Abstract: Provided are a hybrid power vehicle range extender power following control method and system. The method includes: when a vehicle satisfies range extender power closed-loop control conditions, an actual charge-discharge power of a power battery and a charge-discharge power expectation value of the power battery are taken as control errors to adjust a total range extender electric power requirement, an engine torque requirement is calculated according to the total range extender electric power requirement, and an engine is controlled to perform the engine torque requirement; and when it is detected that a drive motor electric power suddenly changes and/or a load power suddenly changes, engine quick torque control is activated, and an engine quick torque requirement is taken as a feed-forward value of a generator speed setting controller to control a generator.

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.
