Embodiment 1

[0027] Figure 1A It is a flowchart of a method for controlling a drive axle assembly provided according to the first embodiment. This embodiment can be applied to the case of controlling the drive axle assembly. The method can be executed by a drive axle assembly control device. The bridge assembly control device can be implemented in the form of hardware and / or software, and can be integrated into the electronic equipment running the system.

[0028] like Figure 1A As shown, the method includes:

[0029] S110. Collect lubricating oil parameters, actual input torque and actual input rotational speed of the target drive axle assembly.

[0030] The target drive axle assembly refers to the drive axle assembly to be controlled. It can be known that the drive axle assembly has become one of the four major assemblies of the car, and the drive axle assembly includes the final gear and the differential. The drive axle assembly is used to reduce the speed and increase the torque of...

Embodiment 2

[0051] figure 2 It is a flowchart of a method for controlling a drive axle assembly provided according to the second embodiment. This embodiment is further optimized on the basis of the above-mentioned embodiment. Specifically, for the operation "According to the reference input torque and the reference input speed, the actual input torque and the actual input speed of the target drive axle assembly are respectively performed. Adjust" to refine.

[0052] like figure 2 As shown, the method includes:

[0053] S210. Collect lubricating oil parameters, actual input torque and actual input rotational speed of the target drive axle assembly.

[0054] S220. Input the lubricating oil parameters as input data into a pre-trained drive axle assembly control model, and determine a reference input torque and a reference input rotational speed through the drive axle assembly control model.

[0055] S230. Compare the reference input torque with the actual input torque of the target dri...

Embodiment 3

[0069] image 3 It is a flow chart of a method for controlling a drive axle assembly provided according to the third embodiment. This embodiment is further optimized on the basis of the above-mentioned embodiment. Specifically, the embodiment of the present application provides a training method for a control model of a drive axle assembly.

[0070] like image 3 As shown, the method includes:

[0071] S310. Obtain historical lubricating oil parameters of the drive axle assembly and historical input torque and historical input rotational speed corresponding to the historical lubricating oil parameters.

[0072]Among them, the historical input torque and historical input speed correspond to historical lubricating oil parameters, and the historical lubricating oil parameters of the drive axle assembly and the corresponding historical input torque and historical input speed are used to construct model training samples. The historical input torque, and the corresponding histori...

Abstract

The embodiment of the invention discloses a drive axle assembly control method and device, a medium and electronic equipment. The method comprises the steps that lubricating oil parameters, actual input torque and actual input rotating speed of a target drive axle assembly are collected; the lubricating oil parameters serve as input data and are input into a pre-trained drive axle assembly control model, and a reference input torque and a reference input rotating speed are determined through the drive axle assembly control model; and according to the reference input torque and the reference input rotating speed, the actual input torque and the actual input rotating speed of the target drive axle assembly are adjusted. According to the technical scheme, the control effectiveness of the target drive axle assembly can be improved, and the performance of the target drive axle assembly is brought into full play.

Description

technical field [0001] The present invention relates to the technical field of computer application, and in particular, to a control method, device, medium and electronic device of a drive axle assembly. Background technique [0002] The drive axle assembly is the last assembly in the vehicle transmission system. The drive axle assembly is used to reduce the speed and increase the torque from the engine power from the universal transmission, and change the direction of the power transmission to make the vehicle run. Reasonable control of the drive axle assembly to give full play to the performance of the drive axle assembly is of great significance to ensure the performance of the vehicle. [0003] In the related art, most of the transfer cases are used to set the theoretical maximum input torque for the drive axle assembly, and the actual input torque of the drive axle assembly is limited to not exceed the maximum input torque. However, the above-mentioned related technolo...
