Abstract: A drive system, in particular for an electric and/or hybrid vehicle, including a static part (S) and a rotatably mounted part (D) and also an electric motor with a stator (1) and rotor (2), wherein the static part (S) includes the stator (1) and the rotatably mounted part (D) includes the rotor (2). To identify a tilt of the bearing or of the rotor, in particular in order to prevent abrasion of the rotor (2) against the stator (1) and/or to identify damage in the system, the drive system includes a bearing tilt detection system for detecting a bearing tilt of the rotatably mounted part (D), wherein the bearing tilt detection system evaluates data of the electric motor and/or of at least one sensor (10, 20, 30) with regard to whether a bearing tilt is present. The invention also relates to an electric and/or hybrid vehicle.
