Antiskid control apparatus

摘要

An antiskid control apparatus for vehicles having a part-time four-wheel drive mode. The antiskid control apparatus calculates an average front wheel speed and an average rear wheel speed. A difference between the average front wheel speed and average rear wheel speed is determined, and is filtered to obtain a smoothed wheel speed difference value. Based on the value of the smoothed wheel speed difference value, a determination is made whether the vehicle drive state is the two-wheel drive state or four-wheel drive state. The antiskid control of the vehicle is switched between two-wheel control and four-wheel control in accordance with the determined vehicle drive state.
