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.

[0054] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0055] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] This embodiment provides a user fuel consumption evaluation method based on historical climate data. Figure 1 As shown, the method includes steps 101 to 105:

[0057] Step 101: construct a target operating condition for fuel consumption evaluation of a target vehicle in a target area; divide the area to be tested into n target areas in advance;

[0058] Among them, the target vehicle refers to the vehicle for fuel consumption evaluation, and the vehicle can be a vehicle of the model to be tested. The area to be tested refers to the area where the fuel consumption evaluation needs to be performed. The area to be tested is generally large in area. For example, the area to be tested can be a province or a national region. In this embodiment, the national region is used as the area to be tested for illustration. The area to be tested is pre-divided into multiple target areas in advance. For example, the area to be tested is divided into 34 target areas with reference to the provincial division.

[0059] The target operating condition refers to the operating condition used for fuel consumption evaluation. When constructing the target operating condition, the construction method of each target area is similar, and one of the target areas is used as an example for explanation. When constructing the target operating condition of the target area, the provincial capital city of the area can be used as a typical city for collection.

[0060] Specifically, the target operating condition for fuel consumption evaluation of the target vehicle in the target area is constructed, including the following steps:

[0061] Using a target vehicle to collect traffic conditions in a target area and driving data under the traffic conditions;

[0062] Based on the collected traffic conditions and the driving data corresponding to the traffic conditions, a target operating condition for fuel consumption evaluation is constructed.

[0063] Specifically, the same target vehicle is used to collect the road traffic conditions in the target area, including urban congestion conditions, urban peak hours, ring road commuting, ring road peak hours, and ring road expressways. At the same time, driving data under corresponding traffic conditions are collected, including vehicle speed, engine speed, accelerator pedal opening, vehicle acceleration, engine load, etc.

[0064] After collecting the above road conditions and driving data, the data is processed, and each short trip of all collected vehicle trajectories is extracted and classified. Then, segments are randomly selected from each category to form an alternative working condition. Finally, the characteristic values ​​of the alternative working conditions are calculated, and the group closest to the overall data characteristics is selected as the target working condition, thereby constructing the target working condition for fuel consumption evaluation in the target area. Figure 3 As shown in the VT curve of the target operating condition in Wuhan area, Figure 3 Hubei is taken as the target area, and Wuhan is taken as a typical city in the target area. Referring to the above steps, the target working conditions of all target areas in the area to be tested can be obtained.

[0065] Step 102: Based on different seasons, the target vehicle performs a road sliding resistance test in a target area to obtain a fuel consumption evaluation resistance of the target area;

[0066] It is not difficult to understand that a year is divided into four seasons. Referring to Appendix CC of GB / T 18352.6, a road sliding resistance test in four seasons is carried out using a target vehicle in a target area, and the curb weight in the standard is replaced by half-loaded mass. Finally, the arithmetic mean of the sliding results in the four seasons is taken as the user fuel consumption evaluation resistance in the area. Among them, GB / T 18352.6 uses the test mass (calculated value based on curb weight, optional parts mass and maximum loading mass). Since it cannot represent the actual use of users, this embodiment uses half-loaded mass instead.

[0067] With reference to the above steps, the fuel consumption evaluation resistance of the target vehicle in all target areas can be determined.

[0068] Step 103: for each target area, according to the target operating conditions, fuel consumption evaluation resistance and engine universal characteristic curves obtained in different temperature ranges of the target area, the initial fuel consumption of the target vehicle in the target area under different use conditions is determined;

[0069] Combination Figure 2 As shown in the figure, different ambient temperature / intake air temperature will affect the performance of the engine. The temperature difference between different regions is relatively large, and the climate difference between different seasons is also different (for example, the difference between winter and summer is also different). Therefore, when evaluating fuel consumption, it is also necessary to consider the impact of the engine's performance changes caused by temperature changes.

[0070] In this embodiment, the engine working environment temperature is divided into 6 temperature intervals, namely 0°C and below, 0°C to 16°C, 16°C to 26°C, 26°C to 36°C, 36°C to 46°C, and above 46°C. Then, the universal characteristics and external characteristics of the same engine in these 6 temperature intervals are measured.

[0071] In this embodiment, according to the target operating conditions of the target area, the fuel consumption evaluation resistance and the engine universal characteristic curve in different temperature ranges, simulation is performed using software such as Matalab or Cruise to obtain the initial fuel consumption of the target vehicle in the target area under different usage conditions.

[0072] In addition, the use conditions are defined in this embodiment in combination with actual conditions. Optionally, the use conditions include temperature ranges, air conditioning accessories, wiper accessories, lamp loads, and display screens. The temperature ranges refer to the divisions of engine tests. Air conditioning accessories, wiper accessories, lamp loads, and display screens are combined into different use conditions by turning on and off states. Different use conditions can be referred to the table below. It should be noted that the table below does not include the impact of lamp loads, and the impact of lamp loads on fuel consumption will be analyzed separately below.

[0073]

[0074] Table 1 Different use conditions

[0075] It should be noted that in the same target area, under different usage conditions, the initial fuel consumption is slightly different.

[0076] Step 104: performing weighted correction processing on the initial fuel consumption under different usage conditions according to the climate data of the preset historical time period of the target area to determine the target fuel consumption;

[0077] In this embodiment, the preset historical time period refers to a historical period before the fuel consumption evaluation, for example, the five years before the target area are used as the preset historical time period. Climate data refers to the weather of the target area, which may specifically include temperature, cloud cover, precipitation, etc. In this embodiment, the climate data of Wuhan from 2017 to 2022 are statistically analyzed to obtain Table 2.

[0078]

[0079]

[0080] Table 2. Climate data of Wuhan from 2017 to 2022 (unit: days)

[0081] In addition to affecting engine performance, temperature also determines whether air conditioning accessories are turned on (for example, turning on heating or cooling); rainy and snowy weather determines whether wiper accessories are turned on; rain, fog, and haze weather affect the turning on of lamps. It is not difficult to understand that turning on these accessories will increase fuel consumption. Therefore, this embodiment is based on climate data, by counting the number of historical days that meet each usage condition, calculating the proportion of historical days for each usage condition, and then performing weighted correction processing on the initial fuel consumption to obtain the target fuel consumption. The specific steps may include:

[0082] Performing a first weighted correction process on the initial fuel consumption under different use conditions according to the climate data of the preset historical time period of the target area to obtain the corrected fuel consumption of the target area;

[0083] According to the climate data of the preset historical time period of the target area, based on the lamp load condition, a second weighted correction process is performed on the corrected fuel consumption to obtain the target fuel consumption.

[0084] It should be noted that the weighted correction process is divided into two parts. The first part is to consider the air conditioning accessories, wiper accessories and the opening and closing of the display screen to perform the first weighted correction process; the second part is to consider the influence of the lamp load on the basis of the first weighted correction process, and finally obtain the target fuel consumption. Among them, the first weighted correction process means that for each use condition, according to the climate data of the preset historical time period of the target area, the historical days that meet the use condition are determined respectively;

[0085] According to the historical days of the use condition, the initial fuel consumption under the use condition is weightedly corrected to obtain the updated initial fuel consumption;

[0086] According to the updated initial fuel consumption under various usage conditions, the corrected fuel consumption in the target area is obtained.

[0087] After determining the number of historical days under each use condition, the corresponding historical days can be divided by the total number of days to obtain a weight value, and then the initial fuel consumption corresponding to each use condition can be multiplied by the corresponding weight to obtain the corresponding updated initial fuel consumption. The updated initial fuel consumption can be added together to obtain the corrected fuel consumption.

[0088] The details are shown in Table 3 and Table 4.

[0089]

[0090] Table 3

[0091]

[0092]

[0093] Table 4

[0094] After obtaining the corrected fuel consumption, it is necessary to perform a second weighted correction process on the corrected fuel consumption to obtain the target fuel consumption, which specifically includes the following steps:

[0095] Determine the difference in fuel consumption of the target vehicle before and after the lamp load is turned on in the target area;

[0096] Determine the first time data of the target vehicle's lamp load being turned on and off in rain, fog, or haze weather; and the second time data of the target vehicle's lamp load being turned on and off in non-rain, fog, or haze weather;

[0097] According to the climate data of the preset historical time period of the target area, the proportion of rain, fog and haze weather in the target area is determined;

[0098] The target fuel consumption is determined based on the proportion of rain, fog and haze weather, as well as the first-time data, second-time data and the fuel consumption difference.

[0099] Specifically, after turning on the lamp load, fuel consumption will increase. However, how much it will increase specifically needs to be analyzed. First, through simulation, it can be concluded that under the same target area and the same target working conditions, the difference in fuel consumption between fully open and fully closed lamp loads is approximately 0.28L / 100km. Taking the climate data of the preset historical time period of Wuhan as an example, it is statistically concluded that the total number of days with rain, fog, and haze in Wuhan in the past five years is 418 days, accounting for 19.1%. For weather without rain, fog, or haze, it is defined as follows: the lamp load is turned on from 4:00 to 6:00 and from 16:00 to 1:00 the next morning; the time period from 1:00 to 4:00 is defined as when the vehicle is not in use, and the lamp load is turned off at other times. Thus, the second time data of the lamp load being turned on and off in non-rain, fog, and haze weather is obtained, that is, the ratio of lamp opening and closing is: 42.86% on and 57.14% off.

[0100] At the same time, when it is rainy, foggy, or hazy, it is defined as follows. The time period from 22:00 to 4:00 is defined as the vehicle not being used. The lamp load is turned on from 4:00 to 10:00 and from 17:00 to 22:00, and the lamp load is turned off at other times. Thus, the first time data of the lamp load turning on and off in rainy, foggy, or hazy weather is obtained, that is, the lamp on-off ratio is: 61.11% on, 38.89% off.

[0101] After obtaining the above data, the target fuel consumption F in Wuhan area after correction based on lamp load can be calculated by the following formula: 目标 for:

[0102] F 目标 =(7.26×42.86%+6.98×57.14%)×80.9%+(7.26×33.3%+6.98×66.7%)×19.1%=7.11L / 100km

[0103] Step 105: Based on the sales data of the target vehicles in each target area, weighted processing is performed on the target fuel consumption of each target area to determine the comprehensive fuel consumption of the target vehicle in the area to be tested.

[0104] With reference to the aforementioned steps, the target fuel consumption of all target areas can be calculated. After obtaining the target fuel consumption, the target fuel consumption of each target area can be weighted based on the sales data. Among them, the sales data can be a sales planning ratio or an actual sales ratio. This embodiment is not limited to this. Based on the sales data, the fuel consumption weight of each target area can be determined; then, based on the target fuel consumption of each target area and the corresponding fuel consumption weight, the comprehensive fuel consumption of the target vehicle in the area to be tested is finally determined. For example, the comprehensive fuel consumption of the target vehicle in the area to be tested can be calculated in combination with the data in Table 5.

[0138] In summary, a vehicle provided by an embodiment of this specification constructs a target operating condition for fuel consumption evaluation of a target vehicle in a target area; based on different seasons, the target vehicle performs a road sliding resistance test in the target area to obtain the fuel consumption evaluation resistance of the target area; for each target area, the initial fuel consumption of the target vehicle in the target area under different use conditions is determined according to the target operating condition, fuel consumption evaluation resistance and engine universal characteristic curves obtained in different temperature ranges; based on the climate data of the preset historical time period of the target area, the initial fuel consumption under different use conditions is weighted and corrected to determine the target fuel consumption; based on the sales data of the target vehicle in each target area, the target fuel consumption of each target area is weighted and processed to determine the comprehensive fuel consumption of the target vehicle in the area to be tested. The present invention takes into account the impact of different regional differences and different weather conditions on fuel consumption. Since the user fuel consumption evaluation conditions in different areas are constructed, it will become extremely fast when performing fuel consumption evaluation and benchmarking analysis on multiple models. At the same time, since the user's usage conditions are defined and classified, and the load and starting performance are corrected, the resulting fuel consumption is closer to the user's actual usage and has more guiding and reference significance for the development of vehicle models.
