Description

Technical Field

[0001] The present invention relates to the field of electric vehicle control technology, and in particular to a vehicle cruising range prediction method, device, equipment and readable storage medium. Background Art

[0002] In recent years, the new energy vehicle industry has experienced rapid growth, demonstrating significant value in environmental protection and sustainable energy utilization. Driving range is a key consideration for new energy vehicle users, as these vehicles often have limitations in charging speed and convenience. Accurately estimating driving range can help users plan their trips more effectively and enhance their driving experience.

[0003] Currently, most vehicle range estimation methods first estimate the remaining available battery charge based on the vehicle's remaining SOC and battery status. The average battery consumption is then calculated based on the vehicle's previous power consumption over a certain distance. Finally, the remaining range is calculated based on the available power and average power consumption. This calculation logic provides a relatively accurate range estimate for most driving conditions with minimal altitude fluctuations.

[0004] However, when a vehicle is continuously traveling uphill or downhill, the vehicle's energy consumption increases significantly due to the change in altitude. The vehicle must overcome its own gravitational potential energy when traveling uphill, while it decreases significantly when traveling downhill. This change in energy consumption can interfere with the calculation of the driving range, leading users to misjudge the vehicle's range. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a vehicle range prediction method, device, equipment and readable storage medium, aiming to solve at least one of the above technical problems.

[0006] The technical solution of the present invention to solve the above technical problems is as follows:

[0007] In a first aspect, the present application provides a method for predicting vehicle range, which adopts the following technical solutions:

[0008] A vehicle cruising range prediction method, comprising:

[0010] Determining the remaining available power of the battery of the target vehicle based on the battery information;

[0011] determining, based on the navigation information, energy change information of the target vehicle on the navigation path, the energy change information representing a net potential energy change of the target vehicle caused by an elevation difference on the navigation path;

[0012] Determining equivalent available energy based on the remaining available power of the battery of the target vehicle and the energy change information, wherein the equivalent available energy represents the available energy of the battery after correcting for the influence of terrain energy conditions;

[0016] On the basis of the above technical solution, the present invention can also be improved as follows.

[0017] Further, determining the energy change information of the target vehicle on the navigation path based on the navigation information includes:

[0018] Determining the remaining navigation range of the target vehicle at the current moment based on the current position of the target vehicle at the current moment, the destination position, and the elevation distribution information of the navigation path;

[0019] Determining whether the target vehicle's current remaining navigation mileage is greater than a historical remaining navigation mileage, where the historical remaining navigation mileage represents the target vehicle's previous remaining navigation mileage at the current moment;

[0020] If the remaining navigation range of the target vehicle at the current moment is greater than the remaining historical navigation range, determining energy change information of the target vehicle along the navigation path based on a first altitude of the current location, a second altitude of the destination location, and a preset energy change formula, wherein the elevation distribution information of the navigation path includes the first altitude of the current location and the second altitude of the destination location, and the preset energy change formula represents a relationship between energy change and altitude;

[0021] If the remaining navigation mileage of the target vehicle at the current moment is not greater than the remaining historical navigation mileage, energy change information of the target vehicle on the navigation path is determined based on the first altitude of the current position, the third altitude of the waypoint position, and a preset energy change formula, the waypoint position representing the waypoint position of the target vehicle on the navigation path at which the historical navigation remaining mileage is located from the current position, and the elevation distribution information of the navigation path also includes the third altitude of the waypoint position.

[0022] The beneficial effects of adopting the above-mentioned further scheme are: determining the remaining navigation mileage based on the current position of the target vehicle at the current moment, the destination position and the elevation distribution information of the navigation path, combining the historical navigation remaining mileage judgment, using different altitudes and a preset energy change formula to determine the energy change information on the navigation path, which can accurately take into account the net potential energy change caused by the elevation difference from the current position to the destination of the target vehicle, and then subsequently determine the equivalent available energy based on the energy change information, and ultimately more accurately determine the remaining cruising range of the target vehicle, eliminating the interference of the vehicle's driving altitude change on the cruising range estimation, and improving the accuracy of the cruising range estimation.

[0023] Furthermore, determining the equivalent available energy based on the remaining available power of the battery of the target vehicle and the energy change information includes:

[0024] Equivalent available energy is determined based on a difference between the remaining available power of the battery of the target vehicle and the energy change information.

[0025] The beneficial effect of adopting the above further solution is: using the remaining available battery power minus the energy change information to obtain the equivalent available energy, which can eliminate the interference of vehicle altitude changes on the range estimation and improve the accuracy of the range estimation.

[0026] Furthermore, determining the equivalent power consumption of the target vehicle based on the historical driving energy consumption information includes:

[0027] Calculating the energy change of the target vehicle within a preset distance before the current position based on the historical altitude, the first altitude of the current position, and a preset energy change formula;

[0028] The equivalent power consumption of the target vehicle is determined based on the historical power consumption, the energy change of the target vehicle within a preset distance before the current position, and the calibratable parameter.

[0029] The beneficial effect of adopting the above-mentioned further scheme is: combining the historical altitude, the first altitude of the current position and the preset energy change formula to calculate the energy change of the vehicle within a preset distance before the current position, and further combining the historical power consumption and the calibratable parameters to determine the equivalent power consumption. In the process of calculating the power consumption, the power consumption change caused by the change of gravitational potential energy can be eliminated, and the interference of the change of the vehicle's driving altitude on the estimation of the cruising range can be eliminated, thereby improving the estimation accuracy of the cruising range.

[0056] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0058] An embodiment of the present application provides a vehicle range prediction method, which can be executed by an electronic device, which may be a controller, but is not limited thereto.

[0059] like Figure 1 As shown, a vehicle range prediction method mainly includes:

[0060] S1, obtaining battery information, navigation information, and historical driving energy consumption information of a target vehicle at a current moment, wherein the battery information includes a current battery temperature, a current battery state of humidity (SOH), and a current battery remaining state of charge (SOC); the navigation information includes a current location of the target vehicle at a current moment, a destination location, and elevation distribution information of a navigation path; the historical driving energy consumption information represents driving energy consumption data of the target vehicle within a preset distance before the current location, and the historical driving energy consumption information includes historical altitudes, historical power consumption, and calibratable parameters;

[0061] In an embodiment of the present application, the lowest temperature of the target vehicle's single cell battery measured by the battery temperature sensor is the current battery temperature; the current battery SOH is the current battery health status, and the current battery SOH is calculated by the factory rated capacity, discharge time and constant current of the battery; the current battery remaining SOC is the current remaining battery power, and the current battery remaining SOC can be calculated by integrating the battery's charge and discharge current and combining it with the initial SOC.

[0062] Navigation information is primarily obtained through the target vehicle's navigation system. The current and destination locations can be accurately determined using the Global Positioning System (GPS) or the Beidou satellite navigation system, which provide real-time location information such as the vehicle's latitude and longitude coordinates. Elevation information for the navigation path can be obtained from high-precision map data.

[0063] The historical driving energy consumption information needs to be collected and organized by the energy consumption monitoring system of the target vehicle. The energy consumption monitoring system records the driving energy consumption data of the target vehicle within a preset distance before the current position. The historical altitude data can be obtained by the on-board height sensor. The historical power consumption can be obtained by statistically analyzing the vehicle's electricity meter readings. The calibratable parameters can be set and adjusted in the vehicle's control system according to actual needs. The calibratable parameters represent the time window length of the historical data, and the calibratable parameters are positively correlated with the stability of the driving range display and negatively correlated with the real-time performance. The reference value is 50 kilometers.

[0064] S2, determining the remaining available power of the battery of the target vehicle based on the battery information;

[0065] In an embodiment of the present application, the remaining available battery capacity of the target vehicle is calculated based on the battery characteristic curve, combined with the current battery temperature, the current battery SOH, and the current battery remaining SOC. In this process, the battery temperature affects the chemical reaction rate within it, thereby affecting the battery's available capacity; the battery's SOH reflects the degree of battery aging. The higher the degree of aging, the lower the actual available capacity of the battery; and the battery's remaining SOC directly represents the battery's current state of charge. By comprehensively considering these factors, the remaining available battery capacity can be estimated more accurately. The remaining available battery capacity is prior art and is not described in detail in this patent.

[0066] S3, determining energy change information of the target vehicle on the navigation path based on the navigation information, wherein the energy change information represents a net potential energy change of the target vehicle caused by the elevation difference on the navigation path;

[0067] In the embodiment of the present application, specifically, determining the energy change information of the target vehicle on the navigation path based on the navigation information includes:

[0068] Determining the remaining navigation range of the target vehicle at the current moment based on the current position of the target vehicle at the current moment, the destination position, and the elevation distribution information of the navigation path;

[0069] Determining whether the target vehicle's current remaining navigation mileage is greater than a historical remaining navigation mileage, where the historical remaining navigation mileage represents the target vehicle's previous remaining navigation mileage at the current moment;

[0070] If the remaining navigation range of the target vehicle at the current moment is greater than the remaining historical navigation range, determining energy change information of the target vehicle along the navigation path based on a first altitude of the current location, a second altitude of the destination location, and a preset energy change formula, wherein the elevation distribution information of the navigation path includes the first altitude of the current location and the second altitude of the destination location, and the preset energy change formula represents a relationship between energy change and altitude;

[0071] If the target vehicle's remaining navigation mileage at the current moment is not greater than the target vehicle's remaining historical navigation mileage, the target vehicle's energy change information on the navigation path is determined based on the first altitude of the current position, the third altitude of the waypoint position, and a preset energy change formula. The waypoint position represents the target vehicle's position on the navigation path at a distance from the current position to the historical navigation remaining mileage. The elevation distribution information of the navigation path also includes the third altitude of the waypoint position.

[0072] In this embodiment of the present application, if the remaining mileage calculated by the navigation is greater than the remaining mileage of the historical navigation, the first altitude data h of the current location and the second altitude h2 of the destination are obtained according to the location information, and the altitude difference △h2 between the current location and the destination is calculated according to the formula;

[0073] Where, △h2=h2-h;

[0074] Where h2 is the altitude of the destination, and h is the altitude of the current location.

[0075] If the remaining mileage calculated by the navigation is not greater than the remaining mileage in the historical navigation, the third altitude h3 of the waypoint in the driving route that is the distance from the current position to the historical remaining mileage is obtained based on the route information, and the altitude data h of the current position is obtained. The altitude difference △h3 between the current position and the waypoint is calculated according to the formula;

[0076] Where, △h3=h3-h;

[0077] Where h3 is the altitude of the waypoint, and h is the altitude of the current location.

[0078] In the embodiment of the present application, the preset energy change formula is:

[0079]

[0080] Among them, △W is the energy change, m is the vehicle mass, g is the acceleration of gravity, △h is the elevation difference, when the target vehicle's remaining navigation mileage at the current moment is greater than the historical navigation remaining mileage, △h = △h2, when the target vehicle's remaining navigation mileage at the current moment is not greater than the historical navigation remaining mileage, △h = △h3, η is the vehicle's comprehensive driving efficiency, which is calibrated according to vehicle performance.

[0081] S4, determining equivalent available energy based on the remaining available power of the battery of the target vehicle and the energy change information, where the equivalent available energy represents the available energy of the battery after correcting for the influence of terrain energy conditions;

[0082] In the embodiment of the present application, specifically, determining the equivalent available energy based on the remaining available power of the battery of the target vehicle and the energy change information includes:

[0083] The equivalent available energy is determined based on the difference between the target vehicle's remaining battery charge and the energy change information. The effect of terrain energy on the battery's available energy is corrected so that the calculated equivalent available energy more accurately reflects the vehicle's actual available energy during driving.

[0084] The calculation formula for equivalent available energy is:

[0085] W′ =W-△W

[0086] Among them, W ′ is the equivalent available energy, W is the remaining available power of the target vehicle’s battery, and ΔW is the energy change information of the target vehicle.

[0087] S5, determining the equivalent power consumption of the target vehicle based on the historical driving energy consumption information, where the equivalent power consumption represents energy consumption per unit mileage;

[0088] In the embodiment of the present application, specifically, determining the equivalent power consumption of the target vehicle based on the historical driving energy consumption information includes:

[0089] Calculating the energy change of the target vehicle within a preset distance before the current position based on the historical altitude, the first altitude of the current position, and a preset energy change formula;

[0090] The equivalent power consumption of the target vehicle is determined based on the historical power consumption, the energy change of the target vehicle within a preset distance before the current position, and the calibratable parameter.

[0091] For example, the actual electric energy consumed by the vehicle within a preset distance can be calculated after excluding the energy change caused by elevation change, and then divided by the preset distance to obtain the equivalent power consumption per unit mileage.

[0092] In the embodiment of the present application, first, the driving data parameters of the vehicle within the previous N kilometers are collected, including the vehicle altitude h1 and power consumption W1 before N kilometers. N is a calibrable parameter. The larger the N value, the better the stability of the driving range display but the worse the real-time performance. The reference value of N is 50km.

[0093] Then, the target vehicle’s altitude change △h1 within the first N kilometers is calculated, and the energy change △W1 caused by the altitude change within the first N kilometers is calculated based on △h1;

[0094] Where, △h1=h1-h;

[0095]

[0096] Among them, △h1 is the energy change within a preset distance before the current position, h1 is the historical altitude, h is the first altitude of the current position, △W1 is the energy change within a preset distance before the current position, m is the vehicle mass, g is the acceleration of gravity, and η is the vehicle's comprehensive driving efficiency, which is calibrated according to vehicle performance.

[0097] Finally, the equivalent power consumption A per 100 kilometers of the vehicle is calculated based on the vehicle power consumption W1 within N kilometers and the energy change △W1 caused by the altitude change within the first N kilometers of the vehicle.

[0098] in,

[0099]

[0100] Among them, A is the equivalent power consumption of the target vehicle, △W1 is the energy change within the preset distance before the current position, and W1 is the historical power consumption.

[0101] S6: Determine the remaining cruising range of the target vehicle based on the equivalent available energy and the equivalent power consumption of the target vehicle.

[0102] In the embodiment of the present application, the calculation formula for the remaining cruising range is:

[0103]

[0104] Among them, S is the remaining range of the target vehicle, W ′ is the equivalent available energy of the target vehicle, and A is the equivalent power consumption of the target vehicle.

[0105] This method eliminates the change in power consumption caused by changes in gravitational potential energy during the calculation of power consumption, obtains the destination altitude information through navigation information, and introduces the energy generated or consumed by the change in gravitational potential energy when the vehicle reaches the destination from the current position into the final range calculation. This eliminates the interference of changes in the vehicle's driving altitude on the range estimation and improves the accuracy of the range estimation.
