[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0031] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0032] The embodiments of the present application provide a terminal calibration method, device, equipment, medium and vehicle, which can automatically obtain the target wire diameter, target terminal, loop current and preset temperature of the target loop, and then determine the target rated current of the target terminal at the preset temperature according to the preset correspondence between the temperature corresponding to the target terminal under the target wire diameter and the rated current, and then obtain the calibration result of the target terminal by checking whether the target rated current is less than the loop current. Therefore, the embodiments of the present application provide a standardized method for calibrating the current carrying capacity of the terminal itself.

[0033] A terminal calibration method provided in an embodiment of the present application is introduced in detail below.

[0034] Figure 1A schematic flow chart of a terminal calibration method provided by an embodiment of the present application is shown, and the execution subject of the terminal calibration method may be a terminal calibration device. It should be noted that the above execution subject does not constitute a limitation to the present application.

[0035] like Figure 1 As shown, the terminal calibration method may include the following steps:

[0036] S110, obtaining loop information, loop current, and preset temperature of the target loop;

[0037] S120, determining a target rated current of the target terminal at a preset temperature according to a preset corresponding relationship between temperature and rated current;

[0038] S130, checking whether the target rated current is less than the loop current, and obtaining the checking result of the target terminal.

[0039] Thus, the target wire diameter, target terminal, loop current and preset temperature of the target loop can be automatically obtained, and then the target rated current of the target terminal at the preset temperature can be determined according to the preset correspondence between the temperature corresponding to the target terminal at the target wire diameter and the rated current, and then the verification result of the target terminal can be obtained by verifying whether the target rated current is less than the loop current. Therefore, the embodiment of the present application provides a standardized method for verifying the current carrying capacity of the terminal itself.

[0040] In S110, the loop information may include a target wire diameter and a target terminal. The target wire diameter may be the diameter of the wire included in the target loop. The target terminal may be a terminal connected to both ends of the target loop, or a terminal connected to one end of the target loop. The preset temperature may be the temperature of the environment in which the target loop is located, and may be manually set based on the actual environment and experience.

[0041] Here, the loop current of the target loop needs to be determined according to the connection status of both ends of the target loop. The connection status may refer to the connection objects at both ends of the target loop. For example, the connection objects at both ends of the target loop may include one or two of electrical appliances, welding points, fuse boxes, grounding, and line-to-line connectors (INLINE). Different ways of determining the loop current are different for different connection states.

[0042] The following describes how to determine the loop current for various possible connection states at both ends of the target loop.

[0043] In some implementations, in order to more accurately determine the loop current of the target loop, obtaining the loop current may include:

[0044] Get the connection status of both ends of the target loop;

[0045] When the connection state represents that one end of the target circuit is connected to the first electrical appliance and the other end is connected to the second electrical appliance, obtaining the rated current of the first electrical appliance and the rated current of the second electrical appliance;

[0046] Comparing the rated current of the first electrical appliance with the rated current of the second electrical appliance to obtain a smaller target rated current;

[0047] Determine the target rated current as the loop current.

[0048] Here, the connection status of the two ends of the target loop can be obtained first. If the connection status indicates that one end of the target loop is connected to the first electrical appliance and the other end is connected to the second electrical appliance, the rated current of the first electrical appliance and the rated current of the second electrical appliance can be obtained, and then the rated current of the first electrical appliance and the rated current of the second electrical appliance are compared to determine that the smaller of the two rated currents is the target rated current, and the target rated current is determined as the loop current of the target loop.

[0049] That is to say, if electrical appliances are connected at both ends of the target loop, the loop current is equal to the rated current of the electrical appliance at the end with the smaller rated current among the electrical appliances connected at both ends of the target loop.

[0050] In this way, through the above process, when electrical appliances are connected to both ends of the target circuit, the loop current of the target circuit can be determined more accurately.

[0051] In some implementations, in order to more accurately determine the loop current of the target loop, after obtaining the connection status of both ends of the target loop, the method may further include:

[0052] When the connection state represents that one end of the target circuit is connected to an electrical appliance and the other end is connected to a welding point, a main circuit of the welding point is obtained;

[0053] Determine whether the main circuit of the solder joint is the target circuit;

[0054] When the main circuit of the welding point is the target circuit, obtaining the rated current of the electrical appliance in at least one first circuit connected to the welding point except the target circuit;

[0055] Calculating the sum of rated currents of electrical appliances in at least one first circuit to obtain a circuit current;

[0056] When the main circuit of the welding point is not the target circuit, obtaining the rated current of the electrical appliance in at least one second circuit connected to the welding point;

[0057] The sum of the rated currents of the electrical appliances in at least one second circuit is calculated to obtain the circuit current.

[0058] Among them, the main circuit of the welding point can be preset.

[0059] Here, after obtaining the connection status of both ends of the target circuit, if the connection status indicates that one end of the target circuit is connected to an electrical appliance and the other end is connected to a welding point, the main circuit of the welding point can be obtained to determine whether the main circuit of the welding point is the target circuit.

[0060] If the main circuit of the welding point is the target circuit, the rated current of the electrical appliances in at least one first circuit other than the target circuit among all the circuits connected to the welding point can be obtained, and then the sum of the rated currents of the electrical appliances in the at least one first circuit can be calculated to obtain the circuit current of the target circuit.

[0061] If the main circuit of the welding point is not the target circuit, the rated current of the electrical appliances in all circuits connected to the welding point (that is, at least one second circuit) can be obtained, and then the sum of the rated currents of the electrical appliances in the at least one second circuit can be calculated to obtain the circuit current of the target circuit.

[0062] That is, if one end of the target circuit is connected to an electrical appliance and the other end is connected to a welding point, it is necessary to determine whether the target circuit is the main circuit of the welding point. If the target circuit is the main circuit of the welding point, the loop current of the target circuit is equal to the sum of the rated currents of the electrical appliances in all circuits connected to the welding point, except the target circuit. If the target circuit is not the main circuit of the welding point, the loop current of the target circuit is equal to the sum of the rated currents of the electrical appliances in all circuits connected to the welding point.

[0063] In this way, through the above process, the loop current of the target loop can be determined more accurately when one end of the target loop is connected to the electrical appliance and the other end is connected to the welding point.

[0064] In some implementations, in order to more accurately determine the loop current of the target loop, after obtaining the connection status of both ends of the target loop, the method may further include:

[0065] When the connection state represents that one end of the target circuit is connected to the electrical appliance and the other end is connected to the first object, obtaining the rated current of the electrical appliance;

[0066] Determine the rated current of the electrical appliance as the loop current.

[0067] The first object may be an INLINE, a fuse box, or a ground.

[0068] Here, after obtaining the connection status at both ends of the target loop, if the connection status indicates that one end of the target loop is connected to an electrical appliance and the other end is connected to INLINE, a fuse box or ground, the rated current of the electrical appliance can be obtained and determined as the loop current of the target loop.

[0069] That is, if one end of the target circuit is connected to an appliance and the other end is connected to INLINE, a fuse box, or ground, the loop current of the target circuit is equal to the rated current of the appliance.

[0070] Thus, through the above process, the loop current of the target loop can be determined more accurately when one end of the target loop is connected to an electrical appliance and the other end is connected to an INLINE, a fuse box or ground.

[0071] In some implementations, in order to more accurately determine the loop current of the target loop, after obtaining the connection status of both ends of the target loop, the method may further include:

[0072] When the connection state represents that one end of the target circuit is connected to the second object and the other end is connected to the third object, obtaining the rated current of the electrical appliance connected to the third object;

[0073] Determine the rated current of the electrical appliance as the loop current.

[0074] The second object may be a fuse box or a ground, and the third object may be an INLINE or a soldering point.

[0075] Here, after obtaining the connection status of both ends of the target loop, if the connection status indicates that one end of the target loop is connected to a fuse box or ground and the other end is connected to INLINE, the rated current of the electrical appliance connected to INLINE can be obtained and the rated current of the electrical appliance can be determined as the loop current of the target loop.

[0076] If the connection state indicates that one end of the target circuit is connected to a fuse box or ground and the other end is connected to a welding point, the rated current of the electrical appliance connected to the welding point can be obtained, and the rated current of the electrical appliance can be determined as the loop current of the target circuit. It should be noted that if the welding point is connected to multiple electrical appliances, the sum of the rated currents of the multiple electrical appliances can be determined as the loop current of the target circuit.

[0077] That is, if one end of the target circuit is connected to the fuse box or ground and the other end is connected to INLINE, the loop current of the target circuit is equal to the rated current of the electrical appliance connected to INLINE.

[0078] If one end of the target loop is connected to the fuse box or ground and the other end is connected to the welding point, the loop current of the target loop is equal to the sum of the rated currents of at least one electrical appliance connected to the welding point.

[0079] Thus, through the above process, the loop current of the target loop can be determined more accurately when one end of the target loop is connected to the fuse box or ground and the other end is connected to the INLINE or welding point.

[0080] In some implementations, in order to more accurately determine the loop current of the target loop, after obtaining the connection status of both ends of the target loop, the method may further include:

[0081] When the connection state indicates that one end of the target loop is connected to the first INLINE and the other end is connected to the second INLINE, a current at the other end of the first INLINE is obtained, where the other end of the first INLINE is an end that is not connected to the target loop;

[0082] Determine whether the current at the other end of the first INLINE is 0;

[0083] When the current at the other end of the first INLINE is not zero, obtaining the rated current of the electrical appliance connected to the first INLINE;

[0084] When the current at the other end of the first INLINE is 0, the rated current of the electrical appliance connected to the second INLINE is obtained;

[0085] Determine the rated current of the electrical appliance as the loop current.

[0086] Here, after obtaining the connection status of both ends of the target loop, if the connection status indicates that one end of the target loop is connected to the first INLINE and the other end is connected to the second INLINE, the current at the other end of the first INLINE can be obtained to determine whether the current at the other end of the first INLINE is 0.

[0087] If the current at the other end of the first INLINE is not 0, it indicates that a useful appliance is connected to the other end of the first INLINE. Therefore, the rated current of the appliance connected to the first INLINE can be obtained and determined as the loop current of the target loop.

[0088] If the current at the other end of the first INLINE is 0, it indicates that the other end of the first INLINE is not connected to an electrical appliance, so the rated current of the electrical appliance connected to the second INLINE can be obtained and determined as the loop current of the target loop.

[0089] That is to say, if both ends of the target circuit are connected to INLINE, then for the INLINE connected to any one end (i.e., the first INLINE), it can be determined whether there is current at the end of the first INLINE that is not connected to the target circuit. If there is current, it can be indicated that the end of the first INLINE that is not connected to the target circuit is connected to an electrical appliance, in which case the loop current of the target circuit can be equal to the rated current of the electrical appliance; if there is current, it can be indicated that the end of the first INLINE that is not connected to the target circuit is not connected to an electrical appliance, in which case the loop current of the target circuit can be equal to the rated current of the electrical appliance connected to the second INLINE, which is the INLINE connected to the other end of the target circuit.

[0090] In this way, through the above process, the loop current of the target loop can be determined more accurately when both ends of the target loop are connected to INLINE.

[0091] In some implementations, in order to more accurately determine the loop current of the target loop, after obtaining the connection status of both ends of the target loop, the method may further include:

[0092] When the connection state represents that one end of the target circuit is connected to the solder joint and the other end is connected to INLINE, the main circuit of the solder joint is obtained;

[0093] Determine whether the main circuit of the solder joint is the target circuit;

[0094] When the main circuit of the welding point is the target circuit, obtaining the rated current of at least one electrical appliance connected to the welding point;

[0095] Calculate the sum of the rated currents of at least one electrical appliance to obtain the loop current;

[0096] When the main circuit of the welding point is not the target circuit, the rated current of at least one third electrical appliance connected to the welding point and the rated current of a fourth electrical appliance connected INLINE are obtained;

[0097] The sum of the rated current of the at least one third electrical consumer and the rated current of the fourth electrical consumer is calculated to obtain the loop current.

[0098] Here, after obtaining the connection status of both ends of the target loop, if the connection status indicates that one end of the target loop is connected to a welding point and the other end is connected to INLINE, the main loop of the welding point can be obtained to determine whether the main loop of the welding point is the target loop.

[0099] If the main circuit of the welding point is the target circuit, the rated currents of all electrical appliances (ie, at least one electrical appliance) connected to the welding point can be obtained, and then the sum of the rated currents of the at least one electrical appliance is calculated to obtain the circuit current of the target circuit.

[0100] If the main circuit of the welding point is not the target circuit, the rated current of all electrical appliances connected to the welding point (that is, at least one third electrical appliance) and the rated current of the fourth electrical appliance connected INLINE can be obtained, and then the sum of the rated current of the at least one third electrical appliance and the rated current of the fourth electrical appliance is calculated to obtain the circuit current of the target circuit.

[0101] That is, if one end of the target circuit is connected to the welding point and the other end is connected to the INLINE, it is necessary to determine whether the target circuit is the main circuit of the welding point. If the target circuit is the main circuit of the welding point, the loop current of the target circuit is equal to the sum of the rated currents of all electrical appliances connected to the welding point. If the target circuit is not the main circuit of the welding point, the loop current of the target circuit is equal to the sum of the rated currents of all electrical appliances connected to the welding point and the rated currents of the electrical appliances connected to the INLINE.

[0102] In this way, through the above process, the loop current of the target loop can be determined more accurately when one end of the target loop is connected to the welding point and the other end is connected to the INLINE.

[0103] In some examples, different determination processes of loop current in different connection states can be as follows: Figure 2 shown.

[0104] If the connection status at both ends of the target circuit indicates that both ends of the target circuit are connected to electrical appliances, S2100 is executed to determine whether the circuit current is equal to the smaller of the rated currents of the two electrical appliances.

[0105] If the connection status at both ends of the target circuit represents that one end of the target circuit is connected to an electrical appliance and the other end is connected to a welding point, execute S2211 to determine whether the target circuit is the main circuit of the welding point. If so, execute S2212, if not, execute S2213; S2212, determine that the loop current is equal to the welding point current, where the welding point current is equal to the sum of the rated currents of the electrical appliances in all circuits connected to the welding point, except the target circuit; S2213 determines that the loop current is equal to the sum of the welding point current and the electrical appliance current, that is, the sum of the rated currents of the electrical appliances in all circuits connected to the welding point.

[0106] If the connection status of both ends of the target circuit indicates that one end of the target circuit is connected to an electrical appliance and the other end is connected to INLINE, S2220 is executed to determine whether the circuit current is equal to the rated current of the electrical appliance.

[0107] If the connection status of both ends of the target circuit indicates that one end of the target circuit is connected to an electrical appliance and the other end is connected to a fuse box, S2230 is executed to determine whether the circuit current is equal to the rated current of the electrical appliance.

[0108] If the connection status of both ends of the target circuit indicates that one end of the target circuit is connected to an electrical appliance and the other end is grounded, S2240 is executed to determine whether the circuit current is equal to the rated current of the electrical appliance.

[0109] If the connection status of both ends of the target circuit indicates that one end of the target circuit is connected to the fuse box and the other end is connected to the INLINE, S2310 is executed to determine whether the circuit current is equal to the INLINE current, where the INLINE current is equal to the rated current of the electrical appliance connected to the INLINE.

[0110] If the connection status of the two ends of the target circuit indicates that one end of the target circuit is connected to the fuse box and the other end is connected to the welding point, execute S2320 to determine whether the circuit current is equal to the welding point current, where the welding point current is equal to the sum of the rated currents of the electrical appliances connected to the welding point.

[0111] If the connection status of both ends of the target loop indicates that one end of the target loop is grounded and the other end is connected to INLINE, S2330 is executed to determine whether the loop current is equal to the INLINE current, where the INLINE current is equal to the rated current of the electrical appliance connected to INLINE.

[0112] If the connection status at both ends of the target loop indicates that one end of the target loop is grounded and the other end is connected to a welding point, execute S2340 to determine whether the loop current is equal to the welding point current, where the welding point current is equal to the sum of the rated currents of the electrical appliances connected to the welding point.

[0113] If the connection status at both ends of the target loop indicates that both ends of the target loop are connected to INLINE, execute S2351 to determine whether there is current at the other end of INLINE1 (i.e., the first INLINE). If so, execute S2352; if not, execute S2353; S2352 determines whether the loop current is equal to the current of INLINE1, where the current of INLINE1 is equal to the rated current of the electrical appliance connected to INLINE1; S2353 determines whether the loop current is equal to the current of INLINE2 (i.e., the second INLINE), where the current of INLINE2 is equal to the rated current of the electrical appliance connected to INLINE2.

[0114] If the connection status at both ends of the target circuit represents that one end of the target circuit is connected to the welding point and the other end is connected to the INLINE, execute S2361 to determine whether the target circuit is the main circuit of the welding point. If so, execute S2362, if not, execute S2363; S2362, determine that the loop current is equal to the welding point current, where the welding point current is equal to the sum of the rated currents of the electrical appliances in all circuits connected to the welding point; S2363, determine that the loop current is equal to the sum of the welding point current and the INLINE current, that is, the sum of the rated currents of the electrical appliances in all circuits connected to the welding point and the rated currents of the electrical appliances connected to the INLINE.

[0115] In some embodiments, in order to more accurately determine the rated current of the electrical appliance, the loop information may further include a target electrical appliance identifier of the electrical appliance, and the electrical appliance may include electrical appliances in N loops connected to the target loop and at least one of the electrical appliances in the target loop, where N may be a non-negative integer;

[0116] Get the rated current of the electrical appliance, which may include:

[0117] According to a preset correspondence between the electrical appliance identification and the rated current, the rated current corresponding to the target electrical appliance identification is determined as the rated current of the electrical appliance.

[0118] Here, the electrical appliances may include but are not limited to the first electrical appliance, the second electrical appliance, the third electrical appliance, the fourth electrical appliance, the electrical appliances in the first circuit, the electrical appliances in the second circuit, the electrical appliances connected to the third object, the electrical appliances connected to the first INLINE, the electrical appliances connected to the second INLINE, and at least one electrical appliance connected to the welding point, and the rated currents of these electrical appliances can be determined based on a preset correspondence between the electrical appliance identification and the rated current.

[0119] Specifically, the loop information may be a wiring harness loop information table, which may be obtained by identifying a pre-drawn circuit diagram, and the wiring harness loop information table may include but is not limited to information such as wire diameter, electrical appliance name, PIN number, terminal model, etc. Among them, a unique electrical appliance can be determined by the electrical appliance name and PIN number, so the electrical appliance identifier may be the electrical appliance name and PIN number.

[0120] The preset correspondence between the electrical appliance identification and the rated current can be an electrical appliance interface information table, which can include information such as the electrical appliance name, PIN pin number, PIN pin current, terminal plating, etc. corresponding to multiple electrical appliances.

[0121] By matching the electrical appliance name and PIN number in the wiring harness loop information table with the electrical appliance name and PIN number in the electrical appliance interface information table, it is possible to determine the electrical appliance that matches the electrical appliance name and PIN number in the wiring harness loop information table from the multiple electrical appliances included in the electrical appliance interface information table, and then determine the PIN current of the electrical appliance, which is the rated current of the electrical appliance.

[0122] In this way, the rated current of the electrical appliance can be determined more accurately through the preset corresponding relationship between the electrical appliance identification and the rated current.

[0123] In relation to S120 , the preset corresponding relationship between the temperature and the rated current may be the corresponding relationship between the target terminal and the target wire diameter.

[0124] Here, a terminal current carrying database can be established in advance, and the terminal current carrying database can store the preset correspondence between the temperature corresponding to different terminals under different wire diameters and the rated current carrying. The data in the terminal current carrying database can be manually input by the user, or it can be obtained by automatically identifying the terminal current carrying curve image and automatically extracting the rated current carrying of the terminal at different temperatures.

[0125] For example, the terminal current carrying curve image can be as follows Figure 3 As shown, the horizontal axis represents the ambient temperature of the terminal in degrees Celsius, and the vertical axis represents the rated current of the terminal in amperes. The rated current corresponding to different wire diameters and temperatures of the terminal is automatically extracted based on the terminal current curve, and the terminal current data can be obtained as shown in Table 1.

[0126] Table 1-Terminal current carrying data

[0127]

[0128] Specifically, the target terminal in the loop information may be an identifier of the target terminal, and the identifier of the target terminal may be a terminal model, such as a terminal part number. A unique set of preset correspondences between temperature and rated current may be determined based on the target terminal and the target wire diameter, and then the target rated current corresponding to the preset temperature may be determined based on the set of preset correspondences.

[0129] Exemplarily, the target terminal is a terminal with a part number of AAA, and the target wire diameter is 1 mm. In this way, the corresponding data of the temperature and the rated current in the row where the adapted wire diameter is 1 mm in Table 1 can be found. If the preset temperature is 20°C, the rated current of 20A corresponding to 20°C can be found from the rated current in the row where the adapted wire diameter is 1 mm. Therefore, the target rated current can be determined to be 20A.

[0130] In S130, after the loop current of the target loop is obtained and the target rated current of the target terminal is determined, the target terminal can be calibrated, and the calibration result of the target terminal can be obtained by judging whether the target rated current is less than the loop current.

[0131] Here, the verification result can be a verification failure or a verification success. When the verification result is a verification failure, it indicates that the target rated current is less than the loop current. When the verification result is a verification success, it indicates that the target rated current is not less than the loop current.

[0132] Specifically, if the target rated current is less than the loop current, the verification result of the target terminal is a verification failure, and if the target rated current is not less than the loop current, the verification result of the target terminal is a verification success.

[0133] In some implementations, in order to facilitate the user to promptly find the terminal that has failed the calibration, after S130, the method may further include:

[0134] When the calibration result indicates that the target rated current is less than the loop current, a prompt message is output to indicate that the calibration of the target terminal has failed.

[0135] Here, the prompt information can be used to prompt that the target terminal verification fails.

[0136] Specifically, if the target rated current is less than the loop current, it indicates that the calibration has failed. When the calibration result of the target terminal indicates that the calibration has failed, a prompt message may be output to prompt the user that the calibration of the target terminal has failed.

[0137] Exemplarily, a verification result list may be output, and the verification result list may include verification results of a plurality of terminals, wherein terminals that fail verification may be marked with a preset mark to indicate that the terminal has failed verification.

[0138] In this way, by outputting a prompt message when the verification result indicates that the target rated current is less than the loop current, the target terminal verification fails, so that the user can find the terminal that failed the verification in time and take corresponding measures in time.

[0139] In order to better describe the entire solution, based on the above embodiments, a specific example is given. Figure 4 As shown, the method may include S401 - S411 , which are explained in detail below.
