The invention discloses a method and system for identifying abnormal electric appliances of an automobile, and the method comprises the steps: enabling a whole automobile to enter a dormant state after the whole automobile is locked, and detecting the state of a storage battery; judging whether the current of the storage battery is greater than a preset quiescent current or not, if so, numbering each electric appliance in sequence, obtaining a corresponding theoretical current value Ix according to different combination modes of abnormal power utilization of the electric appliances, and calculating a minimum value f (x) min in absolute values of difference values between each theoretical current value Ix and an actual current value; wherein x in the theoretical current value Ix is the accumulated value of the serial numbers of the electric appliances with the abnormal electricity utilization condition; obtaining a theoretical current value corresponding to f (x) min; the x value is converted into a binary number, each bit of the binary number reflects the working state of the electric appliance, and the abnormal electric appliance is acquired according to the binary number; the method has the advantage that the electric appliance which works abnormally after the vehicle is locked can be accurately positioned.
本发明公开了一种汽车异常用电器的识别方法及系统,方法包括:整车闭锁后进入休眠状态,检测蓄电池状态;判断蓄电池电流是否大于预设的静态电流,若是则每个用电器按顺序编号,根据用电器异常用电的不同组合方式获得对应的理论电流值Ix,计算每个理论电流值Ix与实际电流值差值的绝对值中的最小值f(x)min;其中,理论电流值Ix中x是存在异常用电情况的用电器的编号的累加值;获得f(x)min对应的理论电流值;将x值转换为的二进制数,二进制数的每一位反映用电器的工作状态,根据二进制数获取异常的用电器;本发明的优点在于:能够准确定位锁车后异常工作的用电器。
