Once a leakage occurs, it is likely to cause damage to the human body, even life-threatening. In addition, even if the voltage is not high when the leakage is discharged, it will also affect other electronic equipment on the car and cause control failure. There are traffic hazards. Therefore, automobile leakage detection is very necessary.
然而，目前汽车配电***日益复杂，每个品牌车辆电气架构不同，选用的保险丝型号和布置也各不相同，现有对于车辆漏电的检测方案并不通用。另外，一旦车辆发生漏电，由于车辆线路分支数目多、电器部件数量复杂，维修技师在进行检测的过程中，常常需要人工翻阅汽车说明书或者人工翻阅维修资料进行对照检测，这样的检测方式将增加检测时间以及人工成本。However, the current automotive power distribution system is becoming more and more complex. The electrical structure of each brand of vehicle is different, and the type and layout of the selected fuses are also different. The existing detection schemes for vehicle leakage are not universal. In addition, once the vehicle leaks electricity, due to the large number of vehicle circuit branches and the complex number of electrical components, maintenance technicians often need to manually review the car manual or manually review the maintenance data for comparison and inspection during the inspection process. time and labor costs.

目前，对于出现可能的车辆漏电故障，维修工程师需要确定车辆是否存在真实漏电，然后确定大的分支线路是否漏电，最终确定小的分支线路或电器是否漏电。然而，在这种检测过程中，维修工程师需要一边检测一边查阅汽车说明书进行检测，可见，该检测方式复杂、耗费时间长，增加人工成本，漏电检测较为困难且不精准。At present, for possible vehicle leakage faults, maintenance engineers need to determine whether there is real leakage in the vehicle, then determine whether large branch lines are leaking, and finally determine whether small branch lines or electrical appliances are leaking.

Please refer to FIG. 1. FIG. The circuit system includes a battery 20, a first switch Q1, a second switch Q2, a first fuse F1, a second fuse F2, a third fuse F3, a fourth fuse F4, a first electric device 31, a second electric device 32 and The third electrical equipment 33 .

For automobiles of different brands and different vehicle models, the number of fuse boxes and the position of the fuse boxes in the vehicle are also different.
请参阅图2，本发明实施例提供一种车辆漏电检测方法，所述方法包括：Please refer to FIG. 2 , an embodiment of the present invention provides a vehicle leakage detection method, the method comprising:
步骤S1：在所述车辆处于休眠状态的情况下，获取所述车辆的电池负极总电流；Step S1: when the vehicle is in a dormant state, obtain the total negative battery current of the vehicle;
当车辆进入休眠状态时，车辆上只有少量的电控***会以等待的状态进行工作，例如车身防盗***、智能钥匙开启***会一直等待、搜寻钥匙或用户发出的信号，但因为是工作在休眠状态，所以耗电量极低(一般在20mA左右)，其他***，例如发动机控制、变速箱控制、安全气囊、ABS***等则可进入完全不工作的深度休眠状态，几乎不耗费蓄电池的电量。因此，为了能精确地检测出车辆是否处于漏电状态，则首先应该让车辆处于休眠状态，即处于低功耗状态。然后，获取流经蓄电池负极的总电流值为所述电池负极总电流。When the vehicle enters the dormant state, only a small number of electronic control systems on the vehicle will work in a waiting state, such as the body anti-theft system, the smart key opening system will always wait, search for the key or the signal sent by the user, but because they are working in dormancy state, so the power consumption is extremely low (generally around 20mA), and other systems, such as engine control, gearbox control, airbag, ABS system, etc., can enter a deep sleep state that does not work at all, and consumes almost no battery power. Therefore, in order to accurately detect whether the vehicle is in a leakage state, the vehicle should first be in a dormant state, that is, in a low power consumption state. Then, the value of the total current flowing through the negative pole of the battery is obtained as the total current of the negative pole of the battery.
具体的，当判断出车辆处于休眠状态时，可以通过终端提示用户对电池负极总电流进行测量，其中，测量方式可以为电流钳免拆测量法、万用表电流档串联测量法或者是现有技术的其他一切合适的测量方式；然后，提示用户通过终端输入测量得到的电池负极总电流，从而可以获取所述车辆的电池负极总电流。应当注意的是，在进行测量电池负极总电流时，电流测量点越靠近蓄电池负极越准确。实际应用中，判断车辆处于休眠状态的方法可以采用现有技术中一切合适的判断方法，终端可以为手机、电脑、触摸屏或者是其他一切合适的可用于交互的设备，在此不做限定。Specifically, when it is determined that the vehicle is in a dormant state, the terminal can prompt the user to measure the total current of the negative electrode of the battery. All other suitable measurement methods; then, the user is prompted to input the measured total negative battery current through the terminal, so that the total negative battery current of the vehicle can be obtained. It should be noted that when measuring the total current of the negative pole of the battery, the closer the current measurement point is to the negative pole of the battery, the more accurate it is. In practical application, the method for judging that the vehicle is in a dormant state can adopt any suitable judging method in the prior art, and the terminal can be a mobile phone, a computer, a touch screen or any other suitable device that can be used for interaction, which is not limited here.
步骤S2：根据所述电池负极总电流，确定车辆状态，所述车辆状态包括漏电状态和未漏电状态；Step S2: Determine the vehicle state according to the total negative electrode current of the battery, and the vehicle state includes a leakage state and a non-leakage state;
前述提到，当车辆工作在休眠状态时，蓄电池的耗电量极低，因此，根据步骤S1获取的电池负极总电流可以判断出车辆是否处于漏电状态。As mentioned above, when the vehicle is in the dormant state, the power consumption of the battery is extremely low. Therefore, according to the total current of the negative electrode of the battery obtained in step S1, it can be determined whether the vehicle is in a leakage state.
在其中一些实施例中，在执行步骤S1之前，请参阅图3，所述方法还包括：In some of these embodiments, before performing step S1, referring to FIG. 3, the method further includes:
步骤S11：获取所述车辆的车辆型号。Step S11: Obtain the vehicle model of the vehicle.
由于品牌不同、车型不同，在维修资料上、用于判断车辆是否休眠或者是否漏电的休眠电流参考值不同的，为了准确判断车辆是否处于休眠状态或者车辆是否漏电，应该首先获取所述车辆的车辆型号。Due to different brands and models, the reference value of dormancy current used to judge whether the vehicle is dormant or leakage is different in the maintenance information. In order to accurately determine whether the vehicle is dormant or whether the vehicle is leakage, you should first obtain the vehicle model.
具体的，在其中一些实施例中，可以通过OBD设备获取所述车辆型号。或者，在其他一些实施例中，可以通过获取所述车辆的车辆识别(Vehicle Identification Number,VIN)码，根据所述VIN码得到所述车辆型号。其中，VIN码又称为车架号码，是一组由十七个字母或数字组成，用于汽车上的一组独一无二的号码，可以识别汽车的生产商、引擎、底盘序号及其他性能等资料，据此来获取车辆型号。Specifically, in some of these embodiments, the vehicle model can be acquired through an OBD device. Or, in some other embodiments, the vehicle model can be obtained according to the VIN code by acquiring the vehicle identification number (Vehicle Identification Number, VIN) code of the vehicle. Among them, the VIN code, also known as the frame number, is a group of 17 letters or numbers, a unique number used on a car, which can identify the manufacturer, engine, chassis number and other performance information of the car. , based on which the vehicle model is obtained.
进一步地，在其中一些实施例中，请参阅图4，所述步骤S2包括：Further, in some embodiments, please refer to FIG. 4, the step S2 includes:
步骤S21：根据所述车辆型号、以及车辆型号与休眠电流参考值的对应关系，得到所述车辆的休眠电流参考值；Step S21: Obtain the dormant current reference value of the vehicle according to the vehicle model and the corresponding relationship between the vehicle model and the dormant current reference value;
步骤S22：若所述电池负极总电流大于所述休眠电流参考值，则所述车辆处于漏电状态；Step S22: If the total negative current of the battery is greater than the dormant current reference value, the vehicle is in a leakage state;
步骤S23：若所述电池负极总电流小于或等于所述休眠电流参考值，则所述车辆处于未漏电状态。Step S23: If the total negative electrode current of the battery is less than or equal to the dormant current reference value, the vehicle is in a state of no electricity leakage.
具体的，预先可以构建一个休眠电流参考值数据库，所述休眠电流参考值数据库存有车辆型号与休眠电流标准值之间的一一对应关系、和/或，所述休眠电流参考值数据库存有车辆型号与休眠电流警示值之间的一一对应关系。通常，同一品牌下的不同车型之间休眠电流标准值一致、同一品牌下的不同车型之间休眠电流警示值也一致，因此，可在休眠电流参考值数据库中、建立不同 品牌车型与休眠电流警示值、标准值的对应关系表，例如表1。实际应用中，该休眠电流参考值数据库可以灵活设置，在此不做限定。Specifically, a dormant current reference value database can be constructed in advance, the dormant current reference value database has a one-to-one correspondence between the vehicle model and the dormant current standard value, and/or, the dormant current reference value database has a One-to-one correspondence between vehicle models and dormant current warning values. Usually, the sleep current standard value is consistent between different models under the same brand, and the sleep current warning value is also consistent among different models under the same brand. Therefore, different brands of models and sleep current warning values can be established in the sleep current reference value database. Correspondence table of values and standard values, such as Table 1. In practical applications, the dormant current reference value database can be flexibly set, which is not limited here.
表1不同品牌车型与休眠电流警示值、标准值的对应关系表Table 1 Corresponding relationship between different brands of models and dormant current warning value and standard value
NO.No. 品牌brand 休眠电流警示值Sleep current warning value 休眠电流标准值Sleep current standard value
11 奔驰mercedes benz 50mA50mA ×x
22 宝马 BMW 80mA80mA 21mA21mA
33 大众奥迪Volkswagen Audi 50mA50mA 30mA30mA
44 福特ford 50mA50mA 25-50mA25-50mA

99 标志，雪铁龙logo, citroen ×x 12-25mA12-25mA
1010 比亚迪BYD 70mA70mA ×x
在表1中，×值代表空值，后续可以进行采集补充。那么，通过获取上述表1的对应关系，然后，根据该对应关系可建立车辆休眠电流数据库。接着，可以在该休眠电流参考值数据库中确定休眠电流参考值，用于后续判断车辆是否处于漏电状态。为了提高检测的准确度，应当优选车辆休眠电流标准值作为休眠电流参考值，如果实际中无标准值，则可以选择休眠电流警示值作为休眠 电流参考值。例如，在表1中的奔驰品牌下则无休眠电流标准值，因此，对于奔驰品牌的车辆，可以选择奔驰品牌的休眠电流警示值50mA作为奔驰品牌的休眠电流参考值。那么，对于奔驰品牌的车辆，如果获取的电池负极总电流大于休眠电流参考值50mA，则该车辆处于漏电状态，如果获取的电池负极总电流小于或等于休眠电流参考值50mA，则该车辆处于未漏电状态。In Table 1, the × value represents a null value, which can be collected and supplemented later. Then, by obtaining the corresponding relationship in the above table 1, then, the vehicle sleep current database can be established according to the corresponding relationship. Next, the dormant current reference value may be determined in the dormant current reference value database, which is used for subsequently determining whether the vehicle is in a leakage state. In order to improve the detection accuracy, the standard value of the vehicle sleep current should be selected as the reference value of the sleep current. If there is no standard value in practice, the warning value of the sleep current can be selected as the reference value of the sleep current. For example, there is no dormant current standard value under the Mercedes-Benz brand in Table 1. Therefore, for Mercedes-Benz brand vehicles, the dormant current warning value of the Mercedes-Benz brand of 50mA can be selected as the dormant current reference value of the Mercedes-Benz brand. Then, for a Mercedes-Benz brand vehicle, if the total negative current of the battery obtained is greater than the reference value of the dormant current of 50mA, the vehicle is in a leakage state; Leakage state.
实际应用中，数据库的构建和休眠电流参考值的选定可根据实际需要进行设置，在此不需拘泥于本实施例中的限定。In practical applications, the construction of the database and the selection of the dormant current reference value can be set according to actual needs, and there is no need to be constrained by the limitations in this embodiment.
步骤S3：若所述车辆状态为漏电状态，则获取各支路的支路电流；Step S3: If the state of the vehicle is a leakage state, obtain the branch current of each branch;
前述提到，在车辆电路***中，每一支路上对应串接有每一保险丝，那么，可以通过获取流经保险丝的电路作为该保险丝对应的支路电流。As mentioned above, in the vehicle electrical system, each branch is correspondingly connected in series with each fuse, then, the circuit flowing through the fuse can be obtained as the branch current corresponding to the fuse.
具体的，在其中一些实施例中，请参阅图5，所述步骤S3包括：Specifically, in some of these embodiments, please refer to FIG. 5, the step S3 includes:
步骤S31：根据所述车辆型号，得到所述车辆的各保险丝的保险丝编号，所述各保险丝分别串联连接于所述各支路中；Step S31: According to the vehicle model, obtain the fuse numbers of the fuses of the vehicle, and the fuses are respectively connected in series in the branches;

请参阅图6，图6为本发明实施例适用的一种保险丝盒的示意图，如图6所示，在该保险丝盒上集成有汽车电路***中的保险丝，并且每一保险丝都具有唯一的数字编号1、2、3、……、N。因此，可以预先构建不同车辆型号的保险丝数据库，所述保险丝数据库中存有车辆型号与保险丝编号的对应关系表。然后，通过终端提示用户按照保险丝编号逐一对保险丝两端的电压进行检测，其中，用户可以使用现有技术中的万用表mv档逐一测量保险丝两端的电 压，并通过终端输入每一保险丝两端的保险丝电压，从而可以获取每一保险丝的保险丝电压。接着，根据保险丝编号和保险丝电压，得到流经每一保险丝的保险丝电流，最后，根据所述保险丝电流，得到每一保险丝电流对应的支路电流。Please refer to Fig. 6, Fig. 6 is the schematic diagram of a kind of fuse box applicable to the embodiment of the present invention, as shown in Fig. 6, the fuse in the automobile circuit system is integrated on the fuse box, and each fuse has a unique number Number 1, 2, 3, ..., N. Therefore, fuse databases of different vehicle models can be constructed in advance, and the fuse database stores a correspondence table between vehicle models and fuse numbers. Then, the terminal prompts the user to detect the voltage at both ends of the fuse one by one according to the fuse number, wherein the user can use the multimeter mv file in the prior art to measure the voltage at both ends of the fuse one by one, and input the fuse voltage at both ends of each fuse through the terminal, Thus, the fuse voltage of each fuse can be obtained. Next, the fuse current flowing through each fuse is obtained according to the fuse number and the fuse voltage, and finally, according to the fuse current, the branch current corresponding to each fuse current is obtained.
由于不同编号下的保险丝对应的保险丝型号不同，在其中一些实施例中，请参阅图7，所述步骤S33还包括：Since the fuse models under different numbers correspond to different fuse models, in some embodiments, please refer to FIG. 7, the step S33 also includes:

步骤S332：根据所述保险丝型号和所述保险丝电压，得到所述保险丝电流。Step S332: Obtain the fuse current according to the fuse model and the fuse voltage.
具体地，在构建保险丝数据库时，还可以将不同车辆型号下、保险丝编号与保险丝型号的对应关系表存储至保险丝数据库中。然后，再预先构建保险丝电压降表数据库，所述保险丝电压降表数据库存有保险丝型号、保险丝两端电压差与流经保险丝的保险丝电流的一一对应关系表，如下表2。Specifically, when constructing the fuse database, the correspondence table of fuse numbers and fuse models under different vehicle models may also be stored in the fuse database. Then, the fuse voltage drop table database is pre-built, and the fuse voltage drop table database has a one-to-one correspondence table of the fuse model, the voltage difference across the fuse and the fuse current flowing through the fuse, as shown in Table 2 below.

Figure PCTCN2022103704-appb-000001
接着，依据车辆型号、保险丝编号和保险丝数据库，得到不同编号保险丝的保险丝型号；再然后，通过每一保险丝的保险丝电压、保险丝型号和保险丝电压降表数据库，得到流经保险丝的保险丝电流。其中，保险丝型号也可以用颜色来表示，对于标准的保险丝，其颜色也可以代表保险丝型号，如表2中型号为Mini2Amp的保险丝可以用灰色来表示。Then, according to the vehicle model, the fuse number and the fuse database, the fuse models of the fuses with different numbers are obtained; and then, the fuse current flowing through the fuse is obtained through the fuse voltage of each fuse, the fuse model and the fuse voltage drop table database.

可以理解的是，当车辆处于漏电时，支路电流越接近电池负极总电流的支路处于故障状态，因此，可以依据支路电流和电池负极总电流的大小关系来判断支路状态。It can be understood that when the vehicle is leaking, the branch whose current is closer to the total negative battery current is in a fault state. Therefore, the state of the branch can be judged based on the relationship between the branch current and the total negative battery current.
具体的，可将各所述保险丝电流和电池负极总电流逐一作差并取绝对值，并从中得到最大绝对值，那么，该最大绝对值对应的保险丝所在支路则为故障状态，其余支路为正常状态，或者，在得到绝对值后，预设一个绝对值阈值，若绝对值小于或等于该绝对值阈值，则该绝对值对应的保险丝所在支路为故障状态，若绝对值大于该绝对值阈值，则该绝对值对应的保险丝所在支路为正常状态。实际应用中，还可以用作商法判断支路状态，在此不需拘泥于本实施例中的限定。Specifically, the current of each fuse and the total current of the negative pole of the battery can be compared one by one and the absolute value can be taken, and the maximum absolute value can be obtained therefrom. Then, the branch where the fuse corresponding to the maximum absolute value is located is in a fault state, and the other branches It is in a normal state, or, after obtaining the absolute value, preset an absolute value threshold, if the absolute value is less than or equal to the absolute value threshold, the branch where the fuse corresponding to the absolute value is located is in a fault state, if the absolute value is greater than the absolute value value threshold, the branch corresponding to the absolute value of the fuse is in a normal state. In practical applications, it can also be used as a commercial method to judge the state of the branch, and there is no need to be constrained by the limitation in this embodiment.
