Abstract

The hybrid drive for a motor vehicle (10) has an internal combustion engine (400) driving an input shaft (120) by a coupling (320). A first electric machine (100) is permanently connected to the second input shaft (130) and a second electric machine (300) mounted on a flywheel (31) of the engine. The input shafts each have teeth (120a,130a) to engage corresponding teeth in an intermediate shaft coupled to the vehicle wheels via differential. An Independent claim is included for a control method for the vehicle drive.
