Description

The present invention relates to a test device for testing at least one component of a door of a vehicle. The invention also relates to a method for testing at least one component of a door of a vehicle.

It is known from the prior art that when assembling vehicle parts and components, the correct installation position is checked.

However, especially in the case of pre-assembly of the door, incorrect or faulty installations of locks, door control devices, wiring harnesses and / or high and low-frequency loudspeakers can occur. Conventional test methods for this door pre-assembly are often technically complex and / or costly.

From the scriptures DE 10 2004 024 704 A1 , US 2009/0274312 A1 , EP 0 841 570 A2 , US 9 117 319 B2 and US 2003/0 218 356 A1 test devices of vehicles for testing vehicle components are known.

It is therefore an object of the present invention to at least reduce the disadvantages described above. In particular, it is an object of the present invention to provide an improved and / or technically simpler test.

The above object is achieved by a test device with the features of claim 1 and by a method with the features of claim 9. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. Features and details that are described in connection with the test device according to the invention naturally also apply in connection with the method according to the invention, and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or can always be made to the individual aspects of the invention.

The object is achieved in particular by a test device for testing at least one component of a door of a vehicle. The vehicle can be designed, for example, as a motor vehicle and / or passenger vehicle and / or electric vehicle.

• - eine (insbesondere nicht-flüchtige) Speichervorrichtung zur (insbesondere nichtflüchtigen) Speicherung wenigstens einer Soll-Information,
• - eine Schnittstellenvorrichtung zur Verbindung mit einem Datenübertragungssystem der Tür, um wenigstens eine Ist-Information über die wenigstens eine Komponente zu erhalten,
• - eine (insbesondere elektronische) Verarbeitungsvorrichtung zum Vergleichen der wenigstens einen Ist-Information mit der wenigstens einen Soll-Information,
• - eine (insbesondere elektronische) Lautsprecherprüfvorrichtung zur elektrischen Auswertung wenigstens eines Lautsprechers der Tür.

A test device according to the invention can have the following test components, which are preferably electrically connected to one another (in particular permanently), in particular at least partially via conductor tracks of at least one circuit board:

• - a (in particular non-volatile) storage device for (in particular non-volatile) storage of at least one item of target information,
• - an interface device for connection to a data transmission system of the door in order to receive at least one piece of actual information about the at least one component,
• - a (in particular electronic) processing device for comparing the at least one actual information item with the at least one target information item,
• - A (in particular electronic) loudspeaker testing device for the electrical evaluation of at least one loudspeaker in the door.

This has the advantage that, in a technically simplified manner, the test device can read out the essential information about the interface device in order to carry out the test on the basis of this read-out information (i.e. in particular the actual information). In this way, the technical and thus also the cost effort can be reduced. At the same time, a particularly compact design for a test device can be made possible if the loudspeaker test device is integrated into the test device according to the invention at the same time.

Advantageously, the test device according to the invention can be designed as an individually manageable and / or mobile and / or unitary test device. The test device preferably also has its own power supply, for example an accumulator. The test device according to the invention can optionally have only one or two circuit boards on which electrical components and / or integrated circuits for providing the memory device and / or interface device and / or processing device and / or loudspeaker test device are arranged. At least one of these circuit boards can be part of a single-board computer such as a Raspberry Pi. In other words, a single-board computer can be designed to carry out the test, in particular a control and measured value acquisition.

The loudspeaker testing device can advantageously have an analog-digital converter in order to measure at least one loudspeaker resistance of the at least one loudspeaker of the door. If necessary, actual information about the at least one loudspeaker can be determined on the basis of this measurement, which is specific for a resistance value, for example. By comparing this actual information with a target Information for the at least one loudspeaker can be used to determine a deviation in the resistance value in a specific range, and thus it can be determined whether the at least one loudspeaker is plugged in.

The comparison and / or the at least one item of target information can be used to test the at least one component and / or for the loudspeaker test. The comparison can be used, for example, to determine if there is a faulty installation position of at least one of the at least one component and / or if an incorrect component has been installed. The at least one component can include, for example, a control device and / or a lock and / or a cable harness. If at least one of the at least one components is designed as the control unit, the comparison can be used to determine, for example, whether a control unit intended for the passenger side has been installed in the driver's side, or vice versa. If at least one of the at least one components is designed as the wiring harness, it can be established, for example, if the wiring harness is not plugged in, is damaged or has been incorrectly selected. If at least one of the at least one components is designed as the lock, it can be determined, for example, if the lock was not inserted or incorrectly installed or incorrectly selected. If necessary, at least one of the at least one components can also be designed as at least one loudspeaker, so that the functionality of the at least one loudspeaker can be determined by the test. For the comparison, for example, a computer program can be stored in the storage device or in a further storage device and / or executed by the processing device.

It is also conceivable that the test device with all parts with the exception of a plug connection of the interface device is accommodated in a housing. Accordingly, it is not necessary for the processing device or a computer, such as the single-board computer, to be accommodated in the connector itself. The test device according to the invention is thus possibly less sensitive to disturbances and external influences.

It may be possible within the scope of the invention that the at least one target information is a specification for the test, in particular a specification for the at least one component, particularly preferably a specification for a control device and / or a lock and / or a loudspeaker system of the door includes. A first of the at least one set of items of information can be, for example, information about which type of vehicle the vehicle is, whether it is a left-hand drive or a right-hand drive and / or which lock type is provided. It can also be information about the specification of a mating connector of the door, in particular a door isolating plug of the door, preferably as a front door.

It is advantageously provided that, during the comparison, each of the at least one target information item is compared with the associated at least one actual item of information. If the compared information does not match, an error can be output for a user of the test device. This error output is shown, for example, visually on a display device and / or acoustically and / or the like.

The door can be designed, for example, as a front door or as a rear door, the test device according to the invention optionally being designed for testing different doors.

The at least one loudspeaker can be designed, for example, as a tweeter and / or as a woofer. The loudspeaker test device carries out, for example, a test of the resistances of the at least one loudspeaker and / or the plugging of the loudspeakers (i.e. in particular a correct electrical connection to the control device).

The loudspeaker testing device preferably carries out a resistance measurement independently of the comparison of the actual information with the target information for the control device and / or for the lock. In particular, the loudspeaker testing device is designed at least partially separately from the processing device, in particular as a system made up of various electrical elements, such as, for example, an analog-to-digital converter and / or an integrated circuit. It can also be possible for the loudspeaker testing device to be provided at least partially by the processing device, for example in order to process the measurement data during the resistance measurement.

Furthermore, it is conceivable that the interface device for connection to the data transmission system is designed as a bus system, in particular a CAN bus system. In other words, the data transmission system can be designed as the bus system, in particular a CAN bus system. CAN stands for Controller Area Network. Correspondingly, the interface device can be designed as a CAN bus interface device and thus be adapted to the evaluation of CAN bus data. Preferably, at least one of the at least one component is designed for this purpose, at least one of the at least to transmit actual information via the CAN bus system to the interface device. This has the advantage that the actual information can be determined in a simple manner.

Another advantage within the scope of the invention can be achieved if an input device is provided in order to record the at least one item of target information. The input device can for example comprise a keyboard and / or a voice input and / or a barcode scanner and / or a touchscreen. This enables convenient parameterization of the test by the test device according to the invention.

In addition, it can be advantageous within the scope of the invention that the input device has a barcode scanner. In this way, a particularly fast parameterization of the test can take place, which brings a clear time advantage, especially when assembling different doors. For example, an operator of the test device can scan a barcode through the barcode scanner, this barcode preferably being attached to the door to be tested. The barcode encompasses, for example, at least one of the at least one target information encoded.

Furthermore, it can be provided that the input device has a network interface and is designed to receive the at least one item of target information from a database via the network interface. The database can be provided, for example, by a central data processing device, such as a server, and in particular can be transmitted to the test device via the Internet by means of the network interface. This enables a particularly flexible adaptation of the at least one target information item.

It is also conceivable within the scope of the invention that the interface device has at least or precisely one connector for connection to a respective mating connector of the door. The connector is connected, for example, via a cable to a circuit board of the test device in order to be flexibly and, in particular, releasably connected to the mating connector of the door. This enables a particularly convenient test when installing the door.

It is also advantageous if the interface device has a power supply connection for the at least one component and / or a test connection for the at least one loudspeaker. This makes it possible to supply the at least one component for the test directly with electrical energy and to operate it with it.

Furthermore, it can be provided within the scope of the invention that the loudspeaker test device is designed to measure electrical resistance and preferably has an analog-digital converter for connection to the at least one loudspeaker via a test connection of the interface device. In this way, a very comprehensive function test can be provided by the test for the door.

• - ein Steuergerät, welches mit dem Datenübertragungssystem zur Übertragung der Ist-Information verbunden ist,
• - ein Türschloss, welches insbesondere elektrisch mit dem Steuergerät verbunden ist,
• - wenigstens ein Lautsprecher.

It is also possible within the scope of the invention that the at least one component is designed as at least one of the following components of the door:

• - a control unit which is connected to the data transmission system for the transmission of the actual information,
• - a door lock, which is in particular electrically connected to the control unit,
• - at least one loudspeaker.

For example, it can be provided that the processing device is designed to use the comparison to check an installation position (at least one) of the at least one component, and preferably to differentiate between a left-hand installation on the vehicle and a right-hand installation on the vehicle using the target information. One idea of the invention here is that different components are mounted in a left-hand door (which is mounted on the left-hand side of the vehicle) than in a right-hand door (which is mounted on the right-hand side of the vehicle). A test device according to the invention can be used to determine when the assembly of the at least one component has been reversed.

The invention also relates to a method, in particular a testing and / or assembly method, for testing at least one component of a door of a vehicle, preferably during or after assembly of the door.

• - Durchführen einer elektrischen Auswertung wenigstens eines Lautsprechers der Tür,
• - Bereitstellen eines Prüfungsergebnisses anhand des Vergleichs und der Auswertung.

It is provided here that the following steps are carried out, preferably one after the other or in any order, and in particular in each case by a test device according to the invention:

• - Provision of at least one target information item, in particular by means of a storage device and / or an input device,
• - Reading out at least one piece of actual information about the at least one component by means of an interface device for connection to a data transmission system of the door,
• - Carry out a comparison of the actual information with the target information,
• - Carrying out an electrical evaluation of at least one loudspeaker in the door,
• - Providing a test result based on the comparison and the evaluation.

This test result can, for example, include information on whether the at least one component was correctly installed on the door. The test result can preferably be output by an output device for a user of the test device. This output device is designed, for example, as a display or as an acoustic output device.

The method according to the invention thus brings the same advantages as have been described in detail with reference to a test device according to the invention. In addition, the method can be suitable for operating a test device according to the invention.
