A vehicle and method for intra-vehicle communication within the vehicle involve a sending controller to transmit a message, and a receiving controller to receive the message. The vehicle includes one or more switches to relay the message from the sending controller to the receiving controller. The sending controller and each of the one or more switches include an egress port for transmission of the message. A processor performs bounded timing analysis to determine a total wait time during transmission of the message from the sending controller to the receiving controller as a sum of each egress port wait time at each egress port encountered by the message. Action is taken to avoid or mitigate the total wait time during transmission exceeding a deadline for the message, and the bounded timing analysis includes performing an iterative process and determining a lower bound (LB), an upper bound (UB), and a median value.

An electronic control system includes: a CAN bus included in a vehicle; an ADAS control ECU that receives a vehicle state signal indicating information about a state of the vehicle via a dedicated line which is wiring used only for communication of the vehicle state signal, and transmits a control instruction signal to the CAN bus based on the vehicle state signal; and an actuator ECU that receives, via the CAN bus, the control instruction signal transmitted from the ADAS control ECU, and performs control relating to driving of the vehicle based on the control instruction signal.

Systems, methods, and apparatus are described that enable a device to indicate availability of priority data to be communicated over a half-duplex serial bus without waiting for an ongoing transmission to be completed. In-datagram critical signaling is accommodated without breaking backward compatibility. A method implemented at a transmitting device coupled to a serial bus includes transmitting a data byte over a first line of the serial bus to a receiving device in accordance with a clock signal transmitted by a master device on a second line of the serial device, detecting a first pulse on the first line of the serial bus during a cycle of the clock signal designated for an acknowledgement or negative acknowledgement by the second device, and processing an alert indicated by the first pulse.

A relay device connected to an in-vehicle network includes a first determination unit; a second determination unit; and a relay processing unit. The first determination unit is configured to send out a high priority transfer message through a first path that runs from the first determination unit to the relay processing unit without passing through the second determination unit. The relay processing unit is configured to output the high priority transfer message, acquired through the first path, to the second determination unit and the in-vehicle device. The first determination unit is configured to send out a normal priority transfer message to the relay processing unit through a second path that runs from the first determination unit to the relay processing unit via the second determination unit. The relay processing unit is configured to output the normal priority transfer message, acquired through the second path, to the in-vehicle device.

An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

A vehicular sensor system comprising an electronic control unit and a number of sensors associated with busses of the electronic control unit. The sensors may be wired in parallel with respect to their respective associated bus. The system may comprise a multi-pin power bus providing multiplex communication between the electronic control unit and the sensors. An associated method may be utilized to initialize and operate the sensor system.

Computer network having a plurality of clocks that are synchronized with one another, that are distributed among multiple participants in the computer network, and from which a global system time of the computer network can be read out. The computer network includes a first synchronizing signal transmitter for a first synchronizing signal and a second synchronizing signal transmitter for a second synchronizing signal, and every participant can be equipped to synchronize the value of a locally stored variable quantity with a global value on the basis of the first synchronizing signal or the second synchronizing signal, and in doing so to take into account a time lag of the synchronizing signal.

Techniques are disclosed to realize a self-adaptive multiresolution digital plate (SAMDP) system that facilitates sharing of vehicle state information via a dynamically generated binary two-dimensional multispectral pattern. The binary 2D multispectral pattern adjusts its resolution to adapt to the visual perception process while communicating vehicle state information without relying on wireless communications (i.e. V2V, V2X, etc.). The techniques as described herein leverage the use of a multichannel spectral means that helps lower the error present in sensing and representation models used by automated driving systems.

A vehicle data processing method includes receiving data points from one or more sensors arranged in or around a vehicle, identifying one or more emergency events based on the received data points from the sensors, determining, with the one or more local processors of a vehicle, an instant reaction in response to the emergency events, and controlling a control mechanism of the vehicle based on the determined instant reaction.

In order to be able to better and more flexibly utilize the available isochronous bandwidth of a realtime capable Ethernet network protocol, it is provided that a number (k) of transmission cycles (Z1, . . . , Zk) are combined to create a slow transmission cycle (ZL) and two network nodes (M, S1, . . . , Sn) communicate with one another in this slow transmission cycle (ZL) in that data communication of these two network nodes (M, S1, . . . , Sn) is provided in each kth transmission cycle (Z), and/or a transmission cycle (Z) is divided into a plurality (j) of rapid transmission cycles (ZS) and two network nodes (M, S1, . . . , Sn) communicate with one another in this rapid transmission cycle (ZS) in that data communication of these two network nodes (M, S1, . . . , Sn) is provided j times in each transmission cycle (ZS).
