Description

The control method of transmission device

Technical field

The present invention relates to vehicle drive system fields, and more specifically, are related to one kind in engine and fluid drive The transmission device of torque, and the control method for the transmission device are transmitted between device.

Background technique

It is equipped with transmission device it is known that vehicle is standing the torque exported from engine is transmitted to speed changer.For For automatic transmission, frequently with fluid torque-converter as the transmission device.The principle of fluid torque-converter is by the wheel blade that works Interaction between piece causes the energy between mechanical energy and liquid energy to be converted.

However, unexpected energy loss can often occur for the transition period for transmitting energy in fluid torque-converter work.Example Such as, since the oil of transmission generates diriven motion, cause a part of kinetic energy to be converted to kinetic energy, increase and influence so as to cause oil temperature The efficiency and fuel economy of such fluid torque-converter.

It is therefore desired to design a kind of new transmission designs and its control method, can at least reduce certainly Transmission loss in dynamic transmission torque transmission.

Summary of the invention
