Abstract

The invention provides a control method and a control device for an automatic transmission clutch and relates to the technical field of transmission control. The control method for the automatic transmission clutch comprises the following steps: detecting a change value of an accelerator pedal; when the change value of the accelerator pedal is smaller than a preset threshold value, sending a signal to a controller by an engine, and controlling the clutch by the controller according to a torque value of the engine, wherein the clutch pressure changes; when the change value of the accelerator pedal is equal to greater than the preset threshold value, sending the signal to the controller by the engine, and carrying out compensation control to the clutch pressure by the controller according tothe throttle opening of the engine. The control method solves the technical problem of unstable operation in a working condition that the accelerator pedal is deeply pedaled or is suddenly loosened to accelerate or decelerate rapidly during gear shifting in driving in the prior art. By way of throttle opening compensation, hysteresis of the actual pressure and the target pressure of a hydraulic system of the clutch is matched with that of the actual torque and the throttling opening of the engine, so that a good gear shifting quality is achieved.

Description

technical field [0001] The invention relates to the technical field of transmission control, in particular to a control method and device for an automatic transmission clutch. Background technique [0002] With the development of social economy, the emergence of various means of transportation has facilitated people's travel, such as bicycles to achieve people's short-distance travel, buses to achieve people's stops at a certain station, and cars as people's travel tools. Users can drive according to their own needs, and can quickly arrive from one point to another without transferring or reversing, which provides convenience for people's travel. As a result, more and more people begin to choose cars as a means of travel. [0003] When the car is running, it mainly relies on the transmission. The transmission transmits the output power of the engine in the form of different speeds and torques, while a series of actions such as starting or shifting operations of the automatic...
