These forecasts are tailored to the specific vehicle, user, and travel route. Because a vehicle's actual energy consumption depends not only on the vehicle's baseline energy consumption but also on road conditions, the energy consumption of the same vehicle model can vary significantly when used in different regions, such as different cities. Existing technologies lack a method for evaluating the overall energy consumption of a specific vehicle model within a specific region. Summary of the Invention

[0014] Furthermore, the ambient temperature range and the vehicle speed range are divided into a plurality of continuous intervals, and a method for obtaining a plurality of ambient temperature intervals and vehicle speed intervals includes:

[0015] Taking the lower limit of the ambient temperature range as the starting point, divide the ambient temperature range into several consecutive ambient temperature intervals according to the interval m. During the division process, the span of the last ambient temperature interval including the upper limit of the ambient temperature range is allowed to be less than m;

[0016] Taking the lower limit of the speed range as the starting point, the speed range is divided into several continuous speed intervals according to the interval n. During the division process, the span of the last ambient temperature interval in the speed range is allowed to be less than n.

[0017] Furthermore, based on the driving data of all vehicles of the target vehicle model, the method for obtaining the average energy consumption level and the proportion of power consumption of all vehicles in each ambient temperature range and speed range includes:

[0018] Obtaining, based on the driving data of all vehicles of the target vehicle model, a first total power consumption of all vehicles in each ambient temperature range and vehicle speed range, and a second total power consumption of all vehicles in all ambient temperature ranges and vehicle speed ranges;

[0019] Based on the driving data of all vehicles of the target model, the total mileage of all vehicles in each ambient temperature range and speed range is obtained;

[0054] Figure 2This is a structural diagram of the actual energy consumption evaluation system of the vehicle model of the present invention in a certain city. DETAILED DESCRIPTION

[0055] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0056] Example 1

[0057] Figure 1 The present invention shows a method for evaluating the actual energy consumption of a vehicle in a certain city. Figure 1 As shown, the actual energy consumption evaluation method of the vehicle model in a certain city includes the following steps S10-S40.

[0058] Step S10: Acquire driving data of all vehicles of the target model within a set time interval in the target city, wherein the driving data includes: data on changes in ambient temperature over time, data on changes in battery charge over time, data on changes in vehicle speed over time, and data on changes in mileage over time during each driving process of the vehicle.

[0059] The target vehicle type is a pure electric vehicle. Generally, based on the user's cloud-based big data, the driving data of all vehicles of the target vehicle type can be obtained. The set time interval is generally in months, and the driving data within one month, two months, etc. can be collected for analysis.

[0060] Step S20: Determine the ambient temperature range and speed range for the target vehicle model, and divide the ambient temperature range and speed range into a number of continuous intervals, respectively, to obtain multiple ambient temperature intervals and speed intervals. Divide the actual road scene into intervals based on speed and ambient temperature for subsequent analysis.

[0061] In certain embodiments, the method for determining the ambient temperature range and vehicle speed range of a target vehicle model includes the following steps a1 and a2.

[0062] Step a1: Obtain the maximum value of the ambient temperature T in the driving data of all vehicles of the target model max and the minimum value T min , and the maximum vehicle speed V max and minimum value V min ;

[0063] Step a2: Determine the target vehicle's ambient temperature range (T min , T max ), and the speed range is (V min , V max ).

[0064] For example: the maximum value of the ambient temperature T max For 30℃ and minimum T min At -15℃, the maximum speed V max 120km / h and minimum V min If the vehicle speed is 10km / h, the vehicle driving environment temperature range is (-15, 30), and the vehicle speed range is (10, 120).

[0065] In some embodiments, the ambient temperature range and the vehicle speed range are divided into a plurality of continuous intervals, and a method for obtaining a plurality of ambient temperature intervals and vehicle speed intervals includes the following steps b1 and b2.

[0066] Step b1: Taking the lower limit of the ambient temperature range as a starting point, divide the ambient temperature range into a number of consecutive ambient temperature intervals at intervals m, wherein the span of the last ambient temperature interval including the upper limit of the ambient temperature range is allowed to be less than m during the division process;

[0067] Step b2: starting from the lower limit of the vehicle speed range, the vehicle speed range is divided into a number of continuous vehicle speed intervals according to the interval n. During the division process, the span of the last ambient temperature interval in the vehicle speed range is allowed to be less than n.

[0068] Taking m=5℃ and n=10km / h as an example, combined with the above ranges, the vehicle speed range is 10~20km / h, 20~30km / h, 30~40km / h...110-120km / h, and the temperature range is -15~-5℃, -5~0℃, 0~5℃...25-30℃.

[0069] Step S30: Based on the driving data of all vehicles of the target vehicle model, the average energy consumption level and the proportion of power consumption of all vehicles in each ambient temperature range and vehicle speed range are obtained.

[0071] Step c1: Based on the driving data of all vehicles of the target vehicle model, obtain the first total power consumption of all vehicles in each ambient temperature range and vehicle speed range, and the second total power consumption of all vehicles in all ambient temperature ranges and vehicle speed ranges.

[0072] In some embodiments, a method for obtaining a first total power consumption of all vehicles within a certain ambient temperature range and vehicle speed range based on driving data of all vehicles of a target vehicle model includes the following steps d1 and d2.

[0073] Step d1: Analyze the power consumption of one or more driving segments within the ambient temperature range and vehicle speed range during each driving process of each vehicle.

[0074] Step d2: Sum the power consumption of all vehicles during all driving processes, corresponding to one or more driving segments within the ambient temperature and speed ranges, to obtain the first total power consumption for all vehicles within each ambient temperature and speed range. Combining the aforementioned range divisions, the first total power consumption for all vehicles within each ambient temperature and speed range is obtained as shown in Table 1 below.

[0085] Step c3: Divide the first total power consumption of all vehicles within the ambient temperature range and speed range by the corresponding total mileage to obtain the average energy consumption level for all vehicles within that ambient temperature range and speed range. Combining Tables 1 and 2 above, Table 3: Average Energy Consumption Levels for All Vehicles in Different Ambient Temperature and Speed ​​Ranges.
