A passenger protection device in a motor vehicle includes at least one airbag, at least one gas generator for filling the airbag, an airbag control device for activating the airbag, means for acquiring the deployment speed of the airbag, and means for regulating the filling quantity of the airbag, taking into account its deployment speed. In order for the passenger protection device to implement a controlled filling of the airbag dependent on its deployment speed, at least one flow-off valve is provided that is situated between the gas generator and the airbag. In addition, controllable actuating means are provided for the sealing of the flow-off valve.
摘要:
A method for detecting an optical structure from image sequences of an image recording system. An optical flow field is derived from the image sequences of the image recording system. The vectors of the optical flow field are broken down into components by projection onto a coordinate system of the image recorded by the image recording system. At least one component of the flow vectors is analyzed for a change of direction. The image elements containing a change of direction of a vector component are connected to form a curve.
摘要:
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.
摘要:
A method and a device for bi-directional transmission of data are provided such that an interface for digital communication on a signal line is obtained which is suited for automotive use. In accordance with the present invention, the following are provided: at least one switchable load unit, the load unit of the temporary transmitter being able to be deenergized prior to transmission of the data; and being able to be reenergized after transmission of the data; in each case at least one switchable current-source unit is assigned to the load unit, the current-source unit of the transmitter being able to be clocked to generate the signals to be transmitted via the communication path; and in each case at least one comparator unit is assigned to the load unit, corresponding output signals being generated at the comparator unit of the receiver from the signals transmitted via the communication path.

A method for controlling at least one sheathed-element glow plug in an internal combustion engine, the temperature of the sheathed-element glow plug being controlled as a function of at least one operating parameter of the internal combustion engine in such a way that optimal combustion properties of the internal combustion engine prevail at all times.
摘要:
A method and a device for detecting the exchange of sheathed-element glow plugs (GPE) in a combustion engine, in which at least one electric characteristic quantity of at least one glow plug is measured at the beginning of a driving cycle, an instantaneous value of this characteristic quantity is determined and compared to at least one stored value of the same electric variable quantity of this glow plug, which was determined at the beginning of at least one preceding driving cycle, and if the deviation of the instantaneous value from the stored value exceeds a specifiable threshold value, an exchange of the glow plug (GPE) will be inferred.
摘要:
A sheathed-element glow plug unit includes an input for connecting the sheathed-element glow plug unit to a control line, via which a sheathed-element glow plug of the sheathed-element glow plug unit is able to be controlled. The sheathed-element glow plug unit has an output, via which at least one further sheathed-element glow plug unit is able to be connected to the control line.
