Abstract

The invention relates to the technical field of automatic gearboxes, in particular to a clutch control method, an automatic gearbox control unit and an automobile, wherein the clutch control method isapplied to the automatic gearbox control unit. The clutch control method comprises the following steps that the rotating speed of a gearbox input shaft and the rotating speed of an engine are obtained, the difference between the rotating speed of the gearbox input shaft and the rotating speed of the engine is calculated, and when the difference is greater than a preset value, an oil pressure reduction command is issued to a clutch in an automatic gearbox. Both the automatic gearbox control unit and the automobile adopt the clutch control method, and according to the clutch control method, theautomatic gearbox control unit and the automobile, engine emissions and the fuel cost are lowered.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a clutch control method, an automatic transmission control unit and an automobile. Background technique [0002] The automatic transmission with hydraulic torque converter does not need to be shifted to neutral due to the effect of the hydraulic torque converter before parking, but the engine needs to be extra based on the difference between the speed of the transmission input shaft and the engine speed during parking. Oil injection is used to make up for the drag torque of the hydraulic torque converter and maintain a stable idle speed, which will not only increase emissions, but also generate additional waste in terms of economy. [0003] To sum up, how to overcome the above-mentioned defects of the existing automatic transmission is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The object of the pre...
