Abstract

The invention provides a speed change control system for a second-speed transmission, which includes a controller connected to the second-speed transmission. The second-speed transmission includes an input shaft, an output shaft, an intermediate shaft, a switchable dual clutch, a housing, and an oil circuit structure and oil circuit control system; the controller includes an analog output unit, which is connected to the control unit; the controller is used to obtain the gear information, according to the pre-stored gear information and the control of the analog output unit Corresponding relationship, control the analog output unit to output different analog control information to the control 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 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...
