ABSTRACT:
An automotive tire pressure monitor with diversity antenna system employs a RF transmitter within each wheel/tire assembly and a vehicle mounted receiver with multiple receiving antennas. A first, primary antenna is located adjacent one vehicle window and a secondary antenna is located adjacent another vehicle window opposite the primary antenna. Both antennas are coupled to a receiver via a switch. The receiver feeds a processor, which is encoded to select the optimal antenna/receiver configuration based upon absolute signal strength (signal to noise), signal quality (completeness of encoded data) or signal reception rate. The signal received from the optimized antenna/receiver configuration is processed and transmitted to the host vehicle for system intervention and or display to an operator.
