The invention discloses a hybrid braking system of an electric wheel automobile and a control method thereof. The invention relates to the field of electric automobile brake systems. According to thehybrid braking system of the electric wheel automobile, on the premise that safety is guaranteed and the general braking function requirement of the electric automobile is met, the structure is simplified. The hybrid braking system comprises a hydraulic braking subsystem and a motor braking subsystem. The hydraulic brake subsystem comprises an oil storage cup, a brake pedal mechanism, a brake master cylinder, a pedal simulator, a public pipeline, a right brake wheel cylinder and a left brake wheel cylinder. The motor braking subsystem comprises a control unit and a pair of driving motors connected to the pair of driving wheels, the pair of driving motors are controlled through the control unit, and therefore the driving force and the braking force of the pair of driving wheels are adjusted. According to the system, the maximum total brake pressure requirement can be ensured. And the brake pedal feelings can be ensured to be consistent under different brake modes such as low-adhesion road surfaces, high-speed vehicle conditions and medium-low-speed vehicle conditions.
