[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The vehicle energy replenishment method and energy replenishment determination device according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Figure 1 It is a flow chart of a vehicle energy replenishment method according to an embodiment of the present invention.

[0029] like Figure 1 As shown, the vehicle energy replenishment method may include:

[0030] S11: Obtain at least one of an energy replenishment index, a distance index, a congestion index and an estimated index for each target service area in a plurality of target service areas ahead of the target vehicle.

[0031] Among them, the energy replenishment index is used to indicate the current energy replenishment queue of the target vehicle in the target service area. The energy replenishment methods include but are not limited to electricity replenishment, fuel replenishment and hydrogen replenishment. Different types of vehicles correspond to different energy replenishment methods. Among them, the target vehicle is the vehicle for energy replenishment service, usually the vehicle itself. The target vehicle can be determined through the vehicle terminal or user terminal, or through the cloud platform. The target service area is the service area where the target vehicle can be recharged. The number of target service areas can be one or more.

[0032] Specifically, the energy replenishment index is related to the estimated length of the energy replenishment queue in the target service area in the current time period, which is affected by parameters such as the number of vehicles to be recharged in the target service area in the current time period, the number of remaining energy replenishment equipment that can be recharged normally, and the recharge time required for the vehicles to be recharged. If the remaining power or remaining fuel of the target vehicle is lower, the possibility of the target vehicle recharging is higher. At this time, it is necessary to judge the energy replenishment index of the target service area in the current time period where the target vehicle is located. It can be understood that if the target vehicle is located in a certain target service area A in the current time period where the target vehicle is located, the more vehicles to be recharged, the fewer remaining energy replenishment equipment that can be recharged normally, and the longer the time required for the vehicles to be recharged, the longer the estimated queuing time for the target vehicle to be recharged in the target service area A. At this time, it can be determined that the energy replenishment index of the target service area A is higher; if the target vehicle In the current time period, there are fewer vehicles waiting to be recharged in a certain target service area B, and there are more remaining recharging equipment that can perform normal recharging operations. The shorter the recharging time required for the vehicles waiting to be recharged, the shorter the estimated queuing time for the target vehicles to be recharged in the target service area B. At this time, it can be determined that the recharging index of the target service area B is low. Therefore, the recharging index of the target service area represents the current recharging queuing situation of the target vehicles in the target service area. The larger the recharging index, the longer the target vehicles are expected to queue for recharging in the target service area, and the more serious the recharging queuing situation.

[0033] The distance index is used to indicate the probability that the target vehicle can reach the target service area. Each target service area obtains a corresponding distance index. The probability that the target vehicle can reach the target service area is related to the distance between the target vehicle and the target service area. If the distance between the target vehicle and the target service area A is closer, the probability that the target vehicle can reach the target service area A is greater. If the distance between the target vehicle and the target service area B is farther, the probability that the target vehicle can reach the target service area B is smaller, that is, the larger the distance index, the smaller the probability that the target vehicle can reach the target service area. By counting the probability that the target vehicle can reach each target service area, it is helpful for the user of the target vehicle to determine the target service area for energy replenishment.

[0034] When the target vehicle is traveling on the highway, the navigation software will count the number and location of service areas within a certain distance in the navigation path, and display them to the user of the target vehicle. For example, if the number of service areas within 100 kilometers ahead in the navigation path is 3, it can be determined that the average distance between the target vehicle and the nearest target service area is 30 kilometers. At this time, the user of the target vehicle has greater selectivity for energy replenishment services; if the number of service areas within 100 kilometers ahead in the navigation path is 2, it can be determined that the average distance between the target vehicle and the nearest target service area is 50 kilometers. At this time, the user of the target vehicle has less selectivity for energy replenishment services. The size of the distance index can be represented by the average distance between the target vehicle and the target service area. The larger the average distance between the target vehicle and the target service area, the larger the distance index, and the smaller the probability that the target vehicle can reach the target service area. By counting the probability that the target vehicle can reach each target service area, it is helpful for the user of the target vehicle to determine the target service area for energy replenishment.

[0035] The congestion index is used to indicate the road congestion situation from the target vehicle to the target service area. Each target service area obtains the corresponding congestion index. In order to facilitate the user of the target vehicle to determine the target service area for recharging the target vehicle, the road congestion situation from the target vehicle to each target service area is obtained as a reference. The road congestion situation is obtained by monitoring the traffic conditions between the target vehicle and each target service area in the navigation path of the target vehicle based on GPS technology through the navigation software. The larger the congestion index of a target service area A, the more serious the road congestion situation from the target vehicle to the target service area A.

[0036] It can be understood that when the target vehicle is on a congested road, it often needs to wait for a long time before it can pass. If the target vehicle is still in the ignition state or the air conditioner in the car is turned on, the remaining power or remaining fuel of the target vehicle will continue to decrease. As the power or fuel of the target vehicle is consumed, the possibility of the target vehicle replenishing energy in the target service area A will increase. That is, the more serious the road congestion from the target vehicle to a certain target service area, the greater the congestion index of the target service area.

[0037] The estimated index is used to indicate the newly added charging queue in the target service area during the time when the target vehicle arrives at the target service area. Each target service area obtains a corresponding estimated index. As the target vehicle travels toward the target service area A, the number of other vehicles in the target service area A that need to be charged gradually increases during the time when the target vehicle arrives at the target service area A. The remaining power or remaining fuel of the target vehicle will gradually decrease, and the possibility of the target vehicle charging in the target service area A will increase. At this time, the estimated charging queue time of the target vehicle in the target service area A indicated by the estimated index will also gradually increase with the increase in the number of other vehicles that need to be charged.

[0038] In summary, at least one of the energy replenishment index, distance index, congestion index and estimated index of each of the multiple target service areas in front of the target vehicle is determined, so as to estimate the expected energy replenishment queuing time of each of the multiple target service areas in front of the target vehicle, thereby helping the user of the target vehicle to select the target service area for recharging the target vehicle.

[0039] It can be understood that vehicle data such as vehicle location information, mileage, road conditions or remaining power information is uploaded to the cloud platform through the vehicle-mounted terminal or the user terminal, and the charging pile terminal will upload charging pile data such as the number of vehicles queuing for the charging pile, the number of idle charging piles, the remaining power of the charging pile, the remaining fuel amount or the remaining hydrogen amount to the cloud platform, and at least one of the charging index, distance index, congestion index and estimated index is obtained through calculation on the cloud platform, thereby providing users with charging estimates in highway service areas.

[0040] S13: Determine the energy replenishment queuing index of each target service area according to at least one of the energy replenishment index, distance index, congestion index and estimated index corresponding to the target vehicle, so as to select a target service area from multiple target service areas to recharge the target vehicle based on the energy replenishment queuing index.

[0041] Specifically, the charging queue index is used to determine whether the target vehicle is recharging in the target service area. The charging queue index can indicate the number of vehicles waiting to be recharged in each target service area. The higher the charging queue index, the more vehicles waiting to be recharged in the target service area. If the target vehicle is recharging in the target service area, the expected waiting time for recharging will also be longer.

[0042] It can be understood that when the target vehicle is already in the target service area or is about to arrive at the target service area, the energy replenishment index can be used to estimate the expected queuing time of the target vehicle in the target service area. At this time, the energy replenishment index of the target service area can be used as the energy replenishment queue index. When the target vehicle is still on the highway and is far away from multiple target service areas ahead, at least one of the energy replenishment index, distance index, congestion index and estimated index between the target vehicle and each of the multiple target service areas ahead can be obtained, and the obtained indexes are summed to obtain the energy replenishment queue index of each target service area, so that the user of the target vehicle can select a target service area for energy replenishment service from multiple target service areas according to the size of the energy replenishment queue index. Under normal circumstances, the user of the target vehicle can select a target service area with a smaller energy replenishment queue index, which can reduce the expected waiting time for energy replenishment.

[0043] When the target vehicle is traveling on the highway, the vehicle terminal or the user terminal will upload vehicle data such as the vehicle's location information, mileage, road conditions or remaining power information to the cloud platform, and the charging pile terminal will upload the charging pile data to the cloud platform. The charging index of the target service area is obtained through the cloud platform calculation to estimate the current charging queue situation of the target vehicle in the target service area, and the probability of the target vehicle reaching the target service area is estimated through the distance index calculated by the cloud platform. The congestion index calculated by the cloud platform is used to estimate the road congestion situation from the target vehicle to the target service area, and the estimated index calculated by the cloud platform is used to estimate the newly added charging queue situation of the target service area during the target vehicle's arrival at the target service area, so as to sum the obtained charging index, distance index, congestion index and estimated index of each target service area to obtain the charging queue index of the target vehicle in each target service area, and send the charging queue index corresponding to each target service area to the vehicle terminal display interface or the user terminal display interface, so that the user can comprehensively determine the target service area for charging the target vehicle in combination with the remaining power of the target vehicle.

[0044] Exemplarily, the target service areas are A and B, and the value range of the energy replenishment queue index is 0-10, wherein 0-2 indicates that the number of vehicles to be replenished in the target service area is normal, 2-4 indicates that the number of vehicles to be replenished in the target service area is basically normal, 4-6 indicates that the number of vehicles to be replenished in the target service area is slightly congested, and 6-10 indicates that the number of vehicles to be replenished in the target service area is severely congested; the target vehicle is determined to be in the target service area according to at least one of the energy replenishment index, distance index, congestion index and estimated index of the target service area A and the target service area B respectively. The charging queue index of the target service area A is between 6 and 10, and the charging queue index of the target service area B is between 2 and 4. At this time, it is considered that the number of vehicles waiting to be charged in the target service area A is severely congested, and the number of vehicles waiting to be charged in the target service area B is basically normal; then the user determines the target service area for charging the target vehicle according to the charging queue indexes corresponding to the target service areas A and B and the remaining power or remaining fuel of the target vehicle. If the target vehicle has a large amount of remaining power and the user wants to reach the destination quickly, the target vehicle can be charged in the target service area B.

[0045] It should be noted that the energy replenishment index, distance index, congestion index and estimated index of each target service area can be displayed separately on the details page of the vehicle terminal display interface or the user terminal display interface, or the energy replenishment queuing index of each service area determined by at least one of the energy replenishment index, distance index, congestion index and estimated index can be directly displayed to the user.

[0046] In the above embodiment, the energy replenishment queuing index of the target vehicle in multiple target service areas is determined based on at least one of the acquired energy replenishment index, distance index, congestion index and estimated index of the target service area, so as to reasonably estimate the energy replenishment queuing conditions of the multiple target service areas based on the energy replenishment queuing index, so that the user can select a suitable energy replenishment service area based on the energy replenishment queuing index to improve the energy replenishment efficiency of the vehicle.

[0047] In some embodiments, reference Figure 2 , obtain the energy replenishment index of the target service area, including:

[0048] S111: Obtain the number of charging piles in the target service area and the charging efficiency of each vehicle to be charged.

[0049] The number of charging piles in the target service area is obtained. If the number of charging piles in the target service area is smaller and the number of vehicles to be charged is larger, the estimated charging queue time of the target vehicle in the target service area will be longer. The charging efficiency of the vehicle to be charged refers to the efficiency of the charging pile in charging the vehicle to be charged. The charging efficiency is determined based on the remaining power or remaining fuel of the vehicle to be charged. If the remaining power or remaining fuel of the vehicle to be charged is low, a higher charging efficiency is required to charge the vehicle to be charged to ensure efficient use of the vehicle to be charged.

[0050] In some embodiments, obtaining the recharging efficiency of each vehicle to be recharged includes: obtaining the remaining power or the remaining fuel of each vehicle to be recharged, and determining the power interval corresponding to the remaining power or the fuel amount interval corresponding to the remaining fuel amount; determining the recharging time for the vehicle to be recharged to be recharged to a target power according to the power interval, or determining the recharging time for the vehicle to be recharged to be recharged to a target fuel amount according to the fuel amount interval; determining the recharging efficiency of each vehicle to be recharged according to the recharging time and the target power or the target fuel amount.

[0051] Among them, different power intervals and different target fuel amounts correspond to different charging durations, and the target power and the charging duration are preset before leaving the factory and can be adjusted according to actual conditions. Since the charging efficiency of each vehicle to be charged adopts the average charging efficiency in each power interval or each fuel amount interval, the charging efficiency of each vehicle to be charged in the same power interval or the same fuel amount interval is the same.

[0052] That is to say, by counting the vehicles to be recharged in the target service area, the remaining power or remaining fuel amount of each vehicle to be recharged is obtained, and the power interval or fuel amount interval corresponding to each vehicle to be recharged is determined according to the obtained remaining power or remaining fuel amount, and then different recharging times corresponding to the recharging of the vehicle to be recharged to the target power are determined according to the different power intervals divided, or different recharging times corresponding to the recharging of the vehicle to be recharged to the target fuel amount are determined according to the different fuel amount intervals divided, so that the recharging efficiency of each vehicle to be recharged corresponding to the different power intervals is obtained according to the product of each recharging time and the target power, or the recharging efficiency of each vehicle to be recharged corresponding to the different fuel amount intervals is obtained according to the product of each recharging time and the target fuel amount.

[0053] S112: Determine the recharging time of the vehicle to be recharged according to the recharging efficiency of each vehicle to be recharged.

[0054] Furthermore, after obtaining the energy charging efficiency of each vehicle to be charged corresponding to different power intervals or different fuel amount intervals, the energy charging time of the vehicle to be charged is obtained according to the product of the energy charging efficiency of each vehicle to be charged corresponding to different power intervals or different fuel amount intervals and the number of vehicles to be charged. The energy charging time of the vehicle to be charged represents the total energy charging time required for each vehicle to be charged in different power intervals to charge to the target power or target fuel amount with the same energy charging efficiency.

[0055] S113: Determine the total charging time of a single charging pile according to the charging time of the vehicle to be charged and the number of charging piles.

[0056] The number of charging piles indicates the number of charging piles that can be used to recharge vehicles in the target service area. The total recharging time of a single pile indicates the total recharging time provided by a single charging pile for all vehicles that use the charging pile for recharging within a period of time. The total recharging time of a single charging pile in the target service area can be determined based on the ratio between the recharging time of the vehicles to be recharged and the number of charging piles.

[0057] S114: Determine an energy replenishment index according to the total energy replenishment time of a single pile and the energy replenishment time of a single pile.

[0058] The single-pile charging time indicates the average charging time taken by each vehicle to be charged to recharge to the target power or target fuel amount on a single charging pile. The single-pile charging time can be selected based on the historical charging time data uploaded by the charging pile, and the average charging time can be determined as the single-pile charging time. The single-pile charging time set by different manufacturers is different. The single-pile charging time can also be set according to the charging time with the largest number of vehicles to be charged in the power interval corresponding to the remaining power of the target vehicle, or according to the charging time with the largest number of vehicles to be charged in the fuel amount interval corresponding to the remaining fuel amount of the target vehicle.

[0059] After determining the total charging time and the charging time of a single charging pile, the number of vehicles that can be recharged by an average single charging pile in the target service area will be determined based on the ratio between the total charging time and the charging time of a single charging pile. The number of vehicles to be recharged will be expressed as a charging index, and the charging index of the target service area will be displayed separately to the user.

[0060] Exemplarily, the energy replenishment index is calculated by combining the experimental data of the following parameters: power range, number of vehicles to be replenished, duration of replenishment of vehicles to be replenished, energy replenishment efficiency, duration of replenishment, and target power:

[0061] Table 1

[0062]

[0063]

[0064] As can be seen from Table 1, the remaining power of the vehicle to be replenished corresponds to four power intervals: (0, 25%], (25%, 50%], (50%, 75%] and (75%, 100%]. The number of vehicles to be replenished in each power interval is different, and the target power is 80%; according to the four power intervals, the replenishment time for the vehicle to be replenished to replenish the target power of 80% is determined to be 30 minutes, 20 minutes, 10 minutes and 5 minutes respectively, and according to the product of the replenishment time corresponding to the four power intervals of 30 minutes, 20 minutes, 10 minutes and 5 minutes and the target power of 80%, the energy replenishment efficiency of each vehicle to be replenished in different power intervals is determined to be 24 minutes, 16 minutes, 8 minutes and 4 minutes respectively; then, according to the product of the energy replenishment efficiency of each vehicle to be replenished in different power intervals and the number of vehicles to be replenished, the energy replenishment time of the vehicle to be replenished is obtained to be 720 minutes, 288 minutes, 120 minutes and 0 minutes respectively.

[0065] Furthermore, the total charging time of a single pile is determined according to the sum of the ratios between the charging time of the vehicles to be charged and the number of charging piles corresponding to different power intervals. For example, if the number of charging piles is 8, the total charging time of a single pile is (720 / 8)+(288 / 8)+(120 / 8)+(0 / 8)=141 minutes. Thus, the charging index is determined according to the ratio between the total charging time of a single pile and the charging time of a single pile. The charging time of a single pile can be determined according to the charging time of the largest number of vehicles to be charged in the above four power intervals. The duration is set to ensure the robustness of the energy replenishment index and to be more in line with the actual usage scenario. For example, the total energy replenishment time of a single pile is 141 minutes, and the energy replenishment time corresponding to the power interval (0, 25%] is 30 minutes as the single pile energy replenishment time. At this time, the energy replenishment index is determined to be 141 / 30=4.7. Therefore, the energy replenishment index is sent to the cloud to calculate the energy replenishment queuing index. At the same time, the energy replenishment index can also be sent to the details page of the vehicle terminal display interface or the user terminal display interface for separate display.

[0066] In this way, by acquiring and calculating the energy replenishment index based on the above parameters, the current energy replenishment queue situation of the target vehicle in the target service area can be timely estimated according to the change of the energy replenishment index, so that users can make better energy replenishment decisions and improve driving efficiency.

[0067] In some embodiments of the present invention, reference Figure 3 , get the distance index of the target service area, including:

[0068] S115: Obtain the number of service areas within a preset distance in front of the target vehicle and the remaining driving range of the target vehicle.

[0069] Specifically, the preset distance is pre-set according to the distance between service areas on the highway. Normally, a service area is set up every 50 to 100 kilometers on my country's highways. Therefore, by obtaining the number of service areas within the preset distance, it helps the target vehicle to determine the location of the service area for energy replenishment. The remaining cruising range of the target vehicle refers to the cruising range that the remaining power of the target vehicle can support the target vehicle to continue driving.

[0070] S116: Obtain a probability according to the preset distance, the number of service areas, and the remaining driving range as a distance index.

[0071] After determining the number of service areas within the preset distance and the remaining cruising range of the target vehicle, the corresponding probability is obtained according to the ratio of the preset distance to the number of service areas and the remaining cruising range, and the probability is used as the distance index. For example, the preset distance is 100 kilometers, the number of service areas within 100 kilometers is 2, and the remaining cruising range is 100 kilometers. According to the preset distance / number of service areas / remaining cruising range, the distance index is 100 kilometers / 2 / 100 kilometers = 0.5. Among them, the preset distance can be adjusted according to actual conditions. The smaller the distance index, the more service areas there are within the preset distance in front of the target vehicle, and the more target service areas the target vehicle has for energy replenishment services. By counting the probability that the target vehicle can reach each target service area, it is helpful for the user of the target vehicle to determine the target service area for energy replenishment.

[0072] For example, when the target vehicle is still on the highway and is far away from multiple target service areas ahead, the distance index between the target vehicle and each of the multiple target service areas ahead can be obtained, so that the user of the target vehicle can select the target service area for recharging the target vehicle. If the distance index of a target service area A is large, it means that the number of target service areas within the preset distance ahead of the vehicle is small, and the target vehicle is far away from the target service area A. After adding the distance index to the recharging queue index of the target service area A, the recharging queue index will be large, and the expected recharging queue time of the target vehicle in the target service area A will also be long; if the distance index of a target service area B is small, it means that the number of target service areas within the preset distance ahead of the target vehicle is large, and the target vehicle is close to the target service area B. Similarly, after adding the distance index to the recharging queue index, the recharging queue index and the expected queuing time for recharging of the target service area B will be small. Therefore, the target vehicle can preferably perform recharging service in the target service area B.

[0073] In this way, by obtaining the number of service areas and the remaining driving range within a preset distance ahead of the target vehicle during its driving process and calculating the distance index corresponding to the target vehicle, the energy replenishment queue index can be obtained more comprehensively, thereby improving the accuracy of the energy replenishment queue index.

[0074] It should be noted that when the remaining cruising range is less than the preset distance and the number of service areas within the preset distance is 0, it is considered that the remaining power of the target vehicle is insufficient to support the target vehicle to travel to the service area closest to the current position of the target vehicle for recharging. Therefore, it is necessary to trigger the recharging prompt information immediately. If the preset distance is 100 kilometers, the recharging prompt information may be: Please get off the highway for recharging, there is no recharging service area within 100 kilometers ahead.

[0075] In some embodiments of the present invention, the vehicle energy replenishment method further includes: obtaining the remaining mileage of the target vehicle to the destination; when the sum of the remaining mileage and the preset mileage is less than the remaining driving range, determining that the distance index is zero.

[0076] The remaining mileage is usually calculated by the navigation software based on the distance between the current position of the target vehicle and the destination. In order to prevent the target vehicle's remaining power or remaining fuel from gradually decreasing due to air conditioning or other reasons during driving, a preset mileage is set to determine whether the target vehicle can successfully reach the destination. The preset mileage is pre-set, and the specific value can be set according to the ambient temperature of the target vehicle. If the weather is cold or hot, the user is more likely to turn on the air conditioner, and the remaining power or remaining fuel of the target vehicle will gradually decrease. At this time, the preset mileage can be set to a larger value.

[0077] Exemplarily, after the user inputs the departure point and destination of the target vehicle in the navigation software, the remaining mileage from the current position of the target vehicle to the destination can be obtained through the navigation software, such as: the remaining mileage is 50 kilometers, the preset mileage is 20 kilometers, and the remaining cruising range is 100 kilometers. The sum of the remaining mileage and the preset mileage, 70 kilometers, is less than the remaining cruising range of 100 kilometers. At this time, it can be considered that the remaining power or remaining fuel of the target vehicle is sufficient to travel to the destination, so the distance index is determined to be zero, and the distance index can be ignored when determining the energy replenishment queuing index.

[0078] In this way, by comparing the sum of the remaining mileage and the preset mileage with the remaining driving range, the distance index can be determined more accurately.

[0079] In some embodiments of the present invention, reference Figure 4 , obtain the congestion index corresponding to the target vehicle, including:

[0080] S117: Obtain the road congestion distance and congestion degree from the target vehicle to the target service area.

[0081] The road congestion distance and congestion degree can usually be obtained through the congestion information prompted by the navigation software. The congestion degree can be divided into four levels: smooth, slow, congested and severe congestion. When the road congestion from the target vehicle to the target service area is serious, it often takes a long time to wait before passing. If the target vehicle is still in the ignition state or the air conditioner in the car is turned on, the remaining power or remaining fuel of the target vehicle will continue to decrease. At this time, the possibility of the target vehicle replenishing energy in the target service area will increase. Therefore, it is necessary to obtain the road congestion distance and congestion degree from the target vehicle to the target service area as a basis for judging the energy replenishment queuing index.

[0082] The larger the congestion index of a target service area A, the more serious the road congestion from the target vehicle to the target service area A. It can be understood that when the target vehicle is on a congested road, it often needs to wait for a long time before passing. If the target vehicle is still in the ignition state or the air conditioner in the car is turned on, the remaining power or remaining fuel of the target vehicle will continue to decrease. As the power or fuel of the target vehicle is consumed, the possibility of the target vehicle replenishing energy in the target service area A will increase. That is, the more serious the road congestion from the target vehicle to a target service area, the greater the congestion index of the target service area.

[0083] S118: Determine a congestion weight corresponding to the congestion degree.

[0084] To ensure the accuracy of the congestion index, different congestion weights are set for different congestion levels. Generally, the more severe the congestion, the greater the corresponding congestion weight. The congestion weight can be weighted in units of 10 kilometers. For example, if the road congestion distance corresponding to severe congestion is 20 kilometers, and the weight of severe congestion is set to 0.15 for every 10 kilometers, the congestion weight corresponding to the severe congestion is 0.15+0.15, that is, the congestion weight is 0.3.

[0085] S119: Determine a congestion index according to the congestion weight and the road congestion distance.

[0086] The larger the congestion index, the more serious the road congestion from the target vehicle to the target service area A, and the more electricity or fuel the target vehicle consumes. As the electricity or fuel of the target vehicle is consumed, the possibility of the target vehicle replenishing energy in the target service area A will increase. That is, the more serious the road congestion from the target vehicle to a certain target service area, the greater the congestion index of the target service area.

[0087] For example, when the target vehicle is still on the highway and is far away from multiple target service areas ahead, the congestion index of the target vehicle and each of the multiple target service areas ahead can be obtained, so that the user of the target vehicle can select the target service area for recharging the target vehicle. If the congestion index of a certain target service area A is large, it means that during the period when the target vehicle reaches the target service area A, the possibility of the target vehicle recharging in the target service area A will increase. After the congestion index is added to the recharging queue index of the target service area A, the recharging queue index will be large, and the estimated recharging queue time for recharging in the target service area A will be longer; if the congestion index of a certain target service area B is small, it means that during the period when the target vehicle reaches the target service area B, the possibility of the target vehicle recharging in the target service area B will decrease. Similarly, after the congestion index is added to the recharging queue index, the recharging queue index and the estimated recharging queue time will also be small. Therefore, the target vehicle can preferably perform recharging service in the target service area B.

[0088] Exemplarily, the distance index is calculated by combining the experimental data of the following parameters: congestion degree, congestion distance and congestion weight:

[0089] Table 2

[0090]

[0091] As can be seen from Table 2, the total road congestion distance from the target vehicle to the target service area is 30 kilometers, of which the congestion level of 10 kilometers is "congested", and the corresponding congestion weight is 0.1 for every 10 kilometers, and the congestion level of 20 kilometers is "severely congested", and the corresponding congestion weight is 0.15 for every 10 kilometers. Therefore, the congestion index is 0.4 (0.1+0.15+0.15).

[0092] In this way, the congestion index can be accurately obtained according to the congestion weight corresponding to the road congestion removal and the congestion degree, which further improves the accuracy of the energy replenishment queuing index, allowing users to make better energy replenishment decisions and improve driving efficiency.

[0093] In some embodiments of the present invention, reference Figure 5 , obtain the estimated index corresponding to the target vehicle, including:

[0094] S120: Obtain the remaining power or remaining fuel of the newly added vehicles to be recharged in the target service area during the period when the target vehicle arrives at the target service area and the number of recharging piles in the target service area.

[0095] During the process of the target vehicle traveling from its own vehicle position to the target service area, the remaining power or remaining fuel of the target vehicle gradually decreases, the remaining power or remaining fuel of other vehicles to be recharged will also gradually decrease, and the number of newly added vehicles to be recharged will also gradually increase. Therefore, it is necessary to obtain the remaining power or remaining fuel of the newly added vehicles to be recharged in the target service area during the period when the target vehicle arrives at the target service area uploaded by the on-board terminal or the user terminal, and obtain the number of charging piles uploaded by the charging pile terminal in the target service area, so as to estimate the new charging situation.

[0096] S121: Determine a power interval corresponding to the remaining power and determine an estimated weight corresponding to the power interval, or determine a fuel amount interval corresponding to the remaining fuel amount and determine an estimated weight corresponding to the fuel amount interval.

[0097] During the period when the target vehicle uploaded by the vehicle terminal or the user terminal arrives at the target service area through the cloud, the newly added vehicles to be recharged in each target service area are counted to obtain the remaining power or remaining fuel of each newly added vehicle to be recharged in the target service area, and the power range corresponding to each newly added vehicle to be recharged is determined according to the obtained remaining power, and then the corresponding estimated weight is determined according to the different divided power ranges, or the fuel amount range corresponding to each newly added vehicle to be recharged is determined according to the obtained remaining fuel, and then the corresponding estimated weight is determined according to the different divided fuel amount ranges.

[0098] The estimated weight is the weight obtained by weighting and summing each newly added vehicle to be recharged in each power interval or each fuel amount interval. The smaller the remaining power of the newly added vehicle to be recharged corresponding to the power interval, or the smaller the remaining fuel of the newly added vehicle to be recharged corresponding to the fuel amount interval, the greater the possibility of recharging in the target service area. Therefore, the weight of each newly added vehicle to be recharged corresponding to the power interval or the fuel amount interval is greater. For example, the weight of each newly added vehicle to be recharged in the power interval of (0, 25%] is 0.5, and the weight of each newly added vehicle to be recharged in the power interval of (50%, 75%] is 0.15.

[0099] S122: Determine an estimated index according to the estimated weight and the number of charging piles in the target service area.

[0100] The estimated weights corresponding to each power interval or each fuel interval are summed to obtain a total estimated weight, and the estimated index is determined based on the ratio between the estimated weight and the number of charging piles in the target service area. Each target service area obtains a corresponding estimated index. As the target vehicle travels toward the target service area A, the number of other vehicles in the target service area A that need to be charged gradually increases during the target vehicle's arrival at the target service area A. The remaining power or remaining fuel of the target vehicle will gradually decrease, and the possibility of the target vehicle charging in the target service area A will increase. At this time, the estimated charging queue time of the target vehicle in the target service area A indicated by the estimated index will also gradually increase with the increase in the number of other vehicles that need to be charged.

[0101] For example, when the target vehicle is still on the highway and is far away from multiple target service areas ahead, the estimated index of the target vehicle and each of the multiple target service areas ahead can be obtained, so that the user of the target vehicle can select the target service area for recharging the target vehicle. If the estimated index of a target service area A is larger, it means that the target vehicle has a longer estimated waiting time for recharging in the target service area A. After the estimated index is added to the recharging queue index of the target service area A, the recharging queue index is larger. If the estimated index of the target service area B is smaller, it means that the target vehicle has a shorter estimated waiting time for recharging in the target service area B. Similarly, after the estimated index is added to the recharging queue index, the recharging queue index is also smaller. Therefore, the target vehicle can preferably perform recharging service in the target service area B.

[0102] Exemplarily, the estimated index is calculated by combining the following experimental data of power range and estimated weight:

[0103] Table 3

[0104]

[0105] The power ranges corresponding to the remaining power of the newly added vehicles to be supplemented and the newly added vehicles to be supplemented are shown in Table 3, where the estimated weight corresponding to each newly added vehicle to be supplemented in the power range of (0, 25%] is 0.5, so the estimated weight corresponding to this power range is determined to be 1.5 (0.5*3); the estimated weight corresponding to each newly added vehicle to be supplemented in the power range of (25%, 50%] is 0.25, and the estimated weight corresponding to this power range is 1.5 (0.25*6); the power range of (50% The estimated weight corresponding to each newly added vehicle to be recharged in the power range [75%, 75%] is 0.15, and the estimated weight corresponding to this power range is 1.5 (0.15*10); the estimated weight corresponding to the power range [75%, 100%] is 0; and then the estimated weights corresponding to each power range are summed up to obtain a total estimated weight of 4.5; thus, the estimated index is determined according to the ratio between the total estimated weight and the number of charging piles, such as: the number of charging piles is 8, and the estimated index is (4.5 / 8) = 0.56.

[0106] In this way, the estimated index can be accurately obtained based on the estimated weight corresponding to the power range of the newly added vehicles to be recharged and the number of charging piles in the target service area, which further improves the accuracy of the charging queue index and enables users to make better charging decisions and improve driving efficiency.

[0107] In some embodiments of the present invention, reference Figure 6 , the vehicle energy replenishment method also includes:

[0108] S123: Obtain a historical index of each target service area, where the historical index is used to indicate a historical energy replenishment queue index of the target service area within a historical period of time.

[0109] It is understandable that when the travel date of the target vehicle is a holiday, there are more vehicles traveling on the highway. In order to obtain a more accurate energy replenishment queue index, the historical index is added as a reference index.

[0110] The historical index is obtained by obtaining the historical energy replenishment queue index corresponding to the target service area on the same travel date in previous years, and is obtained by multiplying the historical energy replenishment queue index and the estimated trend value. The historical index includes but is not limited to the historical energy replenishment queue index, the historical distance index, the historical congestion index, and the historical estimated index, which are parameters that constitute the historical energy replenishment queue index. The estimated trend value is set in advance according to the travel date. If the travel date of the target vehicle is a holiday, the estimated trend value is set to a larger value in consideration of the large number of vehicles traveling on the highway. If the travel date of the target vehicle is not a holiday, the estimated trend value is set to a smaller value in consideration of the small number of vehicles traveling on the highway.

[0111] For example, if the historical energy replenishment queue index is 6 and the estimated trend value is 0.1, then the historical index is 0.6 according to the product of the historical energy replenishment queue index and the estimated trend value.

[0112] S124: Determine a final refueling queue index of the target vehicle in each target service area according to at least one of a historical index, a refueling index, a distance index, a congestion index, and an estimated index.

[0113] That is to say, after determining the historical index and at least one of the energy replenishment index, distance index, congestion index and estimated index of the target service area, the indexes will be summed to obtain the final energy replenishment queue index of the target vehicle in each target service area, and the final energy replenishment queue index will be sent to the vehicle terminal display interface or the user terminal display interface, so that the user can comprehensively determine whether to recharge the target vehicle in the target service area based on the battery power of the vehicle.

[0114] Exemplarily, the travel date of the target vehicle is May 1st. Usually, May 1st is the first day of the May Day Labor Day. On this date, the traffic volume on the highway is usually large, and there are also many vehicles waiting to be recharged in the service area. Therefore, when determining the final recharge queue index of the target vehicle in each target service area, the historical recharge queue index of each target service area on the same travel date in previous years is obtained, and a larger estimated trend value is assigned to the historical recharge queue index. For example, the historical recharge queue index is 6, and the estimated trend value is 0.1. Then, according to the product of the historical recharge queue index and the estimated trend value, the historical index is 0.6, and then the historical index 0.6 is added to at least one of the recharge index, distance index, congestion index and estimated index of the corresponding target service area to obtain the final recharge queue index of each target service area, and each final recharge queue index is sent to the vehicle terminal display interface or the user terminal display interface, so that the user can comprehensively determine the target service area for recharging the target vehicle in combination with the battery power of the vehicle.

[0115] In this way, using the historical index as a reference index for the final energy replenishment queue index can efficiently determine the final energy replenishment queue index, allowing users to make better energy replenishment decisions and improve driving efficiency.

[0116] In the above embodiment, the final charging queue index of the target vehicle in each target service area is determined based on the acquired historical index and at least one of the charging index, distance index, congestion index and estimated index corresponding to the target vehicle, so as to reasonably estimate the charging queue conditions of multiple target service areas according to the final charging queue index, so that the user can select a suitable charging service area according to the charging queue index to improve the charging efficiency of the vehicle.

[0117] It should be noted that the specific numerical values ​​mentioned above are only used as examples to illustrate the implementation of the present invention in detail, and should not be understood as limiting the present invention. In other examples or implementations or embodiments, other numerical values ​​can be selected according to the present invention, and are not specifically limited here.

[0118] Corresponding to the above-mentioned embodiment, an embodiment of the present invention further provides a vehicle energy replenishment determination device.
