Abstract:
A vehicle includes a body and front and rear doors having front and rear powered latches, front and rear anti-pinch sensors, and front and rear electrically-powered door openers. The vehicle further includes a controller that is configured to receive an unlatch signal from unlatch sensors/switches and generate a signal to unlatch the front and rear powered latches and actuate the front and rear door openers after the front and rear powered latches are unlatched. The controller may also be configured to actuate the rear door opener to retain the rear door in an open position when the front pinch sensor detects a hand to thereby prevent pinching.
Abstract:
An electric operator for a sliding door mounted for sliding movement along a track, comprising a motor having an iron cooling flywheel disposed on a drive shaft thereof, the flywheel being provided for imparting a predetermined amount of inertia for starting and stopping of the motor such that the operation of the motor is characterized by a soft start and stop. A worm gear reducer is connected to the drive shaft for effecting a predetermined reduction ratio of rotation. A limit switch is coupled to the reducer for limiting rotation of the drive shaft to a predetermined number of rotations, and apparatus is provided for coupling rotation of the drive shaft to the linear movement of the sliding door along the track.
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:
The invention relates to a hatch actuation unit of a motor vehicle for a drive based opening and closing of a hatch leaf comprising a hatch drive arrangement for moving the hatch leaf in an opening sequence from a closed hatch position into an open hatch position and in a closing sequence from an open hatch position into a closed hatch position, a first closing element for engaging a second closing element for closing of the hatch leaf in a cinching subsequence of the closing sequence, wherein the first closing element is driven by the hatch drive arrangement in the cinching subsequence of the closing sequence.
Abstract:
Mit diesem Verfahren werden bei einem Schiebetürsystem (1) die Massen und die Reibkräfte aller beweglich miteinander verbundenen Anlageteile auf den Türflügel (2) bezogen und mit Hilfe des Schliessgewichtes (G) numerisch bestimmt. Hierzu wird der Türflügel (2) einer Öffnungslernfahrt (ÖL) und einer Schliesslernfahrt (SL) unterzogen und dabei, nicht-angetrieben, über je eine Teststrecke TS1 bzw. TS2 geführt und aus dabei gemessenen kinematischen Parametern (v1,v2,s1) bzw, (v3,v4,s2) je eine erste Energiebilanz (EB1) bzw. eine zweite Energiebilanz (EB2) aufgestellt. Die Energiebilanzen (EB1, EB2) enthalten die potentielle Energie (Ep) des Schliessgewichtes (G) mit positivem bzw. negativem Vorzeichen und ergeben in Kombination spezielle Formeln für die numerischen Werte der dynamischen Masse (md) und der mittleren Reibkraft (Fr*) des Schiebetürsystems (1). Zum Messen, Speichern und Verarbeiten der kinematischen Parameter sowie zum Berechnen der numerischen Werte der dynamischen Masse (md) und der mittleren Reibkraft (Fr*) dienen der Mikroprozessor (3,1) und der Inkrementalgeber (3.2) des Türantriebes (3). Das Verfahren ist allgemein auf Massesysteme und deren physikalische Kennwerte anwendbar und eignet sich insbesondere zur Bestimmung der sicherheitstechnisch maximal zulässigen Schliessgeschwindigkeit (vsmax) von Schiebe- und Schwenktüren.
