How to solve the DCT transmission low-speed problem?

Double clutch transmission in the low speed prone to frustration, the coilovers main reason is the dual clutch transmission without hydraulic torque converter, but rely on friction directly to the torque transmission to the drive shaft, although there is no hydraulic torque converter to bring the power loss, But the friction plate is not the role of hydraulic torque converter buffer, the two sets of clutch plate in the shift operation, easy to produce a sense of impact.
Similar to the manual gearbox, there are similar semi-linked states in the power transmission process of the dual-clutch gearbox, in order to reduce the wear of the clutch plate. So TCU software engineers will let the clutch plate and friction plate as soon as possible, this time if the engine output speed and transmission output speed difference is relatively large, there will be frustration.
One solution is to optimize the hydraulic control unit, through the hydraulic cylinder to push the clutch plate to friction, reduce vibration, thereby reducing the generation of frustration. Volkswagen code DQ200 7-speed dry dual-clutch gearbox using mechanical control arm and sleeve Turbo for sale squeeze diaphragm spring deformation, from the structure point of view of its transmission efficiency is higher, optimized for the hydraulic system to promote, to better filter vibration, Thus further reducing the generation of frustration.
Software control, you can optimize the dual-clutch transmission of the shift logic, through the actual shift data to determine the correction of bias, can help double-clutch transmission torque and separation of the control position more accurate, low speed ride in the use of the process Gradually improved.
In addition to the above mentioned gearbox optimization, the vehicle ride comfort is also related to the engine. The torque response speed of the engine is also one of the factors that affect the driving experience.
At the same time, the powertrain mounting design also has a certain impact on the driver's perceived ride comfort.
