The invention discloses a motor braking and friction braking integrated system and a control method thereof. The system mainly comprises a friction braking device and a motor braking device, a braking disc of the friction braking device and a generator of the motor braking device are installed on a supporting shaft, and the braking disc is connected with a permanent magnet of the generator in a fastened mode. When an automobile is braked, the friction braking device works independently, and the motor braking device brakes the automobile further according to the slip rate of wheels. When the motor braking device acts, kinetic energy generated when the automobile is driven drives the braking disc and the permanent magnet connected with the braking disc in the fastened mode to rotate, in this way, an alternating magnetic field is generated on a coil on the periphery of the permanent magnet to generate power, and the electric energy is stored inside a storage battery. The two braking devices can be effectively integrated, in combination with the slip rate of the wheels, the braking effect of the automobile can be reliably ensured, and the purpose of storing the energy is achieved.
