of the view restrictor such that the entered password is not visible to personnel surrounding the vehicle. Limiting the view angle for the same purpose may not be necessary when the vehicle is traveling. Another example is to display a video on a front central display of the vehicle, typically used as the primary infotainment display (main infotainment display), which the driver should not see while driving to avoid distraction, while making the video visible to the driver while the vehicle is parked may be inconsequential.

In a first further embodiment, the controller may be configured to switch the view limiter to the unrestricted mode if a privacy value threshold of the privacy value calculated by the processor is not exceeded.

This allows many passengers to view content with the privacy value low enough, for example, to display a cabin temperature in summer to prevent animals from being left in a car.

In a further embodiment, the display arrangement comprises more than one display, wherein a privacy value for each display is calculated separately, wherein the controller is configured to switch a view limiter of at least one of the plurality of displays into a limiting mode if the privacy value of the display exceeds the privacy value threshold.

Vehicles may include more than one display, such as a driver display, a front center display, and/or rear seat displays. All of these displays may display different content at the same time, so the need for privacy may vary from case to case.

In yet a further embodiment, at least one sensor is connected to the controller, wherein a sensor output is used as a context factor or for calculating a context factor.

Depending on the sensor, it may be desirable to convert the raw sensor output to a more suitable format, such as if a sensor provides a class of values, such as a current or voltage, it needs to be converted to a digital value that is representative of the respective analog sensor output.

Using the sensor output as a context factor may provide repeatable behavior of the display arrangement, so that in the same case the behavior of the display arrangement will be the same.

In yet a further embodiment, wherein the at least one sensor is at least one of a position sensor, a seat occupancy detection sensor, a driving status sensor, a clock, or a light sensor.

A position sensor may be, for example, a GPS sensor of a navigation system of the vehicle. Such a sensor may determine the position of the vehicle on a map. The map may include clusters of different regions with different context factors. For example: a parking lot, a gas station, a charging station, a city road, or the like may have a higher privacy requirement than an off-road, an expressway, or the like. For example, if the driver needs to enter an address in the navigation system, which typically occurs when the car is parked in a city, a person outside the vehicle may be prevented from reading the address.

A seat occupancy sensor may help determine which seats of the vehicle are occupied. For example, if a person, such as a child, is present in the rear seat and the passenger wants to watch a movie, the view limiter can be switched to the limiting mode and the child in the rear seat is not disturbed, in particular at night.

A driving status sensor, such as a speed sensor or a driving mode sensor, e.g. automatic driving and manual driving, may be used to determine whether the driver is suitable to view the content displayed on the screen without distraction from the task of driving the vehicle.

Due to the high contrast of the screen content with the surroundings of the vehicle, a clock and/or a light sensor can be used to determine the daytime and nighttime times and thus what the visible content from outside the car is.

In a further embodiment, the controller is connected to or comprises a content classifier module to classify content to be displayed on the at least one display, wherein the content classifier module is configured to calculate a privacy value based on the content to be displayed on the at least one display.

The content classifier module may be part of a computer program product running (run) on the processor, or it may be a separate software or hardware module that is part of the controller or external to the controller.

The content classifier may determine whether the respective content is sensitive, such as a password, PIN code, address or the like, or what type of content should be displayed, such as video like a movie. In addition, the content classifier may classify content according to audience attributes such as age. Content with restricted recommendations may then only be visible in a restricted viewing mode.

A first independent aspect relates to a vehicle provided with at least one display arrangement as described above.

The vehicle may be a car, a truck, a bus, or the like.

Another independent aspect relates to a method of controlling a display arrangement of a vehicle, the display arrangement comprising at least one display configured to display content to a driver and/or passenger of the vehicle, wherein at least one view limiter is associated with at least one display, the view limiter being switchable at least between a non-limiting mode in which a view angle of the display is not limited and a limiting mode in which the view angle of the display is limited, wherein the view limiter covers at least parts of the display, wherein a privacy value is calculated in a processor, the processor being part of a controller for controlling the view limiter, the privacy value being calculated based on at least one context factor input into the processor, wherein the controller switches the view limiter into the limiting mode when a privacy value threshold of the privacy value calculated by the processor is exceeded.

The view limiter may be activated over its entire surface or selected areas thereof, such as to hide only an area where a password is supposed to be entered.

Calculating the privacy value based on at least one context factor allows an automatic assessment as to whether the restriction mode should be enabled. The view limiter automatically switches to a limiting mode once the privacy value crosses the threshold. Individual users of the display, the driver or the passenger, cannot forget to switch the display to the restricted mode.

For example, if a passenger is required to enter a password in a parking lot, the controller may automatically activate the restricted mode of the view restrictor such that the entered password is not visible to personnel surrounding the vehicle. Limiting the viewing angle for the same purpose may not be necessary when the vehicle is traveling. Another example is to display a video on a front central display of the vehicle, which is typically used as the primary infotainment display, which the driver should not see while driving to avoid distraction, while making the video visible to the driver while the vehicle is parked may not be of any importance.

In a further first embodiment, the display arrangement comprises more than one display, wherein a privacy value for each display is calculated separately, wherein the controller switches a view limiter of a display into a limiting mode if the privacy value for the display exceeds the privacy value threshold.

In yet a further embodiment, the at least one context factor comprises at least one of a location factor, a seat occupancy status factor, a driving status factor, a time factor, and/or a content category of content to be displayed on the display.

A position sensor may be, for example, a GPS sensor of a navigation system of the vehicle. In this way the position of the vehicle on a map can be determined. The map may include clusters of different regions with different context factors. For example: a parking lot, a gas station, a charging station, a city road, or the like may have a higher privacy requirement than a general road, an expressway, or the like. For example, if the driver needs to input an address in the navigation system, a person outside the car may be prevented from reading the address.

A seat occupancy sensor may help determine which seats of the vehicle are occupied. For example, if a rear seat is occupied, such as a child, and a passenger wants to watch a movie, the view limiter may be switched to the limited mode and the child on the rear seat is not disturbed.

A clock or a light sensor may be used to determine the circadian time and thus how visible content is from outside the vehicle and determine a degree of light pollution within the vehicle.

The content category may indicate whether the respective content is sensitive, e.g. whether a password, PIN code, address or the like is to be displayed, or what type of content should be displayed, such as video like a movie.

In addition, the content may be categorized by audience attributes such as age. Content with many restricted recommendations may only be visible in a restricted viewing mode.

In a further embodiment, more than one context factor is used to calculate the privacy value, wherein each context factor is weighted and combined.

The combination may include additions and/or multiplications, e.g.

v _p ＝Σ _i f _i ×w _i

Wherein: v _p Privacy value; f (f) _i =context factor, w _i =context weight.

The context factors may be discrete or continuous values, depending on the type of context factor. For example, the location-dependent context factor may typically be quite discrete and the illumination-dependent context factor may be continuous.

The context factors and context weights may be part of a look-up table (look-up table). The look-up table may be preset. The lookup table may be configured by a user or a service station of the vehicle. A learning algorithm may be used to learn about the driver's and/or passenger's preferences for certain conditions.

Some weighted context factors may be large enough to trigger a switch to the privacy mode alone, e.g., if a password needs to be entered, other factors may be so small that only a combination of cases will result in a switch to the privacy mode, e.g., watching a movie with limited audience ratings while charging the car and watching a movie without such recommendations while charging, or watching the first mentioned movie while driving.

In a further embodiment, the calculation of the privacy value is performed continuously, wherein the view limiter is switched to the non-limiting mode when the privacy value is lower than or equal to the privacy value threshold.

Once the situation changes, such as the position or content, the view limiter can be switched in the most appropriate mode.

Another independent aspect relates to a computer program product stored on a computer-readable non-transitory storage medium, the storage medium comprising a computer-readable program for causing a computer processor to control execution of an application program, the application program implementing the method according to the method described above.

Further features, details and characteristics of the invention are provided in the claims, the drawings and the following description of embodiments. It is understood that the features mentioned before and as explained below are applicable not only to the described combinations but also to other combinations or as individual features without departing from the scope of the invention.

The field of view limiter may include a technique of gradually limiting the respective fields of view. Their center axis of view may be offset from a normal axis of the display and/or the center axis may be movable to limit the view to a side. It is also possible to have different viewing angles in the horizontal and vertical directions.

Drawings

The invention will be explained in more detail below with reference to the accompanying drawings, which show, among other things, features that are essential to the invention, in which:

FIG. 1 shows an automobile provided with a display arrangement;

FIG. 2 shows the display arrangement of FIG. 1 in more detail;

fig. 3 shows a flow chart of the method.

Detailed Description

Fig. 1 shows a motor vehicle 2 with a display arrangement (display arrangement) 4 (elements in the dashed box).

The display arrangement 4 comprises a plurality of displays 6, 8 and 10, wherein display 6 is a central display located at the dashboard of the car 2 and in front of a driver 12 and a passenger 14, so that both the driver 12 and the passenger 14 are in comfortable line of sight. The central display 6 is a graphical display that is used as part of a human-machine interface of the car 2 and that can display different types of content, such as car status information, maps, media player information, entertainment content, and the like. The display 6 may display a number of videos. The plurality of displays 8 and 10 are a plurality of rear seat entertainment displays.

The plurality of displays 6, 8 and 10 may use the same or different display technologies, such as LCD, OLED or micro-LED.

The driver 12 should not be exposed to content such as video while driving the car 2, as such content may distract the driver 12 and may affect the operational safety of the car 2. In many countries, displaying distraction content on the screen while driving is legally prohibited.

The plurality of displays 6, 8 and 10 are equipped with respective view limiters 16, 18 and 20. The plurality of view limiters 16, 18, 20 may be switched between a non-limiting mode and a limiting mode, as shown in connection with the display 6. The view limiters 16, 18, and 20 include multiple layers with switchable optical properties.

The view limiters 16, 18, and/or 20 may include techniques to gradually limit the respective views. Their central axis of the field of view may be offset from a normal axis of the display and/or the central axis may be movable to limit the field of view to a side. It is also possible to have different viewing angles in the horizontal and vertical directions.

Two view angles alpha are displayed, a limited view angle alpha _r An unrestricted view angle alpha _u . The limited view angle alpha _r Associated with a restricted mode and the unrestricted view angle alpha _u Associated with a non-limiting mode of the view limiter 16. The limited view angle alpha _r The side facing the passenger 14 is oriented and inclined to a normal axis (not shown) of the display 6.

A controller 22 is connected to the plurality of displays 6, 8, 10 and the plurality of view limiters 16, 18, 20. The controller 22 includes a processor 24 and a non-transitory storage medium 26. The processor 24 is configured to load and execute a computer program product 28 stored in the non-transitory storage medium 26.

The controller 22 is also connected to several sensors, a driving status sensor 30, a GPS sensor 32, a light sensor 34 and a plurality of seat occupancy sensors 36, 38, 40 and 42. The controller 22 is also connected to a clock 44.

The plurality of sensor inputs of the plurality of sensors 30 through 44 are converted to a plurality of context factors. This conversion may occur on the sensor side of the plurality of sensors 30 to 44 or it may occur on the controller side of the controller 22. The conversion may produce a continuous value or a discrete value, such as a speed (continuous) or a seat occupancy condition (discrete) of the vehicle 2.

The plurality of context factors are then used to calculate a privacy value, e.g. in combination withAs depicted in the figures. If the privacy value v _p Exceeding a given privacy value threshold v for a particular screen content _t The controller 22 causes one or more of the plurality of view limiters 16, 18, or 20 to switch to a limited mode to protect the information displayed on the respective display 6, 8, or 10.

Fig. 2 shows the display arrangement 4 in more detail.

On the display 6, the content 44 is currently presented. The content 44 is a video. The data of the content 44 is stored in a storage space 46 of the storage medium 26 of the controller 22.

The content 44 is fed through a content classifier 48. The content classifier module 48 classifies the content 44 according to its attributes, such as content type or content rating. The content classifier module 48 is connected to the processor 24 and feeds content type categories as a context factor to the processor 24.

In other embodiments not shown but included herein, the content classifier 48 is integrated into the computer program product 28 and executed in the processor 24.

An external media source 50, such as a handheld consumer device, may also be connected to the controller 22 and the content classifier 48 such that content stored on the media source 50 may also be classified and displayed in a non-limiting mode or in a limiting mode. The connection between the external media source 50 and the controller 22 may be wired or wireless using one of the known protocols, such as bluetooth or WLAN.

The sensor data of the plurality of sensors 30-42 is fed to a converter 52, which converter 52 converts raw or pre-processed sensor data into a plurality of context factors. The plurality of processed context factors are fed into the processor 24.

In other embodiments not shown but included herein, the conversion may be partially carried out on the sensor so that a converter in the controller 22 is not required.

The display 6 further comprises a switch 54 for manually switching between the restricted mode and the unrestricted mode. Such a switch 54 may be positioned differently in different embodiments, or it may not be present in some other embodiments.

The processor 24 is based on a plurality of context factors f _i Calculating a privacy value v _p Each of the context factors has a unique weight w _i Weighted:

v _p ＝Σ _i f _i ×w _i

for example, a privacy value threshold v _t Is defined such that if v _p >v _t The view limiter 16 is triggered to enable the limiting mode. If v _p ≤v _t The view limiter 16 is triggered to enable the non-limiting mode.

Multiple weights w _i May be stored in a look-up table stored in the storage medium 26. The plurality of weights w _i Preset and/or editable by user input, update or by machine learning. Such a lookup table may have the following exemplary format:

TABLE 1

Input device	Context factor range	Weighting of
			Driving state	0、0.5、1	10
Rear seat for occupying seat	0、1	5
			Position of	0 to 1	10
Content type	0 to 1	10
			Light of lamp	0 to 1	3
…	…	…

The privacy value threshold v _t Can be set to 9, i.e. if the privacy value v is calculated _p Beyond a value of 9, each view limiter 16, 18 and/or 20 is switched to a limiting mode.

Example 1

When the car 2 is driven in a manual driving mode by the driver 12, a video is displayed on the display 6.

The weight of the driving state is then 1, v _p Equal to 10, so it exceeds the privacy value threshold v _t The view limiter 16 is switched to a limiting mode.

Example 2

A subscriber station is required to enter a password at a parking lot. The content-type context factor is equal to 0.5 and the locality context factor is equal to 0.7.v _p Then 13 and the view limiter 16 is switched to the limiting mode.

Example 3

The passenger 14 wants to watch an action movie while a passenger sits in a rear seat behind him, which is associated with a seat occupancy sensor 42.

The seat occupancy context factor is then 1, wherein the content type context factor is 6, thus v _p Equal to 11 and the view limiter 16 is switched to a limiting mode.

Example 4

The passenger 14 wants to watch a child program while a passenger sits in a rear seat behind him, which is associated with the seat occupancy sensor 42.

The seat occupancy context factor is then 1, wherein the content type context factor is 1.v _p Then equal to 6 and the view limiter 16 is switched to the non-limiting mode.

Fig. 3 shows a flow chart of a possible implementation of the method in a computer program product.

In contrast to the example shown above, each weighted context factor alone may trigger the enablement of the restricted mode.

After the start, the controller 22 checks whether the display is active. While this is generally applicable to the central display 6, the rear entertainment displays 8 and 10 or armrest displays are typically only enabled when a rear passenger wishes to use the respective display 8 or 10.

The controller 22 then checks whether it is daytime or nighttime. If at night, the controller checks if there are other passengers in the car 2. If this is the case, the view limiter 16 is set or switched to a limiting mode to reduce the brightness in the car.

If this is not the case, the controller 22 checks whether the car 2 is located at a place of interest, such as a parking lot, a gas station, a charging point or the like. If this is not the case, the controller 22 continuously checks whether the vehicle 2 is currently parked in a public area. If this is the case, the controller 22 checks via the content classifier module 48 whether the screen content 44 is sensitive, such as a password, a PIN, an address, a movie or a video game. If this is the case, the view limiter 16 is set or switched to a limiting mode. If this is not the case, the view limiter is set or switched to a non-limiting mode.

If the vehicle 2 is located at a site of interest (a point of interest), the method jumps to the step of checking for:

the process is repeated at regular intervals so that the view limiter can switch between a limited mode and an unrestricted mode depending on the current situation.

The present invention is not limited to the above-described embodiments, but can be modified in various ways.

All features and properties disclosed in the claims, the description and the drawings, including construction details, spatial directions and flow steps, may be important for the invention disclosed herein, either alone or in any meaningful combination.
