Abstract
A flexible drive concept for a vehicle is provided. As a result, the claimed drive device includes a shifting device which can shift a transmission gear and an intermediate gear into different shifting states such that a second motor can be selectively used in two gears as a drive motor or alternatively as a torque vectoring motor.

16. A drive device for a vehicle, comprising:
-
a first and a second output shaft; a first interface for coupling a first engine; a differential device for distributing the drive torque from the first interface to the first and second output shafts, the differential device including an input and two outputs, the input of the differential device being coupled to the first interface, the two outputs of the differential device being coupled to the first and the second output shafts; a second interface for coupling a second engine; a transmission for transmitting the drive torque of the second engine or of the second interface, the transmission including a transmission input and two transmission outputs and the transmission input of the transmission being coupled to the second interface; an intermediate gear, the intermediate gear being situated between the transmission and the differential device; and a shifter, the shifter being designed to couple the transmission and the intermediate gear to one another in at least two different shifting states;
the intermediate gear including a first and a second input, in a first shifting state of the shifter the first transmission output of the transmission being rotatably fixedly connected to the first input of the intermediate gear so that drive torque is distributed to the first and second output shafts from the second interface via the differential device;in a second shifting state of the shifter, the second transmission output of the transmission being rotatably fixedly connected to the first input of the intermediate gear so that the drive torque is distributed to the first and second output shafts from the second interface via the differential device; and in a third shifting state of the shifter, the first or the second transmission output of the transmission is rotatably fixedly connected to the second input of the intermediate gear so that the drive torque of the second interface is usable for a drive torque distribution. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
