Definitions

  • the invention relates to an occupant protection control system with at least two occupant protection control devices for controlling two or more occupant protection systems in a vehicle (according to the preamble of claim 1).
  • the invention is particularly directed to an occupant protection control system containing at least two airbags, but also applicable to other types of occupant protection systems, for example rollover bar and / or belt tensioner systems.
  • the output signals emitted by crash sensors are continuously monitored.
  • the occupant protection system in particular the airbag, is activated.
  • these output signals emitted by the crash sensors are registered in a non-volatile memory, so that an accident data recorder is provided.
  • the output signals show in particular the speed curve and the decelerations of the vehicle for a certain period of time before the time of the accident until the accident itself, but can also provide important data, such as the lateral acceleration of the vehicle, for the course of the accident and thus for its reconstruction contain.
  • each of the control devices of these occupant protection systems can contain its own non-volatile memory, in which the accident-related parameters, such as speed and deceleration, measured by this control device, independently, in the event of an accident get saved.
  • This allows a better reconstruction of the course of the accident, since accident-relevant parameters measured by various control devices are then stored independently of one another, and additional statements about what is happening immediately before the accident are thus provided.
  • this poses the problem of the temporal correlation of the crash recordings in the later reconstruction attempt, since then the respective points in time of the data recordings may not be uniquely reconstructable and the timing of the accident-relevant data stored in the separate control devices is therefore problematic.
  • each control device is provided with a non-volatile memory, which increases the hardware complexity.
  • a known occupant protection control system (EP 0 693 404 A2) has two interconnected occupant protection control devices.
  • the invention has for its object to provide an occupant protection control system which enables a novel form of storage of accident-related data which facilitates accident data evaluation.
  • the invention also provides a method for operating an occupant protection control system which enables a novel form of recording accident-relevant data.
  • the data determined by another control unit and relevant to a possible accident are thus also stored in a control unit.
  • a further memory in addition to the non-volatile memory of this control device, there is preferably a further memory in which the signals generated by the sensor or sensors of the other control device can be stored.
  • the accident-relevant data determined by the control device containing the non-volatile memory stored in the non-volatile memory is stored in the non-volatile memory .
  • the occupant protection control system shown in the drawing as an exemplary embodiment is designed as an airbag system with a front airbag system 1 and a side airbag system 8.
  • the occupant protection control system shown in the drawing as an exemplary embodiment is designed as an airbag system with a front airbag system 1 and a side airbag system 8.
  • Front airbag system 1 - the associated control unit is preferably arranged centrally in the vehicle, for example on the vehicle tunnel - is used to control the deployment of the driver and / or front passenger airbag and contains an electronic control unit (processor) 2, which is used with sensors 6 (in particular, for impact detection) Speed and deceleration sensors) is connected.
  • the electronic control unit 2 is also connected via an internal bus system 3 (control, data and address bus) of the front airbag system 1 to a non-volatile memory 4 and to a further memory 5 designed as a ring memory.
  • the electronic control unit 2 monitors the sensor output signals in a known manner and triggers the ignition of the airbag when signals or signal curves signaling an impact are detected.
  • the electronic control unit 2 in the case of such an impact detection, also causes the sensor output signals to be stored in the non-volatile memory 4 in a known manner, so that the data characteristic of the course of the accident are stored permanently for a certain period of time before the actual time of the accident.
  • the non-volatile memory 4 can be designed as a programmable memory, for example as an EEPROM.
  • the memory 5 further provided according to the invention is designed as a volatile memory, for example as RAM, and stores the crash sensor signals supplied by the side airbag system 8 continuously (each for a certain period of time).
  • the side airbag system 8 - preferably arranged laterally in the vehicle - serves to control the deployment of the driver and / or front passenger side airbags and contains an electronic control unit (processor) 9 which is coupled to crash sensors 11, which are known in the art How to provide the information required to control the side airbag, for example regarding a side impact.
  • the output signal (s) of the sensor (s) 11 are also continuously on via an internal bus 12 (control, data and address bus) of the side airbag system 8 and a line 7 connecting the side airbag system 8 to the front airbag system 1 the front airbag system 1 directed.
  • the line 7 can be a specially provided line or can e.g. also be formed by the existing connection lines between the respective airbag systems and a central control unit.
  • the signals continuously output by the sensors 11 of the side airbag system 8 during the driving operation of the motor vehicle are stored in the memory 5 continuously (for a certain period of time) via the bus system 3.
  • the memory 5 thus saves the current output signals of the sensors 11 at this point in time and the data registered during a predetermined period before this current time.
  • the electronic control unit 2 detects an imminent or already occurring impact, it stores not only the data emitted by its own sensors 6 that characterize the course of the accident, but also the data contained in the memory 5 in the non-volatile memory.
  • the non-volatile memory 4 therefore contains the accident data of both the front airbag system 1 and the side airbag system 8 that are representative of the same time periods.
  • the electronic control unit can ensure that, in the event of an accident, in which possibly only the side airbag system 8 triggers the side airbag, but the front airbag is not activated, the data which characterize the side impact is permanently recorded 9 in such a case, supply the electronic control unit 2, for example via the connecting lines 7, 12, with a signal which signals the (impending) side impact.
  • the control unit 2 controls the re-storage of the data contained in the memory 5 into the non-volatile memory 4, in which it then optionally also processes the data from the sensors
  • the front airbag system 1 thus serves as an accident data recorder for the side airbag system 8.
  • No separate non-volatile memory is therefore required in the side airbag system 8.
  • the invention has been explained above using two airbag systems. However, the invention can also be used in conjunction with other occupant protection systems.
  • a belt tensioner control system and / or roll bar control system can be used, the accident-relevant data of which is then stored in the front airbag system or in another occupant protection system designed according to block 1.
  • the invention is particularly for use in

Abstract

Le système proposé de commande de protection des passagers présente deux appareils de commande, notamment un appareil de commande des airbags avant (1) et un appareil de commande des airbags latéraux (8). L'appareil de commande de protection des passagers comprend, outre une mémoire non-volatile (4), une mémoire supplémentaire (5) dans laquelle sont enregistrées en continu les données sous surveillance fournies par l'autre appareil de commande de protection des passagers pour détecter un éventuel accident. Lorsqu'un accident a été détecté, les données sont transférées de la mémoire supplémentaire dans la mémoire non-volatile, où sont également stockées durablement les données relatives aux accidents saisies par l'appareil de commande de protection des passagers.
