摘要
A system for indicating low tire pressure in vehicles, in which each vehicle wheel has a transmitter (100) with a unique code. A central receiver (200) in the vehicle is taught, at manufacture, to recognize the codes for the respective transmitters (100) for the vehicle, and also a common transmitter code, in the event one of the transmitters (102) needs to be replaced. During vehicle operation and maintenance, when the tires are rotated, the system can be recalibrated to relearn the locations of the transmitters. The transmitters (100) employ surface acoustic wave (SAW) devices (110). An application specific integrated circuit (ASIC) encoder (130) in each transmitter (100) is programmed at manufacture, in accordance with its unique code, to send its information at different intervals, to avoid clash between two or more transmitters (100) on the vehicle. The transmitters (100) are powered by long-life batteries.
