Abstract

A system and method for controlling a hybrid vehicle drive has a device for detecting a charging power of a heavy-duty battery for an electric motor, a device for determining at least one fuel consumption parameter for several different transmission gear positions at the detected charging power and for determining an optimized gear position in which the determined fuel consumption parameter indicates an optimized fuel consumption. The determining device controls the gear position of the transmission to the determined optimized gear position by via a transmission control device.
