[0050] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0051] The following combination Figures 1-6 The present invention describes a power control method and device for a hybrid working machine and the working machine.

[0052] Figure 1 It is a flow chart of the power control method of the hybrid working machine provided by the present invention.

[0053] like Figure 1 As shown, an embodiment of the present invention provides a power control method for a hybrid working machine, which may be executed by a vehicle-mounted control system and mainly includes the following steps:

[0054] 101. Obtain a control signal of a power control structure, where the power control structure is an independent control structure provided on a hybrid working machine.

[0055] Among them, the hybrid operating machinery takes a hybrid crane as an example, and the hybrid crane is a crane in which the power includes two power modes: fuel power and electric power. Of course, it should be noted that the hybrid in the present invention is described using fuel and electric energy as examples, and in actual applications it can also be applied to two other power sources, including gas as a power source or hydrogen energy as a power source, etc., all of which are inventions and creations using the same principle and all fall within the scope of protection of the present invention.

[0056] In a specific implementation process, the power control structure includes structures such as buttons, and buttons are used as an example for explanation. When the operator operates the hybrid working machine, he only needs to realize power control by pressing buttons, that is, to control the hybrid working machine according to the number of times the button is pressed or the time information. And the power control structure is an independent control structure, that is, a control structure. Specifically, the button is a control button, which can be set at the corresponding position in the cab of the working machine. The independent control structure can be understood as a structure that can realize power control alone, that is, the control of fuel power and electric power is realized through a control structure. An independent control structure realizes power control, which is simpler to operate and more efficient than the coordinated operation of the operating room and the cab. Of course, the power control structure is not necessarily a button, but can also be other structures.

[0057] In the specific application process, the control signal of the power control structure is detected in real time. The detection method can be through a sensor or other detection methods. As long as the control signal of the power control structure can be accurately detected, subsequent power control operations can be performed according to the control signal sent by the user through the power control structure.

[0058] 102. When it is detected that the control signal indicates a first preset number of intermittent operations within a first preset time period, control the hybrid working machine to switch between the engine working state and the motor working state.

[0059] Specifically, after obtaining the control signal from the power control structure, the control signal is analyzed and processed to determine the type of the control signal. For example, if the control signal is determined to indicate intermittent operation for a first preset number of times within a first preset duration, this indicates that the control signal is to perform a power switching operation, controlling the hybrid working machine's power switching between the engine and the motor.

[0060] Specifically, if the control signal indicates that the key has been pressed n times consecutively within t1 seconds, the control signal is a power switching signal. For example, if the key is pressed twice within 1 second, the control signal corresponds to a power switching command, thereby switching the hybrid working machine between engine and motor operation. This allows the power switching operation to be executed according to the operator's keystroke command.

[0061] 103. When it is detected that the control signal indicates a second preset number of intermittent operations within a second preset time period, the hybrid operating machine is controlled to stop operating.

[0062] Specifically, after obtaining the control signal from the power control structure, the control signal is analyzed and processed to determine the type of the control signal. If it is determined that the control signal indicates intermittent operation for a second preset number of times within a second preset time period, indicating that the control signal indicates a need to control the power start and stop of the hybrid working machine, the hybrid working machine is controlled to stop operation based on the specific content of the control signal.

[0063] For example, if the control signal indicates that the button has been pressed m times consecutively within t2 seconds, the control signal indicates that a power stop operation is to be executed. Here, t2 can be the same as t1, but m and n can be different. For example, if the button is pressed three times consecutively within 1 second, the control signal indicates that the hybrid working machine is to be powered off. Consequently, the hybrid working machine's power output is stopped.

[0064] It should be noted that the specific control signal representation method can also be other. As long as the corresponding power switching instruction or power stop instruction can be accurately obtained according to the control signal, the hybrid working machine can be controlled to perform the corresponding power switching operation or power stop operation.

[0065] 104. When it is detected that the control signal indicates that the operation has continued for a third preset time period, control the hybrid working machine to perform a power acceleration operation.

[0066] Similarly, after obtaining the control signal, through analysis and processing of the control signal, it is determined that the control signal indicates continuous operation for the third preset time period, indicating that the content of the control signal at this time is a power acceleration operation, so the hybrid working machine is controlled to perform the power acceleration operation.

[0067] For example, after analyzing the control signal, it is found that the control signal indicates that the button has been pressed for t3 seconds, which may be 1 second. This indicates that the control instruction represented by the control signal at this time is to perform a power acceleration operation, thereby controlling the hybrid operating machine to perform power acceleration.

[0068] Similar to the power switching and power stop mentioned above, the control signal can also be in other forms. As long as the corresponding control signal indicating power acceleration can be detected, the power acceleration operation will be performed. Whether it is power acceleration or the power switching and power stop mentioned above, the specific form of the control signal does not constitute a specific limitation. As long as the same principle is adopted, the control between powers achieved by a control button falls within the scope of protection of the present invention.

[0069] In addition, it should be pointed out that there is no logical order relationship between steps 102, 103 and step 104 in this embodiment, and the three are parallel methods.

[0070] The present embodiment provides a power control method for a hybrid working machine, which obtains a control signal of a power control structure, where the power control structure is an independent control structure arranged on the hybrid working machine; when it is detected that the control signal indicates a first preset number of intermittent operations within a first preset time period, the hybrid working machine is controlled to switch between the engine working state and the motor working state; when it is detected that the control signal indicates a second preset number of intermittent operations within a second preset time period, the hybrid working machine is controlled to stop working; when it is detected that the control signal indicates a third preset time period of continuous operation, the hybrid working machine is controlled to perform a power acceleration operation. Since the power switching, start-stop and acceleration control are realized by the independent control structure, compared with the coordinated operation of the cab and the control room, only different operating methods need to be implemented on the independent control structure, which simplifies the operator's operating process and effectively improves the operating efficiency of the working machine.

[0071] Figure 2 It is a schematic diagram of the power switching process provided by an embodiment of the present invention.

[0072] like Figure 2 As shown, in this embodiment, controlling the hybrid working machine to switch between the engine working state and the motor working state mainly includes the following steps, which are the specific implementation process of step 102 in the above embodiment:

[0073] 201. Detect a current first power state of the hybrid operating machine.

[0074] Specifically, when it is detected that the control signal indicates intermittent operation for a first preset number of times within a first preset duration, i.e., after the control signal indicates execution of the power switching command, the current first power state of the hybrid working machine is detected, that is, the power output state type of the hybrid working machine at that time is determined. The first power state includes the engine operating state and the motor operating state.

[0075] 202. If the current first power state is the engine working state, switch the engine working state to the motor working state.

[0076] After analyzing the hybrid working machine's current first power state, it is determined that the current first power state is the engine operating state, meaning that the working machine's power output is currently fueled to power the engine, thereby enabling the working machine to operate. The current power output mode is then switched to the motor operating state. The specific switching method is not described in detail in this embodiment and can be understood by referring to the power switching methods of existing hybrid working machines.

[0077] 203. If the current first power state is the motor working state, switch the motor working state to the engine working state.

[0078] Similarly, when the first power state is detected as the motor operating state, that is, the current power output is electrical energy output, the power output mode is switched from the motor operating state to the engine operating state, thereby achieving power switching. Again, the specific switching process will not be explained in detail, and can be understood by referring to the switching methods of existing hybrid working machines.

[0079] 204. If the current first power state indicates an unpowered working state, control the working state of the hybrid working machine to switch to an engine working state or a motor working state.

[0080] Similarly, after detecting the current first power state of the hybrid working machine, the method further includes controlling the hybrid working machine to start power output when the current first power state is analyzed and determined to be in a non-powered operating state, that is, when both the engine and the motor of the hybrid working machine are currently activated. Specifically, the non-powered operating state is switched to an engine operating state or a motor operating state, so that the hybrid working machine is in a power output state. In this embodiment, the motor operating state is preferentially selected for the startup process to reduce fuel consumption and better meet environmental requirements.

[0081] Similarly, step 202, step 203 and step 204 are also parallel processes, and the specific order is not distinguished.

[0082] Figure 3 It is a schematic diagram of the power start-stop process provided by an embodiment of the present invention.

[0083] like Figure 3 As shown, based on the above embodiment, controlling the hybrid working machine to stop working in this embodiment mainly includes the following steps, which are the specific implementation process of step 103 in the above embodiment:

[0084] 301. Detect a current second power state of the hybrid operating machine.

[0085] When it is detected that the control signal indicates a second preset number of intermittent operations within a second preset time period, that is, when the control signal is analyzed and it is determined that the control signal is to perform a power start-stop operation, the current second power state of the hybrid working machine is first detected to determine whether the hybrid working machine is in an operating state or a stopped state, thereby better achieving power control of the hybrid working machine.

[0086] 302. If the current second power state is the engine operating state, control the engine to stop operating.

[0087] When the current second power state is detected and it is determined that the current second power state is the engine working state, the engine is controlled to stop working, so that the power output of the hybrid working machine is zero, that is, the no-power working state.

[0088] 303. If the current second power state is the motor working state, control the motor to stop working.

[0089] When the current second power state is detected and it is determined that the current second power state is the motor working state, the motor is controlled to stop working, so that the power output of the hybrid working machine is zero, that is, the no-power working state.

[0090] Generally speaking, when a control signal indicating a power start / stop command is detected, the current power mode of the hybrid working machine is detected. Regardless of the power output mode, the current power output must be stopped, so that the hybrid working machine is in a non-power output state. If the second power output state is detected, indicating that both the engine and the motor are not operating, that is, the working machine is in a non-powered state, power output is activated. Similarly, either the engine or the motor can be activated, with the motor being the preferred mode.

[0091] Similar to the above embodiment, regardless of whether the control signal indicates power switching or power start / stop control, if the hybrid working machine is detected to be in a non-power output state, the hybrid working machine is first started in motor-powered mode, and then subsequent operations are performed. Furthermore, in this embodiment, steps 302 and 303 are executed in parallel, regardless of their specific order.

[0092] Figure 4 It is a schematic diagram of the process of power acceleration provided by an embodiment of the present invention.

[0093] like Figure 4 As shown, based on the above embodiment, controlling the hybrid working machine to perform a power acceleration operation in this embodiment mainly includes the following steps, which are the specific implementation process of step 104 in the above embodiment:

[0094] 401. Detect a current third power state of the hybrid operating machine.

[0095] Specifically, when it is detected that the control signal of the hybrid working machine indicates continuous operation for the third preset time period, that is, when a power acceleration operation needs to be performed, the current third power state of the hybrid working machine is first determined to determine whether it is currently in the engine power output state or the motor power output state, so as to more accurately achieve power acceleration control.

[0096] 402. If the current third power state is the engine working state, control the engine to perform a speed acceleration operation.

[0097] When the analysis of the current third power state indicates that the current third power state represents the engine working state, the engine is controlled to perform a power acceleration operation. The specific process of the engine performing the power acceleration operation will not be described in detail, and it can be a method of increasing the throttle, etc.

[0098] 403. If the current third power state is the motor working state, control the motor to perform a speed acceleration operation.

[0099] Similarly, when the analysis of the current third power state indicates that the current third power state represents the motor working state, the motor is controlled to perform a power acceleration operation. The specific process of the motor performing the power acceleration operation is also not described in detail, and it can be a method of increasing current, etc.

[0100] Generally speaking, after analyzing the control signal to determine whether a power acceleration operation is to be performed, the current power output form is first determined, and then the corresponding power acceleration strategy is executed based on the current power output form.

[0101] 404. Detect whether the control signal maintains continuous operation.

[0102] 405. If so, control the engine or motor to continuously perform the speed acceleration operation.

[0103] 406. If not, control the engine or motor to stop executing the speed acceleration operation.

[0104] After the power acceleration operation is completed, the control signal is continuously detected. If the control signal is detected to maintain the power acceleration instruction, the corresponding key is determined to be in a continuously pressed state. If so, the engine or motor is controlled to continue the corresponding power acceleration operation. Otherwise, the corresponding engine or motor is controlled to stop the power acceleration operation. In other words, if the operator continues to press the key, the power output speed will continue to increase regardless of whether the engine power output or the motor power output is currently being output. If the operator stops pressing the key during the power acceleration process, the power acceleration operation will be stopped.

[0105] Specifically, controlling the engine or motor to continuously perform the speed acceleration operation may include first detecting a current acceleration working state, and if the current acceleration working state indicates an engine acceleration working state, then continuing to perform the engine power acceleration operation. Similarly, if the current acceleration working state indicates a motor acceleration working state, then continuing to perform the motor power acceleration operation.

[0106] Based on the same principle, the specific control of the engine or motor to stop executing the speed acceleration operation may include: controlling and detecting the current acceleration working state of the hybrid working machine; if the current acceleration working state is the engine speed increasing state, controlling the engine to stop executing the speed increasing operation; if the current acceleration working state is the motor speed increasing state, controlling the motor to stop executing the speed increasing operation.

[0107] In detail, whether it is to control the execution of continuous power acceleration operation or the execution of the power acceleration stop operation, it is necessary to first determine the current power acceleration state, that is, to determine whether the current state is engine power acceleration or motor power acceleration, so as to achieve corresponding control more accurately.

[0108] To illustrate from the operator's perspective, the operator controls the power of the hybrid working machine through an independent control button according to actual work needs. First, the hybrid working machine can be started by pressing the button twice (the first preset number of times) or three times (the second preset number of times) in a row. Then, if power switching is required, press the button twice in a row to switch between the powers. If acceleration is required, press and hold the button for a third preset time. The button is always in the pressed state, and the hybrid working machine is always in the power acceleration state. Then release the button and stop the power acceleration. If you need to stop the work of the working machine, press the button three times in a row to stop the power output of the hybrid working machine. It should be noted that the button is used as an example in this embodiment. In actual applications, it can also be implemented by structures such as outrigger throttles. The same principle applies.

[0109] The present invention achieves simple control of the engine and motor with a single button, making it easy for the operator to operate. It also allows the existing outrigger throttle button switch to be reused without any additional cost, effectively improving the operating efficiency of the machine.

[0110] Based on the same general inventive concept, the present invention also protects a power control device for a hybrid working machine. The power control device for the hybrid working machine provided by the present invention is described below. The power control device for the hybrid working machine described below and the power control method for the hybrid working machine described above can be referenced to each other.
