The invention discloses an execution and lubrication two-in-one electronic oil pump control method. The method comprises the steps that S1, a vehicle power system is activated; s2, PID closed-loop control is carried out on the flow of the lubricating pressure rising and maintaining oil duct; s3, the BLDC motor control unit MCU judges the pressure of an oil duct driven by a current BLDC motor through a feedback signal provided by a pressure sensor, when the pressure of the oil duct is smaller than a first pressure threshold P0, the step S4 is executed, when the pressure of the oil duct is larger than or equal to the first pressure threshold P0, the step S5 is executed, and the pressure of the first pressure threshold P0 is lower than the half-linkage pressure of the clutch; s4, an oil channel oil charging strategy; s5, performing pressure closed-loop control; s6, clutch separation control; according to the invention, the execution mechanism and the cost of the hybrid gearbox are reduced, and the requirements of shaft system lubrication and clutch clutching are met at the same time.

    本发明公开了一种执行和润滑二合一的电子油泵控制方法,S1,车辆动力系统激活;S2,润滑起压保压油道流量PID闭环控制;S3,BLDC电机控制单元MCU通过压力传感器提供的反馈信号判断当前BLDC电机驱动的油道压力,当油道压力小于第一压力阈值P0时执行步骤S4,当油道压力大于等于第一压力阈值P0时执行步骤S5,其中第一压力阈值P0压力比离合器半联动压力低;S4,油道充油策略;S5,压力闭环控制;S6,离合器分离控制;本发明实现了减少混动变速箱的执行机构及成本,同时满足轴系润滑和离合器离合的要求。
