Detailed Description
PTO clutches are power take-off devices that are typically drivingly connected to the drive shaft of an engine to transfer the power of the engine to a machine (e.g., an agricultural implement) that may be attached to or towed behind the entire vehicle. In the related art, when the mechanical load is large, the coupling failure of the engine and the PTO clutch is easily caused, and at this time, the rotational speed of the engine needs to be adjusted to be high, so that a larger torque is provided during the coupling process of the engine and the PTO clutch, and the engine and the PTO clutch are successfully coupled. In the related art, the rotational speed of the engine is typically adjusted by means of personal experience of the driver to ensure successful engagement of the PTO clutch with the engine. However, the method of purely relying on the driver's speed adjustment is not reliable and does not ensure successful engagement of the engine with the PTO clutch.
In view of this, an embodiment of the present invention provides a method and apparatus for controlling a PTO clutch, and a computer program product, where the method for controlling a PTO clutch includes: controlling the engine to operate at a first rotational speed in response to the combined command; acquiring a required torque of a PTO clutch; judging whether the engine and the PTO clutch are successfully combined; if the combination of the engine and the PTO clutch fails, a second rotating speed is obtained according to the required torque, and the engine is controlled to operate at the second rotating speed. Compared with the prior art that the rotation speed of the engine is regulated by the personal experience of a driver, the embodiment of the invention regulates the rotation speed of the engine through the required torque of the PTO clutch, thereby being beneficial to improving the combination effect of the PTO clutch and the engine.
While several alternative implementations of the invention are described below in conjunction with the drawings, it will be understood by those skilled in the art that the implementations described below are illustrative only and are not an exhaustive list, and that certain features or certain examples may be substituted, combined, or combined by those skilled in the art on the basis of these implementations, which are still to be regarded as the disclosure of the invention.
Referring to fig. 1, the control method of the PTO clutch provided by the embodiment of the present invention includes the following steps:
s101, responding to the combination instruction, and controlling the engine to run at a first rotation speed.
The first rotation speed is the set rotation speed of the engine. The PTO clutch includes a PTO shaft that is in driving engagement with a drive shaft of the engine, and the engine is capable of transmitting torque and torque to the PTO clutch to maintain the rotational speed of the engine at a set rotational speed when the engine is operating at the set rotational speed.
S102, acquiring the required torque of the PTO clutch.
In this embodiment, the step of obtaining the required torque of the PTO clutch may include: the method comprises the steps of obtaining the required pressure of the PTO clutch and the speed difference between two ends of the PTO clutch, and obtaining the required torque according to the required pressure and the speed difference.
The required pressure of the PTO clutch is the set pressure. The speed detection devices are respectively arranged at the two ends of the PTO clutch and are used for detecting the rotating speeds at the two ends of the PTO clutch, and the speed difference at the two ends of the PTO clutch can be obtained according to the rotating speeds at the two ends. In one specific implementation, the specific formula for obtaining the required torque from the required pressure and rate difference is:
N＝max(V*P*μ)；
wherein N is the required torque, V is the speed difference, P is the required pressure, mu is the first parameter, the first parameter can be obtained through multiple experiments according to the clutch characteristics, and the value range of mu is 0.5-2.5.
In some other embodiments, multiple experimental measurements may be performed to statistically obtain graphs of the speed difference, the required pressure, and the required torque, and the corresponding required torque may be obtained by searching the graphs according to the speed difference and the required pressure.
S103, judging whether the engine and the PTO clutch are successfully combined or not.
The engine is also in driving connection with a machine, which may for example comprise an agricultural implement such as a dawn implement. When the mechanical load is large, the PTO shaft of the PTO clutch is liable to fail to be coupled with the drive shaft of the engine, resulting in the PTO shaft being disengaged from the drive shaft.
Conversely, when the PTO shaft is mechanically coupled to the drive shaft, the PTO clutch is successfully engaged with the engine. If the PTO clutch is successfully combined with the engine, the engine can drive the machine to work, and the rotating speed of the engine can be kept at the first rotating speed.
And S104, if the combination of the engine and the PTO clutch fails, obtaining a second rotating speed according to the required torque, and controlling the engine to operate at the second rotating speed.
In this embodiment, the step of obtaining the second rotation speed according to the required torque may include: and acquiring the required rotating speed of the PTO clutch according to the required torque.
In this embodiment, the required rotational speed of the PTO clutch may be obtained by looking up a universal characteristic of the engine. The universal characteristic curve of the engine is also called a load curve, a universal characteristic curve or a propeller curve, wherein the rotation speed of the engine is taken as an abscissa, the torque of the engine is taken as an ordinate, and the torque corresponding to the engine under each specific torque can be read according to the universal characteristic curve.
Further, since the required rotational speed of the PTO clutch is obtained based on a general characteristic curve of the engine, it is also advantageous to avoid abnormal operation of the engine during the coupling of the PTO clutch and the engine.
After the required rotational speed of the PTO clutch is obtained, the step of obtaining the second rotational speed from the required torque may further include: and obtaining a second rotating speed according to the required rotating speed and a preset value.
In this embodiment, the step of obtaining the second rotation speed according to the required torque and the preset value may include: the sum of the required rotation speed and the preset value is equal to the second rotation speed. To increase the reliability of the coupling of the engine to the PTO clutch, the required rotational speed is typically further increased to achieve a second rotational speed to ensure that the rotation of the engine is successfully coupled to the PTO clutch. In a specific implementation manner, a specific formula for acquiring the second rotation speed according to the required rotation speed and the preset value is as follows:
V2＝V+C；
wherein V2 is the second rotation speed, V is the required rotation speed, and C is the preset value.
It is noted that the preset value may range from 50rpm to 150rpm. For example, the preset value may be 50rpm, 100rpm, or 150rpm, thereby further improving the coupling effect of the engine to the PTO clutch.
The embodiment of the invention provides a control method of a PTO clutch, which comprises the following steps: controlling the engine to operate at a first rotational speed in response to the combined command; acquiring a required torque of a PTO clutch; judging whether the engine and the PTO clutch are successfully combined; if the combination of the engine and the PTO clutch fails, a second rotating speed is obtained according to the required torque, and the engine is controlled to operate at the second rotating speed. Compared with the prior art that the rotation speed of the engine is regulated by the personal experience of a driver, the embodiment of the invention regulates the rotation speed of the engine through the required torque of the PTO clutch, reduces human errors in the combining process, and is beneficial to improving the combining effect of the PTO clutch and the engine.
Further, according to the torque required by the PTO clutch in the combination process, the rotating speed of the engine is regulated, the actual load requirement in the combination process can be fed back, the abrasion of the PTO clutch is reduced, and the service life of the PTO clutch is prolonged. Meanwhile, the rotating speed of the engine is regulated through the torque required by the PTO clutch, so that the requirement on a driver in the working process is reduced, and the operation difficulty is reduced.
Referring to fig. 2, in the present embodiment, after controlling the engine to operate at the second rotation speed, the following steps may be further included: s201, judging whether the engine and the PTO clutch are successfully combined. And S202, if the combination of the engine and the PTO clutch fails, judging whether the current whole vehicle parameters meet the normal work of the PTO clutch.
After the engine is controlled to operate at the second rotational speed, if the engine fails to engage with the PTO clutch, the following two cases may exist. In one possible embodiment, the current vehicle parameters may not be sufficient for the PTO clutch to function properly, resulting in failure of the engine to engage the PTO clutch. In another possible implementation, the current vehicle parameters may satisfy the PTO clutch operating normally, but the second rotational speed of engine operation still fails to satisfy the coupling requirement.
In this embodiment, determining whether the current overall vehicle parameter satisfies normal operation of the PTO clutch includes: and judging whether the working torque of the engine operated at the second rotating speed is the maximum torque. Here, "maximum torque" refers to the torque of the engine crankshaft. If the working torque is the maximum torque, determining that the current whole vehicle parameters cannot meet the requirement of normal working of the PTO clutch. After the current whole vehicle parameters can not meet the normal work of the PTO clutch, the method further comprises the following steps: s301, replacing the whole vehicle with other parameters. The existing whole vehicle cannot work and should be replaced by other whole vehicles capable of meeting the normal work of the PTO clutch.
If the working torque is smaller than the maximum torque, the current whole vehicle parameter is determined to be capable of meeting the normal working of the PTO clutch, and at the moment, the rotating speed of the engine needs to be continuously adjusted. Continuing the step of adjusting the rotational speed of the engine, comprising: s203, re-acquiring the second required torque of the PTO clutch, obtaining a new second rotating speed according to the second required torque, and controlling the engine to operate at the new second rotating speed.
It is noted that the re-acquiring the second requested torque of the PTO clutch may include: and re-acquiring a second required pressure of the PTO clutch and a second speed difference between two ends of the PTO clutch, and acquiring a second required torque according to the re-acquired second required pressure and the second speed difference. The specific implementation manner of obtaining the second required torque may be the same as that in the foregoing embodiment, and will not be described herein again. Further, the new second rotation speed is obtained according to the second required torque, and the specific implementation manner thereof may be the same as that in the above embodiment, and will not be described herein.
In this embodiment, after controlling the engine to operate at the second rotation speed, the method may further include: and judging whether the engine and the PTO clutch are successfully combined or not. If the combination of the engine and the PTO clutch is successful, the first rotating speed is replaced by the second rotating speed when the engine is controlled to operate at the first rotating speed subsequently.
For example, in the working process of the subsequent engine, when the set rotating speed of the engine is the first rotating speed, the first rotating speed is replaced by the second rotating speed, and the engine runs at the second rotating speed, so that the combination effect of the engine and the PTO clutch is improved.
In this embodiment, after the engine and the PTO clutch are successfully combined, the method further includes the following steps: s401, controlling the rotation speed of the engine to return from the second rotation speed to the first rotation speed. The rotation speed of the engine is recovered from the second rotation speed to the first rotation speed, so that the operation process of the engine at the second rotation speed is only applied to the combination process, the rotation speed of the engine after combination can be kept at the first rotation speed, the operation rotation speed of the engine after combination can not be regulated, and abnormal operation of the engine can be further avoided.

Wherein the memory 20 is configured to store a computer program and the processor 10 is configured to execute the computer program stored in the memory 20 to implement the control method of the PTO clutch as in any of the embodiments described above. Compared with the prior art that the rotation speed of the engine is regulated by the personal experience of a driver, the control method of the PTO clutch regulates the rotation speed of the engine through the required torque of the PTO clutch, reduces human errors in the combining process, and is beneficial to improving the combining effect of the PTO clutch and the engine.
