Abstract
A hybrid drive device for a motor vehicle with an internal combustion engine includes a first electric motor and a second electric motor. A transmission includes a first partial transmission connected to the first electric motor and a second partial transmission connected to the second electric motor, each being connectable to an output shaft. The internal combustion engine can selectively be uncoupled from the transmission or can be connected in a form-fit manner to the first or the second partial transmission. The first electric motor is connected at a constant gear ratio to a first drive shaft of the first partial transmission, and the second electric motor is connected at a constant gear ratio to a second drive shaft of the second partial transmission. The internal combustion engine can also be connected in a form-fit manner to the output shaft by way of a direct gear-change means.
