The invention discloses a DCDC converter control method and device and a whole vehicle control unit, and relates to the technical field of automobiles, and the disclosed DCDC converter control method comprises the steps that current operation information of a whole vehicle is obtained; adjusting the logic state of the enabling flag bit according to the current operation information; the operating state of the DCDC converter is controlled by allowing the logic state of the enable flag bit. The logic state of the enabling flag bit is adjusted through the current operation information of the whole vehicle, so that compared with the prior art, the operation state of the DCDC converter can be controlled by the current operation information, the correlation between the operation state of the DCDC converter and the current operation information is realized, the control precision of the DCDC converter is improved, and the user experience is improved. And the influence on the normal operation of the vehicle caused by unreasonable control of the DCDC converter is avoided.
本申请公开了一种DCDC转换器控制方法、装置及整车控制单元,涉及汽车技术领域,公开的DCDC转换器控制方法包括:获取整车的当前运行信息;根据当前运行信息对允许使能标志位的逻辑状态进行调整;通过允许使能标志位的逻辑状态控制DCDC转换器的运行状态。由于本申请通过整车的当前运行信息对允许使能标志位的逻辑状态进行调整,因此,相较于现有技术,本申请能够使DCDC转换器的运行状态受当前运行信息的控制,实现了DCDC的运行状态与当前运行信息之间的关联,提高了DCDC转换器的控制精度,避免了DCDC转换器控制不合理而导致对车辆的正常运行产生影响。
