Dynamic controller area network (CAN) messaging is provided. A central gateway of a vehicle includes a processor and a storage, connected to a plurality of vehicle buses, each of the vehicle buses connected to one or more electronic control units (ECUs), The central gateway receives a message from a client of the ECUs, the message requesting a dynamic CAN signal. The message is forwarded over the plurality of vehicle buses to a server of the ECUs. A response from the server is received to the central gateway, the response specifying availability of the dynamic CAN signal. The response is forwarded to the client.

The wiring diagnostic data includes information with respect to electrical operation of a plurality of segments of wiring of the vehicle. A machine-learning model of the cloud system is utilized to analyze the wiring diagnostic data. Responsive to the machine-learning model identifying an issue with the electrical operation based on the wiring diagnostic data, a response is sent from the cloud system to the vehicle, the response including one or more corrective actions to be performed by the vehicle to address the issue.

Automotive network vehicle bus diagnostics

An electronic control unit comprises circuitry to receive a combined signal via a vehicle bus of a vehicle, wherein the combined signal contains a combination of a data signal and a watermark signal, which can be a radio frequency (RF) signal or an analog baseband signal, wherein the data signal includes a message, circuitry to extract a watermark from the watermark signal, circuitry to verify the watermark based on a comparison of the watermark with a pre-defined watermark, circuitry to extract the data signal from the combined signal and obtain the message from the data signal, and circuitry to authenticate the message based on the verification of the watermark.

Vehicle bus message authentication using watermarking

A system includes a processor configured to wirelessly broadcast a message obtained from a first originating vehicle BUS or controller, following a determination that the message was on a pre-approved list for broadcast and having encrypted the message utilizing a temporary random key generated for a message session. The system may include vehicle controllers, a gateway module, and vehicle BUSSES connecting the system controllers to the gateway module. The gateway module may include a memory storing a list of pre-approved message types and corresponding source types, and a processor configured to receive a message from one of the vehicle controllers over one of the vehicle BUSSES to determine if a message type and source type of the received message matches an element of the list.

Method and apparatus for secure wireless vehicle bus communication

A first device, for communications on a communications bus is programmed to: identify a configuration on a communications bus comprising one of (1) a second LIN device and no second custom device, (2) the second custom device and no LIN device, and (3) both the second LIN device and the second custom device and select an operating mode specified for communications with the identified bus configuration. A third device for communications on the communications bus is programmed to identify that a fourth device on the communications bus is one of (1) a calibration device programmed to control two-way communications with the third device, (2) a LIN master device programmed to control two-way communications with the third device and (3) a custom master device programmed to only receive messages from the third device; and select an operating mode specified for communication with the other device.

Smart network devices

A vehicle includes a rail-mounted component. The rail-mounted component can be equipped with one or more restraints. A restraint monitoring system monitors the one or more restraints. The restraint monitoring system includes a restraint control module and a rail-mounted component control module. The rail-mounted component control module can include a restraint deployment loop and a restraint diagnostic loop for relaying restraint deployment signals and restraint diagnostic signals, respectively, between the restraint control module and the rail-mounted component control module.

Restraint monitoring system for a vehicle

A first electronic control unit (ECU) is in communication with a second ECU over a vehicle bus. The first ECU is configured to generate functional safety values and security protection values for a message, validate the security protection values for the message, and send the message to the second ECU including the security protection values but not the functional safety values.

End-to-end controller protection and message authentication

Method and apparatus are disclosed for controller area network message authentication. An example disclosed vehicle includes a data bus and a first control unit communicatively coupled to the data bus. The example first control unit generates a secured message by (a) calculating a message authentication code, (b) truncating the message authentication code, (c) truncating a freshness value used to generate the message authentication code, and (d) placing portions of the truncated message authentication code and the truncated freshness value in separate portions of the secured message.

Controller area network message authentication

Systems and methods are disclosed for private vehicle-to-vehicle communication. An example disclosed vehicle communication system includes sensors to monitor a target vehicle, and a controller. The example controller generates a pseudo-anonymous identifier based on an identifier and an attribute of the target vehicle. Additionally, the controller broadcasts a first message including the pseudo-anonymous identifier, a random number, and a public key. In response to receiving a second message including the identifier and the random number, the example controller broadcasts a third message encrypted with a symmetric key included in the second message.

Private vehicle-to-vehicle communication

An automotive diagnostic tool includes an antenna, a speaker, and a controller. In response to a vehicle diagnostic request, the controller generates a carrier frequency that corresponds to a predetermined frequency associated with electromagnetic emissions from an imbalanced differential channel in the vehicle. The controller alternately enables and disables the differential channel resulting in an audio signature and a baseline audio signature. The controller demodulates signals from the antenna based on the carrier frequency and outputs the demodulated signal to the speaker for analysis by a listener. The demodulated signal may be further processed by the controller to identify emissions from the communication network.
