摘要:
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.

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.
摘要:
A method for monitoring at least one glow plug of an internal combustion engine in which a time-dependent variable, which characterizes the current flowing through the at least one glow plug, is compared for fault recognition to at least one time-dependent minimum and/or maximum threshold value, and a fault is recognized if the time-dependent variable is greater and/or less than the minimum and/or maximum threshold value. The method is characterized in that the first derivative of the time-dependent variable is compared to the first derivative of the maximum threshold value and the second derivative of the time-dependent variable is compared to the second derivative of the maximum threshold value, and a fault is recognized if the first derivative of the time-dependent variable is less than the first derivative the maximum threshold value, and the second derivative of the time-dependent variable is less than the second derivative of the maximum threshold value.
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.

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°. 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.

摘要:
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.
摘要:
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.
