Apparatus and method for measuring rotation speeds of tires of vehicle

摘要

The present invention relates detecting the rotation speed 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. Accordingly, there is an advantage in that rotation speed of tires for a vehicle can be determined accurately.

1. An apparatus for measuring rotation speed of tires of a vehicle, the apparatus 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; and a control unit configured to receive the signals from the plurality of wheel speed sensors, the reverse gear sensor, and the brake sensor, to calculate a signal error-corrected by estimating an error of a wheel speed sensor, to perform linear interpolation, and to determine the rotation speed of the tires.
