Abstract
The method for monitoring the wear of a powertrain includes an analysis cycle that includes, in this order, preventing mechanical components from moving; rotating an electric motor in a first direction until a torque value delivered by the electric motor reaches a predetermined threshold, a first angular position of the electric motor being reached; rotating the electric motor in a second direction opposite to the first direction until a torque value delivered by the electric motor reaches the predetermined threshold, a second angular position of the electric motor being reached; and calculating a backlash value of the powertrain on the basis of the first and second angular positions. The method further includes comparing the backlash value calculated during the analysis cycle to a reference value to monitor wear of the powertrain.
