Abstract
A vehicle control device includes: dual-system control circuits that control power supply to dual-system winding sets of a motor; and dual-system rotation detection circuits. The control circuits calculate an absolute rotation angle of the motor, and, when a power source is turned off, store an absolute rotation angle of the motor at that time. The control circuits start when the power source is turned on and the absolute value of a difference between an absolute rotation angle that was stored when the power source was turned off last time and an absolute rotation angle that is calculated when the power source is turned on this time is equal to or smaller than a given threshold value, regardless of whether an abnormality has occurred in one of the dual-system rotation detection circuits or an abnormality of the dual-system rotation detection circuits is not determinable.
