Title:
VEHICLE DOOR OPENING/CLOSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/234981
Kind Code:
A1
Abstract:
Provided is a vehicle door opening/closing device with which it is possible to suppress vibration of a door during automatic opening control. Given that a door is in an initial fully-open position, a storage unit MEM retains: a target speed map 66 for defining a relation between the door position and the target speed of a motor; and information (67) indicative of an optional fully-open position set by a user. A map speed computation unit 75 computes a map speed ω*m on the basis of the target speed map 66, whereas a gradual deceleration computation unit 77 computes a gradual deceleration target speed ω*d for decelerating at a prescribed deceleration rate as the optional fully-open position gets closer so that a prescribed end speed ω*ed is reached at the optional fully-open position. A speed sequence control unit 65 switches a set target speed ω*t to the gradual deceleration target speed ω*d from the map speed ω*m at a door position where the gradual deceleration target speed ω*d becomes slower than the map speed ω*m.
