Abstract
Description
[0001] vehicle
[0002] The invention relates to a vehicle of the type defined in more detail in the preamble of claim 1.
[0003] Vehicles such as cars have a wide variety of configurable components. For example, a seat can be adjusted to the body size of a vehicle occupant, the ventilation level and air temperature of an air conditioning system can be set, an audio source can be selected via an infotainment system to tune into a preferred radio station and select the preferred volume, a suspension tuning can be made harder or softer, display options for a graphical user interface can be changed, and so on. Corresponding configuration parameters can also be grouped together in the form of a user profile. If different people use the same vehicle, each person can select their respective user profile, which allows all configuration parameters to be quickly and easily changed to the person's preferred settings.By activating a user profile, for example, the vehicle's driver's seat is adjusted to the person's height, the vehicle's exterior mirrors are adjusted accordingly, and the user's Bluetooth-connected smartphone is selected as the audio source. This improves comfort for the vehicle's occupants.
[0004] The same user can also create different user profiles and select the currently preferred user profile depending on the situation. For example, a user might prefer a firm sports suspension setting and a radio station broadcasting news on their daily commute, while a comfortable suspension setting and audiobook playback might be preferred on a family vacation. Typically, a user profile is selected via the vehicle's infotainment system, usually via a touch-sensitive display. DE 102019 132 403 A1 discloses a method for automatically selecting a user profile in a vehicle.The method provides that the vehicle reads a digital key parameter carried by a vehicle user from a vehicle key, for example, a radio key or a corresponding key file on a smartphone, and independently selects the user profile based on the key parameter, taking into account components of the key parameter that are not used to start the vehicle. The vehicle can also consider additional context information, for example, whether music is being played on a mobile phone or a chat is taking place, which user profile was frequently selected in the past at a particular time or time of day, how many vehicle occupants are currently in the vehicle, what the current weather is and / or what time of year it is, and the like.The vehicle can also be equipped with biometric sensors, such as a scale, a microphone, or a camera, that allow the vehicle to uniquely identify users. The vehicle can also use these to uniquely assign user profiles to a specific individual.
[0005] Projectors are also commonly used in vehicles to illuminate the vehicle's surroundings. This makes it easier to find dropped objects at night, for example, or to better identify the route from the parking space to the front door. Graphic objects such as a vehicle manufacturer's logo or other information can also be projected into the vehicle's surroundings.
[0006] Furthermore, DE 102019 135410 B4 discloses a motor vehicle with a projection device for detecting a user's input gesture with respect to a projection, as well as a method for operating a projection device. Using the projection device, virtual control elements can be projected onto projection surfaces in the vehicle's surroundings. The virtual control elements can be operated by user gestures.
[0007] Furthermore, US 2015 / 0180999 A1 discloses an automatic social network interaction system for a vehicle. The system is capable of identifying a user and logging into the user's profile on a social network. A user interface can be projected onto a window of the vehicle, and the user interface can be operated using gestures. The present invention is based on the object of providing an improved vehicle characterized by an enhanced user experience.
[0008] According to the invention, this object is achieved by a vehicle having the features of claim 1. Advantageous embodiments and further developments emerge from the dependent claims.
[0009] A generic vehicle, comprising a plurality of configurable components, detection means, context determination means and a computing unit which stores a user profile database in which user profiles can be stored, wherein a respective user profile is formed at least by a compilation of configuration parameters of the configurable components, wherein at least two user profiles are stored for at least one user in the user profile database, and wherein the computing unit is configured to detect, i.e. identify, persons present in the vehicle environment by processing sensor data generated by the detection means and to select user profiles contained in the user profile database for a person identified as a user, is further developed according to the invention in that the computing unit is further configured to:
[0010] - to control projection means of the vehicle for outputting a light pattern into the vehicle environment, wherein the light pattern contains a visualization of the user profiles and the respective user profile probability at least for at least the identified user;
[0011] - by processing the sensor data, to recognise a selection gesture made by the person identified as the user on a visualisation contained in the light pattern, to interpret the selection gesture as the input of an operating action and to activate, change and / or change a context-specific user profile underlying the selected visualisation and / or to change a configuration parameter underlying the selected visualisation;
[0012] - to determine a situational context, taking into account context data generated by context determination tools, and to select context-specific user profiles suitable for the situational context; and
[0013] - to determine a user profile probability by processing the context data, which describes the degree of probability that the respective context-specific user profile fits the current situational context for at least two context-specific user profiles of the identified user. In other words, the vehicle has a projection device which can also function as a user interface. This enables the user to conveniently make selections and settings relating to respective user profiles even outside the vehicle. For this purpose, the selection gesture can be recognised with the aid of the detection means. For example, the user's movements can be recognised and tracked with the aid of cameras, whereby pointing at or crossing a respective visualisation or graphic object can be recognised. A corresponding selection gesture can also be made by determining the relative position or
[0014] Detect a user's position change relative to the vehicle using radar sensors, ultrasonic sensors, and a lidar. The vehicle according to the invention allows for particularly convenient user interaction.
[0015] The vehicle can be equipped with, for example, cameras, microphones, weight sensors, laser scanners, ultrasonic sensors, radar systems, transponders, and the like as detection devices. Cameras can be used to visually record and evaluate the vehicle's surroundings, whereby biometric characteristics of people, such as characteristic facial features, can be recognized using machine vision methods in order to uniquely identify individuals. The sensor data generated by the detection devices also includes movements of a person, preferably identified as a user, which can possibly be interpreted by the computing unit as a selection gesture. In this case, the sensor data forms the database from which the computing unit determines not only the user's identity but also recognizes the user's movements or gestures.Using lidar, radar systems, or ultrasonic sensors, depth information can be obtained, allowing the detection of a person approaching the vehicle and their movements. This also makes it possible to detect the passing of a person or animal, as well as the approaching of the vehicle, and to project the light pattern only when an identified user actually approaches the vehicle. By evaluating depth information, a person's characteristic gait pattern can also be detected, which also makes it possible to identify individuals.
[0016] The vehicle can be equipped with various lighting devices as projection devices. For example, high-resolution matrix headlights or specially designed projectors are possible. Such a projector can contain LEDs or lasers as a light source. Such projectors can be integrated anywhere in the vehicle, for example in a door sill, exterior mirror, bumper, and the like. The light pattern can thus be projected anywhere in the vehicle's surroundings. Projection is possible onto horizontal, inclined, and vertical surfaces. This ensures reliable recognition for the user in different situations. To deflect light beams, such a projector can also be equipped with various actuators such as movable mirrors, reflectors, lenses, and the like. The projector can have other components such as filters, lenses, diffusers, apertures, and the like.
[0017] Microphones can be used to analyze people's voices and also issue voice commands. This allows the light pattern to be projected into the vehicle's surroundings either automatically when an identified person is detected approaching the vehicle, or only after the user has issued a corresponding voice command.
[0018] The methods described above enable particularly convenient user identification. This eliminates the need for the user to carry an identification feature such as a radio key, a transponder, or a mobile device with a digital key function. Of course, as already mentioned, the vehicle can also be equipped with a corresponding transceiver device that can detect such identification features and thus enable or validate user identification.
[0019] In one embodiment according to the invention, the computing unit selects context-specific user profiles suitable for the respective situation, taking into account context data generated by context determination means. Depending on the external boundary conditions, several context-specific user profiles may be possible, from which the user actually wishes to select one. The preselection made by the computing unit does not necessarily have to correspond to the user's wishes. By projecting the light pattern into the vehicle's surroundings, the user receives information as they approach the vehicle as to which context-specific user profiles the vehicle is suggesting for selection and which user profile is preset, i.e. which is set in the absence of an operator action.
[0020] The vehicle uses various sensors, control units, and the computing unit to determine the context. For example, the vehicle may have temperature and humidity sensors that allow the computing unit to evaluate the current climatic and weather conditions. If it is warm, for example, the computing unit can suggest a context-specific user profile that sets the vehicle's air conditioning system to high ventilation speed, with a temperature selection of 20°C, and with the air conditioning activated. For a convertible, opening the convertible top could also be included in the corresponding user profile as a configuration. However, if it is cold and possibly raining, the computing unit selects a context-specific user profile that sets the convertible top to closed or the ventilation system to warm.Information for deriving the context data can also be obtained externally. For this purpose, the computing unit can be connected to corresponding control units via which the information is received. For example, the computing unit can query climate or weather data from a weather service or traffic reports from a traffic service. A respective user can also have a (digital) calendar. The calendar can be carried in the vehicle, be accessible on a mobile device such as a smartphone to which the computing unit has access, or be accessible via the Internet. For example, the computing unit can be connected to the Internet via a telecommunications unit via a mobile network and thus access the calendar. The user's appointments can be stored in the calendar, which can be taken into account by the computing unit to derive the context data.For example, if a doctor's appointment is scheduled for the morning, the computing unit will deduce that the next trip is not a commute to work and will accordingly suggest a context-specific user profile in which music is played via the vehicle's infotainment system instead of news. Other factors influencing the context include the date, the day of the week, the time of day, the number of vehicle occupants, the mood of a vehicle user, the vehicle's load, day or night, brightness, visibility conditions such as fog or a low sun, the route of a navigation route set via the vehicle's navigation system, and the like.
[0021] According to the invention, the computing unit is further configured to process the context data to determine a user profile probability, which, for at least two context-specific user profiles of the identified user, describes the degree of probability that the respective context-specific user profile fits the current situational context. For example, two or three of the user profiles with the highest user profile probability are then output for an identified user using the projection means. Since the user receives this information outside the vehicle, they already know which user profile has been selected or which user profiles are available for selection upon entering the vehicle. Cumbersome operation in the vehicle to obtain this information is then no longer necessary.
[0022] Various procedures can be programmed into the computing unit to determine the user profile probability. For example, the computing unit can perform a weighting depending on the individual context data. For example, an object detection can be compared with the current time, the location of the vehicle, and a brightness sensor value. This way, the vehicle can recognize, for example, that the user is wearing a leisure suit instead of an office outfit, even though it is a weekday and the usual time for commuting to work. Furthermore, it is already light. The vehicle is at the user's place of residence. The location of the vehicle and the image recognition can have a greater weight than the brightness sensor value and the time, resulting in a high user profile probability for a "leisure profile" and a low user profile probability for a "work profile."In this case, it could of course be the case that the user still wants to go to work and is wearing a leisure suit today, for example, because there are no meetings scheduled. In this case, they will prefer the work profile to the leisure profile, even though the latter has a lower user profile probability.
[0023] The light pattern also contains an output of the user profile probability. This informs the user whether the computing unit considers multiple user profiles suitable for the current situation. For example, if two context-specific user profiles are displayed that have a similar user profile probability, even though it is clear to the user that one of the two user profiles should be clearly preferred in the current context, the user can make appropriate settings that shift the user profile probability toward the preferred user profile. If the current context then occurs again, the computing unit will more reliably suggest or preset the context-specific user profile actually preferred by the user. This counteracts the automatic activation of a context-specific user profile not preferred by the user.
[0024] The basic content of the light pattern can be designed in different ways. For example, the light pattern can contain text, numbers, and / or geometric objects. For example, two context-specific user profiles can be projected into the environment along with their names. The user profile probability can be projected next to each of them in the light pattern as a percentage.
[0025] An advantageous embodiment of the vehicle according to the invention provides that the computing unit is further configured to control the projection means such that, in order to visualize a respective, preferably context-specific user profile in the light pattern, an individual graphic object is included in the light pattern for each user profile to be projected into the vehicle environment, wherein the surface area of the individual graphic objects is selected depending on a respective user profile probability. This ensures particularly intuitive and rapid comprehension of the light pattern content by the user. For example, the light pattern can contain a circle for each user profile to be displayed. The individual circles then have a different diameter and thus surface area. The higher the user profile probability of the respective user profile, the larger the surface area.Different user profiles can also contain different graphic objects. For example, if four user profiles are to be displayed, a first user profile could be represented by a circle, a second user profile by a triangle, a third user profile by a square, and a fourth user profile by a star. Additional information, such as a profile name, can be displayed as text within or next to the respective graphic object. The user profile probability can also be displayed as a number, for example, 75%, 12%, 7%, and 6%.
[0026] The user profile with the highest probability can also be placed geographically closest to the location of the identified user, while the user profiles with the lower probability are placed further away. For example, the most likely user profile is placed in front of the driver's door of the vehicle, and the remaining user profiles are displayed in the trunk area.
[0027] According to a further advantageous embodiment of the vehicle, the computing unit is further configured to control the projection means such that individual graphic objects or the light patterns are designed differently in terms of their color, contrast, sharpness, color gradient, brightness, transparency, animation, supplementary text information, and / or supplementary pictograms. This further facilitates the quick and clear differentiation of the respective user profiles for the user. The different visual representations of the graphic objects can be implemented depending on the user profile probability, on the configuration parameters contained in the respective user profiles, or can also be freely configured by the user.For example, if there is a high user profile probability, the respective graphic object can be displayed in a particularly bright color, with high contrast, high sharpness, high brightness, low transparency and the like, and correspondingly, if the user profile probability is low, in a pastel color, with low contrast and / or low sharpness, low brightness, high transparency and the like.
[0028] Animated pictograms can also be included in the individual graphic objects, facilitating even faster user comprehension. For example, a work profile could include a walking stick figure with a briefcase in hand, and a leisure profile could include a smiley face. A rainy profile could include a cloud with falling raindrops, and a sunshine profile could include a shining sun.
[0029] Preferably, the computing unit is further configured to read and analyze the settings of the respective context-specific user profiles, i.e., the configuration parameters themselves, and to adapt the visual design of the graphic objects to be projected accordingly. For example, if a work profile and a leisure profile are to be included in the light pattern, both profiles could be represented by a circle, with the work profile being particularly sharp and displayed in white and black, and the leisure profile by a colorful gradient moving from left to right through the graphic object, with the corresponding circle itself wobbling back and forth on the floor, creating a vibrating appearance.This correlates, for example, with playing heavy metal music in the vehicle while driving as opposed to the news, as well as with colorful interior lighting that is dependent on the music as opposed to static, cool white ambient lighting. Thus, the configuration parameters stored in the respective user profiles become apparent to the user simply by looking at the graphic objects, allowing for an even faster comprehension and even more reliable understanding of the visualizations contained within.
[0030] According to a further advantageous embodiment of the vehicle according to the invention, the computing unit is further configured to control the projection means such that at least one visualization of a configuration stored in a user profile also contained in the light pattern, with corresponding configuration parameters, is included in the light pattern. This enables even easier interpretation by the user of the settings assigned to the respective user profiles, i.e., characteristics of the configuration parameters. The additional visualizations of the configuration parameters of the respective user profiles can be displayed for all, a selection of, or just for an individual user profile contained in the light pattern. Preferably, configuration parameters that are particularly relevant for the respective user profile are displayed. In particular, this only occurs for the most likely user profile.
[0031] For example, the light pattern can contain two preferably context-specific user profiles, namely a sunshine profile and a rain profile. The user profile probability is higher for the sunshine profile than for the rain profile. For example, both user profiles are symbolized by a circle as a graphic object, with three additional circles displayed relatively close to the circle symbolizing the sunshine profile in the light pattern. The first additional circle shows the pictogram of a convertible with the top open. The second additional circle shows a temperature of 22°C as a number. The third additional circle shows a fan with the number 2.This allows the user to quickly and intuitively understand that the processing unit will automatically set the sun user profile, which will open the convertible top and configure the ventilation system according to the settings shown in the second and third additional circuits. Additional circuits for the rain profile could also be included in the light pattern.
[0032] Preferably, the computing unit is further configured to select, depending on the context data, the at least one configuration to be included in the light pattern with the corresponding configuration parameter. Routines can thus be implemented in the computing unit that determine which configuration parameters are characteristic of a respective context-specific user profile. Since the sunshine profile and the rain profile differ primarily in the setting of the convertible top and the climate control system, the computing unit displays this information in addition. For the work profile and the leisure profile, however, information relating to the vehicle's infotainment system and / or the ambient lighting could be displayed.
[0033] The user can also make additional settings via a submenu in the vehicle's infotainment system if they wish to display specific configuration parameter settings for a specific context-specific user profile. This allows the user to configure the design routines for the light pattern themselves.
[0034] If the user wishes to select a specific context-specific user profile, they can, for example, confirm that this user profile should be activated by selecting the visualization symbolizing the user profile with the highest user profile probability, or activate a different user profile by selecting a visualization symbolizing a user profile with a lower user profile probability. If the user's preferred context-specific user profile is not symbolized by a visualization in the light pattern, the light pattern can generally also contain a visualization for opening a submenu listing all context-specific user profiles. The user can then select their preferred user profile from this list.
[0035] In addition, the user can manipulate individual configuration parameters in the additional display. For example, if they want to activate the sunshine profile while using a closed top, they can make a corresponding input to the first additional circuit, which closes the convertible's top. This would also allow them to change the temperature setting for the air conditioning system. For example, the second additional circuit could display an upward-pointing arrow above the temperature display and a downward-pointing arrow below the temperature display. By selecting the appropriate arrows, the temperature can then be increased or decreased incrementally by, for example, one degree Celsius.
[0036] Preferably, the computing unit is further configured to recognize a person crossing and / or touching a visualization with a foot as a selection gesture. This enables particularly convenient operation for the user. The user simply needs to lift their leg to tap the corresponding visualization, for example, a respective individual graphic object, with their foot. A selection can be detected, for example, by the foot coming to a standstill or reversing its direction of movement.
[0037] According to a further advantageous embodiment of the vehicle, the computing unit is further configured to control the projection means such that, after selecting a visualization, further information relating to the respective user profile underlying the visualization or the configuration parameters underlying the visualization is displayed in the light pattern. In other words, the visualizations of the light pattern, for example, the individual graphic objects, can be clickable. Clicking on a corresponding visualization then opens a pop-up submenu. In such a pop-up submenu, further settings can be made or additional information can be displayed to the user.For example, three user profiles could be symbolized by individual graphic objects in the light pattern. Selecting one of the graphic objects would display additional visualizations in the light pattern, showing the respective configuration parameter settings for relevant or all configuration parameters of the selected user profile. Selecting or clicking on that user profile again would then activate it.
[0038] A further advantageous embodiment of the vehicle further provides that the computing unit is configured to recognize a characteristic operating sequence or a characteristic operating pattern in an operating action and thereby receive user authorization. This can be compared to entering a PIN, password or unlock pattern, as is known, for example, from smartphones. The light pattern may or may not have a corresponding input surface for entering the characteristic operating pattern. In particular, if no such visual information is contained in the light pattern, it is made more difficult for an attacker to enter operating actions via the light pattern. In this case, for example, the light pattern could be projected into the vehicle's surroundings, but no operating actions could be entered. Only when the characteristic operating sequence orIf the characteristic operating pattern is recognized, the light pattern is enabled to receive actual operating actions. However, if corresponding input fields are displayed, such as a numpad or a tile field, it is easier for the user to determine whether they are performing the characteristic operating pattern correctly.
[0039] The recognition of the characteristic operating sequence or characteristic operating pattern and the corresponding receipt of user authorization can be used by the computing unit to grant the user additional usage rights. For example, more in-depth access to vehicle functions can be granted. According to a further advantageous embodiment of the vehicle, the computing unit is further configured, after receiving user authorization, to enable the selection of a user profile, unlock the vehicle doors, and / or authorize a drive motor for use. This allows for even more convenient use of the vehicle, as the user can thus enter or start the vehicle without carrying a vehicle key. Authorizing the drive motor can be compared to starting a starter, releasing an immobilizer, activating the ignition, or, in an electric vehicle, even waking up on-board electronics.
[0040] After receiving user authorization, i.e., immediately after entering the characteristic operating sequence or pattern, the drive motor can be enabled immediately, or a vehicle control device can be enabled to receive a start command. For example, vehicles may have a start button instead of an ignition lock, which can be used to start the vehicle's engine. This start button can then be enabled. However, if the drive motor is enabled immediately after entering the characteristic operating sequence or pattern, a particularly convenient and quick drive off is possible for the user. Accordingly, the drive motor is started before even entering the vehicle.
[0041] Preferably, the computing unit is further configured to process the sensor data to create a new user profile for a vehicle occupant detected for the first time and to assign this new profile to that vehicle occupant. This further increases user convenience, as the effort required to store user profiles is reduced.
[0042] Further advantageous embodiments of the vehicle according to the invention also emerge from the exemplary embodiments which are described in more detail below with reference to the figures.
[0043] Showing:
[0044] Fig. 1 is a schematic plan view of a vehicle according to the invention;
[0045] Fig. 2 is a detailed view of a light pattern projected into the environment by the vehicle according to the invention;
[0046] Fig. 3 shows a representation of a light pattern projected into the environment at two consecutive times before and after a user interaction; Fig. 4 shows a further detailed view of a light pattern projected into the environment, showing an unlocking pattern; and
[0047] Fig. 5 is a flowchart of method steps carried out by a computing unit of the vehicle according to the invention for projecting the light pattern into the environment.
[0048] A vehicle 1 according to the invention, shown in Figure 1, comprises detection means 2, context determination means 3, and a computing unit 4. The vehicle 1 further comprises a plurality of configurable components (not shown in detail). For example, the vehicle seats can be adjusted to the stature of a respective vehicle occupant, playback parameters of audio and video content can be adjusted via the infotainment system of the vehicle 1, seat heating can be activated, a ventilation system can be adjusted, and the like. Each vehicle occupant has their own preferences as to how the corresponding components should ideally be configured. The computing unit 4 further comprises a user profile database in which a respective user can create multiple user profiles, wherein for an activated user profile, the corresponding components of the vehicle 1 are configured as defined by the respective configuration parameters stored in a user profile.
[0049] For one and the same user, several user profiles can be defined and saved, which are activated in a context-specific manner, i.e. depending on the situation. For this purpose, the vehicle 1 comprises said context determination means 3. This is the computing unit 4 itself as well as components of vehicle subsystems such as temperature sensors 11, control units 12, a telecommunications unit 13 and the like. With the help of the context determination means 3, the vehicle 1 is able to determine a situational context, for example what time it is, what day of the week it is, what date it is, what weather conditions exist, what route is planned for the next trip with the vehicle 1, what the traffic conditions are along the route, what appointments the vehicle user has next, and the like.The computing unit 4 is able to select a respective context-specific user profile for activation depending on the determined situation context.
[0050] With the help of the detection means 2, for example in the form of radar sensors, a lidar, external cameras, an ultrasonic sensor system and the like, static and dynamic environmental objects can be detected. This allows the computing unit 4 to detect the approach of persons to the vehicle 1. Furthermore, persons can be clearly identified, for example by performing a gait analysis, scanning biometric features and / or reading a unique identification feature such as a digital vehicle key. Furthermore, the detection means are configured to recognize operating actions performed by a user as gestures. The selection gestures can be a pointing gesture, a gaze gesture or any other movement in space, which are recognized by the detection means using methods also known from the state of the art.
[0051] The vehicle 1 further comprises at least one projection device 5. This can be, for example, high-resolution matrix headlights or LED or laser projectors. Projection devices 5 can be arranged anywhere on the vehicle 1, for example, in the front of the vehicle, in the radiator grille, in the exterior mirrors, in a skirting board, integrated into a bumper, and the like.
[0052] If the computing unit 4 identifies a user approaching the vehicle 1, a light pattern 6 can be projected into the vehicle's surroundings using the projection means 5. The light pattern 6 contains information about the context-specific user profiles selectable by the user. Thus, the light pattern 6 contains a visualization 7 for at least two user profiles of the identified user. For each displayed user profile, a user profile probability is displayed, which describes the probability with which the respective user profile was determined by the computing unit 4 to be appropriate for the current situational context.
[0053] Thus, there is a general risk that the computing unit 4 predetermines such a user profile that the user does not want to activate. However, due to the light pattern 6 projected into the surroundings, the user is able to estimate, as they approach the vehicle 1, whether the computing unit 4 has actually selected the preferred user profile and, if necessary, select a different user profile.
[0054] Figure 1 illustrates, using a first example, what the light pattern 6 can look like. According to the invention, a respective user profile is symbolized by an individual graphic object 8. These are, for example, geometric figures such as circles, rectangles, squares, triangles, stars, or any other polygonal figures. The individual graphic objects 8 are preferably displayed according to the user profile probability. A user profile that is particularly likely to match is displayed accordingly large, and a user profile that is less likely is displayed small. The corresponding visualization 7 is therefore composed of an individual graphic object 8 whose size is scaled to match the user profile probability. Additionally or alternatively, instead of a size difference, the user profile probability could also be included in the light pattern 6 as plain text, for example as a percentage (not shown).
[0055] The graphic objects 8 can be arranged arbitrarily in the light pattern 6. For example, the graphic object 8 representing the most probable user profile is displayed separately, and the other graphic objects 8 are aligned to one another in the manner of a list.
[0056] Figure 2 shows another possible example of an implementation of such a light pattern 6. In addition to the individual graphic objects 8 for each user profile, the light pattern 6 contains visualizations 7 in the form of supplementary objects 14.1 for the user profile most likely to match the current situational context. These supplementary objects symbolize information describing a respective configuration parameter of the corresponding user profile. For individual supplementary objects 14.1, additional sub-supplementary objects 14.2 can also be displayed.
[0057] In the example shown in Figure 2, graphic object 8, which symbolizes the user profile with the highest user profile probability, is a work profile that contains settings for vehicle components that the user prefers while driving to work. For better understanding, a worker is depicted as pictogram 15 in graphic object 8. The supplementary objects 14.1 show a convertible with a closed top and, as an audio source, a radio for playing acoustic media content via the infotainment system of vehicle 1.
[0058] Operating actions can be entered via the light pattern 6. This is explained in more detail below in connection with Figure 3. Corresponding visualizations 7 can contain selection areas such as arrows pointing up and down. By issuing a selection gesture on such an arrow, the audio source can be changed, for example, and music can be played via the vehicle radio, smartphone, an SD card, or the like, and the sub-supplementary object 14.2 can be used to set which station should be tuned into the radio. This enables a user to optimally adjust the vehicle 1 before even entering the vehicle 1. Instead of arrows, a respective graphic object 8, supplementary object 14.1, and / or sub-supplementary object 14.2 can itself function as a selection or control area. The graphic objects 8, which are shown smaller in comparison, symbolize the less likely to match the context-specific user profiles.In addition to a pictogram 15, the determined user profile probability and a descriptive keyword can be displayed in plain text (not shown). In the "Audiobook" profile, for example, the user's smartphone is set as the audio source and an audiobook app is automatically activated. In the "Racing" user profile, however, a firm suspension setting is selected and a sporty automatic gear selection is activated, so that gear shifts only occur at higher engine speeds.
[0059] In addition, a menu object 14.3 can be included in the light pattern 6. By performing a selection gesture on the menu object 14.3, for example, a pop-up submenu can be opened, via which the user can select all user profiles defined for him.
[0060] Selection gestures can be detected in various ways. With the help of the detection means 2, the relative position or change in position between people and vehicle 1 can be analyzed, allowing movements, in particular the approach of a person to vehicle 1, to be detected. This also makes it possible to identify which areas of the light pattern 6 a corresponding user is pointing at.
[0061] Particularly preferably, the person touching or crossing the visualizations 7 with a foot 9 is recognized as a selection gesture. For this purpose, the light pattern 6 can be monitored, for example, with the help of cameras, making it particularly easy to detect touching or covering the image content with a foot 9. If a corresponding graphic object 8 is crossed, as shown in the left part of Figure 3, a submenu opens, informing the user about the configuration parameters stored in the respective user profile. It would be possible for selecting information displayed in the submenu to directly change the corresponding configuration parameter.
[0062] Figure 4 shows an input mask 16. The input mask 16 can be, for example, a numpad, or, as shown, an array of circles or a tile field, or any shape or graphic. Characteristic operating patterns 10, here in the form of a touch sequence of the circles of the input mask 16, can be entered via the input mask 16. This allows user authentication to be performed, which allows the user to be granted additional access rights.
[0063] For example, vehicle 1 can be unlocked and / or the drive motor can be enabled, i.e., the engine can be started. The computing unit 4 executes the process steps shown in Figure 5 to project the light pattern 6 into the vehicle's surroundings. The process starts in process step 501.
[0064] In method step 502, the computing unit 4 retrieves sensor data provided by the detection means 2.
[0065] In method step 503, the computing unit 4 detects static and dynamic objects present in the vehicle environment.
[0066] In method step 504, the sensor data and context data generated by context determination means 3 are evaluated, whereupon the computing unit 4 determines the situational context. Corresponding information is forwarded as indicated by a dashed arrow.
[0067] In method step 505, computing unit 4 checks whether a person detected in the vehicle's surroundings can be identified as a known user. If this is not the case, the method ends in method step 514.
[0068] If, however, a known user is identified, the computing unit 4 checks in method step 506 whether the user is moving toward the vehicle 1. If this is not the case, the method also ends in method step 514. If this is the case, however, the computing unit 4 checks in method step 507 whether several context-specific user profiles are stored for the user.
[0069] If this is the case, the computing unit 4 determines the corresponding applicable user profile probability in method step 509. To do this, the computing unit 4 first checks in method step 508 which user profiles are even suitable for the respective situational context. For this purpose, for example, a separate linkage database that links different boundary conditions with the context-specific user profiles can be accessed. Corresponding information is also forwarded here, as indicated by a dashed arrow. If no user profiles are stored and no general setting suggestions are to be made, the method ends in method step 514. In method step 510, a suitable light pattern 6 is projected into the environment. In method step 513, suitable supplementary information, such as the aforementioned supplementary objects 14.1, sub-supplementary objects 14.2 and / or menu objects 14.3 are included in the light pattern 6.
[0070] In method step 511, the processing unit 4 checks whether a user touches or crosses an image content of the light pattern 6, i.e., a visualization 7, or otherwise selects it, which is considered an operating action. For example, entering the characteristic operating pattern 10 can also be detected.
[0071] If such an operating action is detected, the computing unit 4 carries out appropriate actions in method step 512 in order to activate the respective user profile or to change a corresponding configuration parameter.
