The invention discloses an oil pump motor locked-rotor fault clearing method, device and equipment and a storage medium, and relates to the technical field of automobiles. According to the method, when it is detected that an oil pump motor generates a locked-rotor fault, power output of a whole vehicle is limited, and the whole vehicle is controlled to enter a limp mode with low heat production after waiting for limp buffer time; then the real-time working current of the oil pump motor is increased to the maximum, the real-time rotating speed of the oil pump motor is tried to be increased, and if the real-time rotating speed still cannot reach the preset rotating speed within the first preset time, the oil pump motor is controlled to rotate reversely so as to try to increase the real-time rotating speed of the oil pump motor again; and if the real-time rotating speed reaches the preset rotating speed within the second preset time, the locked-rotor fault of the oil pump motor is automatically eliminated, and the power output of the whole vehicle is not limited any more. By means of the method, self-recovery can be conducted quickly after the locked-rotor fault occurs to the oil pump motor of the whole vehicle, the situation that the whole vehicle cannot run normally for a long time due to the locked-rotor fault is reduced, and the user experience feeling is improved.
本申请公开了一种油泵电机堵转故障清除方法、装置、设备及存储介质,涉及汽车技术领域,该方法在检测到油泵电机发生堵转故障时,限制整车的功率输出,并在等待跛行缓冲时间后控制整车进入产热量低的跛行模式,再将油泵电机的实时工作电流提升至最大,尝试提升油泵电机的实时转速,若在第一预设时间内实时转速依旧无法达到预设转速,则控制油泵电机反向旋转以重新尝试提升油泵电机的实时转速,若在第二预设时间内实时转速达到了预设转速,则自动清除油泵电机的堵转故障,不再限制整车的功率输出。通过上述方法可以在整车的油泵电机发生堵转故障后,快速进行自恢复,减少因堵转故障造成整车长时间无法正常行驶,提升用户体验感。
