Abstract

The invention provides a two-gear transmission speed change control system. The two-gear transmission speed change control system comprises a controller, wherein the controller is connected with a two-gear transmission; the two-gear transmission comprises an input shaft, an output shaft, an intermediate shaft, a switching type double clutch, a housing, an oil way structure and an oil way control system; the controller comprises an analog quantity output unit; the analog quantity output unit is connected with a regulation and control unit; and the controller is used for acquiring gear information, and controlling the analog quantity output unit to output different analog quantity control information to the regulation and control unit according to a control corresponding relation between pre-stored gear information and the analog quantity output unit. According to the two-gear transmission speed change control system, the purpose of automatic and rapid gear shifting is realized through the controller.

Description

technical field [0001] The invention relates to the field of transmission control systems, in particular to a transmission control system for a two-speed transmission. Background technique [0002] The second gear transmission can realize the change of two 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 two-speed transmission, which is used to solve the problem that the existing transmission needs to be automatically and quickly shifte...
