Tire pressure monitoring system
First Claim
Patent Images
1. A tire pressure monitoring system for a vehicle comprising:
- a sensor module configured to consume power and transmit a first signal having a first signal strength;
a receiver configured to receive the first signal and to determine the first signal strength; and
a transmitter in communication with the receiver;
wherein the receiver is configured to cause the transmitter to send a second signal for the sensor module if the first signal strength is more than a desired signal strength and wherein the sensor module reduces the power it consumes in response to the second signal;
wherein the receiver is further configured to cause the transmitter to send a third signal to the sensor module, and wherein the sensor module transmits the first signal in response to receiving the third signal, and wherein the receiver is further configured to cause the transmitter to increase its power consumption if the receiver does not receive the first signal within a predetermined period of time after the receiver causes the transmitter to send the third signal to the sensor module.

Abstract
A tire pressure monitoring system may adjust the power it consumes. In at least one embodiment, the system includes a receiver that receives a first signal having a signal strength, determines the signal strength, and causes a second signal to be sent if the signal strength is more than a desired signal strength.

9. A tire pressure monitoring system for a vehicle comprising:
-
a sensor module configured to consume power and transmit a first signal having a signal strength; and a transceiver configured to receive the first signal, to determine whether the signal strength is more than a desired signal strength, and to transmit a second signal for the sensor module if the signal strength is more than the desired signal strength; wherein the sensor module reduces the power it consumes in response to the second signal; wherein the transreceiver is further configured to send a third signal to the sensor module, and wherein the sensor module transmits the first signal in response to receiving the third signal, and wherein the transceiver is further configured to increase its power consumption if the transceiver does not receive the first signal within a predetermined period of time after the transceiver sends the third signal to the sensor module. - View Dependent Claims (10, 11, 12, 13, 14, 15)
