Definitions
- the invention relates to a method for carrying out a functional diagnosis of at least one vehicle component of a vehicle in production and a diagnostic system for carrying out the method according to the type defined in more detail in the preamble of claim 7.
- a vehicle Before a vehicle is delivered, it is checked whether the correct software, in particular the current version, is installed on the respective computing units or control devices installed in the vehicle.
- the sensors installed in the vehicle are calibrated.
- the inspection of the vehicle can stipulate that individual functional check steps are carried out manually, partially assisted or fully automatically by a computer system.
- a corresponding computer system is typically connected by cable to a computing unit in the vehicle using a so-called onboard diagnostic connector.
- the vehicle-external computer system then controls the corresponding vehicle components to be checked or calibrated.
- DE 102009 033 806 A1 discloses a method for manufacturing and testing functionality in production.
- the method describes central management of the performance of the functional test of a vehicle or vehicle components in production by a central computing unit. It is therefore necessary to carry out different functional tests at different production and/or testing stations for different model variants.
- the relevant process steps and corresponding program code are stored on the central computing unit for the different model variants and production and/or testing stations.
- the test data generated during the test is also collected and evaluated centrally, which enables potential errors to be quickly and directly assigned to a corresponding source of error. This also makes it easier to initiate countermeasures to correct a corresponding error.
- the maintenance of motor vehicle control units via mobile radio is known from DE 102013 014 878 B3.
- the method provides for the establishment of a mobile radio-based communication connection between a vehicle-external computing device and a vehicle-internal control device, with device data being exchanged between the computing device and the control device via the communication connection.
- the device data is configuration data for the control device, error messages from the control device and/or status messages from the control device.
- the vehicle-external computing device acts as a central administrative body for carrying out vehicle diagnostics. In this way, the computing device can transmit a command to a respective control device, which causes a self-test to be carried out according to a predefined routine implemented in the respective control unit.
- DE 102012 110 623 A1 discloses a measuring device for carrying out measuring and testing tasks in predeterminable processes.
- the measuring device is set up to read a file that contains a process description.
- the measuring device converts the process description into a program flow routine and executes it.
- the file may have been created with a Business Process Model and Notation editor.
- a method and a manufacturing system for manufacturing a motor vehicle is known from DE 102018 203 067 A1.
- the method provides for the detection of a voice input by a vehicle-internal control device and the assignment of a corresponding meaning.
- a data record corresponding to the meaning is then transmitted to the test device for evaluation via an interface between the control device and the vehicle-external test device.
- the present invention is based on the object of specifying an improved method for carrying out a functional diagnosis of at least one vehicle component of a vehicle in production, which ensures efficient and reliable implementation of the functional diagnosis.
- this object is achieved by a method for carrying out a functional diagnosis with the features of claim 1 and a corresponding diagnostic system used for this purpose with the features of claim 7.
- Advantageous refinements and further developments result from the requirements that depend on this.
- a method according to the invention for carrying out a functional diagnosis of at least one vehicle component of a vehicle in production differs from a generic method in that it has the following method steps:
- - Generating a diagnostic execution protocol by means of a first vehicle-external computing unit, the diagnostic execution protocol comprising machine-readable instructions for carrying out an at least partially automated functional diagnosis of vehicle components by a vehicle-internal computing unit; - Transferring the diagnostic execution protocol to the vehicle-internal computing unit of the vehicle being manufactured;
- the method according to the invention provides for the computing unit executing the functional diagnosis to be relocated to the vehicle itself.
- the vehicle carries out the functional diagnosis independently, which enables the functional diagnosis to be carried out particularly efficiently.
- fewer computing-intensive resources are required to carry out the functional diagnosis, since a single central computing system no longer has to control a large number of control devices at the same time to carry out the functional diagnosis of a large number of vehicles.
- the first computing unit external to the vehicle can be understood as a developer system.
- the machine-readable instructions are program code that can be executed by the vehicle's internal computing unit. This enables the vehicle-internal computing unit to control the vehicle components to be checked in accordance with the diagnostic steps to be carried out. Corresponding diagnostic steps can be carried out and logged completely automatically by the vehicle's internal computing unit or manually assisted by the person supervising the production of the vehicle. For example, it may be necessary that the person has to manipulate the vehicle manually so that the functional test can be carried out completely and/or the person has to record and record the reaction caused by controlling the vehicle component. The person can then see a corresponding test result Enter the vehicle itself or via the first or second computing unit external to the vehicle.
- the second vehicle-external computing unit can be a computing system used in production. For example, it can be a central production computer or an isolated system, for example a computer system provided at a production and/or testing station.
- the diagnostic execution protocol can include corresponding instructions for responding to errors, such as re-performing individual calibration or testing steps and/or post-processing steps, which are then implemented accordingly by the vehicle-internal computing unit.
- the corresponding instructions can be part of a common diagnostic procedure or, in addition, can be designed as a “standard answer” to respond to typical errors.
- Individual diagnostic execution protocols can also be generated for these standard answers and transferred to the vehicle's internal computing unit for storage, which are then executed as required.
- the instructions included in the diagnostic execution protocol can be executed sequentially and/or in parallel by the vehicle-internal computing unit.
- the diagnosis to be carried out is divided into a “preparation”, a “main part” and a “post-processing”.
- preparation can be: setting up a communication connection between computing units inside and/or outside the vehicle, carrying out authentication and/or authorization, setting up a so-called “session” and the like.
- the main part can be: controlling actuators, reading sensor data, reading out an error memory of a control unit, adjusting calibration parameters and the like.
- post-processing can be: ending a communication connection, writing result data, publishing the result data to a system external to the vehicle, resetting control unit states and the like.
- the diagnostic execution protocol is generated on the first computing unit external to the vehicle using a graphic specification language
- the diagnostic execution protocol being a flowchart from the vehicle-internal Computing unit includes diagnostic steps to be carried out, wherein the vehicle-external computing unit reads machine-readable instructions corresponding to the diagnostic steps from a vehicle-external database and integrates them into the diagnostic execution protocol.
- the process for generating applicable program code on the vehicle-internal computing unit is designed efficiently, from the pure idea, through the exact procedure of how a process step is to be carried out, to the generation of program code, up to the final implementation and application by the vehicle-internal computing unit. In particular, this allows media disruptions to be avoided, which significantly reduces the risk of errors.
- the process steps to be carried out in the functional diagnosis are graphically formulated in a user-friendly and easy-to-understand manner using the graphical specification language and are converted directly into machine-readable instructions by automatically reading the instructions suitable for the respective diagnostic steps from the vehicle-external database by the first vehicle-external computing unit.
- the vehicle-external database can be understood as a so-called code repository. Machine-readable instructions required for all possible machine-executable steps are implemented in the code repository. This means that manual programming effort is no longer required to integrate the machine-readable instructions required to carry out a specific functional diagnosis into the vehicle's internal computing unit.
- a programmer can write new machine-readable instructions into the vehicle-external database, i.e. the code repository, which also allows functional diagnostics to be carried out reliably using the new components. If bugs occur, existing machine-readable instructions in the vehicle-external database can be updated and revised.
- the diagnostic execution protocol thus describes a generic term for both the purely mental sequence of the test steps to be carried out in a functional diagnosis and the program code used for this purpose to control vehicle components by the vehicle-internal computing unit.
- the use of a graphical specification language leads in particular to a reduction in manual errors by the person supervising production.
- the person can view the test steps to be carried out graphically displayed on any display device, for example on a tablet used in production and/or augmented reality glasses, and thereby understand the work steps involved in an easy-to-understand manner.
- the diagnostic execution protocol can therefore be interpreted in an easily understandable manner by both the person and a machine.
- BPMN Business Process Model and Notation
- a further advantageous embodiment of the method further provides that the vehicle-internal computing unit is connected by wire and/or wirelessly to a common communication network with a vehicle-external computing unit and the vehicle-internal computing unit exchanges information with the vehicle-external computing unit indirectly via a communication server.
- the vehicle-external computing unit can be the first or the second vehicle-external computing unit.
- the vehicle-internal computing unit can be connected to the corresponding vehicle-external computing unit by cable via an Ethernet cable or an onboard diagnostic cable.
- WLAN and/or mobile communications are preferably used for wireless communication, in particular using 5G or future mobile communications standards. In particular, the use of WLAN and/or mobile communications with at least the 5G mobile communications standard allows data transmission at comparatively high data transmission rates.
- the vehicle-external computing unit can be a tablet or desktop computer used by the person supervising production, which is connected by wire or wirelessly to the vehicle-internal computing unit in a communicative manner.
- the person's tablet can set up an ad hoc WLAN into which the vehicle's internal computing unit connects.
- the person can, for example, generate a new diagnostic execution protocol on the tablet using the graphical specification language and transmit this directly to the vehicle's internal computing unit for use.
- This enables a particularly quick reaction and adjustment of the process steps to be carried out to carry out the functional diagnosis.
- Such a procedure can also be used in the development of the machine-readable instructions to be stored in the vehicle-external database from the corresponding process steps integrated in the flowchart.
- a vehicle-external database can be integrated into the tablet integrated at the production and/or testing station. After the person has generated a corresponding flowchart, the tablet can integrate corresponding machine-readable instructions into the diagnostic execution protocol. There is a risk that outdated machine-readable instructions will be read from the tablet-internal, vehicle-external database.
- corresponding distributed vehicle-external databases can be updated with updated program code.
- a further advantageous embodiment of the method according to the invention further provides that the vehicle-internal computing unit controls a vehicle-external manipulation machine in order to carry out at least one diagnostic step and/or initiate measures if the at least one vehicle component is malfunctioning in its correct functioning.
- Corresponding machine-readable instructions for controlling the vehicle-external manipulation machine are then also integrated into the diagnostic execution protocol or into further diagnostic execution protocols.
- the integration is preferably carried out automatically depending on the process steps of the flowchart defined in the graphical specification language.
- the vehicle-external manipulation machine can be a robot provided at the production and/or testing station.
- Manipulation of the vehicle or a vehicle component can be done in a variety of ways, for example the vehicle-external manipulation machine can move the vehicle or a vehicle component, check it with the help of sensors external to the vehicle, add new components or replace, detach, or the like already integrated components. This makes it possible to rework the vehicle or vehicle components after carrying out the actual functional diagnosis.
- the method according to the invention therefore enables the vehicle-internal computing unit to be able to control vehicle-external machines used in production or testing. A central computing unit is then no longer required to control the vehicle-external manipulation machines. This also ensures increased efficiency when carrying out functional diagnostics.
- the vehicle-internal computing unit can directly control the vehicle-external manipulation machine, for example via direct communication via WLAN or indirectly via a vehicle-external computing unit such as a central factory server.
- a diagnostic system with a first vehicle-external computing unit and with a vehicle in production comprising a vehicle-internal computing unit
- the first vehicle-external computing unit and the vehicle are set up to carry out a method described above.
- the vehicle-internal computing unit is able to control and monitor all relevant vehicle components electrically or electronically. This allows time-critical diagnostic process steps to be carried out with particularly low resources and comparatively low latencies. This ensures an efficient functional diagnostic process.
- An advantageous development of the diagnostic system provides at least a second vehicle-external computing unit, the second vehicle-external computing unit being set up to receive information from the vehicle-internal computing unit to be received and/or controlled.
- the vehicle-internal computing unit can, for example, transmit results of the functional diagnostic test to the second vehicle-external computing unit, which are stored there for evaluation. Depending on the evaluated results, measures to correct errors can also be initiated by the second vehicle-external computing unit.
- the vehicle-internal computing unit can also control the second vehicle-external computing unit.
- the second vehicle-external computing unit is the control device of a vehicle-external manipulation machine.
- the diagnostic system preferably comprises a communication server, wherein the communication server is set up to exchange information between the vehicle-internal computing unit and the first vehicle-external computing unit.
- This enables central management of the vehicle-external database. This means that the engineers involved in functional diagnostic planning do not have to be physically present in the factory to develop or implement new functional diagnostic processes.
- the corresponding newly generated diagnostic execution protocols can be transmitted via the communication server to the respective production and/or testing stations in production and imported there to the respective in-vehicle computing units. In general, it is also possible that said diagnostic execution protocols are already pre-installed on the vehicle-internal computing unit before the corresponding vehicle-internal computing units are installed in the vehicle.
- Corresponding diagnostic results can be temporarily stored on the vehicle-internal computing unit and transmitted to the first and/or second vehicle-external computing unit as soon as there is a communication connection to the first and/or second vehicle-external computing unit.

- FIG. 3 shows a schematic representation of the infrastructure of a vehicle manufacturer used for the production and development of vehicles according to a second embodiment
- Fig. 4 is a schematic representation of a production line
- Fig. 5 is a schematic representation of distributed production.
- the core idea of the method according to the invention for carrying out a vehicle diagnosis of at least one vehicle component of a vehicle 1 that is in production is the independent implementation of the functional diagnosis by a vehicle-internal computing unit RI.
- the complete sequence of development of the process steps to be carried out in the functional diagnosis up to the generation of program code, implementation of the program code in the vehicle-internal computing unit RI and execution of this is designed by using a graphic specification language, preferably Business Process Model and Notation (BPMN).
- BPMN Business Process Model and Notation
- An engineer 5 creates a flowchart of the diagnostic steps to be carried out by the vehicle-internal computing unit RI on a first vehicle-external computing unit RE_1 using the graphic specification language.
- a diagnostic execution log 2 is created from this.
- the diagnostic execution protocol 2 can be formulated in the graphical specification language and then converted into a metalanguage such as XML.
- the first vehicle-external computing unit RE_1 reads machine-readable instructions corresponding to the diagnostic steps from a vehicle-external database 3, also referred to as a code repository, and integrates these into the diagnostic execution protocol 2. This is done in method step 101.
- the vehicle-external database 3 can be stored on the first vehicle-external computing unit RE_1 are held and/or on a data storage in a network, for example on a central server.
- the diagnostic protocol 2 is transmitted via a communication server RKOM, for example a proxy server, to a factory 6 of the vehicle manufacturer in which production is located. In the factory 6, the diagnostic execution protocol 2 is distributed to the corresponding in-vehicle computing unit RI of the vehicle 1 to be checked.
- the diagnostic execution protocol 2 or the machine-readable instructions contained therein are executed by the vehicle-internal computing unit RI, whereby the vehicle-internal computing unit RI at least controls a vehicle component to be checked and the corresponding response behavior is recorded automatically or manually assisted by a person supervising the production of the vehicle 1. If the functional diagnosis is successful, as indicated by a checkmark in FIG. 1, the vehicle 1 can be released for the next production step or for handover to the dealer. However, if the functional diagnosis is faulty, as indicated by a flash in Figure 1, further measures must be taken. The further measures can also be described by instructions integrated into the diagnostic execution protocol 2 and can be executed or initiated by the vehicle-internal computing unit RI.
- Figures 2 and 3 serve once again to illustrate the vehicle manufacturer's infrastructure used for the production and development of vehicles.
- FIG 2 several first vehicle-external computing units RE_1 are shown.
- Each of the first vehicle-external computing units RE_1 includes its own vehicle-external database 3.
- the first vehicle-external computing units RE_1 can be, for example, the development PC of an engineer 5.
- a diagnostic execution protocol 2 can be generated via such a PC and transmitted to a respective factory 6 via the communication server RKOM.
- a communication relay 7, for example a WLAN router or a 5G modem can be provided, via which the communication server RKOM is connected to a common communication network with the vehicle-internal computing unit RI.
- a corresponding transmission of the diagnostic execution protocol 2 to the vehicle-internal computing unit RI is shown in Figure 2 by a dotted line.
- the vehicle-internal computing unit RI can also control a vehicle-external manipulation machine 4, for example a manipulation robot. So can the manipulation robot moves parts of the vehicle or manipulates them in some other way.
- vehicle-external manipulation machine 4 can also include one or more sensors for checking the condition of the vehicle 1 or vehicle components. Such a sensor can be, for example, a camera, a conductivity sensor, a temperature sensor, a force sensor, an ultrasonic sensor or the like.
- a control device of the vehicle-external manipulation machine 4 can be referred to as a second vehicle-external computing unit RE_2.
- vehicle-external computing units RE_2 can also be provided, such as a central factory server RE_2_Zentral.
- Results of a respective functional diagnosis generated by the vehicle-internal computing units RI of vehicles 1 to be manufactured and/or checked can be stored and evaluated on the central factory server RE_2_Zentral.
- the vehicle-internal computing unit RI or the central factory server RE_2_Zentral can control corresponding vehicle-external manipulation machines 4 in order to automatically initiate countermeasures to correct the error in the event of an error. People can also be notified who can initiate manual troubleshooting.
- a first vehicle-external computing unit RE_1 can also communicate directly with the vehicle-internal computing unit RI.
- a tablet computer RE_2_Tab is shown as an example, which can be used by a person supervising the production of the vehicle 1 to interact with the vehicle-internal computing unit RI. This allows particularly short communication paths between the first vehicle-external computing unit RE_1 and the vehicle-internal computing unit RI.
- Figure 3 shows a representation similar to Figure 2.
- a central vehicle-external database 3.1 and, if necessary, a central server RE_1_Zentral, indicated by a dashed line, are integrated into the computer network of the first vehicle-external computing units RE_1.
- Developers can maintain machine-readable instructions, i.e. code modules, stored in the central vehicle-external database 3.1.
- the corresponding first vehicle-external computing units RE_1 for example developer PCs, can then update their respective vehicle-external database 3 by reading out the central vehicle-external database 3.1.
- Some of the developer PCs do not have an integrated one vehicle-external database 3 and are dependent on a direct connection to the central vehicle-external database 3.1.
- the entire process can also be managed by the central server RE_1_Zentral.
- the results of the functional diagnoses transmitted by the vehicle-internal computing units RI of the individual vehicles 1 can be stored and evaluated. This enables central analysis of data from production. In this way, the advantages of decentralized control of the performance of the functional diagnosis and the central evaluation of the corresponding results can be combined.
- FIG. 4 shows the manufacturing and/or testing stations 9 arranged in series on a production line 8. Individual manufacturing steps of a vehicle 1 or a vehicle component can be carried out at a manufacturing and/or testing station 9 and/or a vehicle 1 or vehicle components be subjected to a functional diagnosis.
- Each manufacturing and/or testing station 9 can have its own second, vehicle-external computing unit RE_2, for example a central computer, which controls the machines used at the respective manufacturing and/or testing station 9.
- Each such machine for example a vehicle-external manipulation machine 4
