Description

Technical Field

[0001] This invention relates to a method for operating a ground processing machine. Background Technology

[0002] Especially for ground processing machines driven solely by electric motors, where energy for operating the electric motor is drawn from an accumulator (e.g., one or more batteries), the duration of operation is limited by the energy that can be stored in such an accumulator. Furthermore, this accumulator is limited in terms of the current flowing from it—generally referred to as battery current—so that it releases only a limited amount of energy per unit time, which is then available for use by the electrical loads in the ground processing machine. Summary of the Invention

[0003] The purpose of this invention is to provide a method for operating ground processing machines (especially ground compactors) that avoids accumulator overload.

[0004] According to the invention, this objective is achieved by a method for operating a ground processing machine (especially a ground compactor), wherein the ground processing machine includes multiple electrical loads powered by an energy storage device, in which:

[0005] - Detect the load status of the energy storage device, and when an excessive load is detected, disable at least one electrical load or / and reduce the power consumption of at least one electrical load.

[0006] or / and

[0007] - To prevent the energy storage device from entering an overloaded state, the electrical load is operated with a time delay.

[0008] Using this method, by operating the electrical load in the ground processing machine at this power consumption or a mutually coordinated power consumption, it is possible to at least temporarily avoid the simultaneous operation or start-up of loads that would subject the energy storage device to a heavy load, thereby keeping the load on the energy storage device at or limiting it to a certain level. This means that on the one hand, energy storage device damage can be prevented, and on the other hand, the energy stored in the energy storage device can be used effectively.

[0009] To provide information about the accumulator load, the current from the accumulator can be detected. When the current intensity from the accumulator exceeds a current intensity threshold, an overload condition is identified. Here, the intensity of the currently flowing current or the time-averaged current intensity can be considered.

[0010] In order to further avoid overload of the energy storage unit, considering the release measures proposed by the method according to the invention, if an overload condition of the energy storage unit is still identified after disabling at least one electrical load or / and reducing the power consumption of at least one electrical load, at least one additional electrical load shall be disabled or / or the power consumption of at least one additional electrical load shall be reduced.

[0011] To reduce the load on the energy storage unit, for example when the energy storage unit is overloaded, the energy load can be gradually deactivated in a way that reduces power consumption, or / and the power consumption of the energy load can be gradually reduced in a way that reduces power consumption, so that the effect is first applied to the energy load with higher power consumption, and then applied to the energy load with lower power consumption if the energy storage unit is still overloaded.

[0012] If a release strategy considers the loads on the accumulator generated by different electrical loads, and the release strategy should first act on the electrical loads that cause a larger load on the accumulator, and then act on the electrical loads that cause a smaller load on the accumulator, so as to achieve the most efficient release of the accumulator, then for such a release strategy, it is possible to act on the electrical loads progressively in groups a), b), and c), that is: first act on at least one electrical load of group a), and if the accumulator still has an excessively high load after acting on at least one electrical load of group a), act on at least one electrical load of group b), and if the accumulator still has an excessively high load after acting on at least one electrical load of group b), act on at least one electrical load of group c), wherein the electrical loads according to groups a), b), and c) include:

[0013] a) At least one electric motor in the travel hydraulic circuit, which drives at least one travel hydraulic pump.

[0014] b) At least one unbalanced electric motor that drives the unbalanced mass of an unbalanced component distributed for ground processing rollers.

[0015] c) At least one small electrical load, wherein the small electrical load includes: a cooler blower motor for cooling electronic components and / or a cooler blower motor for cooling hydraulic fluid and / or a seat heater and / or a console heater and / or an air conditioning unit and / or a water pump and / or an additive pump and / or work lighting equipment and / or driving lighting equipment and / or audio equipment and / or a fresh air / recirculated air blower motor and / or a socket.

[0016] In an alternative release strategy, the importance of different electrical loads used to operate the ground processing machine can be considered. This is achieved by gradually applying the energy loads according to their respective groups (e), (f), and (g). Specifically, the energy load is first applied to at least one electrical load in group (e), and if the accumulator still has an excessive load after applying to at least one electrical load in group (e), it is applied to at least one electrical load in group (f), and if the accumulator still has an excessive load after applying to at least one electrical load in group (f), it is applied to at least one electrical load in group (g). The electrical loads according to groups (e), (f), and (g) include:

[0017] e) at least one small electrical load, wherein the small electrical load includes: a cooler blower motor for cooling electronic components and / or a cooler blower motor for cooling hydraulic fluids and / or a seat heater and / or a workbench heater and / or an air conditioning unit and / or a water pump and / or an additive pump and / or work lighting and / or driving lighting and / or audio equipment and / or a fresh air / recirculated air blower motor and / or a socket.

[0018] f) At least one travel motor in the travel hydraulic circuit, which drives at least one travel hydraulic pump.

[0019] g) At least one unbalanced electric motor that drives the unbalanced mass of an unbalanced component distributed to the ground processing roller.

[0020] This strategy first disables or reduces the power consumption of electrical loads that have a relatively minor direct impact on the desired outcome—such as the required ground compaction. Only when the action on these less important electrical loads fails to result in sufficient energy release from the accumulator are the more important electrical loads gradually introduced and applied to achieve further energy release from the accumulator.

[0021] The ground processing machine may include at least two ground processing rollers, each having an imbalance component having at least one unbalanced mass that can be driven to rotate by at least one unbalanced electric motor, wherein if an overload condition of the accumulator is detected during the operation of the imbalance components of the at least two ground processing rollers, the imbalance component assigned to one of the ground processing rollers is deactivated or operated at a lower speed, and wherein if an overload condition of the accumulator still exists, the imbalance component assigned to the other of the ground processing rollers is deactivated or operated at a lower speed.

[0022] It can also be configured such that the ground processing machine includes at least two ground processing rollers, each of the at least two ground processing rollers having an imbalance component, the imbalance component having at least one imbalance mass that can be driven to rotate by at least one imbalance electric motor, wherein the imbalance component assigned to one of the ground processing rollers includes a vibration component for generating a force acting substantially orthogonally to the rotation axis of the one ground processing roller, and the imbalance component assigned to the other ground processing roller includes an oscillation component for generating a force acting substantially tangentially to the rotation axis of the other ground processing roller, wherein if an overload condition of the accumulator is detected during the operation of the imbalance components of the at least two ground processing rollers, the imbalance component assigned to the other ground processing roller is deactivated or operated at a lower speed, and wherein if an overload condition of the accumulator still exists, the imbalance component assigned to the one ground processing roller is deactivated or operated at a lower speed.

[0023] In another design, the ground processing machine includes at least one ground processing roller having an unbalanced assembly having at least one unbalanced mass that can be driven to rotate by at least one unbalanced electric motor. The unbalanced assembly can operate in vibratory operation to generate a force acting substantially orthogonally to the axis of rotation of the ground processing roller, and can operate in oscillating operation to generate a force acting substantially tangentially to the axis of rotation of the ground processing roller. If an overload condition of the accumulator is detected during oscillating operation of the unbalanced assembly of the at least one ground processing roller, the oscillating operation of the unbalanced assembly is terminated or continues at a lower speed. Or / and if an overload condition of the accumulator is detected during vibratory operation of the unbalanced assembly of the at least one ground processing roller, the vibratory operation is terminated or continues at a lower speed.

[0024] A fully electrically operated ground processing machine may include at least one travel motor driving at least one travel hydraulic pump in a travel hydraulic circuit and at least one steering motor driving at least one steering hydraulic pump in a steering hydraulic circuit. In such a ground processing machine, to prevent accumulator overload, at least one (preferably each steering motor) can be started before at least one (preferably each travel motor) when the ground processing machine begins operation. Therefore, even when the accumulator has been released, sufficient steering assistance or maneuverability is ensured when the ground processing machine begins to move on the surface to be processed.

[0025] In particular, when the ground processing mechanism acts as a ground compactor, the ground processing machine may include at least one ground processing roller having an imbalance component having at least one imbalance mass that can be driven to rotate by at least one imbalance electric motor. To avoid overloading the accumulator, at least one travel motor (preferably each travel motor) may be started before at least one imbalance electric motor (preferably each imbalance electric motor) when the ground processing machine starts running.

[0026] In the method according to the invention, the charging state of the energy storage device can also be continuously detected, and when a state of low energy storage device charge is detected, at least one power load can be deactivated or / and the power consumption of at least one power load can be reduced. Attached Figure Description

[0027] The invention will now be described in more detail with reference to the accompanying drawings. The drawings show:

[0028] Figure 1 A ground processing machine configured as a ground compactor is shown;

[0029] Figure 2 A simplified diagram is shown. Figure 2 The structure of the hydraulic system of the ground processing machine;

[0030] Figure 3 Simplified representation Figure 1 The unbalanced components of the ground processing rollers of the ground processing machine. Detailed Implementation

[0031] Figure 1 The ground compactor 10 shown and configured as a ground compactor includes ground processing rollers 14 on a rear vehicle 12, each having an imbalance component 16 allocated to and at least partially disposed therein. On a front vehicle 20, which is pivotally connected to the rear vehicle 12 in an articulated connection area 18 to steer the ground compactor 10, the ground compactor 10 includes another ground processing roller 22, which has an imbalance component 24 allocated to and at least partially disposed therein. The rear vehicle 12 also has an open-constructed control panel 26 in the illustrated embodiment, whereby an operator can, for example, operate a steering wheel 28 to steer the ground compactor and operate a throttle lever 30 to preset the ground compactor's speed in the forward or backward driving direction.

[0032] exist Figure 2 A simplified schematic diagram illustrates the hydraulic system 32 mounted on the ground compactor 10. The hydraulic system 32 includes a travel hydraulic circuit 34 and a steering hydraulic circuit 36 ​​as its main components.

[0033] The travel hydraulic circuit 34 includes a travel hydraulic pump 40 driven by a travel electric motor 38 and two travel hydraulic motors 42 and 44. The travel hydraulic motor 42 can be distributed to the ground processing rollers 14 mounted on the rear vehicle, and the travel hydraulic motor 44 can be distributed to the ground processing rollers 22 mounted on the front vehicle 20, so that the ground processing rollers 22 on the travel hydraulic pump 40 rotate when the travel electric motor 38 is running.

[0034] The steering hydraulic circuit 36 ​​includes a steering hydraulic pump 48 driven by a steering motor 46. The steering hydraulic pump 48 delivers fluid (e.g., hydraulic oil) from a reservoir 50 to a steering assembly 52, which converts the rotational motion of the steering wheel 28 into the regulating motion of one or two steering piston / cylinder units 54, thereby causing the front vehicle 20 and the rear vehicle 12 to swing relative to each other in the articulated connection area 18, and thus steering the ground compactor 10. The fluid delivered by the steering hydraulic pump 48 can be fed back to the reservoir 50 via the travel hydraulic circuit 34.

[0035] In hydraulic system 32, the travel motor 38 and steering motor 46 represent electrical loads. Other electrical loads can be found in the unbalance components 16 and 24. For example, according to... Figure 3 As can be seen in the unbalanced assembly 16 of the ground processing roller 14, each such unbalanced assembly includes at least one unbalanced electric motor 54, which drives at least one unbalanced mass 56, configured with a center of gravity M eccentric relative to the unbalanced rotation axis U, to rotate about the unbalanced axis U. Figure 3 The design example of the unbalanced component 16, as seen in the diagram, corresponds to the unbalanced rotation axis U of the rotation axis D of the ground processing roller 14. This is achieved by the unbalanced mass 56 rotating about the unbalanced axis U, which applies a force oriented substantially orthogonally to the rotation axis D of the roller, thus causing the ground processing roller to vibrate. Therefore, the unbalanced component 16, constructed or operable in this manner, provides a vibration component.

[0036] In this alternative design of the unbalanced components 16, 24, at least two unbalanced masses can be provided, each having an unbalanced rotation axis offset from and parallel to the roller rotation axis D, wherein the unbalanced rotation axes of these unbalanced masses can be arranged opposite each other relative to the roller rotation axis D. This unbalanced component can operate such that it generates a force tangential to the roller rotation axis, thus causing the ground processing roller to oscillate, in which the ground processing roller is periodically accelerated or decelerated to rotate about the roller rotation axis. In this case, the unbalanced component forms an oscillating component. Alternatively, this unbalanced component—constructed to include two or at least two unbalanced masses having unbalanced rotation axes offset from the roller rotation axis—can also operate such that the rotating unbalanced masses generate a force orthogonally oriented to the roller rotation axis, so that in this case, the unbalanced component can operate as a vibration component.

[0037] The unbalanced electric motor 54 of the unbalanced assembly 16, or each unbalanced electric motor 54 mounted on the ground processing machine 10, provides an electrical load, which, like the travel motor 38 and the steering motor 46, is fed by an energy storage unit 58 (e.g., at least one battery). Other electrical loads are also fed by the energy storage unit 58. Figure 1 and Figure 2 Other electrical loads generally referred to as 60 in the overall designation can be called small loads, whose energy consumption is relatively small compared to the energy consumption of the drive motor 38, the steering motor 46, or each unbalanced electric motor 54. Such small loads 60 can include, for example, those in… Figure 1 and Figure 2 The seat heater 62 on the operator's seat 64 in the control panel 26 shown may also include, for example, a cooler blower motor, which drives a blower to cool electronic components. Additionally, this small load 60—especially in the enclosed control panel 26—includes a control panel heater or air conditioning equipment. If a spraying device is provided on the floor processing machine 10 corresponding to at least one of the floor processing rollers 14, 22, the spraying device can be used to spray the floor processing rollers to prevent material from adhering to them. The small load 60 may include a water pump or additive pump to generate, for example, a mixture of water and liquid additives for spraying onto the surfaces of the floor processing rollers 14, 22, or to spray these liquids onto the surfaces of the floor processing rollers 14, 22. Figure 1The driving lighting equipment 66 shown, which enables the ground processing machine 10 to move on open roads, or the special work lighting equipment that can better illuminate the work area, can be configured as a small load 60, such as an audio device or socket installed in the area of ​​the workbench 26, through which power can be supplied to additional equipment on the ground processing machine 10. The blower motor for the fresh air / recirculated air blower for the workbench 26 can also be configured as a small load 60, especially when the workbench 26 is enclosed.

[0038] The energy storage device 58, configured as a battery (e.g., a lithium-ion battery), can only be loaded to a limited extent during operation, meaning it can only operate at a limited current (e.g., a few hundred amperes). Higher currents from such an energy storage device can damage it and must therefore be avoided. In particular, when multiple electrical loads in the ground compactor 10 are simultaneously fed by the energy storage device 58, a state can occur where the current from the energy storage device 58 is too high and, for example, exceeds the current intensity threshold.

[0039] In order to identify the occurrence of this state, a load monitoring component 68, including a current sensor, is assigned to the energy storage unit 58. This load monitoring component 68 outputs a signal corresponding to the current. This signal can be evaluated in the control unit of the ground compactor 10 and used as the basis for driving or operating different electrical loads set on the ground processing machine 10 in the manner described below.

[0040] To avoid overloading the accumulator 58 when the ground processing machine 10 starts running, electrical loads, especially those with high power consumption and causing high loads (i.e., high currents) on the accumulator 58, are prevented from operating simultaneously. For example, it can be configured such that when the ground processing machine 10 needs to run, i.e., when it needs to work in compaction operations, the steering motor 46 is activated first to provide sufficient hydraulic pressure in the steering hydraulic circuit 36, thereby ensuring the steering capability of the ground processing machine 10. The travel motor 38 can be activated with a time delay relative to the start-up time of the steering motor 46, i.e., voltage is applied to drive the travel hydraulic pump 40 and thus move the ground processing machine 10. Because relatively high currents occur, especially during the operation of motors 46 and 38, the time delay ensures that the load peaks do not occur simultaneously when activating the two motors 46 and 38.

[0041] If the ground processing machine 10 moves at this time, it can also excite the unbalanced electric motors 54 assigned to the unbalanced components 16, 24. Here, for example, the unbalanced electric motors 54 provided in the two unbalanced components 16, 24 can be made to run simultaneously. In order to avoid simultaneous load peaks in this stage, it can be alternatively set such that the unbalanced electric motors 54 provided in the two unbalanced components 16, 24 run with a time delay relative to each other, so that one of the unbalanced electric motors 54 is energized, for example, only after the other unbalanced electric motor has been rotating at a speed within the range of the theoretical speed set for unbalanced operation. If one or two unbalanced components 16, 24 have multiple unbalanced electric motors 54, these unbalanced electric motors can also operate out of order.

[0042] During the initial operation phase of the ground compactor 10, to avoid load peaks on the accumulator 58, electrical loads that are less critical to the operation of the ground compactor 10 can be kept off or operated at lower power consumption. This involves, for example, small loads 60. Thus, for example, when the ground compactor 10 starts operating, the operation of the seat heater 62 or the full-power operation of the air conditioning equipment can be canceled.

[0043] If the ground processing machine 10 is in operation, i.e., moving on a surface to be compacted to compact asphalt material, it is possible that the current in the accumulator 58 may reach or exceed the current intensity threshold. This could happen, for example, when the ground processing machine 10, which initially moves on a relatively level surface, moves into a sloping area—i.e., requires uphill movement. If the traveling speed of the ground processing machine 10 needs to be maintained in this state, this will result in a significant increase in the load on the accumulator 58 applied by the travel motor 38.

[0044] If an excessive load occurs in the accumulator 58, which can be identified, for example, by reaching or exceeding a current intensity threshold, different measures can be taken to reduce the load on the accumulator 58. In particular, different strategies can be set to reduce the load on the accumulator 58.

[0045] For example, this release strategy could specify that measures to achieve a relatively significant reduction in the load on the accumulator 58 should be taken first. As previously mentioned, it can generally be assumed that the travel motor 38 is at maximum load on the accumulator 58; for example, this release strategy could first act on the travel motor 38 to reduce its rotational speed, thereby reducing the speed at which the ground processing machine 10 moves on the surface to be processed. The reduction in the travel speed of the ground processing machine 10 can be achieved, for example, in multiple steps, continuously, or, for example, continuously between individual steps, until a minimum travel speed that cannot be lowered for achieving the desired processing result is reached.

[0046] If reducing the travel speed by correspondingly controlling the travel motor 38 does not achieve the desired result, other system areas can be controlled at a power consumption level to reduce the load on the energy storage device 58. For example, unbalanced components 16, 24 or their unbalanced electric motors 54 can be considered such system areas. If the load on the energy storage device 58 remains too high even when the travel speed of the ground processing machine 10 is reduced, a lower release level can be applied to the unbalanced components 16, 24. Here, for example, one of the unbalanced components can be deactivated first, or its unbalanced mass 56 can be driven at a lower speed to rotate around the corresponding unbalanced rotation axis U. If, in one of the unbalanced components 16, 24, the reduced speed does not cause sufficient release of the energy storage device 58 in the other unbalanced component operating normally, the unbalanced component whose power consumption has been reduced can be completely deactivated at this point, while the other unbalanced component can continue to operate normally, or the other unbalanced component can also further reduce its power consumption and drive its unbalanced mass 56 at a reduced speed. The power reduction in one or two unbalanced components 16, 24 can also be achieved in multiple stages if necessary. If the power reduction or deactivation of one of the unbalanced components 16, 24 does not cause the energy storage 58 to be fully released, the other unbalanced component can also be deactivated or its power reduction is reduced, so that at least temporarily no unbalanced components 16, 24 are in operation and no ground processing rollers 14, 22 enter vibratory motion.

[0047] In another variation, unbalanced components 16 and 24 can be installed in the two ground processing machines 14 and 22, which can operate in both oscillating and vibrating operation. In this case, to reduce the load on the accumulator 58, when one of the unbalanced components 16 and 24 is operating in oscillating operation, this unbalanced component continues to oscillate, for example, at a reduced speed, while the unbalanced component of the corresponding ground processing roller continues to operate in vibrating operation without change. If the release introduced by this method in the accumulator 58 is insufficient, the oscillating operation can be terminated, while the vibrating operation is initially maintained in the other ground processing roller. To further release the accumulator 58, the vibrating operation can also continue at a reduced speed, and if this does not result in a sufficient release of the accumulator 58, the unbalanced component that was initially operating in vibrating operation is also completely deactivated. In principle, the power consumption of the unbalanced component operating in vibrating operation can also be gradually reduced first, and then, if necessary, the unbalanced component operating in oscillating operation can also be affected to reduce power consumption.

[0048] If the action set at the second level of the release level, especially on different unbalanced components, does not result in sufficient release of the energy storage 58, then the action at the third level of the release level can be applied to the small load 60 to further reduce the current in the energy storage 58 by disabling at least a portion of the small load 60 and / or by reducing the power consumption of at least a portion of the small load 60.

[0049] In alternative strategies for releasing the accumulator 58, the priority of the impact on different electrical loads is not based on the release contribution achieved separately, but rather on the importance of the respective loads to the operation to be performed. For example, if the ground is compacted using the floor machine 10, sufficient rotational speed in the corresponding unbalanced components 16, 24 and sufficient travel speed of the floor machine 10 are of paramount importance, while sufficient heating of the workbench 26 or full illumination of the ground to be processed are of secondary importance. Therefore, this priority can be configured, for example, such that when an overload condition of the accumulator 58 is detected, the small load 60 is acted upon first, and the small load is deactivated or its power consumption is reduced as long as it is not necessary for operation. Thus, for example, the cooler blower motor and the blower motor for the fresh air / recirculated air blower can be operated at lower speeds. Seat heaters or heaters for the workbench—since they are not directly related to the desired work effect—can be deactivated at the first level of the release level or operated at lower power consumption.

[0050] If the first-stage release does not result in a full release of the accumulator 58, a second-stage release can be applied to the drive motor 38 to reduce its speed and power consumption, thereby decreasing the travel speed of the ground processing machine 10. This significantly contributes to the release of the accumulator 58.

[0051] Because the travel speed of the ground processing machine 10 is usually less important to the working effect than the operation of the unbalanced components 16 and 24, the unbalanced components 16 and 24 are only acted on in the third level of release level, for example, in the manner described in detail above, before the reduction in travel speed—that is, the effect on the travel motor 38—has caused the accumulator 58 to be fully released.

[0052] Different measures have been described above, which are preferably used individually or in combination in a mutually constrained and coordinated manner, so as not to overload the accumulator 58 supplying different electrical loads during the operation of the ground processing machine 10 or to continue releasing energy only when an overload condition occurs. These measures are preferably adopted in coordination with each other within the aforementioned levels, but of course they can also be adopted arbitrarily (e.g., through manual interaction by the operator) when the corresponding operating state of the ground processing machine 10 makes this seem advantageous.

[0053] The measures required according to the present invention for releasing the accumulator can be used in ground processing machines or ground compactors of various designs. For example, in Figure 1 As shown, such a floor processing machine may have two floor processing rollers arranged sequentially along its longitudinal direction. Alternatively, such a floor processing machine may have floor processing rollers only on the front carriage, while drive wheels are provided on the rear carriage. Rubber wheel rollers capable of rotating about a common axis of rotation may also be used as floor processing rollers, and two floor processing rollers with metal covers may be arranged adjacent to each other, i.e., sequentially arranged in the direction of the roller's axis of rotation.
