  • Increasingly, the development of data networks and system functions is being considered, using a more flexible topology and a flexible, variable collection of services.
  • Static bus systems, such as those used today in vehicles, are not capable of flexible administration of services due to their static network ports and network addresses.
  • The object of the invention is therefore to provide a method for improved management of communication channels / notification services, which are required for the execution of an automated process. This object is achieved by the data processing method for managing communication channels for communication with a vehicle driver a vehicle and / or notification services for notifying a driver in a vehicle according to claim 1 solved. Embodiments and developments of the inventive concept are the subject of dependent claims.
  • A data processing method for managing communication channels required for the execution of an automated process for communication with a driver of a vehicle and / or notification services for notifying a vehicle driver by a central authority in the vehicle, a data processing system and a motor vehicle having a data processing system are disclosed.
  • The data processing method for managing communication channels required for the execution of an automated process for communicating with a driver of a vehicle and / or notification services for notifying a vehicle driver by a central authority in the vehicle is characterized in that it comprises at least the following steps, namely: the process is started. Then, the on-board center of a local vehicle network sends a request for presence of network subscribers to the network subscribers in the vehicle network, where both devices and / or instances of the vehicle network and in-reach mobile devices connected to the vehicle network are network subscribers. And in this step, the central entity also asks the network participants which communication channels / notification services are available on the respective network subscriber and queries parameters for the communication channels / notification services available on the respective network subscriber. Furthermore, in this step, the central entity also queries parameters for the network communication with the respective network participant. Then, the network participants respond to the central entity and transmit to the central entity which communication channels / notification services are available on the respective network participant and transmit the requested parameters to the communication channels / notification services available on the respective network participant. And in this step, the network participants in each case transmit the parameters of the network communication requested by the central instance with the respective network participant. Then, the central entity selects which of the available communication channels / notification services are used for the started process, the process being aborted and / or a notification issued to the vehicle operator when a predetermined minimum number of available communication channels / notification services is undercut or if one or more certain required communication channels / notification services are not available. From then on, the central entity repeatedly sends a query to the availability of the selected for use communication channels / notification services to the respective network participants. The previous step, that the central entity repeatedly issues an inquiry of availability, is repeated until the end of the process, whereby the process is aborted and / or a notification is issued to the vehicle operator when, during the course of the process, a predetermined minimum number of available communication channels / Messaging services or if one or more particular required communication channels / messaging services are unavailable.
  • The data processing system for executing the data processing method is designed such that it has at least one central entity and at least one network participant who has at least one communication channel for communication with a vehicle driver of a vehicle and / or a notification service for notifying a vehicle driver in a vehicle network.
  • The motor vehicle is equipped with a data processing system for carrying out the data processing method.
  • Particular embodiments are subject of the dependent claims.
  • Communication channels for communication with a driver of a vehicle may be, for example, visual, auditory or haptic channels. For example, visual channels may include output on a display (such as a screen, an infotainment display, a display in the center of the instrument panel of the vehicle in the so-called "center stack", in the instrument cluster, in a heads-up display), or signals from a vehicle Luminaire (eg interior lighting). Auditory channels can be, for example, an output of speech, sounds or sounds via a loudspeaker or also the horn. Haptic channels can be, for example, vibrations of wristwatches (for example, computer-equipped watches, so-called "smartwatches" or heart rate monitors), mobile telephones, tablet computers, seats, steering wheels or control buttons, but also deliberately output forces on steering wheels or pedals or control levers.
  • Notification services for notifying a vehicle driver may be realized, for example, by data processing programs and / or instances of data processing programs executing on the devices representing network subscribers in a vehicle network. In this case, for example, multiple instances of the same data processing program or even multiple instances of various data processing programs can be executed on one device; for example, about two notification Data processing programs that are running on a mobile network participant, such as a smartphone. Generally speaking, in the context of the present invention, a notification service means means by which, initiated by the central entity, a notification is issued to a vehicle driver via one or more communication channels for communication with a vehicle driver. For example, in the case of devices connected directly to the central entity, which may themselves have output means such as displays or loudspeakers, an output path of the central entity itself may fall under a notification service, whereby a data processing program would not necessarily have to be executed on another device. Notification services may also be implemented, for example, as data processing programs or data processing services, sometimes referred to as utilities or runtime services.
  • A central entity central to the method of the invention may also be distributed among multiple physical devices or distributed among different physical data processing layers or distributed among multiple instances of data processing programs. In the context of the method according to the invention, a central entity is therefore to be understood as a structure in which all services or channels assigned to the method are detected centrally.
  • Network-based network subscribers are understood to be network subscribers who run on devices permanently installed in the vehicle. Examples of permanently installed devices are for example the instrument cluster (also called instrument cluster) or also an integrated device for information and entertainment in the middle of the dashboard (also called "head unit"), a car radio, built-in media players, fixed to the vehicle associated screen devices for rear passengers, permanently installed sensors and sensor clusters, permanently installed redundant units, control units of the vehicle or even, for example, air conditioning control operating devices.
  • An automated process, as it is mentioned in the method according to the invention, is a process that is at least to some extent automated. Processes from the entire spectrum of automation levels are included: The degree of automation of the automated process ranges from slightly automated or assisted in the context of the method of the invention from semi-automated and highly automated to fully automated.
  • The vehicle network in the context of the invention refers to a network for data communication which is vehicle-mounted or vehicle-bound.
  • Network subscribers are to be understood as instances capable of network communication. It can thus be both data processing programs that communicate individually, as well as to physical computing devices.
  • Under motor vehicles fall in the context of the invention road vehicles but also mining vehicles and agricultural machinery and vehicles from the category motor vehicles.
  • Examples of an automated process may include ordering a field such as fertilizing, planting or sowing crops for cultivation, spreading water or crop protection, plowing or harvesting. An automated process may be, for example, a transport journey or a tunnel boring or a material removal in mining with regard to mining vehicles.
  • The repeated polling of the availability of the registered communication channels / notification services can take place, for example, at fixed intervals. Fixed time intervals can be regular as well as irregular time intervals. The time intervals can be set individually for each individual network subscriber, ie, for example, also different for different network subscribers, or also, for example, for all network subscribers. The time intervals can be determined, for example, by the characteristic circumstances of the network communication, of the respective network participant, or else by the central entity. Fixed time intervals can also be cyclic, for example. Instead of a fixed time, for example, time windows can be set. For example, after submitting a repeated request to the central entity, a timer, ie, a timer running down the time window or a timer, could be started until when the responses from the respective network subscribers are expected to operate properly. It is also possible, for example, to assign separate time slots of individual length to the different network subscribers. In this case, for example, the answers received within the respective time window at the central instance, could be considered valid. In addition, for example, non-incoming responses could be seen as unavailability of a service or channel or network participant. Furthermore, only after the Time window incoming messages are registered and used for troubleshooting.
  • In an exemplary case, in a method, even after the first selection of the communication channels and / or notification services to be used, additional unselected additional communication channels / notification services may be selected for use during execution of the automated process and added to the current process or selected communication channels for use. Notification services during the execution of the automated process to be replaced by not yet selected additional communication channels / notification services or removed for use selected communication channels / notification services during the execution of the automated process. In short, in such a case, during the execution of an automated process, it can be changed which channels or services are selected for use, i. H. The group of services and / or channels selected for use may be supplemented by additional services / channels, services / channels may be replaced or may be omitted. This applies to physical devices (for example, by bringing a device into range by turning a device on after charging, by turning a device into an inactive mode, such as a power saving mode, or being reactivated from such a mode.) But also software functions and services, which may be available (eg, by activating a data processing program or data service, for example, after installation of such) or disabled (by shutting down a program, putting it in the background, or suffering a crash).
  • Communication paths of the network communication can be, for example, transmission / reception routes in the vehicle network.
  • Seamless redundancy can be realized, for example, by assigning at least two network ports to the network communication per network participant or per physical network device. Seamless means that a replacement for a failing service / channel occurs without any interruption of the procedure.
  • Under the phrase to send automatically, with regard to the network subscribers, it should be understood that there does not necessarily have to be a request from the central entity for the network subscribers to send a notification to, for example, the network or certain network subscribers, such as the network. B. the central instance, can send. To enable network communication with time-synchronous clocking in the vehicle network, for example, all network subscribers can have at least one timer.
  • Parameters of the communication channels for communication with the driver of the vehicle, for example, to understand: the type of communication with the driver (auditory, visual, haptic), a maximum or minimum frequency, z. An audible output, a volume of an output, a brightness of a visual output, an optical or acoustic frequency range of an output, the intensity of a haptic output, a duration of an output, an availability of the channels depending on other circumstances (e.g. no dependence or not active in tunnels or influenced by outside noise or light from outside the vehicle) or the so-called driver relation (ie the relationship or immediacy of how the communication with the driver takes place, for example being "close-fitting" in the case of a worn wristwatch may be "in the field of view" for elements in the instrument cluster, and may also include the distance to the driver, for example in the case of a laptop computer in the passenger seat).
  • The parameters of the notification services for notifying the driver of the vehicle include, for example, a registration status or also registration status of the notification services (active, inactive, standby), the degree of redundancy of the notification services for the respective communication channel (in the case of approximately several, possibly identical, instances of a service running on the same device), availability of services depending on other circumstances (as explained in the previous paragraph for communication channels).
  • Process parameters of the individual running automated process may, for example, be: a necessary availability of communication channels / notification services (eg minimum requirements as to how many and / or which communication channels / notification services are required), a selection status of services / channels (for use selected, not selected for use), a response status of services / channels (answer is at the central instance, answer is pending), a usage status or execution status (ie, for example, whether a selected service is used or executed, for example, a current time or the whole process), the number of network communication paths available for network communication, or a retained communication bandwidth, the central instance's specified time intervals of the request, an actual or minimum required duration of availability of communication channels / notification services, the execution time of the process, the distance traveled during the execution of the process.
  • Physical devices may include, for example, permanently installed vehicle components, retrofitted vehicle components or mobile, d. H. portable, devices. For example, a physical device may itself be a network participant, but for example, one or more instances of data processing programs may be executed on a physical device, which may then be the network subscribers in the vehicle network. In this case, the physical device itself would not necessarily be network subscribers, but it could also be network subscribers.
  • Device parameters of a physical device can be, for example, its spatial allocation in relation to the driver or the physical location of the device within the vehicle, the type of energy supply (for example by means of battery, battery or on-board supply), possibly redundant energy supply, energy requirement, or characteristic features of the energy supply ( such as, for example, the individual terminal or wiring harness), operating state or operating status of the device (active, standby, disabled), or the relationship with the driver for its perception (eg, whether in field of view or in range of hearing is or not). Parameters of the network communication include, for example, the bandwidth allocated to a communication path or a device or a service or a channel or associated network communication paths (and possibly also, for example, the degree of redundancy of the channels), the transmission runtime of a packet in the network communication, network ports and network addresses, the type and / or signal quality of communication paths (radio link, cable link, bit error rate), the transmission bandwidth of a communication path, a latency of transmission over a communication path (and possibly, for example, the minimum latency for a worst case), the presence of a time synchronization (synchronized, non-synchronized).
  • Mobile network subscribers are mobile devices within range of the vehicle network that are connected to the vehicle network. Mobile network subscribers may include, for example, cell phones (including smart phones), tablet computers, PDAs, e-book readers, laptop computers, notebook computers, netbooks, portable media players, wearable computer systems (so-called "wearables", including, but not limited to, wristwatches Computer functionality - so-called "smartwatches" - but also fitness trackers, heart rate monitors and medical devices such as hearing aids fall).
  • The fact that the central entity selects which of the available communication channels / notification services are used for the automated process also determines which network subscribers (ie in turn devices / instances) are used.
  • In an exemplary method according to the invention, to bridge bottlenecks, the network communication may be timed-synchronous and / or one or more individual communication paths may be allocated for network communication with individual network subscribers and / or transmission bandwidth may be retained.
  • In an exemplary inventive method, the central entity may prioritize the available communication channels / notification services. For example, the central instance can prioritize based on the timeliness of replies of the network participants. One way of prioritizing on the basis of actuality is, for example, a network participant whose answer is particularly up-to-date, ie. H. especially in the recent past is to give a higher priority, as a network participant whose answer is a long time ago. Another exemplary criterion against which the central entity could prioritize is the reliability of the communication channels / notification services: Thus, a communication channel / notification service assigned a higher priority on a network subscriber with a permanent power supply than an identical communication channel / notification service could be assigned to one Device is running on battery or battery.
  • In one embodiment, a data processing method for managing the execution of an automated process required communication channels for communication with a driver of a vehicle and / or notification services for notifying a driver by a central authority is a notification of a driver by means of sound output with a mobile phone. In this case, a notification service is realized as a data service executed on the mobile phone. The communication channel for communication with the driver in this case is an acoustic channel, since it is indeed a sound output.
  • In a further embodiment of a data processing method for managing communication channels required for the course of an automated process for communicating with a driver of a vehicle and / or notification services for notifying a driver by a central authority, the driver is informed by means of an overlay on the operating display of a notebook computer. This can also be realized, for example, in the form of a pop-up dissolve. The notification service used thereby is executed on the notebook computer, and the communication channel in this case is a visual channel on the notebook computer, which is not limited thereto, but may include an audible output of warning sounds or a voice output.
  • In another exemplary embodiment of a data processing method for managing communication channels required for the execution of an automated process for communicating with a driver of a vehicle and / or notification services for notifying a vehicle driver by a central authority, issuing a notification of the driver by means of vibration of a smartwatch. A notification service is executed on the smartwatch, through which the central entity can cause the output of a vibration on the smartwatch. The communication channel is in this case a haptic.
  • In a further exemplary embodiment of a data processing method for managing communication channels required for the course of an automated process for communicating with a driver of a vehicle and / or notification services for notifying a vehicle driver by a central authority, notification of a driver is effected by outputting a light signal by means of the interior lighting of the vehicle. In this exemplary embodiment, the controllers that control the interior lighting perform notification services. The communication channel is here a visual channel. In an exemplary embodiment, the automated process is automated travel, and the data processing method of the invention manages the communication channels and / or messaging services required for automated travel. In this example, it is ensured by means of the data processing method according to the invention that the necessary means are available for signaling to a driver, for example, that he must take over the vehicle guidance or take over in the near future. For this purpose, a central authority in the vehicle manages the communication channels for communication with the driver of a vehicle and / or notification services for notifying the vehicle driver. About the communication channels and / or notification services is communicated with the driver and / or the driver is notified that he must take over, for example, in a certain time, the leadership of the vehicle m. This can be the case, for example, when the automated journey ends or has to be interrupted.
