Definitions

  • FIG. 4 shows a vertical acceleration time diagram
  • the angle integrator with adaptive threshold values in order to optimize the integration.
  • FIG. 1 illustrates in a block diagram the device according to the invention.
  • a roll rate sensor DR is connected to an integrator 10 so that the roll rate can be integrated to a roll angle.
  • this integration is part of a microcontroller ⁇ C and is implemented in software. It is possible to arrange the integration outside the microcontroller ⁇ C in the control unit for controlling the personal protection means.
  • the roll rate sensor DR is a micromechanically formed sensor which is optimized for detecting the rotation rate.
  • the integration in the integrator 10 begins when the roll rate has exceeded a first threshold. It ends when it falls below a second threshold. Therefore, the second threshold is lower or identical to the first threshold.
  • FIG. 4 shows a corresponding time diagram for the vehicle vertical acceleration as a function of time. Again, the time t is shown on the abscissa and the vehicle vertical acceleration az is shown on the ordinate.
  • Curve 40 shows the vehicle vertical acceleration as a function of time. At time T4, the curve 40 exceeds the threshold value S4. That is, in the threshold control, it has now been found that the curve 40, that is, the vehicle vertical acceleration, is greater than the threshold value S4. Thus, the thresholds Sl and S2 can be reduced accordingly.
  • FIG. 5 shows a flow chart of the method according to the invention.
  • the roll rate is determined by means of the rotation rate sensor DR.
  • the vehicle acceleration and the vehicle vertical acceleration are determined by means of the acceleration sensors az and ay.
  • the roll rate is integrated.
  • the integration of the roll rate is determined after exceeding the roll rate of the threshold values Sl and S2. These are changed depending on the vehicle lateral acceleration and the vehicle vertical acceleration.
  • the resulting roll angle is checked in method step 503 with a triggering criterion, ie a threshold value, the roll angle is large enough and others triggers trigger conditions, then it comes to triggering in step 504 and thus to control the personal protection. If the roll angle is not large enough, then no triggering occurs and in method step 505 the method ends.

Abstract

L'invention concerne un dispositif et un procédé qui servent à déclencher des moyens de protection de personne et qui sont caractérisés en ce qu'un système de détection de taux de roulis (DR) génère un taux de roulis et en ce qu'un système de détection d'accélération détecte l'accélération transversale (ay) et l'accélération verticale (az). Un intégrateur (10) intègre le taux de roulis pour obtenir un angle, cet intégrateur commençant une intégration du taux de roulis lorsque le taux de roulis dépasse une première valeur de seuil et la terminant lorsque le taux de roulis devient inférieur à une deuxième valeur de seuil. En outre, un système de commande de valeur de seuil (SW) règle la première et/ou la deuxième valeur de seuil en fonction de l'accélération transversale et de l'accélération verticale. Un processeur commande des moyens de protection de personne en fonction de cet angle et d'autres critères.
