Tire location registration algorithm using inter frame spacing pattern in TPMS

Recently, vehicle safety has become very important in the automobile industry. TPMS(tire pressure monitoring system) is also one of the vehicle safety systems. Recent studies of TPMS are proceeding in the fields of low power operation, battery-less system, and tire location registration. In this paper, we analyze the conventional tire location registration algorithms in which the simplex communication is used. And we propose a new algorithm that uses Inter Frame Spacing Pattern to identify the location of each tire. By implementing TPMS with proposed tire location registration algorithm, we confirmed that all sensors are registered normally within about 3 minutes.
