[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and implementation examples.
[0015] Such as figure 1 Shown, the present invention is a kind of dynamic coordinated control method of hybrid electric vehicle shifting process based on motor speed closed-loop control. Automatic transmission (AMT) 4, final drive 5, inverter 6 and power battery 7, etc. Wherein, the main motor 2 is arranged at the rear end of the automatic transmission 4 and is connected to the wheels through the final reducer 5 , and the auxiliary motor 3 is connected to the front end of the engine 1 .
[0016] Such as figure 2 As shown, the method of the present invention includes three parts: the entry control logic, the dynamic coordination control strategy of the shift process and the exit control logic. The present invention mainly adds the content of closed-loop control to the main motor speed in the dynamic coordination control strategy of the s...
