Definitions
- the disclosure relates to an assistance in a means of transport, in particular in a motor vehicle, with a camera-based recognition of an activity of a user of the means of transport in a passenger compartment of the means of transport based on image data from a camera unit and an adapted execution of a further function by a functional unit.
- a means of transport i.e. a passenger compartment of a means of transport, such as in a passenger car or a truck, but also in a drone taxi or a gondola, it is becoming increasingly important to identify the activities, in particular activities for which assistance is available from the means of transport and/or activities that are not permitted when using the means of transport in the respective role of the user, and possible
- Distractions of users ie the vehicle occupants and in particular a to record the data of the user responsible for driving the means of transport.
- This makes it possible, for example, to optimize the transfer of driving responsibility from a navigation and/or control unit of a (partially) automated means of transport back to the driver, to adapt assistance systems of the means of transport to the respective activity of the user, for example by proactively offering functions, or to take targeted safety measures, such as deploying an airbag adapted to a respective recognized body pose.
- Driving functions, comfort functions and safety functions in the means of transport can thus be improved based on a respective recognized activity.
- the comfort functions can in particular include entertainment functions such as gaming functions and/or communication functions and/or work functions.
- the safety functions can in particular include a monitoring function to ensure appropriate behavior if there is no person with driving or leadership responsibility (driver) and/or no staff in an autonomously driving means of transport.
- a so-called body pose activity recognition is basically known, in which people are detected in the image data generated by the cameras using one or more cameras in the passenger compartment and a configuration of the skeleton of each of the detected people is recognized in three dimensions, i.e. calculated according to a predetermined anatomical model.
- the passenger compartment can refer to a closed space intended for accommodating users, such as the passenger compartment of a sedan and/or a partially open space intended for accommodating users, such as the passenger compartment of a convertible and/or an open space intended for accommodating users, such as the passenger compartment of a motorcycle.
- the respective activity is then recognized or classified, i.e.
- the recognition can also include a hierarchical class model, in which classes can each have one or more subclasses.
- the class "uses phone” can be defined as subclasses "uses phone with Mobile phone to ear” and “using hands-free phone”.
- end-to-end recognition in which the image data from the cameras is fed directly into a classifier and activities are recognized accordingly without intermediate steps such as the analysis of the body pose described.
- One aspect relates to a method for operating an assistance system in a means of transport, in particular a driver assistance system in a means of transport.
- the means of transport can be an airborne means of transport such as a drone taxi or a gondola and/or a waterborne means of transport such as a ship and/or a land-based means of transport such as a motor vehicle, i.e. a passenger car and/or a truck and/or a bus.
- One method step is a camera-based detection of an activity of a user of the means of transport, in particular of a user who at least temporarily bears the management responsibility for the means of transport, in a passenger compartment of the means of transport. This is carried out using image data from a camera unit by a computing unit.
- a further step in the method is to estimate a time duration for the detected activity, ie to estimate the length of the period in which the Users of the recognized activity pursue a respective prediction by the computing unit. This can be done empirically, for example, based on activities specifically recognized for the user in the past and/or according to a stored specification.
- the duration can also be estimated based on additional information provided to the computing unit; for example, many articles provided on the Internet provide an expected reading time as additional information. Estimating can therefore be understood as a calculation based on certain assumptions.
- a mental load associated with the activity which can also be understood in the sense of "cognitive involvement" can also be estimated and/or a fallback time, i.e.
- the fallback time can therefore be understood as the time required for a transition from the recognized activity to the other activity after a warning from the means of transport.
- Mental load and fallback time can be estimated independently of one another or together, for example the fallback time can be estimated based on the mental load. The respective models and/or empirical data can be used for the estimation.
- a further method step is providing activity data, which specify the recognized activity and the estimated duration of the recognized activity and the activity associated with the activity in the activity data, to at least one functional unit.
- the activity data can specify the estimated mental strain associated with the respective recognized activity and/or the relapse time associated with the respective recognized activity.
- a respective function is then carried out by the functional unit depending on the recognized activity specified in the activity data and/or the associated duration of the recognized activity and/or the estimated mental strain and/or the estimated relapse time.
- camera-based detection can be used to detect that the user is reading. If a longer duration is estimated for reading, for example reading an article, a book or e-mails, a lighting function of an interior lighting unit can be adjusted as a further functional unit, for example the brightness can be increased. If, on the other hand, a shorter duration is estimated for the activity, here reading, for example when reading an SMS, the lighting can be omitted in order to avoid the eyes adapting to reading and thus possibly promote safety.
- the execution of the function by the functional unit depending on the specified activity and/or the associated duration can therefore include checking the length of the duration, with the function of the further functional unit in particular being adjusted, preferably automatically adjusted, if the estimated duration exceeds a predetermined limit duration. This can be at least 15 seconds, for example.
- assistance systems can adapt better than before to the respective activity of the user and it is therefore also possible to proactively offer functions or to select the right time for proactive messages, in particular requests for action for the user.
- a possible transfer of driving responsibility from a (partially) automated means of transport back to the driver can be optimized in this way, as will be explained in more detail below.
- the effect of safety measures can also be improved in this way, for example by taking into account a body pose typical for a certain activity.
- the recognized activity can therefore serve as the basis for many use cases. If the user wants to read a book, for example, this can be recognized and a reading light can be switched on automatically or the reading intention can be taken into account when dimming the interior lighting.
- the navigation unit must warn in good time or wait until the phone call is over. If a particular activity is detected for the user in the driver and/or passenger seat that requires a high level of concentration, it may be better, for example, for a fully automated vehicle not to choose a route that is dynamically intensive, which could irritate or distract the user, or even cause nausea (“mo- By estimating the duration of detected activities, settings can be made automatically that previously had to be made manually by the driver or another user. Manual interventions in the functions of the vehicle are reduced accordingly.
- This not only contributes to increased comfort, but can also significantly increase safety, as the assistance system can take more information into account when making the appropriate settings and, in particular, when planning a route, for example, a longer time horizon can be viewed than is possible for a human user.
- the detected activity is stored with the estimated and/or otherwise recorded associated duration and/or a specification of the mental strain associated with the detected activity and/or the relapse time associated with the detected activity in an activity database by a storage unit.
- the activity database can also contain further information, for example typical start times or locations for the activities. This can be done, for example, using so-called artificial intelligence (KI), ie a trained or learning algorithm that recognizes recurring patterns, in particular characteristics such as a typical duration of recurring patterns of recognized activities.
- the Kl can include a neural network or be such a neural network.
- the duration is estimated based on the same and/or similar activities according to a given similarity criterion and the duration that is stored for the same or similar activity.
- the similarity criterion can be implicitly specified with the structure of the learned algorithm, in particular with the neural connections of the neural network.
- the activity database can also contain sequences of different activities that are to be expected with a corresponding probability. This can also be done on a user-specific basis. The estimation of the duration is improved accordingly, especially on a user-specific basis, and further planning is also made possible, for example in the form of to-do lists with a series of activities and with the durations of the different activities in the means of transport for the respective users.
- the activity manager can thus be enabled to recognize not only for the users, i.e. occupants of the means of transport, which activity they are pursuing and how long they will pursue this activity, but also which activity they will most likely pursue afterwards and how long the subsequent activities will each take approximately, i.e. estimated.
- the activity manager can accordingly predict user behavior ("behavior prediction"), i.e. expand activity recognition to intention recognition.
- one of the at least one functional unit is a navigation unit.
- Carrying out the function of the navigation unit includes at least partially autonomous control, i.e. partially autonomous or fully autonomous control, of a driving function of the means of transport according to a predetermined route, in particular longitudinal guidance such as a speed specification.
- the at least partially autonomous control of the driving function can take place here in particular in the form of controlling a driving function according to SAE levels 1-5 according to J3016 of January 16, 2014, updated on April 30, 2021, or include such control of a driving function according to the respective SAE level; accordingly, partially autonomous driving also includes so-called assisted driving in In the sense of the SAE level.
- the driving function of the means of transport can be adapted depending on the detected activity and/or the associated duration and/or the associated mental strain and/or the recovery time of the activity data provided (based on a previous specification, for example before the activity was detected and/or before the duration/mental strain/recovery time of the activity was estimated) in such a way that the user is permitted to complete the detected activity in accordance with a stored legal or other, for example physiologically determined, specification for semi-autonomous control.
- a stored legal or other for example physiologically determined, specification for semi-autonomous control.
- the functional unit in this case the navigation unit, maintains the boundary conditions within its sphere of influence which allow the user's activity, i.e. are a prerequisite for the user's activity (within specified limits). The user is therefore not prompted or forced to interrupt his activity in accordance with the stored specification by carrying out the function, in particular the at least semi-autonomous control, when following the specified route.
- the driving function of the means of transport can be adapted to the detected activity, for example reading an article or processing emails on a given route, by adjusting the speed, i.e. in this case reduced, in such a way that the detected activity is expected to be completed, i.e. according to the estimated duration, when the end of the motorway is reached, i.e. at the end of a section of the route that runs on the motorway.
- the speed i.e. in this case reduced
- the navigation unit is also certified to autonomously control the driving function of the means of transport for a subsequent section of the route, which, for example, does not run on a motorway but on a winding country road, the slowing down on the motorway and the resulting completion of the activity, for example due to a Other requirements such as a physiological requirement or simply a stored preference of the user can prevent the occurrence of nausea, which often occurs when reading on winding roads. This further improves comfort and safety.
- carrying out the function includes specifying the route for the at least partially autonomous control of the driving function of the means of transport.
- Specifying the route also includes specifying a previously specified route, i.e. adapting a previously specified route, an original route.
- the specification can be fully automatic or semi-automatic, for example after the user has approved an original route as the then specified route.
- This is also known from known route guidance systems in which a user is suggested different route alternatives from which the user can select one or one of the routes is selected automatically, for example after a specified time has elapsed.
- original routes can be specified again, i.e. adapted, for example, to changed traffic conditions.
- the route is specified, in particular adapted, depending on the activity detected and/or the associated duration and/or the associated mental strain and/or the recovery time of the activity data provided, in such a way that the user is permitted to complete the detected activity in accordance with the stored legal or other requirements for semi-autonomous control.
- the route can also be adapted to changed activities, for example if a user does not undertake the activity planned or expected by the activity manager as described below, but rather a different one.
- an existing or originally taken route can also be re-specified, i.e. adapted. when an activity such as processing an email is detected unexpectedly, i.e. contrary to a prediction or plan. This also improves comfort and safety in the vehicle.
- At least one activity planned by the user is recorded with an estimate of the respective associated duration and/or the associated mental strain and/or the fallback time for the planned, i.e. expected future activity.
- the recording is carried out via a recording unit, in particular using the activity database.
- the recording unit can comprise an input unit for an input by the user and/or an interface unit, for example to access the user's appointment calendar, email program or similar information sources, or can be coupled to the corresponding units.
- the recording unit records the one or more planned activities from a prediction unit, which is designed to predict the at least one activity planned by the user.
- the prediction unit can use a KI-based algorithm, which, for example, based on the activity database, makes a prediction for the journey, in particular for a specific route and/or the specific time period, of the user's expected activity.
- the user can also provide a corresponding to-do list of planned activities to the recording unit via the input unit or the interface unit.
- the route is specified depending on the activity planned by the user and/or the respective associated duration and/or the associated mental strain and/or the relapse time.
- a user can plan to work on an email on the way to work as an activity. This can be recorded by the recording unit when the user explicitly enters this, for example via a to-do list, or via the prediction unit, which knows, for example, that the user usually works on emails on the way to work on weekdays.
- a route can be specified from the outset that leads via the motorway and enables fully automatic control, for example although this is slower than an alternative route through a built-up area due to traffic jams.
- the route via the motorway is preferred and suggested to the user, if not automatically approved for route guidance, in order to allow the user to pursue and complete the usual planned activity. This also increases the comfort and safety of the means of transport.
- specifying the route includes identifying at least one route section with constant or essentially constant requirements for the user, i.e. the same or essentially constant boundary conditions for the activity, such as a provisional travel duration assigned to the respective route section, comparing the at least one time duration assigned to the planned activity or activities with the at least one provisional travel duration, assigning the one or more planned activities to one or more respective route sections based on a comparison result for the time duration and the travel duration (which can be the provisional travel duration or, as explained below, an adjusted travel duration), and displaying the specified route with the at least one route section depending on the at least one assigned activity, in particular with a specific identifier for the at least one route section for the assigned activity.
- selecting the specified route for the at least partially autonomous control can be done automatically, for example by means of a timer as is known for the fastest route, or manually by the user.
- the constant or essentially constant requirements i.e. the requirements that remain the same apart from a predetermined deviation, can correspond in particular to a stored legal and/or physiological requirement, as described above, and preferably relate to a requirement at least set by the user responsible for driving the vehicle.
- the requirements can include a (particularly user-specific) specified maximum permissible lateral and/or longitudinal acceleration.
- a lateral and/or longitudinal acceleration to be expected on the respective route section can be calculated, for example, from a known road course with the respective travel speeds assumed.
- a route to the customer provided by a conventional route planner, for example, can be specified as the original route and then adapted depending on the planned activity(s), in this case the planned or expected processing of emails.
- the new route may have many distractions in an initial section of the route, because the user does not drive onto the nearby motorway as usual, but instead first needs to take a longer journey to another motorway.
- the estimated duration of processing emails is compared with the respective travel times on the corresponding route sections and the corresponding requirements for the user. For example, it may be impossible for a user to check their emails while driving through a town or on a country road because the navigation unit is not certified for SAE Level 3 compliant driving.
- Email processing is then assigned to the later section of the route and the corresponding route with the later email processing is displayed to the user. The user can then see where and when on the planned route they can check their emails. This further improves safety and comfort in the means of transport.
- a stored urgency of the respective activity i.e. an explicit or implicit appointment request that is linked to the respective activity, for example in the activities database
- this can be done by assigning more urgent activities to route sections that are arranged within the route specified by the navigation unit before route sections that are assigned to less urgent activities.
- the user can plan a business phone call with high urgency on the day of travel. This is then assigned to a route section, for example, which would be assigned to email processing without the phone call.
- a private phone call without urgency is assigned to a route section after email processing if email processing is set to increased (but not high) urgency. This also contributes to improved use of time and clearer focus and thus to improved comfort and increased safety in the means of transport.
- the provisional travel duration of one or more route sections can be adapted to the respective duration of one or more activities if adjusting the provisional travel duration leads to an improved result of the assignment in terms of a predetermined optimality criterion. This can be done in particular by adjusting a speed on the corresponding route section. For example, if a route section that is suitable for a planned activity except for a deviation in the duration that does not exceed a predetermined limit value, can be made suitable by reducing the speed, i.e. adapted to the activity. In return, for example, a speed on another route section can then preferably be increased so that the total travel time can remain unchanged.
- the result can be improved in terms of the predetermined optimality criterion, since the planned activity is still carried out and completed in the means of transport, so that the total time spent on the trip plus the activity is less than if the activity were carried out after the trip.
- adjusting the provisional travel duration can also be specified so that this is only done for activities of a given urgency, which is particularly advantageous.
- experience shows that there may be enough time on the way to work, for example due to traffic jams, to process emails on the motorway section of the route. If, for example, the travel time on the motorway is reduced If, for example, there is no traffic jam, the activity - in this case, processing emails - could be assigned to a different section of the route. If this is not possible or is not optimal due to other activities planned for the route, for example, the provisional journey time can be adjusted accordingly, for example by reducing the speed of the vehicle on the motorway section of the route, thus creating sufficient time for processing emails while driving on the motorway. The total journey time will then be increased, but the result will be improved because the activities planned for the journey can be completed. Overall, time is used optimally and time is actually saved. This also contributes to increased relaxation and therefore comfort and safety in the vehicle.
- the specification of the route includes the specification of at least two alternative routes that differ from one another, with the identification, comparison, assignment and display taking place for the different alternative routes.
- the different alternative routes have a different chronological sequence of the planned activities.
- the user can decide whether he wants, for example, the faster route with email processing at the beginning or the slower route in which the business phone call is planned first.
- the selection can also be made automatically, for example based on the recognized activity, so that the route matches the recognized activity: If the user starts processing emails, in this example the faster alternative route is automatically selected; if he starts making a phone call, the slower alternative route is automatically selected. This also leads to a more intuitive assistance function, and thus increases comfort and safety in the means of transport.
- the activity data is provided to several functional units that function independently of one another.
- a central activity management or a central activity manager is thus implemented, through which independent Functional units that function independently of one another react coherently to the behavior of the user(s).
- the activity data can be sent and distributed in various ways, e.g. via a multi-broadcast to the entire means of transport, ie many or all of the functional units of the means of transport, or via a publish/subscribe procedure to selected individual functional units.
- the infrastructure can be either the CAN bus or equivalents or alternatives such as Ethernet.
- the respective assistance systems with their functional units can accordingly access the activity data and react to it accordingly.
- Route planners can use the activity data to adapt driving to the interior activities both from a comfort perspective (cf.
- Interior safety systems can use the activity data, for example, to be able to activate airbags adaptively, lighting assistance systems to take the respective activities of the occupants into account when the lighting changes, voice-based assistance systems to avoid interrupting ongoing conversations or phone calls between the occupants and to plan dialogues in advance, for example when announcements or queries are made by the navigation unit.
- the provision can be made to a functional unit for a voice-based assistance function, which can also be or include the navigation unit, and a voice output function can be carried out as the or one of the functions to be carried out or carried out with a delay depending on the activity specified in the activity data and/or the associated duration in order not to interrupt conversations or phone calls of the occupants.
- the provision can also be made to at least one functional unit for a safety function, in particular for an interior safety function such as an airbag triggering function and/or at least one functional unit for a comfort function, in particular an interior lighting function such as a reading light function. All of this contributes to increased comfort and improved safety in the vehicle.
- the activity manager or activity management could not operate centrally, but be installed separately in the various assistance systems, i.e. independently of each other or instantiated in the software. and only act in a way that is useful for the functioning of the respective individual assistance systems, i.e. the proposed procedure is carried out in independent instances.
- the navigation unit would be a self-contained system that uses the cameras in the vehicle to recognize and process the activities of the occupants.
- the other systems for example functional units for an airbag triggering function, a reading light function and a voice-based assistance function, would do the same. However, all systems would have in common that the respective activities, including the associated duration, are recognized or estimated in order not only to check whether activities are present, but also to be able to plan ahead.
- a further aspect relates to an assistance system, in particular a driver assistance system, for a means of transport, in particular for a motor vehicle.
- the assistance system has a camera unit with one or more cameras for generating image data of an activity of a user of the means of transport in a passenger compartment of the means of transport, and a computing unit with one or more computers for recognizing the activity of the user in the passenger compartment based on the generated image data.
- the computing unit is designed to estimate a time duration for the recognized activity and to provide activity data, which specify the recognized activity and the estimated time duration for the recognized activity, to at least one functional unit.
- the functional unit which can be part of the assistance system but does not have to be, is designed accordingly to carry out at least one function depending on the activity specified in the activity data and/or the associated duration.
- Fig. 1 shows an exemplary embodiment of an assistance system in a means of transport.
- the assistance system 1 is installed in a motor vehicle as a means of transport 2. It comprises a camera unit 3 for generating image data of an activity of a user 4 of the means of transport 2 in a passenger compartment 5 of the means of transport 2.
- the assistance system 1 also has a computing unit 6 for recognizing the activity of the user in the passenger compartment 5 based on the generated image data.
- the computing unit 6 is designed to estimate a time duration for the recognized activity and to provide activity data which specify the recognized activity and the estimated time duration for the recognized activity to at least one functional unit 7.
- the further functional unit 7 is designed to carry out a function depending on the activity specified in the activity data and the associated duration.
- the functional unit 7 is designed as a navigation unit and is coupled to a steering unit 8 for steering the means of transport 2, a drive unit 10 for driving the means of transport 2, a braking unit 11 for braking the means of transport 2 and an interactive display unit 9 for displaying a route and receiving an input from the user 2.
- the computing unit 6 is additionally coupled to a storage unit 12, which is designed to store the recognized activity with the estimated and/or a recorded associated time duration in an activity database. Accordingly, the estimation of the time duration is carried out based on the same and/or similar activities according to a predetermined similarity criterion and the time duration which is stored for the same or similar activity in the storage unit 12.
- the assessment The similarity can be determined, for example, using Kl-based methods, i.e. based on a learned or trained algorithm.
- the assistance system thus serves as an activity manager, which is able to recognize for the user(s) 4, i.e. occupants of the means of transport 2, which activity they are pursuing, and preferably also which subsequent activity they will most likely pursue after this and approximately how long the respective activities will last.
- the activity manager can also be used to assign a to-do list of the user 2, in particular a driver, to the most suitable route or route sections. This is particularly relevant for truck drivers and other drivers who are supervised by a dispatcher.
- the level of automation possible on the respective route section i.e.
- the assistance system 1 shown enables a to-do list to be included in the route planning in order to complete the activities listed on the to-do list during the journey or trip. This can be displayed on a route plan of the navigation unit, for example, in a similar way to how traffic jam sections are displayed.
- the activity manager can provide interfaces to all common vehicle systems, i.e. CAN bus, Ethernet and the like, in order to be able to record the activities of the user(s) 4 as a central element and to make them available to all other connected systems with their corresponding functional units. This makes it possible for a (partially) automated vehicle to adapt the route to the current state of the user and to plan it in advance, for example to avoid motion sickness.
- the navigation unit can synchronize route sections with the activities of the users 4 in the interior 5 and adjust the route if necessary.
- the navigation unit can The navigation unit can compare route sections with the requirements for SAE-level compliant behavior and check whether all users, especially the driver, comply with these requirements.
- the (partially) automated vehicle 2 should take over driving responsibility on a certain section of the route.
- the route section requires a certain behavior from user 2 so that he or she behaves in accordance with the automation level and the transfer of driving responsibility to the motor vehicle 2 is permitted. If the user 4 does not behave accordingly, the navigation unit or its control function can intervene, warn the users in good time or choose a different route.
- the aim here is to establish a match between the activities of the user 4 and the requirements of the motor vehicle 2 and the route.
- the recognition of the activity and the comparison with level-compliant behavior can also be used for safety purposes in, for example, automated taxis, Uber services, automated long-distance transport or similar.
- the activity manager can also save the recognized activities and, if required, provide a list of past activities for each user 4. This can be advantageous, for example, for a voice assistance function which could proactively address the user 4 when approaching a rest stop and suggest that they take a break after a journey of a specified minimum length. However, if it has recently been detected, i.e.
- the activities identified can be shown as a proportion of the total time, such as the duration of the journey.
- the activity data can show that user 4 spent 20% of the driving time with a passenger or interacted with infotainment for 10% of the driving time.
- the basis of the approach shown here is therefore the automated recognition of the activities of the users, preferably all users of a means of transport, as well as the creation of correlated durations of the respective activities for planning in the the respective need of the assistance system and, if necessary, an additional necessary prediction of the follow-up activity or several probable follow-up activities.
- the detection of the activities is preferably carried out centrally for all users 4, ideally kept in a corresponding activity database and transmitted to the
