PROBLEM TO BE SOLVED: To assist determination of the switched state of an electric switch machine based on a measurement result.;SOLUTION: A stroke period for switching operation of an operating rod is estimated based on motor current I measured during the switching operation of the electric switch machine. Then, as state index values of the switching operation, average values and maximum values of motor voltage V and motor current and an average value and a maximum value of load torque T during the stroke period are calculated.;COPYRIGHT: (C)2012,JPO&INPIT
