Disclosed are an apparatus and a method for calculating a wheel velocity signal and a wheel acceleration signal. According to one embodiment of the present invention, the apparatus for calculating a wheel velocity signal and a wheel acceleration signal comprises: an input unit for receiving a driving signal of an antilock brake system (ABS) device, and receiving a wheel velocity signal and a wheel acceleration signal sensed by a sensing device; a calculation unit for applying the received wheel velocity signal and wheel acceleration signal to a Kalman filter model when the driving signal of the ABS device is received so as to calculate a current final measurement value of the wheel velocity signal and a current final measurement value of the wheel acceleration signal, which are updated while noise signals are removed in real time by the Kalman filter model; and a control unit for controlling the ABS device to receive the calculated current final measurement value of the wheel velocity signal and the calculated current final measurement value of the wheel acceleration signal so as to drive the same.
