ABSTRACT:
An ECU executes a program including the steps of detecting a temperature TB of each battery block, calculating a desired output value VT of each motor based on a detected temperature, detecting output value V of each motor based on a signal transmitted from an F/V conversion circuit converting a pulse signal of a speed sensor provided on each motor into a voltage, reading a last DUTY command value D, calculating a difference DV between desired output value VT and output value V (DV=VT−V), calculating a DUTY command correction value for each motor based on difference DV, and adding a calculated DUTY command correction value to last DUTY command value D to calculate DUTY command value D.
