A slip prevention system of a vehicle and a control method thereof are provided to control braking force of the system according to the amount of creep torque at the time the vehicle starts, thereby ensuring stable start. A slip prevention system(50) of a vehicle comprises a brake switch(10), a vehicle speed sensor(20), an accelerator position sensor(30), and a control portion(40). The brake switch detects whether or not a brake pedal is in operation. The vehicle speed sensor detects the current vehicle speed from the revolution number of an output axle gear in a transmission. The accelerator position sensor detects displacement of an accelerator pedal. The control portion determines whether stop condition has been converted into starting condition after analyzing information on the brake switch, the vehicle speed sensor and the accelerator position sensor. If converted, the control portion operates the slip prevention system to achieve additional braking force.
