Definitions

  • Impact sensor consisting of at least two deformable hollow bodies and at least one pressure sensor
  • the invention relates to an impact sensor consisting of at least two deformable hollow bodies and at least one respective pressure sensor according to the preamble of claim 1 and a corresponding method for evaluation.
  • Such an impact sensor is known, for example, from EP 937612 A2.
  • the pressure measurement of the two sensors can be made plausible against one another and the position of the impact can be deduced from the transit time differences with respect to the two pressure sensors arranged on opposite sides of the vehicle.
  • the effort for assembly and wiring increases considerably.
  • impact sensors with a plurality of hollow bodies and a common pressure sensor are known, for example, from EP 1281582, whereby there is no longer any possibility of a plausibility check.
  • DE 10309713 A1 discloses an impact sensor unit in which two sensors sensitive to both pressure and acceleration are respectively arranged on opposite sides in the interior of the cavity.
  • a collision sensor unit can be seen, in which in each case a pressure sensor is arranged in each case in the interior of its own cavity.
  • the object of the present invention is therefore to present an impact sensor, which nevertheless allows a plausibility check with low assembly costs.
  • An essential idea of the invention is that the two pressure sensors are arranged in a common housing, that is to say a common electronic subassembly having a common circuit carrier, and sealed against one another in the housing, that is to say that for each pressure sensor a pressure supply area sealed against the other is provided. Due to the common housing, however, not only reduces the cost of this case, but also only one lead to evaluation needs and thus reduces the cost of installation and wiring.
  • Such impact sensors or at least their hollow bodies are integrated, for example, in the bumper in the front and possibly also at the rear of the rear and serve for impact detection for the release of pedestrian protection devices or occupant protection devices.
  • the pressure sensors are arranged on a common circuit carrier, so only one common circuit carrier is required. This, in turn, opens up the possibility of jointly using a common unit for supplying energy to the pressure sensors and / or a common unit for signal forwarding to an evaluation unit which can be connected to the impact sensor, for both pressure sensors, on this circuit carrier.
  • Figure 1 Sketch of a crash sensor according to the invention
  • FIG. 2 Sketching of an evaluation algorithm on the basis of these two sensors
  • FIG. 1 shows an impact sensor comprising at least two deformable hollow bodies 2. A and 2. B and at least one, in this exemplary embodiment, 2 pressure sensors 1 .2. A, 1. 1 b for detecting the pressure change in the respective hollow body.
  • These pressure sensors 1.2.a, 1.2.b are arranged in a common housing 1 and on a common circuit carrier 1 .1, wherein in the housing for each pressure sensor a sealed against the other pressure supply area 1 .3a, 1.3b is provided.
  • each hollow body 2.a and 2.b is separated from each other, the pressure supply areas are also 1 .3a, 1.3b separated from each other, for the specific embodiment of different possibilities, for example, a common partition between the two pressure supply areas is conceivable and Figure 1 in this regard, by no means as unique conceivable alternative to understand. Also in only one conceivable example, the conclusion 3 of the hollow body is shown on the opposite side of the housing. Thus, instead of a common end plug for both hollow body, a different separation may be provided, for example, the two hollow bodies are formed from a common tube, which then on this, the housing 1 opposite side by clamping means or other technical solutions in 2 pressure moderately separate hollow body is divided.
  • Such impact sensors or at least their hollow bodies are integrated, for example, in the bumper in the front and possibly also at the rear of the rear and serve for impact detection for the release of pedestrian protection devices or occupant protection devices.
  • a common unit for supplying energy to the pressure sensors 1 .2.a, 1.2.b as well as a common unit for signal forwarding to a connectable to the impact sensor on the circuit substrate 1.1 Evaluation unit 4 is provided.
  • a common unit for signal forwarding to a connectable to the impact sensor on the circuit substrate 1.1 Evaluation unit 4 is provided.
  • the two pressure sensors deliver the pressure signals p1 and p2. now the difference of the pressure
  • the pressure signal prel relevant to the algorithm On the basis of the pressure signal prel relevant to the algorithm, it is decided whether e.g. a pedestrian impact is present.
  • a pedestrian impact there are a number of parameters from the pressure signal, for example, the amplitude and duration of a pressure pulse.

Abstract

L'invention concerne un détecteur de collision comprenant au moins deux corps creux (2.a, 2.b) déformables et au moins un capteur de pression (1.2.a, 1.2.b) respectif pour capter un changement de pression dans le corps creux respectif, les capteurs de pression (1.2.a, 1.2.b) étant disposés dans un boîtier (1) commun sur un porte-circuit commun et une zone d'introduction de pression (1.3.a, 1.3b) étant prévue dans le boîtier (1) pour chaque capteur de pression (1.2.a, 1.2.b), ces zones étant étanches l'une par rapport à l'autre. Ce boîtier commun réduit la complexité du boîtier et une seule ligne conduisant à une unité d'évaluation est nécessaire, ce qui en simplifie le montage et le câblage. Ceci permet en outre d'utiliser sur le porte-circuit, en commun pour les deux capteurs de pression, une unité commune d'alimentation des capteurs de pression en énergie et/ou une unité commune de transmission de signaux à une unité d'évaluation pouvant être reliée au détecteur de collision.
