Description

Technical Field

[0001] The invention relates to a method for operating a motor-driven flap assembly of a motor vehicle according to the preamble of claim 1, a control assembly for a motor-driven flap assembly of a motor vehicle according to the preamble of claim 13, and a flap assembly of a motor vehicle according to claim 14. Background Art

[0002] The flap assembly in question has a flap that can be adjusted in a motor-driven manner. The flap can be any closing element of a motor vehicle. This includes a rear flap, a tailgate, a front hood, in particular a hood, a door, in particular a side door or a rear door, etc. The flap is arranged on the motor vehicle body in a pivotable or longitudinally displaceable manner.

[0003] In the known method (DE 10 2017 129 151 A1) on which the present invention is based, the operation of the flap is specified by a predefined operator action, which can be formed by a foot movement of the operator. The manipulation detected as a valid operator action causes the motor-driven flap assembly to be actuated, so that the operator can open or close the flap in particular contactlessly.

[0004] In order to increase the comfort when operating the flap, it is advantageous to keep the operating actions to be performed by the operator simple. However, the challenge here is to ensure the detection of the operator actions with high reliability while preventing the motor-driven adjustments from being unintentionally triggered due to movements that are incorrectly evaluated as valid operator actions. Summary of the invention

[0005] The problem underlying the present invention is to specify a method of the generic type which further improves the reliability of the recognition of operator actions when using radar sensors.

[0006] This problem is solved by the characterizing features of claim 1 .

[0007] The invention is based on the recognition that undesired triggering of motor-driven adjustments can occur by movements of an operator who performs them while standing still on the flap assembly. In particular, leg movements of an operator who is seated on the motor vehicle, for example on a support beam of the rear flap, can lead to erroneous triggering. The basic consideration that the operator's standing still is detected based on the sensor value of the radar sensor and measures to suppress erroneous triggering are important.

[0008] It is proposed in detail that the detected sensor values ​​are checked by means of a control component according to a predetermined stay criterion, which represents the operator's stay at the flap component, and based on the fulfillment of the stay criterion, the control component is occupied in an inhibition mode, in which the operator action criterion is changed compared to the normal mode of the control component.

[0009] Signal strength, for example the strength of a received radar signal, has proven to be a particularly reliable criterion for detecting the presence of an operator, so that in the preferred embodiment according to claim 2 the signal strength criterion is used for triggering the suppression mode.

[0010] A further advantageous variant of the stationary criterion is proposed in claim 3. According to the distance value criterion, sensor values ​​representing short distances can be taken into account in particular and, for example, static objects at greater distances can be screened out when detecting a stationary operator. Preferably, a speed value criterion is also used, whereby substantially stationary operators can be easily detected.

[0011] Furthermore, according to the embodiment according to claim 4 , time dependencies in the sensor values, in particular the exceeding of the dwell time, are taken into account for particularly reliable detection of the dwell.

[0012] Particularly preferably, according to claims 5 to 7, a target tracking routine for the radar target is also performed by means of the control module, wherein the radar target trajectory is acquired. Thus, erroneous triggering of the suppression mode, for example due to other static objects, can also be ruled out with high reliability. Preferably, a check is performed to determine whether the radar target first passes through an approach phase (claim 6).

[0013] Preferred embodiments according to claims 8 and 9 relate to the interruption or termination of the suppression mode. The termination can be effected according to claim 8 by canceling the stop state and / or according to claim 8 in a time-controlled manner.

[0014] Preferably, after the end of the suppression mode, a compensation of the sensor values ​​is also performed, in particular based on a time lapse, which is reflected in claim 9. The time lapse can be attributed to static objects, such as accessories, parts, etc., being placed in the detection range of the radar sensor and remaining there. Background signals generated by such objects in subsequent measurements can be avoided by the compensation.

[0015] In a particularly preferred embodiment according to claim 10 , the suppression mode can also be terminated by the aforementioned target tracking routine, wherein a renewed distance of the radar target is checked.

[0016] In the suppression mode, a more robust operator action criterion can be used to check the operator action, which is the subject of claim 11. In this context, in the suppression mode, it is also possible to trigger the motor-driven adjustment by an operator action, while simultaneously avoiding false triggering due to a stationary operator.

[0017] According to the further teaching according to claim 13 having independent significance, protection is claimed for a control arrangement for a motor-driven flap arrangement of a motor vehicle.

[0018] It is important here that the control assembly checks the detected sensor value according to a predetermined stop criterion, which represents the operator's stop at the flap assembly, and that the control assembly adopts a suppression mode in which the operator action criterion is changed compared to the normal mode of the control assembly in accordance with the satisfaction of the stop criterion. Reference can be made to all embodiments of the proposed method.

[0019] According to the further teaching according to claim 14, which likewise has independent significance, a flap assembly of a motor vehicle is claimed for carrying out the proposed method. Reference is made to all the embodiments relating to the proposed method and the proposed control assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The invention is explained in more detail below with reference to the accompanying drawings which illustrate only an exemplary embodiment. In the drawings:

[0021] Figure 1 The present invention shows a perspective view of the rear region of a motor vehicle having a flap arrangement and a control arrangement for carrying out the proposed method. DETAILED DESCRIPTION

[0022] The proposed method relates to the operation of a motor-driven flap assembly 1 of a motor vehicle 2 . A control assembly 3 serves to actuate a motor-driven drive assembly 4 associated with the flap assembly 1 .

[0023] In the illustrated and in this respect preferred embodiment, the drive assembly 4 is provided for transferring a flap 5 of the flap assembly 1 from a closed position (not shown) into an open position (shown). It is likewise possible to provide for the flap 5 to be transferred from an open position into a closed position. In principle, the drive assembly 4 can also bring about other motor-driven adjustment functions of the flap assembly 1, such as unlocking and / or opening a motor vehicle lock associated with the flap 5. For possible configurations of the flap 5, reference is made to the embodiments described at the beginning, wherein the flap 5 is here arranged according to the Figure 1 The preferred design of is shown as a rear flap by way of example.

[0024] An electronic radar sensor 6 is coupled to the control arrangement 3, wherein sensor values ​​relating to objects outside the motor vehicle 2 are detected by means of the radar sensor 6. In this context, the focus is on detecting sensor values ​​relating to an operator 7 of the motor vehicle 2 and operator actions performed by the operator 7 outside the motor vehicle 2. An "operator action" can be understood here generally to mean an action of the operator 7, in particular a movement pattern of a body part of the operator 7, such as an operator gesture.

[0025] Here and preferably, the radar sensor 6 has a sensor unit 8 with a corresponding antenna assembly, which is preferably designed with one or more antenna arrays. The antenna arrays are arranged in particular in predetermined angular positions and positions relative to each other in order to enable angular resolution of the radar signal. Here and preferably, the radar sensor 6 implements continuous, further preferably frequency-modulated distance and direction measurement, for example as an FMCW radar sensor. The radar sensor 6 is preferably designed to operate with radar radiation in a frequency band around 24 GHz and / or 77 GHz.

[0026] The sensor values ​​represent the position of objects outside the motor vehicle 2. The sensor values ​​include, for example, the detected object, mainly distance information and direction information between the operator 7 and the motor vehicle 2. Furthermore, the sensor values ​​also include speed information, such as based on a Doppler speed value of the object.

[0027] The sensor unit 8 is preferably arranged on the flap assembly 1 so that the operator 7 can perform an operator action to trigger a motor-driven adjustment on the flap assembly 1. Here and preferably, the sensor unit 8 is arranged on the rear bumper 9, wherein the operator 7 triggers the adjustment with a predefined operator action, such as a foot movement in front of the bumper 9, preferably a kicking movement.

[0028] The detected sensor values ​​are checked for compliance with a predetermined operator action criterion by means of the control assembly 3, wherein the operator action detected by the sensor values ​​is rejected or assessed as a valid operator action depending on the result of the check. Upon detection of a valid operator action, the drive assembly 4 is actuated by means of the control assembly 3 for motor-driven adjustment of the flap assembly 1.

[0029] In the monitoring process, the sensor values ​​are checked here by means of the control component 3 for fulfillment of operator action criteria. The operator action criteria can relate to predetermined features of the operator action, such as the position, velocity, acceleration, etc. of a body part. For example, the detected sensor values ​​can be checked for agreement with predetermined features and a similarity or operator action probability can be determined in which the sensor values ​​represent an operator action with the corresponding features. Based on the operator action probability, it is checked whether the operator action can be evaluated as valid with respect to the predetermined criteria.

[0030] For example, the (single) operator action probability is weighted by a predetermined coefficient and incorporated into the total probability. In particular, a probability threshold value can be predetermined for the total probability. For a total probability below the probability threshold value, no actuation of the drive assembly 4 is caused. On the other hand, for a total probability greater than or equal to the probability threshold value, the drive assembly 4 is actuated by means of the control assembly 3. A single operator action criterion can also be specified as an operator action criterion that is sufficient or necessary for the actuation and / or the operator action probability can also be checked separately. Other configurations of the operator action criterion are conceivable.

[0031] It is now important to check the detected sensor values ​​with the aid of the control component 3 according to a predetermined stay criterion, which represents the stay of the operator 7 at the flap component 1, and to occupy a suppression mode with the aid of the control component 3 according to the fulfillment of the stay criterion, in which the operator action criterion is changed compared to the normal mode of the control component 3.

[0032] In many cases, the effective operator action is preceded by a temporally preceding approach of the operator 7. For example, the operator 7 approaches the rear flap and after a short pause performs an operator gesture, such as a kicking movement, in order to open the rear flap.

[0033] However, a longer stay of the operator 7 in the region of the flap assembly 1, which initially occurs without an operator action, is usually not related to the intended operation, so that there is a risk of erroneous triggering. Figure 1 , a movement such as the swinging of the legs can be mistakenly recognized as a valid operator action. A similar situation is a long-term continuous activity of the operator 7 in the area of ​​the flap assembly 1, such as maintenance, repair, cleaning and rearranging of items in the load compartment of the motor vehicle 2. Such situations have in common that the movements of the operator 7 can be mistakenly interpreted as valid operator actions.

[0034] The suppression mode according to the proposed method is therefore intended to prevent possible erroneous triggering when the operator 7 is stationary, which is achieved by adapting the operator action criteria. "Stay" is generally understood to be a behavior of the operator 7 that indicates the operator 7's stationary state at the flap assembly 1 without an actuation desire and is characterized in particular by a duration that is too long for an actuation desire.

[0035] In contrast, the normal mode refers to the operating mode of the control arrangement 3 which is assumed when the operator 7 is not present, for example an operating mode with lower requirements for operator actions to be evaluated as valid and thus with a high probability of recognizing operator actions.

[0036] Here and preferably, it is provided that the stop criterion comprises a signal strength criterion of the detected sensor value, preferably the signal strength criterion relates to the fulfillment of at least one signal strength threshold value by the signal strength of the sensor value, in particular the signal strength of the spatial integration of the spatially resolved sensor value.

[0037] The signal strength criterion represents one or more intensities of the radar signal received by the radar sensor 6. Preferably, an energy equivalent is calculated from the sensor value, for example from the amplitude and phase of the received radar signal, as the signal strength, which is input into the signal strength criterion. In a simple design, the signal strength can be compared with a signal strength threshold value.

[0038] In the case of spatially resolved sensor values ​​that can be detected, for example, by the aforementioned use of an antenna array or a plurality of sensor units 8, the signal strength criterion can relate to the integrated signal strength. This can be understood to mean that the signal strengths of different detection directions and / or different detection ranges are linked to one another, in particular added to one another. It is also conceivable to weight different detection directions and / or different detection ranges and to screen out specific detection directions and / or detection ranges in the evaluation of the signal strength criterion.

[0039] Furthermore, it is preferably provided here that the stop criterion comprises a distance value criterion of the detected sensor value, preferably the distance value criterion relates to a distance value comprised in the sensor value falling below at least one distance threshold value.

[0040] With regard to the distance criterion, objects closer to the flap assembly 1 are preferably weighted more highly than objects further away from the flap assembly 1. This approach is based on the knowledge that the operator 7 is at a small distance from the motor vehicle 2 when he is standing still without any intention to operate. In contrast, in many cases, detected objects at a greater distance represent static objects or, for example, an operator 7 who hesitates when approaching with the intention to operate and then continues to approach.

[0041] The distance threshold value makes it possible, for example, to take into account in the stop criterion only objects detected in the sensor values ​​that are below a maximum distance.

[0042] In a further refinement, it is provided that the stop criterion comprises a speed value criterion of the detected sensor value, preferably the speed value criterion relates to a speed value, in particular a Doppler value, contained in the sensor value falling below at least one speed threshold value.

[0043] Speed ​​values, such as Doppler values, can hereby indicate with high reliability that at least a part of the body of operator 7 is essentially stationary on motor vehicle 2 . This situation can also indicate that operator 7 is merely stationary, but does not intend to operate.

[0044] Here, it is also possible to determine a velocity value, such as a Doppler value, from the radar signal without detecting a temporal correlation. However, it is particularly preferably provided that the stop criterion relates to the temporal correlation of the detected sensor values.

[0045] The stop criterion can be defined at least in part by satisfying at least one subcriterion of the stop criterion, in particular the signal strength criterion, the distance value criterion and / or the speed value criterion, for a predetermined stop duration. The stop duration here means that after the stop duration has elapsed, generally no manipulation is desired. If the operator 7 remains in the region of the flap assembly 1 for the stop duration, for example, without substantially moving, an erroneous triggering can be prevented by the suppression mode.

[0046] In this case, it is not mandatory that at least one subcriterion is continuously met for the dwell duration. Rather, the sum of the durations in which at least one subcriterion is met can also be taken into account by measuring the time interval. However, it is further preferably provided that the dwell criterion is at least partially defined in that at least one subcriterion of the dwell criterion is continuously met for the dwell duration. “Continuously” can be understood here to mean that the detected sensor value continuously and without deviations meets at least one subcriterion for the dwell duration.

[0047] Furthermore, it is preferably provided here that a time-dependent association of the detected sensor values ​​with the radar target is carried out by means of the control component 3 in a target tracking routine and a radar target track is determined for the radar target and the stop criterion relates to the radar target track.

[0048] In this case, radar targets are preferably identified in the sensor values, in particular based on the intensity of the reflected radar waves and preferably based on exceeding a predefined intensity threshold. In particular, a plurality of radar targets detected in the sensor values ​​are combined into a cluster target according to a cluster model. By tracking the radar targets over time, a radar target trajectory can be obtained, which represents the time correlation of the position of the radar target.

[0049] The radar target track can be used to detect the stop of the operator 7. It is also provided here and preferably that the stop criterion is at least partially defined in that the radar target passes through a predetermined approach phase relative to the flap assembly 1 according to the radar target track and temporally occupies a predetermined stationary phase after the approach phase.

[0050] The approach phase is preferably defined at least in part by the approach of the radar target from a predetermined first distance to a predetermined second distance that is reduced relative to the first distance. Since static objects also cause static radar target tracks, it is possible to exclude with high reliability that static objects lead to the triggering of the suppression mode. The target tracking routine and the checking of the approach phase more precisely ensure that the radar target in the stationary phase is a movable object and is with high reliability an operator 7.

[0051] The stationary phase can generally be formed by a time period during which the radar target remains in the region of the flap assembly 1, wherein reference is made to the above-described embodiments regarding the stationary criterion. It is also provided here and preferably that the stationary criterion, in particular the stationary phase, is at least partially defined in such a way that the sensor values ​​associated with the radar target follow a signal strength criterion, a distance value criterion and / or a speed value criterion, preferably the stationary phase is defined at least partially in such a way that the sensor values ​​associated with the radar target follow a signal strength criterion, a distance value criterion and / or a speed value criterion for a predetermined stationary duration.

[0052] In a further, likewise preferred embodiment, provision is made for the detected sensor values ​​to be checked by means of the control arrangement 3 in the suppression mode for fulfillment of a termination criterion, preferably for non-fulfillment of a stop criterion, and for the suppression mode to be terminated as a result of the fulfillment of the termination criterion.

[0053] If the dwell criterion is defined, for example, based on exceeding a signal strength threshold value during the dwell duration, the sensor value is further checked in the suppression mode with respect to exceeding the signal strength threshold value. If the exceeding disappears, in particular for a predetermined minimum duration, the suppression mode can be terminated. Preferably, the control component 3 then assumes the normal mode again.

[0054] In a further preferred embodiment, provision is made for the control arrangement 3 to check the expiration of a time-dependent termination criterion, in particular a predetermined termination duration, in the suppression mode and to terminate the suppression mode in response to the fulfillment of the termination criterion. If the suppression mode is triggered unintentionally by a static object, for example an accessory mounted on the motor vehicle 2, such as a trailer coupling 10, etc., then, for example, a continuous continuation of the suppression mode is prevented. Accordingly, the suppression duration can be selected to be relatively long, for example in the form of the order of several hours.

[0055] It is further preferably provided that, upon fulfillment of a time-dependent termination criterion, a standstill compensation value of the detected sensor value is determined by means of control component 3 and an operator action criterion is checked by means of control component 3 with respect to the sensor value compensated by the standstill compensation value.

[0056] The sensor value is compensated by the quiescent compensation value, whereby the sensor value is at least partially cleared of temporally varying background signals, such as those caused, for example, by static objects, such as the trailer coupling 10. In a simple case, the quiescent compensation value represents, to a certain extent, a “null signal” of the sensor value in the absence of an operator action and is subtracted from the sensor value for compensation.

[0057] In a further refinement, it is provided that the radar target track is checked by means of the control arrangement 3 in the suppression mode with respect to the passage of the distance phase and that the suppression mode is terminated as a function of the passage of the distance phase.

[0058] The target tracking routine mentioned can therefore also be used to terminate the suppression mode. If the radar target, which has triggered the suppression mode, for example by passing through an approach phase and a stationary phase, leaves the area of ​​the flap assembly 1 again, the stationary state can be considered to have been cancelled. The distance phase can be defined in particular in the opposite way to the approach phase, in that the radar target moves from a predetermined first distance to a second distance that is greater than the predetermined first distance. By means of target tracking, it is also ensured here that radar signals of other objects in the vicinity of the operator 7 do not lead to an undesired termination of the suppression mode.

[0059] Furthermore, it is preferably provided here that in the suppression mode the operator action criterion is changed in such a way that the above-mentioned probability threshold for assessing a valid operator action is reduced compared to the normal mode.

[0060] Therefore, stricter requirements are placed on the implementation of effective operator actions. For example, the operator action criteria are changed in such a way that the swinging motion of the sitting operator 7 can be further distinguished from the kicking motion used for triggering.

[0061] At least one parameter of the operator action probability for determining the operator action criterion can also be changed compared to the normal mode, for example by modifying the aforementioned features of a valid operator action, changing the coefficients for taking into account the individual probabilities, etc.

[0062] At least one parameter can relate to the direction of movement of the operator's action. In this regard, the swinging movement of the sitting operator 7 can also be further divided from the kicking movement.

[0063] In another preferred embodiment, at least one parameter can relate to the position of the operator's action. Figure 1 If the suppression mode is triggered by an operator 7 sitting on the support beam as in the example above, the sensor values ​​for the detection range in which the operator 7 is located can be suppressed and in particular masked out with respect to the evaluation of the operator's actions. If another person 11 performs an operating action in another detection range, this can nevertheless still be checked for validity.

[0064] In a further embodiment, it is provided that in the suppression mode the operator action criterion is changed in such a way that an actuation for carrying out a motor-driven adjustment is prevented.

[0065] As a result, the triggering of the motor-driven adjustment by an operator action is deactivated, so that unintentional triggering in a stationary state is completely prevented.

[0066] In addition, a control component 3 for a motor-driven flap assembly 1 of a motor vehicle 2 is proposed, wherein the control component 3 is set up for controlling a motor-driven drive component 4 assigned to the flap assembly 1 and for coupling to a radar sensor 6, wherein the radar sensor 6 detects sensor values ​​related to an operator 7 and operator actions performed by the operator 7 outside the motor vehicle 2, wherein the control component 3 checks the detected sensor values ​​with respect to satisfying predetermined operator action criteria, wherein the operator action detected by the sensor values ​​is discarded or evaluated as a valid operator action depending on the result of the check, and wherein the control component 3 controls the drive component 4 based on the detection of the valid operator action for motor-driven adjustment of the flap assembly 1.

[0067] It is important here that the control component 3 checks the detected sensor value according to a predetermined stay criterion, which represents the stay of the operator 7 at the flap component 1, and the control component 3 occupies an inhibition mode according to the fulfillment of the stay criterion, in which the operator action criterion is changed compared to the normal mode of the control component 3.

[0068] Reference is made to all embodiments of the method according to the proposal.

[0069] Furthermore, a flap assembly 1 of a motor vehicle 2 is proposed for carrying out the proposed method. The flap assembly 1 preferably has a control assembly 3 according to the proposed method, a radar sensor 6 and a motor-driven drive assembly 4 .
