[0035] The embodiment of the present application provides a method, device, equipment and storage medium for vehicle engine power adaptation, which can adjust the engine power performance and responsiveness in different driving environments, reduce the original soot emission of the engine on the premise of meeting the power demand, reduce the regeneration frequency, reduce the fuel consumption loss brought by the regeneration process, and improve the fuel economy. At the same time, it can improve the driving adaptability of the vehicle to various operating conditions and enhance the driving experience of the driver. To achieve the above technical effects, the general idea of the present application is as follows:

[0036] A method for vehicle engine power adaptation, the method includes the steps:

[0037] S101: Determine whether the route where the target vehicle is currently located is a fixed operation route.

[0038] S102: When the route where the target vehicle is currently located is not a fixed operation route, calculate the condition coefficient of the current route.

[0039] S103: Determine the road condition where the target vehicle is located according to the condition coefficient of the current route, and adaptively adjust the combustion parameters of the vehicle engine.

[0040] The following further describes the embodiments of the present application in detail with reference to the drawings.

[0041] Refer to Figure 1 , Figure 1 As shown in the flowchart of a method for vehicle engine power adaptation provided by the present invention, as Figure 1 shown, the method includes the steps:

[0042] Step S101: Determine whether the route where the target vehicle is currently located is a fixed operation route.

[0043] Specifically, according to the historical operation route of the target vehicle, the repetition degree of the current operation route of the target vehicle is determined. When the route repetition degree of the target vehicle is greater than 70%, it is determined that the route where the target vehicle is currently located is a fixed route. When the route repetition degree of the target vehicle is less than 70%, it is determined that the route where the target vehicle is currently located is a non-fixed route.

[0044] In one embodiment, the fixed route self-learning module (fixed route) uses vehicle positioning and trajectory to perform a full-line condition analysis and identification on vehicles with relatively fixed operation routes. By the average vehicle speed, average throttle opening, and average load of the target vehicle itself at different sections of the operation route, the conditions of different sections under the fixed route are judged. The conditions of different sections include: urban, suburban, and highway. At the same time, according to different average vehicle speeds, average throttle openings, and average loads, these three conditions are smoothly transitioned, and the corresponding engine working modes of the vehicle are allocated to ensure that the vehicle can adaptively adjust in the case of inconsistent power requirements in different sections.

[0045] It should be noted that smooth transition can be understood as follows. When the target vehicle is located between urban and suburban road conditions, by calculating the average value between the two and using the average value to determine the combustion parameters of the target vehicle in urban road conditions and the combustion parameters of the target vehicle in suburban road conditions. For easy understanding, an example is given. If the calculated road condition coefficient of the target vehicle is 0.34, and less than 0.28 is the urban road condition, and equal to 0.47 is the suburban road condition, then according to the proportional conversion, (0.33 - 0.28) / (0.47 - 0.28) = 0.32. Then, for the coefficient 0.33, the corresponding working condition is that the proportion of the suburban working condition and the urban working condition is 32% and 68%. At this time, the interpolation relationship proportion is 68% of the urban working condition combustion parameters plus 32% of the suburban working condition combustion parameters as the final output.

[0046] In one embodiment, when the current route repetition degree of the target vehicle is greater than 70%, the condition coefficient of the fixed route is calculated according to the historical trajectory data of the target vehicle on the vehicle networking platform, and the road condition (urban, suburban, highway) where the target vehicle is located is determined through the condition coefficient of the current route, and the combustion parameters of the vehicle engine are adaptively adjusted.

[0047] In addition, when the average vehicle speeds of different sections of the fixed route are inconsistent due to factors such as road grade, road condition, vehicle congestion, traffic lights, etc., the fixed route self-learning module can decompose the sections with different vehicle speeds into different target conditions (conditions that are smoothly transitioned according to data such as vehicle speed and throttle), and input them into the engine ECU. The ECU obtains the corresponding driving characteristics, air-fuel ratio limit, and external characteristic fuel quantity limit by looking up tables and interpolating in the three road conditions (urban, suburban, highway).

[0048] In one embodiment, when the repeatability of the current route of the target vehicle is less than 70%, the route is determined according to the average statistical results (vehicle speed, throttle, load percentage) of the current vehicle operation route, which is used as the input for the working condition identification of the engine ECU. The ECU obtains the corresponding driving characteristics, air-fuel ratio limit, and full-load fuel quantity limit by looking up tables and interpolating in three road conditions (urban, suburban, and highway).

[0049] It should be noted that for the air-fuel ratio limit: The diesel engine controls the original exhaust smoke and transient response according to the air-fuel ratio limit. During the transient process, the smaller the air-fuel ratio limit, the slower the engine power response, and the less the original carbon smoke is generated. Similarly, to enhance the engine power response, the air-fuel ratio limit can be appropriately relaxed, but the amount of carbon smoke generated during the transient process will increase. For different usage scenarios at the same altitude, the air-fuel ratio limit can be calibrated adaptively to minimize the original exhaust carbon smoke level and increase the regeneration mileage and economy while meeting the power requirements.

[0050] Full-load fuel quantity: The maximum fuel injection quantity allowed at different engine speeds. The full-load fuel quantity determines the output power. The maximum power requirements of the engine are different in different usage scenarios, and the full-load fuel quantity can be changed according to different usage scenarios to meet the required values of the engine output power in different scenarios.

[0051] Driving characteristics: The correspondence between the accelerator pedal and the percentage of the actual throttle opening controlled by the ECU. Changing the driving characteristics can change the actual throttle opening response of the ECU under the same driving behavior of the driver. By changing the driving characteristics in different usage scenarios, the engine throttle response characteristics can be changed without changing the driver's driving behavior.

[0052] Optionally, for the irregular road congestion caused by factors such as temporary construction and accidents, the ECU working condition is corrected through the networked navigation real-time update module.

[0053] In one embodiment, the big data analysis and road network self-learning module (non-fixed route), based on the statistical analysis of vehicle network big data, can classify the road operation conditions of different routes and the same section at different time periods into three categories (urban, suburban, and highway), and the three working conditions can be smoothly transitioned according to conditions such as average vehicle speed, average throttle opening, and average load.

[0054] Optionally, the networked navigation real-time update module corrects the self-learning road condition results of the fixed route self-learning module and the big data analysis and road network self-learning module according to the real-time road congestion condition of the networked navigation.

[0055] In one embodiment, the discrimination of fixed-route and non-fixed-route working conditions can be carried out in two ways: statistical analysis of its own historical data and statistical analysis of big data of the vehicle networking. This can avoid misjudgment of the operating conditions of special vehicles or vehicles in special working conditions. For example, the average speed of a sprinkler truck on the same section of the road is much lower than that of normal operating vehicles, but the route of the sprinkler truck is fixed. Therefore, the working conditions are discriminated based on the statistical analysis of its own historical data, and the working conditions of other vehicles are discriminated by the big data analysis of the vehicle networking and the road network self-learning module, so as to improve the implementation accuracy and scope.

[0056] Step S102: When the route where the target vehicle is currently located is not a fixed operating route, calculate the working condition coefficient of the current route.

[0057] Specifically, when it is determined that the repeatability of the current route of the target vehicle is less than 70%, the current route of the target vehicle is a non-fixed route. Then, according to the ratio among the average speed, average throttle opening, and average load rate of the same type of vehicles on the vehicle networking platform, calculate the working condition coefficient of the route where the target vehicle is currently located.

[0058] For easy understanding, an example is given. The road working conditions are divided into urban, suburban, and highway modules. In the actual look-up table transition, three groups of maps are defined. The urban working condition is 100% economy + weak power, the suburban working condition is 50% economy + 50% power, and the highway working condition is weak economy + strong power. The working condition recognition functions in three different ways are input into the ECU in the form of percentages. The working conditions can be determined by three factors: speed, throttle, and load rate. The determination formula is: determination coefficient = 0.7 * average speed / 80 + 0.2 * average throttle percentage / 100 + 0.1 * average load rate / 100. If the coefficient is less than 0.28, it is determined as the urban working condition; if the coefficient = 0.47, it is determined as the suburban working condition; if the coefficient > 0.85, it is determined as the highway working condition. The corresponding ideal relationships are as follows:

[0059] Urban working condition: average speed is lower than 25 km / h, average throttle distribution is less than 20%, and average load percentage is less than 25%.

[0060] Suburban working condition: average speed is 40 km / h, average throttle distribution is 35%, and average load percentage is 45%.

[0061] Highway working condition: average speed is greater than 80 km / h, average throttle distribution is greater than 45%, and average load percentage is greater than 55%.

[0062] It should be noted that the coefficient formula can be calibrated and adjusted according to different vehicle models, and the definition rule of the determination coefficient can also be calibrated and adjusted according to different vehicle models. The above data is used to describe the calculation process.

[0063] In one embodiment, when the target vehicle is between the urban road condition and the suburban road condition, calculate the average road condition coefficient between the two, and based on the average road condition coefficient, calculate the engine combustion parameters corresponding to the urban road condition and the suburban road condition. For easy understanding, an example is given. If the coefficient is less than 0.28, it is determined as the urban working condition. If the coefficient = 0.47, it is determined as the suburban working condition. If the actually calculated coefficient is 0.34, then according to proportional conversion, (0.33 - 0.28) / (0.47 - 0.28) = 0.32. According to the proportional relationship conversion, it is known that the working condition corresponding to the coefficient 0.33 is that the proportion of the suburban working condition and the urban working condition is 32% and 68%. At this time, the interpolation relationship accounts for 68% of the urban working condition combustion parameters plus 32% of the suburban working condition combustion parameters as the final output.

[0064] Step S103: Determine the road condition of the target vehicle according to the working condition coefficient of the current route, and adaptively adjust the combustion parameters of the vehicle engine.

[0065] Specifically, when the calculated working condition coefficient of the current route of the target vehicle is less than or equal to the first working condition coefficient, it is determined that the current road condition of the target vehicle is the urban road condition, and the combustion parameters of the target vehicle engine are adjusted to the engine combustion parameters corresponding to the preset urban road condition;

[0066] When the working condition coefficient of the current route of the target vehicle is equal to the second working condition coefficient, determine the current suburban road condition of the target vehicle, and adjust the combustion parameters of the target vehicle engine to the engine combustion parameters corresponding to the preset suburban road condition;

[0067] When the working condition coefficient of the current route of the target vehicle is greater than the third working condition coefficient, determine the current highway road condition of the target vehicle, and adjust the combustion parameters of the target vehicle engine to the engine combustion parameters corresponding to the preset highway road condition.

[0068] Optionally, when calculating that the current road condition coefficient of the target vehicle is less than 0.28, it is determined as the urban working condition. If the coefficient = 0.47, it is determined as the suburban working condition. If the coefficient > 0.85, it is the highway working condition.

[0069] In one embodiment, the vehicle ECU determines the responsiveness (air-fuel ratio limit), the required value of the output power (external characteristic limit), and the throttle response characteristic (driving characteristic adaptability limit) of the target vehicle engine corresponding to the urban road condition, the suburban road condition, and the highway road condition according to look-up table interpolation.

[0070] Optionally, for different operating conditions and different usage scenarios, it is necessary to prepare three maps of air-fuel ratio limit, driving characteristic limit, and external characteristic limit under the three working conditions in advance. The ECU performs look-up table interpolation after obtaining the input and makes adaptive adjustment of the engine combustion parameters.

[0071] In one embodiment, based on information such as the positioning and vehicle speed of operating vehicles collected by the vehicle networking platform, a determination coefficient is output through the big data self-learning module for the same vehicle model. It should be noted that the determination coefficient output by the big data self-learning module can be understood as, through big data analysis, the current road condition coefficient of the vehicles on this route and the combustion parameters of the engine corresponding to the three road conditions of urban, suburban, and highway. Based on the repeatability of the target vehicle's route, the average determination coefficient of all vehicles of the same vehicle model (for non-fixed routes) or the determination coefficient of the fixed-route self-learning of the target vehicle alone is used as the input to the ECU. The ECU performs table lookup and interpolation according to different determination coefficients to adjust the adaptability of the engine combustion parameters to meet the power responsiveness under different operating conditions.

[0072] Referring to Figure 2 , Figure 2 FIG. shows a schematic diagram of a vehicle engine power adaptive device provided by the present invention. As Figure 2 shown, the device includes:

[0073] A judgment module 201: It is used to judge whether the route where the target vehicle is currently located is a fixed operating route.

[0077] Determine the road condition where the target vehicle is located according to the working condition coefficient of the current route, and adaptively adjust the combustion parameters of the vehicle engine.

[0078] Further, in a possible implementation manner, the judgment module 201 is further used to determine the current route repeatability of the target vehicle according to the historical operating route of the target vehicle;

[0079] When the route repeatability of the target vehicle is greater than the set threshold, it is determined that the target vehicle is currently on a fixed route;

[0080] When the route repeatability of the target vehicle is less than the set threshold, it is determined that the target vehicle is currently on a non-fixed route.

[0081] Further, in a possible implementation, the adjustment module 203 is further configured to, when the operating condition coefficient of the current route of the target vehicle is less than or equal to the first operating condition coefficient, determine the current urban road condition of the target vehicle, and adjust the combustion parameters of the engine of the target vehicle to the engine combustion parameters corresponding to the preset urban road condition;

[0082] When the operating condition coefficient of the current route of the target vehicle is equal to the second operating condition coefficient, determine the current suburban road condition of the target vehicle, and adjust the combustion parameters of the engine of the target vehicle to the engine combustion parameters corresponding to the preset suburban road condition;

[0083] When the operating condition coefficient of the current route of the target vehicle is greater than the third operating condition coefficient, determine the current highway road condition of the target vehicle, and adjust the combustion parameters of the engine of the target vehicle to the engine combustion parameters corresponding to the preset highway road condition.

[0084] Further, in a possible implementation, the adjustment module 203 is further configured to, according to the vehicle ECU's look-up table interpolation, determine the responsiveness of the engine power of the target vehicle, the required value of the output power, and the throttle response characteristics corresponding to the urban road condition, suburban road condition, and highway road condition of the target vehicle.

[0086] Further, in a possible implementation, the calculation module 202 is further configured to calculate the average road condition coefficient between the urban road condition and the suburban road condition when the target vehicle is between the urban road condition and the suburban road condition;

[0087] According to the average road condition coefficient, calculate the engine combustion parameters corresponding to the urban road condition and the suburban road condition.
