<P>PROBLEM TO BE SOLVED: To accurately estimate the torque of each induction motor even if there is dispersion in diameters of wheels in the case of driving a plurality of wheels with a plurality of induction motors. <P>SOLUTION: This controller gets the first torque of each of the above induction motors, based on the rotational speed and the output voltage of individual induction motors by a first torque operating part 13, and calculates the second torque of each of the above induction motors from the first torque and a torque command, and transmits the second torque estimated by the second torque operating part 14 to a cabin display by a communication part 16 so as to display it. The cabin display detects the dispersion of the diameters of wheels being over the tolerance from the second torque estimate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
