  • the present invention has the advantage that no additional sensors at the driving assembly are needed and the torque at the driving wheel or a value dependent on the torque at the driving wheel can be easily determined.
  • the control device correlates a determined torque at the driving wheel or the value dependent on the torque at the driving wheel to the first or second crank dependent on the position of the first and second crank.
