A method is provided for determining a collision characteristic of a vehicle collision for triggering safety means of the vehicle. The method has a step of an ascertainment of at least one determination-relevant time segment of a sensor signal representing the vehicle collision before a triggering time for a safety means. The method also has a step of a comparison of at least two features of the sensor signal in the at least one time segment with one another in order to determine the collision characteristic.

A method for determining a course of a lane of a vehicle. In this connection, a first marking course of a first marking of the lane and a second marking course of a second marking of the lane are initially recorded. The first marking course and the second marking course are subsequently checked for plausibility. Finally, the lane course is determined on the basis of a previous width of the lane and a plausible marking course in response to at least one marking course proving to be implausible in the checking step.

A cold gas generator for a vehicle includes a container for storing gas, and an outlet opening closed by a closure element. The apparatus for operating the cold gas generator has a first terminal for a first connecting line for providing a first operating voltage potential, and a second terminal for a second connecting line for providing a second operating voltage potential. The apparatus also has an electrical coil to actuate, in response to a coil current, a closure device for controlling a gas flow through the outlet opening, the coil being connected between the first terminal and the second terminal. The apparatus also has a firing device to open the closure element in response to a firing current, the firing device being connected between the first terminal and the second terminal.

A valve for a cold gas generator for an airbag in a vehicle includes: a valve chamber; a control chamber; a control piston; an overflow channel; a retaining element; and a shutoff element. The valve chamber includes an inlet from the cold gas generator and an outlet to the airbag. The control piston separates the control chamber and the valve chamber. The control piston is movable between an open position and a closed position, the control piston releasing the outlet in the open position and closing it in the closed position. The control piston has (i) a first active piston surface on the side of the valve chamber, and (ii) a second active piston surface on the side of the control chamber. The first piston surface is smaller than the second piston surface. The overflow channel fluidically connects the valve chamber and the control chamber to one another.

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.

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.

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.

A possibility for controlling and supplying energy to a larger number of restraint means components in a vehicle seat that can be installed in variable fashion, this possibility being able to be realized using a constructively simple and robust electrical connection, so that this connection in particular also withstands the mechanical stresses that occur during the installation and removal of the vehicle seat. For this purpose, the vehicle seat is equipped with at least one system bus for controlling and supplying energy to the individual restraint means components of the vehicle seat. In addition, means are provided for the electrical contacting of the system bus during the installation of the vehicle seat.

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.
