<p>#CMT# #/CMT# The device has a controller connected to a speed sensor and comprising an analyzing unit for carrying out frequential analysis of the speed sensor. A determination unit determines engine speed, and is connected to the controller, where the controller comprises a filter unit for frequential analysis of the speed sensor by utilizing the determined engine speed. The filter unit comprises multiple filter parts and a notch filter for filtering harmonics of the engine. #CMT# : #/CMT# An independent claim is also included for a frequential analysis method of a wheel speed sensor of a car. #CMT#USE : #/CMT# Analyzing device for use in a tire monitoring system (claimed) for frequential analysis of a wheel speed sensor of a car. #CMT#ADVANTAGE : #/CMT# The determination unit determines engine speed, and is connected to the controller that comprises the filter unit for filtering the harmonics of the engine, so that usage of the determination unit reduces additional resources for determination of the engine speed so as to improve reactivity of a tire monitoring system, thus reducing influences of harmonics during the frequential analysis. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation of a relationship between amplitude and frequency during frequential analysis.'(Drawing includes non-English language text)'.</p> |
