  • Patent number: 8981919
    Abstract: A flow indication system for a central tire inflation system is provided. The flow indication system provides a venturi in fluid communication with the conduit providing air to a tire. A pressure reading is taken at the inlet and throat of the venturi and the air flowing through the venturi is calculated based on the pressure differential. According to some embodiments, the pressure readings are provided to a microcontroller that uses a table and interpolation algorithms to calculate the flow of the air flowing through the venturi, such as the mass of air in a given unit of time (grams/second for example). In one embodiment, two separate pressure sensors are coupled to different ends of a narrowed orifice that causes a pressure change in the flow as flow rate increases in the throat of the sensor. This pressure change is then used to calculate a proportional flow that can then be broadcast to various parties instead of an on/off reading.

  • Patent number: 8798853
    Abstract: A tire condition monitoring system stores information representing a number of dual wheels having two tires arranged closely adjacent to each other on, for example, a commercial vehicle. The system measures internal air temperatures of the tires on all of the wheels, and stores temperatures measured when a system reset is executed as reference temperatures. The system determines calculated values based on the temperatures measured for each tire until a measured temperature exceeds the corresponding reference temperature by 20 degrees Celsius or more. The system arranges the calculated values in an order and determines that a number of the calculated values high in the order are calculated values of temperatures of tires mounted on the inside wheel. The number of calculated values corresponding to a dual wheel is equivalent to the number of dual wheels. Thus, the system determines which tires are mounted on an inside wheel.

  • Patent number: 8299908
    Abstract: A tire pressure monitoring system distinguishes a mounted tire from a non-mounted tire, and which automatically changes over IDs and tire-pressure thresholds without any exclusive apparatuses. A tire pressure monitoring unit stores an identification code of a tire pressure sensor unit and a tire-pressure set value as a pair. While a vehicle is traveling at a speed equal to or faster than a predetermined vehicle speed, if an identification code received within a predetermined time coincides with any one of identification codes of registered tires and the number of coinciding identification codes is equal to the number of tires, and, at least one of the coinciding identification codes is an identification code other than specified identification codes, the specified identification codes are replaced with those coinciding identification codes which are newly specified as respective identification codes of tire pressure sensor units mounted in tires mounted on the vehicle.
