Device for determining a torque in a drivetrain of an at least partially electrically operated motor vehicle

A device for determining a torque in a drivetrain of an at least partially electrically operated motor vehicle, the device comprising:

• a first electric motor having a first rotor, the first rotor being directly mounted in at least first and second rolling bearings that are mutually spaced in an axial direction of the first rotor, and the first rotor of the first electric motor is connected to a first vehicle wheel so that the first electric motor drives the first vehicle wheel;
• the first rolling bearing has a first angular position sensor;
• the second rolling bearing has a second angular position sensor, wherein the first rolling bearing is arranged inside the first electric motor and the second rolling bearing is arranged outside the first electric motor and in or on a vehicle wheel;
• and
• each of the first and second angular position sensors generate a signal representing an angular position of the first rotor at a respective bearing point, and the signals representing the angular positions are transmitted to a vehicle controller that is configured to determine the torque of the first electric motor which is applied to the first rotor from a difference in the angular positions and the torque is provided for controlling the motor vehicle.
