Abstract
A system and method for estimating a wheel speed of a vehicle are provided. The system includes a wheel speed sensor that detects a rotation speed of a wheel of the vehicle and a longitudinal acceleration sensor that detects a longitudinal acceleration of the vehicle. A controller converts the longitudinal acceleration to a wheel acceleration, compensates for the converted wheel acceleration based on a compensation value obtained using wheel speed information, integrates the compensated wheel acceleration, and calculates a wheel speed estimation value based on the integrated wheel acceleration.
