A method for controlling a suspension component of a vehicle, in which a control unit of the suspension component continuously generates a plurality of control requirements according to a generation clock frequency, each requirement comprising a control value, for an actuator of the suspension component. A bus system of the vehicle continuously transmits to the actuator the control requirements generated by the control unit according to a transmission clock frequency. The actuator calculates a target output value for the suspension component from the control value of each transmitted control requirement and an actual output value of the suspension component, and adjusts the suspension component corresponding to the calculated target output value.

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.

In some implementations, a scheme for data communication in an automobile includes generating a cleartext message to be transmitted to a second ECU, generating a pseudo-random counter by applying a pseudorandom function to a counter value that is incremented for each cleartext message generated by the ECU; combining the cleartext message and the pseudo-random counter to create a randomized message; selecting from a plurality of available cryptography techniques, a selected cryptography technique; applying to the randomized message, the selected cryptography technique to create a ciphertext; and transmitting to the second ECU over the CAN bus, the ciphertext.

A method at a computing device for providing vehicle data to a client, the method including receiving a data object at an ingestor block at the computing device, the ingestor block comprising a plurality of ingestor instances capable of interacting with different entities; converting the data object to a frame; providing the frame to a translation stack at the computing device to convert the frame into a normalized message; and providing the normalized message to the client.

Embodiments include a sensor node, a method of forming the sensor node, and a vehicle with a communication system that includes sensor nodes. A sensor node includes an interconnect with an input connector, an output connector, and an opening on one or more sidewalls. The sensor node also includes a package with one or more sidewalls, a top surface, and a bottom surface, where at least one of the sidewalls of the package is disposed on the opening of interconnect. The sensor node may have a control circuit on the package, a first millimeter-wave launcher on the package, and a sensor coupled to the control circuit, where the sensor is coupled to the control circuit with an electrical cable. The sensor node may include that at least one of the sidewalls of the package is crimped by the opening and adjacent and co-planar to an inner wall of the interconnect.

An in-vehicle network system includes: an upper device; a first intermediate device that is connected to the upper device directly or via at least one device and is configured to communicate with the upper device using a first communication system; a second intermediate device that is connected to the upper device directly or via at least one device and is configured to communicate with the upper device using a second communication system; and a first lower device that is directly connected to the first intermediate device and is configured to communicate with the first intermediate device using the first communication system, and that is directly connected to the second intermediate device and is configured to communicate with the second intermediate device using the second communication system.

A subscriber station for a serial bus system are provided. The subscriber station includes a message creating device for creating a message to be transmitted serially via a bus of the bus system for at least one further subscriber station of the bus system, so that the message has a first time segment and a second time segment, and a transceiver device for serially sending the message to the bus in such a way that data in the first time segment are sent with a slower data rate than in the second time segment, the transceiver device having in the second time segment at least at times an exclusive, collision-free access to the bus, the message creating device to insert an identification number into the first time segment and to begin the second time segment at the latest after the final bit of the identification number and an additional bit.

Vehicle diagnostic access authentication techniques comprise, in response to receiving a request for diagnostic access to the vehicle that comprises a public key certificate, transmitting an authentication challenge back to an external testing tool that causes it to obtain, from a PKI computing system, and return to the vehicle a signed authentication challenge comprising a digital signature. The vehicle then determines whether the digital signature is valid using the public key certificate and, when valid, a set of diagnostics associated with a diagnostic role specified by the diagnostic access request are unlocked. When any of the set of unlocked diagnostics associated with the diagnostic role match any of the set of diagnostics for the set of components specified by the diagnostic access request, the external testing tool is granted diagnostic access to the vehicle to execute the one or more matched diagnostics.

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.

A vehicle control system includes a first controller mounted in a vehicle and a plurality of second controllers mounted in the vehicle, each of the plurality of second controllers being configured to control at least one in-vehicle device allocated to the second controller among a plurality of in-vehicle devices mounted in the vehicle, wherein the first controller is configured to perform communication with each of the plurality of second controllers via a first type network, the communication regarding an operation of the second controller, and at least the plurality of second controllers are configured to be able to communicate with each other via a second type network different from the first type network.
