An inflation manifold connected to dual pneumatic tires by air hoses provides a central location for tire inflation and location of pressure sensors. A hose block connected to dual pneumatic tires by air hoses provides a central location for location of pressure sensors. The pressure sensors may be TPMS sensors or a combination of TPMS sensor and pressure gauge.

A control subsystem, method and computer program product are provided to detect the failure of a tire of an autonomous vehicle (AV) and to direct a response to the tire failure that has been detected that is appropriate under the circumstances. In this regard, the control subsystem includes processing circuitry configured to receive signals from microphone(s) carried by the AV. The processing circuitry is configured to evaluate signal characteristics of the signals to identify signals indicative of a tire failure. In an instance in which a tire failure is identified, the processing circuitry is configured to determine a type of the tire failure based upon the signal characteristics. The processing circuitry is further configured to determine remedial action to be taken based at least in part upon the type of tire failure. Different remedial actions are determined to be taken for different types of tire failures.

Monitoring a critical parameter of a trailer and issuing a severity warning including: monitoring the critical parameter to be within one of a plurality of bands and issuing a different level of the severity warning based on which band of the plurality of bands the critical parameter falls into, wherein the critical parameter includes at least one of tire pressure, tire temperature, and brake temperature; and increasing an alert level of the severity warning by one, every hour, when the monitored critical parameter indicates continuous increase or decrease over time.

A tire-inflation system for a small trailer may include a fluid pressure source mountable to the trailer, and air conduits providing sealed fluid communication between the air pressure source and the small trailer's pneumatic tires.

A method of determining a left or right side installation position of a trailer wheel of a trailer connected to a tow vehicle. A number of rotations of the trailer wheel is determined using an acceleration sensor, and a number of rotations of a left side tow vehicle wheel and a right side tow vehicle wheel is determined using an ABS sensor or ESP sensor of the left side tow vehicle wheel and the right side two vehicle wheel, respectively. A first correspondence value between the number of rotations of the trailer wheel and the number of rotations of the left side tow vehicle wheel is determined. A second correspondence value between the number of rotations of the trailer wheel and the number of rotations of the right side tow vehicle wheel is determined. A left side or right side installation position of the trailer wheel is determined based on the first correspondence value and the second correspondence value.

A tire pressure monitoring system (TPMS) sensor module as provided herein includes a pressure sensor configured to measure an internal air pressure of a tire and generate tire pressure information; a transducer configured to receive a structure borne sound signal induced by sound waves; a receiver circuit electrically connected to the transducer and configured to detect the structure borne sound signal and generate a detection indication that the structure borne sound signal has been detected; a processing circuit electrically connected to the pressure sensor and the receiver circuit, and configured to receive the tire pressure information from the pressure sensor, receive the detection indication from the receiver circuit, and generate a communication signal in response to receiving the detection indication; and a transmitter electrically connected to the processing circuit and configured to transmit the communication signal.

A method of localizing a TPMS sensor module includes transmitting, by the TPMS sensor module, a TPMS signal; and localizing, by a localization module, the TPMS sensor module based on receiving the TPMS signal at a phase array antenna including a plurality of reception antennas each configured to receive the TPMS signal. Localizing the TPMS sensor module includes measuring a phase of the TPMS signal at each of the plurality of reception antennas such that a plurality of phases corresponding to the TPMS signal are determined, and determining a location of the TPMS sensor module based on the plurality of phases.

A load based tire pressure regulation system for trucks or trailers employing an air spring maintained at a variable pressure P.sub.AS depending upon the load on the truck or trailer, includes an air pilot pressure regulator receiving air at pressure P.sub.AS and air at the pressure of at least one tire of a truck or trailer, and configured to feed air to and bleed air from the at least one tire of the truck or trailer as a function of the load on the truck or trailer. The pressure regulator is configured to feed air to and bleed air from the at least one tire of the truck or trailer based upon the pressure of the air spring P.sub.AS as a function of the load on the air spring (F.sub.AS), and further upon the recommended pressure P.sub.T of the at least one tire as a function of the load on the tire (F.sub.T).

Systems, methods, and computer readable storage media provide dynamic chassis and tire status indications associated with a vehicle. Lift axle status data may be graphically represented by a lift axle indicator dynamically provided in a shared notification/messaging space positioned within the driver's line of sight during a lift axle transition. The lift axle indicator may include a side-view representation of the vehicle including a plurality of axle sections indicating the status of each axle. The lift axle indicator may be suppressed when air pressure is stabilized. Additionally, a graphical representation of data associated with statuses (e.g., air pressure, temperature) of each tire may be provided in a top-down view representation of the vehicle including its associated tire/axle configuration and the tire pressure for each tire. The graphical representation may be configured to reflect the correct number of axles and tires per position, and may further include a tractor versus trailer designation.

A method of localizing a TPMS sensor module includes transmitting, by the TPMS sensor module, a TPMS signal; and localizing, by a localization module, the TPMS sensor module based on receiving the TPMS signal at a phase array antenna including a plurality of reception antennas each configured to receive the TPMS signal. Localizing the TPMS sensor module includes measuring a phase of the TPMS signal at each of the plurality of reception antennas such that a plurality of phases corresponding to the TPMS signal are determined, and determining a location of the TPMS sensor module based on the plurality of phases.
