Engaging control method and engaging control device for clutch of hybrid automobile

Abstract

The invention provides an engaging control method and an engaging control device for a clutch of a hybrid automobile. The method comprises the following steps of: receiving a clutch engaging control instruction; in the clutch engaging process of the first time period, controlling the torque of a motor constant; simultaneously controlling an engine to maintain an idle speed operating condition; after clutch engaging is finished, controlling the target torque of the engine to increase in a first first-order filtration curve within the second time period, and simultaneously controlling the torque of the motor constant; and controlling the torque of the motor to decrease in a second first-order filtration curve within the third time period after the second time period. By utilizing the engaging control method and the engaging control device, the power output of vehicles can be smoothly switched from a state that the motor serves as main power to a state that the engine serves as main power, so that vehicle impact during the model clutch engaging process is reduced, and the driving comfort can be improved.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a clutch engagement control method for a hybrid electric vehicle, an engagement control device thereof, and a hybrid electric vehicle including the engagement control device. Background technique [0002] As the international community pays more and more attention to energy security and environmental protection issues, countries have increasingly stringent requirements on vehicle emissions. Reducing dependence on energy and realizing energy conservation and emission reduction has become an urgent problem to be solved for the sustainable development of the world economy. Therefore, hybrid electric vehicles and pure electric vehicles have become the development trend of today's automobile industry. Among them, the gasoline-electric hybrid vehicle combines the motor and the engine, and sets idle stop, motor start, intelligent charging, regenerative braking, motor a...
