Abstract

The invention provides an off-axis type second-speed transmission control system, which includes a controller connected to the off-axis second-speed transmission. The off-axis second-speed transmission includes an input shaft, an output shaft, an intermediate shaft, a switching Dual clutch, housing, oil circuit structure and oil circuit control system; the controller includes an analog output unit connected to the control unit; the controller is used to obtain the gear information, according to the pre-stored gear The corresponding relationship between the bit information and the control of the analog output unit is used to 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 an off-axis type second-speed transmission control system. Background technique [0002] The off-axis second-speed 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 shift control system of an off-axis type second-speed transmission to solve the problem that the existing transmission needs to be automatically and quickly sh...
