Method and system for calibrating a tire pressure sensing system for an automotive vehicle

A pressure monitoring system for an automotive vehicle having a plurality of tires in a predetermined tire location relative to the vehicle comprising:

• a plurality of tire pressure transmitters each having pressure sensor and a serial number associated therewith, each tire pressure transmitter having a unique serial number;
• an EM calibration device having a transmitting range, said EM transmitting device having an actuator, said actuator when activated generating a calibration signal within said transmitting range;
• wherein said calibration signal causing one of said plurality of tire pressure transmitters to EM transmit said serial number,
• a controller EM coupled to said pressure transmitter, said controller sequentially receiving said serial numbers and associating said serial numbers with said tire location of said vehicle.

A method of operating a pressure monitoring system comprising:

• generating an EM calibration signal from a transmitter;
• transmitting calibration information from a tire pressure sensor in response to said EM calibration signal;
• and
• receiving said calibration information in a controller.

A method of operating a pressure monitoring system comprising:

• positioning an EM calibration device within a predetermined distance from a first pressure transmitter in a first location;
• generating a first EM calibration signal from the EM calibration device;
• transmitting first calibration information from a first pressure sensor to a controller in response to said EM calibration signal;
• storing the first calibration information associated with said first location in a calibration memory;
• positioning the EM calibration device within the predetermined distance from a second pressure transmitter in a second location;
• generating a second EM calibration signal from the EM calibration device;
• transmitting second calibration information from a second pressure sensor to the controller in response to said second EM calibration signal;
• storing the second calibration information associated with said second location in the calibration memory;
• positioning the EM calibration device within the predetermined distance from a third pressure transmitter in a third location;
• generating a third EM calibration signal from the EM calibration device;
• transmitting third calibration information from a third pressure sensor to a controller in response to said third EM calibration signal;
• storing the third calibration information associated with said third location in a calibration memory;
• positioning the EM calibration device within the predetermined distance from a fourth pressure transmitter in a fourth location;
• generating a fourth EM calibration signal from the EM calibration device;
• transmitting fourth calibration information from a fourth pressure sensor to a controller in response to said fourth EM calibration signal;
• storing the fourth calibration information associated with said fourth location in a calibration memory.
