Abstract
A control device includes: a deceleration control unit that performs a free running deceleration control that controls free running deceleration when transition occurs from an operation state to a non-operation state; an index deriving unit that derives a transition phase perceptual risk index; and a relationship adjusting unit that adjusts a relationship between a perceptual risk index and a deceleration. The deceleration control unit derives the deceleration corresponding to the transition phase perceptual risk index based on the relationship and sets the derived deceleration as the free running deceleration. The relationship adjusting unit executes a correction control in which when the transition phase perceptual risk index is larger than the reference perceptual risk index, the reference perceptual risk index is corrected to be increased, and when the transition phase perceptual risk index is smaller than the reference perceptual risk index, the reference perceptual risk index is corrected to be decreased.
