[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] In a first aspect, the embodiments of the present application provide a vehicle cruising range evaluation method.

[0042] In one embodiment, with reference to Figure 1 , Figure 1 is a schematic flowchart of an embodiment of the vehicle cruising range evaluation method of the present application. As Figure 1 shown, the vehicle cruising range evaluation method includes:

[0043] Step S10: For each state of battery charge, based on the first ratio corresponding to each temperature condition, the second ratio corresponding to each driving condition, and the first cruising range of the vehicle to be evaluated under different combinations of temperature conditions and driving conditions, obtain the second cruising range of the vehicle to be evaluated under each state of battery charge;

[0044] In this embodiment, for the sake of convenience of description, three states of battery charge are taken as examples, namely 50% battery charge, 80% battery charge, and 100% battery charge; the temperature conditions include normal temperature, low temperature, ultra-low temperature, and high temperature, and the driving conditions include urban areas, suburbs, highways, and mountain roads. Any temperature condition and any driving condition form a combination of temperature condition and driving condition.

[0045] Further, in one embodiment, the first ratio corresponding to each temperature condition and the second ratio corresponding to each driving condition are determined through the following steps:

[0046] Obtain the historical driving data of a target vehicle with the same attributes as the vehicle to be evaluated; determine the first ratio corresponding to each temperature condition and the second ratio corresponding to each driving condition according to the historical driving data.

[0047] In this embodiment, a vehicle in the same price range as the vehicle to be evaluated and / or belonging to the same type can be used as the target vehicle with the same attributes as the vehicle to be evaluated.

[0048] Through the historical driving data, the driving duration of the target vehicle under various temperature conditions can be determined. For example, the driving duration at normal temperature is t1, the driving duration at low temperature is t2, the driving duration at ultra-low temperature is t3, and the driving duration at high temperature is t4. Then:

[0049]

[0050] Through the historical driving data, the driving mileage of the target vehicle under various driving conditions can be determined. For example, the driving mileage in urban areas is s1, the driving mileage in suburbs is s2, the driving mileage on highways is s3, and the driving mileage on mountain roads is s4. Then:

[0051]

[0052] Further, in one embodiment, step S10 includes:

[0053] For a state of battery charge, multiply the first cruising range of the vehicle under a combination of temperature condition and driving condition by the first ratio corresponding to the temperature condition in the combination of temperature condition and driving condition and the second ratio corresponding to the driving condition in the combination of temperature condition and driving condition to obtain the product corresponding to the combination of temperature condition and driving condition;

[0054] And so on, the products corresponding to all combinations of temperature conditions and driving conditions are obtained;

[0055] Accumulate the products corresponding to all combinations of temperature conditions and driving conditions to obtain the second cruising range of the vehicle to be evaluated under a certain state of charge;

[0056] And so on, the second cruising range of the vehicle to be evaluated under each state of charge is obtained.

[0057] In this embodiment, the first cruising range of the vehicle under a certain combination of temperature condition and driving condition (such as normal temperature - urban area) at 50% state of charge is multiplied by the first ratio corresponding to normal temperature and the second ratio corresponding to urban area to obtain the product corresponding to the combination of temperature condition and driving condition of normal temperature - urban area; and so on, the products corresponding to all combinations of temperature conditions and driving conditions can be obtained; then, accumulate the products corresponding to all combinations of temperature conditions and driving conditions to obtain the second cruising range of the vehicle to be evaluated under a certain state of charge (50% state of charge).

[0058] Similarly, the first cruising range of the vehicle under a certain combination of temperature condition and driving condition (such as normal temperature - urban area) at 80% state of charge is multiplied by the first ratio corresponding to normal temperature and the second ratio corresponding to urban area to obtain the product corresponding to the combination of temperature condition and driving condition of normal temperature - urban area; and so on, the products corresponding to all combinations of temperature conditions and driving conditions can be obtained; then, accumulate the products corresponding to all combinations of temperature conditions and driving conditions to obtain the second cruising range of the vehicle to be evaluated under a certain state of charge (80% state of charge).

[0059] And so on, the second cruising range of the vehicle to be evaluated under each state of charge can be obtained.

[0060] Step S20: According to the conversion coefficient of each state of charge relative to the fully charged state, perform conversion processing on the second cruising range of the vehicle to be evaluated under each state of charge to obtain the third cruising range of the vehicle to be evaluated under each state of charge;

[0061] Furthermore, in one embodiment, the conversion coefficient of each state of charge relative to the fully charged state is determined through the following steps:

[0062] Based on the same bench test conditions, measure the cruising range test values of the vehicle under different states of charge, and the different states of charge include the fully charged state and non - fully charged states;

[0063] Take the ratio of the cruising range test value in the fully charged state to the cruising range test value in a certain state of charge as the conversion coefficient of a certain state of charge relative to the fully charged state;

[0064] And so on, the conversion coefficients of each power state relative to the full charge state are obtained.

[0065] In this embodiment, taking different power states including 50%, 80%, and 100% as examples, based on the same bench test conditions, the driving range test values of the vehicle at 50%, 80%, and 100% power states can be measured. The ratio of the driving range test value at 50% power state to the driving range test value at 100% power state is used as the conversion coefficient of 50% power state relative to the full charge state; similarly, the ratio of the driving range test value at 80% power state to the driving range test value at 100% power state is used as the conversion coefficient of 80% power state relative to the full charge state.

[0066] Further, in one embodiment, step S20 includes:

[0067] Multiply the conversion coefficient of each power state relative to the full charge state by the second driving range of the vehicle to be evaluated at each power state to obtain the third driving range of the vehicle to be evaluated at each power state.

[0068] In this embodiment, the ideal driving range at 100% power is usually given by the automobile manufacturer. In actual use, due to the self-discharge factor, the driving range at 100% power is often more than twice the driving range corresponding to 50% power. This is caused by the power loss during non-driving time. Therefore, it is necessary to calculate the driving range converted to 100% power at different power states, that is, multiply the conversion coefficient of each power state relative to the full charge state by the second driving range of the vehicle to be evaluated at each power state to obtain the third driving range of the vehicle to be evaluated at each power state.

[0069] Step S30: Synthesize the third driving ranges of the vehicle to be evaluated at multiple power states to obtain the driving range of the vehicle to be evaluated at the full charge state.

[0070] In this embodiment, in order to obtain a more accurate driving range of the vehicle to be evaluated at the full charge state, the average value of the third driving ranges of the vehicle to be evaluated at multiple power states can be calculated, and the average value is used as the driving range of the vehicle to be evaluated at the full charge state.

[0071] Further, in one embodiment, the vehicle driving range evaluation method further includes:

[0072] Obtain the historical charging data of the target vehicle with the same attributes as the vehicle to be evaluated; determine the number of times of charging to each power state according to the historical charging data; determine the weighting coefficient corresponding to each power state based on the number of times of charging to each power state.

[0073] In this embodiment, assuming that the number of times the target vehicle is charged to 50% state of charge is C1, the number of times the target vehicle is charged to 80% state of charge is C2, and the number of times the target vehicle is charged to 100% state of charge is C3, then:

[0074]

[0075] Further, in one embodiment, step S30 includes:

[0076] Weighted sum the third driving ranges of the vehicle to be evaluated under multiple states of charge to obtain the driving range of the vehicle to be evaluated in a fully charged state.

[0077] In this embodiment, according to the weighted coefficients corresponding to each state of charge determined above, weighted sum the third driving ranges of the vehicle to be evaluated under multiple states of charge, and use the weighted sum result as the driving range of the vehicle to be evaluated in a fully charged state.

[0078] In the embodiments of the present application, for each state of charge, according to the first ratio corresponding to each temperature condition, the second ratio corresponding to each driving condition, and the first driving range of the vehicle to be evaluated under different combinations of temperature conditions and driving conditions, obtain the second driving range of the vehicle to be evaluated under each state of charge; perform conversion processing on the second driving range of the vehicle to be evaluated under each state of charge according to the conversion coefficient of each state of charge relative to the fully charged state to obtain the third driving range of the vehicle to be evaluated under each state of charge; comprehensively consider the third driving ranges of the vehicle to be evaluated under multiple states of charge to obtain the driving range of the vehicle to be evaluated in a fully charged state. Through the embodiments of the present application, by comprehensively considering the influence of the state of charge, temperature conditions, and driving conditions on the driving range, the accuracy of the finally determined driving range of the vehicle in a fully charged state is improved.
