[0048] Example embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While example embodiments of the present disclosure are described herein, the present disclosure is not limited to these embodiments, but instead, includes all alternatives consistent with the scope of the present disclosure. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0049] It is to be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order

[0050] Although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first," "second," and the like can be used herein to describe a variety of elements, components, regions, layers and / or sections. Thus, the first element, component, region, layer or section discussed below can be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

[0051] To facilitate description, spatially relative terms can be used herein for the purpose of describing one element or feature's relationship to another element or feature as illustrated in the figures. Such spatially relative terms include "internal", "external", "lateral", "longitudinal", "upper", "lower", "above", "below", "left", "right", and the like. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0052] The harvester is an agricultural machine for harvesting crops. The crops that can be harvested by the harvester include, but are not limited to, wheat, corn, soybean, sorghum, millet, rapeseed and quinoa. When the harvester is working, the engine drives the working device to harvest crops. When the engine is started, it needs to be started by the starter. The starter can convert electrical energy into mechanical energy to drive the engine flywheel to rotate, thereby realizing the starting of the engine.

[0053] During the working process of the harvester, there is a situation of load shutdown. When the harvester is shut down with load and restarted, in addition to overcoming the resistance of the engine itself, the resistance of the working device of the harvester also needs to be overcome, thereby causing the starter to need to overcome a larger load when the harvester is started, which leads to the starter being easily damaged, and in turn, the harvester being easily damaged.

[0054] In order to at least solve the problem that the harvester needs to overcome a larger load when it is shut down with load and restarted, an embodiment of the present application proposes a harvester shutdown method, which can unload when the harvester is shut down with load, thereby reducing the load that needs to be overcome when restarted.

[0055] Unloading means unloading the load of the working device of the harvester.

[0056] The method for stopping the harvester according to the embodiments of the present application will be described below in combination with the accompanying drawings.

[0057] As shown in Figure 1 , the method for stopping the harvester according to the embodiments of the present application comprises:

[0058] S100, acquiring working condition data, the working condition data being used to represent the working condition state of the harvester;

[0059] S200, judging the working condition of the harvester according to the working condition data;

[0060] S300, according to the fact that the harvester is in the loaded working condition and in response to the signal of engine stop, controlling the neutral gear, disconnecting the main clutch, and controlling the harvester to stop and shut down.

[0061] The working condition means the working state of the machine under specific conditions. For the harvester, the harvester can be in the loaded working condition with load, for example, the harvesting working condition, the stationary loaded working condition, etc. It can be understood that according to the actual situation, the harvester can also not be in the loaded working condition, for example, the harvester can be in the unloaded working condition, etc.

[0062] S100, acquiring working condition data, the working condition data being used to represent the working condition state of the harvester;

[0063] As an example, the working condition data can be the drum rotating speed, the harvester speed, etc. The drum rotating speed and the engine rotating speed can reflect the working condition of the harvester.

[0064] Optionally, the working condition data is collected by a sensor.

[0065] S200, judging the working condition of the harvester according to the working condition data;

[0066] The working condition of the harvester is judged by processing the working condition data.

[0067] In combination with Figure 1 , Figure 2 and Figure 6 , in some specific embodiments, the working condition data comprises the drum rotating speed and the harvester speed, the loaded working condition comprises the stationary loaded working condition and the harvesting working condition, and the step of S200, judging the working condition of the harvester according to the working condition data, comprises:

[0068] judging whether the drum rotating speed is 0;

[0069] judging whether the harvester speed is 0 according to the fact that the drum rotating speed is not 0;

[0070] judging that the harvester is in the stationary loaded working condition according to the fact that the harvester speed is 0;

[0071] According to the harvester speed is not 0, it is judged that the harvester is in the harvesting working condition.

[0072] According to the roller speed is not 0, it is indicated that the harvester is in the load working condition, and the specific working condition of the harvester is further judged by the harvester speed.

[0073] According to the roller speed is not 0 and the harvester speed is 0, it is indicated that the harvester is in the load working condition at the original position, and therefore, it is judged that the harvester is in the load working condition at the original position.

[0074] According to the roller speed is not 0 and the harvester speed is not 0, it is indicated that the harvester is in the harvesting working condition, and therefore, it is judged that the harvester is in the harvesting working condition.

[0075] Therefore, the specific working condition of the harvester can be judged by the roller speed and the harvester speed.

[0076] Optionally, the harvester speed is collected by the VCU control vehicle speed sensor, and the roller speed is collected by the VCU control roller speed sensor.

[0077] VCU (Vehicle Control Unit, vehicle controller) controls the action execution of the related parts of the whole vehicle.

[0078] S300, according to the harvester is in the load working condition, and in response to the fire signal, the empty gear is controlled, the main clutch is disconnected, and the harvester is controlled to stop and fire.

[0079] Optionally, the action of the empty gear relay is controlled to make the harvester hang the empty gear. Therefore, the harvester hanging the empty gear can be realized.

[0080] The relay is an automatic switch used in an automatic control circuit to control the operation of a large current by a small current.

[0081] In some optional embodiments, the action of the main clutch relay is controlled to make the main clutch disconnected. Therefore, the control of disconnecting the main clutch can be realized.

[0082] According to the harvester is in the load working condition, and the fire signal is received, the empty gear is controlled, and the main clutch is controlled to be disconnected, so as to unload the harvester.

[0083] The harvester stopping method of the embodiment of the application judges the working condition of the harvester by the working condition data, controls the empty gear and controls the main clutch to be disconnected when the harvester is in the load working condition and the fire signal is received, so as to unload the harvester. Therefore, the harvester can be unloaded when the harvester is fired with load, so as to reduce the load to be overcome when restarting.

[0084] Combined withFigure 3 and Figure 6 As shown in FIGS. 1, 2, 3, and 4, in some embodiments, according to that the harvester is in the load carrying working condition and in response to the shutdown signal, the step of controlling the neutral gear, disconnecting the main clutch, and controlling the shutdown of the harvester comprises:

[0085] According to that the harvester is in the harvesting working condition, in response to the shutdown signal, it is judged whether the shutdown signal is sent by the shutdown terminal;

[0086] According to that the shutdown signal is sent by the shutdown terminal, it is judged that the shutdown is a misoperation, the neutral gear is controlled, the main clutch is disconnected, and the shutdown is controlled.

[0087] The shutdown terminal refers to a shutdown circuit, the shutdown circuit comprises a shutdown switch, according to the operation of the shutdown switch, the shutdown circuit sends a shutdown signal, so that the harvester can be shut down.

[0088] According to that the harvester receives the shutdown signal from the shutdown terminal when the harvester is in the harvesting working condition, it is indicated that the driver of the harvester has a misoperation of operating the shutdown switch, the neutral gear is controlled, and the main clutch is disconnected, so as to unload the harvester. Thus, the harvester can be unloaded when it is shut down with load, so as to reduce the load to be overcome when restarting.

[0089] Further, according to that the shutdown is judged to be a misoperation, a prompt signal is sent, the prompt signal is used to indicate that the prompt terminal sends the prompt information of the misoperation shutdown. Thus, the driver can be prompted to have a misoperation.

[0090] In some possible embodiments, the prompt terminal can be a sound box, and the prompt information of the misoperation shutdown is sent by playing voice.

[0091] In combination with Figure 4 and Figure 6 As shown in FIGS. 1, 2, 3, and 4, in some embodiments, according to that the speed of the harvester is not 0, it is judged that the harvester is in the harvesting working condition, and the method for stopping the harvester further comprises:

[0092] According to that the harvester is in the harvesting working condition, in response to that the shutdown signal is not received, the throttle opening is acquired and judged;

[0093] According to that the throttle opening is 100%, the engine speed of the harvester is acquired;

[0094] According to that the engine speed meets a preset condition, the neutral gear is controlled.

[0095] According to that the preset condition is met, the neutral gear is controlled.

[0096] The throttle opening degree refers to the degree to which the engine throttle is opened. The throttle opening degree can reflect the engine air intake and fuel supply. It can be understood that the range of the throttle opening degree is 0% to 100%. When the throttle opening degree is 0%, the throttle is closed. When the throttle opening degree is 100%, the throttle opening degree reaches the maximum.

[0097] The preset condition is satisfied when the engine speed is less than a first threshold value. Alternatively, a decrease value of the engine speed in a unit time is greater than a second threshold value. Alternatively, the engine speed is less than the first threshold value and the decrease value of the engine speed in the unit time is greater than the second threshold value.

[0098] The engine speed being less than the first threshold value and the decrease value of the engine speed in the unit time being greater than the second threshold value both indicate that the harvester bears too large a load of materials. The engine is at risk of being pressed out and there is a risk that the materials block the harvester. When the throttle opening degree is 100%, the driver cannot solve the problem that the harvester bears too large a load of materials by increasing the throttle opening degree. Therefore, the control of the neutral gear can reduce the load and digest the materials, thereby reducing the load of the harvester and reducing the probability of the engine being pressed out.

[0099] As some examples, the first threshold value is 700 rpm (revolutions per minute).

[0100] As some examples, the second threshold value is 100 rpm and the unit time is 1 second.

[0101] As a possible implementation, the engine speed at a first time is obtained and the engine speed at a second time is obtained. The interval between the first time and the second time is the value of the unit time. The decrease value of the engine speed in the unit time is obtained by subtracting the engine speed at the second time from the engine speed at the first time. For example, the engine speed at a first time is obtained and the engine speed at the next second (i.e., the engine speed at a second time) is obtained. The decrease value of the engine speed in the unit time is obtained by subtracting the engine speed at the second time from the engine speed at the first time.

[0102] In combination Figure 4 and Figure 6 As shown in FIG. 8, in some other embodiments, the preset condition is not satisfied and no action is performed.

[0103] It should be noted that no action means no unloading action.

[0104] The preset condition is not satisfied, the probability of the engine being pressed out is relatively small, and no action is performed to avoid hindering the operation of the harvester.

[0105] AsFigure 4 As shown in some embodiments, according to the preset condition being met, after the neutral gear is controlled to be engaged, the harvester shutdown method further comprises:

[0106] determining whether the preset condition is met;

[0107] controlling the main clutch to be disconnected according to the preset condition being met.

[0108] According to the preset condition being met, the main clutch is controlled to be disconnected, which can further reduce the load, thereby achieving unloading of the harvester before the harvester is shut down.

[0109] As shown in some embodiments, according to the preset condition being met, after the neutral gear is controlled to be engaged, the harvester shutdown method further comprises: Figure 4 and Figure 6 As shown in some embodiments, according to the preset condition not being met, no action is performed.

[0110] It should be noted that no action means no unloading action.

[0111] According to the preset condition not being met, the neutral gear has achieved a better material digestion effect, and the probability of the engine being pressed out is relatively small, so no action is performed to avoid hindering the operation of the harvester.

[0112] As shown in some embodiments, according to the harvester being in the harvesting working condition, after the throttle opening degree is obtained and determined in response to the shutdown signal not being received, the harvester shutdown method further comprises: Figure 5 and Figure 6 As shown in some embodiments, according to the harvester being in the harvesting working condition, after the throttle opening degree is obtained and determined in response to the shutdown signal not being received, the harvester shutdown method further comprises:

[0113] obtaining the engine speed according to the throttle opening degree being less than 100%;

[0114] obtaining a judgment time according to the engine speed and a third threshold value, the judgment time being a continuous accumulation time during which the throttle opening degree is less than 100% and the engine speed is less than the third threshold value;

[0115] comparing the judgment time with a fourth threshold value;

[0116] controlling the neutral gear to be engaged and the main clutch to be disconnected according to the judgment time being greater than the fourth threshold value.

[0117] The continuous accumulation time during which the throttle opening degree is less than 100% and the engine speed is less than the third threshold value means that both conditions are met and the time during which both conditions are continuously met. According to the throttle opening degree being less than 100% and the engine speed being less than the third threshold value, one or both conditions are not met at a time, and the judgment time should be stopped or restarted.

[0118] When the engine speed is less than the third threshold value, the harvester bears a larger load, and when the throttle opening is less than 100%, the driver should increase the throttle opening to increase the engine speed to reduce the risk of engine stall.

[0119] However, when the driver does not properly operate and continuously does not increase the throttle opening, the judgment time is greater than the fourth threshold value, and the engine is more likely to be stalled, the control engages the neutral gear and controls the disconnection of the main clutch to further reduce the load to unload the harvester before the harvester is stalled.

[0120] As some examples, the third threshold value is 700 rpm. The fourth threshold value can be determined by the model of the engine.

[0121] In combination Figure 5 and Figure 6 As shown in some embodiments, according to the judgment time being less than or equal to the fourth threshold value, no action is taken.

[0122] It should be noted that no action means not performing unloading action.

[0123] According to the judgment time being less than or equal to the fourth threshold value, the engine is less likely to be stalled, and no action is taken to avoid hindering the operation of the harvester.

[0124] In some embodiments, after S200, the harvester shutdown method further comprises:

[0125] According to the harvester not being in the load-bearing condition, in response to the stall signal, the harvester is controlled to be shut down.

[0126] According to the harvester not being in the load-bearing condition, the harvester can be normally shut down.

[0127] In combination Figures 2 to 6 As shown in some embodiments, optionally, according to the drum speed being 0, the harvester is not in the load-bearing condition, and in response to the stall signal, the harvester is controlled to be shut down.

[0128] It should be understood that although each step in the flowchart involved in each of the above-described embodiments is shown in sequence according to the direction of the arrow, these steps are not necessarily executed in sequence according to the direction of the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each of the above-described embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or stages in other steps.
