The present invention relates to a vehicle mass estimating apparatus and method using wheel speed. The vehicle mass estimating apparatus receives a wheel speed of a vehicle to calculate a frequency corresponding to the wheel speed and estimate mass of the vehicle associated with the calculated frequency. The present invention provides the vehicle mass estimating apparatus comprising a resonance frequency calculator for receiving wheel speed information from at least one wheel speed sensor provided in a vehicle and calculating a resonance frequency in at least two directions, and a mass estimator for estimating mass of the vehicle using the ratio of the resonance frequencies in two directions in the resonance frequency calculator.

    본 발명은 차량에 구비된 휠 속도를 입력받아 상기 휠 속도에 따른 주파수를 산출하고 산출된 주파수와 연계된 차량의 질량을 추정하는 것을 특징으로 하는 휠 속도를 이용한 차량 질량 추정 장치 및 방법에 대한 것이다. 본 발명은, 차량에 구비된 적어도 하나의 휠 속도 센서로부터 휠 속도 정보를 입력받아 적어도 두 방향에 따른 공진 주파수를 산출하는 공진 주파수 산출부; 및 상기 공진 주파수 산출부에서 상기 두 방향에 따른 공진 주파수의 비율을 이용하여 상기 차량의 질량을 추정하는 질량 추정부를 포함하는 차량 질량 추정 장치를 제공한다.
