- the correct connection of trailers or the successful coupling can also be checked.
- These components can advantageously be checked by one or more detection devices positioned inside and outside.

- the detection device is preferably designed to be able to check the state of one or more components while the vehicle is driving. This allows problems such as defective components or components that may soon be defective due to advanced wear to be identified. Especially when there is no driver in autonomous vehicles, this option of monitoring components while driving is helpful in order to avoid accidents.
- the temperature of the brakes can be monitored with an infrared camera.
- a single movable infrared camera can monitor the temperatures of all brakes and can thus replace several individual sensors.

- the system preferably includes a communication device, by means of which information relating to the status of a component can be transmitted to a control center.
- information about several vehicles can be collected and possibly also processed. This makes it easier to organize necessary repairs and/or spare parts, for example.

For example, locking devices such as doors and tailgates can be checked, which can be done with optical sensors, for example. A functional test of the lighting device of the vehicle 5 can also be carried out using light sensors. It is also possible for a detection device 10 on a carriage 13 to include different sensors in order to check different components with the appropriate sensor as required, for example by optical imaging to check a closure device and by light sensor to check the lighting device.

- the detection devices 10 it is also possible for the detection devices 10 to be used continuously or intermittently while driving.
- a detector 10 on the underside of the vehicle 5 could monitor the temperature of the brakes using an infrared camera. Due to the mobility, a detection device 10 with a sensor that can cover all areas with brakes is sufficient for this purpose. While a quasi-continuous check is thus possible alternately between the brakes, the detection device 10 could also be active at specific time intervals, as a result of which energy can be saved.

However, it is also conceivable for the check to be carried out remotely, for example from the control center. In this embodiment, when the drone 14 is not in use, it is located in a closed area 11 which can be closed by a flap 11a. Alternatively, other locking mechanisms are also possible, such as a sunroof.
- the drone 14 is protected from external influences and energy can be saved in an idle state.
- there is a docking station in the closed area to which the drone 14, e.g. B. via an electrical connection, can be charged with energy.

Es ist aus dem Stand der Technik bekannt, dass ein Fahrzeug im Rahmen autonomen Fahrens ohne Fahrer unterwegs sein kann. Beispielsweise kann es sich bei dem Fahrzeug um ein Nutzfahrzeug, insbesondere einen Lastkraftwagen handeln. Die Prüfung sicherheitsrelevanter und tragender Teile des Fahrzeugs vor Fahrtantritt wird bisher typischerweise durch einen Fahrer zum Beispiel per Sichtprüfung durchgeführt. Bei Wegfall des Fahrers muss diese Aufgabe entsprechend durch eine zusätzliche Person durchgeführt werden. Ferner kennt der Stand der Technik Vorrichtungen, die selbsttätig bzw. aktiv Signale bzw.

Um autonomes Fahren im vollen Umfang realisieren zu können, ist es daher Aufgabe der Erfindung, eine Möglichkeit zu finden, die Überprüfung vor Fahrtantritt vollautomatisch durchführen zu können und weiterhin auch mögliche technische Probleme automatisch während der Fahrt frühzeitig detektieren zu können. Dabei soll das verwendete System möglichst kostengünstig und materialsparend sein.In order to be able to realize autonomous driving to the full extent, it is therefore the object of the invention to find a way of being able to carry out the check fully automatically before the start of the journey and also to be able to also automatically detect possible technical problems early on during the journey. The system used should be as cost-effective and material-saving as possible.
Diese Aufgabe wird gelöst durch ein Fahrzeug gemäß Anspruch 1 und ein Verfahren gemäß Anspruch 10. Weitere Vorteile und Eigenschaften ergeben sich aus den abhängigen Ansprüchen sowie der Beschreibung und den beigefügten Figuren.This object is achieved by a vehicle according to
Gegenüber den aus dem Stand der Technik bekannten Systemen zum Überprüfen des Zustands von Komponenten ist es erfindungsgemäß vorgesehen, in einem festgelegten Bereich am Fahrzeug Informationen zu erfassen. Auf diese Weise können beispielsweise im Rahmen einer Abfahrtskontrolle vorteilhaft mehrere Komponenten überprüft werden. Die gesammelten Informationen können dann in Form eines Datensatzes bevorzugt über eine drahtlose Übertragung an eine Auswerteeinrichtung weitergeleitet und dort analysiert werden. Alternativ kann die Weiterleitung der Daten auch über Kabel geschehen. Die Auswerteeinrichtung umfasst beispielsweise einen Computer, der dazu ausgelegt ist, anhand des aufgenommen Datensatzes den Zustand der überprüften Komponente festzustellen. Die Auswerteeinrichtung kann dabei in das Fahrzeug integriert sein oder in eine externe Zentrale. Umfasst der Datensatz beispielsweise ein optisch aufgenommenes Bild, so kann ein Abgleich mit einem oder mehreren Soll-Bildern durchgeführt werden, um den Zustand der Komponente zu bewerten. Die Abfahrtkontrolle kann auf diese Weise voll automatisiert durchgeführt werden. Alternativ kann sie auch durch eine Person ferngesteuert durchgeführt werden oder zumindest teilweise durch eine Person überwacht werden, zum Beispiel in Form einer teilautomatisierten Abfahrtkontrolle. Dadurch, dass die Erfassungseinrichtung mit dem Fahrzeug mitgeführt werden kann, ist eine Abfahrtskontrolle an jedem Ort möglich und insbesondere unabhängig von am Abfahrtsort vorhandenen Messeinrichtungen oder anwesendem Personal. Dabei ist es vorzugsweise vorgesehen, dass zumindest während einer Erfassung des Datensatzes zwischen der Erfassungseinrichtung und dem festgelegten Bereich zumindest zeitweise, vorzugsweise stets, ein Abstand von mindestens 10 cm, bevorzugt mindestens 30 cm und besonders bevorzugt mindestens 50 cm herrscht. Die Erfassungseinrichtung ist somit vorteilhafterweise gegenüber dem festgelegten Bereich beabstandet.In contrast to the systems known from the prior art for checking the condition of components, the invention provides for information to be recorded in a defined area on the vehicle. In this way, several components can advantageously be checked, for example as part of a departure check.

Alternatively, the data can also be forwarded via cable. The evaluation device includes a computer, for example, which is designed to use the recorded data set to determine the status of the checked component. The evaluation device can be integrated in the vehicle or in an external control center. For example, if the data record includes an optically recorded image, a comparison with one or more target images can be carried out in order to evaluate the condition of the component. In this way, the departure check can be carried out fully automatically. Alternatively, it can also be carried out remotely by a person or at least partially monitored by a person, for example in form a partially automated departure check. Because the detection device can be carried along with the vehicle, a departure check is possible at any location and, in particular, independently of the measuring devices present at the departure location or the personnel present. It is preferably provided that at least temporarily, preferably always, there is a distance of at least 10 cm, preferably at least 30 cm and particularly preferably at least 50 cm between the acquisition device and the specified area during acquisition of the data set. The detection device is thus advantageously at a distance from the defined area.
Die Erfassungseinrichtung umfasst erfindungsgemäß einen Sensor, der beispielsweise auf dem Erfassen und/oder Aussenden von elektromagnetischen Wellen und/oder Schallwellen basiert. Dies kann zum Beispiel eine Videokamera sein, die Informationen in Form von optischen Aufnahmen, bevorzugt in Form eines oder mehrerer Bilder, von einem festgelegten Bereich im oder am Fahrzeug sammelt und somit beispielsweise eine oder mehrere Komponenten des Fahrzeugs erfasst. Ein aufgenommenes Bild kann dann vorzugsweise mit Hilfe eines Bildauswerteprogramms der Auswerteeinrichtung verarbeitet werden und zum Beispiel mit einem Soll-Bild abgeglichen werden, um Veränderungen in dem Bereich oder an einer oder mehrerer Komponenten festzustellen. Aber auch Messungen im infraroten Spektralbereich mit Hilfe von Infrarotsensoren sind denkbar, um beispielsweise die Temperatur einer oder mehrerer Komponenten zu überprüfen und zum Beispiel ein Überhitzen rechtzeitig zu detektieren. So ist es denkbar, die Temperatur der Bremsscheiben auf diese Art zu überwachen. Weitere denkbare Sensoren können u.a. Lichtsensoren, Radarsensoren, auf Lasern basierte Messanordnungen, Ultraschallsensoren und Mikrofone sein. Mit Mikrofonen können die Geräusche im Fahrzeugbetrieb überwacht werden, um beispielsweise ein Stottern des Motors frühzeitig zu erkennen. Es sind aber auch andere Arten von Sensoren denkbar. So können Temperaturmessgeräte wie zum Beispiel Widerstandsthermometer oder Thermoelemente verwendet werden, um die Temperatur eines oder mehrerer Komponenten zu überprüfen. Auch ein Drucksensor ist denkbar, der beispielsweise eingesetzt werden kann, um den Reifendruck zu überprüfen. Dehnungsmessstreifen können eingesetzt werden um Verformungen von Komponenten, wie beispielsweise der Karosserie zu erkennen. Auch der Einsatz einer HallSonde ist denkbar, um beispielsweise die Abschirmung elektrischer Leitungen oder von Spannungsumwandlern im Fahrzeug, insbesondere in einem Elektrofahrzeug, zu überprüfen. Starke magnetische Felder könnten zum Beispiel eine Steuerelektronik des Fahrzeugs negativ beeinflussen. Grundsätzlich ist es auch denkbar, dass die Erfassungseinrichtung aus mehreren Sensoren besteht, insbesondere ist auch eine Kombination verschiedener Sensoren möglich. Das Abgleichen der Messwerte verschiedener Sensoren kann eine höhere Sicherheit liefern. Zusätzlich kann auch eine detailliertere Analyse einer Komponente ermöglicht werden. So könnte zum Beispiel erkannt werden, wenn sich eine Komponente aufgrund von Überhitzung verformt hat, indem gleichzeitig die Form und die Temperatur der Komponente überwacht werden. Besonders bevorzugt ist es vorgesehen, dass die Erfassungseinrichtung eine Datensammeleinrichtung umfasst, die mit mehreren Sensoren in Kontakt steht, und die von den Sensoren ausgehenden Informationen sammelt und an die Auswerteeinrichtung weiterleitet. Dabei kann die Datensammeleinrichtung beispielsweise von den Sensoren beabstandet sein, beispielsweise mindestens 10 cm, bevorzugt mindestens 20 cm und besonders bevorzugt mindestens 50 cm.According to the invention, the detection device comprises a sensor which is based, for example, on the detection and/or emission of electromagnetic waves and/or sound waves. This can be a video camera, for example, which collects information in the form of optical recordings, preferably in the form of one or more images, from a specified area in or on the vehicle and thus, for example, captures one or more components of the vehicle. A recorded image can then preferably be processed using an image evaluation program of the evaluation device and, for example, compared with a target image in order to determine changes in the area or in one or more components. However, measurements in the infrared spectral range using infrared sensors are also conceivable, for example to check the temperature of one or more components and, for example, to detect overheating in good time. So it is conceivable to monitor the temperature of the brake discs in this way. Other conceivable sensors can include light sensors, radar sensors, laser-based measuring arrangements, ultrasonic sensors and microphones. The noises during vehicle operation can be monitored with microphones, for example to detect engine stuttering at an early stage. However, other types of sensors are also conceivable. For example, temperature measuring devices such as resistance thermometers or thermocouples can be used to check the temperature of one or more components. A pressure sensor is also conceivable, for example can be used to check tire pressure. Strain gauges can be used to detect deformations in components such as the body. The use of a Hall probe is also conceivable, for example to check the shielding of electrical lines or of voltage converters in the vehicle, in particular in an electric vehicle. Strong magnetic fields could, for example, have a negative impact on the vehicle's control electronics. Basically, it is also conceivable that the detection device consists of several sensors, in particular a combination of different sensors is also possible. Comparing the readings from different sensors can provide greater security. In addition, a more detailed analysis of a component can also be enabled. For example, it could detect when a component has deformed due to overheating by simultaneously monitoring the component's shape and temperature. Provision is particularly preferably made for the detection device to comprise a data collection device which is in contact with a number of sensors and collects the information coming from the sensors and forwards it to the evaluation device. The data collection device can, for example, be at a distance from the sensors, for example at least 10 cm, preferably at least 20 cm and particularly preferably at least 50 cm.
Zweckmäßigerweise ist die Erfassungseinrichtung mobil und/oder schwenkbar, vorzugsweise um eine, zwei oder drei Achse, und/oder beweglich und/oder ortsveränderlich. Erfindungsgemäß ist die Erfassungseinrichtung, insbesondere die Datensammeleinrichtung, auf einem Bewegungsmittel positioniert. Besonders bevorzugt ist es vorgesehen, wenn die Erfassungseinrichtung sowohl ortsveränderlich als auch schwenkbar ist. Dadurch lassen sich durch entsprechende Ausrichtungen der Erfassungseinrichtung auch voneinander entfernte, zu erfassende Bereiche mit einer Erfassungseinrichtung, insbesondere einer einzigen Erfassungseinrichtung, untersuchen.The detection device is expediently mobile and/or pivotable, preferably about one, two or three axes, and/or movable and/or variable in location. According to the invention, the detection device, in particular the data collection device, is positioned on a moving means. Provision is particularly preferably made for the detection device to be both mobile and pivotable. As a result, by appropriately aligning the detection device, regions to be detected that are distant from one another can also be examined with one detection device, in particular a single detection device.
Die Erfassungseinrichtung, insbesondere das Bewegungsmittel ist erfindungsgemäß ein Schlitten auf einem Schienensystem.According to the invention, the detection device, in particular the movement means, is a carriage on a rail system.
Erfindungsgemäß weist die Erfassungseinrichtung und/oder das Bewegungsmittel einen Antrieb auf. Dieser Antrieb kann elektrisch, pneumatisch, hydraulisch und/oder mechanisch sein. Durch die Mobilität kann die Erfassungseinrichtung vorteilhafter Weise an mehreren Orten eingesetzt werde. Dadurch können u. a. Kosten eingespart werden, da insgesamt weniger Erfassungseinrichtungen benötigt werden, um alle relevanten Komponenten des Fahrzeugs abzudecken. Vorzugsweise erstreckt sich das Schienensystem in Längsrichtung des Fahrzeugs. Beispielsweise ist das Schienensystem an einer Oberseite und/oder Unterseite eines Anhängers angebracht. Dabei ist das Schienensystem vorzugsweise in Querrichtung gesehen mittig und/oder an Randbereichen der Oberseite und/oder Unterseite des Fahrzeugs, insbesondere des Anhängers, angeordnet. Vorzugsweise erfasst die Erfassungseinrichtung mehrere festgelegte Bereiche, wobei jeder festgelegte Bereich mindestens eine zu überprüfende Komponente umfasst. Dies kann einerseits durch Mobilität bzw. Ortsveränderlichkeit der Erfassungseinrichtung ermöglicht werden. Andererseits kann die Erfassungseinrichtung aber auch drehbar bzw. schwenkbar sein und damit von einem Ort aus mehrere Bereiche abdecken, d. h. erfassen. Unter "Erfassen" ist bevorzugt die Aufnahme bzw. der Empfang eines Datensatzes zu verstehen. Alternativ ist es auch vorstellbar, dass die Erfassungseinrichtung mehrere hintereinander oder nebeneinander liegende Bereiche abdeckt und zum Beispiel durch Ändern der Fokussierung und/oder Herausfiltern von Teilen der aufgenommenen Informationen jeweils einen anderen Bereich erfasst.According to the invention, the detection device and/or the movement means has a drive. This drive can be electric, pneumatic, hydraulic and/or mechanical. Due to the mobility, the detection device can advantageously be used at several locations. As a result, costs can be saved, among other things, since fewer detection devices are required overall to cover all relevant components of the vehicle. The rail system preferably extends in the longitudinal direction of the vehicle. For example, the rail system is attached to a top and/or bottom of a trailer. The rail system is preferably arranged in the center and/or on edge regions of the top and/or bottom of the vehicle, in particular the trailer, as seen in the transverse direction. The detection device preferably detects a plurality of specified areas, with each specified area comprising at least one component to be checked. On the one hand, this can be made possible by mobility or the ability to change location of the detection device. On the other hand, the detection device can also be rotatable or pivotable and thus cover, ie detect, several areas from one location. “Capturing” is preferably to be understood as meaning the recording or receipt of a data record. Alternatively, it is also conceivable that the detection device covers several areas lying one behind the other or next to one another and, for example, by changing the focus and/or filtering out parts of the recorded information, detects a different area in each case.
Erfindungsgemäß ist die Erfassungseinrichtung an der Außenseite des Fahrzeugs positioniert. Dies ermöglicht es in vorteilhafter Weise, auch außen liegende Komponenten des Fahrzeugs, wie zum Beispiel einen oder mehrere Reifen, Verriegelungsmechanismen oder die äußere Karosserie, zu überprüfen.According to the invention, the detection device is positioned on the outside of the vehicle. This advantageously makes it possible to also check external components of the vehicle, such as one or more tires, locking mechanisms or the outer body.
Vorzugsweise ist die zu erfassende mindestens eine Komponente Teil einer Karosserie und/oder Teil eines Fahrwerks und/oder Teil eines Antriebs und/oder Teil einer Verbindungstechnik des Fahrzeugs. Die Karosserie bzw. der Aufbau kann dabei eine Rohkarosserie (Türen, Hauben und Verdeck), ein Führerhaus, Verglasung, Dichtungen, Türschlösser, Scheibenwischanlage, Beleuchtungseinrichtungen, Stoßfänger, Instrumente, Sitze, z. B. für eventuelle Passagiere, Innenverkleidungen, Heizung und Klimatisierung und eine oder mehrere Batterien umfassen. Diese Komponenten können zum Beispiel durch optische Sensoren überprüft werden, um Beschädigungen, wie z. B. Verformungen oder Risse, oder auch defekte Beleuchtungseinrichtungen, wie z. B. defekte Scheinwerfer oder Fahrtrichtungsanzeiger, zu erkennen. Heizung und Klimatisierung könnten dagegen zum Beispiel durch Infrarotsensoren überprüft werden. Das Fahrwerk umfasst ein Fahrgestell, das auch als Rahmen bezeichnet wird, Felgen, Reifen und Räder, Radführung, Federung, Bremsen und eine Lenkung. Auch für die Komponenten des Fahrwerks ist zum Beispiel eine optische Überprüfung hinsichtlich von Schäden möglich. Zudem kann auch die Temperatur einzelner Komponenten, insbesondere der Bremsen, beispielsweise durch einen Infrarotsensor detektiert werden. Der Antrieb umfasst einen Motor, eine Motorkühlung, Energiespeicher sowie Drehmomentwandler mit Kupplung und Schaltgetriebe. Die Verbindungstechnik umfasst eine oder mehrere Verschlusseinrichtungen, wie zum Beispiel Türschlösser, Ladungssicherung, Anhänger-/Sattelanhängerbetrieb und Kupplung. Hierbei kann beispielsweise überprüft werden, ob Türen oder andere Verschlusseinrichtungen ordnungsgemäß verschlossen sind, um einen Verlust einer Ladung beispielsweise durch Herunterfallen oder Diebstahl zu vermeiden. Auch kann der ordnungsgemäße Anschluss von Anhängern bzw. das erfolgreiche Kuppeln überprüft werden. Mit Vorteil können diese Bauteile durch eine oder mehrere innen und außen positionierte Erfassungseinrichtungen überprüft werden. Auch die Elektrik bzw. Elektronik, die sich in oder an den aufgezählten Fahrzeugteilen befindet, kann überprüft werden. Damit können zum Beispiel im Rahmen einer Abfahrtkontrolle alle relevanten Komponenten überprüft werden.The at least one component to be detected is preferably part of a body and/or part of a chassis and/or part of a drive and/or part of a connection system of the vehicle. The body or the structure can be a body shell (doors, hoods and top), a driver's cab, glazing, seals, door locks, windshield wiper system, lighting equipment, bumpers, instruments, seats, z. for any passengers, interior trim, heating and air conditioning, and one or more batteries. These components can be checked, for example, by optical sensors to damage such. B. deformations or cracks, or defective lighting equipment such. B. defective headlights or direction indicators to recognize. Heating and air conditioning, on the other hand, could be checked using infrared sensors, for example. The chassis includes a chassis, which is also referred to as a frame, rims, tires and wheels, wheel location, suspension, brakes and steering. For example, a visual check for damage is also possible for the components of the chassis. In addition, the temperature of individual components, in particular the brakes, can also be detected, for example, by an infrared sensor. The drive includes an engine, engine cooling, energy storage and torque converter with clutch and manual transmission. The connection technology includes one or more locking devices, such as door locks, load securing, trailer/semi-trailer operation and coupling. Here, for example, it can be checked whether doors or other locking devices are properly locked in order to prevent a load from being lost, for example due to falling or theft. The correct connection of trailers or the successful coupling can also be checked. These components can advantageously be checked by one or more detection devices positioned inside and outside. The electrics and electronics, too is in or on the listed vehicle parts can be checked. This means that all relevant components can be checked, for example, as part of a departure check.
Vorzugsweise ist die Erfassungseinrichtung dazu ausgelegt, den Zustand einer oder mehrerer Komponenten während einer Fahrt des Fahrzeugs überprüfen zu können. Damit können Probleme, wie defekte Komponenten oder auch Komponenten, die aufgrund eines fortgeschrittenen Verschleißes möglicherweise bald defekt sein können, erkannt werden. Insbesondere in Ermangelung eines Fahrers bei autonom fahrenden Fahrzeugen ist diese Möglichkeit, Komponenten auch während der Fahrt zu überwachen, hilfreich, um Unfälle zu vermeiden. Beispielsweise kann so die Temperatur der Bremsen mit einer Infrarotkamera überwacht werden. Insbesondere ist es auch denkbar, dass eine einzige bewegliche Infrarotkamera die Temperaturen aller Bremsen überwachen kann und somit mehrere einzelne Sensoren ersetzen kann. Auch können Schäden durch Umwelteinflüsse, wie beispielsweise Zusammenstöße mit anderen Fahrzeugen oder z. B. während eines Sturms auf das Fahrzeug fallende Teile, beispielsweise Äste oder Steine, schnell registriert werden.The detection device is preferably designed to be able to check the state of one or more components while the vehicle is driving. This allows problems such as defective components or components that may soon be defective due to advanced wear to be identified. Especially when there is no driver in autonomous vehicles, this option of monitoring components while driving is helpful in order to avoid accidents. For example, the temperature of the brakes can be monitored with an infrared camera. In particular, it is also conceivable that a single movable infrared camera can monitor the temperatures of all brakes and can thus replace several individual sensors. Damage caused by environmental influences, such as collisions with other vehicles or z. B. during a storm on the vehicle falling parts, such as branches or stones, are quickly registered.
Vorteilhaft kann der durch die Erfassungseinrichtung erfasste Datensatz in einer Speichereinrichtung speicherbar sein. Die Speichereinrichtung kann zum Beispiel auf magnetischer oder elektronischer Speicherung basieren. Denkbar sind unter anderem Festplattenlaufwerke oder Halbleiterspeicher, wie beispielsweise FlashSpeicher, Speicherkarten, USB-Sticks oder SSDs. Gespeicherte Daten können beispielsweise als Nachweis einer ordnungsgemäßen Abfahrtskontrolle und/oder des Zustands des Fahrzeugs bei Fahrtantritt dienen. Auch können gespeicherte Datensätze zum Abgleich mit neu aufgenommenen Datensätzen verwendet werden, um auf diese Weise zum Beispiel eine Veränderung der Komponenten, z. B. durch Verschleiß, registrieren zu können. Dadurch können reparaturbedürftige Komponenten rechtzeitig und vorteilhafterweise auch schon vor einem endgültigen Defekt ausgemacht werden.The data set recorded by the recording device can advantageously be storable in a storage device. The storage device can be based on magnetic or electronic storage, for example. Among other things, hard disk drives or semiconductor memories, such as flash memories, memory cards, USB sticks or SSDs, are conceivable. Stored data can be used, for example, as proof of a proper departure check and/or the condition of the vehicle at the start of the journey. Stored data sets can also be used to compare with newly recorded data sets, for example to change the components, e.g. B. by wear and tear to be able to register. As a result, components in need of repair can be identified in good time and advantageously even before a final defect occurs.
Bevorzugt umfasst das System eine Kommunikationseinrichtung, mittels der eine den Zustand einer Komponente betreffende Information an eine Zentrale übermittelbar ist. Dort können zum Beispiel Informationen über mehrere Fahrzeuge gesammelt und eventuell auch verarbeitet werden. Dadurch ist beispielsweise eine einfachere Organisation benötigter Reparaturen und/oder Ersatzteile möglich. Auch ist es denkbar, dass einem Fahrzeug basierend auf dem Zustand seiner überprüften Komponenten bei Bedarf neue Befehle, wie zum Beispiel das Abbrechen einer Fahrt und die Rückkehr in einen Fuhrpark oder in eine Reparaturwerkstatt übermittelt werden.The system preferably includes a communication device, by means of which information relating to the status of a component can be transmitted to a control center. There, for example, information about several vehicles can be collected and possibly also processed. This makes it easier to organize necessary repairs and/or spare parts, for example. It is also conceivable that, based on the condition of its checked components, a vehicle can be given new commands, such as stopping a journey and returning to a fleet or a repair shop.
Vorteilhafterweise steht die Kommunikationseinrichtung mit einem Netzwerk in Verbindung. Die Verbindung kann zum Beispiel über die Zentrale laufen. Alternativ ist es auch denkbar, dass die Kommunikationseinrichtung direkt mit einem Netzwerk in Verbindung steht. Zum Beispiel kann eine Verbindung mit einem stationären Hub oder eine direkte Verbindung mit anderen Fahrzeugen in der Umgebung hergestellt werden. Dadurch ist es zum Beispiel denkbar, dass bei Problemen einzelner oder mehrerer Komponenten eine Warnung an andere Fahrzeuge übermittelt wird, um Unfälle zu vermeiden. Probleme könnten zum Beispiel kurzfristig ausfallende oder nicht richtig funktionierende Bremsen, sich ungewollt öffnende Verschlusseinrichtungen (wodurch zum Beispiel Transportgüter herunterfallen könnten) oder eine defekte Anhängerkupplung sein. Über einen Hub könnte beispielsweise automatisch Kontakt zu einer Servicestation aufgenommen werden um z. B. Reparaturen anzufordern.The communication device is advantageously connected to a network. The connection can, for example, run via the central office. Alternatively, it is also conceivable that the communication device is directly connected to a network. For example, it can connect to a stationary hub or connect directly to other vehicles in the area. It is therefore conceivable, for example, that a warning is sent to other vehicles in the event of problems with one or more components in order to avoid accidents. Problems could be, for example, brakes that fail for a short time or do not work properly, locking devices that open unintentionally (which could cause goods to be transported, for example, to fall) or a defective trailer hitch. For example, a hub could be used to automatically contact a service station, e.g. B. Request repairs.
Vorzugsweise befindet sich die Erfassungseinrichtung während eines Ruhezustands zumindest teilweise, vorzugsweise vollständig, in einem abgeschlossenen Bereich. Ein abgeschlossener Bereich kann beispielsweise ein verschließbarer Behälter wie eine Kammer, eine Kapsel oder eine kleine Garage, die am Fahrzeug befestigt oder Teil des Fahrzeugs ist, sein. Auch ist eine Ausbuchtung am Fahrzeug möglich, in die zum Beispiel ein Schwenkarm, an dem eine Erfassungseinrichtung angebracht ist, im Ruhezustand abgesenkt wird. Optional kann die Ausbuchtung auch einen Verschlussmechanismus, wie eine Klappe oder einen Schiebe- oder Rotationsverschluss aufweisen. Durch den Aufenthalt in dem abgeschlossenen Bereich kann die Erfassungseinrichtung vor Umwelteinflüssen oder vor einem unbefugten Zugriff Dritter geschützt werden.The detection device is preferably located at least partially, preferably completely, in a closed area during an idle state. An enclosed area can be, for example, a lockable container such as a chamber, capsule, or small garage attached to or part of the vehicle. Also is a bulge possible on the vehicle, in which, for example, a swivel arm on which a detection device is attached is lowered when at rest. Optionally, the bulge can also have a closure mechanism, such as a flap or a sliding or rotating closure. By staying in the closed area, the detection device can be protected from environmental influences or from unauthorized access by third parties.

In
Das System eignet sich insbesondere zur Abfahrtskontrolle. Die Erfassungseinrichtungen 10 können vor und nach der Kontrolle jeweils über das Schienensystem 12 in jeweils vorgesehene abgeschlossenen Bereiche 11 fahren, um dort in einen Ruhezustand versetzt zu werden. Dadurch sind sie vor Umwelteinflüssen und vor unerwünschtem Zugriff unbefugter Personen geschützt. Es ist aber auch möglich, dass die Erfassungseinrichtungen 10 während der Fahrt fortwährend oder zeitweise zum Einsatz kommen. Zum Beispiel könnte eine Erfassungseinrichtung 10 an der Unterseite des Fahrzeugs 5 mit Hilfe einer Infrarotkamera die Temperatur der Bremsen überwachen. Durch die Mobilität genügt hierzu eine Erfassungseinrichtung 10 mit einem Sensor, die alle Bereiche mit Bremsen abdecken kann. Während so abwechselnd zwischen den Bremsen eine quasi kontinuierliche Überprüfung möglich ist, könnte die Erfassungseinrichtung 10 auch jeweils in bestimmten Zeitintervallen aktiv werden, wodurch Energie gespart werden kann. Allgemein ist auch ein System möglich, nachdem eine Erfassungseinrichtung 10 jeweils im Bedarfsfall aktiviert wird, um zum Beispiel bei Auftreten eines ungeklärten Problems die Ursache zu finden. So könnten zum Beispiel bei verschlechterter Bremsleistung gezielt die Bremsen, oder bei verschlechtertem Fahrverhalten die Reifen 4 und Achsen überprüft werden. Andererseits ist auch ein zusätzlicher Sensor denkbar, der bei ungünstigen äußeren Verhältnissen eine Aktivierung der Erfassungseinrichtungen 10 verhindert und sie dazu veranlasst, im abgeschlossenen Bereich 11 zu bleiben oder diesen aufzusuchen. Für einen optischen Sensor an der Unterseite des Fahrzeugs 5 könnten ungünstige Verhältnisse zum Beispiel ein schlammiger Untergrund sein, der zur Verschmutzung der Optik führen könnte.The system is particularly suitable for departure checks. Before and after the check, the
Bei dem hier dargestellten Fahrzeug 5 handelt es sich um einen Sattelzug mit einer Erfassungseinrichtungen 10, die an einer fliegenden Drohne 14 befestigt ist. Durch die große Mobilität kann in diesem Fall mit einer Erfassungseinrichtung 10 zumindest der komplette Außenbereich des Fahrzeugs 5 überprüft werden. Es ist denkbar, dass die Erfassungseinrichtung 10 über zwei oder mehr verschiedene Sensoren verfügt, um unterschiedliche Komponenten angemessen überprüfen zu können. Alternativ wäre auch eine fahrbare Drohne 14 möglich, die um das Fahrzeug 5 herumfährt oder auf dem Fahrzeug 5 fährt und auf diese Weise mehrere festgelegte Bereiche untersuchen kann. Auch ist optional eine weitere Drohne 14 im Inneren des Fahrzeugs 5 denkbar, die Komponenten in festgelegten Bereich im Inneren des Fahrzeugs 5 überprüft. Die Drohne 14 ist durch eine kabellose Verbindung mit einer Auswerteeinrichtung 20 im Fahrzeug 5 verbunden. Über die kabellose Verbindung können Informationen in Form eines Datensatzes 19, die beim Überprüfen der Komponenten gesammelt werden, übertragen werden. Zusätzlich oder alternativ kann auch eine direkte Verbindung zu einer Zentrale außerhalb des Fahrzeugs 5 bestehen. Die kabellose Verbindung kann beispielsweise auf WLAN, Bluetooth oder mobilem Internet basieren. Vorteilhafter Weise kann die Drohne 14 eine Überprüfung, wie beispielsweise eine Abfahrtskontrolle, vollständig autonom durchführen. Es ist aber auch denkbar, dass die Überprüfung ferngesteuert, zum Bespiel von der Zentrale aus, durchgeführt wird. Wenn die Drohne 14 nicht im Einsatz ist, befindet sie sich in dieser Ausführungsform in einem abgeschlossenen Bereich 11, der durch eine Klappe 11a verschlossen werden kann. Alternativ sind auch andere Verschlussmechanismen möglich, wie zum Beispiel ein Schiebedach. In dem abgeschlossenen Bereich 11 ist die Drohne 14 vor äußeren Einflüssen geschützt und es kann in einem Ruhezustand Energie gespart werden. In einer bevorzugten Ausführungsform befindet sich in dem abgeschlossenen Bereich eine Dockingstation, an der die Drohne 14, z. B. über einen elektrischen Anschluss, mit Energie aufgeladen werden kann. Auch ist optional ein Anschluss zur Datenübertragung möglich, an dem beispielsweise Updates für eine Systemsoftware der Drohne 14 übertragen werden können. Optional kann auch der erfasste Datensatz 19 über einen Datenanschluss übertragen werden. Dies kann zum Beispiel sinnvoll sein, wenn eine kabellose Übertragung nicht möglich oder nicht gewünscht ist. Insbesondere kann ein Datenanschluss auch eine alternative Option sein, für den Fall, dass die kabellose Übertragung ausfällt. In einer weiteren Ausführungsform kann die Drohne 14 auch zumindest zeitweise während einer Fahrt des Fahrzeugs 5 zum Einsatz kommen, um eine oder mehrere Komponenten an dem Fahrzeug 5 zu überprüfen.The

Das Fahrzeug 5 kann beispielsweise ein Nutzfahrzeug sein.The
Es umfasst eine Erfassungseinrichtung 10, welche sich an der Unterseite des Fahrzeugs 5 befindet. Die Erfassungseinrichtung 10 ist in diesem Beispiel über eine Drehachse 15b an einem teleskopierbaren Schwenkarm 15 befestigt. Der Schwenkarm 15 wiederum ist mittels einer Drehachse 15a drehbar an der Unterseite des Fahrzeugs 5 befestigt. Die Erfassungseinrichtung 10 umfasst beispielsweise einen Infrarotsensor, mit dem die Temperatur aller Bremsen erfasst werden kann. Dadurch ersetzt vorteilhafterweise ein einzelner Sensor mehrere Sensoren. Auch kann beispielsweise mit einer optischen Kamera das Reifenprofil überprüft werden oder es können Beschädigungen, wie beispielsweise Risse in der Bremsscheibe oder ein geplatzter Reifen, erkannt werden. In einem Ruhezustand wird der Schwenkarm 15 mit der Erfassungseinrichtung 10 in einer Ausbuchtung 110 versenkt. Optional kann die Ausbuchtung 110 einen Verschlussmechanismus, beispielsweise eine Schiebetür, umfassen. Dadurch wird die Erfassungseinrichtung 10 vor äußeren Einflüssen geschützt. Die Erfassungseinrichtung 10 kann beispielsweise bei Fahrtbeginn während einer Abfahrtskontrolle oder während eines Zwischenstopps eingesetzt werden. Optional ist auch ein Einsatz während einer Fahrt denkbar.It includes a
In einem zweiten Schritt wird dann der Datensatz 19 über eine kabellose Verbindung, alternativ auch über eine Kabelverbindung, einer Auswerteeinrichtung 20 bereitgestellt. Die Auswerteeinrichtung 20 stellt nun in einem dritten Schritt den Zustand der Komponente anhand des erfassten Datensatzes 19 fest. Die Auswerteeinrichtung umfasst beispielsweise einen Computer bzw. ein Mikroprozessor, der dazu ausgelegt ist, anhand des aufgenommen Datensatzes den Zustand der überprüften Komponente festzustellen. Der Datensatz kann nun in einem optionalen vierten Schritt auf einer Speichereinrichtung 30 gespeichert werden. Die Speichereinrichtung 30 kann beispielsweise eine Festplatte oder ein Flashspeicher sein. Die gespeicherten Daten können z. B. als Nachweis für eine durchgeführte Abfahrtskontrolle oder als Vergleich mit Daten, die zu einem späteren Zeitpunkt erfasst werden, dienen. In einem weiteren optionalen Schritt kann der Datensatz 19 an eine Kommunikationseinrichtung 40 weitergeleitet werden, die den Datensatz 19 z. B. an eine Zentrale übermittelt. Dadurch kann zum Beispiel eine Datenbank über mehrere Fahrzeuge 5 erstellt werden. Zudem können möglicherweise nötige Reparaturen zentral koordiniert werden.In a second step, the
