Description

The present embodiments are in the field of devices for a driver assistance system.

In motor vehicles, more and more driver assistance systems are used, which initially serve for navigation (for example route guidance or destination finding). Furthermore, in vehicles also so-called infotainment systems may be present, which can perform additional functions, such as playback of a radio station or the playback of entertainment media.

document DE 102013005342 A1 deals with a motor vehicle operating device. In a first embodiment, it comprises a head unit, augmented reality glasses, which has at least one display surface and which is operatively connected to the head unit. Furthermore, the motor vehicle operating device has a viewing direction sensor which is provided for detecting head movements and which is a position sensor arranged on the augmented reality glasses.

document EP 1990674 A1 is concerned with a display system having a sensor for acquiring environmental information, a processor for processing the environmental information, a display control unit which provides display information based on the environmental information for display to the user, and a user-portable display device for displaying the user display information.

document DE 102004057947 A1 deals with a procedure for checking the function of a driver assistance system integrated in the vehicle. The driver assistance system is operated as a function of at least one sensor signal given by a sensor which monitors the traffic situation in the vehicle environment. In this case, the driver is shown while driving a depending on one or more continuously detected, the vehicle movement descriptive vehicle parameters generated and continuously adjusted optical simulation representation of a virtual traffic situation in his direction to the vehicle environment field of view. The driver can still capture the real vehicle environment. The at least one sensor signal is simulated for the respective simulation representation as a function of the simulated traffic situation. In this case, the simulated sensor signal is transmitted to a control device controlling the operation of the driver assistance system, which optionally puts the driver assistance system into operation.

Further, in conventional devices, it may also be possible to retrieve vehicle or distance-related data, such as fuel consumption. For example, when navigating with the driver assistance system, a plurality of routes having different respective fuel consumption values may be possible. However, existing driver assistance systems provide little or no motivation for a driver to decide on the majority of possible routes for the route with the lowest possible fuel or energy consumption. In some cases, other route suggestions, e.g. because of less travel time or mileage, appear more attractive to a driver than the most economical route. Furthermore, an additional or improved motivation of a vehicle user could also be helpful, for example, to improve a driving behavior of the user in a currently occurring traffic situation.

There is therefore a need to improve a concept for motivation, information and support for a particular driving style for a vehicle user.

This need is taken into account by a device, a method and a computer program having the features of the independent patent claims. Further advantageous embodiments and further developments are the subject of the dependent claims.

According to a first aspect, embodiments relate to a device for a driver assistance system. The device can be coupled to a display surface and configured to generate an indication signal. The display signal causes a display of a virtual object in a field of view of a vehicle occupant. The virtual object appears stationary with respect to a vehicle environment for the vehicle occupant. Furthermore, the virtual object has information about a property of a route section. This may make it possible to direct the attention of a driver to a predetermined direction of travel, lane or route choice, thereby motivating the driver to avoid or continue driving on the same. Under certain circumstances, the driver may also receive an additional indication of traffic regulation in the case of route sections, or a consequence of a choice of route, direction or lane, such as, for example, increased expenditure of time or increased fuel or energy consumption, by virtue of the virtual object.

In some embodiments, the indication signal is changed depending on a current driving condition. This may possibly create opportunities for interactive execution. From a previous route choice of a Driver's resulting changes to another route planning can be taken into account.

In some embodiments, the device further comprises an input interface configured to receive data from a vehicle comprising the driver assistance system, another vehicle, or a database. A fleet knowledge of multiple vehicles over a predetermined route or another route with less expected fuel or energy consumption can be considered in this way.

In some embodiments, the device is further configured to generate the indication signal depending on the received data. Information from the fleet knowledge may possibly be communicated to the driver of the vehicle.

In some embodiments, the device is further configured to receive a drive signal indicating a position of a vehicle including the driver assistance system. The device is also designed to provide a feedback signal associated with the object to a vehicle occupant based on the drive signal when the virtual object is being bypassed by the vehicle. The driver can thus, if necessary, intuitively provide information, e.g. receive an economic aspect of his driving behavior or a chosen route choice.

In some embodiments, the device is further configured to receive a drive signal based on a position of a vehicle including the driver assistance system. The device is also designed to provide a feedback signal to the vehicle occupant assigned to the object based on the drive signal when the virtual object is passed through the vehicle. The driver may thus be able to provide more detailed information, e.g. receive an economic aspect of his driving behavior or a chosen route choice.

In some embodiments, the feedback signal includes a safety alert. Thus, an opportunity for the driver may possibly be increased to recognize a potential hazard as such and to act in a timely manner.

In some embodiments, the feedback signal includes a score. This may make it possible to provide an additional playful incentive for a particular, e.g. to create more economical, driving behavior for the driver.

In some embodiments, the apparatus further comprises a memory device configured to store the feedback signal. Thus, for example, previous can be compared with current scores, which may further increase an incentive for a more economical driving.

In some embodiments, the indication signal causes the virtual object to be displayed on a head-up display area. It could thereby create a possibility for integration of the display area in the vehicle.

In some embodiments, the indication signal causes the virtual object to be displayed on data glasses. Thus, multiple users could independently create a way of displaying the object

Some embodiments also relate to a motor vehicle. The motor vehicle includes a device and a device coupled to the head-up display area.

Some further embodiments also relate to a motor vehicle. The motor vehicle includes a device and an interface coupled to the device. The interface is adapted to transfer data between the device and data goggles. It could thereby provide a possibility for integration of a device comprising the device and the display surface into the vehicle.

According to another aspect, embodiments relate to a method for a driver assistance system. The method includes displaying a virtual object in a field of view of a vehicle occupant. The object appears stationary relative to a vehicle environment. The object also has information about a property of a route section. This may make it possible to provide motivation for a driver to continue on a predetermined lane or route or in a predetermined direction of travel. The object could also provide additional indications of traffic regulation or route information in the case of a route section to the driver.

In some embodiments, the method further comprises comparing a position of the vehicle with a position associated with the virtual object. In addition, the method includes taking a feedback action if the comparison satisfies a predetermined criterion. In this way, a possibility for an interactive integration of information can be created.

In addition, other embodiments also provide a program or computer program having program code for performing the following method when executing the program code on a computer, a processor or a programmable hardware component, such as an application specific integrated circuit (ASIC). The method includes receiving a signal characterizing a gesture of a user. The method also includes providing a control signal based on the signal that causes a characteristic of an audio signal emitted by a speaker assembly comprising at least one speaker in a vehicle.

1 shows an embodiment of a device 100 in a driver assistance system. The device 100 is on a display surface 110 coupled and adapted to a display signal 120 to create. The indication signal 120 causes a display of a virtual object 130 in a field of vision 140 a vehicle occupant 150 , The object 130 appears regarding a vehicle environment for the vehicle occupant 150 stationary. Furthermore, the object points 130 an information about a property of a travel route section.

The vehicle occupant 150 For example, it may be a driver of a vehicle that includes the driver assistance system, or a passenger or other passengers. In summary, the term "user" will be used for this in the following. The driver assistance system can be comprised, for example, by a motor vehicle. In other embodiments, the driver assistance system is also used for other locomotion scenarios, eg on foot or in a bicycle. Thus, a user may also be a pedestrian or cyclist.

A coupling can be wired or wireless (WiFi, Bluetooth, Miracast etc.) realized. The device 100 For example, it may be a processor, a computer, or a programmable hardware component. at 1 is the device 100 for example as a processor 100 shown. The display area 110 may be included, for example, by a device which is provided by the user 150 is portable on the head (head-mounted display, HMD). In one possible embodiment, this may be a data glasses. However, the display area may also be included by the vehicle. The display area 110 can transparent, and for example, a window of the vehicle with optical properties for displaying virtual content or a light field display include (Head-Up Display, HUD). A representation of the object 130 may be done using a visualization medium, for example, as a projection on the disc.

A fixed representation of the virtual object 130 means that the virtual object 130 essentially not moved in a direction parallel to the earth's surface. Accordingly, in addition to completely immovable objects, for example, a ball bouncing on a spot, a spinning top rotating about an axis or a gesticulating figure are considered to be stationary. The virtual object 130 In other words, it can also perform a repetitive motion (eg, oscillate, pulsate, spin, snap, hit).

The virtual object 130 is shown in perspective such that a position or an orientation of the object 130 related to the vehicle environment when changing a viewing direction of the user 150 preserved. The property of the travel route section may be, for example, a trafficability of the route section. This can also include, for example, expected fuel or energy consumption. The information about the driveability of the route section may include, for example, a recommendation to the driver of the vehicle, and for example, depending on a fuel or energy consumption or a currently engaged gear. The information about the trafficability can also include, for example, a request for a change of a lane or a route. Furthermore, additional information about a traffic rule may also be present in this case, eg maximum speed, minimum speed, overtaking ban, no-turn, restricted area or one-way street. In addition, information about current events, such as traffic jams or construction sites, may be included. The information may also include a safety alert, eg alerting to a hazard situation, such as an overtaking or oncoming vehicle. In other words, by the object 130 a situation-appropriate display of computer-generated data in the field of view of the user 150 be effected (augmented reality). An object 130 can act as a virtual destination, thus influencing the driving behavior of the driver. Furthermore, the virtual object 130 transparent, opaque (non-transparent) or displayed in one or more arbitrary colors.

Furthermore, an object can 130 also include a virtual obstacle or a waymark. In one embodiment, known information about a vehicle environment that may be provided, for example, by a sensor provided on the vehicle, in combination with a static map material or information (fleet knowledge) provided by a database, data server, or vehicle fleet may be used to determine a vehicle ideal route to be used. The fleet knowledge may in this case include information that is provided by another vehicle to the processor. The processor may include an optional receive interface for receiving data. "Fleet knowledge" may include current live data originating from vehicles in the environment or from a network, as well as data carriers or network-stored data obtained from past journeys.

In another embodiment, the object is 130 shown in stereo or three-dimensional. This allows the user 150 give an impression of a virtual object distance or depth. Optionally, in embodiments a motion tracking of the user 150 ( User tracking), for example, over the head, eyes or hands are made. This can be done via sensors included in the vehicle. Data about a movement of the user 150 , which are detected by the sensors, can lead to a correct adaptation of a representation of an object 130 be used. A time required for a data transmission or data processing, or in other words, a total latency of an embodiment can be so low that the virtual object 130 from the perspective of a driver or rider can plausibly insert into the environment. In other words, it allows swimming of the virtual objects 130 in the field of view 140 of the driver or passenger may be avoided.

In such embodiments, in which a display area (eg data glasses) itself is operated by a mobile computer system, data processing takes place at least partially directly on the data glasses. The processor 100 may therefore also be covered by the data glasses. The data processing can include, for example, a tracking or visualization.

Through the in 1 As shown, it may be possible to use an application for a user 150 to provide which may be designed interactively. For example, in an interactive embodiment, an object 130 be changed depending on a current driving condition of the vehicle. In other words, the application may be designed similar to a computer game, and thus possibly bring a playful motivation of a driver to a certain driving style. This may, for example, include a motivation for a more economical driving style. 2 shows a possible, playful embodiment of the application. In an interior of a vehicle 200 is a display surface located, which in the embodiment shown here of a data glasses 210 is included. In another embodiment, the display device and the windscreen 220 of the vehicle 200 include. In this case, for example, objects can be projected onto a windshield of the vehicle with the aid of a projector. In 2 Several objects are shown, which from the user's point of view 150 appear in its field of vision, and to be fixed in an environment of the vehicle. The objects shown here by way of example comprise a route marker 230 (For example, to highlight a lane marking 235 ), virtual landmarks 240 in the form of circles, spheres or points, as well as an arrow, which, for example, a request 250 to the driver 150 to a lane change there. The lane change request 250 can also be displayed firmly in the field of view without the driver being stationary in relation to the environment.

By showing the virtual landmarks 240 For example, a route to be traveled can be marked. As the user 150 the landmarks 240 (or other appearing objects) appear stationary, they behave like a real object from the user's perspective. Possibly. can change lane change requests 250 show when the vehicle 200 how to steer, for example, to initiate an overtaking process or to let pass an overtaking vehicle. The fixed representation of objects in the vehicle environment can allow driving through the object from the user's perspective. In other words, for the user 150 The impression arises to pass through the object or to run over as soon as the vehicle 200 passes the point of the vehicle environment where the object was previously displayed. When driving over or over an object, for example a virtual landmark 240 or a gate to be traveled, a feedback signal associated with the object may be sent to the user 150 to be provided. The feedback signal may include, for example, a score. In other words, in one embodiment, a driver earns when driving through the landmarks 240 Points accumulated in the course of a journey. The score can be, for example, in relation to an economical driving style. Thus, for example, a higher score may mean a more economical driving style. This may possibly motivate a driver to improve his driving style economically.

The feedback signal may further comprise a tactile or an audible signal. In another embodiment, for example, an audio signal may be played when the virtual object appears, one approaches the object, traverses the object, traverses, or bypasses. By means of such an acoustic underpainting, a higher entertainment value can be created with a playful motivation of the user for a specific driving style. Tactile signals can be generated eg by vibrations in the steering wheel or in the seat, for example when an object is being driven over. In addition, incorrectly traveled objects may be indicated by particularly strong vibrations or the like. In some embodiments, landmarks become 240 from the device that causes the visualization, for example, from the vehicle 200 , which includes the processor and the display area, or a data goggles, dynamically placed in the field of view of the user based on the current traffic situation. This allows a behavior of the landmarks adapted to a current situation 240 be effected. For example, the user may 150 when rear traffic comes, receive an instruction, one located on a left side lane landmark 240 no longer pass through. In other words, the display signal can be sent depending on the traffic situation. The landmark 240 For example, it may turn from a passable object to a non-passable object or obstacle, such as a barrier (wall, barrier, etc.) or a pawn (person, animal, etc.), or may change color, eg, green to red. In 2 For example, an existing ban on passing through a barrier 260 highlighted. For example, a color change may indicate that the user is 150 the landmark 240 to drive at a slower pace.

In further embodiments, several different types of landmarks may be used 240 being represented. These may be, for example, landmarks which are to be passed at increased speed, at reduced speed or in a predefined gear. landmarks 240 But they can also include virtual opponents (eg monsters, wild animals, fantasy creatures or combat machines) to a user 150 an indication of safe driving around or passing the landmark 240 in a predefined minimum distance. In other words, landmarks 240 content differences, and these differences can be dynamically adapted to a particular driving situation.

The one of a landmark 240 associated points, in some embodiments, are directed to a speed or fuel or energy efficiency (too high, correct, or too low gear) at which a landmark has been overrun. Furthermore, a feedback signal may also result as a result of a drive around an object to the user 150 to be provided. In other words, a landmark can be used 240 be presented as a virtual obstacle, and points awarded to a correct circumvention of this obstacle. In another embodiment, a landmark to be driven around can cause no or even negative points if the user nevertheless passes through them.

In further embodiments, a score may be compared with another score of another traffic participant, for example, using a data network. Such a data network may include, for example, an internet platform or social media. A calculation of a score can be done on a route-dependent basis. For example, a score may indicate a percentage level that relates to the maximum possible points of a current traveled route. Determining how many points can be achieved under which conditions can be used e.g. based on how many points other participants have earned so far on a traveled route. Thus, the entire scoring system can behave dynamically, and a level of difficulty, e.g. be adjusted to a median, an average, a minimum or a maximum score.

The calculations may e.g. take place on a central server or peer-to-peer between multiple vehicles. Furthermore, the processor may have an optional storage device. A score can thus be stored and retrieved at a later date.

In further embodiments, a feedback signal also includes a haptic or an acoustic signal. In addition, signals from other vehicles or also from databases can be received by the device, and based thereon a change of landmarks can be effected. For example, other vehicles can provide additional information about an actual traffic situation. Accordingly, a position or appearance of a landmark may change. In still other embodiments, in traffic situations requiring increased driver attention (eg, city traffic or slow-moving traffic) or above a certain minimum traffic density, a change or even a complete suppression of objects may be effected. By landmarks, for example, the driver can be given a recommendation for a fuel- or energy-saving driving. Furthermore, the driver can also be given a recommendation for holding a particular lane or for selecting a specific route. In another embodiment, it may be possible to mark landmarks, for example by gesture control. The marking can be carried out by a driver or by another vehicle occupant. In this case, an aiming or a targeting on a landmark by means of a pointing gesture or by facial expressions (eye control) of the driver or a rider can be made. Furthermore, marking of landmarks by several vehicle occupants can take place simultaneously. If, for example, the driver overlooks a landmark, it can be marked by a passenger.

Another embodiment may be implemented in a scenario of automated or automatic driving. In this case, a passenger in an autonomously driving vehicle can, for example, be shown virtual objects via, for example, data goggles, a head-up projection or another visualization system in the surroundings. The virtual objects can be from the Passenger can be selected by a predefined gesture. In response to this, the vehicle can automatically drive to this point, also taking into account a current driving situation, drive through it and thus collect points. For the passenger, an incentive can be created to collect as many points as possible. If the passenger overlooks a virtual object, he may for example miss points.

3 shows a flowchart of a method 300 according to an embodiment for a driver assistance system. The procedure 300 includes an ad 330 a virtual object in a field of view of a vehicle occupant. The object appears stationary relative to a vehicle environment. The object also has information about a property of a route section. In some embodiments, the method includes 300 optionally a comparison 320 a position of the vehicle with a position associated with the virtual object. In addition, the process includes 300 optionally a grab 330 a feedback action if the comparison satisfies a predetermined criterion. In this way, a possibility for an interactive integration of information can be created. The criterion may be, for example, reaching a maximum distance from the object position. Also, such a criterion, for example, take into account a possible overtaking on a confusing stretch of road or in a multi-lane road backward traffic. A feedback action may be generating or storing a feedback signal, such as storing a score. Further, a feedback action may also include changing the object.

The procedure ( 300 ) can be performed, for example, by a program with a corresponding program code if the program code is executed on a computer, a processor or a programmable hardware component. In another embodiment, the programmable hardware component includes a chip for executing a fixed predefined program code (eg Field Programmable Gate Array (FPGA)).

Some embodiments, in addition to assisting in goal finding, goal achievement, or providing information on fuel or energy savings while in motion, may provide information from another vehicle, a database, a network (Car2X communication), or also To provide information to the user on sensors integrated into the vehicle (ACC / radar, parking sensors, ultrasound, camera, tilt sensors, etc.). Further, through some embodiments, the user may be motivated to drive more efficiently or fuel or energy. Any prior knowledge of the user to a fuel- or energy-saving driving style can be used explicitly, for example by optionally setting a different level of difficulty (good fuel savers can drive in a high degree of difficulty get less, smaller or other virtual aids or generate more points when driving through the help ), or completely omitted in another embodiment. The application can also be executed independently of navigation with the vehicle. Furthermore, it may also be possible to use embodiments in a piloted or automatic driving. In other words, this may be a situation in which the driver performs driving functions only in sections, but constantly monitors them. The driver or a passenger can specify a destination of a journey. Here, a route to the destination can be created dynamically, and adjusted based on known information. Through embodiments, if necessary, the motivation for a driver or passenger can be increased to observe the traffic and to intervene in critical situations in the driving situation. The motivation can also make driving maneuvers comprehensible to a user, which increases their confidence in information provided by a driver assistance system, and thus may possibly lead to increased driving comfort. Embodiments may also increase an entertainment value on a ride for the user, which may further enhance ride comfort. Some embodiments may also allow interference in a field of view of the user or hide, or to draw the attention of the user specifically to a detail of a vehicle environment.
