Description

[0001] Method for operating a motorized flap arrangement of a motor vehicle

[0002] The present invention relates to a method for operating a motorized flap arrangement of a motor vehicle according to the preamble of claim 1, a control arrangement for a motorized flap arrangement of a motor vehicle according to the preamble of claim 13 and a flap arrangement of a motor vehicle according to claim 14.

[0003] The flap assembly in question has a motor-adjustable flap. The flap can be any closure element of a motor vehicle. This includes tailgates, trunk lids, front hoods, especially engine hoods, doors, especially side or rear doors, or the like. The flap can be mounted on the vehicle body in a pivotable or longitudinally displaceable manner.

[0004] In the known method (DE 102017 129 151 A1), on which the invention is based, the flap is operated via a predefined operator action, which can be a foot movement by the operator. An actuation detected as a valid operator action triggers the activation of the motorized flap assembly, allowing the operator to open or close the flap, in particular without contact.

[0005] To increase comfort when operating the flap, it is advantageous to keep the operator's actuation simple. However, it is challenging to ensure the reliable detection of operator actions while simultaneously preventing unwanted triggering of the motorized adjustment due to movements that are incorrectly classified as valid operator actions.

[0006] The invention is based on the problem of providing a generic method that further improves the detection reliability of operator actions when using radar sensors. The above problem is solved by the features of the characterizing part of claim 1.

[0007] The invention is based on the realization that undesired triggering of the motorized adjustment can occur due to movements made by the operator while standing at the flap assembly. In particular, leg movements of an operator sitting at the vehicle, for example, on the loading edge of a tailgate, can lead to false triggering. The fundamental idea is to detect the operator's position based on the radar sensor values ​​and to initiate measures to suppress false triggering.

[0008] In detail, it is proposed that the recorded sensor values ​​are checked by means of the control arrangement for a predetermined dwell criterion, which represents a dwell of the operator at the flap arrangement, and that upon fulfillment of the dwell criterion, a suppression mode is adopted by means of the control arrangement, in which the operator action criteria are modified compared to a normal mode of the control arrangement.

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

[0010] Further advantageous variants of the dwell criterion are specified in claim 3. Using a distance value criterion, the sensor values ​​representative of short distances can be used, and, for example, static objects at a greater distance can be masked out when detecting a lingering operator. The use of a speed value criterion is also preferred, allowing a substantially stationary operator to be easily detected. For particularly reliable detection of lingering, the consideration of a time dependency, in particular the exceeding of a dwell time, in the sensor values ​​according to the embodiment of claim 4 also serves to ensure particularly reliable detection of lingering.

[0011] Particularly preferred is also the implementation of a radar target tracking routine using the control arrangement according to claims 5 to 7, wherein a radar target trajectory is determined. Consequently, erroneous triggering of the suppression mode, for example, due to other static objects, can be ruled out with a high degree of certainty. For this purpose, it is preferably checked whether the radar target first undergoes an approach phase (claim 6).

[0012] The preferred embodiments according to claims 8 and 9 relate to aborting or terminating the suppression mode. Termination can be performed according to claim 8 by canceling the dwell state and / or in a time-controlled manner.

[0013] It is also preferred to perform compensation of sensor values ​​after the suppression mode has ended, in particular due to a time lapse, as recited in claim 9. The time lapse may be due to static objects such as attachments, accessories, or the like being placed and remaining in the detection range of the radar sensor. Compensation can prevent a background signal generated by such objects in subsequent measurements.

[0014] Likewise, in the particularly preferred embodiment according to claim 10, the termination of the suppression mode can be implemented by the target tracking routine mentioned, wherein a renewed removal of the radar target is checked.

[0015] In the suppression mode, more robust operator action criteria can be used to check the operator action, which is the subject of claim 11. This makes it possible to continue to trigger the motorized adjustment via an operator action in the suppression mode, while simultaneously avoiding false triggering by the operator remaining in the position.

[0016] According to a further teaching according to claim 13, which has independent significance, a control arrangement for a motorized flap arrangement of a motor vehicle is claimed.

[0017] It is essential that the control system checks the recorded sensor values ​​for a predefined dwell criterion, which represents the operator remaining at the flap assembly. Upon fulfillment of the dwell criterion, the control system enters a suppression mode in which the operator action criteria are modified compared to a normal mode of the control system. Reference is made to all explanations of the proposed method.

[0018] According to a further teaching according to claim 14, which also has independent significance, a flap arrangement of a motor vehicle for implementing the proposed method is claimed. Reference is made to all statements regarding the proposed method and the proposed control arrangement.

[0019] In the following, the invention is explained in more detail with reference to a drawing which merely illustrates exemplary embodiments. In the drawing,

[0020] Fig. 1 is a perspective view of a rear area of ​​a motor vehicle with a flap arrangement and a control arrangement for carrying out the proposed method.

[0021] The proposed method relates to the operation of a motorized flap arrangement 1 of a motor vehicle 2. A control arrangement 3 serves to control a motorized drive arrangement 4 assigned to the flap arrangement 1.

[0022] In the illustrated and, in this respect, preferred embodiment, the drive arrangement 4 is provided for transferring the flap 5 of the flap arrangement 1 from a closed position (not shown) to the open position shown. Transferring the flap 5 from an open position to a closed position can also be provided. In principle, the drive arrangement 4 can also effect other motorized adjustment functions of the flap arrangement 1, for example unlocking and / or opening a motor vehicle lock associated with the flap 5. For possible embodiments of the flap 5, reference is made to the introductory statements, wherein the flap 5 is shown here as an example in the form of a tailgate according to the preferred embodiment of Fig. 1.

[0023] An electronic radar sensor 6 is coupled to the control arrangement 3, wherein the radar sensor 6 detects sensor values ​​relating to objects outside the motor vehicle 2. The focus here is on detecting sensor values ​​relating to an operator 7 of the motor vehicle 2 and an operator action performed by the operator 7 outside the motor vehicle 2. An operator action is generally understood to mean an action by the operator 7, in particular a movement pattern of a body part of the operator 7, such as an operator gesture.

[0024] Here, and preferably, the radar sensor 6 comprises sensor units 8 with respective antenna arrangements, which are preferably configured with one or more antenna arrays. The antenna arrays are arranged, in particular, at a predetermined angular position relative to one another to enable angular resolution of the radar signals. Here, and preferably, the radar sensor 6 implements a continuous, more preferably frequency-modulated, distance and direction measurement, for example, as an FMCW radar sensor. The radar sensor 6 is preferably configured for operation with radar radiation in the frequency band around 24 GHz and / or 77 GHz.

[0025] The sensor values ​​are representative of the position of objects outside the motor vehicle 2. For example, the sensor values ​​contain distance information and directional information between the detected object, including the operator 7, and the motor vehicle 2. Furthermore, the sensor values ​​also contain speed information, for example based on Doppler speed values, of the object. The sensor units 8 are preferably provided on the flap arrangement 1 so that the operator 7 can perform the operator action to trigger the motorized adjustment of the flap arrangement 1. Here and preferably, the sensor units 8 are arranged on the rear bumper 9, with the operator 7 triggering the adjustment with a predefined operator action such as a foot movement, preferably a kicking movement, in front of the bumper 9.

[0026] The recorded sensor values ​​are checked by control arrangement 3 for compliance with predefined operator action criteria. Depending on the result of the check, the operator action recorded via the sensor values ​​is either rejected or qualified as a valid operator action. Upon detection of a valid operator action, the drive arrangement 4 is controlled by control arrangement 3 for motorized adjustment of the flap arrangement 1.

[0027] In a monitoring run, the sensor values ​​are checked by the control arrangement 3 for compliance with the operator action criteria. The operator action criteria can relate to predetermined characteristics of the operator action, for example, the position, speed, acceleration of the body part, or the like. The recorded sensor values ​​can, for example, be checked for compliance with the specified characteristics, and a degree of similarity or an operator action probability can be determined that the sensor values ​​are representative of an operator action with the respective characteristic. Based on the operator action probabilities, a check is carried out using predetermined criteria to determine whether the operator action can be qualified as valid.

[0028] For example, the (individual) operator action probabilities are weighted using predefined factors and incorporated into an overall probability. In particular, a probability threshold can be specified for the overall probability. For an overall probability below the probability threshold, no activation of the drive arrangement 4 results. For an overall probability greater than or equal to the probability threshold, however, the drive arrangement 4 is activated by the control arrangement 3. Individual operator action criteria can also be defined as operator action criteria sufficient or necessary for activation, and / or operator action probabilities can also be checked individually. Further configurations of the operator action criteria are conceivable.

[0029] It is now essential that the recorded sensor values ​​are checked by means of the control arrangement 3 for a predetermined dwell criterion, which represents a dwell of the operator 7 at the flap arrangement 1, and that upon fulfillment of the dwell criterion, a suppression mode is adopted by means of the control arrangement 3, in which the operator action criteria are modified compared to a normal mode of the control arrangement 3.

[0030] In many cases, a valid operator action is preceded by an immediate temporal approach by operator 7. For example, operator 7 approaches the tailgate and, after briefly stopping, performs an operator gesture such as a kicking motion to open the tailgate.

[0031] However, an extended period of time spent by the operator 7 in the area of ​​the flap arrangement 1, which initially occurs without any operator action, is generally not associated with an intention to actuate it, so that there is a risk of false activation. If, for example, the operator 7 is sitting on a loading sill assigned to the flap arrangement 1, as shown in Fig. 1, movements such as swinging the legs could be erroneously recognized as a valid operator action. Similar situations to this are longer-lasting activities of the operator 7 in the area of ​​the flap arrangement 1, such as maintenance, repairs, cleaning of the motor vehicle 2 and rearranging objects in the cargo space of the motor vehicle 2. What such situations have in common is that a movement of the operator 7 could be erroneously interpreted as a valid operator action.

[0032] The suppression mode of the proposed method is therefore aimed at preventing a possible false triggering when an operator 7 remains at the flap assembly 1. This is achieved by adapting the operator action criteria. A "remaining" is generally understood to mean a behavior of the operator 7 that is indicative of the operator 7 remaining at the flap assembly 1 without any intention to actuate it, and which is characterized in particular by a period of time that is too long for an intention to actuate it.

[0033] The normal mode, on the other hand, represents an operating mode of the control arrangement 3 which is adopted without the operator 7 remaining, for example an operating mode with lower requirements for qualification as a valid operator action and consequently with a high probability of recognition of operator actions.

[0034] Here and preferably it is provided that the dwell criterion contains a signal strength criterion of the detected sensor values, preferably that the signal strength criterion relates to the fulfillment of at least one signal strength threshold value by a signal strength of the sensor values, in particular a spatially integrated signal strength of spatially resolved sensor values.

[0035] The signal strength criterion is representative of one or more intensities of the radar signals received by radar sensor 6. Preferably, an energy equivalent is calculated as signal strength from the sensor values, for example, from the magnitude and phase of the received radar signals, which is then input into the signal strength criterion. In a simple embodiment, the signal strength can be compared with a signal strength threshold.

[0036] For spatially resolved sensor values, which can be detected, for example, through the aforementioned use of antenna arrays or multiple sensor units 8, the signal strength criterion can refer to an integrated signal strength. This means that signal strengths from different detection directions and / or different detection ranges are correlated with one another, in particular, added together. It is also conceivable to weight different detection directions and / or different detection ranges, as well as to mask out certain detection directions and / or detection ranges when assessing the signal strength criterion.

[0037] Furthermore, it is preferably provided here that the dwell criterion contains a distance value criterion of the recorded sensor values, preferably that the distance value criterion relates to the falling below at least one distance threshold value by distance values ​​contained in the sensor values.

[0038] With the distance criterion, objects closer to the flap assembly 1 are given a higher weighting than objects further away from the flap assembly 1. This approach is based on the realization that the operator 7, when standing still without intending to actuate the flap assembly, is at a short distance from the motor vehicle 2. In contrast, detected objects at a greater distance often represent static objects or, for example, an operator 7 who hesitates when approaching with the intention of actuating the flap assembly and then continues approaching.

[0039] For example, the distance threshold ensures that only objects detected in the sensor values ​​below a maximum distance are taken into account in the dwell criterion.

[0040] In a further embodiment, it is provided that the dwell criterion contains a speed value criterion of the detected sensor values, preferably that the speed value criterion relates to the falling below at least one speed threshold value by speed values ​​contained in the sensor values, in particular Doppler values.

[0041] The speed values, such as the Doppler values, can indicate with a high degree of certainty that at least part of the body of operator 7 remains essentially motionless on the motor vehicle 2. This circumstance can also indicate that operator 7 is merely remaining stationary, but not intending to act.

[0042] Speed ​​values ​​such as Doppler values ​​can also be determined based on the radar signals without detecting a time dependency. However, it is particularly preferred that the dwell criterion relates to a time dependency of the detected sensor values.

[0043] The dwell criterion can be defined at least partially by at least one sub-criterion of the dwell criterion, in particular the addressed signal strength criterion, the distance value criterion, and / or the speed value criterion, being met for a predetermined dwell time period. The dwell time period is representative of the fact that, after its expiration, there is generally no actuation request. If, for example, the operator 7 remains essentially motionless in the area of ​​the flap arrangement 1 for the dwell time period, false activation can be prevented via the suppression mode.

[0044] The at least one sub-criterion does not necessarily have to be met continuously throughout the dwell time. Rather, the sum of the time periods in which the at least one sub-criterion is met can also be taken into account over a measurement time interval. However, it is further preferred that the dwell time criterion is at least partially defined by at least one sub-criterion of the dwell time criterion being met continuously for the dwell time period. "Continuously" is understood to mean that the recorded sensor values ​​continuously and without deviation meet the at least one sub-criterion throughout the dwell time period.

[0045] Furthermore, it is preferably provided here that by means of the control arrangement 3 in a target tracking routine a time-dependent association of detected sensor values ​​to a radar target is carried out and a radar target trajectory is determined for the radar target, and that the dwell criterion relates to the radar target trajectory.

[0046] 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 whether a predetermined intensity threshold is exceeded. In particular, several radar targets detected in the sensor values ​​are combined into a cluster target according to a cluster model. By tracking the radar target over time, a radar target trajectory can be determined, which represents the time-dependence of the radar target's position.

[0047] The radar target trajectory can be used to detect the presence of an operator 7. Furthermore, it is preferably provided here that the presence criterion is defined at least partially by the radar target passing through a predetermined approach phase to the flap arrangement 1 according to the radar target trajectory and entering a predetermined rest phase following the approach phase.

[0048] The approach phase is preferably defined at least partially by the radar target approaching from a predetermined first distance to a predetermined second distance, which is reduced from the first distance. Consequently, it can be ruled out with high certainty that static objects will trigger the suppression mode, since static objects also result in a static radar target trajectory. Rather, the target tracking routine and the approach phase check ensure that the radar target in the resting phase is a moving object and, with high certainty, an operator 7.

[0049] The rest phase can generally be formed by a period of time during which the radar target remains in the region of the flap arrangement 1, reference being made to the above explanations regarding the rest criterion. Furthermore, it is preferably provided here that the rest criterion, in particular the rest phase, is defined at least partially by the sensor values ​​associated with the radar target meeting the signal strength criterion, the distance value criterion, and / or the speed value criterion, preferably that the rest phase is defined at least partially by the sensor values ​​associated with the radar target meeting the signal strength criterion, the distance value criterion, and / or the speed value criterion for a predetermined rest period.

[0050] In a further, likewise preferred embodiment, it is provided that by means of the control arrangement 3 in the suppression mode, the detected sensor values ​​are checked for fulfillment of a termination criterion, preferably a failure to fulfill the dwell criterion, and that the suppression mode is terminated upon fulfillment of the termination criterion.

[0051] For example, if the dwell criterion is defined based on exceeding a signal strength threshold during a dwell time, the sensor values ​​continue to be checked in suppression mode for exceeding the signal strength threshold. If the threshold is not exceeded, particularly for a predetermined minimum period, the suppression mode can be terminated. Preferably, the control arrangement 3 then returns to normal mode.

[0052] In a further preferred embodiment, it is provided that a time-dependent termination criterion, in particular the expiration of a predetermined suppression period, is checked by means of the control arrangement 3 in the suppression mode, and that the suppression mode is terminated upon fulfillment of the termination criterion. This prevents, for example, a continuous continuation of the suppression mode if the suppression mode was undesirably triggered by static objects, for example, attachments attached to the motor vehicle 2 such as a trailer hitch 10 or the like. Accordingly, the suppression period can be selected to be comparatively long, for example, on the order of several hours.

[0053] Furthermore, it is preferably provided that, upon fulfillment of the time-dependent termination criterion, rest compensation values ​​of the detected sensor values ​​are determined by means of the control arrangement 3, and that, by means of the control arrangement 3, the operator action criteria are checked on sensor values ​​compensated via the rest compensation values.

[0054] The sensor values ​​are compensated here by the rest compensation values, which at least partially cleans the sensor values ​​of time-varying background signals, such as those caused by static objects such as the trailer hitch 10. In a simple case, the rest compensation values ​​represent the "empty signal" of the sensor values ​​in the absence of operator action and are subtracted from the sensor values ​​for compensation.

[0055] In a further embodiment, it is provided that by means of the control arrangement 3 in the suppression mode, the radar target trajectory is checked for passing through a distance phase and the suppression mode is ended upon passing through the distance phase.

[0056] Consequently, the aforementioned target tracking routine can also be used to terminate the suppression mode. If the radar target, which, for example, led to the triggering of the suppression mode by passing through an approach phase and a rest phase, leaves the area of ​​the flap arrangement 1 again, it can be assumed that the dwell state has been canceled. The distance phase can be achieved - in particular inversely to the approach phase - by the radar target moving from a predetermined first distance to a predetermined second distance that is greater than the first distance. Target tracking also ensures that radar signals from other objects besides the operator 7 do not lead to an undesired termination of the suppression mode.

[0057] Furthermore, it is preferably provided here that the operator action criteria in the suppression mode are modified in such a way that the already mentioned probability threshold for qualification as a valid operator action is reduced compared to the normal mode.

[0058] Consequently, stricter requirements are placed on the execution of a valid operator action. For example, the operator action criteria are modified so that a pendulum movement of a seated operator 7 can be further distinguished from a kicking movement to trigger the trigger.

[0059] Likewise, at least one parameter for determining the operator action probability of an operator action criterion can be modified compared to the normal mode. For example, the aforementioned characteristics of a valid operator action are modified, the factors for considering the individual probability are modified, or the like.

[0060] The at least one parameter can relate to a direction of movement of the operator action. This can also further differentiate the pendulum movement of a seated operator 7 from a kicking movement.

[0061] In a further preferred embodiment, the at least one parameter can relate to the position of the operator action. For example, if the suppression mode is triggered by an operator 7 sitting on the loading edge, as shown in Fig. 1, the sensor values ​​for the detection area in which the operator 7 is located can be suppressed and, in particular, hidden in the evaluation of the operator action. If another person 11 performs an actuation in a different detection area, this can still be checked for validity.

[0062] In a further embodiment, it is provided that the operator action criteria in the suppression mode are modified in such a way that control for motorized adjustment is prevented.

[0063] This deactivates the triggering of the motorized adjustment by the operator action, so that accidental triggering in the dwell state is completely prevented.

[0064] Also proposed is a control arrangement 3 for a motorized flap arrangement 1 of a motor vehicle 2, wherein the control arrangement 3 is designed to control a motorized drive arrangement 4 assigned to the flap arrangement 1 and to be coupled to a radar sensor 6, wherein the radar sensor 6 detects sensor values ​​relating to an operator 7 and an operator action performed by the operator 7 outside the motor vehicle 2, wherein the control arrangement 3 checks the detected sensor values ​​for compliance with predetermined operator action criteria, wherein, depending on the result of the check, the operator action detected via the sensor values ​​is rejected or qualified as a valid operator action, and wherein the control arrangement 3, upon detecting a valid operator action, controls the drive arrangement 4 for the motorized adjustment of the flap arrangement 1.

[0065] What is essential here is that the control arrangement 3 checks the recorded sensor values ​​for a predetermined dwell criterion, which represents a dwell of the operator 7 at the flap arrangement 1, and that the control arrangement 3, upon fulfillment of the dwell criterion, assumes a suppression mode in which the operator action criteria are modified compared to a normal mode of the control arrangement 3.

[0066] Reference is made to all statements regarding the proposed method. Furthermore, a flap assembly 1 of a motor vehicle 2 for implementing the proposed method is proposed. The flap assembly 1 preferably comprises the proposed control assembly 3, the radar sensor 6, and the motor drive assembly 4.

[0067] Reference may be made to all statements concerning the proposed procedure and the proposed tax order 3.
