A method and apparatus for use in a mobile device telemetry system is disclosed. The method and apparatus relate to aspects in a mobile device protocol health monitoring system. The method and apparatus provide a system to monitor and assess protocol health, log protocol health data and communicate the logs of protocol health data to a remote system. The system may also take corrective actions based upon specific indications of protocol health. The method and apparatus also provides protocol health indications and corrective actions based upon monitoring the message transmission rate. The method and apparatus also provides protocol health indications and corrective actions based upon monitoring for a line disconnect.

In a fraud-detection method for use in an in-vehicle network system including a plurality of electronic control units (ECUs) that exchange messages on a plurality of networks, a plurality of fraud-detection ECUs each connected to a different one of the networks, and a gateway device, a fraud-detection ECU determines whether a message transmitted on a network connected to the fraud-detection ECU is malicious by using rule information stored in a memory. The gateway device receives updated rule information transmitted to a first network among the networks, selects a second network different from the first network, and transfers the updated rule information only to the second network. A fraud-detection ECU connected to the second network acquires the updated rule information and updates the rule information stored therein by using the updated rule information.

A system for simultaneously testing whether a plurality of electronic devices connected via a communication network correctly handle exceptions. The system includes a communication network, and a plurality of electronic devices and a testing device connected via the communication network. The testing device includes an electronic processor. The electronic processor is configured to send a first status query message to the plurality of electronic devices, send fuzzed data to one or more of the plurality of electronic devices, and send a second status query message to the plurality of the electronic devices. The electronic processor is also configured to, for each electronic device that responds to the first status query message with a valid response and responds to the second status query message with an invalid response or fails to respond to the second status query message, record the electronic device in a failure log.

A vehicle includes a data communication network, a serial data bus, and a plurality of electronic nodes in signal communication with the serial data bus. The vehicle further includes a node identification system configured to store a several different diagnostic tests, along with expected operating data corresponding to a given diagnostic test. The node identification system sorts the plurality of nodes into individual node groups in response to performing one or more diagnostic tests among the different available diagnostic tests.

Techniques and screening messages based on tags in an automotive environment, such as, messages communicated via a communication bus, like the CAN bus. Messages can be tagged with either a binary or probabilistic tag indicating whether the message is fraudulent. ECUs coupled to the CAN bus can receive the messages and the message tags and can determine whether to fully consume the message based on the tag.

A system and method of controlling individual trailer brakes on a towed trailer supporting numerous fault tolerant behaviors including activating each operational brake when a brake is shorted. System operates in multiple modes where it operates with traditional brake controllers, operates in a degraded braking mode without a brake controller and in the preferred mode it retrieves vehicle information from tow vehicle and then communicates with a brake actuator controller over the trailer brake wire. When braking system includes wheel sensors traditional antilock releases are provided and unlike other braking systems this brake actuator controller can maintain wheel speeds below the trailer speed reducing or eliminating periodic wheel releases. System also diagnoses the mechanical operation of the trailer brakes including; identifying when brake adjustment is required, when brake friction surfaces are degrading, as well as diagnosing sensors, braking signals and brake actuator interfaces.

A detection system includes: a signal output unit configured to output, to a measurement target, a measurement signal that exhibits a predetermined temporal change; a signal measurement unit configured to measure a response signal, to the measurement signal, from the measurement target; a calculation unit configured to calculate an impulse response of the measurement target, based on a measurement result of the response signal measured by the signal measurement unit; and a detection unit configured to detect abnormality regarding the measurement target, based on the impulse response calculated by the calculation unit.

A detection device includes: a switch provided to a transmission path that connects a plurality of function units to each other; a measurement unit configured to measure a signal that passes the transmission path, at a first node on a first end side of the switch and at a second node on a second end side of the switch; and a detection unit configured to compare a measurement result at the first node and a measurement result at the second node, which are obtained by the measurement unit, with a reference measurement result which is a measurement result for reference, and detect abnormality regarding the transmission path, based on a result of the comparison.

An electronic device is disclosed, which is connectable with a CAN bus or other broadcast network. The electronic device programmed to compute expected periods and period variability metrics for historical accumulations of messages for different message headers and to identify periodic message headers based on the period variability metrics, and is further programmed to detect a temporal anomaly as a deviation of a period of a most recent set of two or more messages with a periodic message header from the expected period for the periodic message header, and to generate an alert indicating the detected temporal anomaly. The electronic device may be further programmed to maintain a state machine for a vehicle (or other platform) including the CAN bus and perform state-aware anomaly detection.

Operation and motion control, by a vehicle's ADAS or AD features, is improved in ways suitable to EVs having higher driving and handling performance. The vehicle dynamic model for high rates of lateral acceleration (e.g., sharp cornering or taking curves having a small radius of curvature as faster speeds) is improved by one or more of optimizing time cornering stiffness with a sigmoid function and/or altering front/rear steering angle to account for roll steer and compliance steer, based on vehicle testing. Indicators for lane departure warning or collision warning, evasive steering, or emergency braking are therefore reliably extended to allow higher performance maneuvers.
