  • Patent number: 7421366
    Abstract: A bus station for connection to a bus system for a restraining device and/or sensor is used for muting a defective bus station or to have automatic error management carried out in the bus station, to enable the bus station to transmit properly again. For this purpose, the transmitting current and/or the power consumption of the bus station is monitored. The transmitting stage is triggered and, if appropriate, isolated from the bus station as a function of this monitoring. In a refinement a backup transmitting stage may be connected as a replacement for the defective transmitting stage.

  • Patent number: 7400641
    Abstract: A bus master for a bus for connection of sensors and/or an ignition means device, which has at least two bus driver arrangements allowing data to be received independently of one another. For this purpose a polling operation, specifically using a multiplexer or a demodulator associated through one of the particular bus driver arrangements, is used. Furthermore, a state machine is provided, which also alternatingly determines the system status on the basis of the measured quantities determined on the bus conductor for the particular bus driver arrangement. In a refinement, a particular bus driver may have a dedicated processor for system status determination.

  • Publication number: 20070100525
    Abstract: A safety apparatus for a motor vehicle, comprising: a plurality of occupant protection devices and sensors associated with them; a processing device that checks whether the occupant protection devices and/or associated sensors are in operation and/or properly functional, and ascertains status information therefrom; and an output device that, in consideration of all the status information, communicates the operating status possessed by each individual occupant protection device and/or sensor. Also described is a method for communicating the status of a safety apparatus of a motor vehicle.

  • Patent number: 7176587
    Abstract: A sensor adapted for connection to a bus and a method for supplying power to a sensor connected to a bus are described, which serve to minimize the power consumption of a sensor connected to the bus. To this end, power for a sensor is stored in an energy storage device in a first time period and is discharged in a second time period, that is, the measurement time, in order to supply the sensor element with power. A capacitor is used as the energy storage device, and the charging of the capacitor is monitored by a voltage monitoring device.

  • Patent number: 6877357
    Abstract: A method of checking the functional reliability of a pressure sensor, the air pressure being detected inside a vehicle body part, the vehicle having at least one additional pressure sensor for detecting the air pressure. With the help of the method, it may be possible to determine the integrity of the sensor without requiring any additional auxiliary equipment. To do so, the measured values of the pressure sensor and the measured values of the at least one additional pressure sensor are compared over a defined observation period. The pressure sensor is recognized as being defective if its measured values deviate by more than a predefined amount from the measured values of the at least one additional pressure sensor.

  • Publication number: 20040172205
    Abstract: The invention relates to a sensor for connection to a bus and to a method for supplying energy to a sensor that is connected to a bus, which is designed to minimize energy consumption of a sensor connected to a bus. To this end, energy for a sensor is charged in an energy accumulator during a first period and discharged during a second period, that is, during the measuring time, with the purpose of supplying energy to the sensor element. A capacitor is used as energy accumulator and charging of the capacitor is monitored by the voltage monitoring device.

  • Patent number: 5440725
    Abstract: The invention relates to a microprocessor circuit arrangement having a watchdog circuit, which monitors the proper program flow for the processor and which must be triggered in specific time intervals by the microprocessor, since otherwise it will reset (reset function) the microprocessor to the program start or the like. For reasons of simplification, it is proposed that when the microprocessor (2) recognizes that a malfunction has occurred, it spuriously triggers the watchdog circuit (5) in a selective manner to release a reset function coming from the watchdog circuit (5).

  • Patent number: 5359515
    Abstract: A vehicle occupant safety system, in particular a restraining system such as an airbag, safety-belt tightener or the like, includes a sensor device having at least two sensors, a preprocessing device comprising at least two preprocessing circuits, for the sensor signals, a computing system and a trigger circuit including at least two stages, for a safety device. For providing a high degree of safety with relatively low costs, the computing system is constructed as a single-computer system in such a way that it processes the data of two preprocessing circuits in two programs with staggered timing with respect to one another.

  • Patent number: 5176214
    Abstract: The invention relates to a safety system for motor-vehicle occupants, in particular a restraint system, such as an airbag, belt tighteners, etc., which has at least one tripping sensor that exhibits a response time, one processing unit, and one final firing stage for activating the safety system. To protect against spurious tripping, an inhibiting circuit (21) is proposed, which is triggered by the processing unit (2). It cancels an interlock of the final firing stage (5) only after an interlocking enable time (t.sub.v) has elapsed, whereby the interlocking enable time (t.sub.v) is shorter than the response time (t.sub.a) of the tripping sensor (1).
