The control of manpower cost in the whole society can effectively solve the problem of manual transmission's dependence on external manpower and environment. It can promote the development of civilian trucks for driving comfort, energy saving and emission reduction. With the improvement of road conditions and the development of the transportation industry, automatic transmissions provide strong support for the development of large-tonnage, high-power, multi-axis trucks.
Automatic transmissions also generally eliminate differences in truck fuel economy, power, emissions performance, and transmission system reliability caused by drivers of different levels. The automatic transmission is the foundation of the vehicle's hybrid power system. The hybrid power system must combine the vehicle's power system with the transmission system.
