Abstract
A transmission control device () of a transmission () for a drivetrain which includes, in addition to the transmission (), a hybrid drive with an internal combustion engine () and an electric motor (). The transmission control device () stores parameters which form the basis of the manner with which gearshifts are controlled or regulated. At least some parameters are stored in duplicate, firstly, for operating the transmission () under purely electric-motor power using only the electric motor (), and secondly for operating the transmission () during hybrid driving using both the internal combustion engine () and the electric motor ().
