The invention relates to the technical field of vehicles, and discloses a vehicle wake-up control method and device, a vehicle and a storage medium. The method comprises the steps that if it is detected that the current first power supply voltage of the electric control unit is smaller than a preset power supply threshold value, a first wake-up source is configured, and the electric control unit is controlled to enter a dormant state; when the wake-up event occurs, if a second wake-up source corresponding to the wake-up event is a target wake-up source, initializing ADC peripherals and controlling the electric control unit to feed a dog, and if the current second power supply voltage of the electric control unit is greater than or equal to a preset power supply threshold value, initializing all peripherals and controlling the electric control unit to enter a normal working state, and the electric control unit periodically feeds the dog and detects the current third power supply voltage in real time. In the power supply voltage change process, the electronic control unit is controlled to sleep intermittently and execute corresponding logic according to the current power supply state after being awakened periodically, so that the power consumption is reduced, and meanwhile, the stability of normal work of the electronic control unit can be ensured.

    本申请涉及车辆技术领域,公开了一种车辆唤醒控制方法、装置、车辆和存储介质。该方法包括:若检测到电控单元当前的第一供电电压小于预设供电阈值,则配置第一唤醒源,并控制电控单元进入休眠状态;在唤醒事件发生时,若唤醒事件对应的第二唤醒源为目标唤醒源,初始化ADC外设并控制电控单元喂狗,若电控单元当前的第二供电电压大于等于预设供电阈值,则初始化所有外设,并控制电控单元进入正常工作状态,以使得电控单元周期性喂狗以及实时检测当前的第三供电电压。本申请在供电电压变化过程中,控制电控单元间歇休眠,并周期唤醒后根据当前供电状态来执行相应逻辑,进而在降低功耗的同时还能保证电控单元正常工作的稳定性。
