In the present invention, signals are received from a plurality of wheel speed sensors, a reverse gear sensor, and a brake sensor. Errors of the wheel speed sensors are estimated using the received signals, a signal having a corrected error is obtained using the estimated errors, linear interpolation and band-pass filtering processing are performed on the signal, a tire resonant frequency is estimated using the processed signal, tire pressure is estimated based on the estimated resonant frequency, and whether or not to generate an alarm is determined based on the calculated tire pressure. Accordingly, there is an advantage in that whether or not pressure within a tire of a vehicle is abnormal can be determined in a cheap calculation device for a short time using a conventional wheel speed sensor.

A pump that is independent of and pneumatically parallel to the vehicle air supply includes an inlet and an outlet. The pump inlet receives air from atmosphere, the pump compresses the air, and the pump outlet is fluidly connected to the pneumatic conduit.

    Abstract: This wheel has features allowing both integrated and non-integrated Central Tire Inflation (CTI) systems to be installed, without the need for a specialized manifold, adapter, or unique wheel to accommodate each specific system.

In addition, a wheel with both integrated and non-integrated Central Tire Inflation (CTI) systems is much simpler to assemble since the valve mounts directly to the wheel and no brackets are required, unlike prior two-piece bolt-together wheels.

  • Patent number: 7963307
    Abstract: A tire inflation system comprising pneumatically controlled wheel valves that are situated in the wheels of a motor vehicle. An electrically actuated pilot valve that is fixed to the vehicle controls the respective wheel valves. To produce a small, low-cost, reliable tire inflation system, a first and a second compressor are provided. The first compressor supplies a first compressed air system with medium-pressure compressed air and the second compressor supplies a second compressed air system with high-pressure compressed air. The wheel valves are situated in the first compressed air system and the pilot valves are situated in the second compressed air system.

  • Patent number: 7909076
    Abstract: A tire pressure control system for a tire mounted to a wheel of a vehicle is disclosed. The tire pressure control system comprises a servo system mounted to the wheel that includes a servo mechanically connected to a vent valve that is in fluid communication with a gas inside the tire. The vent valve is adapted for bleeding the gas out of the tire and into the ambient atmosphere. A pressure sensor is in fluid communication with the gas inside the tire, and a control circuit is electrically connected to the servo and the pressure sensor. The control circuit further includes a signal receiving means and a memory for storing a commanded pressure signal. The control circuit actuates the servo to open the vent valve when the pressure sensor indicates a tire pressure of greater than the commanded pressure. A master control unit is adapted to transfer the commanded pressure signal to the control circuit through a transmission means.

  • Publication number: 20100230023
    Abstract: An apparatus for controlling tire inflation pressure includes an outlet side end portion of a supplying passageway opened on an outer circumference of a column-shaped boss portion provided in an axle, and an inlet side end portion of an introducing passageway that is opened on an inner circumference of an annular hub portion provided in a wheel. A wheel is mounted onto the axle. The inner circumference of the annular hub portion is engaged with the outer circumference of the column-shaped boss portion, and thereby the outlet side end portion and the inlet side end portion are communicatively connected to each other air tightly. Thus, easiness in mounting a vehicle wheel assembly relative to the axle can be improved.

  • Publication number: 20100078109
    Abstract: A vehicle tire inflation system includes an air supply that is connected to a vehicle tire by a pneumatic conduit. A pump that is independent of and pneumatically parallel to the vehicle air supply includes an inlet and an outlet. The pump inlet receives air from atmosphere, the pump compresses the air, and the pump outlet is fluidly connected to the pneumatic conduit. When the air pressure in the pneumatic conduit drops below a predetermined level, compressed air from the pump is introduced into the pneumatic conduit, thus increasing the air pressure in the conduit to increase the air pressure that is available to the tire. A reservoir tank, which is also independent of the vehicle air supply, may be in fluid communication with the pump outlet and the pneumatic conduit.
