Tire pressure monitoring system with a signal initiator

摘要

A tire pressure monitoring system (12) for a vehicle (10) has a plurality of tires (14a-d) in respective rolling locations having a respective plurality of tire transmitters (16a-d) that generate a respective plurality of transmitter identification signals. A respective plurality of initiators (20a-d) are fixedly attached to the vehicle at a respective plurality of locations. A controller (22) activates the plurality of initiators (20a-d) by generating a respective plurality of initiator signals from the plurality of initiators. The plurality of initiator signals has a first power level. The controller (22) increases the first power level incrementally to a final power level until the controller receives a sensor signal from each of the plurality of tire transmitters.
