[0003] In the process of developing this invention, the inventors discovered the following shortcomings in the existing technology: Currently, conventional vehicle emission control technologies mainly focus on reducing the inherent pollutant emissions of the vehicle. However, engine emissions vary significantly under different operating conditions. Therefore, optimizing engine operating conditions can substantially reduce the final pollutant emissions of the vehicle. However, the corresponding carbon soot emission levels of a vehicle engine under different operating conditions cannot be determined, making it difficult to reasonably control pollutant emissions. Summary of the Invention

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0023] Example 1

[0024] Figure 1 The flowchart of a method for determining carbon emission levels is provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the carbon emission levels of a target vehicle are determined in real time. The method can be executed by a carbon emission level determining device, which can be implemented in hardware and / or software.

[0025] Correspondingly, such as Figure 1 As shown, the method includes:

[0026] S110. During the operation of the target vehicle, obtain the real-time engine description information of the target vehicle.

[0027] The real-time engine description information includes engine operating conditions, engine coolant temperature, and fuel injection mode.

[0028] Among them, real-time engine description information can be information that describes the vehicle's engine in real time.

[0029] Specifically, real-time engine description information can include engine operating conditions, engine coolant temperature, and fuel injection mode. Engine operating conditions can describe the engine speed and engine load. Engine coolant temperature can describe the engine's coolant temperature status.

[0030] In this embodiment, since the engine needs to warm up quickly when the engine coolant temperature is below 0°C, its emission levels should not be considered by the driver. Therefore, emission calculation and alerts should begin when the engine coolant temperature is above 0°C.

[0031] In addition, fuel injection modes can include engine single injection mode and engine dual injection mode.

[0032] S120. Calculate the real-time carbon emission level based on the engine operating conditions, engine coolant temperature, and fuel injection mode.

[0033] Among them, the real-time carbon emission level can be the carbon emission level of the target vehicle at the target time.

[0034] Optionally, the engine operating conditions include engine speed and engine load. The step of calculating the real-time carbon emission level based on the engine operating conditions, engine coolant temperature, and fuel injection mode includes: determining the initial carbon emission concentration based on engine speed and engine load using a preset first correction coefficient mapping table; determining the coolant temperature correction coefficient based on the engine coolant temperature and fuel injection mode using a preset second correction coefficient mapping table; and calculating the real-time carbon emission level based on the initial carbon emission concentration and the coolant temperature correction coefficient.

[0035] Here, engine speed can describe the current engine speed. Engine load can describe the current engine load.

[0036] Specifically, the first correction factor mapping table can be a table that determines the initial soot emission concentration based on engine speed and engine load. That is, once the engine speed and engine load are determined, the initial soot emission concentration can be determined using the first correction factor mapping table. The initial soot emission concentration can be the soot emission concentration initially determined based on the engine operating conditions.

[0037] Additionally, the second correction factor mapping table can be a table that determines the coolant temperature correction factor based on the engine coolant temperature and fuel injection mode. That is, once the engine coolant temperature and fuel injection mode are determined, the coolant temperature correction factor can be determined using the second correction factor mapping table. The coolant temperature correction factor can be a coefficient determined based on the engine coolant temperature and fuel injection mode, and it changes as the engine coolant temperature and fuel injection mode change.

[0038] In this embodiment, when the real-time carbon emission level is calculated based on the real-time engine description information, the calculated real-time carbon emission level is more consistent with the engine conditions, thus improving the accuracy of determining the real-time carbon emission level.

[0039] Optionally, calculating the real-time soot emission level based on the initial soot emission concentration and the water temperature correction factor includes: acquiring vehicle exhaust flow and vehicle speed in real time; and calculating the real-time soot emission level based on the initial soot emission concentration, the water temperature correction factor, the vehicle exhaust flow, and the vehicle speed using a formula. The real-time carbon emission level Mf_PM is calculated; where Em_PM represents the initial carbon emission concentration; V_EXH represents the vehicle exhaust flow rate; K represents the water temperature correction factor; and V represents the vehicle speed.

[0040] Specifically, vehicle exhaust flow and vehicle speed can be acquired in real time and used to calculate real-time carbon emission levels.

[0041] In this embodiment, it is necessary to obtain the vehicle exhaust flow rate and vehicle speed, and then, based on the previously calculated initial soot emission concentration and water temperature correction coefficient, apply the above formula. To jointly determine the real-time carbon emission level.

[0042] The advantages of this setting are: it makes the calculated real-time carbon emission level more accurate, allows for more timely emission of carbon soot, reduces pollutant emissions, improves vehicle driving safety, and enhances the user's driving experience.

[0043] S130. If the real-time carbon emission level exceeds the preset real-time carbon emission level threshold, an early warning will be issued through visualization.

[0044] The real-time carbon emission level threshold can be a pre-set real-time carbon emission level threshold. In other words, if the driver's real-time carbon emission level exceeds the real-time carbon emission level threshold at the current moment, the driver needs to change driving style to reduce pollutant emissions.

[0045] In this embodiment, the driver needs to be alerted when the real-time carbon emission level exceeds the real-time carbon emission level threshold. Specifically, on the vehicle display screen, a green bar chart can be used to indicate that the real-time carbon emission level does not exceed the real-time carbon emission level threshold, and a red bar chart can be used to indicate that the real-time carbon emission level exceeds the real-time carbon emission level threshold.

[0046] Optionally, after calculating the real-time carbon emission level based on the engine operating conditions, engine coolant temperature, and fuel injection mode, the method further includes: obtaining the current single-run time of the target vehicle after the target vehicle's operation ends; and calculating the real-time carbon emission level based on the current single-run time and the real-time carbon emission level using a formula. The single-run carbon emission level Am_PM is calculated; where d represents the current single-run time; if the single-run carbon emission level exceeds the preset single-run carbon emission level threshold, an early warning is issued through visualization.

[0047] The current single-run time can be the time used for the target vehicle's current driving. The single-run carbon emission level can be the carbon emission level corresponding to the target vehicle's current driving process. The single-run carbon emission level threshold can be a pre-set single-run carbon emission level threshold.

[0048] In this embodiment, it is necessary to obtain the time taken by the target vehicle during this driving, and then calculate the single carbon emission level based on the calculated real-time carbon emission level.

[0049] For example, if the current single driving session lasts 2 hours and the real-time carbon emission level is A, according to the formula... The level of carbon emissions per incident can be determined.

[0050] Optionally, after calculating the single carbon emission level, the method further includes: obtaining the previous cumulative carbon emission level of the target vehicle; calculating the current cumulative carbon emission level based on the single carbon emission level and the previous cumulative carbon emission level; and if the current cumulative carbon emission level exceeds a preset current cumulative carbon emission level threshold, then a warning signal is fed back to the user.

[0051] The preceding cumulative carbon emissions level can be the cumulative carbon emissions level prior to the current driving of the target vehicle. The current cumulative carbon emissions level can be the cumulative carbon emissions level after the current driving of the target vehicle. The current cumulative carbon emissions level threshold can be a pre-set cumulative carbon emissions level threshold.

[0052] In this embodiment, it is necessary to determine whether the current cumulative carbon emission level exceeds a threshold. If it does, a warning signal needs to be sent to the user so that the user can burn carbon in time and improve the vehicle's safe driving performance.

[0053] For example, assuming the current cumulative carbon emission level threshold is 5g, if the current cumulative carbon emission level is 5.2g, the user is warned that the particulate filter needs to be regenerated, that is, the user can choose a time or place to burn carbon.

[0054] Optionally, after the step of feeding back a warning signal to the user if the current cumulative carbon emission level exceeds a preset current cumulative carbon emission level threshold, the method further includes: upon receiving a carbon emission command, instructing the engine to perform a self-burning operation according to a preset self-burning carbon condition to automatically reduce the current cumulative carbon emission level; wherein, the self-burning carbon condition is achieved by cyclically controlling the engine speed, engine load, and engine fuel cut-off.

[0055] Among these, the carbon emission command can be a user-issued instruction to the vehicle to emit carbon smoke. The self-burning carbon mode can be achieved by cyclically controlling engine speed, engine load, and engine fuel cut-off.

[0056] In this embodiment, if the current cumulative carbon emission level exceeds the preset current cumulative carbon emission level threshold, and the user receives an alert, the user can choose a time or location to perform carbon burning.

[0057] Additionally, users can press the one-button carbon burning control switch on the target vehicle. Upon receiving a carbon emission command, the target vehicle switches to self-burning carbon mode and performs self-burning carbon operation to automatically reduce the current cumulative carbon emission level.

[0058] The advantage of this setup is that it eliminates the need for users to manually burn carbon in the vehicle over a certain period of time. Once a carbon emission command is received, the vehicle automatically burns carbon, saving time, increasing the flexibility of automatic carbon burning, and improving the user's driving experience.

[0059] Optionally, before acquiring the real-time engine description information of the target vehicle during its operation, the method further includes: acquiring multiple historical engine operating conditions, wherein the historical engine operating conditions include historical engine speed and historical engine load; analyzing each first parameter combination pair composed of the historical engine speed and historical engine load to determine each historical initial carbon emission concentration, and constructing a first correction coefficient mapping table based on each historical initial carbon emission concentration.

[0060] Here, "historical engine operating conditions" can be historical operating condition data describing the vehicle's engine. "Historical engine speed" can be historical engine speed data obtained from the vehicle. "Historical engine load" can be historical engine load data obtained from the vehicle. "First parameter combination pair" can be a parameter pair consisting of historical engine speed and historical engine load corresponding to each historical engine operating condition. "Historical initial soot emission concentration" can be the initial soot emission concentration corresponding to the first parameter combination pair.

[0061] In this embodiment, since the initial soot emission concentration is different when the engine speed and engine load are at different values, it is necessary to obtain a large amount of historical engine operating conditions in advance for analysis, further determine the initial soot emission concentration, and build a table to form a mapping relationship.

[0062] Specifically, once the real-time engine speed and real-time engine load are determined, the initial soot emission concentration can be determined based on the established first correction coefficient mapping table.

[0063] Optionally, before acquiring the real-time engine description information of the target vehicle during its operation, the method further includes: acquiring multiple historical engine coolant temperatures and multiple historical fuel injection modes; analyzing each pair of second parameter combinations composed of historical engine coolant temperatures and historical fuel injection modes to determine each historical coolant temperature correction coefficient, and constructing a second correction coefficient mapping table based on each of the historical coolant temperature correction coefficients.

[0064] Here, "historical engine coolant temperature" can be data describing the historical coolant temperature of the vehicle's engine. "Historical injection pattern" can be data describing the historical injection pattern of the vehicle's engine. "Second parameter combination pair" can be a parameter pair consisting of each historical engine coolant temperature and historical injection pattern. "Historical coolant temperature correction factor" can be the coolant temperature correction factor corresponding to the second parameter combination pair.

[0065] In this embodiment, since the engine coolant temperature is at different values ​​and the fuel injection mode is at different modes, the corresponding coolant temperature correction coefficient is also different. It is necessary to obtain a large amount of historical engine coolant temperature and historical fuel injection mode in advance for analysis, further determine the coolant temperature correction coefficient, and build a table to form a mapping relationship.

[0066] Specifically, once the real-time engine coolant temperature and real-time fuel injection mode are determined, the coolant temperature correction coefficient can be determined based on the established second correction coefficient mapping table.

[0067] The advantage of this setup is that by acquiring multiple historical engine operating conditions, historical engine coolant temperatures, and historical fuel injection patterns, the first and second correction coefficient mapping tables can be constructed respectively. This improves the accuracy of determining real-time soot emission levels and simplifies the operation of determining real-time soot emission levels.

[0068] The technical solution of this invention acquires real-time engine description information of the target vehicle during its operation. This real-time engine description information includes engine operating conditions, engine coolant temperature, and fuel injection mode. Based on the engine operating conditions, engine coolant temperature, and fuel injection mode, the real-time carbon emission level is calculated. If the real-time carbon emission level exceeds a preset real-time carbon emission level threshold, a visual warning is issued. This solves the problem of not being able to determine the vehicle's carbon emission level in real time, achieving real-time monitoring of carbon emission levels. This allows for timely alerts to the driver, improving driving safety and reducing vehicle pollutant emissions.

[0072] The real-time carbon emission level calculation module 220 is used to calculate the real-time carbon emission level based on the engine operating conditions, engine coolant temperature, and fuel injection mode.

[0073] The early warning module 230 is used to issue an early warning in a visual manner if the real-time carbon emission level exceeds a preset real-time carbon emission level threshold.
