    摘要: A wireless tire pressure sensing system based upon a Schrader valve design is provided. The system includes a valve body, a valve pin and a compression element for sealing engaging the valve body and the valve pin to maintain tire pressure. A pressure sensing device mounted within the valve body and connected to valve pin senses the pressure within the tire and provides its signal to the valve pin. The valve pin is adapted as a component of an antenna that transmits a wireless pressure signal to a remote receiver/transmitter mounted on the vehicle. The receiver/transmitter transmits a corresponding signal to a vehicle control system that generates a warning signal when the tire pressure is below a threshold safety value.
