Problems solved by technology

[0003] During the operation of the appliance, the pressure control of the engagement of the PTO clutch is usually achieved through closed-loop control. However, with the existing technology, it is easy to cause the invalid engagement of the PTO clutch due to the driver's misoperation, resulting in clutch wear

Abstract

The invention provides a control method and device for a power take-off device PTO clutch, and the method comprises the steps: obtaining the running state of a whole vehicle in response to a combination instruction; judging whether the running state of the whole vehicle meets a combination condition or not; if yes, applying pressure to a PTO clutch according to a first pressure applying strategy, and detecting the state of a PTO shaft; when it is detected that the PTO shaft rotates, applying pressure to the PTO clutch according to a second pressure applying strategy so that the PTO clutch can be combined, wherein the pressure increasing speed of the second pressure applying strategy is greater than the pressure increasing speed of the first pressure applying strategy; in the process of applying pressure to the clutch according to the second pressure applying strategy, whether the speed difference change rate between the PTO shaft and the engine is abnormal or not is detected in real time; and when it is detected that the speed difference change rate is abnormal, the pressure applied to the clutch is adjusted, and thus the speed difference change rate is in a normal state. The wear of the PTO clutch can be reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a control method and device for a PTO clutch of a power output device. Background technique [0002] Power take-offs are commonly used in vehicles, such as tractors and trucks, to provide power from the vehicle's engine to machinery, such as agricultural implements, which may be attached to the vehicle or towed behind the vehicle. For example, in agricultural applications, tractors may pull implements (eg, cultivators, seeders, harvesters, etc.) across a field to perform agricultural tasks. The PTO can be coupled to the vehicle's engine (eg, via a drive shaft) to provide power to the appliance. The PTO may include a PTO clutch to couple and decouple the PTO shaft and the drive shaft. [0003] During the operation of the appliance, the closed-loop control is usually used to realize the pressure control of the engagement of the PTO clutch. However, using the existing techn...
