Definitions
- the invention relates to a method for analyzing and evaluating a signal according to the preamble of claim 1 and a corresponding device according to claim 15. Furthermore, the invention relates to a control device for an occupant protection system of a vehicle according to the preamble of claim 21.
- the Fourier transform transforms a periodic signal into simple, periodic sine waves of different frequency and amplitude, i.e. broken down into its basic components.
- a complex signal such as the signal from a sensor
- the Fourier transformation does not allow an analysis of the temporal occurrence of different spectral signal components.
- the Fourier transformation would have to be applied to different time windows of a signal.
- the selection of the time window is critical, particularly in the case of rapidly changing sensor signals, such as those generated by acceleration sensors of occupant protection systems in automobiles in the event of a crash.
- wavelets With a wavelet transformation or decomposition, on the other hand, a signal is limited in time, i.e. finally broken down signal elements that are long and contain only very few vibrations, which are referred to as wavelets.
- US 6 182 035 describes a detector for voice activities in which an audio signal through a plurality of filters, the orthonormal wavelet Have coefficients is transformed. An evaluation of the output signals of the different filters enables the recognition of voice activities.
- the wavelet transformation is implemented here by hardware implementation of various high and low pass filters.
- No. 5,826,232 describes a method for speech synthesis based on an orthogonal wavelet transformation, in which an audio signal is digitized, transformed on the basis of orthogonal wavelets, stored and restored for output from the coefficients of the wavelet transformation.
- the wavelet transformation In contrast to the Fourier transformation, the wavelet transformation also allows a statement about the temporal course of spectral signal components and is suitable, for example, for analyzing the changes over time in frequency components of an acceleration sensor signal of an occupant protection system.
- the use of wavelet decomposition in occupant protection systems has been extensively described in the prior art, see e.g. DE 100 12434 A1, DE 196 11 973 A1, DE 100 42 376 C1, EP 1 101 657 A2 or DE 197 13 087 A1. However, it requires high computing power and therefore requires digital signal processors for implementation.
- the object of the present invention is therefore to propose a method and a device for analyzing and evaluating a signal, in particular a sensor signal, which require low computing power and can therefore be implemented inexpensively , Furthermore, a control device for an occupant protection system of a vehicle is to be proposed which has a triggering behavior that is better adapted to a crash.
- An essential idea of the invention consists in transforming a signal for analysis by means of an orthogonal decomposition into basic functions of low order or a method equivalent to it in order to obtain criteria for an evaluation of the signal. Since a complete transformation of the time domain into the frequency domain is often not necessary, since only certain frequency bands are to be monitored with regard to their changes, a complete decomposition of the signal can be omitted or a decomposition into basic functions of low order can be sufficient. This type of signal analysis can be carried out with less computation effort than a complete discrete Fourier or a wavelet transformation and is therefore particularly suitable for analyzing signals from acceleration sensors of a vehicle occupant protection system. Put simply, the invention proposes an incomplete decomposition instead of a complete transformation of the signal, that is, an orthogonal decomposition into basic functions of low order.
- a further advantage of the invention consists in the fact that the orthogonal division into frequency components automatically causes the integral components of a signal to fall off as a by-product and can be further processed, for example, in an occupant protection system
- the invention now relates specifically to a method for analyzing and evaluating a signal, in particular a sensor signal.
- the signal is processed by orthogonal decomposition into basic functions of low order or to this equivalent method in order to obtain criteria for the evaluation of the signal.
- the orthogonal decomposition into basic functions of low order or this equivalent method within a time window of the signal enables coefficients of the decomposition to be determined and used for the evaluation of the signal.
- the computational effort can be further reduced since only a certain number of signal values have to be processed in the case of digital processing on signal samples.
- One or more linear combinations of a basic function of the coefficients of the decomposition, in particular their absolute amounts or a function of their absolute amounts, are preferably determined and used to form evaluation criteria for oscillations or vibrations in acceleration signals. As will be explained in the following, it has been shown that, for example, to reliably differentiate between different crash situations in vehicles, a detection of oscillations or vibrations in certain
- At least one criterion can be obtained from an incomplete orthogonal decomposition of the signal; that quantifies the oscillations or vibrations contained in the signal.
- the orthogonal decomposition of the signal can be continued until a complete decomposition in order to quantify oscillations or vibrations over the entire frequency range if this would be necessary, for example, to trigger an occupant protection system.
- the signal is generated by an acceleration sensor of an occupant protection system of a vehicle and the at least one criterion is used to form or influence an increase or decrease value for trigger integrals or trigger thresholds of the occupant protection system.
- the signal is broken down into a linear combination of orthogonal basic functions of a low order, and criteria for evaluating oscillations and / or vibrations in the signal are generated on the basis of the breaking down.
- the decomposition is preferably carried out dynamically, in a window which shifts over the time profile of the signal, in order to always process current signal values with limited computing effort.
- the signal can be broken down, for example, using a standard orthogonalization method, in particular using the Gram-Schmidt method, or using methods or schemes adapted to the orthogonal basic functions.
- One or more criteria can then be formed from the absolute values of the decomposition, which are used for evaluating oscillations and / or vibrations in the signal.
- the sensor signal is preferably an acceleration sensor signal and from the acceleration values contained in the signal, parameters are continuously determined as the criteria that quantify the vibration behavior of the signal within a time window.
- acceleration-related trigger thresholds or Trigger integrals of the occupant protection system are then preferably used to generate or adapt acceleration-related trigger thresholds or Trigger integrals of the occupant protection system are used to improve the triggering behavior of the occupant protection system.
- the method according to the invention comprises the decomposition of a data stream ⁇ a representing the signal into a countable number of orthogonal basic functions ⁇ h ie I, which are compared to an inner product ⁇ •, •> on the space of all sequences ⁇ b ⁇ or on the space of all episodes ⁇ brj- with b ⁇ O for at most a finite number
- n are orthogonal , j ⁇ i
- the orthogonal basic functions ⁇ ⁇ can be selected so that they describe basic information to be extracted from the signal.
- coefficients et, - of the development can be weighted and evaluated as parameters for controlling or influencing a triggering decision of an occupant protection system which is designed to process the signal.
- the invention further relates to a device for analyzing and evaluating a signal, in particular a sensor signal, with a microprocessor and a memory.
- the microprocessor is set up or programmed in terms of program technology in order to process the signal by orthogonal decomposition into basic functions of low order or to this equivalent method in order to obtain criteria for evaluating the signal.
- the microprocessor is programmed or programmed to determine the coefficients of the decomposition within a time window of the signal by the orthogonal decomposition into basic functions of low order or to this equivalent method and to use them for evaluating the signal.
- the microprocessor can also be programmed or programmed to determine one or more linear combinations of a basic function of the coefficients of the decomposition, in particular their absolute amounts or a function of their absolute amounts, and to use them to form evaluation criteria for oscillations or vibrations in acceleration signals.
- the microprocessor is set up or programmed in terms of programming in order to obtain at least one criterion from an incomplete orthogonal decomposition of the signal; that the oscillations or
- Vibrations quantified can also be programmed in such a way that the orthogonal decomposition of the signal is continued until it is completely decomposed if a quantification of oscillations or oscillations over the entire frequency range is necessary.
- Microprocessor to be set up or programmed in terms of program technology in order to process the signal generated by an acceleration sensor of a vehicle occupant protection system and to use the at least one criterion to form or influence an increase or decrease value for trigger integrals or trigger thresholds of the occupant protection system.
- the invention relates to a control device for a vehicle occupant protection system, which is characterized in that it has a device according to the invention and as explained above. Further advantages and possible uses of the present invention result from the following description in conjunction with the exemplary embodiments illustrated in the drawings.
- 1 shows a diagram with qualitative profiles of acceleration sensor signals in two collisions, each with different vehicle and impact speeds
- FIG. 2 shows the qualitative course of the speed loss in each of the two collisions of FIG. 1;
- FIG. 3 shows a structure of a device for processing the signal of an acceleration sensor of an occupant protection device of a motor vehicle by orthogonal decomposition according to the invention
- FIG. 4 shows a diagram with an example of an orthogonal decomposition of an acceleration sensor signal in a first collision at high speed
- FIG. 5 shows a diagram with an example of an orthogonal decomposition of an acceleration sensor signal in a second collision at low speed
- FIGS. 4 and 5 shows the section integrals of the acceleration signal profiles of the two collisions of FIGS. 4 and 5; 7 shows an embodiment of a device for analyzing acceleration sensor signals according to the invention
- FIG. 8 shows a flow chart of a first exemplary embodiment of the method according to the invention.
- FIG. 9 shows a flowchart of a second exemplary embodiment of the method according to the invention for analyzing an acceleration sensor signal
- devices and methods which measure safety-relevant acceleration-dependent values, for example the current acceleration, the acceleration integral or the speed change in a vehicle.
- Trigger integrals compared with threshold values for triggering, so-called trigger or trigger thresholds.
- trigger or trigger thresholds Trigger integrals compared with threshold values for triggering, so-called trigger or trigger thresholds.
- triggering by a simple comparison with a trigger or trigger threshold has the disadvantage that it is not equally well suited for all accident scenarios. In other words, there may be accident scenarios in which a crash signature, that is to say the signals from acceleration and / or crash sensors, indicate a triggering, since the predetermined triggering or trigger thresholds are exceeded, but actually no triggering is necessary.
- this problem is now solved using a trigger crash at a speed of 40 km / h, which was driven with 40% coverage against a deformable barrier (ODB), and using a non-trigger attempt at a speed of 15 km / h explained against the rigid wall.
- ODB deformable barrier
- FIG. 1 shows the course of the signal of an acceleration sensor of an occupant protection system of a vehicle, once for the event of a trigger crash (reference number 10) and the other time for the case of a non-trigger attempt (reference number 12). It can be seen from the temporal profile of the sensor signal shown in FIG. 1 that the signal profile 10 has relatively strong oscillation components during the triggering crash. In contrast, the signal curve 12 has only weak or no oscillation components at all in the non-triggering attempt.
- Oscillations through an analysis of the acceleration sensor signal can therefore provide valuable information for triggering an occupant protection system.
- the acceleration (sensor) signals are broken down into a linear combination of orthogonal basic functions.
- This decomposition does not take place rigidly, ie based on the entire acceleration signal, but dynamically; ie in a window shifting over time.
- This type of orthogonal decomposition is referred to as sliding orthogonal decomposition.
- the absolute values of the coefficients of this decomposition quantify the extent to which the vibration structure corresponding to the orthogonal base function in the corresponding frequency band enters the acceleration signal within the window.
- one or more criteria can be formed from the absolute values of the decomposition coefficients, for example by summing or forming a window integral; that can be used to evaluate oscillations and influence triggering decisions.
- An evaluation algorithm of a system for occupant protection is one or more sensor signals in the form of a discrete
- This can be, for example, accelerations, pressures, changes in speed in a time window or variables derived from them, such as mean values;
- the method according to the invention now comprises the decomposition of the data stream ⁇ a n ⁇ into countably many basic functions ⁇ “ie /, which are compared to an inner product ⁇ •, •> on the space of all sequences ⁇ b or on the space of all sequences ⁇ bn ⁇ with b ⁇ 0 for at most finitely many n are orthogonal
- Z denotes the set of integers. Because of (1), the coefficients have a simple representation
- the orthogonal basic functions ⁇ are now selected so that they describe basic information to be extracted from the signal. Then the coefficients a, - indicate the extent to which the associated basic information is contained in the signal ⁇ a n ⁇ .
- the decomposition of the signal can, for example, but not limited by standard Orthogonalmaschinesmethoden (eg Gram-Schmidt method) or the basic functions adapted effective methods or schemes carried ,
- the bilinear form becomes the inner product
- the coefficients are special signal mean values of an appropriate order. For use in real-time applications of triggering algorithms in occupant protection, this allows simple schemes for the calculation of the coefficients.
- the coefficients c, - ⁇ (a), k ⁇ 0, ie 2 k + 1 Z, describe the unambiguous proportion of the building blocks of the form ⁇ ⁇ in the signal a. This part is localized to the time window [i, i - 2 k + 1 + 1].
- a quantity for evaluating the proportion of these signal components of a fixed order can be, for example, a local L 1 standard
- the residues R p (a, -) describe the constant components of the order ⁇ p after factoring out the decompositions of the lower order.
- the decomposition does not have to be carried out completely to evaluate the signal components; but only in the considered time window up to the considered order.
- the breakdown into orthogonal signal modules is clear, ie information redundancy does not occur.
- the decomposition into orthogonal signal modules is reversible, ie the signal can be completely reconstructed from the coefficients or from the coefficients up to a given order and the rest using an efficient method.
- a time window [i, i-2 k + 1 +1] is first selected in a step S2, for which the orthogonal decomposition of the discrete signal ⁇ a, ⁇ is to be carried out.
- the coefficients C k (a) in the time window are calculated in a subsequent step S4 in accordance with the equation given above.
- a step S4 either a local L1 norm or another function is formed from the coefficients c ⁇ a) calculated in the time window.
- the proportion of the oscillations or vibrations in the signal a is evaluated on the basis of the norm or other function formed.
- FIG. 3 A structure of the method described below is shown in FIG. 3.
- FIG. 9 A corresponding flow chart is shown in FIG. 9.
- step S6 Given a sequence of acceleration values 18, which are available as a digital signal to a crash classification algorithm (step S6).
- the duty cycle of these acceleration values is e.g. about 1 ms, about 0.5 ms or about 0.25 ms.
- the present method is independent of this duty cycle.
- m 2 m is selected as the window length for the analysis (step S7).
- m 3
- m 4
- m 5
- m 6.
- m corresponds to the order of the basic function up to that the signal is broken down.
- the method presented below is independent of the special value for m.
- Window integrals of different window lengths: They form the homokinetic components, so to speak, which are split off from the frequency components during the analysis.
- a second step criteria for quantifying the vibrations are developed from the amounts ⁇ c [l, s] (n) ⁇ (step S15 in FIG. 9 and steps S151 to S155 in FIG. 10). Among other things, it offers weighted means
- window integrals the temporal development of the oscillations are recorded in more detail (steps S153 and S154). These window integrals over the quantities s (n) can, for example, be added as evaluations to trigger integrals (step S155), in order to accelerate a release of the restraint means (belt tensioners, airbags, in the event of frequent oscillations in trigger crashes (such as ODB, pile or underride tests) ) or slow down (belt force limiter). However, compared to thresholds, they can also be used to switch conventional trigger thresholds up or down.
- the restraint means belt tensioners, airbags, in the event of frequent oscillations in trigger crashes (such as ODB, pile or underride tests)
- slow down belt force limiter
- Order of magnitude (eg in LSB) as the result of an orthogonal decomposition of a typical ODB trigger attempt (FIG. 4) and a typical non-trigger attempt (FIG. 5).
- the graphs are of each three coefficients as a function of time, ie three curves are shown.
- the oscillations that occur in the ODB trigger attempt generate significantly more value of the coefficients than in the non-trigger attempt.
- the section integrals 20 and 22 diverge so clearly from a point of time of about 6 ms that a reliable distinction between the ODB trigger attempt and the non-trigger attempt is possible.
- FIG. 7 shows a possible implementation of the invention in a control device for an occupant protection system for a motor vehicle, such as a passenger car.
- Two acceleration sensors 24 and 26 are provided in the control unit for measuring accelerations which occur in the event of a crash of the motor vehicle with an object.
- Analog-to-digital converters 28 and 30 are connected downstream of the acceleration sensors, which sample and digitize generated analog signals from acceleration sensors 24 and 26 at a predetermined clock rate.
- the digitized sensor signals as sequences ⁇ a n ⁇ of acceleration values are then transferred for further processing to a microprocessor 32 in the control unit.
- the microprocessor can be a commercially available processor as used in control units for occupant protection systems.
- the processor 32 executes a program which implements the method according to the invention and is stored in a memory 34, for example a ROM or a programmable memory such as an EEPROM or Flash PROM.
- the memory 34 also contains the above-mentioned dyadic numbers b [k, s], which are calibrated to the motor vehicle.
- the microprocessor 32 generates a trigger signal 36 for protective devices such as, for example, airbags, automatic belt tensioners or similar restraint devices.
- the microprocessor 32 in particular implements the structure shown in FIG. 3.
- orthogonal basic functions according to equation (2) An extension of the method explained here on the basis of the orthogonal basic functions according to equation (2) consists in the use of other basic function types, which factor other signal modules from the signal and lead to other formulas for the calculation of the corresponding coefficients, to which the methods presented above generate of criteria can be applied.
- the orthogonal basic functions used for this purpose should be kept as simple as possible and, if possible, have a finite range of values from dyadic numbers.
