Description

technical field

[0001] The invention relates to the field of planetary gear transmissions, in particular to a shifting fluid control device for a one-control two-speed transmission and a working method thereof. Background technique

[0002] At present, no matter in the field of traditional automobile or new energy automobile transmission, the circuits and software that control the shifting of the transmission are usually complicated, and one or more pressure sensors, speed sensors, proportional valves or quick on-off valves need to be configured. The cost is high and the space is large. At the same time, the control of the shifting process is complicated and the shifting time is long. The relevant signals are at risk of being interfered. Even problems such as transmission damage will not only affect the driving comfort, but also affect the service life of the transmission. With the development of new energy vehicles, the one-control two-link interlock shifting mechanism is ...
