Coupling control, especially for converter coupling in automatic gearbox, involves using modified turbine revolution rate as input parameter on driven side outside switching process

摘要

The method involves regulating a driven and drive side revolution rate difference with engine and turbine revolution rates as input parameters. A modified turbine revolution rate used as the driven side input parameter outside a switching process, is derived by interpolation or extrapolation between the turbine revolution rate and a wheel revolution rate, depending on a factor that can be variably placed in a separate characteristic field.
