[0001] The present disclosure relates to the field of vehicle control, and particularly to a vehicle control method, a vehicle, and a cloud server. Background Art

[0002] With the rapid development of the vehicle technology field, vehicles have become important means of transportation in people's daily lives. During the driving process of a hybrid vehicle, when the remaining power of the vehicle is relatively low, the vehicle mainly relies on the engine to drive.

[0003] In the above scenario, when the vehicle enters a climbing working condition, due to the influence of the slope, the engine load increases and the engine water temperature rises, resulting in a decrease in the overall vehicle power performance and a reduction in driving safety, posing a potential safety hazard. Summary of the Invention

[0004] In view of this, the purpose of the present disclosure is to provide a vehicle control method, a vehicle, and a cloud server to solve the problem that when the current remaining power of the vehicle is relatively low and it enters a climbing working condition, due to the influence of the slope, the engine load increases, the engine water temperature rises, resulting in a decrease in the overall vehicle power performance and a reduction in driving safety, posing a potential safety hazard.

[0007] Determine that the vehicle operation information and the current environment information meet the preset activation conditions, and control the vehicle engine to charge the vehicle battery until the battery power is greater than or equal to the target power.

[0008] Based on the same inventive concept, the second aspect of the present disclosure proposes a vehicle control method, which is applied to the cloud. The method includes:

[0009] Obtain the current position information of the vehicle, and determine whether the vehicle is within the power-preserving climbing geographical fence according to the current position information, where the power-preserving climbing geographical fence is determined based on the position information of multiple historical target vehicles with overheating failures, and the vehicle operation information and the ambient temperature and road surface slope of the historical target vehicle at the moment of overheating failure meet the preset conditions;

[0010] In response to determining that the vehicle is within the power conservation climbing geographic fence, determine the target power corresponding to the power conservation climbing geographic fence, and send the target power and location prompt information to the vehicle;

[0011] Wherein, the location prompt information is used to prompt that the vehicle is within the power conservation climbing geographic fence.

[0012] Based on the same inventive concept, a third aspect of the present disclosure proposes a vehicle control device, which is arranged at the vehicle end, and the device includes:

[0013] A data acquisition module, configured to, in response to receiving the location prompt information and the target power sent by the cloud, acquire vehicle operation information and current environment information, wherein the location prompt information is information for prompting that the vehicle is within the power conservation climbing geographic fence, and the target power represents the power that the vehicle battery needs to reach when driving within the power conservation climbing geographic fence;

[0014] A control module, configured to determine that the vehicle operation information and the current environment information meet a preset activation condition, and control the vehicle engine to charge the vehicle battery until the battery power is greater than or equal to the target power.

[0015] Based on the same inventive concept, a fourth aspect of the present disclosure proposes a vehicle control device, which is arranged at the cloud end, and the device includes:

[0016] A judgment module, configured to acquire the current location information of the vehicle, and judge whether the vehicle is within the power conservation climbing geographic fence according to the current location information, wherein the power conservation climbing geographic fence is determined based on the location information of multiple historical target vehicles with overheating failures, and the vehicle operation information and the ambient temperature and road surface gradient of the historical target vehicles at the moment of overheating failure meet preset conditions;

[0017] A data sending module, configured to, in response to determining that the vehicle is within the power conservation climbing geographic fence, determine the target power corresponding to the power conservation climbing geographic fence, and send the target power and location prompt information to the vehicle;

[0018] Wherein, the location prompt information is used to prompt that the vehicle is within the power conservation climbing geographic fence.

[0019] Based on the same inventive concept, a fifth aspect of the present disclosure proposes an electronic device, including a memory, a processor, and a computer program stored on the memory and executable by the processor, and the processor realizes the vehicle control method as described above when executing the computer program.

[0020] Based on the same inventive concept, a sixth aspect of the present disclosure provides a non-transitory computer-readable storage medium storing computer instructions for causing a computer to execute the vehicle control method as described above.

[0023] As can be seen from the above, the present disclosure provides a vehicle control method, a vehicle and a cloud server. When receiving the position prompt information and the target power sent from the cloud, it indicates that the vehicle is within the power-preserving climbing geographic fence. To ensure the power performance of the vehicle during subsequent climbing, within the power-preserving climbing geographic fence, the vehicle should increase the power of its own battery. When it is determined that the vehicle operation information and the current environment information meet the preset activation conditions, the vehicle engine is controlled to charge the vehicle battery. Charging the battery after meeting the activation conditions can avoid charging when the current driving state of the vehicle or the environment where the vehicle is located is not suitable, which may pose a threat to the stable and safe driving of the vehicle. At the same time, by charging the battery, it can be avoided that the battery power is too low during subsequent climbing, resulting in the phenomenon of relying only on the engine to drive the vehicle to climb. The electric drive system is used to assist in driving, reducing the risk of engine overheating and improving the power performance of the whole vehicle. The vehicle battery is charged until the battery power is greater than or equal to the target power, and the target power represents the power required by the vehicle battery when driving within the power-preserving climbing geographic fence, avoiding excessive engine energy consumption caused by continuously charging the battery.

The VIN code is the unique identity identification information of the vehicle, which can identify information such as the vehicle manufacturer, production year, vehicle model, body type and code, engine code, and assembly location.

[0036] With the rapid development of the vehicle technology field, vehicles have become important means of transportation in people's daily lives. During the driving process of a hybrid vehicle, when the remaining battery power of the vehicle is relatively low, the vehicle mainly relies on the engine to drive.

[0037] In the above scenario, when the vehicle enters a climbing working condition, due to the influence of the slope, the engine load increases and the engine water temperature rises, resulting in a decrease in the overall vehicle power performance and a reduction in driving safety, presenting a potential safety hazard.

[0038] Based on the above description, this embodiment proposes a vehicle control method, as Figure 1 shown, which is applied to the vehicle end, and the method includes:

[0039] Step 101, in response to receiving the position prompt information and the target power sent by the cloud, obtain the vehicle operation information and the current environment information, where the position prompt information is information indicating that the vehicle is within the power-preserving climbing geographical fence, and the target power represents the power that the vehicle battery needs to reach when driving within the power-preserving climbing geographical fence.

[0040] Specifically, during the driving process of the vehicle, if the position prompt information and the target power sent by the cloud are received, it indicates that the vehicle has entered the power-preserving climbing geographical fence at this time.

[0041] The content form of the position prompt information includes at least one of the following: voice, text, picture, video, and rich text. The prompting method of the position prompt information includes at least one of the following: voice broadcast, HUD display, instrument display, center control screen display, window display, and in-vehicle device linkage, etc. Among them, HUD display is a head-up display. Exemplarily, if the prompting method of the position prompt information is HUD display, the position prompt information will be projected in front of the user's eyes.

[0042] Exemplarily, if the content form of the position prompt information is text and the prompting method is center control screen display, the position prompt information such as "You have entered the power-preserving climbing area" will be displayed on the center control screen.

[0043] Obtain the vehicle operation information and the current environment information. The vehicle operation information represents the relevant parameter information of the current operation of the vehicle, specifically including at least one of the following: vehicle driving mode, engine outlet water temperature, vehicle battery power, vehicle speed, remaining total available driving mileage of the vehicle, and available driving mileage corresponding to the current vehicle power, etc.

[0044] Among them, the remaining total available driving mileage of the vehicle represents the sum of the remaining available driving mileage corresponding to the vehicle engine and the remaining available driving mileage corresponding to the vehicle battery, and the available driving mileage corresponding to the current vehicle power represents the remaining available driving mileage when the vehicle is driven only by the vehicle battery.

[0045] The current environmental information represents the environmental information corresponding to the current driving area of the vehicle, specifically including at least one of the following: environmental temperature, environmental humidity, etc.

[0046] Step 102, determine that the vehicle operation information and the current environmental information meet the preset activation conditions, and control the vehicle engine to charge the vehicle battery until the battery power is greater than or equal to the target power.

[0047] Specifically in implementation, after obtaining the vehicle operation information and the current environmental information, it is judged whether the vehicle operation information and the current environmental information meet the preset activation conditions. Specifically, the activation conditions can be;

[0048] The vehicle driving mode is a non-pure electric driving mode, the environmental temperature is greater than or equal to the preset temperature threshold, the engine outlet water temperature is less than the preset water temperature threshold, the vehicle battery power is less than the target power corresponding to the power preservation and climbing geographic fence, the vehicle speed is greater than or equal to the preset vehicle speed threshold, and the remaining total available driving mileage of the vehicle is greater than or equal to the first preset driving mileage.

[0049] For a vehicle with a driving mode in pure electric mode and the vehicle's navigation function is turned on, the activation conditions can also be:

[0050] The available driving mileage corresponding to the current vehicle power is less than the second preset driving mileage, where the value of the second preset driving mileage is the difference between the vehicle driving end point and the preset distance, the environmental temperature is greater than or equal to the preset temperature threshold, the engine outlet water temperature is less than the preset water temperature threshold, the vehicle battery power is less than the target power corresponding to the power preservation and climbing geographic fence, the vehicle speed is greater than or equal to the preset vehicle speed threshold, the remaining total available driving mileage of the vehicle is greater than or equal to the first preset driving mileage, and the remaining driving time feedback by the navigation is greater than or equal to the preset time threshold.

[0051] For the above activation conditions, the vehicle driving mode should be a non-pure electric driving mode. If the vehicle is currently in pure electric driving mode, it means that the vehicle may need the electric drive system to intervene in auxiliary driving during the non-climbing stage, that is, at this time, it may not be possible to ensure the normal driving of the vehicle only by the engine drive.

[0052] If the vehicle driving mode is in pure electric mode and the vehicle's navigation function is turned on at this time, and the available driving mileage corresponding to the current vehicle power is less than the difference between the target location corresponding to the navigation and the preset distance, it means that the current vehicle power is not enough to support the vehicle to drive to the target location, and the engine should be controlled to charge the battery to meet the user's need to reach the target location, and then the vehicle can also smoothly pass through the climbing section.

[0053] Secondly, ensure that the ambient temperature where the vehicle is currently located is greater than or equal to the preset temperature threshold, to avoid the engine having to run for a long time to reach the target operating temperature in order to meet the normal driving functions of the vehicle due to too low ambient temperature, which may lead to overheating of the engine due to long running time, and further affect the stable operation of the whole vehicle. At the same time, ensure that the water temperature at the engine outlet is less than the preset water temperature threshold. If the water temperature at the engine outlet is too high, using the engine to supply power to the battery may cause excessive engine load and lead to engine damage.

[0054] Finally, when the remaining driving range of the vehicle is low, the power preservation function is no longer triggered to ensure that the user can drive to the destination smoothly. And if the user turns on the navigation and is about to reach the end point, stop charging the battery to reduce unnecessary fuel consumption.

[0055] Exemplarily, the activation condition is that the vehicle driving mode is non-pure electric driving mode, the ambient temperature is greater than or equal to 35 degrees, the water temperature at the engine outlet is less than 106 degrees Celsius, the battery power of the vehicle is less than the target power corresponding to the power preservation climbing geographical fence, the vehicle speed is greater than or equal to 10 km / h and the total remaining driving range of the vehicle is greater than or equal to 100 km.

[0056] Exemplarily, when the remaining driving range of the vehicle is low, the power preservation function is no longer triggered to ensure that the user can drive to the destination smoothly. Another example is that if the user turns on the navigation and is about to reach the end point, stop charging the battery to reduce unnecessary fuel consumption.

[0057] Through the above solution, when receiving the position prompt information and the target power sent by the cloud, this indicates that the vehicle is within the power preservation climbing geographical fence. To ensure the power performance of the vehicle during subsequent climbing, within the power preservation climbing geographical fence range, the vehicle should increase its own battery power. When it is determined that the vehicle operation information and the current environment information meet the preset activation conditions, control the vehicle engine to charge the vehicle battery. Charging the battery after meeting the activation conditions can avoid charging when the current driving state of the vehicle or the environment where the vehicle is located is not suitable, which poses a threat to the stable and safe driving of the vehicle. At the same time, by charging the battery, when climbing later, it can avoid the phenomenon that the battery power is too low and only the engine is relied on to drive the vehicle to climb. The electric drive system is used to assist in driving, reducing the risk of engine overheating and improving the power performance of the whole vehicle. Charge the vehicle battery until the battery power is greater than or equal to the target power, and the target power represents the power that the vehicle battery needs to reach when driving within the power preservation climbing geographical fence, to avoid excessive engine energy consumption caused by continuously charging the battery.

[0058] In some embodiments, after step 102, it further includes:

[0059] Step 10A, monitor the battery power.

[0060] Step 10B, in response to the battery power being less than a preset power threshold, control the vehicle engine to charge the vehicle battery again.

[0061] In specific implementation, when controlling the vehicle engine to charge the vehicle battery and the battery power is greater than or equal to the target power, it indicates that the current battery power of the vehicle is sufficient to meet the subsequent climbing requirements. Continuously monitor the battery power of the vehicle. When it is detected that the battery power is less than the preset power threshold, it indicates that the vehicle battery needs to be charged again until the battery power of the vehicle is greater than or equal to the target power again.

[0062] Exemplarily, the preset power threshold is 10% and the target power is 25%. If the vehicle engine charges the vehicle battery until the battery power of the vehicle is greater than or equal to 25%, monitor the battery power of the vehicle. If it is detected that the battery power of the vehicle is less than 10%, recharge the vehicle battery until the battery power is greater than or equal to 25% again.

[0063] Through the above solution, after charging the battery to make the battery power greater than or equal to the target power, monitor the battery power and change the enabling condition, that is, adjust it to recharge the battery when the battery power is less than the preset power, so as to avoid the problem that the battery power is insufficient during climbing again and only rely on the engine to drive, resulting in an increase in the engine water temperature and affecting the overall vehicle power performance.

[0064] Another embodiment of the present disclosure proposes a vehicle control method, as Figure 2 shown, applied to the cloud, the method includes:

[0065] Step 201, obtain the current position information of the vehicle, and judge whether the vehicle is within the power-preserving climbing geographic fence according to the current position information, wherein the power-preserving climbing geographic fence is determined based on the position information of multiple historical target vehicles with over-temperature faults, and the vehicle operation information, ambient temperature, and road surface slope of the historical target vehicles at the moment of over-temperature fault meet preset conditions.

[0066] In specific implementation, the cloud can obtain the current position information of the vehicle. The cloud pre-stores the area corresponding to the power-preserving climbing geographic fence, which is determined based on the position information of multiple historical target vehicles with over-temperature faults. At the same time, the vehicle operation information, ambient temperature, and road surface slope of the multiple historical target vehicles at the moment of over-temperature fault all meet the preset conditions.

[0067] In this embodiment, the vehicle operation information includes at least one of the following: vehicle speed, vehicle driving mode, vehicle fault information, engine outlet water temperature, and vehicle battery power. The preset condition may specifically be:

[0068] The vehicle speed is greater than a preset vehicle speed threshold, the ambient temperature is greater than a preset ambient temperature threshold, the vehicle driving mode is the engine drive mode, the vehicle has no other faults except for over-temperature faults, the vehicle battery power is less than a preset power threshold, the road surface slope is greater than a preset slope threshold, and the engine outlet water temperature is higher than a preset water temperature threshold for more than a preset time.

[0069] For the above preset conditions, the vehicle driving mode should be the engine drive mode. If the vehicle is currently in the pure electric driving mode or the hybrid mode, it means that the vehicle may need the electric drive system to intervene and assist in driving during the non-climbing stage. That is, at this time, the vehicle performance itself relies on the battery supply. At this time, relying solely on the engine drive may not be able to ensure the normal driving of the vehicle. Furthermore, in this case, the vehicle engine simply cannot supply power to the battery to achieve the effect of maintaining power during climbing.

[0070] Secondly, it is also necessary to ensure that the ambient temperature is greater than a preset ambient temperature threshold and the vehicle has no other faults except for over-temperature faults, indicating that the over-temperature fault of the vehicle at this time is due to the vehicle climbing, resulting in the engine outlet water temperature being higher than the preset water temperature threshold, excluding the problem that the engine speed is too fast and the temperature rises due to the low ambient temperature to maintain normal operation. At the same time, the vehicle has no other faults except for over-temperature faults at this time, avoiding the problem that other faults affect the performance of the engine.

[0071] Exemplarily, the preset condition is that the vehicle speed is greater than 10 km / h, the ambient temperature is greater than 35 degrees Celsius, the vehicle driving mode is the engine drive mode, the vehicle has no other faults except for over-temperature faults, the vehicle battery power is less than 15%, the road surface slope is greater than 5%, and the engine outlet water temperature is higher than 110 degrees Celsius for more than 2 seconds.

[0072] According to the obtained current position information of the vehicle, it is judged whether the vehicle is within the power-preserving climbing geographical fence.

[0073] Step 202, in response to determining that the vehicle is within the power-preserving climbing geographical fence, determine the target power corresponding to the power-preserving climbing geographical fence, and send the target power and the position prompt information to the vehicle;

[0074] Wherein, the position prompt information is used to prompt that the vehicle is within the power-preserving climbing geographical fence.

[0075] During specific implementation, if it is determined that the vehicle is within the power preservation climbing geographic fence, the target power corresponding to the power preservation climbing fence is searched for in the database at this time. The corresponding relationship between the power preservation climbing fence and the power is pre-stored in the database, where the corresponding relationship can be a relational table, a functional relationship, a curve relationship, a key-value pair relationship, and a bar chart relationship.

[0076] The target power and the position prompt information are sent to the vehicle. Among them, the position prompt information is used to prompt that the vehicle is within the power preservation climbing geographic fence. After the vehicle receives the target power and the position prompt information, the vehicle engine is controlled to charge the vehicle battery to the target power.

[0077] Through the above solution, it is determined whether the vehicle is within the power preservation climbing geographic fence according to the current position of the vehicle, and the judgment result is more accurate. After determining that the vehicle is within the power preservation climbing geographic fence, the target power corresponding to the power preservation climbing geographic fence is determined, and the target power and the position prompt information are sent to the vehicle. After the vehicle receives the target power and the position prompt information, the vehicle engine is controlled to charge the vehicle battery to the target power. This avoids the phenomenon that the vehicle relies solely on the engine to drive the vehicle up the slope due to too low battery power during subsequent climbing, adopts the electric drive system to assist in driving, reduces the risk of engine overheating, and improves the overall vehicle power performance.

[0078] In some embodiments, the construction process of the power preservation climbing geographic fence specifically includes:

[0079] Step 20A: Receive the historical position information sent by multiple historical target vehicles, and determine whether to use the historical position information as the historical geographic coordinates. Among them, the historical position information is the position information corresponding to the moment when the historical target vehicle has an over-temperature fault.

[0080] Step 20B: Determine to use the historical position information as the historical geographic coordinates, and determine the power preservation climbing geographic fence according to multiple historical geographic coordinates.

[0081] During specific implementation, after the historical target vehicle determines that its own operation information and its own environmental information meet the preset conditions, that is, at this time, the historical target vehicle has an over-high water temperature at the engine outlet due to climbing, that is, the historical target vehicle has an over-temperature fault. The vehicle sends its own position information to the cloud, and its own position information is the historical position information, that is, the historical position information represents the driving position of the historical target vehicle. The cloud receives the historical position information sent by multiple historical target vehicles, determines the historical geographic coordinates corresponding to each historical position information, and determines whether to use the historical position information as the historical geographic coordinates. The historical geographic coordinates are the coordinate values required for the subsequent power preservation climbing geographic fence, that is, the range corresponding to the geographic coordinates can be constructed as the power preservation climbing geographic fence according to the historical geographic coordinates.

[0082] Determine a power - guarantee climbing geographical fence based on multiple historical geographical coordinates. Exemplarily, 10 historical geographical coordinates are used to determine the power - guarantee climbing geographical fence, and the power - guarantee climbing geographical fence indicates that vehicles in this area are prone to over - temperature faults caused by climbing.

[0083] Through the above - mentioned solution, the power - guarantee climbing geographical fence is determined by using the geographical coordinates where over - temperature faults have been determined to occur, and the construction of the power - guarantee climbing geographical fence is more accurate. At the same time, all historical target vehicles meet the preset conditions, avoiding the generation and preservation of incorrect geographical fence information due to the special or intense driving behaviors of individual vehicles, and avoiding subsequent incorrect activation of the power - guarantee function for other vehicles.

[0084] In some embodiments, step 20A specifically includes:

[0085] Step 20A1, receive the historical location information sent by multiple historical target vehicles;

[0086] Step 20A2, for each historical target vehicle:

[0087] Obtain the vehicle number of the historical target vehicle, and bind the vehicle number to the historical location information;

[0088] In response to the existence of the vehicle number in the database, obtain the historical bound location information corresponding to the vehicle number;

[0089] Determine that the historical location information is different from the historical bound location information, and use the historical location information as the historical geographical coordinate.

[0090] In specific implementation, after the historical target vehicle determines that its own operation information and its own environmental information meet the preset conditions, that is, at this time, the historical target vehicle has an over - high water temperature at the engine outlet due to climbing, that is, the historical target vehicle has an over - temperature fault. The vehicle sends its own location information to the cloud, and the own location information is the historical location information.

[0091] The cloud receives the historical location information sent by multiple historical target vehicles. For each historical target vehicle:

[0092] Obtain the vehicle number of the historical target vehicle. The vehicle number is unique identification information for each vehicle. Exemplarily, the vehicle number is the VIN code, that is, the vehicle identification code, and the vehicle number is bound to the historical location information.

[0093] Judge whether the vehicle number is stored in the database. If the vehicle number does not exist, store the vehicle number and the historical location information in the database correspondingly, and use the historical location information as the historical geographical coordinate.

[0094] If the vehicle number already exists in the database, retrieve the historical binding location information corresponding to the vehicle number in the database, compare the historical location information with the historical binding location information, and determine whether the historical location information is the same as the historical binding location information.

[0095] If the historical location information is the same as the historical binding location information, it means that the location of the vehicle corresponding to the vehicle number has already been stored in the database, and there is no need to add it repeatedly.

[0096] If the historical location information is different from the historical binding location information, at this time, store the vehicle number and the historical location information corresponding to each other in the database, and use the historical location information as the historical geographical coordinates.

[0097] Through the above solution, use the vehicle number to determine whether the location of the vehicle has been stored before, avoid repeatedly adding the same location of the same vehicle, and reduce the resource occupation.

[0098] In some embodiments, step 20B specifically includes:

[0099] Step 20B1, determine a first target area with a regional radius of a first preset radius and containing the multiple historical geographical coordinates at the same time, and use the first target area as the initial power preservation climbing geographical fence.

[0100] Step 20B2, determine a second target area with the same fence center as the initial power preservation climbing geographical fence and a regional radius of a second preset radius, and use the second target area as the power preservation climbing geographical fence, where the second preset radius is greater than the first preset radius.

[0101] During specific implementation, determine a first target area with a regional radius of a first preset radius and containing the multiple historical geographical coordinates at the same time, and use the first target area as the initial power preservation climbing geographical fence.

[0102] Taking the fence center of the initial power preservation climbing geographical fence as the center of the circle, determine a second target area with the same fence center as the initial power preservation climbing geographical fence and a regional radius of a second preset radius, and use the second target area as the power preservation climbing geographical fence, where the second preset radius is greater than the first preset radius.

[0103] Exemplarily, such as Figure 3As shown in the figure, the first preset radius is 4 km, the second preset radius is 10 km, the historical geographical coordinates are 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 1-10 respectively, the preset quantity is 10, and the first target area A that simultaneously includes 10 historical geographical coordinates is used as the initial power preservation climbing geographical fence, and the radius of the first target area A is 4 km. The second target area B with the same center as the center of the first target area A is used as the power preservation climbing geographical fence, and the radius of the second target area B is 10 km.

[0104] Through the above solution, after determining the initial power preservation climbing geographical fence that includes multiple historical geographical coordinates, a region with the same center as the initial power preservation climbing geographical fence and a larger radius is selected as the power preservation climbing geographical fence, so that subsequent vehicles can enter the power preservation climbing geographical fence earlier, and then carry out charging measures earlier, avoiding the problem that the range of the power preservation climbing geographical fence is small and the charging time left for the vehicle is short, resulting in the inability to charge to the target power, further reducing the risk of engine overheating and improving the vehicle's power performance.

[0105] In some embodiments, after step 20B, it further includes:

[0106] Step 20B1, determining the reception time of each historical geographical coordinate among the multiple historical geographical coordinates included in the power preservation climbing geographical fence.

[0107] Step 20B2, in response to the reception time of the target historical geographical coordinate among the multiple historical geographical coordinates being greater than the preset time threshold, deleting the power preservation climbing geographical fence.

[0108] Specifically in implementation, after receiving the historical position information sent by the historical target vehicle, timing starts, and the reception time of each historical geographical coordinate among the multiple historical geographical coordinates included in the power preservation climbing geographical fence is counted, where the reception time represents the total duration from the moment when the historical position information corresponding to this historical geographical coordinate is received to the current moment.

[0109] Each reception time is compared with the preset time threshold respectively. If there is a target historical geographical coordinate among the multiple historical geographical coordinates whose reception time is greater than the preset time threshold, the power preservation climbing geographical fence is deleted.

[0110] Exemplarily, the preset time threshold is 550 days. If there is a historical geographical coordinate with a reception time exceeding 550 days among the 10 historical geographical coordinates included in the power preservation climbing geographical fence, then the power preservation climbing geographical fence is deleted.

[0111] In some embodiments, there may still be historical geographical coordinates in the cloud that do not form a power-preserving climbing geographical fence. The preset time threshold corresponding to such historical geographical coordinates is 30 days. That is, if the historical geographical coordinates still do not form a power-preserving climbing geographical fence with other historical geographical coordinates within 30 days, the historical geographical coordinates will be deleted.

[0112] Through the above solution, the reception time of the historical geographical coordinates included in the power-preserving climbing geographical fence is limited. If the preset time threshold is exceeded, the power-preserving climbing geographical fence will be deleted, realizing the update of the power-preserving climbing geographical fence stored in the cloud, which is more in line with the current working conditions of the vehicle. For the situation where the engine load decreases due to road conditions changes over time, an opportunity to delete the power-preserving climbing geographical fence already stored in the cloud is provided, reducing unnecessary pre-power-preserving behaviors in the future.

[0113] In some embodiments, step 202 specifically includes:

[0114] Step 2021, in response to determining that the vehicle is in the common area of at least two initial power-preserving climbing geographical fences, determine the first power corresponding to each initial power-preserving climbing geographical fence where the vehicle is located;

[0115] Step 2022, take the maximum value among all the first powers as the target power, and take the power-preserving climbing geographical fence corresponding to the target power as the target geographical fence;

[0116] Step 2023, send the target power and the position prompt information corresponding to the target geographical fence to the vehicle.

[0117] Specifically, when it is monitored that the vehicle enters the common area of at least two initial power-preserving climbing geographical fences, the database is searched at this time to determine the first power corresponding to each initial power-preserving climbing geographical fence.

[0118] Count all the first powers, filter out the maximum value among all the first powers, take the maximum value as the target power, and take the power-preserving climbing geographical fence corresponding to the maximum value as the target geographical fence. Send the target power and the position prompt information corresponding to the target geographical fence to the vehicle.

[0119] Exemplarily, such as Figure 4As shown, there is a common area C between the initial power preservation climbing geographic fence A and the initial power preservation climbing geographic fence B. The historical geographic coordinates included in the initial power preservation climbing geographic fence A are 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 1-10 respectively, and the historical geographic coordinates included in the initial power preservation climbing geographic fence B are 2-1, 2-2, 2-3, 2-4, 2-5, 2-6, 2-7, 2-8, 2-9, 2-10, 2-11 respectively. The common area C includes 1-7 in the initial power preservation climbing geographic fence A and 2-11 in the initial power preservation climbing geographic fence B respectively.

[0120] Determine the power preservation climbing geographic fence corresponding to the initial power preservation climbing geographic fence A , and the power preservation climbing geographic fence corresponding to the initial power preservation climbing geographic fence B . Respectively search to obtain that the first power corresponding to the power preservation climbing geographic fence is 10%, and the first power corresponding to the power preservation climbing geographic fence is 20%. Then the target power can be determined to be 20%, and the power preservation climbing geographic fence is used as the target geographic fence. Send the target power and the position prompt information corresponding to the target geographic fence to the vehicle.

[0121] Through the above solution, when the position where the vehicle is located belongs to the common area of at least two initial power preservation climbing geographic fences at the same time, at this time, select the maximum value of the power in at least two initial power preservation climbing geographic fences as the target power, so as to avoid the target power being selected too small, resulting in repeated charging of the battery and damage to the battery. At the same time, when sending the position prompt information, only send the position prompt information once, so as to avoid causing user annoyance due to repeated sending.

[0122] In some embodiments, the process of determining the first power corresponding to each power preservation climbing geographic fence, for each power preservation climbing geographic fence, specifically includes:

[0123] Step A, obtain the number of geographic coordinates and the initial power in the initial power preservation geographic fence corresponding to the power preservation climbing geographic fence;

[0124] Step B, in response to the number of the geographic coordinates being less than or equal to the preset number threshold, use the initial power as the first power corresponding to the power preservation climbing geographic fence; or,

[0125] Step C, in response to the number of the geographic coordinates being greater than the preset number threshold, determine the target growth gradient according to the number of the geographic coordinates, and determine the first power corresponding to the power preservation climbing geographic fence according to the target growth gradient and the initial power.

[0126] During specific implementation, obtain the number of geographical coordinates and the initial power in the initial power preservation geographical fence corresponding to the power preservation climbing geographical fence, where the initial power is a preset power value. If the number of geographical coordinates is less than or equal to a preset number threshold, use the initial power as the first power corresponding to the power preservation climbing geographical fence.

[0127] Exemplarily, the preset number threshold is 20 and the initial power is 30%. If the number of geographical coordinates obtained in the initial power preservation geographical fence A corresponding to the power preservation climbing geographical fence is 15, then determine that the first power corresponding to the power preservation climbing geographical fence is 30%.

[0128] If the number of geographical coordinates is greater than the preset number threshold, determine a target growth gradient according to the number of geographical coordinates. In this embodiment, the target growth gradient is positively correlated with the number of geographical coordinates. Perform an arithmetic operation on the target growth gradient and the initial power to obtain the first power corresponding to the power preservation climbing geographical fence.

[0129] In this embodiment, the relationship between the target growth gradient and the number of geographical coordinates is specifically:

[0130] Determine the initial ratio value between the number of geographical coordinates in the initial power preservation geographical fence and the preset number threshold. If the initial ratio value is a decimal, round up to obtain the target ratio value. Perform a multiplication operation on the target ratio value and a preset initial power adjustment value to obtain a power adjustment value. Perform an addition operation on the power adjustment value and the initial power to obtain the first power.

[0131] Exemplarily, if the number of geographical coordinates obtained in the initial power preservation geographical fence B corresponding to the power preservation climbing geographical fence is 45, the preset number threshold is 20, the initial power adjustment value is 5%, and the initial power is 30%. Calculate the ratio of the number of geographical coordinates in the initial power preservation geographical fence to the preset number threshold to obtain an initial ratio value of 2.25. After rounding up, the target ratio value is 3. Perform a multiplication operation on the target ratio value and the preset initial power adjustment value to obtain a power adjustment value of 15%. Perform an addition operation on the power adjustment value and the initial power to obtain the first power of 45%.

[0132] In this embodiment, the upper limit value of the first power corresponding to the power-preserving climbing geographic fence is defined. That is, no matter how many geographic coordinates in the initial power-preserving geographic fence corresponding to the power-preserving climbing geographic fence increase, the calculated first power is at most the upper limit value, so as to avoid the problem that the first power is too large, resulting in excessive energy consumption of the engine after the first power is used as the target power and the vehicle engine charges the battery to the target power, and even the engine is insufficient to support the normal operation of the vehicle.
