Abstract

The invention relates to a method for actuating a motorized closure element assembly (1) of a motor vehicle (2). The closure element assembly (1) has a closure element (3), a drive assembly (4) paired with the closure element (3), a control assembly (5), and a sensor assembly (6). The sensor measurement values of the sensor assembly (6) are monitored by means of the control assembly (5) in order to determine whether a triggering operating situation is occurring which is defined by at least one operating situation condition. If the triggering operating situation is detected by means of the control assembly (5), an actuation of the closure element assembly (1) is triggered. An operating situation condition of the triggering operation situation is defined as the operator (B) guiding an object (G), in particular carrying an object, such that the operator (B) and the carried object (G) are detected by means of the control assembly (5), and the actuation of the closure element assembly (1) is triggered based thereon.

Description

Method for controlling a motor-driven closure element arrangement of a motor vehicle

The invention relates to a method for controlling a motor locking element arrangement of a motor vehicle according to the preamble of claim 1 and to a control system for a motorized closure element arrangement according to the preamble of claim 15.

Motorized closure element arrangements have largely prevailed in recent years in the context of increasing the comfort of motor vehicles. The closure elements of such closure element arrangements may be, for example, doors, in particular side doors, flaps, in particular tailgates, trunk lids, engine hoods, load compartment floors or the like of a motor vehicle. The closing element of the closure element arrangement is often associated with a drive arrangement by means of which the closure element can be opened and closed by a motor An example of this is provided by DE 10 2014 101 661 A1, which relates to a method for controlling a motorized tailgate arrangement of a motor vehicle.

The above method, from which the invention proceeds, relates to the detection of a predetermined foot movement of the operator. It enables the reduction of error detections by detecting not only the moving leg of the operator, but also the resting leg of the operator. As a result of the detection of two body parts, the result is a particularly high level of security.

In another known method for controlling a motor tailgate assembly (DE 10 2013 010 994 AI), the detection reliability is increased by detecting a movement of a body part of the upper body of the operator. The known methods have proven in practice especially for the case that a predetermined operator movement, in particular an operator gesture, is used to trigger the activation of the respective closure element arrangement. A challenge arises when the operator movements provided for triggering the control are not as pronounced as a foot movement, or when no operator movement is provided for triggering the control at all. Especially in the latter case can be implemented with great effort with the known methods, a high detection reliability.

The invention is based on the problem to provide a method for controlling a motor-driven closure element arrangement of a motor vehicle, with which the detection reliability is increased with the acquisition of an operating situation with little effort.

The above problem is solved in a method according to the preamble of claim 1 by the features of the characterizing part of claim 1.

The basic idea of the invention is that an operator who carries an object with him, in particular, wears it, wants to place it in the trunk before he sits down in the motor vehicle and optionally drives off. Thus, if it is detected whether the operator carries an object with him, this can lead to an increased detection security of the operating situation monitoring, since the operator would most likely want to store the entrained object in the trunk.

Specifically, it is generally proposed that an operating situation condition of the triggering operating situation is defined by the fact that the operator carries an object with him, in particular carries, and that by means of the control arrangement, the operator and the entrained object are detected and that in dependence from which the activation of the closure element arrangement is triggered.

With the proposed solution, therefore, the detection security can be increased by detecting that the operator with an object leads itself. Especially in this situation, for example, when it comes to a heavy beer crate, it is advantageous if a triggering operating situation is detected quickly and safely, preferably without an eventual multiple moving of body parts. In the sense of increased detection reliability as to whether a triggering operating situation exists, further operating conditions, in particular the movement of body parts, can continue to be provided. The possibly additional provision of the operating condition condition, whether the operator carries an object, then increases the detection s safety of the operating situation.

Furthermore, this operating situation condition can also enable a faster detection of a triggering operating situation. This is particularly advantageous when the operator carries a heavy object, such as a beer crate, with him. Just then he would no longer like to dwell in the region of the closure element before the opening of the closure element is carried out. In this respect, in such a situation, a shortened detection of the triggering operating situation may be achieved, and thus made more pleasant for the operator, than if he is staying in the area of the closure element without an entrained object. In this case, the predetermined time for persistence for an operation situation condition may be reduced, for example.

According to a particularly preferred embodiment of the method, the control arrangement detects objects in the sensor measured values of the sensor arrangement, separates them and assigns them to an object class in each case. The object class is preferably an object class from the object classes "operator" and "object", possibly additionally from the object class "environment".

In a further embodiment of the invention, it is proposed that the operator and / or the carried object be localized on the basis of the sensor measured values, in particular relative to the sensor arrangement. Here, the relative arrangement of the object and the operator is preferably determined. This allows conclusions to be drawn as to whether the item is carried by the operator. According to claim 3 it is proposed that the control arrangement tracks movements of the operator and / or the entrained object and detects the relative movements of the operator and the object carrying the object by the operator. If these have a similar speed and / or directions of movement, this is a strong indication for an operator to carry along. Accordingly, for example, at similar speeds and / or directions of movement of the control arrangement, a tracking of the object to be detected by the operator. Additionally or alternatively, as described in claim 4, the control arrangement can detect body parts of the operator and, by detecting a connection between the object and a body part of the operator, in particular an arm and / or a hand of the operator, with the object carrying the object to capture. This also results in a secure determination of entrainment of an object by the operator.

According to claim 5, the sensor measured values of the sensor arrangement contain SD information, on which preferably the detection of the operator and / or the entrained object is based at least in part. Also, the detection of whether the operator carries an object can be detected or determined on the basis of the 3D information. For this purpose, relative movements of the operator and / or object can be evaluated by means of the 3D information and / or the relative arrangement of operator and object can optionally be evaluated over time.

According to claim 6, the sensor arrangement comprises a camera-based sensor element, in particular a time-of-flight camera and / or a 3D camera system with two camera sensors spaced apart from one another. These can provide the previously described 3D information.

According to claim 7, it is proposed for further development of the invention that the triggering operating situation comprises a logical link, in particular an AND link and / or an OR link between two or more operating situation conditions. According to claim 8, the control arrangement detects the arrangement of the body parts of the operator to each other - posture. Then, an operating situation condition of the triggering operating situation can be defined by the fact that the operator has assumed a predetermined posture. The body posture can possibly be used to draw conclusions about the object, such as its size and / or weight and thus whether the operator would like to put the article in the trunk or not and whether or not an operating situation condition is fulfilled. An operating situation condition may also be, for example, according to claim 9, that the operator a body part in a predefined manner relative to other body parts - body part movement - is moved, preferably that the body part movement is a foot movement and / or a nod and / or a wave.

For example, according to claim 10, an operating situation condition may be that the operator removes an object from the loading space of the motor vehicle and moves away from the motor vehicle. According to claim 11, a further operating condition condition of the triggering operating situation is defined in that the alignment of at least a body part of the operator is within a predetermined allowable alignment range about the vertical that is detected by the sensor arrangement, if the orientation of the at least a body part of the operator to the vertical lies in the permitted alignment region and, depending on this, the activation of the closure element arrangement is triggered. In this regard, reference is made to the German application DE 10 2016 108 702. The features and advantages described on this operating condition condition in the above patent application are fully incorporated by reference.

In the development according to claim 12, a second sensor element for detecting a second operating situation condition of the triggering operating situation is proposed to further increase the detection s safety. An operating situation triggering the operating situation can also be defined according to claim 13 in that the position of the operator within a predetermined time window does not change or only in a certain position range.

In accordance with a further operating situation condition of the triggering operating situation, a proximity to the closure element and / or vehicle can be defined and the presence of the operator in this proximity area can be a triggering operating situation for the operating situation.

Furthermore, an operating situation condition of the triggering operating situation can be defined by the fact that the operator moves out of a predetermined proximity area associated with the closure element and / or motor vehicle and then moves back into the proximity area.

According to a further teaching according to claim 15, which has independent significance, a control system for a motor-driven closure element arrangement of a motor vehicle is claimed, which in particular serves to carry out the above proposed method.

Essential according to the further teaching is that the control system has a control arrangement and a sensor arrangement, which interact to implement the proposed method with each other. In this respect, reference may be made to all comments on the proposed procedure.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. In the drawing shows

1 shows the rear area of a motor vehicle with a motor-driven closure element arrangement, and with a proposed control system associated with the closure element in a side view,

2 shows the rear area of the motor vehicle according to FIG. 1 with two operating situations, each in a view from above, wherein the operator as an object in a) carries a box and b) carries a bag,

Fig. 3 shows an operator carrying an article in a) a box and b) a bag.

The proposed method is used to control a motor-driven closure element arrangement 1 of a motor vehicle 2, which is equipped with a closure element 3, a control arrangement 5 and a sensor arrangement 6. Here and preferably, the closure element arrangement 1 is also equipped with a drive arrangement 4 assigned to the closure element 3 for the motorized adjustment of the closure element 3.

The closure element 3 may be all types of closure elements of a motor vehicle 2, as has been explained in the introductory part of the description. Here and preferably, the closure element 3 is the tailgate of a motor vehicle 2. All versions of a tailgate apply to all other types of closure elements accordingly.

In a first preferred embodiment, the term "activation of the motor-driven closure element arrangement" means that the closure element 3 is adjusted by means of the drive arrangement 4. The actuation of the closure element arrangement 1 is therefore always connected to a drive of the drive arrangement 4, not shown In detail, the closure element 3 of the closure element arrangement 1 is wholly or partially moved between a fully closed position (shown in solid lines in FIG. 1) and a fully open position (shown in dashed line in FIG. 1) by means of the drive arrangement In principle, provision can also be made for activation of the motor-driven closure element arrangement 1 to effect only pressing-on of the closure element 3, so that an engagement gap between the closure element 3 and the motor vehicle body is achieved tsteht, in which the operator B engage and can make the further adjustment of the closure element 3 manually. The term "activation of the motor-driven closure element arrangement" means in a second preferred embodiment that a motor vehicle locking system assigned to the closure element arrangement 1, not shown here, in particular at least one associated motor vehicle lock, is adjusted by a motor of the lock state, for example between the lock states "locked" and "unlocked", so that an opening of the motor vehicle lock is possible depending on the lock state Finally, the adjustment of the motor vehicle lock can be an above pressing of the closure element 3 in the above sense.

The term "motor" in the present case includes any adjustability with any kind, in particular electrical, actuator.

The sensor measured values of the sensor arrangement 6 are then monitored by means of the control arrangement 5 as to whether a triggering operating situation exists. The control arrangement 5 is thus coupled in terms of control technology to the sensor arrangement 6, so that the generation of corresponding sensor measured values of the sensor arrangement 6 can be triggered by means of the control arrangement 5. Depending on the application, the sensor arrangement 6 can comprise imaging sensors, in particular camera-based sensor elements 8, distance sensors 9, or the like.

Here and preferably, the sensor arrangement 6 has a camera-based sensor element 8, in particular a time-of-flight camera and / or an SD camera system with two camera sensors which are objected to one another. 3D camera systems are usually referred to as a stereo camera.

Furthermore, the sensor arrangement 6 can comprise a radar sensor, with which body parts of the operator B, including their orientation, can be easily detected. As distance sensors 9 for the sensor assembly 6 capacitive sensors have proven. In that regard, reference may be made to the German application DE 10 2014 101 661 AI of 11 February 2014, which dates back to the Applicant and which is the subject of the present application.

As indicated above, the sensor arrangement 6 serves to monitor the sensor measured values of the sensor arrangement 6 as to whether there is a triggering operating situation. Such an operating situation is, as proposed, defined by at least one operating situation condition. Such an operating situation can basically affect static parameters such as the current position, but also dynamic parameters such as the movement of at least one body part of the operator B. When detecting such a defined operating situation, a corresponding control of the closure element arrangement 1 is carried out by means of the control arrangement 5.

The detection of a triggering operating situation above, when the closure element 3 is completely closed, preferably results in the closure element 3 being adjusted by means of the drive arrangement 4 in the opening direction, preferably in the fully open position. Conversely, the detection of a triggering operating situation with the closure element 3 fully open preferably leads to the closure element 3 being adjusted by means of the drive arrangement 4 in the closing direction, preferably in the completely closed position. Essential for the proposed solution is a special definition of an operating situation. An operating situation condition of the triggering operating situation is accordingly defined by the fact that the operator B carries an object G with him, in particular carries, as shown in FIG. 3, and that by means of the control arrangement 5 the operator B and the entrained object G are detected and that, depending on the triggering of the closure element assembly 1 is triggered.

The detection of the entrainment of an object G by the operator represents a particularly simple operating situation condition. This operating situation condition can be the only operating situation condition for a triggering operation. be situation. In particular, if this operating situation condition is used linked to already other operating situation conditions, the detection reliability can be increased and / or the time for detecting a triggering operating situation can be reduced by this additional operating situation.

The control arrangement 5 preferably acquires objects 7 in the sensor measured values of the sensor arrangement 6, separates them, and assigns them to an object class. The object class is preferably taken from the group of object classes "operator" and "object". Preferably, the object class "environment" is also assigned to this group of object classes, Preferably, objects associated with the "environment", such as a tree U in Fig. 3, are not considered in detail in the evaluation of the sensor measured values the operator B entrains an object G results from the fact that the control arrangement 5 tracks movements of the operator B and / or the entrained object G and detects the relative movements of the operator B and the object G, the entrainment of the object G by the operator B. If the object G and the operator B have similar directions of movement and / or speeds, or, if the object moves within a predetermined short range NB of the operator B, it can be concluded that this is carried by the operator B. This is preferably done by means of the or the camera-based sensor elements 8 detected.

Below a similar speed, a speed difference of less than 10%, in particular less than 5%, is considered here and preferably. The direction of movement is preferably similar when the direction s vector of the directions of movement of the object G and the operator B fall apart less than 20 °, preferably less than 10 °, more preferably less than 5 °.

Additionally or alternatively, the control arrangement 5, in particular by means of the camera-based or sensor elements, body parts of the operator B detected and by detecting a connection between the object G and a body part of the operator B, in particular an arm and / or a hand of the operator B, with the object G detect the entrainment of the object. Preferably, it is also detected whether the operator carries the entrained object in front of him, as shown for example in FIGS. 2a) and 3a), or whether he carries the object next to him, as shown in FIG. 2b). and 3b). Here and preferably, the control arrangement 5 is designed to detect a head and / or a face and / or upper body and / or limbs, in particular arms and / or legs optionally including the hand or foot, of the operator B as body parts and / or to recognize. Additionally or alternatively, a hand and / or a foot can be detected as a body part. Furthermore, the control arrangement 5 here and preferably is further configured to classify the size and / or the weight of the object G on the basis of the sensor measured values. Preferably, an operating situation condition may include the classification by size and / or weight. For example, the control arrangement 5 can determine the size of the object G from the sensor measured values absolutely and / or in relation to the operator B. This is preferably possible with a time-of-flight camera to be assigned to the sensor arrangement 6 and / or a 3D camera system with two camera sensors, in particular a stereo camera, which are objected to one another.

Furthermore, the control arrangement 5 can preferably detect the arrangement of the body parts of the operator B relative to one another - posture. From the posture, the control arrangement 5 here and preferably draw conclusions about the weight of the object G.

If, for example, the operator B carries only a small, light object G, for example a small bag, with him, the likelihood that he would like to place this article G in the trunk is less than if he had a large and bulky object G, for example a box, with you. In this respect, here and preferably with a smaller object G at least one operating situation condition formed differently and / or an operating condition condition additionally linked with a triggering operating situation, as in a large object. Further possible operating conditions and their connection will be described in more detail below.

Additionally or alternatively, it has been proven, as already explained above, if the sensor measured values of the sensor arrangement contain 3D information. This is particularly advantageous for the determination of the size and / or the weight. Here, the detection of the operator B and / or the entrained object G is preferably based at least in part on the 3D information. Camera-based sensor elements 6, in particular, have proven to be suitable for this purpose, such as, for example, a time-of-flight camera and / or a 3D camera system with two camera sensors which are objected to one another. Time-of-flight cameras usually illuminate a scene by means of a light pulse, and measure for preferably each pixel the time it takes the light to reach an object and back again. Since the time required is directly proportional to the distance, the removal of the object imaged thereon can thus be provided by means of a camera, preferably for each pixel.

Here and preferably, the control arrangement 5 has a neural network for evaluating the sensor measured values. The use of a neural network, in particular for image analysis, has long been known to the person skilled in the art. Here and preferably, the neural network determines whether a detected operator B carries a detected object G with him / her and / or an operating situation exists.

In addition, a capacitive distance sensor 9 may be provided, which preferably extends over the width of the motor vehicle 2. With the capacitive distance sensor 9, an operating gesture, for example the foot movement indicated in FIG. 1, can be detected well.

Finally, a transmitting / receiving unit 10 is provided, which in the present case can also be associated with the sensor arrangement 5. The transmitting / receiving unit 10 is used for communication with a portable identification unit 11 such as a an electronic key or an ID card with an integrated RFID chip. By means of the transmitting / receiving unit 10, not only the operator B can be authenticated, but also the distance of the operator B, who carries the portable identification unit 11, to the transmitting / receiving unit 10. This distance can basically be defined in the above sense as the operating situation of the triggering operating situation. It can also serve the purpose of determining whether the operator is in the proximity area NF assigned to the closure element 3 and / or motor vehicle 2. As indicated above, a triggering operating situation may include a plurality of operating conditions. Within the definition of the operating situation, these operating situation conditions are preferably logically linked to one another, in particular AND-linked and / or OR-linked. For example, the control arrangement 5, the arrangement of the body parts of the operator to each other - posture - capture and the Bediensituations- condition of the triggering operating situation be defined by the fact that the operator B has taken a predetermined posture. This may, for example, be a bow in front of the closure element 3. The detection of the posture takes place here and preferably by means of a camera-based sensor element and / or a radar sensor.

Another operating condition condition may relate to the foot movement of the operator B shown in FIG. 1, which may be detected in particular by the capacitive distance sensor 9. Accordingly, an operating situation condition of the triggering operating situation is preferably defined by the operator B moving a body part in a predefined manner relative to other body parts - body part movement. This body part movement may be the previously mentioned foot movement and / or a nodding and / or a wave. The body part movement or the body part movement sequence described below is also detected here and preferably by means of the camera-based sensor element.

Another example of an operating situation condition of the triggering operating situation can be a body part movement sequence, that is to say in particular be defined by successive Köperteilbewegungen several body parts. This can be defined, for example, in that the operator B removes an object G from the loading space of the motor vehicle 2 and moves away from the motor vehicle 2.

With a camera-based sensor element 8, however, it is likewise readily possible to determine not only the position but also an orientation of the operator B, in particular of his body parts, and / or of the object G. A particularly advantageous operating situation condition of the triggering operating situation is here and preferably defined by the fact that the alignment of at least a body part of the operator B is about the vertical V in a predetermined allowable alignment area A that is detected by the sensor assembly 6, whether the orientation of the at least one body part of the operator B is about the vertical V in the allowed alignment area and depending on the triggering of the closure element assembly 1 is triggered.

This operating condition condition is described in detail in the German patent application DE 10 2016 108 702. The body parts of the operator B, which may lie around the vertical V in the allowed alignment area A, are here and preferably the upper body of the operator B and / or the head of the operator B and / or an eye of the operator B. Also in this regard, the above referenced patent application and this made in this respect the subject of this application. Another operating condition condition of the triggering operating situation is preferably defined by the fact that the position of the operator B does not change within a predetermined time window or only in a predetermined position range. This can be, for example, the persistence for a predetermined time, for example four seconds, in the proximity area NF and / or the alignment area A associated with the closure element 3 and / or the motor vehicle 2.

Additionally or alternatively, an operating situation condition of the triggering operating situation can be defined by the fact that an operator B in the proximity area NF assigned to the closure element 3 and / or motor vehicle 2 applies. is send. The short-range area NF is here and preferably a predetermined short-range area of the closure element 3 and / or motor vehicle 2.

Another operating situation can be defined by the fact that the operator B moves out of a predetermined proximity area NF assigned to the closure element 3 and / or motor vehicle 2 and / or, in particular subsequently, moves into the proximity area NF.

Other operating conditions, which in turn may be logically linked, are conceivable.

According to a further teaching, which has independent significance, a control system for a motor-driven closure element arrangement of a motor vehicle 2 as such is claimed, which is specially set up for carrying out the above-mentioned proposed method. In that regard, reference may be made to all the submissions concerning the proposal.

The proposed control system 12 has a control arrangement 5 and a sensor arrangement 6, as shown in FIG.

The sensor measured values of the sensor arrangement 6 are then monitored by means of the control arrangement 5 as to whether a triggering operating situation explained above exists, and wherein the control arrangement 5 triggers activation of the closure element arrangement 1 upon detection of the triggering operating situation. Incidentally, the operation of the control system 12 corresponds to an implementation of the above proposed method.
