Abstract

The invention provides a speed change control system of a four-speed transmission, the controller is connected with the four-speed transmission, and the four-speed transmission includes an input shaft, an output shaft, an intermediate shaft, a first switching double clutch, a second switching double clutch, a housing body, oil circuit structure and oil circuit control system; the controller includes a plurality of analog output units, and the plurality of analog output units are respectively connected with the first control unit and the second control unit; the controller is used for The gear information is obtained, and the analog output unit is controlled to output different analog control information to the first control unit and the second control unit according to the control correspondence between the pre-stored gear information and the analog output unit. The present invention realizes the purpose of automatic and fast shifting through the controller.

Description

technical field [0001] The invention relates to the field of transmission control systems, in particular to a four-speed transmission control system. Background technique [0002] The four-speed transmission can realize the change of four gears, and through different gear changes, different torques input from the front and rear can be changed. Through the switching of different clutches of the transmission, the switching of different gears of the transmission can be realized. Existing manual gear shifting can be realized by manually opening and closing proportional valves of different clutches. In order to realize fast and automatic transmission gear switching, a transmission gear control system is required. Contents of the invention [0003] For this reason, it is necessary to provide a speed change control system for a four-speed transmission to solve the problem that the existing transmission needs to be automatically and quickly shifted. [0004] In order to achieve...
