An in-vehicle communication system includes a plurality of in-vehicle devices each being connected to an Ethernet network and a CAN (Controller Area Network). Each of the plurality of in-vehicle devices transmits and receives information to and from another in-vehicle device via the Ethernet network and the CAN. At least one of the plurality of in-vehicle devices is able to transmit the same information to the Ethernet network and the CAN in parallel.

The present disclosure relates to a communication device, a communication method, and a program that make it possible to perform an appropriate output control based on time synchronization for a plurality of sensors. There are provided: a communication processing control section that controls communication processing in accordance with a predetermined standard with a plurality of sensors; and a time synchronization counter to implement a timing control defined in the standard. Then, information processing is performed that is necessary for an output control that causes the time synchronization counter to time synchronize with time synchronization counters included in the respective sensors to output time data indicating a timing at which sampling data is sampled together with the sampling data sampled at a predetermined sampling cycle in the plurality of sensors. The present technology is applicable, for example, to a communication system employed in a movable body including the plurality of sensors.

A security system for a vehicle network of a vehicle is provided. The vehicle network includes a gateway and domain controllers for specific areas of the vehicle.

The security system may also utilize asymmetrical encryption keys in order to secure data within the vehicle network.

A computer can be programmed to determine that an impact to a wheel of a vehicle exceeds an impact severity threshold and transmit a message describing the impact via a vehicle communications network. An electronic controller can be programmed to make an adjustment to monitoring the component based on receiving the message in the electronic controller.

Parallel Redundancy Protocol (PRP) using non-overlapping Resource Unit (RU) groupings may be provided. A first computing device may associate to a first Access Point (AP) at a virtual Media Access Control (MAC) address. Next, the first computing device may associate to a second AP at the virtual MAC address. Then data from a data frame may be replicated to a first one or more RUs in a channel. The first one or more RUs may be assigned to the first AP. Data from the data frame may then be replicated to a second one or more RUs in the channel. The second one or more RUs may be assigned to the second AP and may not overlap the first one or more RUs.

The invention relates to a method for transmitting messages in a computer network, and to a computer network of this type. The computer network comprises computing nodes (101-105), said computing nodes (101-105) being interconnected via at least one star coupler (201) and/or at least one multi-hop network (1000), wherein each computing node (101-105) is connected via at least one communication line (110) to the at least one star coupler (201) and/or the at least one multi-hop network (1000), and wherein the computing nodes (101-105) exchange Ethernet messages with one another and with the at least one star coupler (201) and/or the at least one multi-hop network (1000). A set of two or more components are directly connected to one another in each case by two or more communication lines (110, 111), wherein each component in the set is either a computing node (101-105) or a star coupler (201), and sending components in the set of components send to at least two of the two or more communication lines (110, 111) at least a proportion of the Ethernet messages that are to be sent, and receiving components in the set of components then accept and/or forward at least a proportion of the Ethernet messages received via the two or more communication lines (110, 111) only if at least two identical messages are received via at least two different communication lines.

A pin-configurable bus termination system may includes a bus connector attached to an end of a bus. The bus connector may be configured for electrically connecting the bus to an input connector of a node. The node may include a bus termination resistance. The bus connector may include a first bus output pin, a second bus output pin and configurable first and second termination resistor pins. The configurable first and second termination resistor pins may be configurable to provide a first termination configuration and a second termination configuration. The first termination configuration may electrically interconnect the first and second bus output pins arid the configurable first and second termination resistor pins to electrically connect the bus termination resistance for terminating the bus. The second termination configuration may include an open electrical circuit between the first and second bus output pins and the configurable first and second termination resistor pins.

A communication device includes a plurality of controllers, a plurality of buses that transmit transmission information, and a gateway to which the plurality of buses are collectively connected. Each of the plurality of controllers has a pattern table that defines, for each piece of the transmission information, a transmission bus pattern, and controls the input and output of the transmission information according to the pattern table. Each of the plurality of controllers is connected to at least two buses, and outputs, to the gateway via all of the connected buses, check information for a confirmation of connections to the connected buses. The gateway determines an interrupted bus from which no check information is input, and outputs, to each of the plurality of controllers, a route switch instruction instructing use of a pattern table that does not include the interrupted bus(es).

In some embodiments, a system may include a tool drill string having a downhole device. The system may include a contact module including a first component. The first component may include a first data path capable of communicating data using a first communication protocol, a second data path capable of communicating the data using a second communication protocol, and a processor electrically connected to the first data path and the second data path. The processor may be capable of selectively routing the data between the first data path and the second data path.
