Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising 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, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

In practical applications, including but not limited to this, no specific limitation is made here and it may be determined according to the sales area of ​​the vehicle.

[0023] The sales area of ​​a vehicle refers to the geographical area where the vehicle's sales coverage or target market is located, such as City B in Country A.

[0024] If the sales area of ​​the vehicle is not in the country or region of the manufacturer of the vehicle, the vehicle's region refers to the country or region of the vehicle. For example, if the sales area of ​​the vehicle is City B in Country A and the manufacturer of the vehicle is Country C, then the vehicle's region is Country A.

[0025] If the sales area of ​​the vehicle is in the country or region where the vehicle manufacturer is located, the region where the vehicle is located refers to any level of administrative division under the country or region where the vehicle is located. For example, if the sales area of ​​the vehicle is City B in Country A and the country where the vehicle manufacturer is located is Country A, then the region where the vehicle is located is City B.

[0026] It should be noted that, usually, the sales area of ​​the vehicle is set in the cockpit domain controller in the vehicle through the super management authority, so the sales area of ​​the vehicle can be obtained from the cockpit domain controller in the vehicle.

[0027] S120. Determine the carbon emission coefficient of the area where the vehicle is located based on the life cycle greenhouse gas emission index and the electricity energy structure of the area where the vehicle is located.

[0028] The life cycle greenhouse gas emission index refers to the life cycle average carbon emissions of various electricity sources, that is, the average carbon emissions of various electricity sources during their respective life cycles.

[0029] For example, the life cycle greenhouse gas emission indicators are shown in the following table:

[0030] It should be noted that the above table only shows the currently commonly used electricity sources. In practical applications, other electricity sources may also be included. No specific limitation is made here. It can be determined according to the specific situation and is within the scope of protection of this application. In addition, the life cycle average carbon emissions of various electricity sources shown in the above table, that is, the values ​​on the right side of the above table, are only the currently measured values.

Therefore, the carbon emission reduction detection method can detect the carbon emission reduction of the vehicle.

[0043] Since the parameters required in this carbon emission reduction detection method include life cycle greenhouse gas emission indicators, the electricity energy structure of the vehicle's area, the global average electricity energy structure and the vehicle's discharge amount, and in actual applications, the life cycle greenhouse gas emission indicators, the electricity energy structure of the vehicle's area, the global average electricity energy structure and the vehicle's discharge amount can all be directly obtained, so this carbon emission reduction detection method can be put into practical application.

[0044] In summary, the carbon emission reduction detection method can realize the practical application of vehicle carbon emission reduction detection.

[0045] In addition, in this embodiment, the area where the vehicle is located may refer to the country where the vehicle is located or the region where the vehicle is located, or it may refer to any level of administrative unit under the country where the vehicle is located or the region where the vehicle is located. Therefore, the carbon emission reduction detection method can be compatible with different countries or regions, or different administrative units under the country or region to which the vehicle belongs.

Of course, it is also possible to obtain the average emission factor of the regional power grid in advance, and when the carbon emission coefficient of the area where the vehicle is located is needed, look up the table based on the average emission factor of the regional power grid to obtain the carbon emission coefficient of the area where the vehicle is located. It should be noted that if the average emission factor of the regional power grid is obtained in advance and stored, the stored average emission factor of the regional power grid needs to be updated regularly.

[0093] In this embodiment, since the area where the vehicle is located is the area where the vehicle manufacturer is located, the carbon emission coefficient of the area where the vehicle is located can be directly obtained, so there is no need to go through step S120, thereby optimizing the specific process of the carbon emission reduction detection method.

[0094] The above is only a specific implementation method of the vehicle carbon emission reduction detection method. In practical applications, including but not limited to this, no specific limitation is made here. It can be determined according to the specific situation and is within the scope of protection of this application.

[0095] Another embodiment of the present application provides another specific implementation method of the vehicle carbon emission reduction detection method, and its specific process can be found in Figure 8 ( Figure 8 Only in Figure 7 This embodiment further includes the following steps after step S140 in any of the above embodiments: S810: Display the carbon emission reduction of the vehicle on a display screen of the vehicle, and / or upload the carbon emission reduction of the vehicle to the cloud.

[0096] It should be noted that displaying the vehicle's carbon emission reduction on a display screen in the vehicle and uploading the vehicle's carbon emission reduction to the cloud are already very mature in the existing technology and will not be described in detail here.

[0097] The above is only a specific implementation method of the vehicle carbon emission reduction detection method. In practical applications, including but not limited to this, no specific limitation is made here. It can be determined according to the specific situation and is within the scope of protection of this application.

[0098] Another embodiment of the present application provides a specific implementation of step S110, and the specific process is as follows: Fig. 9 As shown, the specific steps include: S910: Obtain the current position of the vehicle.

[0099] Specifically, the vehicle's GPS location information is obtained through the vehicle's intelligent driving domain controller to obtain the vehicle's current location.

[0100] It should be noted that how the intelligent driving domain controller obtains the GPS location information of the vehicle is already very mature in the existing technology and will not be described in detail here.

[0101] S920: Determine the area where the vehicle is located according to the current position of the vehicle.

[0102] It should be noted that determining the area where the vehicle is located based on the current position of the vehicle is already very mature in the prior art and will not be described in detail here.

[0103] In this embodiment, the area where the vehicle is located is determined based on the current position of the vehicle, so that the determined area where the vehicle is located is more accurate, and thus the determined carbon emission reduction amount of the vehicle is more accurate.

[0104] The above is only a specific implementation of step S110. In practical applications, including but not limited to this, no specific limitation is made here and it may be determined according to the specific situation, all of which are within the protection scope of this application.

[0105] Another embodiment of the present application provides a specific implementation of step S110, and the specific process is as follows: Fig.10 As shown, the specific steps include: S930: Obtain the sales region of the vehicle.

[0106] It should be noted that the definition of the vehicle sales area and how to obtain the vehicle sales area have been described in detail above and will not be repeated here.

[0107] S940: The sales area of ​​the vehicle is used as the area where the vehicle is located.

[0108] In this embodiment, since the vehicle's sales area is directly stored in the vehicle's cabin domain controller and is not restricted by GPS signals and networks, using the vehicle's sales area as the area where the vehicle is located can reduce the impact of GPS signal and network instability on the carbon emission reduction detection method and improve the stability of the vehicle's carbon emission reduction detection.

[0111] The power domain controller 10 can be used to be electrically connected to the charging device 40 to obtain the charging amount of the vehicle at each moment in the current charging process from the charging device 40 .

[0112] The power domain controller 10 is used to execute the vehicle carbon emission reduction detection method provided in any of the above embodiments of the present application. The power domain controller 10 is also used to monitor the battery of the vehicle in real time.

[0113] It should be noted that the real-time monitoring of the battery of the vehicle by the power domain controller 10 is already very mature in the prior art and will not be described in detail here.
