Abstract

The present invention provides an oil pump control method, device and oil pump, comprising: calculating the target flow of the oil pump according to the rotation speed of the steering wheel; calculating the target displacement of the oil pump according to the rotation speed of the engine and the target flow; The target displacement adjusts the eccentricity of the oil pump so that the actual displacement of the oil pump reaches the target displacement. According to an oil pump control method and device and an oil pump according to an embodiment of the present invention, the displacement of the oil pump can be adjusted not only according to the rotational speed of the engine, but also according to the rotational speed of the steering wheel, so that the steering wheel When rotating, the oil pump displacement can also be increased to reduce the oil temperature of the system.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to a method and device for controlling an oil pump and the oil pump. Background technique [0002] The existing steering oil pump is a fixed-displacement oil pump. In order to meet the fastest rotation requirement of the steering wheel under idling state, it is necessary to increase the displacement of the steering pump. However, as the engine speed increases, the compressed high-pressure oil increases, consumes more energy, and converts more heat, resulting in high system temperature. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a method for controlling the oil pump, which can adjust the displacement of the oil pump according to the engine speed and the steering wheel speed, thereby reducing ...
