Abstract
A tire pressure monitoring system (TPMS) for a vehicle, and related operating methods are provided. The TPMS includes a plurality of tire pressure sensors, each being configured to wirelessly transmit respective sensor signals, and a wireless receiver configured to wirelessly receive and process sensor signals transmitted by the tire pressure sensors. The location of the wireless receiver is biased toward the fore or aft of the vehicle. The wireless receiver has an adjustable sensitivity setting that accommodates wireless signal reception in a key fob mode and a TPMS mode. One operating method for the TPMS involves wirelessly receiving sensor signals transmitted by the tire pressure sensors, determining respective received signal strength (RSS) values for the received sensor signals, and processing the RSS values to resolve whether the received sensor signals were transmitted by a fore tire pressure sensor or an aft tire pressure sensor.
