Problems solved by technology

[0004] However, when the clutch engages the engine and the drive motor, the clutch will be impacted by the engine and the drive motor for a long time, which will easily lead to damage to the clutch after multiple engagements and disengagements, reducing the service life of the clutch
[0005] Therefore, the current method of clutch engagement has the problem of damaging the clutch

Embodiment Construction

[0049] In order to make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

[0050] figure 1 It is a schematic flowchart of a method for engaging a vehicle clutch in an embodiment. The clutch engagement method provided in this embodiment can be applied to figure 2 In the application environment shown. Among them, a central controller (Central Control Unit, CCU) 101 is used to control the vehicle 102 to travel. The vehicle 102 may be a hybrid electric vehicle with an organic electrical coupling system (GAC-Mechatronic Coupling, GMC) deployed.

[0051] The electromechanical coupling system includes an engine 103, a clutch 104, a drive motor (Drive Control Unit, DCU) 10...

Abstract

The invention relates to a clutch engagement method and device of a vehicle, a power mode switching method and device of the vehicle, computer equipment and a storage medium. The clutch engagement method comprises the steps: controlling the clutch to enter a pre- engagement point from a separation point, and controlling the rotating speed difference between the two ends of the clutch to be reduced; and when the rotating speed difference between the two ends is reduced to the target rotating speed difference, controlling the clutch to enter an engagement point from the pre- engagement point, wherein the engagement point is used for coupling a engine and a driving motor through the clutch. By the adoption of the method, the problem that the clutch is prone to being damaged after multiple times of engagement and disengagement can be solved.

Description

Technical field [0001] This application relates to the field of vehicle technology, and in particular to a method and device for clutch engagement of a vehicle, a method and device for switching a power mode of a vehicle, computer equipment, and a storage medium. Background technique [0002] At present, hybrid vehicles using engines and drive motors as power sources are becoming more and more popular with users. [0003] In a hybrid electric vehicle, when the hybrid electric vehicle is in a pure electric drive mode or an extended-range drive mode, the clutch is in a disconnected state, and the engine and the drive motor are decoupled. When the hybrid electric vehicle switches to the hybrid mode, the clutch enters the engaged state from the disengaged state, and the engine and the drive motor are coupled to realize the hybrid output of the two powers. [0004] However, when the clutch is engaged with the engine and the drive motor, the clutch will suffer a long-term impact from the ...
