    [0001] APPARATUS AND METHOD FOR DETECTING AND PREVENTING MOTOR MOVEMENT IN A DEVICE OF A BACKGROUND SYSTEM [0001] Various embodiments of the present invention relate to a motor driven system in a vehicle and more particularly, a method and apparatus for preventing unwanted movement of the motor driven system. Some vehicles are provided with windows or motorized sunroofs (e) s that move between a closed position and an open position via a motor-driven system. When the engine-driven system is de-energized and force is applied to the window or sunroof operatively coupled to the engine and the engine is allowed to be driven back or driven by the applied force, the window or the sunroof can be moved from a closed position to an at least partially open position. Therefore, it is desirable to provide an apparatus and method for detecting and preventing movement of an engine in a device or system. Typically, the problem is solved by combining the use of relay-powered motors and reduced efficiency of a worm and worm gear reducer, thereby creating the desired degree of irreversibility of the drive motor. When the motor-driven system is de-energized, the relay connects the motor windings to ground, creating a resistive torque that brakes the motor or prevents rotation of the motor. The use of relays does not control the motor speed, but only its direction. The demand for a controlled speed movement increases because it provides a regular movement and the possibility of reduced speed approaching the end of movement, the return of the end user is positive. In addition, the relays require space and their price increases. These disadvantages are solved by another technology called semiconductor relay, which consists of a MOSFET power transistor bridge. However, in the de-energized state, motor windings driven by a MOSFET are not short-circuited to ground. The result is that we lose the contribution of the electric braking effect to the irreversibility performance and the problem to solve is how to recover the desired degree of irreversibility without acting on the second parameter, that is, to say further decrease the efficiency of the worm and worm gear.

Although the drawings show various embodiments and features of the present invention, the drawings are not necessarily to scale and some features may be exaggerated to illustrate and explain embodiments. illustrative of the present invention. The exemplification presented here illustrates several aspects of the invention in a form, and such an exemplification should not be interpreted as limiting the scope of the invention in any case. DETAILED DESCRIPTION [0018] Referring now to the Figures, a vehicle door 35 is illustrated. The door 10 comprises a window or an object 12 mounted movably in an opening 14 of the door 10. The window or the object 12 is moved between a closed position and an open position by a motor driven closing system. In order to facilitate this movement, a window regulator 16 is provided. The window regulator comprises a guide rail or a pair of guide rails 18, a motor drive system 20 for moving the window 14 via a sliding element or a pair of sliding elements. 22 are movably mounted on the guide rails 18. The sliding members 22 are operatively coupled to a cable 24 which is driven or displaced via a motor drive system or a electric motor drive system 20, as is known in the state of the art. The motor drive system 20 further includes a rotor 26 for driving a worm gear 28 which meshes with a gear train gear train 30 which is configured to rotate a drum unit. cable 31 so that the cable 24 can be wound up and unwound from the cable drum 31 to move the window up and down between the open and closed positions. In one embodiment, the motor drive system 20 includes a DC motor having brush-fed windings. As shown in Figures 1 to 3, if a force not due to the motor drive system 20 is applied to the window 12 in the direction of the arrow 32, the force is also applied to the window regulator 16 in the direction of the arrow 32. This is due to the fact that the window 12 is fixed to the window regulator 16 by means of sliding elements 22. This force in the direction of the arrow 32 finally causes a corresponding torque in the direction of the arrows 32 (FIG. 3) can also be applied to a gear 30 and a worm 28 due to the fact that the pane is operably coupled to the motor drive system 20. [0020] As mentioned above, if the rotor 26 is de-energized, the rotor 26 through the worm 28 operatively coupled to a shaft 34 of the rotor 26 can be driven back or rotated due to the fact that the force in the direction of arrow 32 is applied 12. If this force in the direction of the arrows 32 is applied to the window 12 and if the rotor 26 is de-energized so that it can be driven backwards, an undesirable amount of movement of the window 12 may occur. produce. In order to prevent this undesirable amount of movement of the pane 12 through the force in the direction of the arrow 32 when the engine is de-energized, an apparatus and a method for detecting undesired movement 3032475 of the motor shaft 34 are provided here. Additionally, the apparatus and method further comprises means for limiting or preventing unwanted movement of the motor shaft 34 through the force applied in the direction of the arrows 32 once the movement of the motor shaft 34 is achieved. shaft 34 is detected. In some embodiments, the shaft 34 of the rotor 26 has a magnetic ring or an annular magnet 36 attached thereto. The motor drive system 20 further comprises a pair of Hall effect sensors 38, 40 each positioned to detect one of the north or south pole of the magnetic ring 36 as it rotates with the shaft 34. Each Hall effect sensor 38, 40 is operably coupled to an electronic control unit (ECU) 42 so that signals from the sensors 38, 40 can be sent to the ECU 42 as the shaft 34 rotates. The change of state of the sensors 38 and 40 is illustrated in FIG. 6 due to the rotation of the magnetic ring 36 in the direction of the arrows 44. [0023] In other embodiments, a rotation of the The shaft 34 of 360 degrees of rotation will be sufficient to energize the ECU 42 and enable it to determine that unauthorized rotation of the shaft 34 has occurred. In other words, a rotation of the shaft 34 causes a motor 33 of the motor drive system 20 to act as a generator due to the rotation of the rotor 26 and thus the ECU 42 is powered by the rotation of the rotor 26 which, in one case, may be unwanted rotation. In other embodiments, the ECU 42 can draw its energy from alternative sources and the signals received from the sensors 38 and 40 are simply used to indicate to the ECU 42 that an undesired rotation of the rotor 26 is produced. It is understood that the ECU 42 is operably coupled to the rotor 26 and that the ECU 42 is capable of short-circuiting motor windings 35 due to a change in an operating state of a MOSFET transistor 43 or equivalent device located on the ECU 42 so that rotation of the shaft 34 of the rotor 26 is prevented. In other words, a short-circuiting of the motor windings 35 in contact with brushes 37 of the motor via a switch 39 which are brought to the same potential / voltage, which means that they are shorted. In some embodiments, the short-circuiting of the motor windings 35 can be achieved by short-circuiting them to ground. In other embodiments, short-circuiting of the motor windings 3032475 6 can be achieved by connecting the two power brushes together to another electrical potential, for example the battery of the vehicle 45 or any other device equivalent. Still further, short-circuiting of the motor windings 35 can be accomplished by simply connecting the two power brushes together and to no other electrical potential. Short-circuiting the motor windings 35 to ground or together with another electrical potential or electrical potential, creates a resistive torque which prevents further rotation of the rotor 26 of the motor drive system 20. In one embodiment, the rotation of the shaft 34 is prevented due to the fact that the motor 33 is energized when the MOSFET transistor 43 is driven to short-circuit the motor windings 35. As such and when the motor windings 35 are short-circuited to ground or short-circuited by connecting the power supply brushes of the system together to another electrical potential (for example, battery 45) or together without any additional electric potential, a field Magnet generates a counter-electromotive force which is a linear function of the speed of rotation, this means that the faster the rotation of the rotor 26, the more we obtain a braking effect on the rotor. Since an endless screw 28 meshes with a gear or a gear wheel 30 and the gear ratio is in the range of 1 to 73, a small movement of about 1 to 2 mm of the window 12 will result in at least one turn of the shaft 34 so that the sensors 38 and 40 can detect the movement of the window 12 and can prevent further movement of the window 12 after a predetermined amount. movement of the window 12 is detected by the sensors 38 and 40. Once the predetermined amount of undesired or unauthorized movement is detected, the ECU 42 will drive a MOSFET 43 of the motor drive system 20 for short. circuit the motor windings 35 to ground or together at another electrical potential or together at no electric potential so that further rotation of the rotor 26 through the shaft 34 is prevented and thus a movement unwanted additional glass 12 will be prevented. Although ratios of 1 to 73 are described above, it is understood that ratios greater than or less than 1 to 73 are considered within the range of the various embodiments of the present invention. . Similarly, although a 1 to 2 mm movement of the window 12 is discussed, ranges of motion greater or less than 1 to 2 mm are also considered to be within the range of various embodiments of the present invention. Still further, although a 360 degree rotation of the shaft 34 is described for the predetermined amount of motion, it is understood that a rotation of plus or minus 360 degrees is considered to be within the range of various embodiments of the present invention. It is understood that the ECU 42 may comprise a microprocessor, a microcontroller or other equivalent processing device capable of executing program commands or computer-readable data to execute a computer-readable algorithm. ordered. In order to implement the prescribed functions and the desired processing, as well as the calculations for them (for example, the execution of Fourier analysis algorithm (s), algorithm steps, control processes described herein, and the like), the controller may include, but is not limited to, processor (s), computer (s), memory, storage, register (s) ( s), synchronization, interrupt (s), communication interfaces and input / output signal interfaces, as well as combinations comprising at least one of the foregoing. For example, the controller may include input signal filtering to enable accurate sampling and conversion or acquisitions of such signals from the communication interfaces. In certain embodiments, it is understood that the ECU 42 will recognize that the motor 33 is de-energized and an undesired rotation detected by the ecu 42 from the rotor shaft 26 will cause the ECU 42 to creating a resistive torque in the motor drive system 20 so that further rotation of the shaft 34 will be prevented. Figure 6 illustrates the state changes of the Hall effect sensors 38, 40 as they are driven from the top (1) downward (0) through a rotation of the 34 and the magnetic ring 36. Figure 6 illustrates the changes of state with a counter-clockwise rotation of the shaft 34 in the direction illustrated by the arrow 46. The arrows 48 illustrate a 360-degree rotation of the shaft 34, wherein the state of the sensor 40 is driven up, down and up again.
    [0004] Once the ECU 42 connected to the sensors 38 and 40 has detected at least one revolution of the shaft 34 during a de-energized state of the motor 26, the ECU 42 will determine that it is a non-shaft rotation. desired and will cause the motor 26 to be short-circuited so that further rotation of the shaft 34 is prevented. Although a 360 degree rotation is illustrated, it is of course understood that degrees of rotation greater than or less than 360 degrees can be used, which in some embodiments may depend on the number of north poles. and south of the magnetic ring as well as the number of Hall effect sensors used. Furthermore and although only one north pole and one south pole are illustrated on the magnetic ring, it is understood that various embodiments of the present invention contemplate a magnetic ring with a plurality of north and south poles of number. even (for example, two north, two south, four north, four south, etc.) or alternatively a magnetic ring with only one north pole and one south pole. As described above, the rotor 26 is short-circuited by driving or changing a state of at least one MOSFET transistor 43 driven by the ECU 42. In some embodiments, the MOSFET 43 is located on the same circuit board 49 as the ECU 42 but can be located anywhere else. In embodiments in which the Hall effect sensors are used, the power to drive the ECU 42 and / or the MOSFET transistor 43 is derived from a battery 45 operatively coupled to the motor drive system 20. Referring now to Figures 4 and 7, an alternative embodiment of the present invention is illustrated. Here, an alternative means for detecting an undesired rotation of the shaft 34 is provided as well as an alternating means for supplying the ECU 42 and driving the MOSFET transistor 43. In this embodiment, the detection and the use of a counter electromotive force is provided. In this embodiment and when the shaft 34 is rotated due to an undesired movement of the object 12, a generated voltage, due to the rotation of the shaft 34 and the rotor 26, is detected by In this embodiment, the generated voltage can also be used to power and / or excite the ECU 42 as well as to drive the MOSFET transistor 43 of the ECU 42 directly or via the control unit. ECU 42 is directly from the generated voltage of the motor drive system 20 to short-circuit the motor windings 35 so that further rotation of the rotor 26 is prevented.
    [0005] In a non-limiting embodiment, the induced voltage due to the rotation of the rotor 26 can be stored in a capacitor 51 so that the induced voltage can be stored in the capacitor 51 so that it can be used to drive the capacitor. ECU 42 and / or the MOSFET transistor 43. Alternatively, this power can be provided by a battery 45. Here, the voltage generated is caused by a rotation of the shaft 34 via a force in the direction arrows 32 as discussed above. This rotation will cause the rotor 26 to rotate in a stator of the motor drive system 20 and thus create a voltage as is known in the state of the art. For example, the motor drive system 20 operates as an electric generator in response to a mechanical energy input (e.g. a force applied in the direction of the arrows 32). As discussed above, a predetermined amount of movement of the pane 12 will cause a predetermined amount of rotation of the shaft 34 to generate the induced voltage. Once the induced voltage is generated, the ECU 42 will detect that voltage or current through any type of sensing means and the ECU 42 will be programmed to interpret that sensed voltage or current as that undesired rotation of the shaft 34 and thus drive the MOSFET transistor 43 either directly or indirectly via the induced voltage and short-circuit the motor windings 35 to ground or together to another electrical potential or simply together without additional electrical potential and thus prevent further movement of the pane or object 12. [0030] In another embodiment, the motor of the embodiment of FIGS. 4 and 7 may be a ripple motor configured to read current peaks due to rotational positions of the rotor 26 as it rotates and thereby allowing the motor drive system 20 to sense an unwanted rotation of the 26. Figure 7 is a graph illustrating the voltage generated over time through a rotation of the motor shaft 34 through a movement of the window 12. [30] FIG. 8 is a schematic illustration of an alternative embodiment of the present invention in which the object moved between a closed position and an open position is a sliding roof panel, a screen or an object 50 unlike a window 12 and the motor drive system 20 is configured to detect and prevent undesired movement of the sliding roof panel into an opening 52 of a vehicle roof 54. Although a window 12 and a roof panel 50 are described as objects whose movement is detected and thereafter prevented, it is to be understood that various embodiments of the present invention may be applied to any moving component which is driven by a electric motor drive system powered by a MOSFET transistor. For example, various embodiments of the present invention may also be embodied in any mechanism requiring irreversibility such as any window lifts including, but not limited to, window lifts as described herein. or the push-pull type, the mains and arm type and any other appropriate window lifter or any other type of sliding roof mechanism. As used herein, the terms "first", "second", and the like, here do not indicate any order, quantity, or importance, but rather are used to distinguish one element from another. and the terms "a" and "an" here do not indicate a quantity limitation, but rather indicate the presence of at least one of the referenced elements.
