Definitions
- the invention is based on the object defined in the preamble of claim 1, which is no longer new in itself, cf. the older European patent application 90 116 107.5.
- the invention was initially developed for the airbag system of a motor vehicle. However, it was found that it is also much more generally applicable to other arrangements falling under the above-mentioned concept. Namely, the invention is e.g. Also suitable for roll bar and belt tensioner systems, not only for vehicles, but also for other vehicles, e.g. also for trucks, in principle even for airplanes.
- DE-A-22 63 845 discloses a circuit arrangement for recording a faulty operation of an occupant protection device by means of current pulse measurement (product of time and current strength), the occupant protection device containing an airbag, which is often referred to in specialist circles as an airbag.
- FIG. 3 shows an example of the course, namely the time-amplitude diagram, of the output signal of the first sensor that occurs in the event of an impact, which then emits a binary signal in this example.
- the circuit arrangement according to the invention is used to record important data in the programmable read-only memory P, which is also called PROM for short in specialist circles if the vehicle is involved in an impact.
- FIG. 1 thus shows an example of such a circuit arrangement, which here contains two sensors S and T and the control circuit E.
- the PROM P is installed in the latter.
- the circuit arrangement is to be installed in a vehicle which has an occupant protection device, e.g. has one or more airbags and / or belt tensioners and / or roll bars.
- this circuit arrangement In the event of a collision, this circuit arrangement emits a control pulse A at its output, which triggers the occupant protection system. Whether the circuit arrangement emits a control pulse A or not depends on whether at least two sensors are involved in the impact, cf. S, T, the trigger thresholds individually assigned to them, cf. y, w in Figures 2 and 3, exceeded in time.
- the terms "first" and "second” in connection with the sensors S, T are always defined here in such a way that, in the event of an impact, the output signal of the first sensor, here sensor T, rather than the output signal of the other, second sensor, see. S, which exceeds the trigger threshold individually assigned to them, cf. the triggering thresholds y shown in FIGS. 2 and 3 for the second and w for the first sensor.
- one of the two sensors starts, cf.
- the second sensor T called the clock-generating sensor T
- the first sensor must be at a point in time within this time period Z at the latest , e.g. S, as well as the second sensor, then T, have exceeded their trigger thresholds y or w so that the occupant protection system A is finally triggered. It may even be permitted that at least one of these sensors, e.g. T, before or at the beginning of the time period Z exceeded his individual trigger threshold.
- impact-relevant data about the behavior of at least one of the two sensors S, T, - generally about the behavior of both sensors S, T - are stored, specifically about their behavior at least during the time period Z defined by the clock-emitting sensor.
- a storage of data (at least via one of the two sensors) in the PROM P is provided according to the invention at least when both sensors exceeded their trigger threshold y, w at a point in time within this time period Z, so that the occupant protection system was finally triggered should be.
- the behavior of the sensors in the relevant period of time relevant to the triggering of the occupant protection system can be reliably recorded such that any later that after the impact the triggering the most important circumstances can be reconstructed.
- data on the behavior of the output signals of at least one of the two, if not additionally of the other, of the sensors S, T occurring during the time period Z is stored in the PROM P, if the sensor in question - or both sensors - is his / their trigger threshold y or w exceeded / exceeded.
- the behavior of the sensors S, T in the relevant time period Z which is relevant for triggering the occupant protection system, is recorded in such a way that their behavior, as well as the course of the impact itself, can be sufficiently reconstructed any time after the impact.
- the threshold value x of the clock-emitting sensor can be identical to its trigger threshold - cf. w - so that in the event of an impact the clocking sensor just exceeds its triggering threshold at the beginning of the time period Z that it has defined.
- the threshold value can be seen, cf. x in Figure 2, the clocking sensor - here the second sensor T i - smaller than its triggering threshold, cf. y, so that, in the event of an impact, the output signal of the clocking sensor exceeds its threshold value x significantly before its triggering threshold y is reached.
- one sensor can be used here in the For example, it is the first sensor S - choose a sensor which mechanically actuates a switch and which more or less delivers a binary output signal in the event of an impact, cf. OFF / ON in FIG. 3, that is to say switching a current or a voltage ON or OFF.
- the second sensor T - one can choose an electronic sensor, namely, for example, a piezoresistive or piezoelectric one, which delivers an analog output signal in the event of an impact.
- such data about the behavior of at least one of the two sensors S, T can be stored in the PROM P that after an impact they can both be seen at what point in time (1), cf. s or r, this sensor S and / or T exceeded its trigger threshold y or w, and also the amplitude, cf. 2 or ON in FIG. 3, of the output signal of this sensor S or T at further, other (i) times within the time period Z.
