Summary:

The switching and coupling of the power source during mode switching of hybrid continuously variable transmission (CVT) vehicles lead to interruptions and sudden changes in power system output torque, which is a key factor affecting driving comfort. To address this issue, the following steps were taken: Firstly, based on the logical threshold energy management strategy, the conditions for mode switching in hybrid CVT vehicles were analyzed. Next, a dynamic model of the clutch engagement process was established, and a double fuzzy PID control strategy for engine speed and clutch pressure was formulated. Then, a dynamic coordination control strategy, combining "engine speed and clutch pressure double fuzzy PID control" with coordinated control of motor torque, was proposed. Finally, the proposed control strategy was simulated and verified. The aim of this approach is to mitigate interruptions and sudden changes in power system output torque during mode switching, thereby improving driving comfort in hybrid CVT vehicles
