Problems solved by technology

[0002] The integrated control module of the existing dual-clutch automatic transmission is mainly the control module of the integrated hydraulic valve, including oil passages and various control valves, and the shift mechanism, that is, the piston cylinder, is generally arranged on the gearbox housing to detect the position of the synchronizer displacement The sensor is also arranged on the gearbox housing. This design makes the processing and assembly process extremely complicated, and the degree of integration is not high. In addition, in order to accurately control the entire gearbox, it is necessary to adopt a feedback control method, that is, in the hydraulic pressure The pressure sensor is used in the system. For example, the dual clutch will produce a continuous friction process during the process of coupling and separation. The control of the friction process is the core content of clutch control. Different clutch coupling and separation time periods, the clutch needs The pressure of the clutch is also different. In order to keep the clutch in the best working condition, it is necessary to precisely control the pressure of the clutch. The traditional design is to install the pressure sensor on the oil passage of the gearbox case. This design leads to the design of the gearbox case. The manufacturing is complicated, and the gearbox is too bulky to be used in miniature cars
