The invention relates to a compound braking system and a braking control system and a braking control method thereof. The compound braking control method comprises the following steps: (1) vehicle speed information and braking pedal openness information are acquired; (2) the total braking torque is calculated according to the information: the vehicle speed is higher, the total braking torque is greater; the braking pedal openness is larger, the total braking torque is greater; and (3) the vehicle is braked according to the total braking torque. The compound braking control system comprises a controller, a vehicle speed sensor and a braking pedal openness sensor; the controller is in sampling connection with the braking pedal openness sensor and the vehicle speed sensor; and the controller is used for calculating the total braking torque according to the acquired data. The compound braking system comprises the compound braking control system, an electric braking system and a frictional braking system. Two types of parameter information are synchronously acquired, so that the accuracy is higher. Meanwhile, the needed total braking torque is obtained through calculating, so that the braking comfort is correspondingly improved to a great extent.
