A drivetrain system can drive a vehicle by a first motor and a second motor. A drivetrain couples the first motor with a first axle and comprises a propeller shaft transmitting torque from the first motor to a second axle and coupled with the second motor. A first clutch disconnectably connects the first motor with the propeller shaft. A second clutch disconnectably couples the propeller shaft with the second axle. The first and second motors can be activated. The first clutch can be connected to cause both the first and second motors to drive the first axle. The second clutch can be connected or disconnected to control torque transmission from the first motor and the second motor to the second axle, whereby the vehicle is operated in a hybrid mode in which both the first motor and the second motor drive the vehicle.
A method for controlling a drivetrain to drive a vehicle by a first motor and a second motor, the drivetrain uninterruptedly coupling the first motor with a first axle and comprising a propeller shaft transmitting torque from the first motor to a second axle and being uninterruptedly coupled with the second motor, a first clutch for disconnectably connecting the first motor with the propeller shaft, and a second clutch for disconnectably coupling the propeller shaft with the second axle, the method comprising:
