Definitions
- the invention relates to a drive device for motor vehicle applications, in particular for the electric motor adjustment of a motor vehicle control element such as a motor vehicle door or motor vehicle flap, with an electric motor, furthermore with a transmission following the electric motor, and with at least one first sensor and first probe element, the first sensor and the first probe element are movable relative to one another and, taken together, detect an absolute position of the motor vehicle actuating element.
- a motor vehicle control element such as a motor vehicle door or motor vehicle flap
- Drive devices for motor vehicle applications typically use an electric motor which is operated with the low voltage provided by a motor vehicle, for example an accumulator. Due to the limited power of the electric motor, it is necessary to use the gear unit following the electric motor to translate the rotary movements of the electric motor so that even voluminous and correspondingly heavy motor vehicle control elements such as motor vehicle doors or motor vehicle flaps can be moved with the aid of the drive device in question. In principle, other motor vehicle control elements such as window panes, sliding doors, tank lids, front hoods, etc. can also be moved using such drive devices, specifically adjusted by an electric motor.
- a relative movement for example, of an output gear of the transmission with an associated probe element compared to a on the other hand, fixedly mounted sensor can be detected.
- Such drive devices or adjusting devices for the automatic adjustment of an adjusting element are described, for example, in DE 10 2011 103 406 B4.
- the adjustment of the adjusting element is carried out in a manner dependent on the associated detection signal of the sensor.
- the sensor is set up to vary the shape, strength, alignment and / or a frequency of an electric field generated by it as a function of a control signal for setting its detection sensitivity.
- the actuating device is to be improved with regard to its fault tolerance with simple means.
- another drive device works with a Hall sensor for position detection. At least one Hall sensor element and a magnetic structure that moves when the associated actuator is displaced relative to the at least one Hall sensor element is used for path detection.
- the magnetic structure can be a plurality of magnetic marks arranged next to one another in the axial direction.
- the known adjusting device has an optical sensor for contactless detection of the position of the adjusting element along its adjustment path.
- the sensor is arranged with respect to a reference surface in such a way that it detects a relative movement with respect to the reference surface when the associated drive is actuated.
- An evaluation unit can determine the current position of the adjusting element from the relative movement data recorded by the sensor, and indeed absolutely.
- a light source aligned with the reference surface and a light detector are assigned to the optical sensor.
- the light detector With the aid of the light detector, light reflected from the reference surface is evaluated and corresponding image information can be derived from which the relative movement data are then derived.
- This is relatively complex, especially since the light source, the light detector and also the reference surface are absolutely necessary in addition to the optical sensor. Overall, this allows an absolute position of the motor vehicle control element to be derived and a position determination that is as precise as possible can be achieved.
- the associated constructive and financial effort is enormous. A relatively large amount of installation space is also required to implement the known actuating device.
- the invention is based on the technical problem of providing such a drive device for motor vehicle applications develop that a structurally simple and inexpensive and as compact as possible embodiment for detecting the absolute position of the actuator is made available.
- a generic drive device for automotive applications within the scope of the invention is characterized in that the first sensor and / or the first probe element are mechanically form-coded to clearly define their relative position to each other and the absolute position of the actuating element are connected to the transmission.
- the first probe element and / or the first sensor is generally arranged in or on an output gear of the transmission.
- the design is usually made in such a way that the output gear and an upstream gear of the transmission are equipped with a projection and a corresponding recess.
- the projection and the corresponding recess can only be mounted in a specific angular position to one another, following the key / keyhole principle.
- the projection and the recess are preferably implemented and provided in a plane arranged parallel to the plane of the tooth.
- the first probe element or the first sensor are therefore located on the output side of the transmission due to their arrangement in or on the output gear of the transmission. In this way, measurement signals from the first sensor are not falsified by possible gear backlash or also backlash of the electric motor. Because the output-side arrangement of the first probe element or the first sensor in the output gear of the transmission ensures that with their help the position of the motor vehicle control element directly connected to the output gear can be detected absolutely.
- the absolute position is recorded according to the “Poka Yoke” principle. This means a Japanese principle after technical precautions are taken to prevent errors immediately. In the context of the present invention, these precautions are the projection on the gearwheel of the transmission and the corresponding recess on the output gearwheel or vice versa.
- the projection and the recess can only be mounted in one (single) angular position to one another.
- the feeler element arranged in the output gear assumes a defined and previously determined angular position in comparison to the associated (stationary) sensor.
- This previously determined position of the feeler element in comparison to the sensor can be used, for example, as a “zero position” for subsequent movements of the motor vehicle control element connected to the output gear. Since each revolution of the associated output gear corresponds, for example, to an associated adjustment angle of a motor vehicle side door as a motor vehicle actuating element, the position actually assumed by the motor vehicle actuating element after being acted upon with the aid of the drive device can be recorded absolutely based on this "zero position".
- the projection and the recess are typically provided in the plane arranged parallel to the plane of the tooth.
- the output gear and the upstream gear can be equipped from the outset with the projection and the recess on the manufacturing side, so that additional adjustments are not required.
- the additional arrangement of the projection and the recess in the plane arranged parallel to the tooth plane also provides a particularly compact and small-sized construction, which is structurally much simpler and therefore more cost-effective compared to the generic prior art according to DE 202009018219 U1 . This is where the main advantages can be seen.
- the output gear typically has an associated spring.
- the design is usually made in such a way that the output gear is pretensioned or is pretensioned with the aid of the spring to release play.
- the spring is generally designed as a spiral spring and in this way can act on the output gear on the circumferential side. This again promotes a particularly compact and small-sized design.
- a further second sensor and possibly a second probe element are provided in addition to the first sensor and the first probe element.
- the additional second sensor and the optional second probe element are usually provided on the drive side for determining a drive load in connection with the first sensor and / or the first probe element.
- the additional second sensor and the optional second probe element are on the other hand on the drive side.
- an angle of rotation between the electric motor or its output shaft on the one hand (drive side) and the output gear on the other hand (output side) can be determined when the motor vehicle control element connected to the output gear is acted upon.
- This angle of rotation represents a measure of the drive load or the counterforce acting on the drive device by the motor vehicle actuating element to be acted upon. This can be a holding force as a result of the friction to be overcome when the motor vehicle actuating element is acted upon from a rest position, or it can be simply the inertia of the motor vehicle actuating element.
- the angle of rotation in question is a measure of the drive load to be handled by the drive device.
- the angle of rotation can now be adjusted using the first Sensor and possibly the first probe element and the second sensor and optionally the second probe element are determined. This is because the angle of rotation ultimately corresponds to a relative rotational movement between the output shaft of the electric motor and the output gear, which must be completed before the motor vehicle control element is even moved or when the motor vehicle control element is moved. With the aid of a control unit evaluating the signals from both sensors, the angle of rotation and thus the drive load can now be determined.
- the calibration curve or the angle of rotation can be measured over all operating ranges, i.e. H.
- temperature effects, different drive loads, etc. can be taken into account.
- the gear stiffness can also be taken into account.
- the gear stiffness can be calculated constructively.
- the transmission stiffness can be determined in connection with the calibration curve mentioned above, in which the respective angle of rotation is recorded as a function of the drive load and stored as a calibration curve in the memory associated with the control unit.
- the first probe element and the first sensor are typically a Hall sensor as the first sensor and an associated magnetic element or a permanent magnet as the first probe element.
- the second sensor and the optional second probe element can be constructed in a comparable manner.
- the second sensor can also be designed as an acceleration sensor without a second probe element.
- other sensor designs are also possible within the scope of the invention, for example in such a way that the respective sensor is equipped as a light-sensitive optical sensor, while the probe element is designed as an associated light source, possibly with a reflective surface, markings, etc.
- a blocking element for fixing the electric motor and / or the transmission can also be implemented.
- the blocking element advantageously acts on an output shaft of the electric motor.
- a holding function for the motor vehicle actuating element acted upon by the drive device can be implemented. If, for example, the motor vehicle actuating element in the form of a motor vehicle door or motor vehicle flap is to be fixed in a certain position, the blocking element ensures the corresponding blocking and thus fixing of the motor vehicle actuating element.
- a precise and reproducible start-up of the motor vehicle actuating element starting from a rest position of the motor vehicle actuating element can hereby be implemented, in which case the rest position is additionally determined with the aid of the blocking element, if necessary.
- a drive device is made available which provides an absolute position measurement of the motor vehicle control element in a structurally simple manner and taking into account a compact design.
- a particularly robust operation is thereby made available. Since the first probe element and the first sensor are advantageously implemented on the output side, the position of the motor vehicle actuating element is measured without gear backlash.
- the design ensures that the first probe element is advantageously arranged in the output gear of the transmission, whereas the first sensor is stationary and at a distance from it, so that the sensor as a whole is not in the areas of the electric motor via the transmission and finally the connected motor vehicle. Control element defined power flow is involved. As a result, any influencing of the force acting on the sensor's measurement signal is not to be expected.
- the additionally provided blocking element ensures that the drive device can be stiffened in a practically switchable manner. As a result, the breakaway behavior of the transmission including the connected motor vehicle control element can be effectively controlled as required. This is where the main advantages can be seen.
- FIG. 1 shows the drive device according to the invention in a perspective overview, partly in an exploded view
- FIG. 2 shows the object according to FIG. 1 in a side view and in a top view
- FIG. 3 shows a modified embodiment with an additional blocking element schematically and FIG. 4 shows the function of the blocking element according to FIG. 3.
- a drive device for automotive applications is shown.
- the drive device which will be explained in detail below, is used for the electric motor adjustment of a motor vehicle control element such as a motor vehicle door 1 only indicated schematically in FIG. 2.
- the motor vehicle door 1 may be a motor vehicle side door, which is also shown in FIG 2 can perform indicated pivoting movements.
- a motor vehicle door 1 can also be a motor vehicle flap and, in particular, a motor vehicle tailgate.
- the drive device used to adjust the motor vehicle control element has for this purpose and quite fundamentally an electric motor 2 which operates on a gear 3, 4 following the electric motor 2.
- the transmission 3, 4 is composed of a driven gear 4 and a gear 3 connected upstream of the driven gear 4, which in turn is acted upon directly or indirectly by the electric motor 2.
- the basic structure of the drive device is also equipped with at least one first sensor 5 and one first probe element 6.
- the first sensor 5 and the first probe element 6 can be moved relative to one another.
- the first sensor 5 and the first probe element 6 together detect an absolute position of the actuating element or the motor vehicle door 1 in the example.
- the absolute position of the motor vehicle actuating element or motor vehicle door 1 corresponds to an opening angle ⁇ of motor vehicle door 1 or motor vehicle side door indicated in FIG. 2 with respect to a motor vehicle body that is merely indicated.
- the first sensor 5 is designed as a Hall sensor.
- the first probe element 6 is a permanent magnet which is arranged in the output gear 4.
- Rotational movements of the output gear 4 and consequently a change in the swivel angle ⁇ of the motor vehicle control element connected to the output gear 4 or the motor vehicle door 1 in the example with respect to the body correspond to the fact that associated field changes are detected by the first sensor 5 or Hall sensor.
- the first sensor 5 or Hall sensor is connected to a control unit 7. Since the first sensor 5 or Hall sensor is designed to be stationary and the mentioned rotary movements correspond to a rotary movement of the output gear 4 and therefore of the first probe element 6 or the permanent magnet, such rotary movements lead to field changes. These field changes are detected by the Hall sensor 5 and evaluated with the aid of the control unit 7.
- the permanent magnet or the first probe element 6 is designed in such a way that its rotational movement, together with the output gear 4, changes the magnetic field detected by the Hall sensor 5 and oriented perpendicular to the Hall sensor 5. This results in Hall signals which can be registered by the Hall sensor 5 and which are recorded and evaluated by the control unit 7.
- the control unit 7 can infer the angular position or the angle ⁇ of the motor vehicle actuating element or the motor vehicle door 1 with respect to the body.
- an absolute position of the motor vehicle control element or the motor vehicle door 1 can also be determined in this context with the aid of the first sensor 5 and the first probe element 6, the first sensor 5 and the first probe element 6 are mechanically form-coded to clearly define their relative position to one another the gear 3, 4 connected.
- shape coding to be described in more detail below can be used to determine the absolute position of the motor vehicle actuating element or motor vehicle door 1 in the example.
- the shape coding between the first sensor 5 and the first probe element 6 and the unambiguous determination of their relative position to one another is accomplished and implemented within the scope of the exemplary embodiment in such a way that a projection 9 and a recess 8 are designed to correspond to one another and interlock.
- the gear 3 of the transmission 3, 4 connected upstream of the output gear 4 is equipped with a projection 9.
- the projection 9 is arranged on the circumference of the gear 3 and sweeps over an angular segment of the circumference of the gear 3.
- the corresponding recess 8 is a recess 8 on the output gear 4, which is also provided as an angular segment on the circumference of the output gear 4.
- the design and the shape coding achieved is such that the projection 9 and the corresponding recess 8 have a comparable circumferential extent so that the projection 9 on the gear 3 and the corresponding recess 8 on the output gear 4 are only in one (single) relative position can be brought into engagement with one another.
- the projection 9 and the recess 8 are each provided and placed in a plane arranged parallel to a tooth plane Z. This can be seen in particular on the basis of the side view in FIG. In this case, the projection 9 is provided on the output gear 4, whereas the gear 3 upstream of the output gear 4 is in this case equipped with the recess 8 corresponding to the projection 9.
- the projection 9 and the recess 8 on the two intermeshing gears 3, 4 ensure that both gears 3, 4 can only be assembled and engaged in a single relative angular position.
- the form coding required according to the application is made available, namely that the two gears 3, 4 can only and exclusively be mounted in this single and previously described relative angular position to one another.
- a “zero position”, as it were, of the motor vehicle actuating element and specifically of the motor vehicle door 1 is also established. As soon as the electric motor 2 is energized after assembly, this takes place accordingly, starting from the previously defined “zero position”.
- each revolution or partial revolution of the output gear 4 corresponds to a changed magnetic field strength, which can be detected with the aid of the fall sensor 5 and reported to the control unit 7.
- the absolute position of the motor vehicle control element or the associated angle ⁇ can then be determined from this. This is ensured by the specific assembly of the two gears 3, 4 in the exemplary embodiment to one another, which, following the key / keyhole principle, can only be assembled in one angular position to one another.
- the output gear 4 also has a spring 10 which, in the exemplary embodiment, is designed as a spiral spring.
- the spring 10 ensures that the output gear 4 is acted upon on the circumferential side.
- the spring 10 is supported with its one end on a bridge element 11 which, as a molded plastic part, engages over the output gear 4 and is designed to accommodate the first sensor 5.
- the other end of the spring 10 engages the output gear 4.
- the spring 10 ensures that the teeth of the output gear 4 with their one tooth flanks on corresponding tooth flanks of the upstream of the output gear 4 Gear 3 of the gear 3, 4 are in contact.
- the drive device according to the invention in addition to the first sensor 5 and the first probe element 6, is equipped with a further second sensor 12 which interacts with a second probe element 13 according to the exemplary embodiment.
- the second sensor 12 is again designed as a Hall sensor and mounted in a stationary manner.
- the second probe element 13 is again a permanent magnet 13 that is relatively movable with respect to the Hall sensor 12.
- the permanent magnet 13 is connected to an output shaft of the electric motor 2, specifically designed as part of a blocking device 14, 15.
- this blocking device 14, 15 is composed of a blocking disk 14 mounted on the output shaft of the electric motor 2 and an additional blocking element 15.
- the blocking element 15 can engage circumferentially in the blocking disk 14 and in this way ensure that the entire drive device is blocked.
- the blocking element 15 is acted upon by a separate and additional electric motor 16 according to the exemplary embodiment, which for this purpose sets a drive pulley 17 with a cam 18 located on it in rotation. With the help of the cam 18, the blocking element 15 is linearly moved back and forth and in this way can interact on the outer circumference with a contour provided there in such a way that the blocking disk 14 and consequently the entire drive device are blocked.
- an active holding function of the drive device and consequently of the motor vehicle actuating element or motor vehicle door 1 can be implemented and implemented.

- this can result in additional rigidity in the entire drive device with regard to the flow of force be introduced. This is only effective when the hold function or the blocking device 14, 15 is activated.
- a particularly precise and reproducible start-up of the motor vehicle control element can be made available as a result.
