Abstract
Provided is a control method and system for clutch engagement of a hybrid vehicle. The control method includes: when the hybrid vehicle meets a condition of adjusting a rotational speed of an engine, controlling the hybrid vehicle to enter a mode of adjusting the rotational speed of the engine, and determining a target rotational speed of the engine according to a rotational speed of a drive motor as well as transmission ratios of the engine and the drive motor to a drive wheel end and drive relationships of the engine and the drive motor with the drive wheel end; and when a difference value between the rotational speed of the engine and the target rotational speed of the engine is constantly smaller than a threshold value within a set time, controlling a clutch of the hybrid vehicle to be engaged.
