Definitions

  • the present invention relates to an adjustable restraint system for motor vehicles.
  • Known restraint systems that are used today have at least one crash sensor that generates a signal that indicates an impact and, if appropriate, its severity. This signal is processed in electronics so far that the relevant restraint components are triggered. Restraint components such as airbags, belt tensioners, knee protection pads, headrests that can be moved by an electric motor, etc. are mentioned here as examples.
  • crash sensor system In general, these systems have in common that a mechanical system is always controlled by the crash sensor system. This crash sensor system generates a signal which determines the further course of the reaction of the individual retention components. This is the classic case of a pure control, in which different sensors send their signals to an electronic module, which then determines the reaction of the individual restraint components.
  • the restraint system has at least one crash sensor, which generates a signal indicating an impact and possibly its severity, which is fed to further processing electronics, as well as a number of restraint components such as airbags, belt tensioners, knee pads and headrests which can be moved by an electric motor in each case at least one sensor, a state detection sensor, is assigned, which senses the state of this restraint component at least after the detected impact of the vehicle and after triggering the restraint component assigned to it, and generates a corresponding signal.
  • the condition detection sensor Signal is a control variable in control electronics compared with a specifiable setpoint for each restraint component as a control variable.
  • the respective restraint component is influenced by at least one actuator assigned to it in such a way that the signal generated by the condition detection sensor is brought up to the specific desired value.
  • condition detection sensors of the restraint components are force transducers, which detect the forces that arise between the latter and the vehicle occupant after activation of the respective restraint component, the load values thus detected being supplied to the control electronics as a control variable, which, depending on the deviation from the setpoint controls the respective actuator accordingly.
  • a predeterminable command variable can be software-fed into the control electronics using the same components for different vehicle types, depending on the vehicle type. This has the particular advantage that the same components can be used in a wide variety of motor vehicle types. Only the programming of the command variables then differs between the motor vehicles. It is therefore possible to use the same modules for all possible motor vehicles at low cost, with the corresponding cost advantage of using standardized components which can be produced in large quantities.
  • the reference variables can be stored in the control electronics. However, according to an advantageous further development, it is also possible to calculate the reference variables virtually online, to which the controlled variable must then be introduced.
  • the force to be applied in the event of an impact is determined from the position determination of the occupant and from further parameters such as, for example, the weight of the motor vehicle occupant for the respective restraint component.
  • This determined force is now used as the reference variable in the control process and is constantly compared with the signals generated by the state detection sensors. So there is virtually an online determination of the reference variable depending on the parameters mentioned. Then the continuously ascertained measured variables are processed accordingly by the state detection sensors in the electronics in order to control the relevant actuators, if necessary, and to adapt the controlled variable to the reference variable.
  • the embodiment can still be modified if a pre-crash sensor is advantageously used in the system.
  • the respective reversible restraint components such as electrically operated belt tensioners or headrests that can be moved by an electric motor, are brought into a preactivated state or into a starting position.
  • This embodiment is therefore primarily devoted to the pre-crash phase and prepares reversible restraint components for their use in the event of an impact that actually occurs. If this condition does not occur, it is possible to return the pre-activated restraint components to their original state without incurring any costs for restoring the restraint components, as is the case if the system is triggered incorrectly with non-reversible restraint components such as an airbag would.
  • the pre-crash sensor is calculated from the determined difference values between the speed of the vehicle, of which the sensor is part, and the obstacle, the energy to be absorbed by the respective restraint component , which is then used as the reference variable for the regulation.
  • the command variable is calculated in advance, i.e. before the impact occurs.
  • state detection sensors advantageously measure the deployment path of the airbag and a contact force between the vehicle occupant and the airbag after its ignition, the position of the vehicle occupant relative to the vehicle interior being determined and from the remaining one after the vehicle occupant comes into contact with the airbag Forward displacement to the dashboard of the vehicle is now calculated the force to be applied by the restraint system.
  • the reference variable is determined virtually online from the parameters that exist at the time the pre-crash sensor is activated.

Abstract

La présente invention concerne un dispositif de retenue réglable, destiné à des automobiles. Ce dispositif comprend au moins un détecteur d'impact, qui détecte une collision et génère un signal correspondant, ainsi qu'un certain nombre de composants de retenue, tels que des coussins gonflables, des prétendeurs de ceinture, des coussins de protection pour genoux et des appuie-têtes à déplacement électromotorisé, etc. Un détecteur de reconnaissance d'état, associé à chacun de ces composants de retenue, détecte, au moins après la collision du véhicule détectée, l'état des composants de retenue qui lui sont associés et génère un signal correspondant. Le signal produit par le détecteur de reconnaissance d'état sert de grandeur de réglage pour le traitement ultérieur, dans un système électronique de régulation, dans lequel la grandeur de réglage est comparée à une valeur théorique prédéfinie, spécifique à chaque composant de retenue, qui sert de valeur de référence.
