Method for performing analysis, identification and / or troubleshooting and a communication system for performing the method

Description

[0001] The invention relates to a method for performing an analysis, identification and / or error correction according to claim 1. Furthermore, the invention relates to a communication system for performing the method according to claim 16.

[0002] The operation, control and activation of vehicles and their components is increasingly processor-supported, i.e. electronic. Purely mechanically functioning components are increasingly being replaced by components that can be controlled exclusively electronically and are equipped with corresponding technology or motors. Even if this development brings with it many advantages, the analysis of malfunctions, faults and defects, their identification and troubleshooting is becoming increasingly difficult or even impossible for vehicle drivers, who normally do not have the corresponding specialist knowledge. Whereas in the past malfunctions and defects could be rectified with a screwdriver, open-end wrench or voltage tester, today special analysis devices are required which are linked directly to a readout unit on the vehicle or the defective component.Since the components are not equipped with such special equipment in the vast majority of cases, the analysis or identification of malfunctions, as well as maintenance, is only possible in specialised workshops or by mobile service personnel. This poses a particular problem for the operation of trucks, delivery vehicles, construction vehicles or other vehicles used for business purposes. Since problems, errors or defects in vehicles or trucks or the like, and especially in components on these vehicles, cannot in the vast majority of cases be analyzed and rectified on-site by the vehicle drivers, the vehicle must be taken to a service workshop. However, this is associated with increased expenditure or loss of time, which can lead to disruptions in complex supply chains. Analysis and error rectification by a mobile service representative also leads to similar time losses.If a component of a truck or similar vehicle malfunctions, it can lead to the entire vehicle being taken out of service. This can not only result in financial loss but also pose a risk to the driver and third parties. If, for example, a truck's tail lift can no longer be opened or closed due to a defect, this has a significant impact on the fulfillment of the delivery order. In particular, if a tail lift or tailgate can no longer be closed, the truck must be repaired on-site by a mobile service technician. This can result in a road or loading ramp being blocked for several hours. In addition, the supply chain is also interrupted for an extended period.

[0003] The document "Connected Vehicle Sensor Platform" (Coen Lauwerijssen, 2M Engineering) discloses a bidirectional communication platform for the exchange of vehicle-related data between a vehicle and a central server via a mobile phone.

[0004] The present invention is based on the object of creating a method for carrying out an analysis, identification and / or error correction as well as a communication system for carrying out the method, with which the analysis, identification and / or error correction can be carried out in a particularly simple and time-efficient manner.

[0005] A solution to this problem is described by the measures of claim 1. Accordingly, it is provided that in order to carry out an analysis, identification and / or troubleshooting, preferably a remote maintenance, of a tail lift of a truck, a data connection is established between at least one mobile communication means and a control unit of the tail lift.

[0006] The mobile communication device can be a mobile phone, smartphone, tablet, or similar. This communication device is carried by an operator or driver of the vehicle or truck. However, this mobile communication device can also be operated by a service employee. The connection between the communication device and the control unit of the component (tailgate) can be a near-field connection. Since the driver is in the immediate vicinity of the vehicle component, the connection can be made via radio or Bluetooth ®, for example. Identification data for identifying the mobile communication device and the vehicle components or vehicle can initially be exchanged between the communication device and the control unit of the component. This can also include verification data, operating parameters, and, if applicable, information data regarding an error that has occurred.

[0007] The data transmitted from the component's control unit to the mobile communication device or read by the mobile communication device is referred to as outgoing data. In a subsequent process step, this outgoing data is transmitted to an electronic data processing network via another connection, which may be a far-field connection. This electronic data processing network may be a server or a cloud located far from the vehicle. This electronic data processing network can be centrally or decentrally located, such that the mobile communication device can establish a far-field connection with this network regardless of location.

[0008] In a further step, depending on the outgoing data, data can be transmitted directly back from the data processing network to the mobile communication means. This data transmitted from the data processing network to the mobile communication means is referred to as incoming data. Alternatively, it is conceivable that the outgoing data is first transmitted from the data processing network to a network application and that incoming data is then transmitted from this network application to the mobile communication means. This incoming data can contain information relating to the analysis, identification and / or troubleshooting as well as remote maintenance of the defective component. Through this exchange of data between the control unit of the vehicle components and the mobile communication means as well as between the communication means and the data processing network orThe network application allows for analysis, identification, troubleshooting and, if necessary, remote maintenance in a simple and time-efficient manner.

[0009] Preferably, it is further provided that the exchange of data between the component and the at least one mobile communication means is initialized by the operator or the vehicle driver. Alternatively, it is conceivable that in the event of a malfunction of the component, the data exchange between the component and the at least one mobile communication means is initialized automatically. As soon as the operator thus detects a malfunction, for example of the tail lift, the exchange of data or outgoing data between the control unit of the tail lift and the smartphone can be initiated by correspondingly actuating or operating the mobile communication means. Likewise, it is conceivable that the malfunction is already detected by the control unit of the tail lift and a corresponding signal is transmitted to the mobile communication means.The driver then immediately receives information about the malfunction and, if necessary, what further steps need to be taken to rectify the malfunction.

[0010] A further embodiment of the present invention can provide that, depending on the identification data, verification data, operating parameters, and / or error information data, a further exchange of data takes place, in particular is initiated, between the data processing network and the at least one network application and / or a fleet manager of multiple vehicles. The identification data can be an identification number of the component and / or an identification number of the mobile communication device or the vehicle driver. The exchange of this identification data can lead to a further exchange of verification data, which must be confirmed by the operator or the control unit in order to authenticate the operator. The operating parameters can be all properties, key figures, or values ​​related to the operation of the component.A large amount of error information data can already be stored on the control unit, allowing a clear assignment of an error to a code. By reading this error information data, a service technician can immediately determine what caused a defect or what the damage consists of. The network application could, for example, be a program that a service partner responsible for operating the vehicle can use to access the mobile communication device or the control unit via the data processing network. This service partner can be located centrally or decentrally at almost any location and connect to the network or communication device via a remote data connection. The fleet manager organizes the timetables or delivery plans for a large number of vehicles belonging to the same fleet.

[0011] According to the invention, it can be provided that the fleet manager and / or the service partner connects to the data processing network using an identifier to be assigned. For example, it may be necessary for the fleet manager and / or the service partner to first register with a provider, operator, or manufacturer of the vehicle or component in order to exchange data with the data processing network and / or the mobile communication means in order to be able to access the data processing network. This offers the option of transmitting outgoing data from the mobile communication means to the data processing network, and various service partners or fleet managers can access this data in order to offer their service to the vehicle driver if necessary. This enables very time-efficient analysis, identification, troubleshooting, or troubleshooting, regardless of location.Maintenance of the vehicle or component must be ensured and / or offered.

[0012] In addition, it can be provided that, depending on the identification data, verification data, operating parameters and / or error information data, direct voice and / or video communication is established between the at least one network application and the mobile communication means. If, for example, the identification data or the verification data or the operating parameters and / or the error information data indicate that a direct conversation or video communication between a service employee of the network application and the vehicle driver will lead to rapid processing or error rectification, the direct connection can be established via the mobile communication means. This can be done via a conventional telephone connection. Since the outgoing data from the control unit has already been passed on to the network application, this or that application can...The service technician will provide the operator with specific instructions on how to resolve the problem. If necessary, this can also be done in combination with a video connection.

[0013] In particular, it is conceivable that, depending on the identification data, verification data, operating parameters, and / or error information data, a data exchange is established via the mobile communication means between the at least one network application and / or the fleet manager and the control unit of the at least one component. Some functions of the vehicle component may require the input of specific codes or commands. For example, it is conceivable that a specific code is transmitted to the control unit to initiate error analysis or emergency operation. According to the invention, this can be done directly via the network application or the fleet manager. A far-field connection is established between the network application and the mobile communication means, or a connection is established between the fleet manager, the data processing network, and the mobile communication means.The mobile communication device then transmits the data as incoming data to the control unit of the component.

[0014] Preferably, it is provided that, depending on the identification data, verification data, operating parameters and / or error information data, the network application initiates further measures, such as ordering and delivery of spare parts, coordination of a service order, reprogramming of the component software, updating of the component software, remote control of at least some functions, in particular functions blocked for the operator, in particular GEO-Fencing. If the outgoing data indicates that a defective part of the component needs to be replaced, the network application can be used to directly order a replacement part and have it delivered to the vehicle location. If necessary, a service employee can be simultaneously navigated to the vehicle location to install this component. Likewise, a software update or any necessary reprogramming of the component's software can be performed via the network application. If, for example, some functions of the component are not enabled for the operator, these functions can be enabled for manual operation by the driver, at least temporarily, to correct and / or analyze the error.

[0015] Preferably, it is further conceivable that, depending on the identification data, the verification data, the operating parameters, and / or the error information data, the fleet manager orders a replacement vehicle for the vehicle that transmitted the data or adjusts a delivery plan for goods transported by the vehicle that transmitted the data. If the outgoing data indicates that the vehicle cannot continue its journey, at least in the short term, the fleet manager sends an appropriate replacement vehicle to the location of the defective vehicle. Delivery plans and supply chains can also be adjusted so that no delays occur.

[0016] Furthermore, it is conceivable that a proprietary protocol, particularly radio, Wi-Fi, or Bluetooth®, could be used for data exchange in the near field, and protocols for far-field communication, such as radio, Wi-Fi, 5G, or IEEE802.1, could be used in the far field. Data exchange is encrypted. This ensures secure data exchange both in the near field and in the far field.

[0017] A further advantageous embodiment of the present invention can provide that a connection, in particular free of charge, from a App-Store downloadable application software (Android, iOS app) is loaded or put into operation. For data exchange with the control unit and the data processing network, the fleet manager, and / or the network application, the corresponding application software or App If necessary, the driver can download the app to their mobile communication device. After appropriate authentication and validation, the aforementioned connections can be established.

[0018] In addition, the incoming data may include error information, control commands, operating instructions, and / or troubleshooting suggestions. This provides the vehicle driver with direct instructions for correcting the component's fault.

[0019] A further essential measure of the invention may provide that for a Pairing, This means that for the connection between the component and the at least one mobile communication device, a code, in particular a key combination, is entered into a control unit of the component, with the entered code being checked for validity by the control unit of the component. This ensures that not every mobile communication device can establish a connection to the vehicle or the component. This prevents, in particular, misuse of this method. Only those who have knowledge of this code or the key combination can establish the secure connection between the mobile communication device and the component.

[0020] Furthermore, it is conceivable that the operating unit or the control unit, in the case of a positive validity check of the code, is switched via a protocol, preferably via a proprietary CAN bus protocol, which activates at least one mobile communication means, in particular into a mode for carrying out an analysis, identification and / or error correction. Pairing The integration of the mobile communication device and the control unit using a key code eliminates previous disadvantages. Previous solutions were difficult for the operator to reach or exposed to weather conditions, resulting in frequent failures. Pairing However, since it is essential for establishing the connection between the mobile communication means and the component, the reliability of the entire system can be improved by the described method.

[0021] In particular, the invention provides that in the event of a malfunction and / or a defect in the component and / or a sensor system of the component, emergency operation of the at least one component is started, in particular by an operator via an operating unit of the component or via the mobile communication means, wherein this emergency operation provides the functions required to control the component. In normal operation, i.e. in fault-free operation, the functions released to the vehicle driver are limited to the essential control commands. Further commands for emergency operation are not enabled in normal operation. However, this activation can be enabled via the communication means in the event of a malfunction. This allows corresponding release codes to be issued either by the operator themselves or by the network application. Using the emergency functions, the tail lift can at least be closed orbe opened. It is also intended that when emergency operation is activated via the mobile communication device, an acoustic and / or visual signal is generated, which informs the operator of the malfunction or defect in the components or sensors, as well as the limited functionality of the component and, in particular, the associated hazards. This is particularly important in the case where emergency operation is initiated by external control or remote maintenance from the network application.

[0022] Finally, it is conceivable that after actuation of an emergency operation signaling device, preferably an emergency operation button or knob, near-field communication, in particular a Bluetooth® connection, is established between the component's control unit and the mobile communication device, and the connection to the component's control system is established via a CAN bus. Further control of the component can then be carried out either directly by the operator via the communication device or remotely by the network application or the fleet manager.

[0023] A communication system for carrying out the method is described by the features of claim 17. Accordingly, it is provided that the communication system is designed to carry out a method for carrying out an analysis, identification and / or troubleshooting, preferably a remote maintenance, of at least one component, in particular a tail lift of a vehicle, preferably a truck, according to claim 1. For this purpose, the system has at least one mobile communication means and a control unit of the at least one component as well as a data processing network and / or a network application.

[0024] A preferred embodiment of the invention is described in more detail below with reference to the drawing, in which: Fig. 1 schematic representation of a process, Fig. 2a a representation of a start screen of a communication medium, Fig. 2b a representation of a user interface of the communication medium, Fig. 2c a representation of another user interface, Fig. 2d a representation of another user interface, Fig. 2e a representation of another user interface, Fig. 2f a representation of another user interface, Fig. 2g a representation of another user interface, Fig. 2h a representation of another user interface, and Fig. 2i a representation of another user interface.

[0025] In the Fig. 1 The method according to the invention is shown schematically. For the method for carrying out an analysis, an identification and / or troubleshooting as well as a remote maintenance of a component of a vehicle 10, an operator or a vehicle driver is equipped with a mobile communication means 11. The vehicle 10 can be, as exemplified in the Fig. 1 shown, a truck. However, it is equally conceivable that the vehicle 10 is a different type of vehicle, such as a car, a construction vehicle, an agricultural machine or the like. The aforementioned component of the vehicle 10 can be a tail lift arranged on the vehicle 10 or a truck. However, it is equally conceivable that the component of the vehicle 10 is something other than a tail lift. The communication means 11 can, according to the Fig. 1 This could be a mobile phone or smartphone. However, other mobile communication devices, such as a tablet, are also suitable for carrying out the method according to the invention.

[0026] Essentially, the method described here serves to analyze, identify and / or rectify a malfunction or error message or defect of the component of the vehicle 10 or to maintain the component. As soon as there are indications that a malfunction, defect or error is present, such as a restriction of the functionality of the component, in a first step 12, in the Fig. 1 as a dashed box 12, to establish a connection between the mobile communication means 11 and the vehicle 10. This connection 13, in the Fig. 1 represented as a double arrow 13, can either be initiated automatically by a control unit or operating unit of the component after detection of a malfunction or error, so that corresponding information is displayed on the communication means 11. Alternatively, the driver of the vehicle 10 can establish or initiate the connection 13 to the component of the vehicle 10 via the communication means 11. According to the invention, the connection 13 is a near-field communication, such as a Bluetooth®< connection or a WLAN connection. In this connection 13, the communication means 11 couples to the control unit of the component. Embodiments are conceivable in which the initiation of this connection 13 only needs to be verified after corresponding passwords or codes have been successfully exchanged.

[0027] To carry out the method or to initialise the method, a program or software or a App The driver can download this in a familiar way, preferably free of charge, from a App-Store or similar from the Internet. The manufacturer of the component or tail lift provides a software tailored to the functions of the component. App About this App The driver can communicate, but also control the functions of the component.

[0028] As soon as communication has been established between the communication means 11 and the vehicle 10 or the component according to the first step 12, in a second step 14 all data for analysis, identification and / or troubleshooting and the like, which were transmitted in the first step from the vehicle 10 or the component to the communication means 11, can be transmitted via a connection 15 to an electronic data processing network 16. The data transmitted from the communication means 11 to the data processing network 16 are referred to as outgoing data. In this second step 14, the outgoing data are processed in the data processing network 16, which is a Cloud The data, which may be a fault, is further processed or analyzed, identified, and, if necessary, measures are generated for troubleshooting or remote maintenance. The connection 15 between the communication means 11 and the data processing network 16 is a far-field connection via WLAN, 5G, or IEEE802.1.

[0029] The data processing network 16 may be a network maintained by the component manufacturer. To access the data in this network 16, it is conceivable that users must register and authenticate. Alternatively, however, it is also conceivable that the data in the data processing network 16 can be freely accessed.

[0030] According to the invention, the outgoing data processed in the electronic data processing network 16 is transmitted back to the communication means 11 as incoming data via the connection 15. This can occur, for example, when querying specific error codes, information about service centers, or workshops within the range of the vehicle 10. Alternatively, it is also possible for the outgoing data to be transmitted from the data processing network 16 to a network application 17, or for the network application 17 to access the outgoing data in the data processing network 16. The network application 17 analyzes the outgoing data, in particular the identification data, the verification data, the operating parameters, and / or the error information data, and establishes a direct connection 18 to the communication means 11 depending on the analyzed data.The network application 17 can, for example, be a service partner or a service employee. This service partner, who may have registered to use the data processing network 16, provides the vehicle driver with at least one suggestion for correcting the error or malfunction. This can be done either via a text message, a voice message, a telephone call, or a video call. The connection 18 between the service partner and the vehicle driver is also a far-field connection via WLAN, 5G, or IEEE802.1. By accessing the data in the data processing network 16, which can be located almost anywhere, the service partner or the network application 17 can also perform the analysis, identification, and / or error correction regardless of location.On the other hand, the driver can, regardless of his location, use the data processing network 16 to access the . App access the service of the network application 17 on its communication means 11.

[0031] In addition, it is the case in the Fig. 1 In the schematically illustrated second step 14, it is conceivable that a fleet manager 20, who oversees and organizes several vehicles, including vehicle 10, also accesses the outgoing data of the communication means 11 in the data processing network 16. The fleet manager 20 can analyze the outgoing data, which it reads from the network 16 via a connection 21, and decide whether this will lead to a significant delay in a delivery process that needs to be compensated for by countermeasures. For example, it is conceivable that in the event of major damage, the fleet manager 20 could navigate a replacement vehicle to the location of the broken-down vehicle 10 so that the goods can be reloaded and delivery can continue.

[0032] In the Fig. 2a bis 2i There are different interfaces of the operating software or the App on the communication device 11, through which the driver can initiate or control the process. Fig. 2a a possible embodiment of a start screen of the App. After activating the App or the initialization of the connection 13, this App opened and vehicle-relevant data is loaded. It is conceivable that software updates are loaded at the same time or that connections to the network 16 and / or the network application 17 are already established. It may be necessary for the driver to first identify themselves before accessing the application. Likewise, it may be necessary to establish the connection 13 between the component and the communication means 11 via the App to verify.

[0033] The Fig. 2b shows an example of the appearance of a device manager. Here, various control units of the component are displayed and it is indicated whether they are connected to the communication device 11 or not. It is also shown whether these units or components are in range, ie available, or out of range, ie not available. Furthermore, the driver can use these in the Fig. 2b The interface shown allows the connection 13 to be easily connected or disconnected to the units or components by operating the control panel.

[0034] The Fig. 2c represents a possible example of a menu overview. Here the driver can choose between a Dashboard, the device manager, emergency operation, troubleshooting, service overview and service search. Fig. 2d shown as examples Dashboard This is a virtual instrument panel or a virtual dashboard. Dashboard represents a central user interface of the communication device 11. Here, the driver can see the status of the most important components at a glance and initiate further procedural steps using simple and intuitive command options. The four options displayed in the lower half of the user interface offer the possibility of initiating troubleshooting, emergency operation, a service overview, or a service search. Depending on which of these options is selected by the driver, various connections 15, 18, 19, 21, or 13 can be established.

[0035] The Fig. 2e, 2f and 2i show examples of various menu navigation for troubleshooting, error details, and a virtual error log. The user interface according to Fig. 2g provides an overview of various service functions.

[0036] In the Fig. 2h An example of a user interface for emergency operation is shown. The large control panels, clear commands, and symbols allow the various emergency operation options to be used without any ambiguity. Furthermore, the driver is notified that emergency operation has been activated when emergency operation is initiated. This can be done acoustically, visually, or haptically.

[0037] A further embodiment of the application software can provide that a language is to be selected right at the beginning of the process, so that subsequently all menu items of the App be displayed in a language that the driver understands.

[0038] In addition to the examples of the user interfaces shown here, Fig. 2a bis 2i Other control panels and designs are also conceivable. The method according to the invention is expressly not intended to be limited to the Fig. 2a bis 2i The functions shown may be limited. Bezugszeichenliste:
