Definitions
- the invention relates to a development of the control device specified in the preamble of claim 1.
- Control devices with these features have been known for a long time.
- a whole series of control units with these features have been developed for the control of airbag deployments.
- the invention is intended to ensure, before a trip, that the trip is not effected on the basis of a sensor output signal which does not correspond to an accident at all and that the accident may also be so severe that, despite the dangers associated with the trip and costs, triggering the system is justified.
- the object of the invention is therefore to improve or optimize the reliability of the control device. This object is achieved according to the invention by a control device which has the features specified in the main claim.
- the invention thus takes advantage of the fact that the time course of the sensor output signal strongly depends on the type of accident, e.g. whether it is a frontal or oblique impact. Especially in the initial phase of the accident, which is decisive for the evaluation, the time profiles of the sensor output signals differ more or less clearly from one another, as a result of which they draw a conclusion about the coming
- the temporal course of the sensor output signal or the sensor output signals is initially analyzed according to different criteria, each of these criteria being based on a mathematically differently defined threshold value.
- the final criterion for triggering the system is finally determined by logically linking the individual evaluation results.
- each of the evaluations is therefore dimensioned for a specific decision. This means that each individual evaluation can be optimized independently of the other evaluations to meet the specific requirements placed on them.
- the additional measures specified in the subclaims allow additional advantages to be achieved in each case. Among other things, allow the measures according to claim
- the invention and its developments are further explained using the exemplary embodiment shown in the figure.
- the example shown contains five separate evaluation circuits, each of which analyzes the course of the sensor output signal over time according to different criteria and thus according to a different definition of the threshold value - some of these evaluation circuits can even use several threshold values, e.g. a lower threshold value and an upper threshold value in order to allow window-like triggering conditions, which therefore correspond to a tolerance range.
- the exemplary embodiment shown in the figure has the following 5 parallel evaluation circuits: an evaluation circuit 1 in order to distinguish between accident-typical signal profiles of the sensor output signal and other types of sensor output signals; an evaluation circuit 2 to distinguish between the types of accidents frontal and oblique impact; an evaluation circuit 3 for determining whether the triggering threshold for a frontal impact has been exceeded; - To determine whether the trigger threshold for an oblique impact has been exceeded, an evaluation circuit 4; and to determine an optimal triggering time for the given system - taking into account empirically determined values of the occupant advance and the triggering dead time of the system - an evaluation circuit 5.
- the block "sensor signal” here contains at least one sensor, for example an electronic sensor, preferably with an analog output signal.
- This electronic sensor continuously measures the acceleration or deceleration at the installation location of the sensor in the vehicle.
- the sensor can be constructed as a piezoresistive sensor which emits an output voltage proportional to the acceleration or deceleration.
- the output signal of the sensor is amplified to such an extent that a meaningful work area results. Possible zero point fluctuations and other low-frequency interference are filtered out, for example, using a downstream bandpass filter contained in the block. tert. Prepared in this way, the output signal of the sensor can be transferred to the evaluation circuits 1 to 5 arranged in parallel. In the case of digital processing in these circuits 1 to 5, a conversion into the digital form can be carried out beforehand, for example still in the "sensor signal” block, using an analog / digital converter.
- Block 1 "accident detection” is the first evaluation circuit provided in the example. At its output, it generates an output signal that indicates the presence of an acceleration or deceleration curve that is typical of an accident. Traces of this type which are typical of an accident are generally sensor output signals which indicate negative accelerations, which also suddenly start, which are present over a certain time and which, however, do not have amplitudes which are too rapid. Sensor output signals that only indicate negative (or positive) accelerations for a short time are more likely to indicate an interference signal or a hammer blow or driving over a pothole and therefore must not activate the trigger circuit. Likewise, sensor output signals which very quickly assume a large amplitude are more likely to be e.g. an indication of damage in the sensor. The evaluation circuit 1 preferably carries out this check for features not typical of accidents by means of a whole series of differently defined threshold values.
- Block 2 “Frontal diagonal impact differentiation” is the second evaluation circuit attached in the example. It recognizes from typical, empirically ascertainable characteristics of the deceleration or acceleration course whether there is a frontal or an oblique impact of the vehicle. This distinction is necessary in order to implement different triggering thresholds of the restraint system or protective system for both types of accidents. This block 2 thus allows the different properties and risk of injury in both types of accidents to be taken into account.
- Block 2 could thus contain, for example, a bandpass filter with a downstream threshold switch with hysteresis.
- Block 3 "Triggering threshold frontal impact exceeded?" is the third evaluation circuit attached in the example. It examines the sensor output signal to determine whether the system's specific trigger threshold for a frontal impact was exceeded in the event of a crash.
- This threshold can e.g. be defined by the minimum speed of the vehicle immediately before the crash. If this minimum speed is not measured directly with the sensor or with one of the sensors, individual features of the acceleration or deceleration signal of the sensor during the crash can also be used to define the threshold value, even for estimating the speed before the crash become.
- Specifying a trigger threshold that is typical of an accident makes sense, since a trigger should only take place if it is really necessary. How severe a crash is can be e.g. recognize how high the deceleration or acceleration of the vehicle is and how long it lasted until then.
- the block 3 could therefore contain a threshold switch with a subsequent integrator.
- Block 4 "Threshold threshold diagonal impact exceeded?" is the fourth evaluation circuit attached in the example. It works analogously to the corresponding block 3 for the frontal impact, but takes into account the empirically ascertainable typical time profile in the event of an oblique impact, and therefore also the special vehicle properties in the event of an oblique impact. Because the evaluation results of blocks 3 and 4 are linked to the evaluation result of block 2 by means of AND gates 23 and 24, the example shown could be re-dimensioned into another variant according to the invention in that blocks 2, 3, 4 - and even the elements 23, 24 - form a single, correspondingly complex evaluation circuit which uses differently defined threshold values in order to carry out the same tests on the time profile of the sensor output signal.
- Block 5 is the fifth evaluation circuit shown in the example.
- the specific problem in determining the optimum ignition timing for the system is that the triggering should take place optimally a certain time (for example 30 ms) before the time at which the occupant has moved a certain distance from his normal sitting position .
- a deployed airbag e.g. takes a certain amount of time to inflate; only then can he effectively protect the occupant. A short time later, the airbag collapses again and loses its protective effect. The airbag should therefore not be fired too early, but also not too late, but rather in time so that the occupant falls into the airbag which has just been completely inflated.
- Block 5 thus checks e.g. on the basis of one or more threshold values assigned to it, whether it is already too late to trigger the system.
- block 5 should therefore have the ability to be able to draw conclusions about the future course from accelerations that have already occurred during a crash. This is possible if it is developed and optimized in such a way that the typical acceleration curve from crash tests recognizes it as correctly as possible.
- block 5 can process the signal according to the invention, for example, in such a way that it band-filters the sensor output signal and, for example, integrates it twice. In this way, a further signal can be generated, into which the band-filtered sensor output signal, the signal after the first, with different evaluation Integration and the signal after the second integration and is particularly well suited for vehicle-specific optimization of the triggering time of the system, the optimum triggering time being reached when a certain threshold value is reached.
- a further control unit for controlling the system can be distinguished from other types of accidents, e.g. a side impact, a rear impact or a free fall into an abyss.
- a side impact e.g. a side impact
- a rear impact e.g. a free fall into an abyss.
- the blocks 11, 31, 41, 51 "time window” serve to record a message about a detected event for a certain period of time, but also to limit this message in terms of time. It is thereby achieved that, in the event of a crash, several decisions of blocks 1 to 5 coincide correctly in time so that the system can be triggered via logic elements. On the other hand, it is also beneficial to delete signals in the time windows after a certain time so that no incorrect state is simulated.
- the relevant durations are to be selected more or less differently for each evaluation circuit, also depending on the vehicle type concerned.
- time window In order to show the importance of the time window, the following course can be pointed out:
- the vehicle is driving against an obstacle.
- the crash takes place, for example, in such a way that the vehicle is first slowed down slowly, with the occupant already shifting forward.
- the vehicle is then stopped abruptly by the obstacle.
- Known control units would now trigger the airbag because of the abruptness.
- the airbag should no longer be deployed, as this slammed into the face too late, at which point the occupant was no longer protected, but was only exposed to additional dangers.
- Such dangers can be avoided by means of the time window.
- the blocks "time windows" can each be realized by a monostable flip-flop, if only little effort is being sought.
- the "trigger circuit” block represents an electronic circuit that the system activates in the present example when one of the following two sets of conditions is met:
- the block "trigger circuit” can e.g. be an electronic circuit that conducts a sufficient current pulse through the squib of an airbag so that the squib fires.
- the parallel evaluation circuits 1 to 5 therefore generate binary output signals here.
- the 'true' state of the evaluation circuits 1, 3, 4, 5 favors or supports the triggering of the system in accordance with the above-mentioned 1st, 3rd and 4th requirements.
- Their signals are influenced by time circuits (timing elements) 11, 31, 41, 51 in such a way that a meaningful temporal overlap of the 'true' states of the individual signals can result. In detail, this can look like this, for example: - For evaluation after the 1st requirement:
- the 'true' state of the output signal of the evaluation circuit 1 is extended by the timer 11 in each case by a certain time, for example, so that shorter acceleration breaks or deceleration breaks are also bridged during an accident. This corresponds to the function of a switch-off delay.
- the evaluation circuits 3 or 4 and 5 will have the initial state 'true' for the entire further duration of the accident if the accident has a corresponding severity.
- the 'true' states can be limited in time by the downstream timing elements 31, 41, 51. This corresponds to the function of monostable flip-flops - the timing elements can e.g. contain such flip-flops.
- the evaluation after the 2nd request generates several output signals corresponding to the number of different types of accidents to be distinguished and thus according to the number of evaluation circuits after the 3rd request - here in the example shown in the figure, these numbers are two in each case.
- the output signals of the relevant evaluation circuit 2 release the output signals of one of the evaluation circuits 3 and 4 via the AND links 23, 24.
- the analog and logical functions written in a correspondingly digitized form can also be carried out using a memory-programmed computer, e.g. a microcomputer.
- the computer then forms all or at least some of the functions of the evaluation circuits, cf. 1 to 5, and possibly also their time window, cf. 11, 31, 41, 51 and the links 23, 24, 234, 12345, after.
