Detailed Description
The PTO clutch belongs to a power take-off, typically in driving connection with the drive shaft of the engine, so as to transmit the power of the engine to a machine (e.g. an agricultural implement), which may be attached to or towed behind the 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 rotation speed of the engine needs to be increased to provide a larger torque during the coupling of the engine and the PTO clutch, so that the engine and the PTO clutch are successfully coupled. In the related art, the speed of the engine is typically adjusted by the personal experience of the driver to ensure that the PTO clutch is successfully engaged with the engine. However, the method of relying solely on driver speed regulation is not reliable and does not ensure successful engagement of the engine with the PTO clutch.
In view of the above, embodiments of the present invention provide a method and an apparatus for controlling a PTO clutch, and a computer program product, where the method for controlling the PTO clutch includes: controlling the engine to operate at a first speed in response to the combined command; acquiring the required torque of the PTO clutch; judging whether the engine and the PTO clutch are successfully combined or not; and 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. Compared with the prior art that the rotating speed of the engine is adjusted by depending on personal experience of a driver, the embodiment of the invention adjusts the rotating speed of the engine through the required torque of the PTO clutch, and is beneficial to improving the combination effect of the PTO clutch and the engine.
While various alternative implementations of the present invention will now be described with reference to the drawings, it will be understood by those skilled in the art that the following implementations are illustrative only and not exhaustive, and that certain features or certain examples may be substituted, spliced or combined by those skilled in the art based on these implementations, and are still considered to be the present disclosure.
Referring to fig. 1, a method for controlling a PTO clutch according to an embodiment of the present invention includes the steps of:
and S101, controlling the engine to run at a first rotating speed in response to the combination instruction.
The first rotating speed is the set rotating speed of the engine. The PTO clutch comprises a PTO shaft, and when the engine runs at the set rotating speed, the engine can transmit torque and torque to the PTO clutch so that the rotating speed of the engine can be kept at the set rotating speed.
S102, acquiring the required torque of the PTO clutch.
In this embodiment, the step of acquiring the required torque of the PTO clutch may include: and acquiring the required pressure of the PTO clutch and the speed difference between two ends of the PTO clutch, and acquiring the required torque according to the required pressure and the speed difference.
Wherein the required pressure of the PTO clutch is the set pressure. And the two ends of the PTO clutch are respectively provided with a speed detection device for detecting the rotating speeds of the two ends of the PTO clutch, and the speed difference of the two ends of the PTO clutch can be obtained according to the rotating speeds of the two ends. In one specific implementation, the specific formula for obtaining the required torque according to the difference between the required pressure and the speed is as follows:
N＝max(V*P*μ)；
n is the required torque, V is the speed difference, P is the required pressure, mu is a first parameter, the first parameter can be obtained through multiple experiments according to the characteristic of the clutch, and the value range of mu is 0.5-2.5.
In some other embodiments, a plurality of experimental measurements may be performed, a graph relating to the speed difference, the demand pressure and the demand torque is obtained through statistics, and the corresponding demand torque is obtained by searching the graph according to the speed difference and the demand pressure.
S103, judging whether the engine and the PTO clutch are successfully combined.
The engine is also in transmission connection with a machine, which may include an agricultural implement such as a dado implement, for example. When the mechanical load is large, the PTO shaft of the PTO clutch is liable to fail to be engaged with the drive shaft of the engine, resulting in disengagement of the PTO shaft 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 rotation speed of the PTO clutch can be acquired by searching for the universal characteristic curve of the engine. It should be noted that 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 used as an abscissa, the torque of the engine is used 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 the universal characteristic curve of the engine, it is also advantageous to avoid abnormal operation of the engine during the coupling process of the PTO clutch and the engine.
The step of obtaining the second rotation speed according to the required torque after obtaining the required rotation speed of the PTO clutch may further include: and acquiring 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 demanded speed and the preset value is equal to the second speed. To improve the reliability of the engagement of the engine with the PTO clutch, the demanded speed is typically further increased to obtain a second speed to ensure that the rotation of the engine can be successfully engaged with the PTO clutch. In a specific implementation manner, a specific formula for obtaining 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 predetermined value may range from 50rpm to 150 rpm. For example, the preset value may be 50rpm, 100rpm or 150rpm, thereby further improving the coupling effect of the engine and 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 speed in response to the combined command; acquiring the required torque of the PTO clutch; judging whether the engine and the PTO clutch are successfully combined or not; and 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. Compared with the prior art that the rotating speed of the engine is adjusted by depending on personal experience of a driver, the rotating speed of the engine is adjusted by the aid of the required torque of the PTO clutch, human errors in the combining process are reduced, and the combining effect of the PTO clutch and the engine is improved.
Furthermore, the rotating speed of the engine is adjusted according to the torque required by the PTO clutch in the combining process, the actual load requirement in the combining 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 adjusted through the required torque of the PTO clutch, 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. S202, if the combination of the engine and the PTO clutch fails, whether the current vehicle parameters meet the requirement that the PTO clutch works normally is judged.
Wherein, after controlling the engine to operate at the second speed, if the engine fails to engage the PTO clutch, there may be the following two situations. In one possible embodiment, current vehicle parameters may not be sufficient for proper operation of the PTO clutch, resulting in a failure of the engine to engage the PTO clutch. In another possible implementation, the current overall vehicle parameters may be such that the PTO clutch is functioning properly, but the second rotational speed at which the engine is operating is still not sufficient to meet the engagement requirements.
In this embodiment, determining whether the current vehicle parameters satisfy the normal operation of the PTO clutch includes: and judging whether the working torque of the engine running at the second rotating speed is the maximum torque or not. Here, "maximum torque" refers to a torsional moment of the engine crankshaft. And if the working torque is the maximum torque, determining that the current vehicle parameters cannot meet the normal work of the PTO clutch. After the current vehicle parameters can not meet the normal work of the PTO clutch, the method also comprises the following steps: and S301, replacing the finished automobile with other parameters. The current whole vehicle can not work as a whole, and the whole vehicle can be replaced by other whole vehicles which can meet the normal work of the PTO clutch.
And if the working torque is smaller than the maximum torque, determining that the current vehicle parameters can meet the requirement of normal work of the PTO clutch, and at the moment, continuously adjusting the rotating speed of the engine. Continuing to adjust the rotational speed of the engine, comprising: and S203, reacquiring the second required torque of the PTO clutch, acquiring 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 worth mentioning that reacquiring the second requested torque of the PTO clutch may include: and acquiring a second required pressure of the PTO clutch and a second speed difference between two ends of the PTO clutch again, and acquiring a second required torque according to the second required pressure and the second speed difference which are acquired again. The specific implementation manner of obtaining the second required torque may be the same as that in the above embodiment, and is not described herein again. Further, a new second rotation speed is obtained according to the second required torque, and the specific implementation manner of the new second rotation speed may be the same as that in the foregoing embodiment, and is not described herein again.
In this embodiment, after controlling the engine to operate at the second rotation speed, the method may further include: it is determined whether the engine and PTO clutch are successfully engaged. If the engine is successfully engaged with the PTO clutch, the first speed is replaced with a second speed in a subsequent control of the engine to operate at the first speed.
For example, during the subsequent operation of the engine, when the set rotation speed of the engine is the first rotation speed, the first rotation speed is replaced by the second rotation speed, and the engine runs at the second rotation 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 engaged, the method further includes the steps of: and S401, controlling the rotation speed of the engine to be recovered from the second rotation speed to the first rotation speed. The rotating speed of the engine is recovered from the second rotating speed to the first rotating speed, so that the operation process of the engine at the second rotating speed is only applied to the combination process, the rotating speed of the engine can be kept at the first rotating speed after combination, the operation rotating speed of the engine after combination is not adjusted, and the abnormal operation of the engine is further avoided.
