Definitions
- the invention relates to a vehicle module.
- the invention relates to a motor vehicle headlight, comprising a vehicle module according to the invention and a method for using a vehicle module according to the invention.
- vehicle modules To protect against the ingress of water, other environmental influences and manipulation from the outside, vehicle modules have closed housings to enclose the sensitive electronics of the vehicle modules.
- the electronics can be manipulated, for example, by opening the housing or by objects penetrating the housing. For example, tampering could occur by drilling an opening in a cover of the housing without lifting that cover of the housing.
- One object of the invention is therefore to create a vehicle module that reliably detects manipulations of different types.
- a vehicle module of the type mentioned at the beginning which according to the invention comprises a manipulation-detecting electronic control unit, the electronic control unit being set up to control at least one electrically controllable vehicle function, e.g. a light function, such as a low beam function or a high beam function, the electronic control unit includes:
- At least one circuit carrier in particular a printed circuit board, comprising an electrical circuit for carrying out the control by the electronic control unit
- a housing that at least partially encloses the circuit carrier comprising at least two parts, the circuit carrier being attached to a first part of the housing, and a second part of the housing being attachable to the first part in order to to at least partially close the housing and thus at least partially enclose the circuit carrier, and
- this monitoring system comprising the following:
- the electromagnetic monitoring signal being in a wavelength range between 230 nm and 30 m
- a receiving device for receiving the electromagnetic monitoring signal scattered within the volume to be monitored, the at least partially random distribution of the scattering material in the non-manipulated state being selected such that, based on a comparison of the emitted monitoring signal with the received signal scattered in the scattering medium, a Value of a module-specific fingerprint can be measured, this value representing a target value of a non-manipulated state, and
- a manipulation detection unit which is supplied with information about the module-specific fingerprint in the non-manipulated state, at least in the form of the target value, the manipulation detection unit being connected to the electrical circuit in order, by detecting the received actual state of the monitoring signal, to determine the actual value of the module-specific fingerprint, the manipulation detection unit being set up to compare the actual value and target value of the fingerprint and, depending on the result of the comparison, to conclude that the volume to be monitored has been manipulated.
- the transmitting device and/or receiving device can be formed without electrodes.
- the random distribution of the scattering medium can, on the one hand, be caused by a random spatial distribution of the scattering medium (ie during the process of introducing the scattering medium by hand or machine).
- scattering elements can also be arranged randomly within the scattering medium, so that a module-specific fingerprint can be measured.
- fingerprint does not mean a human fingerprint in this context. This expression is understood here as a synonym for at least one measured value that can be determined module-specifically and naturally varies from module to module. The invention makes it possible by expanding an already existing one electronic control unit to achieve a massive increase in the manipulation security of a vehicle module.
- the wavelength range of the electromagnetic monitoring signal is between 1000 nm and 230 nm. This enables monitoring in the optical wavelength range.
- the volume to be monitored between the housing and the circuit carrier is filled with a transparent medium that has randomly distributed scattering centers.
- a light signal can be produced by means of a laser or LED, for example.
- the light path can be influenced by the dispensed medium and only a certain part or only certain frequencies of the signal can be measured at the receiver (backward-operated LED, photodiode, camera).
- the housing is opened, the light distribution changes, which means that a break-in can be detected.
- the cheaper option here would be to use LEDs, especially SMD LEDs, since these can be easily attached to the printed circuit board with the current assembly processes.
- low-power LEDs rated current approx. 2mA
- the scattering material used is selected in such a way that it tears through the middle in the event of a break-in. This type of change has a much greater effect on the signal to be detected than would be the case if the stray material were to become detached from the housing or the circuit carrier.
- the scattering medium can be strategically placed on or in the vicinity of components that are particularly “worthy of protection”, or take up the entire interior space to be monitored.
- the transmitting device and/or the receiving device is in the vicinity of the components that are particularly “worthy of protection”. " is attached.
- lasers or LED light sources it can be provided that several light sources are used, which can emit light of different wavelengths, for example.
- LEDs in reverse operation for detection it can be provided that N*(N ⁇ 1) optical paths are measured with a number of N LEDs (where N is a natural number).
- An advantage of using reverse-powered LEDs for detection is the ability to measure different wavelengths, since LEDs cannot register light with a wavelength longer than their own. This can be advantageous if the medium introduced changes the wavelengths more significantly than the light paths, since the method mentioned allows a smaller number of optical paths to be measured compared to the variants mentioned above.
- the scattering medium comprises transparent material containing randomly distributed light-scattering scattering elements.
- the term "light-scattering” can be understood to mean both light-reflecting and/or at least partially absorbing properties. Refraction (due to entering a medium with a different refractive index) and diffraction effects are also relevant.
- the term "light-scattering” is therefore understood as an abstract term, which can include any kind of manipulation in which altered light is emitted.
- the change can also be, for example, in the wavelength, amplitude, phase, direction of propagation, etc. These can be realized, for example, by inclusions of air bubbles or reflective granules in the scattering medium.
- the following materials, for example, can be used as a scattering medium and/or scattering element:
- Transparent, hardening gel with granules as scattering centers Granules with a different refractive index are mixed into the gel. (e.g.: polycarbonate shredder; possibly also with different colors. This can occur when using different colored LEDs be particularly relevant).
- An advantage here is that this variant is mechanically particularly stable.
- a variant of epoxy resin with air pockets or also reflective granules can also be used here as a cost-effective variant.
- This resin can be transparent and yet sufficiently soft in the hardened state so that if the housing is opened it can tear or form a gap and thus not simply detach from the contact surfaces.
- a material that pulls strings Such a material would also significantly change the optical path and thus the detected signal.
- variations of synthetic rubber or special compositions based on resin come into consideration.
- the scattering medium is designed, arranged and connected to the second part and the circuit carrier in such a way that, if the second part lifts off the first part of the housing, the scattering medium tears into at least two separate material regions (i.e. without that the two material areas detach from the second part of the housing or the circuit carrier).
- the material pulls threads. As mentioned, such a material would significantly change the optical path and hence the detected signal.
- the transmission device for emitting the monitoring signal comprises an LED, in particular an SMD LED, or a laser light source.
- the receiving device can, for example, comprise a reverse-driven LED, a photodiode and/or a camera.
- the wavelength range of the electromagnetic monitoring signal is between 30 m and 1 m (related to the ambient medium air). This allows monitoring in a frequency range from 10 MHz to approx. 300 MHz. If a punctiform distribution of the scattering medium is desired due to criteria such as material saving, this would be possible if the fingerprint is implemented as an ohmic resistance, for example. As a result, it would have its own EM field (or an associated distribution of the field lines) and a destruction of its structure would have a significant impact on the value to be measured.
- the following materials can be used as a scattering medium or material used for the use of a monitoring signal in a wavelength range between 30m and lm:
- a material can be selected in which s r (relative electrical permittivity) and m G (relative magnetic permittivity) differ from air.
- s r relative electrical permittivity
- m G relative magnetic permittivity
- Another possibility is to use a foam with randomly distributed ferrite or metal chips.
- the conductive properties of the material are of course of great relevance. Then a material with a significantly higher electrical conductivity than air should be selected.
- any material whose influence on EM radiation is large enough to make destruction measurable is suitable.
- the scattering medium contacts the circuit carrier and the second part of the housing at points (mechanically and possibly electrically) and connects them to one another, with the scattering medium filling between 5% and 95% of the volume to be monitored.
- the radiation emitted by the electronic control unit in a target operation is used as a monitoring signal and thus the transmission device is formed by the electronic control unit, or the transmission device by a separate one from the electronic control unit High-frequency mixer is formed.
- target operation is understood to mean an operating state that is routinely provided and has the fulfillment of a target function of the electronic control unit as its object (e.g. the control of a light function). The emission of the monitoring signal takes place as a useful by-product due to the corresponding operation of the electronic control unit .
- target operation does not exclude the possibility that other desired operating states of the electronic control unit cannot be provided. This is merely at least one operating mode that can be selected from a large number of different target operating modes.
- high-frequency mixer is understood to mean a mixer that converts a specific frequency band into a lower or higher frequency band.
- the frequency of the mixture is determined by a local oscillator LO.
- the signal to be measured is the internal electromagnetic radiation of the ECU (which can be designed as part of the electronic control unit).
- the disadvantage of this variant is that the measured spectrum must be precisely defined here in order to avoid the measured signal being disturbed by external EM influences
- the operating state in which the measurement is carried out should also be precisely defined, since the operation of other assemblies can already cause a significant change in the measured signal.It would be advisable to consider a special frequency range in which the from external interfering signals min are imal.
- a printed line which serves as a receiving antenna, can be provided on the ECU circuit board.
- the output of the mixer should be connected to the CPU via one or two analog inputs. This enables the radio frequency amplitude received by the antenna and the associated phase to be determined over a certain frequency range.
- the realistic measuring range is between 100kH-5GHz.
- a frequency can be selected here which differs very significantly from the rest of the spectrum. This can be implemented either with an additional component or with the additional activation of an already existing component.
- a component is attached to the printed circuit board whose only task is to emit an electromagnetic signal at a specific point in time.
- the scattering medium has a dielectric constant s r and/or a permeability constant m G which deviates from the value 1 by at least 25%.
- the wavelength range of the electromagnetic monitoring signal is between 1 mm and 30 cm.
- monitoring can be carried out using radar signals.
- scattering centers should be chosen according to the wavelength of the radar. For example, this scattering center can only exist at one point in space. Materials that pull threads would be particularly suitable for this variant, as these can be better detected by the radar.
- the material is selected in such a way that the breakage can actually be detected for the wavelength of the radar.
- a radar chip for emitting a radar signal which is arranged on the circuit carrier and is in particular in the form of a component part of the electronic control device.
- radar alternative version which "scanning" the space into 2x2 dimensions can. This creates an image of the entire interior of the ECU, and the whole to be monitored volume. If the housing or the fingerprint to be deformed, this change is through the Radar detected. The intrusion is detected. This means that the radiation into space can take place at variable angles (e.g. in any direction within the opening angle of the radar chip), whereby a 2D image can be captured. A 3D -Image of the monitored volume can be calculated.
- the transmitting device and/or the receiving device are covered by the scattering medium, which extends in the area of coverage up to the second part of the housing.
- the scattering medium extends without gaps between the transmitting device and the receiving device.
- the transmitting device and the receiving device are spaced apart from one another and the volume to be monitored is located between the two devices, the distance between the two devices being at least 50%, preferably at least 75%, of the length of the circuit carrier.
- the expression "length of the circuit carrier” is understood to mean the longitudinal extent of a typically largely rectangular planar carrier. The length is greater than or at least equal to the width and extends as a straight line between two mutually parallel sides, with this straight line being oriented normal to the sides.
- the transmitting device and the receiving device are arranged at the same point on the circuit carrier. This can be beneficial when using a radar chip, for example.
- a material with high thermal conductivity can improve the thermal resistance R th
- the mechanical connection can be improved by using a material that has high vibration absorption.
- EMC electrochemical microparticles
- This can be, for example, materials that contain electrically conductive particles.
- This can be, for example, metal threads or flakes, graphite beads or flakes, carbon nano tubes or graphene flakes. If you want to use particles with high conductivity (metals) that are large enough that they could cause short circuits on the print in the treated state, you can also either the particles or the print are covered with an insulating layer (varnish, oxide layer, etc.). Ferrite particles or particles with ferroelectric properties such as barium titanate can also be considered.
- Materials that consist of mixing a base with scattering centers randomly distributed in it can also be processed space-filling.
- the monitoring system is set up to compare the recorded actual value of the fingerprint with the target value and, in the event of a deviation that is below a limit value, to store the recorded actual value as the new target value and use it for the next comparison.
- This limit value can be selected in such a way that a tolerance range is taken into account as a safety buffer and does not lead to erroneous tripping. As a result, signs of aging of the fingerprint can be taken into account.
- an upper limit can be provided for that value which is still technically conceivable as an age-related change. This upper limit can be, for example, a deviation of 10% from the target value. If the change exceeds this value, manipulation can be assumed, for example.
- a time component could also be taken into account and the limit value for the maximum change due to aging determined as a function of the time since the last start-up. Provision can thus be made for a change of less than 1% to be permissible given a time interval of just a few days, whereas larger changes are permissible given time intervals of months or years. Energy can be saved by measuring once, e.g. only during the starting process.
- an error routine can be initiated, which, for example, includes resetting to an operationally safe, predefined state.
- the invention also relates to a motor vehicle headlight, comprising a vehicle module according to the invention.
- the invention relates to a method for using a vehicle module according to the invention, with a basic setting procedure being carried out during the manufacturing and configuration process of the vehicle module, in which an initial fingerprint is determined and stored as a reference value in the vehicle module and in an external memory.
- the individual vehicle module can also be uniquely identified even later, based on the recording of the individual fingerprint, for example by comparison with a database.
- the limit value has a time component and increases with increasing time since the last start-up.

- the electronic control unit 1 is set up to control at least one electrically controllable vehicle function, e.g Control is carried out by the electronic control unit 1, a housing 3 which at least partially encloses the circuit carrier 2, the housing 3 comprising at least two parts 3a, 3b, the circuit carrier 2 being fastened to a first part 3a of the housing 3, and wherein a second part 3b of the housing 3 can be fastened to the first part 3a in order to at least partially close the housing 3 and thus at least partially enclose the circuit carrier 2, and a monitoring system 4 arranged on the circuit carrier 2 for detecting an intrusion into the housing 3.
- This monitoring system 4 comprises a transmission device 5a for emitting an electromagnetic monitoring signal U s into the volume V to be monitored enclosed by the housing 3, with the electromagnetic monitoring signal U s basically being in a wavelength range between 230 nm and 30 m, scattering material 6, which is in the at least partially distributed to be monitored volume V in unmanipulated state by accident, and is adapted to the emitted electromagnetic Letwachsungssignal U s to scatter, receiving means 5b for receiving the inside of the monitored volume V, scattered electromagnetic monitoring signal U s, wherein the in unmanipulated state at least partially random distribution of the scattering material is selected so that from a comparison of the output monitor signal U s with the received, scattered in the scattering medium signal U s', a value of a module-individual fingerprint FP messba r is, this value representing a target value S so u of a non-manipulated state, and a manipulation detection unit 7, the information on the module-specific Fingerprint FP are supplied in the non-manipulated state, at least in the form of the target value, with
- the monitoring signal U s is an optical signal, so that the wavelength range of the electromagnetic monitoring signal U s is between 1000 nm and 230 nm.
- the transmission device 5a for emitting the monitoring signal U s comprises an LED, in particular an SMD LED, or a laser light source.
- the receiving device 5b can be, for example, a reverse-operated LED, a photodiode or a camera.
- the transmitting device 5a and/or the receiving device 5b are covered by the scattering medium 6, which extends in the covering area up to the second housing part 3b.
- the scattering medium 6 comprises transparent material in which randomly distributed light-scattering scattering elements 6a are accommodated.
- the scattering medium 6 is arranged in such a way that it is connected to the second housing part 3b and also to the circuit carrier 2, so that if the second housing part 3b lifts off the first housing part 3a, the scattering medium 6 tears into at least two separate material regions (see also 6a to 7c).
- FIG. 2 shows a schematic representation of a second embodiment of the invention.
- the scattering medium 6 is not attached therein in the form of a continuous filling, but is formed by individual columnar connections which act on the circuit carrier 2 and the housing part 3b.
- the transmitting device 5a and the receiving device 5b are arranged at opposite ends of the circuit carrier 2 so that all of the components in between can be monitored, in that all of these components are surrounded by individual areas of the scattering medium 6 .
- the transmitting device 5a and/or the receiving device 5b are surrounded by air and the scattering medium 6 is at a distance from the transmitting device 5a and/or the receiving device 5b.
- the volume V to be monitored is located between the two devices 5a, 5b, the distance between the two devices being at least 50%, preferably at least 75%, of the length of the circuit carrier 2.
- FIG. 3a shows a schematic representation of a third embodiment of the invention, in which, for example, the positions of the transmitting and receiving device 5a and 5b are reversed compared to the first embodiment and the scattering medium 6 or scattering elements contained therein are selected so that the emitted Monitoring signal Us and the received monitoring signal Us 'for example, by the ratio of electric to magnetic field strength, differ from each other (see Fig. 3b and 3c).
- FIG. 3b shows an example representation of a transmitted monitoring signal, where x denotes the direction of propagation and the magnetic field strength H and the electric field strength E are shown, these field strengths being vectors. The cross product of these vectors represents the point vector, which represents the power flow of the electromagnetic signal.
- the scattering medium 6 or the scattering elements 6a can also be chosen such that the electric field strength decreases and the magnetic field strength increases.
- the total power flow can also be reduced by absorption or reflection along the propagation path. All of this information can be recorded by comparing the emitted signal Us and the received signal Us', as a result of which a module-specific fingerprint FP can be calculated.
- the scattering medium 6 can also be selected in such a way that it has an effect on the frequency or the frequency distribution of the received signal Us'.
- the sensitivity of the manipulation detection device can be additionally increased by specifically analyzing sensitive frequency ranges, in particular reference frequencies.
- Figure 4a shows a schematic representation of a fourth embodiment of the invention, in which, in contrast to the variants according to Fig. 1 to 2, no optical light beams, but electromagnetic signals in a frequency range between 10 MHz and 300 MHz are radiated.
- 4b shows the distribution of field lines around components 8 to be monitored in the form of dashed elliptical lines.
- the insertion of a plurality of reference symbols has been dispensed with.
- all of the components can be designed analogously to the variant according to FIG.
- FIG. 5 shows a plan view of a further embodiment of the invention, in which an exemplary spatial distribution of the scattering medium 6 along the two-dimensional plane of the circuit carrier 2 can be seen. Provision can be made for the monitoring signal Us that is emitted and the monitoring signal Us' that is received and is reflected here to be a radar signal.
- the transmitting device 5a and the receiving device 5b can, for example, be designed in one piece in the form of a single radar chip 5'.
- the radar chip 5 ′ is arranged on the circuit carrier 2 and, in particular, is embodied as a component part of the electronic control device 1 .
- FIGS. 6a to 6c show a scattering medium 6 in the applied state, namely before (FIG. 6a), during (FIG. 6b) and after manipulation (FIG. 6c). It can be seen how the scattering medium 6 tears when the cover 3b is lifted. Remounting the cover 3b or returning it to its original position (see FIG. 6c) also remains recognizable due to the change in the scattering medium 6, as a result of which a fingerprint FP associated with it was changed (namely towards the manipulated fingerprint FP′), this change can be detected as already described in detail and is used to determine the manipulation. This change in the fingerprint can also be seen from the change in an exemplary beam path LI (FIG. 6a) towards LI' (FIG. 6c).
- FIGS. 7a to 7c show a scattering medium 6 which pulls threads when a mechanical connection is released. As already mentioned, a manipulation of such a material can significantly change the optical path of the monitoring signal Us and thus the detected signal Us'. 7a also shows that a solder resist layer 9 can be formed on the surface of the circuit carrier 2.
- FIG. 7a shows that a solder resist layer 9 can be formed on the surface of the circuit carrier 2.
- the invention further relates to a motor vehicle headlight, not shown in the figures, comprising a vehicle module 10 according to the invention and a Method for using a vehicle module 10 according to the invention, wherein a basic setting procedure is carried out during the manufacturing and configuration process of the vehicle module 10, in which an initial fingerprint FP is determined and stored as a reference value in the vehicle module and an external memory.
