Abstract
Torque restrictions on a drive shaft are enhanced when the angular acceleration AX of the drive shaft exceed a specific first threshold value. The enhanced torque restrictions are subsequently relaxed when the angular acceleration drops below the first threshold value and further a specific restriction relaxation condition is satisfied. The torque restrictions are expressed as a graph representing a relation according to which an upper torque limit Tmax decreases with increased angular acceleration AX. The torque restriction are enhanced or relaxed by moving the position of a torque axis relative to the graph along the angular acceleration axis while preserving a shape of the graph.
