Background technique

In the existing technology, hybrid vehicles are usually developed based on multiple drive modes, and the hybrid architecture drive mode is one of multiple drive modes. The hybrid architecture usually uses a planetary gear scheme.

Switch to meet the driver's power and comfort requirements.

The preset steps for the upshifting and downshifting process include: shifting out of gear - speed synchronization - shifting into gear - restoring torque. However, in the hybrid architecture driving mode of the planetary gear scheme, the smoothness of shifting is poor when the throttle is used for rapid acceleration and deceleration. The synchronization time of the shifting speed is long, and sluggishness and gear stagnation are prone to occur. For example, when the vehicle accelerates sharply, the vehicle speed rises quickly, and the rotating shaft speed is high; then it decelerates sharply, the vehicle speed drops quickly, and the target gear requires a downshift, and the rotating shaft speed decreases rapidly with the vehicle speed. At this time, the engine speed cannot be accelerated The speed drops to reach the shifting target speed, and the synchronization time is too long, causing the gear to jam; the engine has a load torque, and the torque is greater than the shifting force, resulting in the inability to enter the gear.
