Abstract
When one of two winding systems fails, an ECU transitions from a first state in which a target assist torque is produced using winding groups of the two winding systems to a second state in which using the remaining normal winding system. When the failed winding system has recovered to normal during an operation in the second state, the ECU carries out initial check that is inspection of the winding system recovered to normal prior to starting the power supply as follows. The ECU omits, from items of the initial check of the winding system recovered to normal, a specific item that is set as an item susceptible to an induced voltage generated in the winding group of the winding system recovered to normal as the motor is driven using the winding group of the normal winding system and carries out only the remainder items of the initial check.
