    Abstract: An apparatus to facilitate vehicle door closing includes a rack gear engaging a pinion gear that are connected between the door and a hinge pillar. A spring is operatively connected to the pinion gear stores energy during a portion of a door opening motion and releases the stored energy to bias the door to close. A damper operatively connects the spring and the door to limit the door closing speed during a portion of the door closing motion. A power cinching mechanism may be operatively coupled to the door closing apparatus to assist in the final closing motion of the door.

    Abstract: A hinge apparatus generally includes a hinge pin formed of a two-way shape memory alloy (SMA) adapted to transition, without an externally applied load, between a first trained shape and a second trained shape upon switching the two-way SMA between a first state and a second state. The hinge pin can apply two-way reversible actuation forces to a device coupled to the hinge apparatus. The hinge pin can be produced by thermal cycling a material under a sufficient load for a sufficient number of thermal cycles between about the material's austenite and martensite temperatures to complete training of the material. The thermal cycling conditions the material to transition, without an externally applied load, between an austenitic shape and a martensitic shape to perform useful work when the material is thermally cycled between the austenite and martensite temperatures.

    Abstract: A method for controlling a sliding door system determines the masses and the frictional forces of all movably interconnected parts of the sliding door system. The system has a door leaf which is moved in an opening learning travel and a closing learning travel and guided without drive over respective first and second test sections. First and second energy balances are determined from the detected speed and distance travelled data of the first and second test sections respectively. The energy balances equate the kinetic energy at the beginning of a test section with the kinetic energy at the end of the test section plus the frictional energy plus the potential energy of a closing weight connected to the door leaf. The potential energy is added with a positive sign for opening travel and a negative sign for closing travel. The dynamic mass and the mean frictional force of the sliding door system can then be determined from the first and second energy balances. An apparatus for controlling the door motor in accordance with the method includes a microprocessor in a door drive with a memory for storing the speeds and distances associated with the learning travels. The microprocessor and the tachometer detect, store and process the speed and distance data, and the microprocessor determines the values for the dynamic mass and the mean frictional force and also the closing speed, which is the maximum permissible for safe operation of the door.
