Definitions
- the invention relates to an arrangement according to the preamble of the main claim. It is based on a device according to the teaching of GB 2 046 914 A, according to which an analog measurement signal is digitized and fed to a memory arrangement consisting of several shift registers, the measured values being stored in each shift register at a different clock rate.
- a data acquisition device for the registration of driving data which should make the course of the accident verifiable by reconstructing the movement path of the vehicle, in particular with regard to accident situations for an objective clarification of the question of guilt, is essentially with two by the measurement signals of its sensors, which continuously record the driving dynamics of the vehicle significantly different waveforms.
- GB 2 055 469 A discloses an accident data memory as a ring memory, in which after detection of the standstill, a time delay is activated before the data storage is interrupted, for example to prevent the accident data storage from ending too early when the vehicle is moving with blocked wheels.
- the invention is based on the object of designing known arrangements for registering driving data in such a way that, taking into account the limited storage capacity, a high temporal resolution of the signal form of the analog measurement signal is ensured in the initial phase when an accident occurs.
- the solution according to the invention ensures that the data permanently read into the ring buffer with both frequencies ensures that the measurement signals of an accident situation are recorded with a high sampling rate as soon as they occur. No frequency jump is triggered by the accident detection.
- the selected memory controller also has the advantage that the data that were pending shortly before the accident event are also recorded with a high resolution. Since the storage of the measurement signals in the ring memory clocked with the higher frequency stopped immediately at the time of the accident detection the data stored over the loop duration is retained. This advantage in particular decisively improves the meaningfulness of the data recorded with the data acquisition device, since a reconstruction of the movement path of the vehicle is made possible much better by means of finely structured measurement data. Because it is precisely in the unambiguous, as complete as possible, showing the course of the accident that the purpose of this data recording is.
- an analog measurement signal 1 z. B. the longitudinal or lateral acceleration of the vehicle, plotted on the time axis 2, the ordinate 3 indicating the amount of the signal 1.
- the absolute value of the measurement signal is relatively small; the amplitude fluctuations are also relatively slow. If an accident now occurs, the magnitude of the measurement signal 1 changes abruptly, as a result of which a defined threshold 5 for triggering the memory controller according to the invention is exceeded and the accident event is recognized as such by the device.
- the accident detection can also include criteria and arithmetic operations which go beyond this simple threshold value exceeding.
- links to other sensor signals can also be used for accident detection.
- the memory controller according to the invention could also be operated manually by actuating an operating element, e.g. B. the hazard warning lights are triggered. It is crucial that the accident event is recognized as such and this detection triggers the sequence of the memory control according to the invention.
- the actual collision phase 7 is a part time of the accident recording time 6 and is recorded in addition to the normal data recording in the fast clocked data storage branch with high resolution.
- the higher-level accident recording time 6 ends either when the vehicle is at a standstill 10, characterized by the absence of the analog measurement signal 1, or after a specified follow-up time 9, which begins when the trigger signal 25 occurs.
- the accident record time 6, the total z. B. 45 seconds, is composed of a period 8 before the trigger signal 25 occurs and a follow-up time 9.
- a low-frequency sampling rate 11 (with the frequency f1) of the analog measuring signals 1 permanently detected by the sensory measuring device is sufficient for the data storage, since the storage of more measuring points 13 does not usably increase the information content.
- as many measuring points 13 as possible should be permanently stored at the higher sampling rate 12 predetermined by the frequency f2.
- Fig. 2 illustrates the memory control.
- Analog measuring signals 1 are continuously detected by the sensory measuring device of the data acquisition device and passed through an A / D converter 21. These digitized measurement signals are fed - either directly or combined with other time-synchronously acquired digital signals 20 into data words - to at least two ring memories 22 and 23 arranged in parallel, which read the data words in a different cycle.
- the respective clock frequencies f1 and f2, where f1 is the storage frequency for the ring buffer 22 and f2 for the ring buffer 23, are specified by a control unit 24.
- sampling frequencies f1 and f2 are different and should be selected so that f1 is suitable for sampling the low-frequency measurement signals of normal driving and that f2 is correspondingly higher in frequency in order to enable a high resolution of the high-frequency measurement signals which arise in accident situations. It has proven expedient to choose f1 at 25 Hz and f2 at 500 Hz.
- the control unit 24 triggers a trigger signal 25 which stops the continuous scanning and storage of the measurement signals in the ring memories 22 and 23.
- This stopping of the storage of the measurement signals in the ring memories 22 and 23 - and thus the preservation of the memory contents - takes place for both memories according to different criteria and at different times.
- the stopping of the storage in the ring memory 22, which stores the measurement signals at the lower frequency f1 is delayed so that the recording in this memory ends when the vehicle has come to a standstill 10 or at the latest after the specified follow-up time 9 has expired.
- This follow-up time 9 can be set at approximately 15 seconds to record what is happening after the actual accident.
- This storage takes place as long as the trigger signal 25 characterizing the accident situation is present. If the trigger signal 25 goes out, the memory 26 also ends the high-frequency data storage in the preferred embodiment with a time delay after a short follow-up time 14, for which 100 ms have proven to be sufficient.
- the recording duration of the memory 26 being composed of the duration of the trigger signal 25 corresponding to the collision phase 7 and a specified follow-up time 14.
- time periods 14 and 15 in FIG. 1 are correctly drawn in relation to the duration of the collision phase 7, but there are actually a large number of measuring points 13 in these time periods 14 and 15. In the preferred embodiment, there are approximately 50 measuring points each .
- This finely structured driving data can be assigned to the coarse grid of the data stored in the ring memory 22 such that when the trigger signal 25 occurs in both ring memories 22 and 23, the current time, if the data acquisition device is equipped with a real-time clock, or another suitable marking can be saved with.
- the stored data are evaluated later, it is possible to relate the two time patterns formed by the different sampling frequencies f1 and f2 to one another.
- the rapidly clocked data storage branch consisting of the ring memory 23 and the semiconductor memory 26, is executed multiple times in order to achieve several bumping events that occur within the follow-up time 9 that is assigned to the higher-level ring memory 22 and their duration in relation to the Follow-up time 9 are very short, to be able to record individually.
- Each new push process then activates the next parallel data storage branch as often as there is still a free data storage branch of this type.
