The invention discloses a control method and system for a new energy double-source steering oil pump. The method comprises the steps that when a vehicle normally runs, a high-pressure oil pump system breaks down, and a high-pressure oil pump stops working, if the vehicle meets the working condition of a low-pressure oil pump, a low-pressure oil pump controller controls a low-pressure oil pump motor to work according to working enabling of the low-pressure oil pump; the low-pressure oil pump controller feeds back the working state of the low-pressure oil pump When the vehicle runs normally, the vehicle control unit judges whether the vehicle meets the working recovery condition of the high-pressure oil pump or not; and when the vehicle meets the high-pressure oil pump recovery working condition, the high-pressure oil pump controller controls the high-pressure oil pump motor to recover working according to the high-pressure oil pump recovery enabling. The low-pressure oil pump can continuously keep the normal working state when the high-pressure oil pump breaks down, after the high-pressure oil pump system breaks down, the low-pressure oil pump is controlled to stop working, the high-pressure oil pump system is switched to continue working, and normal working of a vehicle steering system is guaranteed.

    本发明公开了一种新能源双源转向油泵的控制方法及控制系统。该方法包括:车辆正常运行时,当高压油泵系统出现故障,高压油泵停止工作时,若车辆满足低压油泵工作条件,低压油泵控制器根据低压油泵工作使能,控制低压油泵电机工作;低压油泵控制器反馈低压油泵的工作状态;车辆正常运行时,整车控制器判断车辆是否满足高压油泵恢复工作条件;车辆满足高压油泵恢复工作条件,高压油泵控制器根据高压油泵恢复使能,控制高压油泵电机恢复工作。本发明的低压油泵可以在高压油泵出现故障时持续保持正常工作状态,且在高压油泵系统故障恢复后,控制停止低压油泵工作,切换至高压油泵系统继续工作,保障了车辆转向系统的正常工作。
