Monitoring of tire pressure in motor vehicles with association of pneumatic module with wheel position, uses changing signal strength as pneumatic module rotates past offset sensor to compare to reference patterns

摘要

The tire pressure monitoring associates a pneumatic module with wheel position. Each module emits several signals with an identifier specific to the tire over a fixed duration. An antenna placed asymmetrically relative to the tire receives variable signal strength as the wheel rotates, compares variations to reference patterns, and performs the association when signals coincide.
