ABSTRACT:
An antilock brake control method for a four-wheel drive vehicle including calculating an estimated vehicle speed on the basis of a wheel speed of a wheel and a value obtained by adding an offset value to an output from a longitudinal acceleration/deceleration sensor for detecting a longitudinal acceleration or deceleration of the vehicle. When it is detected that all of the four wheels are in their spinning state, the addition of the offset value to the output from the longitudinal acceleration/deceleration sensor is stopped, and the estimated vehicle speed is calculated on the basis of the wheel speed and the output from the longitudinal acceleration/deceleration sensor.
