Abstract
A vehicle steering device includes: a steering mechanism that steers steered wheels by driving of a steering motor according to operation of an operation unit; a motor angle sensor that detects a rotation angle of the steering motor as an electrical angle; a steered angle sensor that detects a steered angle of the steered wheels; a storage unit in which correspondence between the electrical angle and the steered angle that are detected is stored in advance; and a failure determination unit that determines whether there is a failure or not by comparing the relation between the detected electrical angle and the detected steered angle with the correspondence between the electrical angle and the steered angle that is stored in the storage unit.
