Definitions
- Vehicle component for providing at least one service in one
- the present invention relates to a vehicle component and a method for providing at least one service in a vehicle.
- SOA service-oriented architecture
- SD Service Discovery
- AUTOSAR AUTomotive Open System ARchitecture
- SOME / IP Scalable Service-Oriented Middleware over IP
- the services are typically coordinated by messages (hereinafter also referred to as service identification messages) that are sent as multicast.
- service identification messages This means that the messages have to be evaluated by most control units in the network, although they may neither offer nor require the corresponding service. That logic is traditionally a pure software solution and therefore creates a high load on the microcontrollers.
- a vehicle component for providing at least one service in a vehicle
- the vehicle component can have the following parts: at least one (in particular electronic) processing unit, such as a processor, for performing data processing in order to (via data processing) the at least perform a service, preferably so that this service can be provided by the vehicle component for other vehicle components of the vehicle, which can thus use the service for their own and / or higher-level services, preferably in accordance with the SOA and / or SOME / IP (the latter in particular as a possibility to integrate the SOA into the control units of the vehicle), at least one (in particular electrical and / or electronic) data interface for connection to at least one Data transmission network of the vehicle in order to receive and / or send data for data processing during the execution of the service, and / or to (at least) one service identification message for service coordination (in particular coordination in the
- an (in particular electronic) pre-filter unit for performing a relevance check of the (at least one) received service identification message, in particular based on a service specification (the vehicle component), in order to display the service identification message as a function of the relevance check forward the processing unit.
- the prefilter unit can thus be connected upstream of the processing unit in order to check the relevance of the service identification message for the processing unit before the processing unit has to evaluate the service identification message.
- the prefilter unit can comprise at least one integrated circuit, or it can be integrated into a microcontroller. Furthermore, the prefilter unit can carry out the relevance check without the support of the processing unit - and thus in particular independently of the processing unit.
- the vehicle component can be designed, for example, as a control device or a sensor or an actuator of the vehicle in order to provide one or more vehicle functions.
- the vehicle is z. B. a passenger vehicle or a truck, which optionally includes at least one driver assistant and / or an autonomous driving function and / or a radar sensor for monitoring the surroundings of the vehicle and / or an electronic steering system and / or the like, each of which is controlled by the at least one Service can be operated.
- the service can be exemplified as a radar detection or as a Be carried out steering wheel angle determination or the like.
- SOA ie a service-oriented architecture, these services can be encapsulated and coordinated.
- the services that are offered by individual vehicle components can be combined to form higher-level services (such as the aforementioned vehicle functions, e.g. a driver assistance function).
- the dynamic integration of services is also possible.
- a service is therefore dynamically linked, ie when an application is created (as in the case of the aforementioned vehicle functions) that uses a service, the service does not initially need to be available. It is only localized and integrated during execution. It is therefore necessary to coordinate the services using the service identification messages.
- the vehicle components, which services are available are in communication with one another.
- the transmission of the service identification messages in this data transmission network can take place as a multicast, so that all of the vehicle components connected to the data transmission network can receive the transmitted service identification messages and, if necessary, an evaluation of the received messages is always provided. Since this frequent evaluation - particularly in the case of vehicle components - can lead to massive problems with regard to the utilization of the vehicle component, the prefilter unit is provided according to the invention. This makes it possible to carry out a relevance check of the service identification message without using the processing unit, and thus to contribute to the coordination of the services.
- the processing unit can e.g. B. be designed as a data processing device such as a processor of an electronic assembly of the vehicle component.
- the prefilter unit can also be an electronic component (ie an electronic component such as an arrangement of electronic components or a separate integrated circuit or a separate part of a microcontroller) of the electronic arrangement of the vehicle component, and be designed for data processing.
- the electronics arrangement can have at least one memory with at least one computer program which includes instructions to at the execution by the processing unit and / or the prefilter unit to execute the method according to the invention.
- the data transmission network is designed to carry out the data transmission by means of SOME / IP, so that the data interface can also be designed as a SOME / IP interface.
- the data interface can thus be used to enable the vehicle components to be used within an AUTOSAR-compliant architecture.
- an SOA Service-Oriented Architecture
- Various control units, sensors and actuators in the vehicle are networked with one another via the SOA structure.
- the participating electronic vehicle components in particular the control units, can support the corresponding interfaces and protocols.
- the vehicle component according to the invention can also be designed as such a participating electronic vehicle component, in particular as a control device, which has the data interface to the data transmission network as the interface.
- the vehicle component according to the invention can thus form one of the clients in the SOA network.
- So-called find or offer services are used to find or offer services that are stored distributed in the SOA network by the clients or by a server.
- multicast mode ie messages are transmitted from one point to a group of participants (multipoint connection).
- service identification messages are sent in the data transmission network, which are received by several clients, in particular all clients.
- These messages include a service request, which for this purpose includes information about the requested service, such as a service ID.
- a service request which for this purpose includes information about the requested service, such as a service ID.
- the corresponding service requests and also service offers are also evaluated by participants (vehicle components) of the vehicle, although they do not offer or require the corresponding service. this in turn brings with it a disadvantageous high load on the microcontroller.
- the corresponding request / offer messages can advantageously be filtered, for example filtered using data in the header and / or in so-called service entries, thus preventing unnecessary further processing.
- the processing unit is designed to execute the at least one service as part of a service offering of the vehicle component, and / or that the prefilter unit is designed to carry out the relevance check by comparing the service identification message with the service offering in order to convert the service identification message into To forward depending on the comparison to the processing unit.
- the service identification message is used to search for a service. It is then a find service, so that the corresponding service identification message can also be referred to as a service request message.
- the prefilter unit can thus be understood as an SD filter for the find service.
- SD filters for the other services are created according to the same structure.
- the comparison can then be expanded by the prefilter unit to the effect that the service identification message (then in the form of a service offer message) is compared with a service request.
- Both the service request and the service offer can be stored in a service specification (for example in the form of lookup tables).
- the data interface is designed to receive the service identification message in the form of a service request message for requesting a desired service
- the prefilter unit is designed to forward the service identification message to the processing unit depending on the comparison when the requested service Service in which the service offer is available. This means that another SOA-capable vehicle component can be reliably notified when the desired service is available. in order to provide a higher-level service in cooperation with these vehicle components.
- the prefilter unit is designed to forward the service identification message to the processing unit only as a function of the comparison when the requested service is available in the service offering, and thus the at least one service provided by the vehicle component is equivalent to. A significant reduction in the workload for the processing unit can thus take place.
- the prefilter unit and the processing unit are designed as separate electronic components of an electronic arrangement of the vehicle component. This hardware separation makes it possible to reliably reduce the load on the processing unit.
- the prefilter unit and the processing unit are integrated together on a printed circuit board of the vehicle component, in particular in a common microcontroller.
- the electronics assembly can thus be provided as a compact and easy-to-assemble electronics assembly for the vehicle component.
- the processing unit is designed in the form of a processor and / or the prefilter unit is designed in the form of a circuit designed specifically for the relevance check and forwarding.
- the prefilter unit can thus reliably carry out the prefiltering of the service identification messages.
- the data transmission network is designed as a network for an SOA. It is also conceivable for the data interface to be designed as a service-oriented interface in order to Establish a connection to the data transmission network.
- the data interface can, for example, be designed as an Ethernet interface.
- the data transmission network is designed as an Ethernet. That is to say, the data interface can be designed to establish the connection to the data transmission network in the form of Ethernet, so that the data interface can be designed as an Ethernet interface.
- the data transmission network is designed as a CAN bus system (Controller Area Network bus system). That is, the data interface can be designed to establish the connection to the data transmission network in the form of the CAN bus system, so that the data interface can be designed as a CAN bus interface.
- CAN bus system Controller Area Network bus system
- the prefilter unit is designed to evaluate a data structure corresponding to an SOA of the vehicle in the service identification message in order to carry out the relevance check.
- the data structure specifies, for example, the position at which the service-related field is located, which contains information about a desired service. The comparison for the relevance check can therefore take place on the basis of this information.
- the vehicle component and / or the processing unit is designed to provide the service as a service within an SOA of the vehicle.
- the vehicle component can thus be SOA-compatible in order to enable flexible and dynamic provision of services in the vehicle.
- the prefilter unit is an ASIC (application-specific integrated circuit) or an FPGA (field programmable gate array) or a SOA adapter is designed for the vehicle component.
- the processing unit for example in the form of a processor, can be reliably relieved.
- the invention also relates to a method for providing at least one service in a vehicle. It is provided that the following steps are carried out, preferably one after the other or in any order, whereby individual and / or all steps can also be repeated:
- the method according to the invention thus has the same advantages as have been described in detail with reference to a vehicle component according to the invention.
- the vehicle component used in the method according to the invention can be designed as a vehicle component according to the invention.
- performing the relevance check includes the following steps: Carrying out a data extraction of the data in the received service identification message, preferably depending on an SOA data structure, preferably according to SOME / IP, particularly preferably from a SOME / IP header according to AUTOSAR,
- the service specification can include information about a service offer and / or a service request of the vehicle component
- the relevant messages can be reliably separated from the non-relevant messages in order to filter out the non-relevant messages.
- the data can be extracted according to a SOME / IP protocol.
- the type of message can be checked in such a way that it is checked that the service identification message is actually one, for example a SOME / IP SD (Service Discovery) message.
- SOME / IP-SD Service Discovery
- SOME / IP-SD provides two mechanisms that allow services to be found dynamically.
- An offer service enables the server to offer all of the services it offers in the network.
- FIG. 1 shows a schematic representation of two vehicle components according to the invention in a vehicle
- FIG. 3 shows a further schematic representation of a vehicle component according to the invention
- FIG. 1 shows two examples and FIGS. 2 to 4 each show an example of a vehicle component 10 according to the invention for providing at least one service in a vehicle 1.
- the vehicle components 10 shown in FIG. 1 can offer different services and therefore also be designed differently.
- the Vehicle components 10 according to FIGS. 1 to 4 have at least one processing unit 20 for carrying out data processing in order to carry out the at least one provided service.
- a data interface 30 can be provided for connection to a data transmission network 2 of the vehicle 1, in order to receive and / or send data for data processing during the execution of the service, and to receive a service identification message 210 for service coordination in the data transmission network 2.
- a special feature according to the invention is the use of a prefilter unit 40 for the vehicle components. This is used to carry out a relevance check 110 of the received service identification message 210 in order to forward the service identification message 210 to the processing unit 20 as a function of the relevance check 110. This makes it possible to relieve the processing unit 20, which otherwise would have to evaluate a possibly very large number of service identification messages 210 itself, even if these are not relevant for the service provided.
- the processing unit 20 can be designed to execute the at least one service as part of a service offering 220 of the vehicle component 10, the prefilter unit 40 being able to carry out the relevance check 110 via a comparison 150 of the service identification message 210 with the service offering 220 in order to identify the service identification message 210 to be forwarded to the processing unit 20 as a function of the comparison 150.
- the data interface 30 can be designed to receive the service identification message 210 in the form of a service request message 210 for requesting a desired service, the prefilter unit 40 being designed to forward the service identification message 210 to the processing unit 20 as a function of the comparison 150, if the requested service is available in the service offering 220.
- the service identification message 210 can only then be sent to the processing unit 20 as a function of the comparison 150 are forwarded when the requested service is available in the service offering 220 and thus corresponds to the at least one service provided by the vehicle component 10.
- the prefilter unit 40 and the processing unit 20 can be designed as separate electronic components of an electronic assembly 60 of the vehicle component 10. Nevertheless, according to FIG. 4, the prefilter unit 40 and the processing unit 20 can be arranged together on a printed circuit board 62 of the vehicle component 10. In the example shown in FIGS. 3 and 4, the prefilter unit 40 and the processing unit 20 are physically separated, arranged at a distance, and possibly only electrically connected by conductor tracks. Alternatively, it is provided according to FIG. 2 that the prefilter unit 40 and the processing unit 20 are integrated in a common microcontroller 61. Nevertheless, these are also separate components that can each carry out the data processing independently. It is particularly advantageous if the prefilter unit 40, in contrast to the processing unit 20, is designed in the form of a circuit designed specifically for the relevance check 110 and the forwarding.
- Carrying out the relevance check 110 can include the following steps:
- the data in the SOME / IP header are evaluated, which define whether the received message is generally a service identification message 210 (SOME / IP-SD message) or not. This can be used as a first indicator to filter for “SD Messages”.
- the “Service Entries” can be evaluated during the extraction 140 (e.g. Offer, Find, ).
- the service-related field 230 can include, for example, the “Find Service Entry” field, which in turn can consist of several fields. These can define the service you are looking for. These fields can be evaluated by the pre-filter unit 40 at the hardware level.
- the fields “Type” and “Service ID” of the service-related field 230 can then be compared with the supported services of the vehicle component 10 in the service specification 215. With these two fields, the majority of the irrelevant inquiries are filtered out. Only in the event of a match can the service identification message 210 be passed on to the downstream evaluation logics - that is to say the processing unit 20.
- other relevant fields from the "Find Service Entry” can also be taken into account in the comparison. These are, for example, Instance ID, Major Version and Minor Version. Further SD filters can be created for the other services (offer, ...) according to the same structure.
