The embodiment of the invention provides an automobile direct-current converter control method and device and a vehicle, relates to the technical field of automobile electronics and electricities, and mainly comprises the steps of intermittently detecting a current enable signal state according to a preset period, obtaining a power demand of a whole vehicle load and the electric quantity of a storage battery, responding to the current enable signal state, and controlling the direct-current converter of the vehicle. After determining the detection sequence of the electricity demand and the electric quantity and the corresponding judgment strategy, executing the detection judgment strategy and deciding whether to adjust the enable signal; and finally, outputting a target enable signal to the direct current converter according to the decision result, wherein the target enable signal can comprise a first enable signal for triggering the direct current converter to enter a preset activation mode and a second enable signal for triggering the direct current converter to enter a preset standby mode. According to real-time feedback, the working state of the direct-current converter is flexibly regulated and controlled, so that an electrical system of the whole vehicle has higher adaptability, and power requirements under different working conditions can be effectively met.

    本申请实施例提出了一种汽车直流变换器控制方法、装置及车辆,涉及汽车电子电气技术领域,主要是按预设周期间歇性检测当前的使能信号状态,并获取整车负载的用电需求与蓄电池的电量,响应于当前的使能信号状态,确定用电需求与电量的检测次序及对应的判断策略之后,执行检测判断策略并决策是否调整使能信号;最后根据决策结果向直流变换器输出目标使能信号,目标使能信号可以包括触发直流变换器进入预设的激活模式的第一使能信号,以及触发直流变换器进入预设的待机模式的第二使能信号。本申请根据实时反馈,灵活调控直流变换器的工作状态,使整车电气系统更具适应性,能够有效应对不同工况下的电力需求。
