Abstract
In order to mitigate a need for reprogramming tire pressure sensors after tire rotation, tire change, etc., all sensors on a vehicle are preprogrammed with a lookup table that correlates modulation frequency to axle and wheel end positions on the vehicle. Dual antenna initiator coils are mounted to a vehicle such that each wheel end has one directional antenna directed toward it. Each initiator coil is programmed to modulate its transmission frequency by a predetermined modulation frequency such that each antenna transmits using a different modulation frequency. Each sensor receives a modulated signal, identifies the modulation frequency, and performs a table lookup to determine its axle and wheel end location. The sensor transmits its identified wheel end and axle location to a controller unit along with tire pressure status information for its wheel.
