Definitions
- the invention relates to a motor vehicle door arrangement, with at least one electromotive drive for opening a door leaf in a predetermined gap position in comparison to the motor vehicle body, and with at least one status sensor connected to a control unit and detecting the status of the door leaf, the control unit according to The electromotive drive is acted upon in accordance with signals from the state sensor, and the electromotive drive is preferably only acted upon when the opening of the door leaf requires this due to the state.
- Motor vehicle door assemblies use the electric motor drive, for example, to open the door leaf.
- the electric motor drive may act on a lock holder and in this way ensure the desired opening movement, as is described in detail, inter alia, in DE 10 2020 109 770 A1, which originates from the applicant.
- Another procedure in this context is the subject of DE 10 201 1 015 669 A1.
- the electromotive drive works on a lever, the rotary movement of which is converted into a movement for opening the door leaf.
- the generic prior art according to DE 10 2021 107 177 A1 relates to a door system for a motor vehicle and additionally a so-called door presenter control. That is, a power-operated presentation actuator on the motor vehicle body or on the door leaf ensures that the door leaf can be moved between a closed position and a presented or raised position.
- a power-operated presentation actuator on the motor vehicle body or on the door leaf ensures that the door leaf can be moved between a closed position and a presented or raised position.
- several different sensors are also queried. These include, for example, a position sensor for the catch of an associated motor vehicle lock or for the pawl.
- the measures according to claims 9 and 10 describe the determination of the state of the motor vehicle which prevents the normal opening of the vehicle door or the door leaf.
- the status sensor in question is queried. This can be a temperature sensor.
- the state of the art has basically proven itself when it comes to setting up the door leaf in the predetermined gap position in comparison to the motor vehicle body and, under certain circumstances, breaking through any resistance such as ice, for example.
- Such an ice-breaker function is also addressed in the prior art according to DE 10 2019 107 645 A1.
- the known teaching relies on an ice-breaker cam, with the help of which, in the sense of the ice-breaker function, the opening of the door leaf is also guaranteed when the door leaf is frozen.
- the circumferential rubber seal in relation to the door leaf ensures that the door leaf can then be opened manually or with the help of an electric motor drive when the motor vehicle door lock is open.
- the motor vehicle door lock does not open or does not open fully, or if the door leaf cannot be opened using the electric motor drive in connection with a positioning device, the icebreaker function already mentioned must be used. This regularly ensures that the door leaf is released from the surrounding rubber door seal, for example, and the frozen state can be lifted. This often requires high forces that act on the door leaf must. At this point, forces or assembly forces of several decanewtons up to several 100 newtons are conceivable.
- a so-called power-operated swing door actuator that is independent of the motor vehicle door lock is used. This ensures that the door leaf is moved between a closed and fully open position.
- a so-called presentation actuator is then additionally and additionally implemented, which is actuated as a function of the command to release a lock and a state of the motor vehicle.
- the power-operated presentation actuator is arranged independently of an additionally provided motor vehicle lock or motor vehicle door lock on a rear edge of the door leaf remote from the axis.
- the motor vehicle lock and in particular the motor vehicle door lock is usually equipped with its own electric motor drive for electric motor opening.
- the generic teaching draws on a further electric motor drive for the presentation actuator and finally a further third electric motor drive is required in connection with the power-operated swing door actuator. As a result of this separate In the final analysis, it is not necessary to monitor the electromotive drive for the door leaf and its functionality.
- the invention is based on the technical problem of further developing such a motor vehicle door arrangement in such a way that the actuating movement of the electromotive drive for opening the door leaf can be monitored, taking into account a compact and cost-effective construction.
- the invention proposes in a generic motor vehicle door arrangement that the electric motor drive acts on a body component to open the door leaf via a shift lever equipped with its own switching sensor.
- the body component in question is usually a lock holder connected to the motor vehicle body.
- the electric motor drive is arranged inside a motor vehicle lock and in particular a motor vehicle door lock.
- the electric motor drive for setting up the door leaf in the predetermined gap position is typically found inside the motor vehicle lock which is already attached to or in the door leaf.
- the motor vehicle lock in question is usually a motor vehicle door lock.
- the electric motor drive can, in addition to the so-called "ice-breaker function", also generally assume other drive functions inside the motor vehicle lock, for example basically for the electric motor opening of a locking mechanism provided inside the motor vehicle lock and in particular the motor vehicle door lock, essentially consisting of a rotary latch and pawl.
- the electric motor drive in question now works via the shift lever on the body component or the lock holder.
- the invention is based on the finding that the lock holder in question is already inside the motor vehicle lock or motor vehicle door lock or has entered it when the door leaf is in the closed state.
- the electric motor drive can initially ensure opening of the locking mechanism in a first step, in that the pawl is lifted from its latching engagement with the rotary latch in the main closed position or main latched position assumed in the closed state.
- the rotary latch usually opens with the aid of a spring and the door leaf moves away from the motor vehicle body, at least in a gap-wise manner, supported by counter-spring forces built up by a peripheral rubber door seal. If such a movement does not occur or is not observed after the electric motor has been opened, the so-called "ice breaker function" is used.
- the electric motor drive in question (or another electric motor drive present in the motor vehicle lock) works via the shift lever on the body part or the lock holder and, through the force transmission achieved in this way, ensures that the door leaf at least moves into the specified gap position in comparison is placed to the motor vehicle body.
- This predetermined gap position corresponds to the door leaf being detached from the surrounding rubber door seal inside the motor vehicle body.
- this requires forces of several decanewtons or several 100 Newtons in order to be able to set the predetermined gap position and an associated gap of the door leaf in comparison to the motor vehicle body.
- gaps of a few millimeters up to 10 mm or even more between the door leaf and the motor vehicle body have proven to be favorable in this context.
- the electric motor drive inside the motor vehicle lock and in particular the motor vehicle door lock ensures that even if the door leaf is iced over, the door leaf in question is set up at least far enough in relation to the motor vehicle body that the gap of a few millimeters that is then made available up to 10 mm or even more, an operator can grasp the door leaf and swing it open manually.
- the door leaf it is also possible in this connection for the door leaf to be equipped with its own door leaf drive, which, following the described ice-breaker function, ensures that the opened door leaf is moved to the fully open position.
- the path the door leaf has traveled in relation to the vehicle body in connection with the ice-breaker function can now be easily understood and determined, because the electric motor drive uses the shift lever equipped with its own switch sensor to move the body part or the part connected to the vehicle body. Body connected lock holder applied. With the help of the switching sensor, this movement can be traced precisely in the control unit.
- the control unit can be used to determine whether or not the specified gap position has been reached. Depending on this, the control unit can then be used, for example, to control an additional and optional door drive for the door leaf.
- the electric motor drive is preferably only acted upon when the opening of the door leaf requires this due to the condition. That is, as a rule, the electric motor drive in question is only activated when the condition of the door leaf indicates that the door leaf has frozen solid or is otherwise sticking to the peripheral rubber door seal inside the motor vehicle body.
- the state sensor that detects the state of the door leaf is provided. In other words, with the aid of the status sensor, a status that prevents normal opening of the door leaf relative to the motor vehicle body can advantageously be detected.
- This state which prevents normal opening, generally corresponds to the door leaf being frozen onto the rubber door seal or even being connected to the motor vehicle body by a continuous layer of ice, for example.
- the state sensor can also be used to detect this state that prevents the door leaf from opening normally with respect to the motor vehicle body.
- the status sensor is advantageously a temperature sensor, for example.
- a temperature sensor is already present in most motor vehicles, so that its values can be used to advantage in order to be able to draw conclusions about the condition of the door leaf.
- the status sensor can also be a displacement sensor on the door leaf.
- a door seal sensor on or in the door seal is also conceivable. This door seal sensor can be used, for example, to determine whether the door seal in question is relieved after the motor vehicle lock has been opened by the then open locking mechanism or whether it retains its compressed state. The latter then suggests a condition preventing the normal opening of the door leaf.
- any excess pressure inside the door seal, etc. can be detected, with the help of which the condition of the door leaf is evaluated.
- the status sensor can be a door-closing sensor, ie a sensor which is implemented anyway and often as a matter of routine in a motor vehicle, namely in such a way that the closed state of the relevant door leaf is detected with its help.
- the distance between the door leaf and the motor vehicle body is regularly determined using the door lock sensor (usually a door lock switch).
- the status sensor can alternatively or additionally be provided and designed as a door lock sensor for detecting a main detent position.
- the status sensor is arranged as a door lock sensor inside the previously mentioned motor vehicle lock and in particular the motor vehicle door lock. It serves namely to detect the assumption of the main detent position.
- the door lock sensor in question can typically be a rotary latch sensor that is usually present anyway, namely a sensor arranged on the circumference of the rotary latch, with the aid of which the assumption of the main locking position of the rotary latch is determined.
- a constellation sensor of the motor vehicle in addition to the status sensor for detecting the status of the door leaf, can also be evaluated by the previously mentioned control unit.
- This constellation sensor can be, for example, a rain sensor or an impact sensor or crash sensor.
- the constellation of the motor vehicle can be determined with the aid of the constellation sensor in question, for example such that the motor vehicle is exposed to rain. In such a case and when the normal opening of the door leaf relative to the motor vehicle body is prevented, particularly dangerous freezing rain can be assumed.
- the signal from a rain sensor indicates i. Together with the temperature sensor, the door leaf cannot be frozen to the door seal or the surrounding rubber door seal inside the vehicle body, because this is simply prevented by the prevailing outside temperatures. Then, for example, the state preventing the normal opening of the door leaf relative to the motor vehicle body may indicate that the associated motor vehicle lock or the locking mechanism located inside has not been fully opened.
- the constellation sensor used here and, for example, the rain sensor can be one that is also often routinely present in or on the motor vehicle and can thus be easily integrated into the motor vehicle door arrangement according to the invention.
- such rain sensors are known, for example, in connection with the activation of windshield wipers and record the size and number of droplets hitting a windshield.
- Other rain sensors work, for example, with microphones arranged in a wheel housing and are used, for example, to be able to make adjustments to the suspension and/or throttle response and shift characteristics in an automatic transmission.
- the query by the control unit can be used to the effect that in such a case the electric motor drive for opening the door leaf is simply not applied is because the triggering of the impact sensor or crash sensor indicates an accident and thus body damage that usually also means that the door is wedged against the vehicle body and can not be opened. Under certain circumstances, this would lead to damage to the electric motor drive if it were to be acted on anyway.
- the procedure is such that the electric motor drive for opening the door leaf is acted upon at least up to an ice-breaker position that can be detected using the switching sensor.
- the ice-breaker position regularly corresponds to the predetermined gap position or a specific value, generally stored in the control unit, for the gap between the door leaf and the motor vehicle body achieved in this way. This means that the movement of the electric motor drive and consequently also of the door leaf relative to the motor vehicle body can be detected via the switch sensor assigned to the shift lever and transmitted to the control unit. Only when the switching sensor determines that the icebreaker function has been reached or the associated gap has been reached does the control unit ensure that the electric motor drive is stopped.
- the electric motor drive is advantageously only required and acted upon when the condition of the door leaf actually requires it, ie the door leaf is generally frozen solid relative to the door seal or peripheral door rubber seal.
- the electric motor drive is protected overall and actually only used when this is necessary and required for the ice-breaker function.
- the electric motor drive and the drive elements connected thereto can also be designed in such a way that, viewed over the life of the motor vehicle, only a relatively limited number of operations can be completed. Of course, this can also be changed depending on the region. That is, in the case of a motor vehicle that is delivered, for example, to arctic or cold regions, the electric motor drive with its associated drive elements is designed to be correspondingly stronger compared to the delivery situation in, for example, hot areas or regions.
- the electric motor drive usually works via a transfer lever on the previously mentioned shift lever.
- the shift lever is also and generally arranged inside a lock case of the previously mentioned motor vehicle lock.
- a bearing that is on the same axis as the rotary latch in the lock case has also proven to be particularly advantageous. This is because the axis of the rotary latch is in any case designed to be particularly stable and solid with a corresponding bearing mandrel that is anchored in the lock case.
- the mentioned forces on the part of the shift lever can be transferred without any problems to the lock holder acted upon by it or, in general, to the body component for opening the door leaf.
- the motor vehicle door arrangement according to the invention is, very generally and according to a broad understanding, any Body-connected flap assembly. That is, the motor vehicle door arrangement is not necessarily designed as a motor vehicle swinging door. In principle, it can also be a bonnet, a tailgate, a loading flap, a tank flap, etc.
- the motor vehicle door arrangement can just as well be designed as a motor vehicle sliding door arrangement.
- a particularly compact and functional embodiment is provided according to the invention, which is equipped with synergetic advantages. Because the electric motor drive for opening the door leaf is generally a part of a motor vehicle lock and in particular a motor vehicle door lock that is provided anyway. As a result, a separate housing, additional attachments, etc. are expressly unnecessary.
- the electric motor drive inside the motor vehicle lock can not only be used for opening the door leaf and thus the ice-breaker function described, but also takes on other functions inside the motor vehicle lock.
- An example of this is the electromotive opening of the locking mechanism consisting of a rotary latch and a pawl. This is where the main advantages can be seen.
- FIG. 1 shows the motor vehicle door arrangement according to the invention schematically
- FIGS. 2A to 2C the motor vehicle door arrangement also reduces the essential components in different functional positions.
- the figures show a motor vehicle door arrangement which has at least one door leaf 1 which can be swung open and opened relative to a motor vehicle body 2, as indicated by a corresponding arrow in FIG.
- the door leaf 1 can be pivoted about an axis that is not expressly shown.
- the door leaf 1 is a side door leaf, which of course is only an example and does not apply to any restrictions.
- the door leaf can in principle also be a tailgate, a front hood, etc.
- the basic structure of the motor vehicle door arrangement shown includes at least one electric motor drive 3, which is only shown in the figures as an arrow or box for reasons of clarity.
- the electric motor drive 3 usually has an electric motor and a downstream gear, with the help of which it works via a transfer lever 4 to a shift lever 5 in the exemplary embodiment.
- the transfer lever 4, like the shift lever 5, is mounted in a lock case 6.
- FIG. 2a shows the locking mechanism 7, 8 in a main locking state or main locking state or in its main locking position.
- the lock case 6, the locking mechanism 7, 8 mounted therein, the transfer lever 4, the shift lever 5 and also the electric motor drive 3 represent components of a motor vehicle lock and in particular a motor vehicle door lock, which in Fig. 1 is represented by an enclosing housing 9 is indicated, in which the entire components are located.
- the motor vehicle lock or its locking mechanism 7, 8 interacts in the usual way with a body component 10 of the motor vehicle body 2.
- the body component 10 in question of the motor vehicle body 2 is, as shown in FIG connected to the motor vehicle body 2 lock holder 10.
- the lock holder 10 is fully retracted into the locking mechanism 7, 8, which is in the main locking position. This corresponds to the door leaf 1 being closed relative to the motor vehicle body 2 .
- At least one control unit 11 is realized, which according to the exemplary embodiment can be arranged inside the motor vehicle lock housing 9 or outside. With the aid of the control unit 11, not only is the electric motor drive 3 acted upon, but signals from a status sensor 13 can also be detected and evaluated. The state of the door leaf 1 is detected with the aid of the state sensor 13, as has already been described at the outset and is explained in more detail below.
- the electric motor drive 3 is used to set up the door leaf 1 in a predetermined gap position, which belongs to a gap S shown in FIG. 2C in comparison to the motor vehicle body 2 .
- the gap S can assume values of several millimeters up to 10 mm and more.
- the electromotive drive 3 is only acted upon when the opening of the door leaf 1 requires this due to the condition.
- the status sensor 13 is provided for this purpose.
- the status sensor 13 is a temperature sensor 13, which may be arranged inside the motor vehicle body 2 in any case and may be mandatory.
- the control unit 11 evaluating the signals from the status sensor 13 ensures that the electromotive drive 3 for opening the door leaf 1 moves to the position shown in FIG Fig. 2C shown predetermined gap position with the associated gap S is transferred in comparison to the motor vehicle body 2 (ice breaker function).
- Electric motor drive 3 Because of that Electric motor drive 3 is typically applied only in rare cases and depending on the state of the door leaf 1, the electric motor drive 3 can be spared otherwise. However, it is also possible for the electric motor drive 3 inside the motor vehicle lock to be used alternatively and additionally to open the locking mechanism 7, 8, although this is not shown in detail.
- the design is such that the electric motor drive 3 acts on a body component 10 and specifically the lock holder 10 for opening the door leaf 1 via the shift lever 5 equipped with its own switching sensor 12 .
- the electric motor drive 3 works via the transfer lever 4 on the shift lever 5. This can be understood by comparing the function sequence in FIGS. 2A to 2C.
- FIG. 2A shows the closed state of the door leaf 1 in relation to the motor vehicle body 2. If, starting from this, the electric motor drive 3 acts on the transfer lever 4 during the transition from FIG. 2A to FIG counterclockwise movement about its axis, the transfer lever 4 ensures, via a stop 5a arranged on the shift lever 5 and acted upon by it, that the shift lever 5 in turn is pivoted clockwise about the common axis with the rotary latch 7 as indicated.
- the clockwise pivoting movement of the shift lever 5 initiated by the electric motor drive 3 ensures that the Motor vehicle lock as a whole and thus also the door leaf 1 is removed from the motor vehicle body 2 until the gap S occupied in FIG. 2C at the end of this movement is present between the door leaf 1 and the motor vehicle body 2.
- forces are typically transmitted to the lock holder 10 by the electric motor drive 3, which can amount to a number of decanewtons and can assume values of up to 70 decanewtons or 700 newtons.
- frozen door leaves 1 can also be detached in relation to the motor vehicle body 2 in the sense of the ice-breaker function realized in this way and transferred to the gap position associated with gap S in FIG. 2 .
- the state sensor or temperature sensor 13 is used to detect a state that prevents the door leaf 1 from opening normally in relation to the motor vehicle body 2 .
- This state of the door leaf 1 corresponds, for example, to the fact that the door leaf 1 is frozen to a peripheral door seal or rubber door seal in the motor vehicle body 2 that is not expressly shown.
- the control unit 11 now evaluates signals from this state sensor or temperature sensor 13 in the exemplary embodiment.
- signals from a constellation sensor 14 of the motor vehicle can also be evaluated by control unit 11 in addition and as a supplement.
- This constellation sensor 14 is, for example, a rain sensor 14.
- the control unit 11 now evaluates both the state sensor 13 and the constellation sensor 14 in combinatorial fashion in order to act on the electric motor drive 3 . Only when the control unit 11 determines that the door leaf 1 is actually in or has assumed the state that prevents normal opening relative to the motor vehicle body 2 does the control unit 11 ensure that the electric motor drive 3 is acted upon accordingly in order to move the door leaf 1 - as described - to be able to stand up relative to the motor vehicle body 2, namely, according to the exemplary embodiment, until the predetermined gap position and the gap S shown in FIG. 2C is reached.
- the associated movement of the shift lever 5 can be monitored in this context, because namely the shift lever 5 using the shift Sensor 12 is scanned, the signals in turn experienced by the control unit 1 1 an evaluation.
- the overall design is such that the electric motor drive 3 is acted upon to open the door leaf 1 at least up to an ice-breaking position that can be detected using the switching sensor 12 .
- this ice-breaking position corresponds to the door leaf 1 occupying the gap S in relation to the motor vehicle body 2, as illustrated in FIG. 2C. This includes values of the gap S from a few millimeters up to 10 mm or even more.
- the control unit 11 can then act on a door drive that is not expressly shown and is additionally and optionally provided, which in turn ensures that the door leaf 1 can be opened completely with the help of the door drive starting from the gap-wise open position.
- the door leaf 1 can then also be closed by motor. A purely manual opening of the door leaf 1 is also possible.
