A brake control method of an electromechanical flywheel hybrid power system belongs to the field of electric vehicle control and is characterized in that the hybrid power system can be controlled to operate in various brake modes according to states of a vehicle, a motor and a flywheel. Under low braking demand power, a second power source motor is controlled to participate in regenerative braking, and the braking energy recovery rate is increased; under the medium braking demand power, a first power source motor and the second power source motor are controlled to participate in regenerative braking of the vehicle, and the economy of vehicle driving and the continuous driving mileage of the vehicle are improved; and under the high braking demand power, a controller controls the first powersource motor, the second power source motor and the flywheel to jointly participate in regenerative braking of the vehicle, the running efficiency of a battery is improved, and the energy state of the flywheel is guaranteed.
