Apparatus and Method For Changing Frequency Deviation

摘要

A protocol to be used in the transmission is determined. Based upon the protocol, the transmission frequency range of a clock is selectively altered. TPMS data is transmitted according to the altered transmission frequency range of the clock.

1. A method for transmitting tire pressuring monitoring system (TPMS) data, comprising,
determining a first protocol to be used in the transmission of tire pressure monitoring data from a transmitter; based upon the first protocol, selecting a first deviation between a first high frequency that is used to transmit a logic one and a first low frequency to transmit a logic zero; transmitting the tire pressure monitoring system (TPMS) data according to the first high frequency when there is a logic one and first low frequency when there is a logic zero; subsequently determining a second protocol to be used in the transmission of tire pressure data from a transmitter; based upon the second protocol, selecting a second deviation between a second high frequency that is used to transmit a logic one and a second low frequency to transmit a logic zero; wherein the first deviation is different than the second deviation; transmitting TPMS data according to the second high frequency when there is a logic one and second low frequency when there is a logic zero.
