The invention provides a control method and device for the sliding friction torque of a clutch and electronic equipment. The control method for the sliding friction torque of the clutch comprises the steps of expressing and storing a strong nonlinear relation between the clutch sliding friction torque and multiple influence factors through a neural network model; and acquiring clutch target sliding friction torque and the values of influence factors of the clutch target sliding friction torque, and enabling the neural network model to output corresponding clutch target pressure accordingly so as to calculate electromagnetic valve target current to control the clutch. According to the method, more complete clutch sliding friction torque characteristics are expressed by using a smaller storage space, and the storage space is greatly reduced; and online self-learning is performed on the complex torque characteristics of the clutch by using the characteristics of the neural network so as to adapt to the individual deviation of clutch assembly manufacturing and assembling and the performance change after long-term use.
Description
technical field [0001] The invention relates to the technical field of clutch control, in particular to a control method, device and electronic equipment for clutch slipping torque. Background technique [0002] Wet clutches are widely used in conventional automatic transmissions as well as in dedicated hybrid transmissions. Through the wet clutch, not only can different transmission ratios be realized, but also the locking and disengaging of the engine and gearbox can be realized. [0003] As people's requirements for driving comfort are getting higher and higher, the control of wet clutch slip torque also needs to be more and more precise. In the TCU (transmission controller), usually the target slipping torque of the wet clutch is first converted into the target pressure of the wet clutch, and then the target current of the solenoid valve is calculated according to the target pressure. The slipping friction of wet clutch is a typical tribological problem. The slipping t...
