Apparatus and method for automatically recognizing position of wheel of vehicle

摘要

Disclosed herein are an apparatus and a method for automatically recognizing a position of a wheel of a vehicle. The apparatus includes a rotation sensor unit sensing a variation in rotation of the wheel of the vehicle; a pressure sensor unit sensing a rate of variation in pressure of the wheel of the vehicle; and a sensor control unit judging the position of the wheel of the vehicle by the variation in rotation and the rate of variation in pressure obtained from the rotation sensor unit and the pressure sensor unit. The sensor control unit judges the position of the wheel of the vehicle by dw/dt x dp/dt, in which dw/dt is the variation in rotation and dp/dt is the rate of variation in pressure. The wheel is judged as a front wheel when a value of dw/dt x dp/dt has a negative (-) sign and the wheel is judged as a rear wheel when the value of dw/dt x dp/dt has a positive (+) sign.
