A method and a device for controlling a glow plug in a combustion engine, where a state of aging A of the glow plug is ascertained, and the control of the glow plug is influenced as a function of the state of aging A of the plug.

Method and device for controlling a glow plug

In a method for detecting a replacement of sheathed-element glow plugs in an internal combustion engine, an electrical parameter of the sheathed-element glow plug is determined during a driving cycle and is compared with a stored value of the same electrical parameter of the sheathed-element glow plug that was determined in a preceding driving cycle. In the driving cycle, the same electrical parameter is determined for all sheathed-element glow plugs installed in the internal combustion engine, and the determined pattern of the electrical parameter is compared with a pattern that was ascertained in a preceding driving cycle, a replacement of a sheathed-element glow plug being detected if the pattern of the driving cycle deviates from a pattern of the preceding driving cycle.

A device and a method for controlling at least one glow plug of a motor vehicle are described. The at least one glow plug is controlled as a function of the operating state of the internal combustion engine. In this case, the control is effected as a function of a variable which depends on the exhaust gas temperature and/or as a function of the fulfillment of a fuel quantity condition and/or time condition.

Method and device for controlling at least one glow plug of a motor vehicle

A night vision device for a vehicle is provided, in which a travel path that is set or is to be set is inserted in an image recorded by a camera, the travel path being determined from an evaluation of a location-finding or travel direction sensor.

Night vision device

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.

In a method and a device for driver assistance, traffic elements that point to potential danger zones are detected on the road, using a camera. If such potential danger zones are detected, at least one headlight of the vehicle is controlled in such a way that the potential danger zone is illuminated.

Method and device for driver assistance

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.

Method for controlling at least one sheathed-element glow plug in an internal combustion engine and engine controller

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.

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 control/evaluation system for a set of sensors, in particular in motor vehicles, has a plurality of areas, each of which has at least one controller and a plurality of sensor devices connected thereto; the controllers may be connected to each other for a common application function.

Control and evaluation system for a compound sensor

A data transmission method and a transmission/reception device are described, the data transmission taking place via intermediate memories without the transmitter receiving direct feedback from the receiver regarding the success of the data transmission. Furthermore, at least one transmission and/or reception device is described which forms an interface between at least two control units and has intermediate memories.

A collision prevention method for motor vehicles is provided, in which method obstacles in front of the vehicle are detected by an on-board positioning system, a collision probability is calculated from the position data, and one or more responses to prevent a collision are triggered as a function of the collision probability. At least one of the responses is a preparatory measure accelerating the implementation of a command, which may be output later, to decelerate the vehicle, without the preparatory measure itself having any significant decelerating effect on the vehicle.

A radar sensor platform for clearance measurement in a vehicle has at least four radar sensors, an input being entered if necessary using an input device indicating that a width measurement of a parking space is desired and the four radar sensors then enlarging their horizontal beam angle and the arrangement for acoustic and/or visual output emitting a signal as a function of the measurement of the parking space width. This signal is, for example, the parking space width or a warning. The horizontal beam angle for the parking space measurement is at least 170&#xb0;. The side clearances of the vehicle in the parking space may also be displayed. Furthermore, centered parking is possible using the acoustic and visual aids. The radar sensor platform may be installed either in the front and/or rear of the vehicle.

A method and an apparatus for operating a radar sensor system with a number of adjacent individual sensors (), extensively synchronized with one another, for determining the position of a target object () are proposed. In one measurement cycle, the transit time of the radar signal emitted from one individual sensor and reflected by the target object to this individual sensor () (direct echo ()) and to a different individual sensor () (cross echo ()) is evaluated. From the evaluation of the direct and cross echoes (), at least the position of the target object () is determined, and a detection quality signal (Q) is ascertained, and once a predetermined amount of the detection quality signal (Q) is reached for a target object (), a calibration is performed.

An intrusion sensor which includes a first light guide arrangement and a second light guide arrangement for detecting the severity of an accident in a vehicle. An interval having a width is positioned between the two light guide arrangements. In this case, the first light guide arrangement is positioned in the direction of an intrusion side. The second light guide arrangement is positioned in the direction of the vehicle interior side.
