The invention provides a decoupling control method for an automobile combined braking system. The combined braking system comprises a master controller and a slave controller, the master controller is installed in the Y-booster, and the slave controller is installed in the ESC. The main controller receives a braking request and Y-Booster motor parameters, the braking request comprises target braking parameters and a target braking type, and the target braking parameters comprise target braking pressure, motor target torque and braking pedal speed; the target braking parameters of the Y-Booster and the target braking parameters of the ESC are determined; according to the current of the Y-Booster motor, the actual braking parameters of the Y-Booster are observed; according to the target braking type, the actual braking parameters of the Y-Booster and the total actual braking parameters, the actual braking parameters of the ESC are obtained through calculation; according to respective target braking parameters and actual braking parameters of the Y-Booster and the ESC, the motor control moments of motors of the two mechanisms are determined; and the closed-loop control on the motor current is performed according to the motor control torque and the actual output torque of the motor. The control effect of the brake system is improved.
