  • Patent number: 10597259
    Abstract: A side of the seal member 35 is provided rotatably to a car-side door sill 31. The rotation of the side allows the side to be displaceable between a sealing position and an evacuation position. The link mechanism for rotating the seal member 35 releases an engagement with the car-side actuating member to rotate the seal member 35 to a sealing position and fixes the seal member 35 at the sealing position. The link mechanism engages with the actuating member and releases the fixing of the seal member 35 at a sealing position when the car door moves to the door-close end.

  • Patent number: 10479352
    Abstract: A method and an apparatus for controlling an engine clutch are provided. The method includes determining whether an engine start condition is satisfied when an engine is stopped and performing an engine cranking operation by operating a hybrid starter & generator (HSG) when the engine start condition is satisfied. Whether an engine speed is greater than or equal to a first reference speed is determined to thus reduce an HSG torque. Then, whether the engine speed is greater than or equal to a second reference speed is determined to thus calculate a target speed of the engine. A speed control of the engine is performed using the target speed of the engine while determining whether an engine clutch engagement condition is satisfied. An engine clutch is engaged when the engine clutch engagement condition is satisfied.
