Abstract:
An anti-pinch assembly is used for a closure panel movable between open and closed positions on a motor vehicle. A controller operably connected to the closure panel controls operation thereof. A position sensor connected to the controller indicates the position of the closure panel between the open and closed positions. A capacitive sensor mounted on the vehicle and connected to the controller provides an output signal to the controller indicative of the presence of a foreign object in the path of the closure panel. The controller varies the function of the capacitive sensor through a plurality of threshold levels as a function of the position of the closure panel as indicated by the position indicator. In a critical zone of travel with the closure panel nearing the closed position, the capacitive sensor can be utilized in either a contact mode or a non-contact mode or a combination of both.

A latching assembly is used on a door of a motor vehicle, wherein the motor vehicle includes a main electric supply and a striker. The latching assembly includes a ratchet that is selectively rotatable with respect to the striker to latch and unlatch the door. The latching assembly includes a pawl that is selectively engagable with the ratchet to selectively prevent the ratchet from rotating. The latching assembly includes a motor which is electrically connected to the main electric power supply. The motor is operatively connected to the pawl for pivoting the pawl into and out of engagement with the ratchet. The latching assembly also includes a backup battery disposed adjacent the motor for supplying electric power when the motor is disconnected from the main electric supply.
Abstract:
An automation assembly is adapted to be connected to a door system of a motor vehicle. The automation assembly is modular and includes a frame that is fixedly secured to the motor vehicle. A motor is fixedly secured to the frame and adapted to receive power. The motor converts the power into a rotational output force. The motor includes a non-ferrous core. A set of pulleys and rollers are fixedly secured to the frame at predetermined positions to direct the path of a continuous belt. The continuous belt is fixedly secured to the door system such that the motor moves the continuous belt and the door system bidirectionally between an open position and a closed position. Sensors are used to determine the position of the door, the speed thereof and whether the door is being moved manually.
Abstract:
A method for preventing a vehicular door or window panel from pinching an obstruction extending through an aperture of the vehicle by measuring a capacitance of a field extending through the aperture using a capacitive sensor as a motor drives the panel between the open and closed positions, correlating the measured capacitance to panel position to create closing data, comparing the closing data to a reference map to create a compare value, and detecting an object in a path of the panel as it moves toward the closed position when the compare value exceeds a threshold value. The threshold value is dependent on the relative wetness of the sensor, which is determined by comparing the capacitance of the sensor at predetermined panel positions against a calibration wetness profile.
Abstract:
The invention is a sliding door assembly operable move a vehicle door between an open and a closed position. The assembly includes a motor, reversibly operable to move the door towards one of the open and the closed position. A handle is mounted to the door and a handle sensor is provided, operable to detect the grasping of the handle. When the handle is grasped, a controller activates the motor to move the door when the handle sensor is triggered. Moving the door using the handle by at least a predetermined distance causes the controller to deactivate the motor, allowing manual movement of the door.
Abstract:
An anti-pitch assembly is used in combination with a closure device of a motor vehicle. The closure device includes a closure panel, i.e., a windowpane or door, and a motor for moving the closure panel between an open position and a closed position. In the closed position, the closure panel covers an aperture, i.e., a window or door opening, of the motor vehicle. The anti-pinch assembly includes a position sensor that is disposed adjacent the motor or the closure device. The position sensor generates a position signal indicative of the position of the closure panel. A capacitive sensor measures the capacitance of a field extending through the aperture. The capacitive sensor generates a signal therefrom. A controller is electrically connected to the position and capacitive sensors. The controller receives the position and capacitive signals and transmits a signal to the motor to prevent the motor from moving the closure panel toward the closed position when the output signals deviates from a series of predetermined values for more than a predetermined period of time.

Abstract:
A proximity sensor for sensing an object in the path of or proximate to a closure panel such as a vehicle window. First and second electrodes encased in a non-conductive casing are mounted on the metallic structure near the closing edge of the aperture. The two electrodes define a capacitance CE1/2 therebetween, and parasitic capacitances CE1 and CE2 between the first electrode and chassis ground and the second electrode and chassis ground, respectively. A controller cyclically connects (1) the second electrode to a voltage reference source (Vref1) and the first electrode to chassis ground and (2) the second electrode to chassis ground and the first electrode to the reference capacitor, thereby periodically charging the capacitance CE1/2 and transferring the charge stored thereon to the reference capacitor whilst short-circuiting the parasitic capacitances. The charge on the reference capacitor, the time period required to charge the reference capacitor to a specified voltage, or a calculated value for CE1/2 are then compared against a reference value in order to derive an obstruction signal.
