Abstract
A method for monitoring tire pressure of a system is disclosed. The method includes the steps of detecting a signal other than that of an in-use tire pressure signals and in response to the detection of the signal, maintaining the proper reception of the in-use tire pressure signals by a receiver.
Claims23
A method for monitoring tire pressure of a system, comprising the steps of:
- detecting an interfering signal that is a signal other than that of in-use tire pressure signals;
- maintaining the proper reception of the in-use tire pressure signals by a single receiver when the interfering signal is detected;
- initializing the system with a learned signal strength envelope for differentiating the interfering signal and the in-use tire pressure signals;
- measuring a signal strength of the in-use tire pressure signals;
- and
- differentiating between the interfering signal and the in-use tire pressure signals based upon a measured signal strength indicator of the in-use tire pressure signals.

A method for monitoring tire pressure of a system, comprising the steps of:
- propagating an interfering signal from a nearby vehicle to a vehicle including a tire pressure monitoring system;
- detecting that the interfering signal is not originating from an in-use tire associated with in-use tire pressure signals for the tire pressure monitoring system;
- maintaining the proper reception of the in-use tire pressure signals by a single receiver when the interfering signal is detected;
- propagating a signal from a spare tire;
- detecting when the in-use tire is replaced with the spare tire;
- and
- automatically updating a location of one of the in-use tire and the spare tire.

A method for monitoring tire pressure of a system, comprising the steps of:
- propagating an interfering signal from a spare tire stowed about a vehicle including a tire pressure monitoring system;
- detecting that the interfering signal is not originating from an in-use tire associated with in-use tire pressure signals for the tire pressure monitoring system;
- maintaining the proper reception of the in-use tire pressure signals by a single receiver when the interfering signal is detected;
- detecting when the in-use tire is replaced with the spare tire;
- and
- automatically updating a location of one of the in-use tire and the spare tire.
