摘要

Method for the output-neutral load circuit of hybridized automatic transmissions with an arbitrary number of gear stages and a number n couplings and with a first of p drive units and at least one of p drive units based on a transformation of real transmission sizes of the hybridized automatic transmission into virtual sizes of a dual-clutch transmission with associated dual clutch transmission-specific base circuits comprising the following Steps: initiation of a shift operation for a gear change pairing (i, j) from a gear i with an actual gear ratio (γ) to a gear j with a target gear ratio (γ) as a function of a target gear specification, - acquisition of actual variables of the hybridized automatic transmission and the first and or the at least one further drive unit, wherein the actual variables comprise at least one of the following variables: o a drive shaft speed (ω) of at least one drive shaft of the hybridized automatic transmission o an output shaft rotational speed (ω) of an output shaft of the hybridized automatic transmission, o a drive torque (T) provided by the first and / or at least one further drive unit and applied to the at least one drive shaft of the hybridized automatic transmission, o currently set clutch capacities (T ) of the n clutches or a minimum and / or maximum available drive torque (T, T) of the first and / or the at least one further drive unit, - selecting at least one transformation factor as a function of at least one actual variable and the gear change pairing (i, j) from state tables Calculating at least one transformation equivalent for the calculation of at least one dual-clutch transmission-specific actuating quantity by the base circuit of the dual-clutch transmission as a function of at least one actual variable and / or the at least one transformation factor; calculating at least one dopp elec- tion gearbox-specific actuating quantity by a base circuit in dependence on at least one actual size and / or the at least one transformation factor and / or the at least one transformation equivalent, - calculating at least one automatic transmission-specific actuator quantity as a function of at least one actual variable and / or the at least one transformation factor and / or the at least one Transformation equivalency and / or the at least one dual clutch transmission-specific Stellquantitat and- implementing the at least one automatic transmission-specific Stellquantität by at least one actuator and the at least one further drive unit.
