“…Pada penelitian tersebut digunakan gabungan metode analisa radius relative ban dan analisa vibrasi untuk menentukan sensitifitas yang optimal mendeteksi penurunan tekanan (pressure losses) ban pada kondisi yang berbeda. Penelitian lain aplikasi TPMS dilaporkan pada makalah [6][7] [8], peneliti pada [6] melakukan deteksi perubahan frekwensi resonansi torsi jika tekanan ban menurun. Tekanan ban dimonitor berdasar sinyal-sinyal kecepatan ban pada Anti-lock Braking System (ABS).…”

“…When tire pressure decreases, the vertical stiffness of the tire drops, and the amount of sinking increases. Hence, the vertical deflection of the tire increases, then the wheel rolling speed becomes correspondingly lower [15]. The measurement of tire stiffness is very difficult with a sensor, thus vertical tire stiffness is obtained by the other tire parameters measured directly with sensors.…”

“…Instead, another dynamic parameter of tire must be used for indirect TPMS. The most important parameters are longitudinal tire force and vertical deflection of tire [15]. In this study, vertical tire deflection is used for estimating the changes in tire pressure.…”

“…In this study, vertical tire deflection is used for estimating the changes in tire pressure. Because this parameter determines the variations in vertical stiffness of tire through deformation and deflection of tire which represent the changes in tire pressure in best way [9,15]. The most effective way is to occur resonance frequencies of vertical tire deflection for applying to TPMS.…”

This study aims to experimentally investigate accordance between tire pressure and vertical deflection of tire in order to use in TPMS (Tire Pressure Monitoring System). For this aim, the resonance frequency of vertical deflection of tire is determined by using test results. Thus, the road tests have been conducted on dry flat road for measuring the tire deflection. These tests are run at constant vehicle speeds 30 and 100km/h for tire pressures 15, 20, 25, 30, 35psi. Therefore, the vertical deflection changes have been measured under same road conditions with different vehicle speeds. The frequency responses of the measured vertical deflections are obtained by implementing sampled root mean square (SRMS) method to vertical deflection signals. The resonance frequency of the vertical deflection is taken from the frequency responses. The results show that the accordance between tire pressure and vertical deflection of tire is achieved irrespective of the changes in vehicle speed. Consequently, the algorithm to detect the drops in tire pressure is developed by using the time and frequency domain results.
