ROBUST RADIO FREQUENCY SIGNALS

摘要

A tire pressure monitoring system includes a receiver for processing signals and alerting an operator of the vehicle should conditions within any of the tires fall outside a desired range. The transmitters within the tires emit shorter transmission signals during operation by eliminating transmission of the identification code. The receiver stores the identifier for each transmitter for comparison to subsequent transmissions. Subsequent transmissions do not include the identifier. The receiver combines the saved identifier with the value provided in the check portion of the incoming transmission. If the combination of the saved identifier with the value provided in the check portion meets a defined criteria, than the signal is recognized as originating from one of the transmitters.
