  • Patent number: 6456915
    Abstract: The invention relates to a method for operating an occupant safety device and a control unit for performing the method. To limit the power supplied to a triggering means from a storage element, the electrical power supplied after operating each triggering means is measured and after a definable power limiting value has been reached the power supplied to the triggering means is interrupted. The known methods based on the voltage at the storage element being the measure of the power supplied prove to be highly prone to error because these depend firstly on the charged state of the storage element and secondly very much on the conductor resistance so that incorrect control action can result.

  • Patent number: 6140821
    Abstract: The invention concerns a method for the recognition of insulation defects in a circuit adapted for connection to a low-ohmic current source or sink having off-load voltage U.sub.n0, Towards this end the circuit is initially subjected, in a separated state, to a diagnostic voltage from a current limited current source or sink whose off-load voltage U.sub.h0 corresponds to exceeds or, respectively, is less than the voltage U.sub.n0. A decision is made as to the presence or absence of an insulation defect based on the current and/or voltage dependence during application of the diagnostic voltage. Finally, in the event that a defect is present, an error message is issued and the low-ohmic current source or sink is not connected to the circuit for self-diagnosis. Otherwise, the low-ohmic current source is connected to the circuit, or the sink, in sequential fashion for self-diagnosis testing. In this fashion even hidden insulation defects are recognized.

  • Patent number: 5726887
    Abstract: This invention concerns a test procedure for a safety system in motor vehicles, in particular occupant protection devices such as airbag, belt tightener, or roll bar sensors. As a rule, the associated safety-critical circuit components of such safety systems will be monitored by additional and separate monitoring processors. According to this invention, a test procedure for these safety-critical circuit components requires little expense and which, using a simple-to-implement monitoring unit, will allow the same test quality to be achieved as with an independent monitoring computer.

  • Patent number: 5712784
    Abstract: A trigger circuit for occupant protection systems in motor vehicles comprises a control unit which will effect the triggering of a means of restraint such as an airbag, depending on sensor signals generated by one or more external sensor units. To achieve a degree of triggering certainty, data interrogation must take place in very short time intervals. A safe transmission of data between the control unit and the sensor units will be ensured if, in accordance with this invention, the information units to be transmitted will each be encoded by means of a PWM signal with a certain period duration. The control unit will check the period duration of the PWM signal received, and, in the event of this actual period duration not matching the specified nominal value, it will not accept the relevant unit of information.

  • Patent number: 5696776
    Abstract: A data transmission method in a real-time data processing system, comprising a control unit and at least one function unit linked to this control unit through a data line, is described that permits noise-free and noise-insensitive transmission of data. In accordance with the invention, the data is stored in a buffer memory made up of a shift register and an intermediate storage, before being loaded into a main memory of the function unit. Transfer to the intermediate storage takes place only if certain conditions are satisfied that identify transmission faults. Before the data is stored in the main memory, the data is read-back into the control unit memory for the purposes of checking and there it is compared with the original data. If there is no correspondence, data transmission is performed again.

  • Patent number: 5608628
    Abstract: A method and apparatus for recognizing a crash, in a vehicle by measuring vehicle speed change continuously within a limited time periods and comparing the measured values with those determined in prior time periods. Acceleration can be differentiated out by means of the above-mentioned process/arrangement and can be evaluated if, in the case of a high-speed and low-speed crash, it should not be possible to differentiate sufficiently by means of the partial speed difference. Different partial speed differences (by means of observation periods of different durations) can be measured and compared in order to permit ignition in the case of slower (oblique) crashes only within a limited time window in the initial phase of the crash.
