The present invention relates to a vehicle speed estimation method, and a vehicle speed estimation system. The vehicle speed estimation system comprises: a longitudinal acceleration sensor sensing a longitudinal acceleration signal of a vehicle; one or more wheel speed sensors sensing a wheel speed signal of the vehicle; and a control unit estimating a dynamic radius of a tire based on the longitudinal acceleration signal and the wheel speed signal and estimating the driving speed of the vehicle using the estimated dynamic radius of the tire. The present invention estimates the dynamic radius of the tire of a vehicle wheel using the wheel speed sensor and the longitudinal acceleration sensor to be used for displaying the driving speed of the vehicle.
