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.
摘要:
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 method and a device for activating and/or deactivating distributed control units is described, the microcomputer of a central control unit delivering corresponding activation or deactivation commands to the decentralized control units over an interface module as part of a point-to-point link.
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.
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.
