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.

Bus station connection to a bus system for restraining means and/or sensors

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.

Bus master for a bus for connection of sensors and/or ignition means

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.
