The invention discloses a vehicle low-voltage power supply voltage monitoring method and system, a storage medium and a vehicle, and the method comprises the following steps that a vehicle controller carries out the self-inspection after the power-on awakening, controls the DC/DC power-on when there is no fault in the self-inspection, and transmits an awakening message to the DC/DC for awakening the DC/DC; the whole vehicle controller receives a self state message fed back after the DC/DC is awakened, executes a whole vehicle power-on time sequence when determining that the DC/DC has no fault according to the self state message, and controls the DC/DC to work after the whole vehicle is successfully powered on; and the whole vehicle controller monitors the power supply voltage of the whole vehicle controller to judge whether the low-voltage power supply voltage of the vehicle fails or not, if yes, the whole vehicle power-off time sequence is executed, and the vehicle instrument is controlled to send out failure prompt information. Therefore, the vehicle low-voltage power supply voltage monitoring method can accurately and effectively monitor the low-voltage power supply voltage of the vehicle, discover the fault of the vehicle low-voltage power supply voltage in time, avoid the phenomenon that the vehicle cannot be powered on and started, and improve the user experience.

    本发明公开了一种车辆低压供电电压监测方法与系统、存储介质、车辆,其中,监测方法包括以下步骤:整车控制器在上电唤醒后进行自检,并在自检无故障时控制DC/DC上电,以及发送唤醒报文给DC/DC以唤醒DC/DC;整车控制器接收DC/DC被唤醒后反馈的自身状态报文,并根据该自身状态报文确定DC/DC无故障时执行整车上电时序,并在整车上电成功后控制DC/DC进行工作;整车控制器对自身供电电压进行监测以判断车辆低压供电电压是否出现故障,如果出现故障,则执行整车下电时序,并控制车辆仪表发出故障提示信息。由此,该车辆低压供电电压监测方法能够准确有效地监测车辆的低压供电电压,及时发现车辆低压供电电压存在的故障,避免车辆无法上电启动的现象发生,提高用户体验。
