Abstract
A method for actuating the transmission of a motor vehicle having a hybrid drive mechanism, especially for the case when an electric accumulator is loaded via the internal combustion engine and the selector lever () is locked electronically or via a mechanical selector lever locking device during the loading operation. Regarding the selector lever actuation, the driver's wish is detected by way of a sensor device () and when it is determined that the drive is going to activate a running step by the sensor device (), the loading operation of the electric accumulator is immediately discontinued, via the internal combustion engine, and an operating state is adjusted which allows a safe activation of a transmission running step and subsequently the lock of the selector lever () is released or the selector lever locking device () is unlocked.
