A powered vehicle door closing system for producing an auto-closing action to automatically move a latch member from a half-latched position to a fully-latched position comprises a reversible motor mechanically linked through a linkage to the latch member, for powering a final, low-displacement/high-force movement of a vehicle door, and a controller for controlling the motor. The controller includes a full-latch confirmation section for confirming that the latch member is maintained at its fully-latched position, and a motor-drive limiting section for limiting re-activation of the motor so as to avoid ineffective auto-closing action of the system when the full-latch confirmation section decides that the latch member has already been shifted to and maintained at the fully-latched position.

A temporarily holding device for temporarily holding an opening/closing body such as a sliding door for a vehicle in such a manner as to allow it to be moved from a halted state with a required operating force, comprising, in order not to fluctuate the moving resistance remarkably in any condition by providing the moving resistance of a required limit in the form of electrical control while the opening/closing body is being halted, an opening/closing body movably supported on a guiding mechanism, a motor-driven clutch for freely connecting and/or disconnecting the guide mechanism to and/or from an opening/closing body holding mechanism and a clutch driving element for regulating the transmission maintaining force of the motor-driven clutch, wherein the clutch driving element is designed to set the transmission maintaining force of the motor-driven clutch when the opening/closing body is halted with a required opening smaller than when it is in motion.

An automotive electric door lock system comprises a door lock which includes a latch plate latchedly engageable with a striker secured to the vehicle and a locking plate which is pivotable between an engaging position wherein the locking plate engages the latch plate and a releasing position wherein the locking plate releases the latch plate. An electric actuator is employed for moving the locking plate from the engaging position to the releasing position when energized. A power supply device energizes the electric actuator when a door handle is manipulated. A control device is used for instantly stopping the electric power supply to the electric actuator when the locking plate arrives at the releasing position.

A drive control device for an opening/closing member may be advantageously utilized in vehicular power window systems and the like. The drive control device is active to detect occurrence of pinching of an object obstructing the path of motion of the opening/closing member and, upon detection of such pinching during closing operation is controlled so as to move in the opening direction for a predetermined distance for preventing serious pinching from being applied to, for example, a persons hand or arm which may be blocking a power window while being closed by a vehicle driver. The drive control device further includes timing functions such that closing operation may not be immediately resumed after pinch detection, until a predetermined time period has elapsed. The pinch detection operation is effective to compensate for overrun of the opening/closing member caused by a lag between the time a closing control signal is stopped and the acutal motion of the opening/closing member finally and completely stops.

A control device controls an open/close movement of an automotive window pane which is driven by an electric motor. The device comprises a first switch for, when taking ON position, energizing the motor to drive the closure in a first direction toward a pull-opened position and a second switch for, when taking ON position, energizing the motor to drive the closure in a second direction toward a full-closed position. A determining device is provided for determining an energization stopping position which is taken by the closure before taking the full-opened position when moved in the first direction. The energization stopping position and said full-opened position are separated by a given distance. A controller is further provided which stops energization of the motor when the closure comes to the energization stopping position during movement in the first direction. The given distance is a distance for which the closure can run by the force of inertia produced when energization of the motor is stopped upon reaching of the closure to the energization stopping position during movement in the first direction.

The controller comprises a full-latch detection section for detecting the fully-latched position of the latch member and a stand-by position detection section for detecting the stand-by position of the linkage. To detect the fully-latched position and the stand-by position, the full-latch detection section and the stand-by position detection section respectively utilize changes in load imparted to the motor.
摘要:
A drive control device for an opening and closing member is active to optimally adjust a threshold level for pinch detection. Utilizing a speed sensor or the like, the closing speed of the opening/closing member is detected. The value of the closing speed is renewed in accordance with the closing position and stored in memory. Based on memorized data, a predicting circuit derives a future closing speed. To the predicted value there is added an allowed addition value, to permit a threshold level setting circuit to set an appropriate threshold for pinch detection. The allowed addition value is adjusted in accordance with the closing speed of the opening/closing member by a threshold level adjusting circuit.
