Abstract :
The tire pressure has significant influence on the safety and the energy/fuel consumptions of the vehicles. Therefore the Tire Pressure Monitoring Systems and the related methods are one of the most evolving areas. The aim of the research is to analyze how can be increased the efficiency of the frequency analyzing based tire-pressure monitoring systems with the application of distinct signal processing methods. Based on the literature survey various techniques were selected to deeper examination such as Fast Fourier (FFT), Fast Cosine (FCT), Fast Cohen-Daubechies-Feauveau (CDF) 9/7 Wavelet and the Fast Haar Transforms; and a Wavelet and a Haar Transform based method have been introduced to estimate efficiently the eigenfrequency.
