Definitions
- the 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 performing such a method according to claim 15 and a flap arrangement with such a control arrangement according to claim 16.
- the motorized adjustment of hinged flaps of motor vehicles is an important comfort function today. It is important for user acceptance that secondary functions such as holding the flap securely in intermediate positions are satisfactorily solved.
- the tailgate is regularly lowered due to gravity from an unenergized intermediate position if the associated drive arrangement is designed to be driven back. This undesired adjustment movement can be prevented, for example, by a mechanical brake.
- the known method (DE 10 2012 018 990 A1), from which the invention is based, makes use of such a mechanical brake.
- the disadvantage here is the high mechanical complexity.
- control-related measures for holding a window pane in intermediate positions are known (DE 10 2004 017 110 A1, EP 1 645 710 A1), in which a control loop directed towards holding the window pane is provided.
- window panes can be part of the re de standing flap arrangement by being taken up by the flap and moved accordingly with the flap.
- the requirements for motorized adjustment and the holding of window panes are fundamentally different than for free-swinging flaps.
- the force relationships prevailing for the adjustment and holding change with each adjustment of the flap.
- the invention is based on the problem of designing and developing the known method in such a way that the outlay for holding the flap in de-energized intermediate positions is reduced.
- the fundamental consideration is that when a flap deflection, in particular due to gravity, occurs from an de-energized intermediate position of the flap, it is initially detected is whether there is a predetermined flap deflection that requires holding. If this is the case, a hold control circuit is activated, which leads to a corresponding actuation of the drive arrangement which can be driven back.
- intermediate position is to be understood broadly here and encompasses any position of the flap in which the flap has been pivoted out of the closed position, that is to say the fully closed position of the flap fully open position of the flap
- de-energized intermediate position means that the flap is in the intermediate position while the drive arrangement is de-energized.
- the de-energized intermediate position is preferably a static intermediate position in which the flap is stationary.
- drive arrangement that can be driven back means that the drive train of the drive arrangement that is not energized can be driven back by manually adjusting the flap. A necessary prerequisite for this is the non-self-locking design of the transmission components of the drive train of the drive arrangement.
- a control routine in particular a gravity-related predetermined flap deflection
- a holding routine is triggered upon detection of the predetermined flap deflection, in which the drive arrangement is activated by a corresponding current supply
- Holding flap position is regulated in a holding control loop. So this corresponds to a position control of the flap.
- the flap can be held in intermediate positions without additional mechanical measures being required. Due to the fact that a holding control loop with appropriate feedback is provided, any environmental conditions, in particular a possible slope length of the motor vehicle or the like, can be reacted to automatically. The above-mentioned changing force relationships on the flap no longer play any significant role.
- the drive arrangement can comprise a single drive with a drive motor or two drives, each with a drive motor. In the latter case, it can be provided in a variant that only one of the two drives is regulated to the holding flap position. This is appropriate if the system friction to be explained is correspondingly large (claim 2).
- the holding flap position can in principle be the intermediate position from which the flap is deflected. For this it is necessary that the intermediate position has been saved in terms of control technology when it is taken. Alternatively, however, it can also be provided that the holding flap position is the deflected flap position. This is appropriate since it will regularly be sufficient to hold the deflected position of the flap (claim 3).
- Claim 5 relates to two preferred variants for the detection of the flap deflection, namely the monitoring of the generator voltage of a drive motor of the drive arrangement and the monitoring of the sensor signal of a sensor assigned to the drive arrangement. Monitoring the generator voltage is particularly advantageous when there is no sensor for detecting a flap movement
- the manipulated variable of the holding control loop is the electrical voltage and / or the electrical current of at least one drive motor of the drive arrangement.
- the amount of the relevant electrical variable depends on is varied according to control strategy.
- a variation of the pulse width and pulse frequency can alternatively be provided, provided that the electrical variables in question are pulse width-modulated variables.
- the electrical voltage or the electrical current can be used as a manipulated variable in a simple control-technical manner.
- the further preferred configurations according to claims 7 and 8 relate to the implementation of an operating mode and a standby mode for the control arrangement. While the entire range of functions of the drive arrangement is preferably available in the operating mode, only minimal functions are available in the standby mode. The advantage associated with this is that the power consumption in standby mode can be kept extremely low. It is preferably the case that the standby mode is set to fulfill a standby condition,
- the also preferred configurations according to claims 9 and 10 relate to the consideration that the amount of the restoring force generated by the drive arrangement for holding the flap can be determined and taken into account in the proposed hall control loop. For example, it is assumed according to claim 10 that exceeding the restoring force above a predetermined actuation threshold is very likely due to a manual action by the user on the flap. Accordingly, it is provided in an alternative that the holding routine is exited in this case. Alternatively or additionally, it can be provided according to claim 10 Depending on the direction of the restoring force, an adjustment routine such as a closing adjustment or an opening distribution is triggered. The holding routine is thus used to a certain extent twice, namely on the one hand for the original holding of the flap and on the other hand for the detection of a possible manual force exerted by the user on the flap
- an actuation sensor is assigned to the flap according to claim 1 1. This further reduces the likelihood of the user holding the head undesirably.
- the further preferred embodiment according to claim 12 relates to the equipment of the drive arrangement with an active side in the form of a motor drive and with a passive side in the form of a spring unit.
- the spring unit is a gas pressure spring
- signs of aging are to be expected, which are manifested in a reduction in the spring force of the spring unit.
- This undesired reduction in the spring force can be easily detected in the holding routine, since the motor drive, depending on the aging condition of the spring unit, has to introduce more or less drive force, usually against gravity, into the flap in order to hold the flap in the holding flap position to keep.
- an error routine is carried out, which can be configured differently. It is thus possible to react early to an age-related reduction in the spring force of the spring unit, for example by replacing the spring unit.
- the occurrence of the predetermined reduction in the spring force of the spring unit is preferably detected by checking the manipulated variable in the holding control loop.
- an error criterion is further preferably defined, which represents the predetermined reduction in the spring force of the spring unit to a certain extent.
- This check of the manipulated variable can be easily implemented since the holding control loop is provided for holding the flap anyway.
- the control arrangement which is set up for carrying out the proposed method is claimed as such. This is preferably achieved by running a software on the control arrangement which is used to implement the monitoring routine and the holding routine. In this respect, reference may be made to all explanations regarding the first-mentioned teaching
- the flap is pivotable about a horizontal pivot axis, so that the flap weight preferably acts in the closing direction of the flap.
- the system friction according to claim 18 is preferably designed such that the flap is held in at least one de-energized intermediate position by means of the static system friction, but, preferably, the sliding system friction that occurs after overcoming the static system friction to hold the flap not enough.
- the flap is designed to be self-retaining thanks to the system friction, provided that the flap is in a static, that is to say unmoved, state. However, as soon as external influences such as a gust of wind, slamming a door, loading the motor vehicle, folding down a load compartment floor or the like.
- FIG. 1 shows the rear area of a motor vehicle with a proposed flap arrangement
- Fig. 2 shows the drive arrangement of the flap arrangement according to Fig. F in a schematic representation
- FIG. 3 shows a proposed method for operating the flap arrangement according to FIG. 1.
- the proposed method is directed to the operation of a motorized flap arrangement 1 of a motor vehicle, the flap arrangement 1 having a flap 4 which can be pivoted relative to a motor vehicle body 3.
- the flap 4 is pivotable about a pivot axis 4a, the position of which can be fixed or variable relative to the motor vehicle body 3.
- the term "flap” is to be understood broadly here.
- swiveling tailgates, boot lids, bonnets, bonnets it also includes swiveling side doors.
- the flap axis 4a of the flap 4 is oriented essentially horizontally in the illustrated and in this respect preferred exemplary embodiment, so that the weight of the flap 4 acts at least over an adjustment range of the flap 4 in its closing direction.
- the flap arrangement 1 has a retractable drive arrangement 5 for the motorized adjustment of the flap 4.
- the flap arrangement 1 also has a control arrangement 6 for controlling the drive arrangement 5.
- the control arrangement 6 can be assigned exclusively to the drive arrangement 5, which corresponds to a decentralized control concept. In principle, however, it can also be provided that the control arrangement 6 is at least partially assigned to a higher-level motor vehicle control.
- control arrangement 6 detects a predetermined Kiappenauslenkung, here and preferably gravity-related, from a non-energized intermediate position of the flap 4 in a monitoring routine 7. It is also essential that a holding routine 8 is triggered upon detection of the predetermined flap deflection, in which the drive arrangement 5 is regulated to a holding flap position in a holding control loop.
- This two-stage procedure via the monitoring routine and via the holding routine downstream of the monitoring routine allows, on the one hand, a modular construction in terms of control technology, in which the monitoring routine 7 in a first control module, in particular in a first software module, and the holding routine 8 in a second control module, in particular can be accommodated in a second software module.
- the monitoring routine 7 can run in a power-saving standby mode.
- the proposed solution leads to a secure holding of the flap 4 in intermediate positions without the need for an additional mechanical brake.
- the drive arrangement 5 has a first drive 9 and a second drive 10 which engage on opposite sides of the flap 4.
- the drives 9, 10 are spindle drives.
- all other types of drives can be used here.
- both drives 9, 10 are regulated to the holding flap position.
- only one of the two drives 9, 10, here the drive 9 shown on the left in FIG. 2 is regulated to the holding flap position.
- the holding flap position is defined as the intermediate position from which the predetermined flap deflection has taken place.
- the control arrangement 6 stores the flap position continuously, so that a value for the intermediate position is stored in the memory of the control arrangement 6 in the state of the de-energized intermediate position. Based on this, the drive arrangement 5 can then be regulated to the intermediate position in the holding routine.
- the holding flap line is the deflected flap position. This is advantageous insofar as there is no possibly surprising return movement of the flap 4 as part of the holding routine.
- the predetermined flap deflection that triggers the holding routine must be defined in a suitable manner.
- the predetermined flap deflection is preferably a deflection of the flap 4 out of the respective intermediate position by a predetermined minimum flap displacement.
- the predetermined flap deflection can also be defined by a minimum flap speed and / or a minimum flap acceleration.
- the generator voltage of a drive motor 9a of the drive arrangement 5, which results when the drive train of the drive arrangement 5 is driven back can advantageously be used.
- the generator voltage can also be used to supply at least a part of the control arrangement 6 with an electrical voltage until the control arrangement 6 has been woken up in a manner to be explained.
- the sensor signal 25 of a sensor 11 assigned to the drive arrangement 1 can be monitored in the monitoring routine for detecting the predetermined flap deflection.
- the hold control loop is a control loop with a feedback loop, which in principle can also be cascaded.
- the command variable of the holding control loop is preferably the Maltese flap position, while the manipulated variable of the holding control loop is preferably the electrical voltage and / or the electrical current of at least one drive motor 9a of the drive arrangement 1.
- the control details of such a control loop are as such known from the prior art.
- the control arrangement 8 preferably has a driver unit for connecting the drive arrangement 5 to electrical drive power.
- the usual bridge circuits, in particular H-bridge circuits can be used here.
- the control arrangement 6 is equipped with a logic unit for controlling the driver unit.
- the logic unit can basically also serve other purposes.
- the logic unit can check the authentication of the operator when the flap 4 is opened. In the sense of an energy-saving operation, it is preferably provided that the control arrangement 6 is brought from an operating mode into a standby mode when the flap 4 is in an intermediate position to meet a standby condition.
- the standby mode is defined here and preferably such that the monitoring routine 7 runs, but not the holding routine 8.
- all power-consuming functions of the control arrangement 6 are deactivated in the standby mode, insofar as they are not required to wake the control arrangement 6 out of the standby mode.
- the standby condition here is and preferably the expiry of a predetermined standby time period without motor control of the drive arrangement 5.
- Other variants for the definition of the standby condition are conceivable.
- the control arrangement 6 is preferably brought into the operating mode upon detection of the predetermined flap deflection, which is preferably followed by the triggering of the holding routine 8. This can be seen in the illustration according to FIG. 3. Within the monitoring routine 7 shown schematically in FIG. 3, a monitoring step 12 takes place in which it is checked whether a flap deflection has taken place at all.
- step 13 it is checked whether the detected flap deflection meets the criteria for a predetermined flap deflection. If this is not the case, there is a jump back to monitoring step 12. If the detected valve deflection corresponds to the criteria for the predetermined flap deflection, the wake-up step 14 is triggered, which includes the transfer of the control arrangement 8 from the standby mode into the operating mode. The holding routine 8 shown in FIG. 3 is then triggered, in which the control 15 is triggered to the stop-tilt position. In the course of the regulation, a value for the restoring force generated by the drive arrangement 5 is preferably determined. In order to ensure that no excessive forces relevant to restraint act, the holding control circuit is preferably designed in such a way that the value of the restoring force is limited to a predetermined restoring force limit value.
- the respective restoring force is inferred from the electrical voltage and / or the electrical current of at least one drive motor 9a of the drive arrangement 5 based on an electrical drive model of the relevant drive motor 9a.
- the values for voltage and / or current can correspond to or be derived from the manipulated variable mentioned above.
- the particular advantage of determining a value for the restoring force is that a user request directed at an adjustment of the flap 4 can be detected, which is expressed in the user acting on the flap 4.
- the restoring force is checked by means of the control arrangement 6 in a comparison step 16 to determine whether the restoring force exceeds a predetermined actuation threshold. If the actuating threshold is exceeded by the restoring force, the holding routine 8 is left in a preferred alternative. This initially ensures that the control arrangement 6 with the holding routine 8 does not work against the user.
- an adjustment routine 18 can be triggered, as can be seen from the illustration in FIG. 3.
- a motorized adjustment of the flap 4 in particular a motorized closed adjustment into the closed position of the flap 4 or a motorized opening adjustment into the open position of the flap 4, is preferably carried out in one of the Restoring force causes opposite adjustment direction. If the user presses the flap 4 in the closing direction, a restoring force is first generated in the holding routine 8, which counteracts the force effect of the user. If the restoring force exceeds the actuation threshold, the control arrangement 6 follows the user request by appropriate actuation of the drive arrangement 5 by motorized adjustment of the flap 4 in the closing direction,
- the user expresses an adjustment request of the flap 4 in another way.
- This can be provided, for example, by actuating a radio remote control.
- the comparison step 16 is followed by a further query step 17 which is directed to the query of a possible user request and which in turn can lead to the triggering of the adjustment routine 18.
- the flap 4 is assigned an actuation sensor 19 for detecting a user actuation.
- the holding routine 8 is exited upon detection of a user actuation and / or an adjustment routine 18 explained above is triggered.
- the actuation sensor 19 is a proximity sensor for detecting a user movement.
- the actuation sensor 19 can be a force sensor for detecting a user force effect on the flap 4, in particular a hand force impressed into the flap 4 by the user.
- the drive arrangement 5 can have a motor drive 9, 10 or two motor drives 9, 10.
- the drive arrangement 5 for motorized adjustment of the flap 4 has a drive 9 and that the drive arrangement 5 for introducing a spring force into the flap 4 has a resilient spring unit, in particular a gas pressure spring unit, which is configured separately from the drive 9.
- the spring unit is preferably used to support the motor drive 9 against gravity.
- the spring unit is subject to aging behavior, in particular if the spring unit is a gas pressure spring unit.
- This aging behavior is preferably recorded by means of the control arrangement 6.
- a predetermined, in particular age-related, reduction of the spring force of the spring unit in particular a reduction of the spring force of the spring unit below a limit spring force, is detected and an error routine is then carried out.
- the limit spring force is further preferably dependent on the flap position and / or on the spring deflection of the spring unit
- a warning message regarding the aging state of the spring unit is issued in the error routine via a display device.
- a fault memory is set in the fault routine with regard to the aging state of the spring unit.
- the control arrangement 6 in the holding routine is preferably used to detect the predetermined reduction in the spring force the spring unit checks the manipulated variable in the holding control loop for the fulfillment of an error criterion.
- the error criterion is preferably defined by the fact that the manipulated variable or a time average of the manipulated variable exceeds a limit manipulated variable.
- the limit manipulated variable also preferably depends on the flap position and / or on a slope of the motor vehicle 2 and / or an ambient temperature of the motor vehicle 2. These dependencies can easily be determined in experiments and stored in a memory of the control arrangement 6.
- control arrangement 6 for carrying out the above proposed method is claimed as such. It has already been pointed out that the control arrangement 6 preferably has software that maps the proposed method
- the flap arrangement 1 set up for carrying out the proposed method is claimed as such.
- the flap arrangement 1 accordingly has a flap 4 which is adjustable relative to the motor vehicle body 3.
- the flap arrangement 1 is equipped with a drive arrangement 5 assigned to the flap 4 and an above control arrangement 6.
- the flap 4 can be pivoted about a horizontal pivot axis 4a, which, as mentioned above, can be arranged rigidly or adjustably with respect to the motor vehicle body 3. Accordingly, the gravitational force urges the flap 4 in the closing direction, as has also already been explained.
- the system friction that is to say the friction that has to be overcome for an adjustment of the flap 4, is designed in such a way that, at least in the normal state, preferably always, the flap 4 in at least one de-energized intermediate position, preferably in old intermediate positions, by means of the static system friction positions.
- flap 4 is held purely in terms of control technology, without the need for a mechanical brake.
- the normal state is defined here and preferably so that the motor vehicle 2 is on a slope which corresponds to a road gradient within +/- 40%, preferably +/- 3 ⁇ %. Outside the normal state, that is to say on an extremely steep slope, it may be that the flap 4 is held in any position purely by control technology, since the static friction for holding the flap 4 may not be sufficient.
