Abstract: A system for data processing and storage in vehicles having a zone-based, central computing in-vehicle communications network architecture, includes a zone control unit (ZCU) that receives electronic messages from one or more sensors or electronic control units (ECUs) located within a zone of the vehicle, the ZCU comprising a protocol data unit (PDU) gating module that converts the electronic messages into a plurality of PDUs, and a switch-based Ethernet network that transmits the plurality of PDUs, using Ethernet protocol frames comprising the plurality of PDUs, to a central computing platform. The central computing platform includes an Ethernet handler module that decomposes the Ethernet protocol frames into individual PDUs for storage in a shared memory. The central computing platform further includes a plurality of parsing modules that are configured to access the individual PDUs from the shared memory and perform data processing on the individual PDUs.

Abstract: A system and method for transmitting a plurality of signals. The system includes a transmitting terminal configured to obtain and pack the plurality of signals in multiple signal sequences, with each of the plurality of signals having respective predefined periods. A receiving terminal is configured to receive and unpack the multiple signal sequences from the transmitting terminal. A controller is in communication with the transmitting terminal and the receiving terminal and configured to store a look-up table. The look-up table includes a respective pre-identifier and respective identifier for each of the plurality of signals. The controller is configured to determine if the respective predefined periods vary in magnitude within a frame. If so, the controller is configured to obtain the respective pre-identifiers and respective identifiers for each of the plurality of signals. The multiple signal sequences are based at least partially on the respective pre-identifiers and the respective identifiers.

Abstract: 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.

Abstract: Systems and method are provided for detecting an anomaly of a sensor of a vehicle. In one embodiment, a method includes: storing a plurality of sensor correlation groups based on vehicle dynamics; processing a subset of signals based on the sensor correlation groups to determine when an anomaly exists; processing the subset of signals based on the sensor correlation group to determine which sensor of the sensor correlation group is anomalous; and generating notification data based on the sensor of the correlation group that is anomalous.
