  • Patent number: 12190653
    Abstract: Disclosed are systems and methods to detect and identify vehicular anomalies. Techniques to detect and identify the vehicular anomalies include receiving signals from various sensors, grouping the signals into detection sets, detecting anomalies by a comparison to vehicle behavior models, and cross-referencing the detection sets with each other to narrow down and identify the source of the anomaly. The detection sets may be grouped such that facets of vehicle maneuverability are captured and cover causal relations between different maneuverability mechanisms.

  • Patent number: 11757559
    Abstract: A method for detecting communication jamming attacks includes collecting, via a processor associated with a base station, local jamming information from a first vehicle and a second vehicle. The local jamming information having an attack time, an attack localization, and an attack frequency. The method further includes building a global jamming map comprising global jamming information, based on the local jamming information, determining, based on the global jamming map, a location of a communication jamming device, and causing to transmit global jamming information to a third vehicle. The global jamming information is associated with the location of the communication jamming device.

  • Patent number: 11597348
    Abstract: Techniques for using a detector coupled to a controller area network (CAN) bus of a vehicle system to identify and generate alerts in response to wake-up attacks on the vehicle system. Techniques include an electronic control unit (ECU) sending a wake-up message across the CAN bus that is detected by the detector. The detector includes memory and a processor to identify the timestamp of the wake-up message when the vehicle ignition is off. The detector determines a total operational time for the ECU over an observation time period and generates a notification of a wake-up anomaly when the total operational time over the observation time period exceeds a predetermined threshold.

  • Patent number: 11335932
    Abstract: The present disclosure provides phosphonated polymers that can be used, for example, as polymer electrolyte membranes (PEMs) and/or catalyst ionomeric binders for electrodes in PEM fuel cells, and more particularly for high-temperature PEM fuel cells. High-temperature PEM fuel cells that use phosphonated polymers of the present disclosure suffer from reduced or no acid leaching because, in at least some examples, phosphonic acid moieties are covalently bound to the backbone of the polymers. A phosphonated polymer include a backbone having one or more aromatic monomers, with each aromatic monomer having one or more phosphonic acid groups. A phosphonic acid group may include phosphonic acid or a functional group that is hydrolysable into phosphonic acid.
