Abstract

The invention relates to a method, a device, a control device and a storage medium for main oil pressure regulation, which are applied in the technical field of hybrid vehicles. The method includes: obtaining the working condition that the vehicle needs to enter; obtaining the main oil pressure corresponding to the working condition as the target main oil pressure; the main oil pressure is the oil pressure of the main hydraulic oil circuit of the hydraulic system; obtaining the main oil pressure oil The actual main oil pressure of the main oil circuit; calculate the difference between the actual main oil pressure and the target main oil pressure; adjust the control current of the solenoid valve in the main oil pressure oil circuit according to the difference, so as to adjust the main oil pressure. The embodiment of the invention solves the problem of hysteresis in oil pressure regulation, and the control method is simple and effective, which can reduce unnecessary pressure waste in the main oil pressure circuit of the hydraulic system.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a method, a device, a control device and a storage medium for regulating main oil pressure of a hybrid electric vehicle. Background technique [0002] A hybrid vehicle refers to a vehicle equipped with two or more power sources. Currently, a hybrid vehicle generally refers to a vehicle equipped with an engine and a drive motor. The engine consumes fuel, and the drive motor consumes electric energy from the battery. Hybrid power means that the car uses fuel drive and electric drive. Generally, when the vehicle starts and stops, it is only driven by the motor. The engine does not work until it reaches a certain speed. Working status. In a hybrid electric vehicle, the power of the engine and the driving motor is coupled and output through the power coupling system, and the performance of the power coupling system is directly related to the performance of the hybrid...
