Abstract
Provided is a vehicle door opening/closing device. Given that a door is in an initial fully-open position, a storage unit stores: a target speed map for defining a relation between the door position and the target speed of a motor; and information indicative of an arbitrary fully open position set by a user. A map speed computation unit calculates a map speed based on the target speed map, whereas a gradually decreasing speed calculation unit calculates a gradually decreasing target speed for decreasing at a prescribed deceleration rate as the arbitrary fully open position gets closer so that a prescribed terminal speed is reached at the arbitrary fully open position. A speed sequence control unit switches a set target speed to the gradually decreasing target speed from the map speed at a door position where the gradually decreasing target speed becomes slower than the map speed.
