Description

[0001] The invention relates to a method for recording the setup of a test bench and for guiding the setup of a test bench, in particular a test bench of a powertrain of a motor vehicle.

[0002] Setting up a test bench is a complex task involving numerous manual steps that must be performed in a specific sequence and manner. This is a complex undertaking for an experienced technical expert with extensive experience in building such test benches. For a non-expert to undertake the construction of a test bench is a difficult and complex challenge, and transferring the know-how of test bench construction from an experienced technical expert to a non-expert is a difficult endeavor.

[0003] The task is therefore to create a method for recording and guiding the setup of a test bench, in particular a test bench for a motor vehicle powertrain, which can also be used by non-experts to efficiently set up a test bench. It is also the task to create a device for carrying out the method.

[0004] The problem is solved using the features of claim 1.

[0005] One embodiment of the invention relates to a method for recording the setup of a test rig by an operator, wherein the operator wears tactile gloves while performing manual tasks, which have tactile sensors for detecting the manual actions, wherein the signals and data of the tactile sensors of the tactile gloves are processed and stored, wherein a task is generated from the processed and stored signals and data, which is transmitted to another operator as instructions for setting up a test rig.This allows an experienced operator to set up the test bench, and the manual activities of the experienced operator are recorded and evaluated. From this, instructions for setting up such a test bench are generated for a less experienced operator, so that even without experience, they can understand how to set up such a test bench and carry it out themselves with appropriate guidance.

[0006] In one embodiment, it is also advantageous to divide the signals and data from the tactile sensors into tactile signals and tactile sequences for different manipulation tasks. This allows the operator's movements and / or actions to be broken down into individual movement steps and sequences, which can then be assigned to the corresponding manipulation tasks so that they can be carried out under guidance by another operator.

[0007] It is also advantageous to categorize the signals and data from the tactile sensors of a right and a left tactile glove as tactile signals and tactile sequences for different manipulation tasks. This allows the movements and / or actions of both hands to be recorded using the two tactile gloves and assigned to manipulation tasks. The various movements and / or actions can then be recognized and assigned to different manipulation tasks. These manipulation tasks can also be classified for use in various tasks and activities.

[0008] It is particularly advantageous if the following are considered manipulation tasks: mounting a sensor, connecting a sensor, using a screwdriver, lifting a component, etc. Such manipulation tasks represent typical tasks that an operator must perform when setting up a test bench.

[0009] In one embodiment, it is also advantageous to encrypt the signals and data and embed them in an environment. This allows the data to be handled and processed within a software model.

[0010] It is particularly advantageous if the encrypted embedding is carried out using an energy-based model. This allows energies to be assigned to different movements and / or actions, whereby, for example, energy minimization can be performed when linking and / or chaining such movements and / or actions to facilitate the selection of the movements and / or actions to be performed by the subsequent operator.

[0011] It is also advantageous if the energy-based model includes at least one latent variable. This allows the energy-based model to refer to previously taken steps, for example.

[0012] It is also advantageous if the energy-based model is used to generate a manual operation task, which is then transmitted to another operator as instructions for the next step in setting up a test bench. Such instructions can be conveyed to the other operator visually (in an image, a sequence of images, a video, text, or audio) to guide them through the subsequent manual operation.

[0013] Accordingly, it is also advantageous if the transmission to the other operator is visual and / or acoustic.

[0014] The objective of the device is achieved with the features of claim 10.

[0015] For example, a device for carrying out a procedure has two tactile gloves, one for the right hand and one for the left hand, as well as a computing, storage and / or evaluation unit, and also provides output means for optical and / or acoustic output to another operator.

[0016] The invention will now be explained in detail using exemplary embodiments and with reference to the drawings. The drawings show: Fig. 1 a schematic representation of an exemplary embodiment of a test rig to be built, and Fig. 2. Another schematic representation of a process flow.

[0017] The invention relates to a method for an operator to record the setup of a test rig 1. Fig. Figure 1 shows an example of such a test bench 1. The test bench 1 includes, for example, a DC supply line 2, a DC current sensor 3, a DUT converter 4, an AC current sensor 5, a coolant supply 6, a computing, storage and / or evaluation unit 7, a current sensor amplifier 8 and other components.

[0018] The device for carrying out the method according to the invention further provides, for example, two tactile gloves 10, one tactile glove 10 for the right hand and one tactile glove 10 for the left hand, as well as the computing, storage and / or evaluation unit 7 and output means 9.

[0019] During the setup of test rig 1, an experienced operator performs manual tasks while wearing tactile gloves 10. The tactile gloves 10 are equipped with numerous tactile sensors 19 that detect manual actions, movements, etc., allowing the operator's manual actions to be recorded and the corresponding signals and data to be processed and stored.

[0020] The data and signals of the tactile gloves 10 can be represented in a number of tactile sequences 11 of the right hand and in a number of tactile sequences 11 of the left hand, see Fig. 2. These tactile sequences can be encrypted using tactile encoders 12 and embedded in an environment 13.

[0021] Subsequently, the data and / or signals can be decoded by various decoders 14, a classification decoder, an object dynamics decoder and / or a tactile dynamics decoder, and a task 15 can be generated from the processed and stored signals and data, see decoder 16, which can be transmitted to another, especially inexperienced, operator as instructions for setting up a test bench 1.

[0022] It is particularly advantageous if the signals and data from the tactile sensors 19 of the tactile gloves 10 are subdivided into tactile signals and tactile sequences 11 for different manipulation tasks. It is especially advantageous if the signals and data from the tactile sensors 19 of a right tactile glove 10 and a left tactile glove 10 are subdivided into tactile signals and tactile sequences 11 for different manipulation tasks. In this way, a corresponding manipulation task can be assigned based on the different movements and actions of the two hands.

[0023] Such manipulation tasks can include, for example: mounting a sensor, connecting a sensor, using a screwdriver, lifting a component, etc.

[0024] Embedding can be achieved, for example, using an energy-based model 17. This energy-based model 17 can also include at least one latent variable. This latent variable can, for example, originate from and / or relate to the preceding work step or task, and thus influence the next work step or task.

[0025] It can also be used to create and, for example, output a summary of work tasks. This allows the next operator to be informed of the next task or work step.

[0026] The work steps, tasks, and their descriptions can also be stored in a database (see 18). These can also be classified, for example, by task type, sequence, etc. Reports on the setup of a test bench 1 can be generated from this data, for example, in different languages. A summary of the work tasks performed using the tactile gloves 10 for the setup or assembly of the test bench 1 can also be generated.

[0027] The summary can also be used to provide a prediction or instruction to the inexperienced operator regarding the next work step or task.

[0028] The procedure can be repeated step by step for each work step or task in order to record the setup of test bench 1 step by step and to process and save the data and signals accordingly, in order to have recorded all manually performed tasks, movements and operations after completion of the setup of test bench 1, in order to subsequently instruct an inexperienced operator to be able to set up test bench 1 himself without major expertise.

[0029] Using the energy-based model 17, a task for manual operation can be generated, which is transmitted to another operator as instructions for the next work step in setting up a test bench 1.

[0030] The information can be transmitted to the next operator visually and / or audibly, in particular via text, image and / or film sequence or image sequence.
