摘要： In occupant protection systems having a large number of sensors and control modules for triggering occupant protection devices, the amount of wiring is significantly increased if they are to be communicatively connected to a central unit. For this reason, bus systems have already been suggested for the control modules for triggering occupant protection devices. In order to further reduce in the wiring, sensors are at least partially integrated into a bus system with additional control modules that are allocated to these sensors. Within the context of a diagnosis process of interrogation and response, which triggers a function test of the control modules for triggering the occupant protection devices, an actual sensor value is sent to the bus system from the control modules of the sensors as a diagnosis response. This response is processed by the central unit and/or the other control modules.

摘要： Before digital data impulses are transmitted from a transmitter to a receiver that includes a data acquisition signal generator, at least one synchronizing impulse (syn1, . . . ) is transmitted for synchronizing the transmitter with the receiver with regard to a sync frequency that is repeatedly updated to provide a current accepted sync frequency. The at least one synchronizing impulse and the data impulses are Manchester encoded which combines timing (synchronizing) and data signals. An impulse flank change occurring centrally in an impulse width is used as a synchronization point of time. Stepping pulses occurring between two consecutive synchronization points of time are counted and the resulting count is used to determine the sync frequency in response to the occurrence of a synchronizing impulse and at a synchronization point of time. A time shift or delay occurs between data impulses and synchronization points of time. This delay is taken into account by a corresponding time shift in the scanning of the logic levels “0” and “1” of the data impulses. This type of signal transmission is especially suitable for a signal bus in a passenger protection system.

摘要： An unintended triggering of a safety device, such as an airbag in an occupant protection system, especially in motor vehicles is prevented by storing already during manufacturing of the module or modules, a blocking information in a memory location of the module or modules. The blocking information is preferably temporarily stored in place of a rated information, which is then overwritten when the module has been installed in the protection system for activating the system. In addition, the module is protected against electromagnetic and/or electrostatic disturbances at the input to the bus system.

摘要： An arrangement for generating digital signals on first and second bus lines is tolerant of most line faults, and includes modules connected to both lines, an upper switch between a first potential and the first line, a middle switch between the two lines, and a lower switch between the second line and a second potential lower than the first potential. The switches are controlled to generate digital signals as the potential difference between the two lines. If a fault potential (e.g. a short to ground or other potential) arises on one line, then the switches drive the non-faulty line to provide the required signals relative to the fault potential on the faulty line. Closing the middle switch ensures that the two lines are at the same potential for a low signal. This arrangement is for is signaling in various bus systems, e.g. in vehicle occupant protection systems in motor vehicles.

摘要： Previously in a bus system, voltage signals were transmitted from the central unit to the modules, which could reply thereto by variation of the current input. A disadvantage thereby is the relatively high susceptibility to interference of the current input, which itself already must be kept relatively small due to the energy consumption, as well as the correspondingly high effort and expense for an error-free recognition of the signals transmitted from the modules in the central unit. It is now suggested, that the modules also answer to the central unit by means of voltage signals superposed on the direct supply voltage, whereby for the time duration of the signal transmission by the modules, the central unit provides the direct supply voltage to the bus line over a resistor, so that the voltage signal of the module can be detected in the central unit on the bus line on the side of the resistor facing away from the direct supply voltage. A preferred application for bus systems in motor vehicles, especially for a sensor data bus, is provided.
摘要翻译：在总线系统中，通过选择性地将第一和第二电压电平施加到总线，电压信号从中央单元传输到连接到总线的模块。通过选择性地将总线线路拉至第三电压电平，模块也通过叠加在总线上的直接电源电压上的电压信号来应答。对于其中一个模块进行信号传输的持续时间，中央单元通过电阻向总线提供直接电源电压，从而可以在中央单元上检测总线上模块的电压信号电阻器的侧面远离直接电源电压源。优选的应用是用于机动车辆中的总线系统，特别是用于传感器数据总线。

摘要： A central control unit and a plurality of data processing units are connected to a bus line and are provided to control restraint devices. The central control unit sends query signals or control signals in the form of data telegrams to all or certain individual data processing units and the data processing units send response signals back to the central control unit in response to certain query signals or control signals. To permit a reliable allocation of query signals and control signals to data processing units and reliable acquisition of monitoring data of data processing units and their restraint devices, the query signals or control signals and the response signals are data telegrams, all of which have the same frame structure, having a first region with n control bits, a second region with m information bits and a third region with p check bits.

摘要： The restraint system is composed of a central control unit, which is connected via a bus line to a plurality of data processing units each of which is intended to drive one or more restraint devices. To keep the restraint system operational if the power supply in the central control unit becomes defective, a changeover to the vehicle battery voltage as the new supply voltage is effected in the central control unit. The central control unit then signals the changeover to the new supply voltage to all the data processing units. All the data processing units thereupon adjust their circuits to the new supply-voltage level.

摘要： In the restraint system, a central control unit and a plurality of data processing units are coupled to a bus line, each of the data processing units being provided to activate one or more restraint devices. In order to keep the restraint system operational to the extent possible in the event of a short circuit, each data processing unit measures for short circuits on the bus line and starts timing if a short circuit is detected. Each data processing unit has a circuit breaker, with which the bus line can be closed or interrupted. This circuit breaker is opened if the short circuit measured is longer than a preset waiting time.
