A device for a serial bus system. The device includes a receiver for receiving a signal from a bus, in which for a message that is exchanged between user stations of the bus system, the bus states of a signal received from the bus in the first communication phase differ from bus states of the signal received in the second communication phase. The receiver generates a digital signal based on the received signal, and outputs the signal to a communication control device to evaluate the data. The receiver uses a first reception threshold and a second reception threshold in the second communication phase to generate the digital signal. The second reception threshold has a negative voltage value or has a voltage value that is greater than the largest voltage value that is driven by a user station of the bus system for a bus state in the second communication phase.

An onboard device includes: a communication unit configured to communicate with an onboard device included in an onboard network; a detection unit configured to detect a new onboard device that is an onboard device newly added to the onboard network; and a sleep processing unit configured to, in a detected state where the new onboard device has been detected by the detection unit, transmit a sleep request for transitioning to a sleep state in synchronization with an onboard device included in the onboard network, to the new onboard device via the communication unit.

A bus adapter comprises: an interface unit configured to be connected to a Communication Module (CM), which is intended to communicated based on a first Communication Protocol (CP) such as CAN, via a first and a second signal lines, and to transceive bit signals through the first and the second signal lines; and a link control unit, connected to a data bus of a second CP, configured to transmit data stored in an outward buffer through the data bus, and to detect data from signals being carried on the data bus. The interface unit transmits data stored in an inward buffer to the CM via the second signal line in form of a format defined by the first CP and it drives the second signal line so that a bit string appears on the second signal line when the bit string is received through the first signal line.

The claimed interface extension device is based on a network device (DCC) having at least one previously unoccupied digital data output (OUT), to which an interface extension module (IOE) having at least one supply voltage input (S) and having a plurality of digital interfaces is coupled in the claimed manner. In this way, the supply voltage input (S) of the interface extension module (IOE) is interconnected with the digital data output (OUT) of the network device (DCC), so that in event of an error, the interface extension module (IOE) and all the digital interfaces thereof can be switched off. In addition, by measuring the sum current flowing through the outputs of the interface extension module, the load diagnosis capacity of the network configuration can be extended to the interface extension device. The claimed interconnection of the supply voltage input (S) of the interface extension module with the digital data output (OUT) of the network configuration has the advantage of also implementing a fail-safe behavior for conventional interface extension modules.

Security system for protecting a vehicle electronic system by selectively intervening in the communications path in order to prevent the arrival of malicious messages at ECUs, in particular at the safety critical ECUs. The security system includes a filter which prevents illegal messages sent by any system or device communicating over a vehicle communications bus from reaching their destination. The filter may, at its discretion according to preconfigured rules, send messages as is, block messages, change the content of the messages, request authentication or limit the rate such messages can be delivered, by buffering the messages and sending them only in preconfigured intervals.

A vehicle control apparatus is applicable to an intelligent vehicle, a new energy vehicle, or the like and includes a first circuit board, on which an internal network interface is disposed, where the vehicle control apparatus communicates with an in-vehicle network of a vehicle by using the internal network interface, and a second circuit board, on which an external network interface is disposed, where the vehicle control apparatus communicates with a vehicle external network by using the external network interface.

According to one embodiment, an adapter apparatus includes a first connector conforming to the first standard, a second connector conforming to the second standard, a first transmitter and circuitry. The first transmitter transmits a first signal to a first external apparatus connected via the first connector. The first signal associates with a request to determine whether a first mode is supported by the first external apparatus. The first mode corresponds to a communication mode that conforms to a second standard via the first connector. The circuitry generates a second signal when the first external apparatus does not support the first mode. The second signal is used to make an indication representing that the first external apparatus does not support the first mode.

A method for serial data transfer in a bus system having at least two bus subscribers that exchange messages via the bus, the transmitted messages having a logical structure according to CAN standard ISO 11898-1, the logical structure encompassing a start of frame bit, arbitration field, control field, data field, CRC field, acknowledge field, and end of frame sequence, the control field encompassing a data length code that contains an information item regarding the length of the data field. The method is characterized in that when a first marker (EDL) is present, the control field of the messages, divergently from ISO 11898-1, encompasses more than six bits; the first marker (EDL) being implemented by way of a recessive bit in the control field, and when the first marker is present, the recessive bit of the first marker (EDL) being followed, in all data messages, by at least one dominant bit.

An apparatus for auto addressing includes a communication bus interface configured to receive an address assignment request to assign an address to the apparatus. A functional connection is configured to activate a device connected to the apparatus. A detector is configured to measure a characteristic of the device and to compare the characteristic with a validation parameter. The characteristic depends on the functional connection. An address assignment circuit is configured to store the address in a memory of the apparatus in response to receiving the address assignment request at the apparatus, and the characteristic being validated with the validation parameter.

A system, method, apparatus and electronic control unit are provided for centralized data collection at a single controller device (110) in a distributed service-oriented system (100) by applying one or more classifiers (102-104, 114) to a message traffic packet (1) received at the Ethernet switch (101) of the single controller device to selectively identify service update information from service-oriented traffic messages in the message traffic packet without generating additional message traffic packets on the network system bus, and by mirroring each message traffic packet (3) containing service update information to a processing element (111) in the single controller to identify and extract specified data from the identified service update information for storage in a centralized database which is updated as services publish new information on the network system bus.
