The invention provides a double-source oil pump motor control method and system, an automobile and a storage medium. The double-source oil pump motor control method comprises the steps that when a starting instruction is obtained, a vehicle control unit enables a low-pressure oil pump controller, and the low-pressure oil pump controller drives a double-source oil pump motor to work through a preset position sensor vector control method; and when the rotating speed of the double-source oil pump motor reaches the preset rotating speed, the whole vehicle controller enables the high-pressure oil pump controller and sends a work stopping instruction to the low-pressure oil pump controller, and the high-pressure oil pump controller drives the double-source oil pump motor to work by adopting a preset non-sensing position observation algorithm. According to the double-source oil pump motor control method, the low-pressure oil pump controller can be adopted to start the motor, the defect that the position of a motor rotor is inaccurately estimated in the low-speed stage through a high-pressure oil pump controller non-sensing control method is overcome, the oil pump motor control precision and the anti-interference capacity are improved, and starting failure is avoided.
本发明提供一种双源油泵电机控制方法、系统、汽车、存储介质,该双源油泵电机控制方法包括:当获取到启动指令时,整车控制器使能低压油泵控制器,低压油泵控制器采用预设位置传感器矢量控制法驱动双源油泵电机工作;当双源油泵电机的转速达到预设转速时,整车控制器使能高压油泵控制器并向低压油泵控制器发送停止工作指令,高压油泵控制器采用预设无传感位置观测算法驱动双源油泵电机工作。应用本发明双源油泵电机控制方法可以采用低压油泵控制器启动电机,弥补了高压油泵控制器无传感控制法在低速阶段电机转子位置估计不准的不足,提高了油泵电机控制精度和抗干扰能力,避免启动失败。
