Description

The proposed solution relates to an adjusting device and a method for adjusting an adjusting part on a vehicle.

Adjusting devices for the power-operated adjustment of an adjustment part on a vehicle are widely known. For example, adjustment parts in the form of vehicle doors are opened or closed by a motor in response to a detected operating event. It is also known to support a muscle-force-operated adjustment of an adjustment part, for example in the form of a vehicle door, with a motor, so that the muscle force required by a person to adjust the adjustment part is as small as possible.

In this context, for example, capacitive sensors in a door handle of a vehicle door for detecting a hand that encompasses the door handle are known in order to trigger the unlocking of a lock of the vehicle door and then to open the vehicle door with a motor. Alternatively, optical sensors are also known in order to detect an operator control event. For example, it is known to evaluate a kicking movement with one foot at the rear of a vehicle as an operating event and then to open a tailgate of a vehicle by an external force.

In the course of increased comfort requirements, however, there is still a need for improved and / or alternative adjusting devices and methods implemented with them for adjusting an adjusting part on a vehicle.

• - einen motorischen Antrieb für die Erzeugung einer auf ein Verstellteil wirkenden Antriebskraft,
• - wenigstens ein Sensorelement zur Erfassung eines von einer Person ausgelösten Bedienereignisses und
• - eine Steuerelektronik zur Steuerung des motorischen Antriebs in Reaktion auf das durch die Person ausgelöste Bedienereignis, um das Verstellteil mithilfe des motorischen Antriebs entlang einer Schließrichtung in Richtung einer geschlossenen Stellung des Verstellteils zu verstellen, wenn sich das Verstellteil in einer geöffneten Stellung befindet.

Über das wenigstens eine Sensorelement und die Steuerelektronik ist hierbei ein Bedienereignis zum Schließen des Verstellteils erfassbar, bei dem die Person in einem Abstand zu dem sich in einer geöffneten Stellung befindlichen Verstellteil mit einer Hand eine Geste in Richtung der geschlossenen Stellung des Verstellteils ausführt. Die Steuerelektronik ist dann weiterhin eingerichtet, den motorischen Antrieb in Reaktion auf diese Geste zum Verstellen des Verstellteils in Schließrichtung anzusteuern.With this aim, an adjustment device is proposed which comprises at least the following:

• - a motor drive for generating a driving force acting on an adjustment part,
• - At least one sensor element for detecting an operating event triggered by a person and
• - Control electronics for controlling the motorized drive in response to the operating event triggered by the person in order to adjust the adjusting part with the aid of the motorized drive along a closing direction in the direction of a closed position of the adjusting part when the adjusting part is in an open position.

Via the at least one sensor element and the control electronics, an operating event for closing the adjustment part can be detected in which the person at a distance from the adjustment part in an open position makes a gesture in the direction of the closed position of the adjustment part with one hand. The control electronics are then also set up to control the motorized drive in response to this gesture for adjusting the adjustment part in the closing direction.

The solution proposed according to this aspect consequently provides that a gesture can be detected without contact, with which a person clearly indicates that the adjustment part should be closed. The gesture and the adjusting movement thus correlate, while this is not the case, for example, with my kicking movement with a foot and a subsequent opening of a tailgate of a vehicle.

The proposed solution accordingly includes in particular that a person virtually pushes the adjustment part in the direction of the closed position and a sensor system of the adjustment device, which is formed with at least one sensor element and the control electronics, detects a corresponding (closing) gesture without contact and in response to this, closes the Adjusted part triggered without the person actually having to attack the adjustment part.

For example, in one embodiment variant, the control electronics are set up to control the motor drive in response to the detected operating event (with the gesture executed in the direction of the closed position) while maintaining a minimum distance between the adjustment part and the person's hand in order to adjust the adjustment part in the closing direction. Maintaining a minimum distance from the person's hand is understood here in particular to mean that an adjustment movement of the adjustment part away from the person's hand is controlled by a motor in such a way that the adjustment device always tries to keep the adjustment part at a distance from the person's hand. This can then have the consequence, for example, that the adjustment part is adjusted more quickly when the person's hand has approached the adjustment part so far that the minimum distance is not reached. One possible embodiment variant provides, for example, that the adjustment movement of the adjustment part follows the person's hand. A distance control is implemented for this purpose via the control electronics. This means, for example, that a distance between the hand and the adjustment part is detected via the at least one sensor element and, if necessary, measured, and at least one measured value of the at least one sensor element representative of the detected distance is incorporated as a control variable into a control logic of the control electronics that operates the motor drive controls to close the adjustment part.

For example, it is provided that the minimum distance to be maintained between the adjustment part and the person's hand is dependent on the distance between the person's hand and the adjustment part that the hand assumed at the beginning of the gesture recorded as an operating event. For example, it is provided in this context that the minimum distance to be maintained corresponds precisely to the distance that was present at the beginning of the gesture assessed as an operating event. If the hand is then guided in the closing direction, for example in the case of a vehicle door as an adjustment part in the direction of the vehicle interior, the adjustment part follows this hand movement by correspondingly activating the motor drive.

The start of a gesture and thus the start of a possible operator control event can in principle be detectable by the at least one sensor element itself or by at least one other sensor element, possibly based on a different measuring principle and / or detecting another measured variable. For example, it can be capacitively detectable that a person has taken a certain position in relation to the vehicle and has extended a hand. In response to this, an ultrasonic sensor can then be activated, for example, which controls the adjustment of the adjustment part when the hand is subsequently moved in the direction of the closed position in cooperation with the control electronics. In principle, however, the beginning of the gesture controlling the closing of the adjustment part can also be detected by the at least one sensor element itself. This includes, for example, that via the at least one sensor element and the control electronics, a start gesture (contactless) can be detected as the start of the gesture controlling the closing of the adjustment part. This start gesture can in particular be different from the gesture controlling the closing. For example, one and the same sensor element can detect a person in the vicinity of the adjustment part with an outstretched hand and evaluate this as a start gesture. A subsequent sliding or swiveling gesture of the hand, which is carried out in front of the adjusting part to be closed, then serves to control the adjusting movement of the adjusting part.

A further aspect of the proposed solution provides an adjustment device in which an operating event for closing the adjustment part can be detected via at least one sensor element and control electronics of the adjustment device, in which a person removes the adjustment part located in an open position outside a grip area provided on the adjustment part touched. In this case, the control electronics are then set up to control a motor drive of the adjusting device in response to this for adjusting the adjusting part in the closing direction.

In the context of an adjusting device according to this aspect, it is consequently necessary to touch an adjusting part in order to trigger a closing of the adjusting part or at least to support a muscle-powered closing of the adjusting part by a motor. In this case, the actual contact with the adjustment part is recorded and, for example, a motor drive is not only activated when an adjustment movement triggered by muscle power has already started in the closing direction and this adjustment movement has been detected. In addition, in order to control the motor drive according to the proposed approach, it is not necessary for a user to actually act on a handle, for example on the outside handle of a vehicle door. Rather, a sensor-based detection of a touch of the adjustment part is provided precisely in an area outside of a grip area. In this way it can be sensed in the case of a vehicle door, for example, that a person grasps a door frame of an open vehicle door with one hand and exerts pressure in the closing direction. If a corresponding contact and possibly the exertion of a pressure force in the area of the door frame of the opened vehicle door is sensed, this triggers the motor drive of the adjusting device.

In one embodiment variant, a touch of the adjustment part with the palm of the hand can be detected via the at least one sensor element and the control electronics and can be assessed as an operating event for closing the adjustment part. In this context, it can also play a role, for example, that a sufficiently large section (outside of a grip area) is touched by the person and possibly gripped around. Touching a section that is larger in area is then assessed as an operating event, as a result of which incorrect triggering can be avoided.

Alternatively or additionally, a pressure force exerted by the person on the adjustment part can be detected via the at least one sensor element. In this case, the control electronics can be set up to control an adjustment movement of the adjustment part along the closing direction as a function of the level of the pressure force. For example, the control electronics implement a control logic that controls the speed of the adjustment movement when the adjustment part is closed depending on the level of the pressure force. This includes, for example, that the adjustment of the adjustment part is motor-assisted or motor-driven is more rapid when the pressure force is higher.

In one embodiment variant, the control electronics are set up to stop an adjustment of the adjustment part when the person no longer touches the adjustment part. The adjustment of the adjustment part is therefore only here sustained long as a person also maintains contact with the adjuster. Basically, in particular regardless of whether it is an adjustment device according to one or the other aspect explained above, the at least one sensor element can be a capacitive sensor, an ultrasonic sensor, an optical sensor, a tactile sensor, an infrared sensor, a pressure sensor, a piezo film and / or comprise a surface acoustic wave sensor. A capacitive sensor can e.g. B. additionally have a compensation electrode and / or an actively shielded shield electrode. In particular, time-of-flight measurements can be carried out using an optical sensor, for example, in order to detect an operator control event.

For example, an ultrasonic sensor is suitable both for contactless detection of a gesture that is carried out at a distance from the adjustment part to be adjusted and for detection of a touch of an adjustment part outside of a grip area. In the latter case it can be provided, for example, that an ultrasonic transducer is provided on the adjustment part, which excites vibrations. The vibration propagation changes depending on the force exerted on the adjustment part. If the excited vibrations in the adjustment part are accordingly detected by a receiver of the ultrasonic sensor, the signals received can be used to evaluate whether a person is attacking the adjustment part or not and thus the motor drive for closing the adjustment part should be controlled.

In principle, the adjusting part can be a vehicle door, for example.

In an embodiment variant with a vehicle door as the adjustment part, the sensor element is arranged, for example, on or behind a panel of the vehicle door, in particular on a panel provided on the outside of the vehicle door, or a frame of the vehicle door. For example, a corresponding sensor element can be arranged in the area of a seal on the frame side, possibly also in or behind a seal on the frame side.

A proposed adjusting device can be combined, for example, with at least one lighting element in one embodiment. If, for example, the approach of a person or the presence of a person in the vicinity of the vehicle is detected without contact, the at least one light element can be activated in order to visually signal to the person how a corresponding operating event is to be carried out for motor-assisted or motor-driven closing of the respective adjustment part . This includes, for example, the lighting of a corresponding area outside the handle area of the vehicle door, on which a contact by a person can be assessed as an operating event. This also includes, for example, the insertion of a hand movement on a display on the vehicle and in particular on the adjustment part.

A proposed adjusting device can not only be used to achieve a closing of an adjusting part that is improved in terms of convenience. For example, it is also conceivable that the proposed adjusting device (or an alternatively configured adjusting device) is provided to implement a motor-assisted or motor-driven adjustment of an adjustment part in an opening direction. In this case, for example, a gesture carried out with one hand in the opening direction is detected without contact and evaluated as an operating event for (further) opening the respective adjustment part. For example, a vehicle door can be pushed open or opened virtually by a person from the inside or outside without having to touch the vehicle door. Alternatively or in addition, the adjusting device can be set up to evaluate touching the adjusting part outside of a grip area as an operating event and thus an operating request to open the respective adjusting part.

Furthermore, an adjustment device with a motor drive and at least one sensor element can in principle also be set up to stop a currently executed adjustment movement of the adjustment part if, for example, a corresponding gesture or a touch of the adjustment part is detected.

In the context of the proposed solution, a method for the adjustment of an adjustment part is also proposed, which is adjustably mounted in a vehicle between a maximally open position and a completely closed position. A proposed method here comprises at least the following steps:

• - Detecting at least one operator event triggered by a person and
• - Activation of a motor drive in response to the operating event triggered by the person in order to adjust the adjustment part with the aid of the motor drive along a closing direction in the direction of a closed position of the adjustment part when the adjustment part is in an open position.

The proposed procedure also provides that

• - an operating event for closing the adjustment part (contactless) is detected, in which the person at a distance from the adjustment part in an open position performs a gesture with one hand in the direction of the closed position of the adjustment part, and the motor drive reacts to this Adjusting the adjusting part is controlled in the closing direction, or
• - An operating event for closing the adjustment part is detected, in which the person touches the adjustment part located in an open position outside a grip area provided on the adjustment part, and the motor drive is activated in response to this to adjust the adjustment part in the closing direction.

A proposed method can thus be carried out according to one or the other alternative by an adjusting device which is designed according to one or both aspects explained above. Advantages and features of design variants of a proposed adjusting device explained above and below therefore also apply to design variants of a proposed method and vice versa.

The attached figures exemplify possible variants of the proposed solution.

The 1 shows a detail with a view of a side vehicle door 1 a vehicle F. where the vehicle door 1 a body opening in a closed position O in the body K of the vehicle F. locks. The vehicle door 1 is about a pivot axis on the body K pivotally mounted to move along two opposite directions of adjustment Vo , Vs to be able to be pivoted between two end positions over a permissible adjustment range. In a first adjustment direction Vo is the vehicle door 1 pivotable in the direction of a maximum open position. Along a second, opposite adjustment direction Vs is the vehicle door 1 pivotable towards its closed position. Via one on the vehicle door 1 designated lock S. can the vehicle door 1 in their closed position with the body K be locked.

To generate a torque around the pivot axis of the vehicle door 1 - The present essentially parallel to a vertical axis of the vehicle F. runs - is in the area of a hinge of the vehicle door 1 an electric motor drive A. intended. About this electric motor drive A. , a driving force can be generated which results in a torque in the adjustment direction Vo or in the adjustment direction Vs leads.

The electric motor drive A. is with control electronics SE coupled based on sensor signals sa , sb and sc the electric motor drive A. heads to the vehicle door 1 motor-assisted or motor-driven to open or close. Motorized support from the electric motor drive A. This differs from an electric motor drive of the vehicle door 1 in that, when the respective adjustment movement is supported by an electric motor, it is assumed that a person is manually adjusting the vehicle door and consequently using muscle power on the vehicle door 1 for adjustment in one direction of adjustment Vo lying open position or in an adjustment direction Vs (Closing direction) exercising lying closed position. In contrast, if the vehicle door is driven 1 by the electric motor drive A. , it is generally assumed that a person himself does not exert any (relevant) force on the vehicle door 1 brings up.

The sensor signals sa , sb and sc to control the electric motor drive A. are presently generated by different sensors, for example to make a contactless gesture in the direction of the vehicle interior as an operating event for closing the opened vehicle door 1 to evaluate or to touch the vehicle door 1 to be recorded outside of a grip area and to be assessed as an operating event.

For example, in a sensor area away from a door handle 1.1 the vehicle door 1 an ultrasonic sensor or several ultrasonic sensors and / or at least one capacitive sensor can be provided in order to detect whether a person is in front of the vehicle door 1 standing, executes a gesture in the direction of the vehicle interior, which can be assessed as a virtual pressing of the vehicle door into the closed position. This is where the control electronics are, for example SE set up at a distance from the vehicle door which is in the open position 1 Gesture carried out by hand as an operating event for closing the vehicle door 1 to evaluate and the electromotive drive A. in such a way that the vehicle door 1 the gesture of the hand follows.

Are one or more sensors in sensor areas 1.2 or 1.3 on a window frame of the vehicle door 1 provided, this can be used, for example, to touch the vehicle door 1 detect. Then, for example, touches a person in the respective sensor area 1.2 or 1.3 the fully or partially open vehicle door 1 with the palm of the hand, this can be used as an operating event to control the electric motor drive A. be assessed, for example to close the vehicle door 1 to support. As long as a user with his hand against the corresponding sensor area 1.2 or 1.3 presses is the electric motor drive A. active and generates a torque in the adjustment direction Vs and thus the closing direction of the vehicle door 1 .

With the side views 2A and 2 B further areas are illustrated in which corresponding sensor elements can be provided. For example, at least one sensor can be on the outside or inside of the vehicle door 1 in the area of a frame near the B-pillar 12 , an inner or outer bezel 13 or 14th , in particular a panel in the area of a window frame of the vehicle door 1 , on a door skin 10 , an interior trim 11 or an upper part of a window frame 15th , in particular be arranged on or in a frame-side seal. Alternatively or in addition, especially for the detection of a closing of the vehicle door 1 executed gesture - at least one sensor element in an outside or inside grip area G1 or G2 the vehicle door 1 be arranged, for example in a corresponding recessed grip.

In the variant of the 3 is on or next to an outside grip area G1 a sensor 20th provided with which a larger sensor range 200 in the vicinity of the vehicle door 1 can be monitored contactless for the occurrence of an operator event. For example, it is the sensor 20th an ultrasonic sensor, in particular a MEMS ultrasonic sensor that is aligned with a slight incline to the horizontal. In the variant of the 3 is an example of an alignment 20a in the range from 1 ° to 10 ° (here about 10 °). The ultrasonic sensor can do this 20th a large area in front of the vehicle door 1 monitor almost optimally for the occurrence of an operator event. In particular, the ultrasonic sensor 20th the 1 designed as a 3D ultrasonic sensor and in the area of a bearing bracket of the handle area G1 be provided, in particular in a bearing bracket of the handle area G1 be integrated.

In the variant of the 4th are on the vehicle door 1 Ultrasonic sensors with microphones (especially MEMS microphones) in several places 21.1 and 21.2 arranged in the area of the upper part of the window frame and a panel near a B-pillar. In addition, as further parts of the ultrasonic sensors provided here or the corresponding ultrasonic sensor system are also sound transducers 22nd intended. You can use three or more MEMS microphones 21.1 and 21.2 as well as several transducers 22nd distributed over the vehicle door 1 improve the accuracy of the measurement. The MEMS microphones 21.1 and 21.2 are in the variant of the 4th for example arranged distributed along a door edge.

The illustrated arrangement of the 4th can be used, for example, via the sound transducer 22nd Vibrations in (sheet metal) components of the vehicle door 1 to stimulate. For example, the sound transducers 22nd glued to the corresponding components for this purpose. The sound propagation of the excited oscillations can be determined via the various spatially spaced MEMS microphones 21.1 and 21.2 be measured. Since the sound propagates through a to the vehicle door 1 If the force applied to the corresponding components changes, the sound propagation can be used to determine whether and, if so, with what force the components are acting. As a result, this can result in contact with the vehicle door 1 out of reach G1 determined and assessed as an operator event.

As an alternative or in addition to ultrasonic sensors and capacitive sensors, tactile sensors can also be used, for example in the frame-side seal of the vehicle door 1 , and / or one or more piezo foils in or behind a frame-side seal or a decorative panel of the vehicle door 1 are provided. As an alternative or in addition, surface acoustic wave sensors can also be used. Such surface acoustic wave sensors are for example for the excitation of acoustic surface waves on a Decorative strip and / or one of the panels 13 or 14th intended.

The 5 illustrates a possible sequence for a motor-driven closing of the vehicle door 1 where the vehicle door 1 follows a contactless gesture in the direction of the vehicle interior. The gesture is here from outside and in front of the vehicle door 1 standing person running.

In a first step, a person goes to the vehicle door 1 and is then activated by the vehicle door sensors 1 recognized as a user. The recognition as a user can in particular include that the person is authenticated as an authorized user, for example by establishing that the person is in the vehicle F. assigned authentication element, for example a transponder integrated in a vehicle key, carries. Alternatively, face recognition can be carried out. However, authentication can also be omitted for closing the vehicle door.

Was the person at the vehicle door 1 detected, an optical or acoustic feedback is given to signal the successful detection. The user now knows that he / she is making a gesture to close the vehicle door 1 can perform. The user now moves his hand in the direction of the vehicle door 1 and then performs a (sliding or swiveling) gesture in the direction of the vehicle interior, this is detected without contact by one or more of the sensors explained above. Via the control electronics SE then becomes the electric motor drive A. controlled in such a way that the vehicle door 1 follows the executed hand movement.

Will the vehicle door 1 sufficiently far in the direction of adjustment Vs adjusted in the direction of the closed position, the vehicle door moves 1 into a latch and is then automatically drawn. A lock signal can then be triggered by the user - for example also gesture-controlled or via a vehicle key. The lock is activated via this lock signal S. operated and the vehicle door 1 locked in their closed position. Here, the user receives before locking the lock S. another visual or acoustic feedback.

In the variant of the embodiment explained above 5 the gesture detection can for example be done by the mentioned ultrasonic sensors and / or by time-of-flight measurements (ToF measurements). Corresponding measuring methods and measuring principles can also be used in the embodiment variant of FIG 6th are used. Here, instead of one at a distance from the vehicle door 1 executed gesture an actual touch of the vehicle door 1 on one outside the reach G1 lying area of the vehicle door 1 detected as an operating event in order to control the electric motor drive A. to decide.

Even with the variant of the 6th it is provided in each case that the user is given visual and / or acoustic feedback about this when the sensor system has successfully detected an operating event. In the variant of the 6th becomes an operator request by touching the vehicle door 1 , for example in the area of the frame 12 and / or in the area of the diaphragm 13 or 14th detected. It is assumed here that a user opens the vehicle door 1 from an open position in the adjustment direction Vs wants to press and therefore with his hand the vehicle door 1 touches on one of the mentioned areas, in particular includes. The corresponding contact then generates a supporting torque by the electric motor drive A. triggered. If necessary, a door arrester is used beforehand to release the vehicle door 1 actuates the vehicle door 1 holds previously locked in an at least partially open position.
