Abstract:
1. A method for transmitting information in a motor vehicle among electrical components of the motor vehicle, which are connected to a data bus structure of the motor vehicle in order to transmit information and to a power line structure of the motor vehicle in order to be supplied with power, comprising: transmitting the information in successive, pre-allocated communication cycles over the data bus structure, each cycle of the successive cycles including at least one time window for transmitting a first set of the information at specific points in time and at least one event window for transmitting a second set of the information, which is different from the first set of information, in response to specific events; and contemporaneously with the transmitting of the first set of the information in the at least one time window, transmitting at least one portion of the first set of the information transmitted in the at least one time window over the power line structure, thereby causing redundant information transmission, wherein: only the information from the first set of the information which is transmitted within the at least one time window over the databus structure is also transmitted over the powerline structure, and the power line structure is not used to transmit the second set of information transmitted during the at least one event window.
