The present invention provides a clutch coupling coordination control method for a hybrid hybrid power system, comprising step 10, before the clutch is coupled, using the engine to control the rotational speed, and the ISG motor to control the torque; and step 20, judging the absolute value of the rotational speed difference between the ISG motor and the drive motor Whether it is less than or equal to n0, if so, switch to using the engine to control the torque, and the ISG motor to control the speed; if not, return to step 10; step 30, judge whether the absolute value of the speed difference between the ISG motor and the driving motor is less than or equal to n1 and the duration is T1 , yes, then give the clutch engagement command; no, return to step 20; step 40, judge whether the absolute value of the speed difference between the ISG motor and the driving motor is less than or equal to n2 and last for T2, if yes, the clutch engagement is completed; no, Then return to step 30. The invention can speed up the speed regulation process before the clutch is combined, reduce the charge and discharge current of the battery during the speed regulation process, and prevent the battery from heating up too fast or even from overheating.
