Patent ID: 8521375

Claim:
A transmission control device of a transmission for a drivetrain in combination with a hybrid drive comprising; an internal combustion engine ( 1 ), only a single electric motor ( 2 ) and the transmission ( 3 ), an output of the internal combustion engine ( 1 ) being connected, via a first clutch ( 5 ), with an input of the electric motor ( 2 ) and an output of the electric motor ( 2 ) being connected, via a second clutch ( 6 ), with the transmission ( 3 ), a plurality of parameters being stored in the transmission control device on a basis of which gearshifts are one of controlled and regulated, and at least some of the parameters are stored in duplicate, at least a first parameter, of the at least some of the parameters stored in duplicate, being a parameter which forms a basis for operation of the transmission ( 3 ) only when driving purely under electric-motor power using only the electric motor ( 2 ) with only the second clutch being engaged so as to enable gearshifts during purely electric motor driving using the at least first parameter, and the at least first parameter comprising at least one mass moment of inertia of the drivetrain parameter, which excludes a mass moment of inertia of the internal combustion engine ( 1 ), for controlling gear shifts during purely electric motor driving, and at least a second parameter, of the at least some of the parameters stored in duplicate only forming a basis for operation of the transmission ( 3 ) during hybrid driving using both the internal combustion engine ( 1 ) and the electric motor ( 2 ) with both the first and second clutches being engaged so as to enable gearshifts during hybrid driving using the at least second parameter, and the at least second parameter comprising a mass moment of inertia of the drivetrain parameter which includes the mass moment of inertia of the internal combustion engine ( 1 ), for controlling gear shifts during hybrid driving.
