Abstract
A steering apparatus includes: a mechanism that turns a turning wheel; a first motor that generates a driving force that is given to the mechanism; and a control device. The control device includes: a first computation circuit that computes a first limiting value to which an electric current to be supplied to the first motor is limited in a particular situation; a determination circuit that determines whether the turning wheel is in touch with an obstacle; a second computation circuit that computes a second limiting value to which the electric current to be supplied to the first motor is limited when the determination circuit determines that the turning wheel is in touch with the obstacle; and a third computation circuit that computes the threshold to be used by the determination circuit, based on a smaller limiting value of the first limiting value and the second limiting value.
