Abstract: A motor control system includes a variable voltage supply in signal communication with a direct current (DC) motor. The DC motor includes a rotor induced to rotate in response to a drive current generated by a variable supply voltage delivered by the voltage supply. The rotation of the rotor generates a mechanical force that drives a component. A ripple count circuit is configured to filter the drive current based on a rotational speed (?) of the rotor, and to generate a pulsed output signal indicative of the rotational speed (?) of the rotor and a rotational position (?) of the rotor.

Abstract: A bracket for securing a pulley or deflection ramp to a guide rail of a window regulator. The bracket having: a main body portion; a pulley or ramp support extending away from the main body portion and forming a rotational pulley axis or a ramp attachment; and a flange for transferring loads applied to the pulley or the deflection ramp, wherein the main body portion extends over a top portion of the pulley or deflection ramp and the flange extends away from a distal end of the main body portion.

Abstract: A motor drive system configured to detect and prevent undesired movement of an item that is configured to be driven by the motor drive system. The motor drive system having: an electronic control unit operatively coupled to a rotor of the motor drive system, the electronic control unit being configured to detect undesired rotation of a shaft of the rotor, wherein the undesired rotation of the shaft is not caused by a force applied by the rotor; and wherein the electronic control unit of the motor drive system is configured to short windings of the motor drive system after a predetermined amount of undesired rotation of the shaft is detected by the electronic control unit such that further rotation of the rotor is prevented.

Abstract: The invention relates to a sheath stop including: a hole through which a window lift cable is to pass; and a sheath abutment for locking the sheath of the window lift cable on one side of the sheath stop and wherein, on the other side of the sheath stop, the sheath stop includes a shaft provided so as to be mounted onto a bracket of the sheath stop such that the sheath stop has a freely rotatable mounting configuration on the bracket. The shaft extends transversely to the main orientation of the passage hole, and the passage hole has a partial side clearance that allows the cable a degree of bending freedom within a plane perpendicular to the shaft when the sheath stop freely pivots about the shaft.

Abstract: A window lifter is provided. The window lifter having: first and second guide rails; first and second sliders for driving a window, the first and second sliders being guided in translation by the first guide rail and the second guide rail, respectively; a cable system for driving the sliders along the first and second guide rails, the cable system comprising a cable extending between the first and second guide rails for connecting to corresponding ends of the first and second guide rails, respectively, the first guide rail comprising a holder for fastening the cable between the two corresponding ends of the first and second guide rails that the cable connects.

Abstract: A vehicle window regulator includes a fixing lug including a first part for fixing to a window guide rail having a window-guiding direction and a second part for fixing to a vehicle body. The second part defines a plane, and a normal line perpendicular to the plane that is inclined relative to the window-guiding direction. The normal line is preferably inclined at an angle of approximately 45° relative to the window-guiding direction. The lug can be fixed in the vehicle body without the lug turning on itself during fixing by screwing, for example.

Abstract: A method of fabricating a window regulator includes the step of providing a cable, a window connection on the cable, sheaths for protecting the cable, cable direction-changers, a cable winding drum, a drum support plate, and springs. The method further includes the steps of passing the cable between the direction-changers, inside the springs, inside the sheaths, and around the drum. The method further includes the steps of tensioning a first cable run extending through a first sheath between a first direction-changer and the drum, tensioning the first cable run urging the first sheath against the drum support plate, and compressing a first spring between the first sheath and the support plate. The method further includes the steps of locking the drum against rotation, compressing a second spring between a second sheath and the support plate, and locking the second spring. A window regulator can include the above features.

Abstract: A window regulator cable tensioner includes a screw and nut assembly having an irreversible thread lead angle, a first spring to absorb reversible slack in the cable, and a second spring to actuate movement of the screw and nut assembly. The stiffness of the first spring is greater than the stiffness of the second spring. The cable tensioner absorbs the reversible slack in the cable differently from irreversible slack in the cable.

Abstract: A method of limiting a closing force of a motorized opening on a sealing line of a motor vehicle includes the step of calculating the closing force at each instant in a displacement of the opening while closing. The closing force is calculated by a difference between a force applied to the opening when an edge of the opening is situated in an area of or squashes the sealing line and a force applied to the opening just before the edge of the opening penetrates into the area of or squashes the sealing line. The method further includes the step of stopping an electric motor driving the opening when the closing force reaches a constant predetermined value. The closing force can be limited regardless of the climatic conditions or the operating conditions of the motor vehicle.

Abstract: A sliding door carriage for a vehicle includes a first point for fixing a first cable strand for driving in a first direction, and a second point for fixing a second cable strand for driving in a second direction. Each fixing point is offset toward a rear of the sliding door carriage relative to a direction of driving by the respective cable strand. The sliding door carriage can be included in a sliding door driving system, and the sliding door driving system can be included in a vehicle. The bulk of the sliding door driving system in a body of a vehicle can be reduced.

Abstract: The invention relates to a method for obtaining a criterion for detecting obstacles in a closure movement of a motor-driven opening. The obtaining method includes the step of determining a speed of rotation of a motor shaft and the step of determining a quantity representative of a motor voltage. The detection criterion is then obtained by a step for calculating the criterion according to the speed of rotation of the motor shaft and the quantity representative of the motor voltage. This makes it possible to obtain a criterion, which is both robust and inexpensive, for detecting obstacles in a closure movement of a motor-driven opening.

Abstract: A closure system for a door opening includes a striker having a support plate and a striker wire, and a lock having a bolt actuated by a detent pawl and adapted to retain the striker wire in the door opening. The lock and the striker each have at least one attachment feature that is complementary and separate from the bolt and the striker wire. The striker is thus secured to the lock during the installation of the closure system on the vehicle.

Abstract: A printed circuit board (PCB), in particular for an electric motor, has two opposite main surfaces with at least one main surface carrying electrical components. A plurality of outer end faces extend between the two opposite main surfaces. One of the outer end faces is provided with a metallization that is connected to a ground conductor on the PCB.
