Abstract:
A system (10) is provided for monitoring a remote tire monitoring sensor. The system includes a tire-based unit (16) having a sensor (42) and transmitter (44) that receives power from a power supply (18) located within the tire-based unit (16). The transmitter (44) transmits a signal (22) relating to a parameter measured by the sensor (42). The system (10) further includes a controller (36) that evaluates the life of the power supply (18) by monitoring energy usage of the power supply (18) by counting the number of occurrences in which the energy usage is above a prescribed amount (59) and comparing the number of occurrences to an energy threshold (60).
