A communication control device. The communication control device has a communication control module for generating a transmit signal for controlling communication of the subscriber station with other subscriber station(s) of the bus system which uses at least one first communication phase and one second communication phase for exchanging messages between subscriber stations of the bus system, and an interface module for encoding the transmit signal in at least one part of the second communication phase of a message into an encoded transmit signal, and for inserting additional data into at least one symbol of the encoded transmit signal. The interface module is configured to insert the additional data into the encoded transmit signal as at least one symbol of the encoded transmit signal serially with the information of the symbol of the transmit signal. The symbol duration of the transmit signal and of the encoded transmit signal is identical.

An EtherCAT fieldbus system has an EtherCAT master and a number of EtherCAT slaves. The EtherCAT master and the number of EtherCAT slaves are coupled together by an EtherCAT fieldbus in order to exchange data. A method ascertains active EtherCAT slaves by way of the EtherCAT master; requests respective product codes of the active EtherCAT slaves by way of the master; ascertains a respective device identification of the active EtherCAT slaves from the respective product codes by way of the EtherCAT master, and switches the state of the EtherCAT fieldbus system into the operational state by way of the EtherCAT master if the respective device identification of the active EtherCAT slaves matches a specified device identification.

According to an embodiment, an electronic device comprises: a connecting terminal; a memory; and a processor connected to the connecting terminal and the memory, wherein the processor is configured to: identify a head unit of a vehicle connected to the connecting terminal; obtain information about a model of a vehicle or an installed operating system, associated with the identified head unit; and when the information about a specified tuning value for the identified head unit is stored in the memory, tune a register by using the specified tuning value.

A dynamically addressable master-slave system and a method for dynamically addressing slave units includes a master unit and a plurality of slave units, such that the slave units are interconnected with the master unit via a bus system. The respective network addresses of the slave units are assigned to the respective serial numbers of these slave units in a table in the master unit according to the position thereof in the system according to a determined order. Upon replacement of slave units, a list of serial numbers of the units to be replaced is transferred to the master unit in the sequence of the acquisition of the serial numbers, which master unit replaces these serial numbers in the table with the serial numbers of the replaced slave units transmitted to the master unit.

The aspects disclosed herein generally provide a method and a system of real-time data monitoring for a vehicle. The method comprises packaging monitoring data into one or more physical Automotive Audio Bus (A2B) channels according to a data package protocol; transferring the packaged monitoring data via a A2B bus; and unpackaging the transferred data and displaying the unpackaged monitoring data.

The present disclosure is directed to systems and methods directed to improving the functions of a vehicle. Systems and methods are provided that provide a custom tool that autogenerates a set of software agents that allows a system to separate processing, transmission and receiving of messages to achieve better synchronization. The disclosure herein also provides a simplified method of key provisioning by designating one client as a server and assigning a symmetric key to every other client permanently provisioned between that client and the server. Systems and method are further provided that predict faults in a vehicle. Systems and methods are also provided that preserve data in the event of a system crash. Systems and methods are also provided in which an operating system of a vehicle detects the presence of a new peripheral and pulls the related interface file for that new peripheral. Further, a data synchronization solution is provided herein which provides optimized levels of synchronization.

A transceiver device for a bus system and a method for reducing conducted emissions. The transceiver device has a transmitting stage for transmitting a transmit signal to a first bus wire of a bus of the bus system, in which bus system an exclusive, collision-free access of a user station to the bus of the bus system is at least temporarily ensured, and for transmitting the transmit signal to a second bus wire of the bus, a receiving stage for receiving the bus signal transmitted on the bus wires, and an emission reduction unit for controlling a switch-on path of a first stand-off device in the transmitting stage as a function of whether or not a dominant stage of the transmit signal occurs.

A two-wire interface (300) for connecting a first device (106) and a second device (108). The two-wire interface (300) is operable in a handshaking mode and a data transfer mode. In the handshaking mode the first wire (302) of the interface (300) is driven by the first device (106) and the second wire (304) of the interface (300) is driven by the second device (108) so that the first (106) and second (108) devices can perform a handshaking sequence. In the data transfer mode one of the first wire (302) and the second wire (304) is driven by one of the first (106) and second (108) devices to provide a clock signal, and the other wire is driven by either the first device (106) or the second device (108) depending which device is transmitting data. Accordingly, the two-wire interfaces (300) are operable in two modes (e.g. handshaking mode and data transfer mode) and one of the wires (302, 304) of the interface (300) may be driven by a different device in the two modes.
