Zusammenfassung:	PURPOSE: An active front wheel steering device control method of a vehicle is provided to improve a braking safety on an asymmetry friction road including a different road friction coefficient of right and left wheels. CONSTITUTION: When a vehicle speed value sensed in a vehicle speed sensor; a front right and left wheel speed difference or a rear right and left wheel speed difference sensed in a wheel speed sensor; and yaw rate value sensed in a yaw rate sensor corresponds to a condition value for performing a split-M braking mode with a braking-on signal of a brake pedal sensor during a common driving mode of the vehicle, the split-M braking mode preventing sudden turning of the vehicle is performed by determining the situation in which the vehicle brakes in an asymmetry friction road including a different road friction coefficient.
