[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] In one embodiment, Figure 1 As shown, a method for determining gas emission is provided. This embodiment uses the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0040] S110, obtaining driving data of the target vehicle within a current preset time period.

[0041] The target vehicle can be understood as a vehicle for which gas emissions need to be measured, and the target vehicle can be a passenger car or a truck, etc. This application does not impose any restrictions on the type of the target vehicle. The duration of the current preset period can be set by the technician as needed. For example, the duration of the current preset period can be set to 5 minutes.

[0042] The driving data may include at least one of vehicle speed, engine speed and actual load.

[0043] In an optional embodiment, the original driving data of the target vehicle at a preset collection time in the current preset time period can be obtained; the original driving data is verified to remove invalid and abnormal data to ensure the accuracy and completeness of the data; the original driving data is sorted to obtain the driving data. Among them, the data sorting of the original driving data may include: encapsulating the original driving data into a target vehicle object, and the target vehicle object organizes the data in the form of key-value pairs. Exemplarily, the driving data can be specifically expressed as "{vehicle speed: 25; engine speed: 1200; actual load: 0.85}". Exemplarily, the unit of vehicle speed can be km / h; the unit of engine speed can be revolutions per minute; the unit of actual load can be tons.

[0044] In another optional embodiment, the original driving data of the target vehicle at multiple preset collection moments in the current preset time period can be obtained; the original driving data is verified to remove invalid and abnormal data to ensure the accuracy and completeness of the data; for the original driving data of the same data type, the average driving data of the original driving data is determined; and the different average driving data are sorted to obtain the driving data. Exemplarily, the original driving data for the data type of "vehicle speed" includes: 25km / h, 30km / h and 35km / h, so it can be determined that the average driving data of the original driving data is 30km / h. Similarly, the average driving data for the engine speed and the average driving data for the load can be determined. Sorting the different average driving data can include: encapsulating the different average driving data into a target vehicle object, and the target vehicle object organizes the data in the form of key-value pairs.

[0045] S120. Adjust the initial emission factor of the target vehicle according to the driving data to obtain a target emission factor; the initial emission factor is determined by vehicle parameters of the target vehicle.

[0046] The vehicle parameters of the target vehicle may include at least one of a vehicle model, an engine model, and a displacement.

[0047] In an optional embodiment, a first mapping relationship between the target vehicle and the corresponding initial emission factor under different vehicle parameters may be pre-established, so as to quickly determine the corresponding initial emission factor according to the vehicle parameters of the target vehicle through the first mapping relationship.

[0048] In an optional embodiment, multiple preset conditions can be pre-constructed, and each preset condition corresponds to a preset adjustment data. When the driving data meets the corresponding preset conditions, the initial emission factor is adjusted according to the preset adjustment data of the corresponding preset conditions. It should be noted that the preset conditions and the corresponding preset adjustment data can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any limitation on this.

[0049] Furthermore, each preset condition may be integrated into a rule engine of the system, and the rule engine performs a comparison between the driving data and the preset conditions.

[0050] Furthermore, the pre-built multiple preset conditions can be added, deleted or modified to update the preset conditions. It can be understood that in the process of determining the gas emission, the driving data is compared with the updated preset conditions, and when the driving data meets the corresponding updated preset conditions, the initial emission factor is adjusted according to the preset adjustment data of the corresponding preset conditions.

[0051] Furthermore, rule weights can be assigned to different preset conditions; accordingly, in the process of comparing the preset conditions with the driving data, the comparison between the preset conditions and the driving data can be performed in the order of the rule weights from large to small, so as to avoid comparison conflicts in the rule engine during the comparison process.

[0052] S130. Determine the gas emission of the target vehicle within the current preset time period according to the target emission factor.

[0053] In an optional embodiment, the gas emissions of the target vehicle in the current preset time period are determined according to the target emission factor, including: obtaining the fuel consumption and mileage of the target vehicle in the current preset time period; determining the gas emissions of the target vehicle in the current preset time period according to the fuel consumption, mileage and target emission factor.

[0054] In an optional embodiment, determining the gas emissions of the target vehicle in the current preset time period based on fuel consumption, mileage and target emission factors may include: determining a baseline gas emissions of the target vehicle in the current preset time period based on fuel consumption, mileage and target emission factors; obtaining driving environment data of the target vehicle in the current preset time period; determining an environmental correction coefficient based on the driving environment data; and correcting the baseline gas emissions based on the environmental correction coefficient to obtain the gas emissions of the target vehicle in the current preset time period.

[0055] Alternatively, the gas emissions can be determined using the following formula:

[0056] E=m*f*D*k;

[0057] Among them, E represents gas emissions; m represents the target emission factor; f represents fuel consumption; D represents mileage; and k represents the environmental correction factor.

[0058] Optionally, the driving environment data may include at least one of the ambient temperature and ambient humidity. Accordingly, a second mapping relationship between different driving environment data and corresponding environmental correction coefficients may be established in advance, so as to quickly determine the corresponding environmental correction coefficient according to the driving environment data of the target vehicle during the current preset time period, thereby correcting the baseline gas emissions. It should be noted that the environmental correction coefficients of different driving environment data may be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any limitation on this.

[0059] For ease of understanding, take the driving environment data including the ambient temperature as an example. If the ambient temperature drops, the target vehicle will increase the fuel consumption, resulting in a larger determined baseline gas emission, so the value of the environmental correction coefficient can be reduced to correct the baseline gas emission. Similarly, if the ambient temperature rises, the target vehicle will reduce the fuel consumption, resulting in a smaller determined baseline gas emission, so the value of the environmental correction coefficient can be increased to correct the baseline gas emission.

[0060] Exemplarily, a reference ambient temperature can be predetermined, and the environmental correction coefficient of the reference ambient temperature is set to 1. On this basis, each time the preset temperature is lowered, the environmental correction coefficient decreases by the set coefficient value; conversely, each time the preset temperature is increased, the environmental correction coefficient increases by the set coefficient value, thereby obtaining environmental correction coefficients corresponding to different ambient temperatures. The preset temperature and the set coefficient value can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not make any limitation on this. Exemplarily, the set coefficient value is 0.03.

[0061] In an optional embodiment, after determining the gas emission of the target vehicle in the current preset time period, the method further includes: matching the gas emission with the target vehicle identification, the current preset time period, the driving route and other information and storing them in a database. The target vehicle identification may be the license plate number of the target vehicle.

[0062] In an optional embodiment, the gas emissions in all preset time periods may be accumulated to obtain a cumulative gas emission amount.

[0063] The above-mentioned method, device, equipment, medium and program product for determining gas emissions can reflect the driving status of the target vehicle in the current preset period by acquiring the driving data of the target vehicle in the current preset period, and provide a basic basis for adjusting the initial emission factor. By adjusting the initial emission factor of the target vehicle according to the driving data, the target emission factor is obtained, and the gas emissions of the target vehicle in the current preset period are determined according to the target emission factor, which realizes the comprehensive determination of the gas emissions of the target vehicle from the two dimensions of the static parameter dimension and the dynamic driving data of the target vehicle, thereby improving the accuracy of the determination. At the same time, the above-mentioned process for determining the gas emissions is relatively simple and convenient for implementation and application.

[0064] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the steps for determining the target emission factor are refined.

[0065] See also Figure 2 The steps for determining the target emission factors shown include:

[0066] S210: Determine a target preset condition satisfied by the driving data from different preset conditions.

[0067] In an optional embodiment, the driving data includes vehicle speed and engine speed; accordingly, different preset conditions include at least one of the following: the vehicle speed is less than a first preset vehicle speed, and the engine speed is less than the first preset engine speed; the vehicle speed is not less than a second preset vehicle speed, and the engine speed is not less than a second preset engine speed; wherein the second preset vehicle speed is greater than the first preset vehicle speed, and the second preset engine speed is greater than the first preset engine speed.

[0068] It should be noted that the first preset vehicle speed, the second preset vehicle speed, the first preset engine speed and the second preset engine speed can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any restrictions on this. For example, the first preset vehicle speed can be 30km / h, the second preset vehicle speed can be 50km / h, the first engine speed can be 1000 rpm, and the second engine speed can be 1500 rpm.

[0069] In an optional embodiment, the driving data includes the actual load; accordingly, the different preset conditions include at least one of the following: the actual load is less than the first preset load; the first preset load is determined by the rated load of the target vehicle and the first preset ratio; the actual load is not less than the second preset load; the second preset load is determined by the rated load of the target vehicle and the second preset ratio; wherein the second preset ratio is greater than the first preset ratio.

[0070] It should be noted that the first preset ratio and the second preset ratio can be set by technicians according to needs or experience, or determined through a large number of experiments, and this application does not impose any limitation on this. For example, the first preset ratio can be 30%, and the second preset ratio can be 80%.

[0071] S220: Obtain preset adjustment data corresponding to the target preset condition.

[0072] Each target preset condition corresponds to preset adjustment data, which is used to adjust the initial emission factor of the target vehicle.

[0073] For example, taking the target vehicle as a transport truck, when the vehicle speed is less than 30 km / h and the engine speed is less than 1000 rpm, the target vehicle is idling, resulting in incomplete engine combustion and increased actual gas emissions from the target vehicle. At this time, the preset adjustment data corresponding to the preset condition can be set to 1.2.

[0074] For example, taking the target vehicle as a transport truck, when the vehicle speed is not less than 50 km / h and the engine speed is not less than 1500 rpm, the engine combustion of the target vehicle is relatively complete. At this time, the preset adjustment data corresponding to the preset condition can be set to 0.9.

[0075] For example, when the actual load of the target vehicle is not less than 80% of the rated load, the engine load of the target vehicle will be higher, affecting the sufficiency of engine combustion. At this time, the preset adjustment data corresponding to the preset condition can be set to 1.5.

[0076] For example, when the actual load of the target vehicle is less than 30% of the rated load, the engine load of the target vehicle is relatively low. At this time, the preset adjustment data corresponding to the preset condition can be set to 0.7.

[0077] S230. Adjust the initial emission factor of the target vehicle according to preset adjustment data to obtain a target emission factor.

[0078] The adjustment type of the preset adjustment data may include a coefficient type or an increment type. When the adjustment type of the preset adjustment data is a coefficient type, the target emission factor is obtained by multiplying the initial emission factor by each preset adjustment data. When the adjustment type of the preset adjustment data is an increment type, the target emission factor is obtained by adding the initial emission factor to each preset adjustment data.

[0079] For the sake of convenience, according to the preset adjustment data provided in the previous example, and taking the preset adjustment data as the coefficient type as an example, if the speed of the target vehicle is 60km / h, the engine speed is 1600 rpm, and the actual load of the target vehicle is 28% of the rated load, then the target emission factor m can be expressed as: 0.9*0.7*m c ;m c represents the initial emission factor.

[0080] For ease of understanding, in an optional embodiment, taking a truck as an example, the target vehicle is combined with Figure 3A The schematic diagram of the system for determining the gas emission amount is shown for explanation.

[0081] like Figure 3A As shown, after the system is started, the rule engine responds to the task of loading the rule base and queries the rule base from the database, where different preset conditions are stored; the rule engine parses different preset conditions from the rule base and verifies the validity of each preset condition; the data acquisition module collects the original data (i.e., original driving data) of the target vehicle in the current preset period and sends the original data to the data preprocessing module. The data preprocessing module cleans, formats and encapsulates the original data and provides the "truck running status" object (i.e., driving data) to the rule engine; the rule engine checks and determines the target preset conditions satisfied by the driving data; according to the preset adjustment data corresponding to the target preset conditions, the initial emission factor adjustment action is performed in sequence; in the process of judging the preset conditions, the updated preset conditions (i.e., the latest rules) are compared with the driving data to avoid logical conflicts; the adjusted target emission factor is sent to the emission calculation module.

[0082] The emission calculation module determines the baseline gas emission of the target vehicle in the current preset period according to the target emission factor, fuel consumption and mileage; obtains the driving environment data of the target vehicle in the current preset period; determines the environmental correction coefficient according to the driving environment data; corrects the baseline gas emission according to the environmental correction coefficient to obtain the gas emission of the target vehicle in the current preset period; the emission calculation module sends the gas emission to the result processing module;

[0083] The result processing module uploads the result processing module to the database, and receives confirmation storage completion information fed back by the database.

[0084] In an exemplary embodiment, Figure 3B As shown, another method for determining gas emissions is provided, comprising the following steps:

[0085] S310, obtaining driving data of the target vehicle within the current preset time period.

[0086] S320: Determine a target preset condition satisfied by the driving data from different preset conditions.

[0087] S330: Obtain preset adjustment data corresponding to the target preset condition.

[0088] S340. According to preset adjustment data, the initial emission factor of the target vehicle is adjusted to obtain a target emission factor; the initial emission factor is determined by vehicle parameters of the target vehicle.

[0089] S350: Obtain the fuel consumption and mileage of the target vehicle in the current preset time period.

[0090] S360: Determine the baseline gas emissions of the target vehicle within the current preset time period based on the fuel consumption, mileage and target emission factor.

[0091] S370: Obtain driving environment data of the target vehicle within the current preset time period.

[0092] S380: Determine an environment correction coefficient according to the driving environment data.

[0093] S390. Correct the reference gas emission according to the environmental correction coefficient to obtain the gas emission of the target vehicle in the current preset time period.

[0094] The detailed technical contents of the above steps S310 - S390 have been recorded in the above examples and will not be repeated here.

[0095] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
