Example Embodiment

[0045] In the clutch control, due to the manufacturing deviation of the clutch, the manufacturing deviation of the execution system, the wear and aging of the clutch during use, and the wide variety of use environments, it will cause the clutch to use a fixed control characteristic curve and cannot achieve accurate clutch control under all circumstances. control. The off-line self-learning of the gearbox or the self-learning of the clutch characteristic curve of simple variables used in the prior art cannot realize the high-precision control of the clutch in a complex environment.

[0046] In the embodiment of the present invention, the position S of the half-engagement point in the current engagement process of the clutch is obtained 1 , and the recorded half-engagement point position S during the last clutch engagement process 0 , and according to the half-binding site position S 1 For the half-binding site position S 0 Make corrections to obtain the corrected half-joint ...

Abstract

The invention discloses a hybrid power vehicle clutch control method and device. The method comprises the steps that the semi-engaged point position S1 of a clutch in the current-time engaging processand the recorded semi-engaged point position S0 in the last-time engaging process of the clutch are acquired; the semi-engaged point position S0 is corrected according to the semi-engaged point position S1, and the corrected semi-engaged point position S0' is obtained; a control characteristic curve of the clutch is corrected according to the semi-engaged point position S0'; and the torque transmitting capacity of the clutch is controlled according to the corrected control characteristic curve. By adopting the scheme, the torque transmitting capacity controlling accuracy of the clutch can beimproved.

Description

technical field [0001] The invention relates to the technical field of vehicle clutch control, in particular to a hybrid vehicle clutch control method and device. Background technique [0002] Hybrid Vehicle (Hybrid Vehicle) refers to a vehicle whose drive system is composed of multiple single drive systems that can operate simultaneously. The so-called hybrid vehicle generally refers to a hybrid electric vehicle (Hybrid Electric Vehicle, HEV), that is, a traditional internal combustion engine and an electric motor are used as power sources. [0003] The clutch control in the automobile automatic transmission is the key technology of automatic transmission shift control and hybrid power mode switching control. Whether the clutch control is fast and accurate directly affects the shifting quality and hybrid mode switching quality. [0004] Existing clutch control technology cannot realize high-precision clutch control in complex environments. After long-term use of automati...
