Abstract
Official abstract text for this publication.
The present invention relates detecting the conditions of tires for a vehicle. In the present invention, signals are received from a plurality of wheel speed sensors, a reverse gear sensor, and a brake sensor. Errors of the wheel speed sensors are estimated using the received signals, a signal having a corrected error is obtained using the estimated errors, linear interpolation and band-pass filtering processing are performed on the signal, a tire resonant frequency is estimated using the processed signal, tire pressure is estimated based on the estimated resonant frequency, and whether or not to generate an alarm is determined based on the calculated tire pressure. Accordingly, there is an advantage in that whether or not pressure within a tire of a vehicle is abnormal can be determined in a cheap calculation device for a short time using a conventional wheel speed sensor.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for detecting conditions of tires for a vehicle, comprising: a plurality of wheel speed sensors configured to generate signals corresponding to rotation speeds of the tires; a reverse gear sensor configured to generate a signal when a reverse gear operates; a brake sensor configured to generate a signal when a brake pedal operates; a control unit configured to receive the signals from the plurality of wheel speed sensors, the reverse gear…
