摘要： A central control unit (ZS) and several data processing units (DV1, DV2) for controlling restraint devices (RH1, ..., RHk) are coupled to a bus line (BL). The central control unit (ZS) sends interrogation or control signals in the form of data telegrams to an individual or to all data processing units (DV1, DV2). The data processing units (DV1, DV2) send back response signals to the central control unit (ZS) to answer given interrogation or control signals. In order to enable sure allocation of interrogation and control signals to the data processing units (DV1, DV2) and reliable detection of monitoring data of the data processing units (DV1, DV2) and their restraint devices (RH1, ..., RHk), the interrogation or control signals are data telegrams, all having the same frame structure (I, II, III) consisting of a first area (I) with n control bits, a second area (II) with m information bits and a third area (III) with p check bits.

摘要： The invention relates to a method for signal transmission in a bus system, superposed on a direct supply voltage. Previously in a bus system, voltage signals were sent to modules from the central unit and said modules could respond by altering the current input. This has the disadvantage that the current input, which already has to be kept relatively low due to the energy consumption, is relatively susceptible to faults and that the process of faultlessly detecting the signals sent by the modules in the central unit is complex, accordingly. According to the invention, the modules of the central unit also respond with voltage signals superposed on the direct supply voltage. The central unit delivers the direct supply voltage via a resistor of the bus line for the duration of the signal transmission through the modules so that the voltage signal of the modules can be detected in the central unit on the bus line, on the side of the resistor facing away from the direct supply voltage. The invention is particularly suitable for use for bus systems in motor vehicles, especially for a sensor data bus.

摘要： The invention relates to a method for transmitting power and data in a bus system (5) provided for occupant protection devices (1.1), whereby, by means of the bus system (5), digital data is exchanged between a central processing unit (7) and a plurality of control modules (6) of occupant protection devices (1.1) which can be triggered. Said occupant protection devices are especially used in motor vehicles. The control modules are connected to said central processing unit in a communicative manner. According to the inventive method, power is supplied to the control modules (6) via the bus system (5). The energy stores (1.4) provided in peripheral control modules (6) of occupant protection devices (1.1) are discharged when the occupant protection device is triggered. Said energy stores must be recharged again after the triggering action. However, the bus system which is also required for transmitting data is subjected to a heavy load if the recharging process occurs immediately after triggering. The dynamic bus system load can be avoided such that the transmission of data to other control modules can be additionally guaranteed. This is achieved by suppressing the recharging of the energy stores (1.4) of the triggered occupant protection devices (1.1), preferably until a reset instruction is given. The invention also relates to the application of the method especially in a bus system provided for occupant protection devices (1.1) used in motor vehicles.

摘要： Several clearly separated data channels can be used for transmission in a restraint system, wherein a central control unit (ZS) and several data processing units (DV1, DV2) are connected to a bus line (BL), said data control units being provided to control the restraint devices (RH1, à, RHk). High-priority, urgent data is transmitted with a high signal level and at high bit rates. Low-priority, less urgent data is transmitted with a low signal level and at low bit rates. High-priority, less urgent data is transmitted with a high signal level and at lower bit rates while low-priority, urgent data is transmitted with a low signal level and at high bit rates.

摘要： According to the inventive signaling output stage, the modules are arranged between two lines, and an upper switching means is provided between a first voltage potential and the first line. A middle switching means is provided between the first and second line, and a lower switching means is provided between a second voltage potential which is lower than the first voltage potential. By using said signaling output stage, it is possible to control the modules together over both lines and over each one of the lines when a permanent disturbance potential is applied on the other line. The signal transmission results then as a potential difference between the permanent disturbance potential of the short-circuited line and the undisturbed line whose potential is correspondingly controlled. The invention also relates to the use of said signaling step especially for signaling in bus systems for occupant protection systems in motor vehicles.

摘要： A central control unit (ZS) and several data processing units (DV, DV1, DV2) are connected to a bus line (BL) in a restraint system, each of said units being provided to control one or more restraint devices (RH1, à, RHk). In order to ensure that the restraint system remains as operational as possible in case of a short circuit, each data processing unit (DV, DV1, DV2) carries out a short circuit measurement on the bus line (BL) and initiates time measurement with the emergence of a measured short circuit. Each data processing unit (DV, DV1, DV2) has a circuit-breaker to close or interrupt the bus line (BL). The circuit-breaker is opened when the measured short circuit lasts longer than a given waiting time.

摘要： The restraint system comprises a central control unit (ZS) that is connected to several data processing units (DV1, DV2) by means of a bus line (BL), each of said units being provided to control one or more restraint devices (RH1, ..., RHk). In order to ensure that the restraint system remains operational in case of faulty power supply (SV) in the central control unit, said central control unit (ZS) is switched over to the battery voltage (UBA) of the vehicle as new power supply voltage. The central control unit (ZS) then signalizes the switchover to all data processing units (DV1, DV2), whereupon all data processing units (DV1, DV2) adapt their circuits to the new power supply voltage level (UBA).

摘要： The invention relates to an occupant protection system having a central unit, sensors and a plurality of control modules which are connected by means of a bus system so that they can communicate and which are provided for triggering occupant protection devices. In a large number of occupant protection systems, sensors and control modules provided for triggering occupant protection devices considerably increase the amount of wiring required when they are connected to a central unit in a communicative manner. For this reason, bus systems already exist for control modules provided for triggering occupant protection devices. The aim of the invention is to further reduce the amount of wiring required in a simple manner. To this end, the sensors are at least partially integrated in the bus system by means of additional control modules which are assigned to said sensors. In addition, an actual sensor value is sent as a diagnostic response from the control modules of the sensors to the bus system within the scope of a process of the diagnostic inquiry-diagnostic response which triggers a functional test of the control modules provided for triggering occupant protection devices. Said value is processed by the central unit and/or by the other control modules. The invention also relates to the use of these occupant protection systems in motor vehicles.
