Control system for continuously variable transmission, continuously variable transmission and automobile

Abstract

The invention relates to a control system for a continuously variable transmission, the continuously variable transmission and an automobile. The control system specifically comprises a basic layer and an application layer, wherein the application layer comprises a self-adaptive management layer, an interface layer, a gearbox scheduling layer, a function control layer and a hydraulic execution layer. From the perspective of data flow, the interface layer, the gearbox scheduling layer, the function control layer and the hydraulic execution layer are clear and smooth as a whole; and secondly, the layers are independently arranged, so that the layers are easier to expand and modify. Meanwhile, the self-adaptive management layer is used for carrying out self-adaptive comprehensive scheduling and management on parts corresponding to a first function module and a second function module of the function control layer and the hydraulic execution layer, so that the reliability of self-adaptive control is improved. In addition, the self-adaptive management module is used for carrying out unified management on the related parts, and a self-adaptive boundary is associated with the corresponding function layer, so that possible faults of hardware can be indirectly identified.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control system for a continuously variable transmission, a continuously variable transmission and an automobile. Background technique [0002] With the rapid development of my country's automobile industry, the number of automobiles continues to increase. While automobiles bring convenience, people are paying more and more attention to power, economy, driving comfort and handling. Continuously variable transmissions are recognized by more and more consumers for their good smoothness, fuel economy and driving comfort. See figure 1 , figure 1 It is a structural schematic diagram of a continuously variable transmission in the prior art. In an automobile equipped with a continuously variable transmission, after the power is output from the engine 10, it passes through the torque converter 11, the forward and reverse clutch (Drive Reverse, DR) 12 and the planetary row. 13. The pulley s...
