  • Patent number: 6701671
    Abstract: A vehicular slide door apparatus includes a movable slide door, inside and outside door handles operable to initiate opening and closing movement of the door, a drive device that assists the slide door movement, and a remote control device that includes a door lock device and a switch. An open lever is operatively associated with the inside door handle to transmit operation of the inside door handle to the lock device, and a child-proof lever is operable to prevent operation of the inside door handle from being transmitted to the open lever. The switch is engageable by the open lever and is operatively associated with the drive device such that operation of the inside door handle produces selective actuation and non-actuation of the switch depending upon the position of the child-proof lever, with the actuation of the switch effecting driving operation of the drive device.

  • Patent number: 6580243
    Abstract: A door speed is detected at every predetermined detecting time, and a door position is calculated at a timing detected the door speed. A target speed according to the door position is obtained by a map. A microcomputer calculates a speed difference &Dgr;VD between the target speed and the actual or present speed, and an acceleration/deceleration value &Dgr;VC such as the speed difference between the door speed at the last detecting time and the present detecting time. A duty increasing value and the decreasing value of a PWM duty command value for adjusting a torque of the motor are set based on the speed difference &Dgr;VD and the acceleration/deceleration value &Dgr;VC, the motor is driven by the PWM duty command value based on the duty increasing value and the decreasing value.

  • Patent number: 6510656
    Abstract: A door closing apparatus that is adapted to be disposed on a vehicle door having a door inner panel and an indoor trim includes a door lock mechanism having a latch, a pawl and a latch lever fixedly secured to a rotary shaft of the latch, a bracket adapted to be supported in a fixed relationship with respect to the door panel, and a passive lever rotatably supported by the bracket and provided with a free end portion adapted to contact the latch lever, and a drive source which rotates the passive lever. A shaft portion rotatably supports the passive lever with respect to the bracket, and a nut threadedly engages the shaft portion and is removable from the shaft portion, with the nut being positioned at a side of the bracket facing the indoor trim. In the event the latch lever is unable to rotate (e.g., due to disconnection of an electrical wire or motor malfunction), the indoor trim of the vehicle door can be partially peeled off and the nut removed to manually move the passive lever.

  • Patent number: 6408573
    Abstract: A vehicular slide door apparatus includes a slide door which is movable between an open position and a closed position, and a drive device having a shaft which couples the slide door and an electric motor. When the motor is turned on, the slide door moves. The shaft is provided with a magnetic member which is sensed while the shaft is rotating by a sensor having a Hall element. This allows a direct determination of the shaft rotation so that such determination and successive determinations of the slide door movement become as accurate and precise as possible.

  • Patent number: 6405485
    Abstract: A door control device is adapted to smoothly shift the mode of operation to the door closer operation at the time the door is being moved by pushing in the door closing condition, without requiring a large size motor and without the need for increasing the strength of the drive medium. The door control device includes a closer for shifting a slide door from the half door condition to the fully closed condition, and a clutch mechanism which is interposed in a power transmission system between the slide door and a motor for driving the slide door. If the slide door is electrically driven, a clutch of the clutch mechanism is rendered operational to move the slide door and the closer operation is started after the sliding operation.
