A control method for a frictional shift element of a motor vehicle transmission; an electronic control unit comprising the control method; as well as motor vehicle transmission operated with this control method

摘要

Enters the invention, a control method for a frictional shift element (23) of a motor vehicle transmission (20), in which the frictional shift element (23) for the transmission of torque can be acted upon with pressure hydraulically or pneumatically from the a, in an electronic control unit (26) implemented algorithm, with the use of current operating parameters of the motor vehicle transmission (20) and with the use of predefined parameters of the frictional shift element (23) is calculated. It is proposed that, in the case of the pressure calculation is used a factor which, as a function of the operational load of the frictional shift element (23) is predefined.Furthermore, the invention relates to an electronic control unit (20), in the processor (27) of this control method is implemented, as well as a motor vehicle transmission (20), which is operated with this control method.
