TIRE PRESSURE MONITORING SENSOR WITH CHANGING FUNCTIONALITY BASED UPON VEHICLE ACTION
First Claim
1. A method of monitoring tire pressure of a plurality of wheel units of a vehicle, comprising the steps of:
- detecting at a tire pressure monitoring sensor an incoming transmission rate for an incoming transmission;
in response to detecting the incoming transmission rate is greater than zero, transmitting a first outgoing transmission at a first outgoing rate;
in response to detecting the incoming transmission rate is substantially zero, transmitting a second outgoing transmission at a second outgoing rate.

Abstract
A tire pressure monitoring system includes a plurality of tire pressure monitoring sensors including low frequency wireless receivers and high frequency wireless transmitters. The system further includes a plurality of low frequency transmitters each being disposed proximate one of the plurality of tire pressure monitoring sensors. The system further includes a control module in communication with the plurality of tire pressure monitoring sensors through the plurality of low frequency transmitters. In a first phase of operation the control module causes the low frequency transmitters to transmit low frequency wireless signals to the tire pressure monitoring sensors causing the tire pressure monitoring sensors to transmit data to the control module at a rate. In a second phase or operation the tire pressure monitoring sensors transmit data to the control module at a second rate.

17. A tire pressure monitoring sensor, compromising:
-
a pressure sensor configured to generate tire pressure data; a receiver; a transmitter; and a central processing unit coupled the pressure sensor, the transmitter, and the receiver, the central processing unit configured to detect an incoming transmission rate for an incoming transmission received at the receiver, the central processing unit further configured to cause the transmitter to transmit the tire pressure data at a first outgoing rate in response to detecting an incoming transmission rate greater than zero, the central processing unit further configured to cause the transmitter to transmit the tire pressure data at a second outgoing rate in response to detecting an incoming transmission rate substantially equal to zero. - View Dependent Claims (18, 19)

20. A non-transient computer usable medium having a computer readable program code embodied therein, the computer readable program code adapted to be executed to implement a method of monitoring tire pressure of a plurality of wheel units of a vehicle, the method comprising:
-
detecting at a tire pressure monitoring sensor an incoming transmission rate for an incoming transmission; in response to detecting the incoming transmission rate is greater than zero, transmitting a first outgoing transmission at a first outgoing rate; in response to detecting the incoming transmission rate is substantially zero, transmitting a second outgoing transmission at a second outgoing rate.
