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.

Method and device for bi-directional half duplex transmission of data

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.

Method of data transmission and a transmission and reception device therefor

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.
