The invention discloses an operation method of an automobile body controller integrated with an intelligent electricity supplementing function, and belongs to the technical field of automobile body electronics, a novel storage battery voltage monitoring mode is provided, the automobile body controller obtains the real-time voltage value of an automobile storage battery from a sampling circuit every 4 hours, and if the monitored voltage value is smaller than 12 V, the automobile storage battery is powered on; if yes, a power supply request is sent through a CAN bus, the VCU judges the high-voltage condition of the whole vehicle after receiving the request, if the high-voltage condition of the whole vehicle passes, the BMS continuously charges the storage battery for 30 min through the DCDC, and in the charging process, the vehicle door is opened, the voltage of the BMS single battery is lower than 3.25 V or the VCU does not respond to the power supply request for 5 s, and if one of the conditions is met, power supply is quitted. And the manufacturing cost of the automobile is reduced on the premise of ensuring functions.
本发明公开了一种集成智能补电功能车身控制器的运行方法,属于汽车车身电子技术领域,本发明提供一种新型的蓄电池电压监测方式,车身控制器每4h从采样电路获取汽车蓄电池的实时电压值,若监测电压值小于12V,则通过CAN总线发送补电请求,VCU收到请求后判断整车高压情况,若通过,则BMS通过DCDC对蓄电池进行持续30min的充电,且充电过程中,车门打开、BMS单体电池电压低于3.25V或VCU持续5s未响应补电请求,满足其中之一,则退出补电,综上所述,车身控制器集成智能补电功能,在保证功能的前提下降低了汽车制造成本。
