Description

The invention relates to a method, a device and a corresponding computer program for controlling a mobile user device of a driver of a vehicle, in particular in an at least partially automated driving. Furthermore, the scope of the invention also includes a suitably equipped mobile user device.

In the future, vehicles will be operated increasingly automated, so that a driver does not always have to concentrate on the vehicle or on the driving environment. However, depending on the situation, it may be necessary for the driver to focus on the driving environment (even at very short notice). At the same time it is the desire of the occupants of the automated moving vehicle to use the ever greater relief of the driving tasks for further employment.

It is an object of the present invention to provide a method and a device comprising a mobile user device, which provide improved usability of a mobile user device in the vehicle, in particular in an at least partially automated driving, in particular by the driver of the vehicle. Furthermore, it is the object of the invention to output a (expedient, desired or necessary) information to a driver of the vehicle, in particular in connection with an at least partially automated driving.

The object is solved by the features of the independent claims. Advantageous embodiments are characterized in the subclaims.

The invention is characterized by a method for controlling a mobile user device of a driver of a vehicle, in particular in an at least partially automated driving. The invention is also characterized by a device which is designed to carry out the method. The method includes determining a level of driver attention to a mobile user device and driving one or more output devices of the mobile user device depending on the level of attention at the mobile user device.

In particular, at least a degree of driver attention to a mobile user equipment may be determined cumulatively (such as with respect to all significant portions of the mobile user equipment). Preferably, the method comprises determining a degree of attention of the driver on at least one (specific) output unit of the mobile user device and driving an output unit, in particular the output unit and / or at least one further output unit of the mobile user device depending on the degree of attention of the driver at least one output unit of the mobile user device.

In other words, a cumulative attention of the driver to the use, in particular operation of the mobile user device and / or the attention of the driver to a particular output unit and / or input unit of the mobile user device can be determined and taken into account.

In this case, the triggering of a specific output unit or of a plurality of specific output units of the mobile user device can take place depending on the degree of attention to a specific output unit or depending on the distribution of the driver's attention to at least two output units of the mobile user device.

Preferably, the method is executable in an at least partially automated driving or as a function of the at least partially automated driving operation of the vehicle. The method is particularly preferably carried out by the driver of the vehicle ("at the wheel") depending on the use of the mobile user device. For the partially automated driving or the corresponding driving operation, a driving or driving operation supported by a driver assistance system can also be counted.

The mobile user device of the driver of a vehicle is, in particular, a mobile user device carried in the vehicle (when driving) or mounted in the vehicle. In particular, the driver's mobile user device is the mobile user device used by a (particular) driver.

In the method, the degree of attention can be determined, for example, depending on how the mobile user device is used, in particular operated. For example, if it is determined that the controls of the mobile user equipment (or associated controls), for example, be operated with a certain frequency, then increased attention to the mobile user equipment, in particular at an output unit and / or operating unit of the mobile user device can be assumed , The mobile user device of the driver can be stored, registered or automatically recognized as a mobile user device of the driver. It is particularly preferred to determine which part of the mobile user device is the driver's attention, for example, whether he is looking at a display device, whether he is listening to a speaker and / or holding it in his hand and / or if he has a specific input unit such as touch screen, testing, gesture operation, etc. served. For example, this can be determined with one or more sensors of the mobile user device. For example, the alignment of the user's view onto the display device of the mobile user device can be detected with the camera of the mobile user device oriented toward the user (in the case of the method, in particular towards the driver). In this case, the driver's gaze (towards the mobile user device or in a different direction, for example to the exterior of the vehicle) can be taken into account.

Listening to a (intense) listening of the driver to a content from a mobile user equipment or speaking to the driver may e.g. with the sensors of the mobile user device, e.g. on a touch-screen pattern, e.g. about ear print pattern and / or position or movement pattern of the mobile user device to be determined in space.

Determining the degree of attention of the driver can be detected by means of the mobile user device itself. Data from one or more sensors, for example the camera, the fingerprint sensor and / or operating elements, for example the keys or the touch screen of the mobile user device, can be evaluated. For example, it can be recognized that the driver inputs a text (on the touch screen of the mobile user device). A much higher level of attention can be assumed, comparable e.g. with (only) occasional control of a volume key of the mobile user device.

In this case, it can be determined that this requires a driver's attention which exceeds a certain extent and / or that it has a degree of operator activity exceeding a certain extent. In this case, a measure for the attention of the driver from an operating activity, in particular from the operating procedure (type, frequency, sequence of several operations) can be determined or estimated.

In particular, a driver's attention to a mobile user device exceeding a certain predetermined amount may also be determined and taken into account by means of the vehicle. Such a measure of attention may e.g. also be communicated to or with the mobile user device by a wireless data connection, wherein the mobile user device is then controlled in the manner described. For example, a measure of the attention at the mobile user equipment may be by means of at least one sensor of the vehicle, e.g. an interior camera can be determined. Further, attention may be drawn to a certain predetermined amount of attention at a mobile user equipment when it is determined that contact with and / or reaction of the driver with respect to one or more controls of the vehicle is less than a predetermined amount.

The attention or a measure of the said attention can in particular be estimated in the invention as an absolute measure, as a relative measure or as a distribution of the attention of the occupant, in particular of the driver. In this case, statistical data and / or data specific to the driver and so-called expert knowledge can also be taken into account.

Alternatively or additionally, in the method a comparison of several measures for driver attention may be carried out, wherein the at least two measures for the attention relate to a vehicle environment, to the interior of the vehicle and to the mobile user device, wherein at least one measure of attention with resources of the vehicle is determined and at least one measure of attention is determined by means of the mobile user device.

In particular, the method comprises checking whether the mobile user device is carried along with the vehicle. This can be done at the wireless connection or according to the invention at a correlation of the coordinates of the positioning system of the vehicle and the mobile user device.

• - Erfassung einer Verkehrssituation und/oder Ermitteln eines bestimmten Handlungsbedarfs des Fahrers des Fahrzeugs im Fahrbetrieb,
• - Ansteuerung der Ausgabeeinheit des mobilen Anwendergeräts abhängig von Verkehrssituation und/oder bestimmten Handlungsbedarfs.

According to an optional embodiment, the method additionally comprises:

• Detecting a traffic situation and / or determining a specific need for action of the driver of the vehicle while driving,
• - Control of the output unit of the mobile user device depending on the traffic situation and / or specific need for action.

The traffic situation and / or the need for action can be detected or determined by means of the mobile user device and / or by means of the vehicle.

It can thus additionally one of the detected traffic situation and / or of the at least one specific need for action of the driver Vehicle-dependent information to be provided to the mobile user device.

The information dependent on the detected traffic situation and / or on the at least one specific action requirement of the driver of the vehicle can be determined in the method, in particular by means of the vehicle or a vehicle unit, depending on one or more qualitative and / or quantitative parameters of the detected, especially interpreted traffic situation and / or the need for action.

For example, the output unit of the at least one mobile user device operated in the vehicle can be controlled in such a way that at least one content to be output so far, e.g. Display, image sequence, e.g. a movie, audio content is changed and / or paused. Thus, a (for modern people almost instinctive drive) the virtual content with a high attention to pursue, at least temporarily weakened.

The content to be output so far may be another, so to speak, "own" content, for example "own" content generated by the mobile user device, in particular independent of the vehicle or the journey. act a computer game or a user interface of a social network. The previously issued content is in particular independent of the vehicle or the ride in the vehicle. The output unit of the mobile user equipment may be more or less directly or indirectly, e.g. by influencing a running application or the operating system of the mobile user device. In particular, the control of the output unit can take place with a high (far above average) priority in comparison to at least one further content to be output.

Alternatively or additionally, the output unit of the at least one user device operated in the vehicle is actuated in such a way that by means of the output unit a passenger information (again interpretable by human perception) is output. In terms of their contents, output parameters, in particular an output time or output time interval, etc., the occupant information may be in a predetermined relationship with the detected traffic situation and / or with the determined need for action. For example, at least one content, output parameter, in particular an output time or output time interval is determined depending on one or more parameters of the detected traffic situation and / or the need for action. Preferably, the display of occupant information with a higher priority and / or perceptibility is initiated than one or more contents previously output at the mobile user device.

Preferably, the said occupant information can at least temporarily and / or at least partially replace at least one content that was previously output at the mobile user device. For example, by directly or indirectly driving the output unit of the mobile user equipment, a ratio of the sizes, display areas, contents of a content to be outputted (vehicle-independent) and a traffic situation and / or a need for action related to the operation the vehicle dependent) passenger information changed, in particular adapted.

In particular, the method is carried out such that, an occupant, for example the driver of the vehicle or an occupant in the driver's seat, occupant information regarding the traffic situation and / or a need for action, in particular with respect to an action to be performed by the occupant, by the said , in particular actively serviced by him, gets mobile user device. This can preferably be done in the method while the perception and / or attention of the occupant concerned is essentially concentrated on the mobile user device or certain other contents on the mobile user device, eg during its perception channels, eg eyes, targeted hearing, sensing, etc. the mobile user device is concentrated. Among other things, there is the advantage of a very fast transmission, a conscious perceptibility, readability of the occupant information or a corresponding, appropriate response by the occupant concerned. Thereupon, the respective inmate can then, in the real world, for example in relation to the current driving context of the drive, by the corresponding change of the contents output at the mobile user device to the mobile user device used by him and / or with the aid of the occupant information output at the mobile user device Real vehicle environment, etc., respond quickly or appropriately or act.
The transmission of said information to the detected traffic situation and / or the at least one specific need for action of the driver of the vehicle to the mobile user device of the driver of the vehicle can take place in the form of a predetermined code. In this case, the required data rate can be reduced, for example, in comparison to a transmission of all the information to be output at the mobile user device, or the transmission speed can be increased.

Particularly preferably, the transmission of said information takes place by means of an immediate wired or wireless data exchange. Preferably, the transmission of said information by means of WLAN or preferably by means of a so-called WPAN (= Wireless Personal Area Network), for example, a near-field transmission method, eg, Bluetooth or the like. In this case, a very high real-time capability of the method can be achieved. Thus, numerous advantages arise, for example, in comparison to an indirect data exchange, for example via a plurality of intermediate computing units. For example, the transmitted information may include control signals for direct or indirect control of the output unit of the mobile user device.

Furthermore, in the method, further (second) information can also be transmitted from the at least one mobile user device to the vehicle or to the vehicle unit. This further information may be indicative (among other things) of what activation of the output unit of the mobile user equipment has been successfully carried out, e.g. regarding the timing of the change of a previous content and / or the output of occupant information on the mobile user equipment. Also, further information may be indicative of the driver's reaction to the driving of said at least one output unit of the mobile user equipment.

For example, at least one function of the vehicle can be controlled to receive the wide information (depending on the receipt of the further information). For example, the at least one vehicle function, in particular a function for at least partially automated driving, will be controlled depending on whether and how the driver has reacted to the control of the output unit of his mobile user device. For example, further information can be transmitted from the at least one mobile user device to the vehicle or to the vehicle unit, which is indicative that the driver has interrupted the operation of the user device and / or the perception or attention of the mobile user device or of has turned away from a particular content of the mobile user device. Such further information can be determined, for example, by means of the mobile user device, e.g. by means of the camera of the mobile user device. The transmitted further information can be stored in the on-board network of the vehicle, e.g. be provided to control at least one vehicle function. Upon transmission of the further information from the at least one mobile user device to the vehicle or to the vehicle unit, e.g. an at least partially automated vehicle guidance, in particular a currently executed or planned for the near future vehicle guidance action, e.g. a maneuver, be changed, a decision with respect to at least one (current) influencing the leadership of the vehicle are taken or a safety measure, for example, a so-called pre-crash action in the vehicle be prompted.

The output unit here is in particular a display, e.g. a screen display and / or an actuator and / or an audio output and / or a unit connected to a body, such as a headphone and / or a hearing aid.

Particularly preferably, the control takes place in such a way that the control of the output unit represents a specific (concrete) information, in particular a concrete feature regarding the traffic situation and / or the specific (concrete) action requirement of the driver.

The method may preferably be executable in one or more mobile user devices carried in the interior of the vehicle. The method is particularly preferably implemented as a function of the recognition of at least one mobile user device and / or depending on a recognized (active) use of the at least one mobile user device in the vehicle and / or depending on the driving mode of the vehicle. The method may be executed depending on the recognition of a, in particular a degree exceeding, use of a mobile user device in the vehicle and / or recognizing the driving operation of the vehicle, in particular depending on a exceeding a certain limit parameter parameters of the driving operation of the vehicle.

The traffic situation in the context of this document is an up-to-date or, in the near future, a few seconds imminent traffic situation. In particular, the traffic situation is to be understood as a traffic situation in the immediate surroundings of the vehicle. In other words, the traffic situation means a traffic situation that is effective for the vehicle at the given time interval or in the near future of a few seconds (almost immediately). In particular, the traffic situation is a traffic situation recorded with sensory means (camera, radar, lidar, ultrasound system). Alternatively or additionally, the traffic situation may be understood as an arrangement or arrangement pattern and / or movement parameters of further objects, e.g. Road users in the immediate vicinity of the vehicle, e.g. in relation to the vehicle.

The traffic situation and / or the need for action in the procedure in connection with the respective driving context, type of road, urban, out of town, road layout, traffic sign arrangement, behavior of at least one other road users are recorded or evaluated.

Preferably, the evaluation of the traffic situation is carried out at least partially by means of the vehicle. In this case, the (suitably designed and / or configured) sensor system of the vehicle and in particular means of at least one driver assistance system, a safety system or a system for carrying out the at least partially automated driving can be used. Alternatively or additionally, evaluation of the traffic situation can be carried out at least partially by means of the mobile user device.

The method thus achieves that the driver, who is to do something in relation to driving and whose attention is predominantly in the virtual reality, prepares in the virtual reality for the (actual or future, predicted) real situation becomes.

In the method, a suitable occupant information, in particular at a suitably selected point in time, in particular depending on a predefined condition, can be output to the driver within the virtual reality perceived in a (predefined) relation to the traffic situation and / or a need for action , In particular, a need for action or action to be taken in relation to the identified traffic situation.

In a greatly simplified example, the driver gets selected occupant information regarding the current or imminent traffic situation or a need for action (tailored to this traffic situation), while still maintaining his or her perception, e.g. his view to a substantial extent still on the mobile user device or a content output at the mobile user device, e.g. in a virtual reality, is.

The said action requirement may be e.g. It may also be a necessary or recommended operation for operating the vehicle by the driver. Particularly preferably, the need for action or the occupant information which is output on detecting the action requirement relates to a specific driving task, for example influencing the transverse guidance, longitudinal guidance, maneuver execution of the vehicle. The occupant information can therefore be a specific information characterizing the traffic situation and / or the need for action, which information is directed in particular to the particular driver. Further, the occupant information may have a possible or imminent consequence of the traffic situation and / or performing or not performing an action, e.g. a specific operator action in relation to the vehicle or a driving task.

Furthermore, the occupant information output on the mobile user device depending on the transmitted information may relate to the actions, in particular driving tasks or driving actions, which are explicitly not recommended for the current time interval or in relation to the detected traffic situation and / or with regard to the determined action requirement. to avoid. For example, if it is determined that the occupant is actively using a mobile user device at the driver's seat and during which a certain driving action has been planned or started by the at least partially automated, in particular highly automated, moving vehicle, such an activation of the output unit can take place as a counterproductive (possibly instinctive or frightened) Reaction of the driver, eg braking is avoided. For example, when a change in the at least guidance of the vehicle, for example, an overtaking operation, threading operation, an avoidance operation (e.g., due to a changed traffic situation) is made partially automated, certain occupant information may be output at the driver's mobile user equipment. The occupant information may indicate that the driver should refrain from certain actions. In this case, the occupant information can also identify the specific reason and / or a consequence for the actions.

Alternatively or additionally, the said information to be transmitted to the mobile user device can be determined depending on a technical condition of the vehicle. For example, the information to be transmitted can be determined and transmitted as a function of a technical condition of the vehicle that falls below a certain limit value, in particular a technical condition of one or more vehicle systems requiring immediate or prompt action by the driver. Then, the at least one output unit of the mobile user device can be controlled accordingly. For example, the said information to be transmitted to the mobile user device can be determined as a function of a more or less abrupt or unexpected deterioration in the technical condition of the vehicle. For example, occupant information can be output on the mobile user device that contains a specific (applicable) technical problem of the vehicle and / or a specific need for action, if applicable, or within the current one Driving, in connection with the technical condition of the vehicle.

Thus, by the method also a longer orientation and orientation in the real situation after averting the perception and / or attention, e.g. the driver's gaze, the mobile user device, and / or the typically required eye accommodation (on a real) vehicle environment and / or vehicle displays.

An occupant information may be output to the driver of the vehicle who is already serving him or her before, during, or shortly after the transmission of his or her perception and / or attention from the mobile user equipment to the real environment of the vehicle.

Since the said transmission of perception and / or attention depends on numerous criteria, e.g. Lighting differences (between the interior of the vehicle, vehicle environment, display of the mobile user device), complexity of the driving context, disruptive factors can take up to 5 seconds, there is a significant advantage that the said, in particular certain occupant information during this time is already available or The driver is already known.

For example, occupant information may be output to the driver that provides the driver with at least one particular clue or tendency for a decision, reaction, driver's action, even before his or her perception and / or attention is sufficiently transmitted to the vehicle environment. In this case, the said time of a few seconds can be used appropriately and / or a surprise of the driver can be avoided, for example with a traffic situation not expected by him or by an action decision to be taken.

The information transmitted to the mobile user device (by the vehicle or by a vehicle-operated computing unit) can be determined in the method such that it is in a predetermined relationship with the traffic situation and / or the need for action.
The transmitted information can be determined depending on the particular, eg selected, eg one or more specific thresholds exceeding parameters of the traffic situation and / or a need for action. For example, it can be decided depending on one or more predetermined conditions that information is transmitted to or depending on the traffic situation and / or the need for action. Also, a content, a parameter of the information to be transmitted can be determined depending on one or more parameters of the traffic situation and / or a need for action.

• - Erkennen, dass die Aufmerksamkeit des Fahrers in Bezug auf eine Fahraufgabe und/oder Fahraktivität des Fahrers ein zweckmäßiges Maß unterschreitet, und
• - Ansteuerung der Ausgabeeinheit des mobilen Anwendergeräts abhängig von der erfassten Aufmerksamkeit des Fahrers in Bezug auf eine Fahraufgabe und/oder Fahraktivität des Fahrers.

According to another optional embodiment, the method also comprises:

• Recognizing that the driver's attention to a driving task and / or driving activity of the driver is below a reasonable level, and
• - Driving the output unit of the mobile user device depending on the detected attention of the driver with respect to a driving task and / or driving activity of the driver.

In this case, the driver's attention with respect to a driving task can be made by means known per se, for example by means of the detection of his head position, viewing direction, driver status recognition, in particular by means of the vehicle.

The driving activity of the driver is also a (sufficient, in particular to a sufficiently good driving style) perception of a (current or upcoming) driving task by the driver to understand.

The driving activity of the driver can be carried out by means of an evaluation of the actuation of the control elements of the vehicle, in particular for the longitudinal guidance and / or transverse guidance of the vehicle. For example, the driving activity of the driver can be determined depending on the haptic contact with a pedal of the vehicle and / or a handlebar of the vehicle.

Particularly preferably, the driver's driving activity can be determined, in particular estimated, depending on the degree of haptic contact on a relevant operating element. The degree of haptic contact can in turn be determined with a hands-on sensor, a hands-off sensor, by means of a pressure-sensitive mat in the steering wheel of the vehicle or with an interior camera of the vehicle.

Particularly preferably, the driving activity detected, in particular with means of the vehicle, is evaluated in relation to the current driving task or the current driving situation. In this case, the "expedient measure" can be determined as a quantity related to the driving context and / or driving situation and / or a current degree of automation.

• - Ermitteln eines Maßes der Aufmerksamkeit des Fahrers an seinem mobilen Anwendergerät, insbesondere, dass ein mobiles Anwendergerät des Fahrers bedient wird,

• - Entscheidung über die Ansteuerung der Ausgabeeinheit des mobilen Anwendergeräts.

According to another optional embodiment, the method comprises:

• - Determining a measure of the driver's attention at his mobile user equipment, in particular that a driver's mobile user equipment is being operated,
• Determining a measure of the driver's attention with respect to a driver's driving task and / or driving activity,
• - Determine a measure of the driver's attention with regard to further employment, in particular communication with a person, and thereupon:
• - Decision on the control of the output unit of the mobile user device.

At least two of three of the above-mentioned aspects of driver attention are particularly preferably determined and taken into account.

• - Erkennen eines vorliegenden Anwendungsfalls des mobilen Anwendergeräts, und/oder zumindest eines durch die Nutzung des mobilen Anwendergeräts beanspruchten Wahrnehmungskanals des Fahrers und daraufhin,
• - Ansteuerung der Ausgabeeinheit des mobilen Anwendergeräts abhängig von dem erkannten Anwendungsfall des mobilen Anwendergeräts und/oder des ermittelte beanspruchten Wahrnehmungskanals des Fahrers.

According to another optional embodiment, the method comprises:

• Detecting a present application case of the mobile user device, and / or at least one perception channel of the driver claimed by the use of the mobile user device, and then
• - Controlling the output unit of the mobile user device depending on the detected application of the mobile user device and / or the determined claimed perception channel of the driver.

If, for example, the mobile user device is held in the hand and thus telephoned, a first activation, for example a vibration and / or sound output, in particular comprising an announcement, can take place.

For example, if the mobile user device is being operated on the screen, e.g. played a game or viewed a map, a second control, such as a change and / or generating a display on the mobile user device can be done.

The use case of the mobile user device can be classified into two or more different classes. These classes may differ according to the driver's particularly stressed perception channels. These classes may also differ in the required, claimed or unclaimed perception and / or attention, gaze, listening, haptic contact, or haptic operation. In this case, the activation of the at least one output unit of the mobile user device can be varied depending on the detected application or the recognized class of the application.

According to a further optional refinement, the method comprises recognizing at least one specific perception channel of the driver claimed by the mobile user device, and in particular the intensity in which at least one perception channel is claimed, and then activating the output unit of the mobile user device depending on the detected perception channel , and in particular depending on the detected intensity. For example, the intensity in which a perceptual channel, in particular a particular perceptual channel of the driver is claimed, may be taken as an (at least coarse) measure, e.g. 2-8 levels are determined or estimated and appropriately taken into account.

For example, the stress (current usage, attention, sensory overload) on one or two driver perception channels may be detected in connection with the use of the mobile user equipment. Depending on the detected information, one or two actuations of the at least output unit of the mobile user device which concerns the at least two relevant perception channels of the driver.

Preferably, depending on the input and / or output of the mobile user device, in particular also of evaluated contents, it can be recognized which of the driver's perception channels currently perceives the contents of the mobile user device.

It can also be determined how intensively this perception channel is used or overloaded and then decided on the control of one or more actuators of the mobile user device. For example, a vibration and / or sound output, in particular comprising an announcement, or a change and / or generating a display on the mobile user device.

Furthermore, the possibility can be provided in the invention by means of the mobile user device to influence, in particular to operate, at least one, in particular a related function of the vehicle in connection with the method.

According to a further optional embodiment, a size representing a degree of automation of the vehicle is determined or predicted, and the control of the output unit of the mobile user device is performed depending on the determined size representing the degree of automation.

In this case, the information to be output by the mobile user device depending on the determined size representing the degree of automation, be selected differently and / or content may be different.

For example, other characteristics of the traffic situation can be reported with a low degree of automation than with a high degree of automation.

At a low degree of automation, for example, a relatively brief attention or operation of the mobile user device can lead to the control of the output unit. This can have no or a relatively low dependence on the driving situation and / or driving context.

With a high degree of automation, only relatively critical information, e.g. to traffic situations that are not sufficiently controlled by the vehicle issued. These can have no or a relatively low dependence on the deflection time and a relatively high dependence on the determined (automatically evaluated, interpreted) driving situation and / or driving context.

According to another optional embodiment, the control of the output unit of the mobile user device relates to a change of non-driving content.

The non-driving content is to be understood as unrelated or regarding the driving context and the traffic situation, e.g. not concerning a current driving context, traffic situation, driving task to be performed by the driver or by a system of the vehicle, but rather own contents of the mobile user device, e.g. concerning multimedia or (tele) communication, office work, a computer game, and the like.

For example, if a critical traffic situation is detected and / or a current or urgent need for action of the driver is determined, then a (distracting) control of the output unit of the mobile user device, especially those that has nothing to do with driving, explicitly pauses , issued in a weakened form and / or with a delay.

Alternatively or additionally, it can also be determined or explicitly recognized in the method that the driver does not operate the mobile user device and is taken into account in the method.

If, for example, it is determined that the driver's attention is essentially not or not yet on the mobile user device and that a traffic situation requiring driver attention is detected or predicted for the near future and / or a current or early driver action is determined, then the controls of the output unit of the mobile user device, in particular forward-looking and / or changed for a certain time interval, in particular at least partially suppressed, paused and / or output at a later time.

According to a further optional embodiment, depending on a transmitted information in connection with a detected traffic situation or with a need for action of the driver of the vehicle:

• a change of a currently output content, eg a current display of the mobile user device, eg a minimization of a (tendentially distracting) previously issued display, and / or a generation of a further display on the mobile user device in connection with the detected traffic situation or with the Need for action of the driver of the vehicle, and / or
• a change in an audio output of the mobile user device, eg a reduction of the volume or pausing of an auditory telecommunication, and / or an output of a sound in connection with the detected traffic situation or with the action requirement of the driver of the vehicle with the mobile user device, and / or

For example, the information to be transmitted to the at least one mobile user device operated in the vehicle and / or an occupant information output thereupon may include a parameter relating to the type and / or criticality of the detected traffic situation and / or to the type and / or urgency at least one (specific) need for action.

For example, the occupant information then output to the at least one mobile user device comprises a component (by human perception) that can be quickly interpreted, e.g. Symbols, selected sounds, certain haptic patterns, etc.

According to a further optional embodiment, the control of the output unit of the mobile user device is representative of:

• an invitation to attract driver attention to the vehicle environment,
• a request for the attention of the driver to an information of the vehicle, in particular to a display of the vehicle, in particular concerning a vehicle guidance,
• a request to grasp the steering wheel, in particular as a so-called "hands-on request"
• a request to tap or operate a pedal of the vehicle or a confirmation of operator readiness to operate at least one pedal by the driver,
• a request to change the vehicle speed,
• - a request to maintain a distance, in particular lateral,
• a request for the driver to participate in a particular maneuver,
• an invitation to the driver's decision in relation to a particular maneuver,
• a takeover request for at least part of the vehicle guidance by the driver.

In particular, a corresponding

Occupant information is outputted with the output unit of the mobile user equipment. This can e.g. be dependent on a parameter of the traffic situation and / or the need for action. For example, the occupant information may designate a feature of the request to apply the driver's attention to a (specific) object or space area in the vehicle or outside the vehicle, a feature of the action to be performed by the driver, etc.

According to a further optional embodiment, the triggering of the output unit of the mobile user device takes place as a function of one or more predetermined criteria with regard to the determined traffic situation and / or determining a specific need for action of the driver of an at least partially automated vehicle.

• - eine Einschätzung der Wichtigkeit und/oder der Eiligkeit einer Information zu einer erkannten Verkehrssituation und/oder eines Handlungsbedarfs des Fahrers,
• - eine Erkennung einer Verkehrssituation als eine Verkehrssituation einer bestimmten Art, z.B. eine Kollisionswahrscheinlichkeit,
• - ein Erkennen eines bestimmten Handlungsbedarfs hinsichtlich: Längsführung des Fahrzeugs und/oder Querführung des Fahrzeugs,
• - ein Überschreitung vorausbestimmter Schwellwerte. Auch können Schwellenwerte abhängig vom Fahrkontext (Stadtfahrt, Landstraßen Schnellstraße, Parken, Fahrer im dichten Verkehr, Nachtfahrt, etc.) gewählt werden.

For example, a predefined criterion may be considered:

• an assessment of the importance and / or the urgency of information on a detected traffic situation and / or a need for action of the driver,
• a recognition of a traffic situation as a traffic situation of a certain kind, eg a collision probability,
• a recognition of a specific need for action with regard to: longitudinal guidance of the vehicle and / or transverse guidance of the vehicle,
• - Exceeding predefined thresholds. Threshold values can also be selected depending on the driving context (city driving, highway expressway, parking, drivers in heavy traffic, night driving, etc.).

In a simplified case, the recognition of the at least one predetermined criterion can be a simplified identifier for the detected, evaluated or predicted for the near future traffic situation and / or possible or probable consequences of the traffic situation or an unfulfilled need for action of the driver, in particular the driver be represented with the output unit of the mobile user equipment. In this case, the content, timing of the activation of the at least one output unit of the mobile user device depending on the at least one predetermined criterion, e.g. selected from one or more qualitative and / or quantitative parameters of the predetermined criterion.

In other words, in particular only (according to predetermined criteria) selected prioritized information can be transmitted and / or (according to predetermined criteria) prioritized controls of the output unit of the mobile user device.

Preferably, the activation of the at least one output unit of the mobile user device is selected depending on one or more predetermined criteria or qualitative or quantitative parameters of the predetermined criteria that claimed each appropriate level of perception and / or attention of the driver to the information to be transmitted and / or be directed to the environment of the vehicle, in particular at a convenient time selected or retrieved. In this case, for example, a statistic valid measure for people in the In general, for a particular person of the driver or for a particular class of person to which the driver belongs, taking into account the characteristics of his acting or reacting, eg a measure of his responsiveness

In this case, the driver can only be brought out of his employment to a significant extent only if this requires the situation, in particular the overall situation. For example, a portion of the driver's perception and / or attention may be directed to a particular traffic situation and / or need for action in the method, for example by controlling the output unit of the mobile user device. depending on predetermined criteria or other factors). In the case of non-urgent action requirements, e.g. Decision making required first a certain proportion of the perception, e.g. only a certain perceptual channel of the driver or a portion of his attention to the environment of the vehicle or on a driving posture are directed.

If there are several occupants in the vehicle, a mobile user device is typically also arranged in the vehicle per occupant. Thus, it is advantageous to distinguish these mobile user devices. Therefore, according to a further advantageous embodiment, a mobile user device is recognized in the interior of the vehicle as that of the occupant at the driver's seat, and the transmission of the information on the detected traffic situation and / or the at least one specific action required by the occupant to the (certain) detected mobile User device, preferably associated with at least one current driver, eg to the mobile user device of the occupant at the driver's seat.

According to a further optional refinement, an active display content of the mobile user device is reduced or edited, and / or a further display is displayed that at least partially represents a relevant traffic situation and / or a specific need for action of the driver of the vehicle associated with the traffic situation.

Preferably, the modification, in particular reduction and / or pausing of the content previously output by means of the mobile user equipment and / or the output of the occupant information with the middle of the mobile user equipment to at least one vehicle means, e.g. be determined with the sensor system of the vehicle determinable condition. Such a condition may e.g. indicate that the detected traffic situation corresponds to predefined criteria, in particular if a (safety) critical traffic situation and / or (safety) critical need for action is recognized.

The method may include preparing the data for the at least one detected traffic situation and / or for at least one action requirement. The processing can be carried out at least partially by means of the vehicle and / or at least partially by means of the mobile user device. In this case, for example, data of the sensor system of the vehicle can be processed, in particular analyzed, interpreted. Processing of the data here is in particular a filtering, e.g. an extraction of relevant facts and / or a highlighting of critical objects in the environment of the vehicle include. Furthermore, the preparation of the data may include determining a forecast for the near future, for example an extrapolation of at least part of the traffic situation and / or a need for action for the next few seconds.

The processing of the data preferably comprises determining information to be transmitted to the mobile user device and / or occupant information to be output thereon at the mobile user device, which relates to the traffic situation and / or the action required at a time in the near future, e.g. approximately, 1, 2, 3, 5, 10 seconds after the triggering of the output unit of the mobile user device is valid or optimized.

In particular, the information to be transmitted to the at least one mobile user device and / or the subsequently issued occupant information can relate to the traffic situation and / or the need for action which will apply (for example, according to an extrapolation of the traffic situation for the near future). Thus, after the accommodation of his eyes, e.g. for example, upon a dark environment of the vehicle after viewing a bright screen of the mobile user device, have occupant information that will apply (at least with a certain degree of probability) at about the time the accommodation is sufficiently completed. Thus, the driver of the vehicle can perceive the then prevailing traffic situation more or less seamlessly, quickly find the "connection", react or act.

For example, in at least two occupants in the vehicle an occupant and / or a particular mobile user device can be determined, which can transmit its perception and / or attention (at least with a high probability) better or faster to the real environment. Then at least one particular mobile user device becomes at least one transmitting information is transmitted and / or the subsequently issued to the mobile user device occupant information can be selected.

Preferably, a previous display, which has been observed or operated by the driver, for example, can be reduced, in particular minimized, with regard to its display area, display sharpness, virtually perceived proximity to the display. The reduction in this context may also include a complete shutdown, hiding or shifting to the background. Preferably, the at least one output unit of the mobile user device is controlled in such a way that a reduction and / or pausing of the previously output content occurs. For example, a reduction of the previously output contents to the more important peripheries and / or a symbolic representation of at least part of the contents, e.g. the display contents, audio contents, haptic and / or tactile-perceptible contents. For example, a virtual reality generated by the mobile user device, e.g. a video game will be paused. It can thereby be achieved that the driver's perception and / or attention is transmitted much more quickly to his real environment, in particular to the traffic situation or to a specific action, e.g. Operating action to be transmitted.

According to a further optional embodiment, different threshold values are distinguished with regard to the importance of the traffic situation and / or importance and urgency of the action requirement of the driver, and then different actuations of one or more output units of the mobile user equipment are carried out.

At different determined threshold values, different changes of the display of the mobile user device and / or different, e.g. different or differently strong tones and / or actuations of a haptic actuator, e.g. Vibration or another stimulus of the mobile user device causes. For example, if a particular, e.g. unwanted traffic situation develops slowly, in the case of information exceeding (e.g., not hurriedly) a first threshold, on the mobile user equipment an unobtrusive information display, e.g. also as a picture-in-picture display together or within another (previous) content, e.g. together or within another application on the mobile user device, e.g. are displayed. However, if the traffic situation requires an urgent, in particular an immediate reaction / action of the driver, in the case of information exceeding a second threshold (for example, urgent and important), depending on the determined need for action, a previous content, e.g. for example, the previous display can be minimized, greyed out, hidden, reduced to symbols. In this case, the at least one output unit of the mobile user device can be controlled. The output unit can be controlled in such a way that the information to be transmitted at least partially uses the resources that were used by the previous content. For example, the proportion of the display area and / or audio frequency bands or time intervals for outputting said occupant information may be required by means of a reduction of the previous content and / or the release of the corresponding resources. In particular, e.g. depending on one or more predetermined criteria, a distribution of the resources between an occupant information to be output and one or more previous, active contents are executed on the mobile user device. Also, the resources of the mobile user equipment may be used in terms of computational power, memory or wireless data transmission in an analogous manner, e.g. in favor of the issue of occupant information.

According to another optional embodiment, the driver's need for action relates to the particular traffic situation and certain actions requested by the driver or recommended to the driver are represented in the display of the mobile user device.

Preferably, a previous display (which was observed or operated by the driver) can be reduced, in particular minimized, with regard to its display area, display sharpness, virtually perceived proximity to the display. In this context, the reduction can also be performed as a complete shutdown, hiding, or a shift to the background.

According to a further optional embodiment, it is recognized that the driver hears and / or telephones an audible content with the mobile user device, and auditory information is output by means of the mobile user device representing the information about the particular traffic situation detected and / or requested or recommended action of the driver in connection with the detected traffic situation.

Particularly preferably, alternatively or additionally, a vibration can also be output.

In summary, the method described above provides the following advantages:

The method contributes to an increase in traffic safety for the holder of a, in particular at least partially automated moving vehicle, its occupants and other road users.

Mobile user devices such as smartphones are very important to many people. By the method, these devices can be used while driving an at least partially automated moving vehicle, without the road safety is compromised. Conversely, with the invention it is possible to use the vehicle or certain vehicle functions while driving, while a mobile user device fulfills a (possibly also urgent or important) function.

Furthermore, steps of the method can be carried out by means of the mobile user device, so that the resources of the mobile user device (data, sensors, computing power) can be used and the possibly overloaded resources of the vehicle can be relieved.

The procedure contributes to a sense of security of other (not sitting on the driver's seat) inmates, as they may also be notified.

According to a further aspect, the invention is characterized by a mobile user device, in particular a device comprising at least one mobile user device, set up such a method for controlling a mobile user device of a driver of a vehicle, especially in an at least partially automated driving (at least partially automated driving ), wherein the mobile user device is set up to perform at least a part of the method for controlling an output unit of the mobile user device depending on a transmitted information. In this case, the mobile user device can be configured to execute at least a part of the method according to the first aspect.

For this purpose, the mobile application device can have a wired or wireless interface which is set up to carry out the method. Advantageously, alternatively or additionally, a transmission part and / or a sensor system and / or computing resources and / or a transceiver unit and / or authentication method of the mobile user device can be used or used in the method.
A structure of a (set up for the execution of the method) data connection with the vehicle can be made automatically, for example, if it is recognized that the driver uses his mobile user device while driving, especially under further predetermined conditions for driving context, etc.). For example, such a connection may also act as a proof of legitimacy of the use of the mobile user device while driving and / or as a technically-implemented requirement for the automation of the ride.

• - Mit Mitteln des Fahrzeugs ermittelte und an das mobile Anwendergerät übermittelte Information, insbesondere eine im sogenannten Push-Verfahren übermittelte Information, und/oder
• - eine durch das mobile Anwendergerät, z.B. Smartphone, insbesondere auf die Erfüllung vorausbestimmter Kriterien aus dem Fahrzeug ausgelesene, z.B. explizit abgerufene Information sein;

The information transmitted or exchanged between the vehicle or the vehicle unit and the at least one mobile user device can be:

• - Information determined by means of the vehicle and transmitted to the mobile user device, in particular information transmitted in the so-called push method, and / or
• a information read out of the vehicle, for example explicitly retrieved by the mobile user device, eg smartphone, in particular for the fulfillment of predetermined criteria;

The method can also distinguish between different types of mobile user equipment, e.g. different controls of the output units are provided in the different types of mobile user equipment.

For the purposes of this description, the mobile application device may include a smartphone, tablet, smart watch, smart closes, in particular a garment with an electronic device integrated in the garment, a voice computer, voice control system, motorcycle helmet, e.g. a motorcycle helmet with an integrated man-machine interface, a data glasses for the driver of the vehicle, a vehicle mitführbarer and connectable to the vehicle with a data interface vehicle computer, an external navigation device, or an analogous development of such devices.

For example, the control of one or more functions or contents of the mobile user device, depending on the execution of another feature of the method. For example, if it is detected that the user device is carried in an at least partially automated mobile or mobile motor vehicle and / or it is actively operated at the driver's seat, certain functions of the mobile user device, operated depending on the willingness to perform the method. For example, certain functions, in particular certain applications, apps, etc., can be operated only or to a greater extent while the vehicle is being driven, if a data connection is established for carrying out the method or a readiness for transmitting the said information or for executing the control of the output unit of the mobile user equipment is ensured.

The method is preferably carried out as a function of a variable representing the degree of automation of the drive of the vehicle. By way of example, the method is carried out only or predominantly above a first limit value and / or below a second one of the specified size.

The variables representing the degree of automation of the drive of the vehicle represent different aspects of the degree of automation, for example in the form of code values. The degree of automation or the degree of automation can characterize qualitative and / or quantitative measures of the degree of automation. For example, the degrees of automation known to the person skilled in the art can be taken into account on the scale 0-5, for example by VDA (= Association of German Automobile Manufacturers).

• - Längsführung des Fahrzeugs und/oder
• - Querführung des Fahrzeugs und/oder
• - Durchführung eines Spurwechsels und/oder
• - Durchführung eines Überholvorgangs und/oder
• - Fahrerinformation, insbesondere im Zusammenhang mit der Fahrzeugführung.

Different aspects of the degree of automation of the drive of the vehicle can each be appropriately taken into account. In particular, aspects of the degree of automation that are activated or operated at least partially independently of one another can be taken into account individually or cumulatively. In this case, automation levels for at least two different aspects of the automation of the movement of the vehicle and / or for two or more different driver assistance functions of the vehicle can be used, for example

• - Longitudinal guidance of the vehicle and / or
• - Transverse guidance of the vehicle and / or
• - Carrying out a lane change and / or
• - Carrying out an overtaking process and / or
• Driver information, in particular in connection with the vehicle guidance.

For example, the degree of automation or the variable representing the degree of automation of the drive of the vehicle may be at least partially determined with reference to a preceding roadway section, e.g. be considered by 10, 20, 50, 100, 150 meters.

Preferably, with the invention, an operation of the mobile user device in the interior of the vehicle when driving the vehicle (this also includes a parking and maneuvering operation of the vehicle) addressed. This results in numerous explicitly described as well as other advantages easily understandable by the skilled person. For example, the mobile user device can be used while driving the vehicle, possibly also by the driver or the occupant at the driver's seat of the vehicle (for various purposes).

Alternatively or additionally, the method can also be operated such that the mobile user device is at least temporarily outside the vehicle, in particular in the vicinity of the vehicle. For example, the mobile user device may be operated while said vehicle is performing an at least partially automated parking or maneuvering operation. That the occupant of the vehicle may e.g. temporarily outside the vehicle.

Even if this document refers to a "driver", it can also be applied to a plurality of drivers or passengers with a right to drive, in particular a vehicle that is at least partially automated. According to the invention, a driver, an approximately equal second driver and / or a co-driver may be defined, e.g. a lower, subordinate or differently defined operating options and / or authorization to operate or control the vehicle holds. Such a role of, for example, the first driver, a second driver, a co-driver may be selected in the invention depending on the vehicle seat on which the at least one occupant sits. Also, such a role, e.g. Depending on the traffic situation and / or the need for action between at least two occupants of the vehicle can be divided.

One application here is that in the event of an (urgent) need for action identified by the vehicle, a co-driver is also notified if, for example, the driver has fallen asleep during highly automated driving.

To the mobile user equipment of another occupant, e.g. Information transmitted to the front passenger may in this case be output, for example, to occupant information which indicates a request to wake or refresh the driver and / or be a request to give the driver an indication of the driver's attention (eg to specific conditions inside or outside the vehicle) , If an urgent need for action exists and / or an occupant information can be output to the other occupants to take over at least one specific operating action of the vehicle, in particular one or more specific, e.g. within the information marked to perform operator actions in the vehicle.

I can distinguish a passenger information output by the mobile user device to the first driver and a second driver such that the shape, level of detail, corresponding illustrations and comments depend on the Age, driving skills, driving authorization, responsibility for the present ride are chosen differently. For example, the occupant information output to the said additional occupant, who himself does not have any driver training or driving license (as opposed to the information to the driver), comprises an action instruction, eg for carrying out an operator action.

Also, the control of the output unit of the mobile user equipment of a second driver may be dependent on the actual response to the control of the output unit of the mobile user equipment of the first driver or depending on the further information from the mobile user equipment of the first driver.

In particular, a particular occupant may be considered a particular person, e.g. the owner of the particular mobile user device, or as an occupant at a particular seat, e.g. be recognized in the passenger seat of the vehicle. The respective driver information or occupant information can then be suitably generated and / or appropriately addressed. In this case, the occupant information for a further (second) driver may be a second occupant information that differs, for example, from the (first) occupant information for the (first) driver and / or time offset from the first occupant information to the second mobile user device ( the second driver) is output.

In the case of a nearly fully automated drive of the vehicle, an occupant may be accepted as the (first or second) driver. For example, a passenger of an at least largely automated taxi or shuttle vehicle in the context of the invention may be considered a driver.

Preferably, the activation of the mobile user device or the output unit of the mobile user device in the specified manner is no longer carried out or the change caused by the drive is no longer effected, canceled, for example. explicitly canceled, if it is determined that the determined traffic situation allows (again) an increased attention to the mobile user device or content or interactions at the mobile user device that is independent of the current ride, driving context, vehicle. For example, if no attention of the driver to the environment of the vehicle, to one or more driving tasks is no longer required (unconditionally or urgently), or if there is no longer a need for action, at least one output unit will no longer cause any changed output.

For example, it can be determined that a criticism, urgency, danger potential, the determined, in particular predicated, traffic situation can be found, for example, in compared to a predetermined amount or in comparison to an expectation has decreased or at least with a high probability, will decrease. In particular, information can be determined and transmitted to the mobile user device, which (explicitly) indicates that the change caused by the drive should no longer be effected, canceled, e.g. should be explicitly canceled in whole or in stages. In other words, (explicit) information to the mobile user device can be transmitted in the process, which are transmitted a kind of "all clear". Thereupon, a direct or indirect control of the output unit of the mobile user device can be canceled or carried out such that at least a reduction of the previously caused changes takes place. For example, the previously output contents can then be restored or output (for example) with the previous parameters and / or output planned (or queued or interrupted) for output. In this case, canceling or no longer in the described manner the driving and / or the output of a previously changed (until now interrupted, reduced, paused) content, e.g. in a most recent manner, depending on the (new or updated) information transmitted to the mobile user equipment.

According to a further aspect, the invention is characterized by a computer program, in particular a computer program product comprising a computer program, wherein the computer program is designed to carry out the method according to one of claims 1-12 when executed on a computing unit of the vehicle and / or the mobile user device ,

According to a further aspect, the invention is characterized by a vehicle unit or a vehicle comprising said vehicle unit. By way of example, the vehicle unit may be a control unit of the vehicle, a built-in computing unit installed in the vehicle and / or connected to the vehicle, wherein the vehicle unit is configured to execute at least the method together with a mobile user terminal that can be carried in the vehicle.

Also, the invention can be applied to an at least partially or mostly manually moving (or mobile) vehicle. For example, the method can also be used with a a driver assistance system supported or supportable ride the vehicle be executable.
