20120323370 | OPENING-AND-CLOSING MEMBER CONTROL DEVICE - An opening-and-closing member control device for controlling a driving device to operate an opening-and-closing member according to a target speed includes a detection portion detecting an operational state of the driving device during the control, a disturbance determination portion for determining whether a disturbance is generated at the opening-and-closing member, which is applied in the same direction to an operating direction of the opening-and-closing member during an opening-closing operation of the opening-and-closing member, by monitoring at least one of a change in an electric signal and in an operation speed of the opening-and-closing member generated relative to the target speed, and a threshold value changing portion for switching an entrapment threshold value when the disturbance determination portion determines that the disturbance is generated. Whether an external object is entrapped at the opening-and-closing member is detectable by comparing an electric signal obtained by the detection portion and the entrapment threshold value. | 12-20-2012 |
20140245666 | DOOR-OPENING/CLOSING DEVICE FOR USE IN VEHICLE - A door opening/closing device for use in a vehicle is provided with a driving member. The driving member has a permanent-magnet motor provided with two terminals and an output member, which is rotationally driven by the permanent-magnet motor. The driving member is mounted on either a vehicle body or a vehicle door and is coupled to the other via the output member. As the output member rotates, the vehicle door opens or closes. The door opening/closing device is also provided with a switching device configured to switch the permanent-magnet motor between an energizable state, in which the permanent-magnet motor can receive electricity through the two terminals, and a brake state, in which the terminals are short-circuited. The switching device switches the permanent-magnet motor into the brake state when the vehicle door is in any position other than the fully closed position. | 09-04-2014 |
20140365080 | DEVICE FOR CONTROLLING OPENING/CLOSING BODY FOR VEHICLE - An opening/closing body control device for a vehicle includes: a drive section for driving the opening/closing body; a manipulation input section operated to open or close the opening/closing body; a manipulation input detector for detecting a manipulation input performed on the manipulation input section; a controller for controlling the drive section; and a measuring section for measuring a duration of the manipulation input. The controller is capable of controlling the drive section in the driving mode selected from a plurality of driving modes to which are set different speeds of actuation of the opening/closing body, and to switch, if the duration exceeds a predetermined time, the driving mode to a high speed actuation mode in which the actuation speed is greater than that in the driving mode before the predetermined time is exceeded. | 12-11-2014 |
20150020450 | VEHICLE DOOR OPENING/CLOSING DEVICE - A vehicle door opening/closing device, which enhances the operation feeling during opening and closing of a vehicle door, includes: an outside door handle provided to a power sliding door for opening and closing a door opening, the outside door handle being supported to move between an initial position and a maximum movement position relative to the power sliding door, and being operated to open and close the power sliding door; a spring unit urging the outside door handle to move from the maximum movement position to the initial position; an opening/closing operation detection unit for detecting movement of the outside door handle from the maximum movement position to the initial position; a door drive mechanism for driving the opening and closing of the power sliding door; and a control unit for actuating the door drive mechanism on the basis of a detection signal outputted from the opening/closing operation detection unit. | 01-22-2015 |
20150057895 | DEVICE FOR CONTROLLING VEHICLE OPENING/CLOSING ELEMENT - An opening/closing body control device for a vehicle is provided with a drive section configured to drive an opening/closing body of a vehicle, and a controller configured to control the drive section. In response to detection of an external force input intended to accelerate the opening/closing body in operation, the controller controls the drive section to increase the operating speed of the opening/closing element. The drive section determines that the external force intended to accelerate the opening/closing body has been input if, as one example, the acceleration of the opening/closing body in an operation direction reaches a predetermined value or higher. | 02-26-2015 |
