[0034] Figure 1 This is a flowchart of a vehicle charging reminder method according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0035] Step S12: Obtain vehicle driving data and charging history data of the target vehicle. The vehicle driving data is used to represent the target vehicle's cumulative driving mileage, remaining driving range and real-time location information, and the charging history data is used to represent the target vehicle's historical charging status and historical charging method.

[0036] In step S12 above, the cumulative mileage of the target vehicle refers to the mileage driven since the vehicle rolled off the production line, in km, denoted as OdometerValue. The remaining driving range of the target vehicle refers to the predicted driving range of the vehicle before the battery is completely depleted, in km, denoted as RemainingDriveDistance. The real-time location information of the target vehicle includes the longitude and latitude of the target vehicle's current location, in degrees-minutes-seconds, where longitude is denoted as Longitude and latitude as Latitude. The historical charging status of the target vehicle refers to whether the target vehicle is idle or charging, denoted as ChargeStatus. The historical charging method of the target vehicle refers to whether the target vehicle is charging with AC or DC power, denoted as ChargeState.

[0037] Step S14: Determine the target charging method and target charging factor based on vehicle driving data and charging history data. The target charging method is used to determine the recommended charging location for the target vehicle, and the target charging factor is used to determine the recommended charging time for the target vehicle.

[0038] In step S14 above, the target charging method includes, but is not limited to, AC charging and DC charging; the recommended charging location can be determined by selecting three charging stations or devices closest to the current location of the target vehicle; the target charging factor is used to determine the recommended charging time for the target vehicle, wherein the recommended charging time is determined personalized based on information such as the user's charging habits.

[0039] Step S16: Generate charging prompt information based on the target charging method and target charging factor;

[0040] In step S16 above, a recommended charging location is determined based on the target charging method, real-time location information, and electronic map information, and a charging prompt threshold is determined based on the target charging factor. Charging prompt information is generated based on the target charging method and the target charging factor. The electronic map information includes the location of the charging station or equipment and the corresponding charging method.

[0041] Step S18: Push the charging reminder information to the target vehicle to provide a charging reminder.

[0042] In step S18 above, the charging prompt information may include the target vehicle's charging prompt, the location information of the recommended charging station or equipment, and the charging method corresponding to the charging station or equipment, etc. The charging prompt information is pushed to the target vehicle's audio component and / or display component to provide charging prompts.

[0043] Based on steps S12 to S18 above, by acquiring the vehicle driving data and charging history data of the target vehicle, the target charging method and target charging factor are determined based on the vehicle driving data and charging history data. Then, charging prompt information is generated according to the target charging method and target charging factor. Finally, the charging prompt information is pushed to the target vehicle to provide charging reminders. This achieves the goal of making the judgment of vehicle charging prompts more suitable for the user's driving habits, thereby improving the flexibility, accuracy and user experience of vehicle charging prompts. This solves the technical problems of low flexibility and accuracy and poor user experience of vehicle charging prompts in related technologies.

[0044] Optionally, in step S14, determining the target charging method and target charging factor based on vehicle driving data and charging history data includes:

[0045] Step S141: Determine multiple historical charging segments based on historical charging data;

[0046] In step S141 above, the historical charging data is traversed, and the ChargeStatus signal data is used as the segmentation condition for historical charging segments to obtain all historical charging segments. Using the ChargeStatus signal data as the segmentation condition, based on the ChargeStatus signal data upload frequency, when ChargeStatus changes from "idle" to "charging," this is the start time of charging; when ChargeStatus changes from "charging" to "idle," this is the end time of charging. The period from the start time of charging to the end time of the first charging session is segmented into one charging segment.

[0047] Step S142: Count the DC charging frequency and AC charging frequency of the target vehicle in multiple historical charging segments;

[0048] In step S142 above, DC charging frequency refers to the frequency of ChargeState being DC charging in all historical charging segments, denoted as DC_Frequency, and AC charging frequency refers to the frequency of ChargeState being AC charging in all historical charging segments, denoted as AC_Frequency.

[0049] Step S143: Determine the AC charging ratio and DC charging ratio based on the DC charging frequency and AC charging frequency;

[0050] In step S143 above, the AC charging ratio is denoted as AC_per, and the formula for calculating AC_per is shown in equation (1). The DC charging ratio is denoted as DC_per, and the formula for calculating DC_per is shown in equation (2).

[0051]

[0052]

[0053] Step S144: Determine the target charging method using the AC charging ratio and the DC charging ratio.

[0054] In step S144 above, the target charging method can be determined by the AC ratio and DC ratio, wherein the target charging method includes, but is not limited to, AC charging method and DC charging method.

[0055] Based on steps S141 to S144 above, firstly, multiple historical charging segments are determined according to historical charging data. Then, the AC_Frequency and DC_Frequency of the target vehicle in these segments are statistically analyzed. Next, AC_per and DC_per are calculated based on AC_Frequency and DC_Frequency. Finally, the target charging method is determined using AC_per and DC_per. By analyzing vehicle driving data and historical charging data to determine the target charging method, suitable charging stations or equipment can be recommended to the target vehicle user, thereby improving the accuracy of vehicle charging prompts and the user experience.

[0056] Optionally, in step S144, determining the target charging method using the AC charging ratio and the DC charging ratio includes:

[0057] Step S1441: In response to the first difference between the AC charging ratio and the DC charging ratio being greater than a preset value, the target charging method is determined to be AC ​​charging method.

[0058] Step S1442: In response to the second difference between the DC charging ratio and the AC charging ratio being greater than a preset value, the target charging mode is determined to be DC charging mode.

[0059] In steps S1441 to S1442 above, the first difference refers to the value of AC_per - DC_per, and the second difference refers to the value of DC_per - AC_per. If the value of AC_per - DC_per is greater than a preset value, the target charging method is AC charging; if the value of DC_per - AC_per is greater than a preset value, the target charging method is DC charging. Specifically, Figure 2 This is a schematic diagram illustrating the determination of a target charging method according to one embodiment of the present invention, as shown below. Figure 2As shown, the target charging method is determined based on vehicle driving data and charging history data. First, the onboard terminal collects the real-time location information and charging history data of the target vehicle, and obtains charging station or equipment information from electronic map information. Then, the collected data is uploaded to the data processing platform. Based on the charging history data, multiple historical charging segments are determined, and the AC_Frequency and DC_Frequency of the target vehicle in multiple historical charging segments are calculated. Based on AC_Frequency and DC_Frequency, AC_per and DC_per are calculated. Finally, the target charging method is determined using AC_per and DC_per.

[0060] Furthermore, if the first difference between AC_per and DC_per is greater than 80%, the target charging method is determined to be AC ​​charging; if the second difference between DC_per and AC_per is greater than 80%, the target charging method is determined to be DC charging.

[0061] Finally, determine the charging recommendation location according to the user's sensitivity to the charging method. Among them, if AC_per - DC_per ≥ 80%, it indicates that the user of the target vehicle highly prefers the AC charging method or the target vehicle does not have the DC charging ability. According to the real-time position information of the target vehicle and the electronic map information, calculate the 3 AC charging stations or devices closest to the current position of the target vehicle. The distances of the target vehicle from the 3 AC charging stations or devices are recorded as Distance1, Distance2, and Distance3 from near to far, that is, Distance1 < Distance2 < Distance3; if DC_per - AC_per ≥ 80%, it indicates that the user of the target vehicle highly prefers the DC charging method or the target vehicle does not have the AC charging ability. According to the real-time position information of the target vehicle and the electronic map information, calculate the 3 DC charging stations or devices closest to the current position of the target vehicle. The distances of the target vehicle from the 3 DC charging stations or devices are recorded as Distance1, Distance2, and Distance3 from near to far, that is, Distance1 < Distance2 < Distance3; if the difference between AC_per and DC_per satisfies AC_per - DC_per < 80% or the difference between DC_per and AC_per satisfies DC_per - AC_per < 80%, it is considered that the user of the target vehicle is not sensitive to the charging method. According to the real-time position information of the target vehicle and the electronic map information, calculate the 3 charging stations or devices closest to the current position of the target vehicle. The distances of the target vehicle from the 3 charging stations or devices are recorded as Distance1, Distance2, and Distance3 from near to far, that is, Distance1 < Distance2 < Distance3.

[0062] Based on the above steps S141 to S1442, first determine multiple historical charging segments according to the charging history data, count the AC_Frequency and DC_Frequency of the target vehicle in the multiple historical charging segments, then calculate AC_per and DC_per, and then use AC_per and DpeC_per to determine the target charging method. Finally, determine the charging recommendation location based on the target charging method, the real-time position information of the target vehicle, and the electronic map information. By analyzing the vehicle driving data and charging history data to determine the target charging method, and then combining the real-time position information of the target vehicle and the electronic map information to determine the charging recommendation location, it is possible to recommend suitable charging stations or devices for the users of the target vehicle, thereby improving the accuracy of vehicle charging prompts and the user experience.

[0063] Optionally, in step S14, determining the target charging method and the target charging factor based on the vehicle driving data and the charging history data further includes:

[0064] Step S145: Obtain the range difference information and the cumulative range difference information. The range difference information is used to represent the remaining range added between the first time and the second time, and the cumulative range difference information is used to represent the cumulative driving mileage added between the second time and the third time. The first time is the charging start time corresponding to the first charging segment, the second time is the charging end time corresponding to the first charging segment, and the third time is the charging start time corresponding to the second charging segment. The first charging segment and the second charging segment are adjacent charging segments among multiple historical charging segments.

[0065] In step S145 above, the remaining driving range at the start of charging in the first charging segment of the target vehicle is recorded and denoted as Start_RemainingDriveDistance. (n) Record the remaining driving range at the end of the first charging segment of the target vehicle, denoted as End_RemainingDriveDistance. (n) The range difference information is the additional remaining range added between the start and end times of the first charging segment, denoted as add_RemainingDriveDistance. (n) The calculation formula is shown in equation (3); the cumulative mileage at the end of the first charging segment of the target vehicle is recorded and denoted as End_OdometerValue. (n) Record the cumulative mileage driven at the start of charging during the second charging segment of the target vehicle, denoted as Start_OdometerValue. (n-1) The cumulative mileage difference information is the additional cumulative mileage traveled between the end time of the first charging segment and the start time of the second charging segment, denoted as interval_last_mileage. (n) The calculation formula is shown in equation (4).

[0066] add_RemainingDriveDistance (n) =

[0067] End_RemainingDriveDistance (n) -Start_RemainingDriveDistance (n) (3)

[0068] interval_last_mileage (n) =Start_OdometerValue (n) -End_OdometerValue(n-1) (4)

[0069] Step S146: Determine the predicted charging factor corresponding to the second charging segment based on the driving range difference information and the cumulative mileage difference information;

[0070] In step S146 above, the predicted charging factor corresponding to the second charging segment is determined based on the driving range difference information and the cumulative mileage difference information. The predicted charging factor represents the user's judgment of the recommended charging time for the target vehicle and is denoted as Charging_personality. The predicted charging factor for the nth historical charging segment is Charging_personality. (n) The calculation formula is shown in equation (5):

[0071]

[0072] Where Charging_personality∈(0,1), the closer Charging_personality is to 1, the more aggressive the user of the target vehicle is, and the more aggressive they will be ...

[0073] Step S147: Determine the target charging factor based on multiple predicted charging factors corresponding to multiple historical charging segments.

[0074] In step S147 above, the target charging factor refers to the 75th percentile of the predicted charging factor of the most recent 50 historical charging segments, denoted as Charging_personality_75, where Charging_personality_75∈(0,1).

[0075] Specifically, firstly, the predicted charging factors of the most recent 50 historical charging segments are sorted in ascending order. The Charing_personality_75 value of the 50 historical charging segments is obtained by using Charing_personality (37) and Charing_personality (38) The Charing_personality_75 value is calculated using the formula shown in equation (6) for these 50 historical charging segments:

[0076] Charing_personality_75= Charing_personality (37)*75%+Charing_personality (38) *25% (6)

[0077] Based on steps S145 to S147 above, the following steps are first taken: the driving range difference information and the cumulative mileage difference information are obtained. A new data field is defined, and the driving range difference and cumulative mileage difference are calculated based on this new data field. Then, the predicted charging factor corresponding to the second charging segment is determined based on the driving range difference information and the cumulative mileage difference information. Finally, the target charging factor is determined based on multiple predicted charging factors corresponding to multiple historical charging segments. By analyzing vehicle driving data and charging history data to determine the target charging factor and recommended charging timing, a suitable recommended charging time can be selected for the user of the target vehicle. This makes the determination of the recommended charging time more suitable for the user's driving habits, thereby improving the user's product experience.

[0078] Optionally, in step S16, generating charging prompt information based on the target charging method and target charging factor includes:

[0079] Step S161: Determine the recommended charging location based on the target charging method, real-time location information and electronic map information, and determine the charging prompt threshold based on the target charging factor;

[0080] Step S162: In response to the change in the remaining driving range of the target vehicle to the charging reminder threshold, a charging reminder message is generated using the recommended charging location.

[0081] Specifically, during the driving process of the target vehicle, based on the real-time position information of the target vehicle and the electronic map information, calculate the 3 charging stations or devices closest to the current position of the target vehicle. The distances of the target vehicle from the 3 charging stations or devices are recorded as Distance1, Distance2, and Distance3 from near to far, that is, Distance1 < Distance2 < Distance3. When the ratio of Distance3 to the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, as shown in Equation (7), the in-vehicle voice prompts "The remaining driving range is insufficient. Please replenish energy in time"; when the ratio of Distance2 to the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, as shown in Equation (8), the in-vehicle voice prompts "The remaining driving range is insufficient. Please replenish energy in time", the instrument panel displays "The remaining driving range is insufficient. Please replenish energy in time", and the in-vehicle system pops up the two charging stations or devices with the shortest distances, that is, the charging stations or devices corresponding to Distance1 and Distance2; when the ratio of Distance1 to the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, as shown in (9), the instrument displays "The remaining driving range is insufficient. Please replenish energy in time", the instrument panel displays "The remaining driving range is insufficient. Please replenish energy in time", the in-vehicle system pops up the two charging stations or devices with the shortest distances, that is, the charging stations or devices corresponding to Distance1 and Distance2, and the non-driving functions in the vehicle are turned off, and the in-vehicle prompts "The low battery mode has been entered. Please manually turn on the remaining non-driving necessary functions".

[0082]

[0083]

[0084]

[0085] Based on the above steps S161 to S162, determine the charging recommended location based on the target charging method, real-time position information and electronic map information, determine the charging prompt threshold based on the target charging factor, and generate the charging prompt information using the charging recommended location. By setting different charging thresholds to push charging reminders, the technical problem of low flexibility and poor user experience of vehicle charging prompts caused by relying on a fixed low battery prompt value for vehicle charging prompts is solved. At the same time, by continuously online correcting the charging prompt threshold by real-time monitoring of vehicle driving data and charging history data, the accuracy of vehicle charging prompts is improved.

[0086] Optionally, in step S18, pushing the charging prompt information to the target vehicle for charging prompt includes:

[0087] Step S181: Push charging reminder information to the audio component and / or display component of the target vehicle to provide a charging reminder.

[0088] In step S182, in response to the remaining driving range of the target vehicle changing to the charging reminder threshold, the non-driving functions of the target vehicle are turned off, and vehicle function reminder information is pushed to the target vehicle.

[0089] Specifically, the audio component can be a speaker to play charging reminder information, and the display component can be a display screen or other device with a display. A display command is sent to the display component to display the charging reminder information. When the remaining range of the target vehicle changes to the charging reminder threshold, the non-driving functions of the target vehicle are turned off, and a vehicle function reminder message is pushed to the target vehicle. The vehicle system prompts "Low battery mode has been entered. Please manually turn on other non-driving necessary functions."

[0090] Based on steps S181 to S182 above, charging reminder information is pushed to the audio component and / or display component of the target vehicle to provide a charging reminder. When the remaining range of the target vehicle changes to the charging reminder threshold, the non-driving functions of the target vehicle are turned off, and a vehicle function reminder message is pushed to the target vehicle. By turning off the non-driving functions in the vehicle and displaying the message "Low battery mode has been entered. Please manually turn on other non-driving necessary functions," a longer margin of error is provided for the user to ensure that the user can reach the charging location before the battery is depleted, thereby avoiding the dangerous situation of the vehicle being forced to stop due to the battery being depleted.

[0091] Figure 3 This is a schematic diagram of another vehicle charging reminder method according to one embodiment of the present invention. As shown in the figure, the vehicle charging reminder method mainly includes the following execution steps:

[0092] Step S301: Collect vehicle driving data and charging history data of the target vehicle;

[0093] Step S302: Upload the data to the data processing platform;

[0094] Step S303: Divide the charging history data into multiple historical charging segments;

[0095] Step S304: Determine the target charging method and target charging factor based on vehicle driving data and charging history data;

[0096] Step S305: Determine the recommended charging location based on the target charging method, real-time location information and electronic map information, and determine the charging prompt threshold based on the target charging factor;

[0097] Step S306: When the remaining driving range of the target vehicle changes to the charging reminder threshold, a charging reminder message is generated using the recommended charging location.

[0098] Step S307: Push the charging reminder information to the audio component and / or display component of the target vehicle to provide a charging reminder.

[0099] In the aforementioned vehicle charging reminder method, the vehicle driving data and charging history data of the target vehicle are obtained. Then, the target charging method and target charging factor are determined based on the vehicle driving data and charging history data. Subsequently, charging reminder information is generated according to the target charging method and target charging factor. Finally, the charging reminder information is pushed to the target vehicle to provide charging reminders. This achieves the goal of making vehicle charging reminders more suitable for users' driving habits, thereby improving the flexibility, accuracy, and user experience of vehicle charging reminders. This solves the technical problems of low flexibility and accuracy and poor user experience in related technologies.

[0100] The following example will provide a detailed explanation of the workflow of the vehicle charging reminder method described above:

[0101] Assuming vehicle driving data and charging history data have been obtained from the target vehicle's terminal, the charging history data is first segmented into 15 historical charging segments. These 15 segments are used here to illustrate the 50 historical charging segments defined above. Within these 15 segments, AC_per, DC_per, and the first difference are calculated. Where AC_per equals 92% and DC_per equals 8%, then AC_per - DC_per = 84%, meaning AC_per - DC_per ≥ 80%, indicating that the target vehicle's user strongly prefers AC charging or that the target vehicle lacks DC charging capability. Then, combining the target vehicle's real-time location information and electronic map information, the three closest AC charging stations or devices are calculated in real-time. The distances from the target vehicle to these three charging stations or devices, from closest to furthest, are denoted as Distance1, Distance2, and Distance3, respectively. <Distance2<Distance3。

[0102] Furthermore, the system acquires the driving range difference information and the cumulative mileage difference information, and then determines the predicted charging factor corresponding to the second charging segment based on these information. The predicted charging factor represents the user's judgment of the recommended charging time for the target vehicle. Based on vehicle driving data and charging history data, interval_last_mileage, add_RemainingDriveDistance, and Charing_personality are calculated, as shown in Table 1, which displays the driving range difference information, cumulative mileage difference information, and predicted charging factor for the target vehicle.

[0103] Table 1

[0104]

[0105] The target charging factor is calculated from Table 1, where the target charging factor refers to the 75th percentile of the Charing_personality of the most recent 50 historical charging segments. Since 15 historical charging segments are used here to illustrate the 50 historical charging segments defined above, the 75th percentile of the 15 historical charging segments in Table 1 is calculated. As can be seen from the data in Table 1, there are a total of 15 Charing_personality values. These 15 Charing_personality values ​​are arranged in ascending order. The Charing_personality_75 value of the 15 historical charging segments is calculated using the Charing_personality values ​​corresponding to the 11th and 12th historical charging segments. Therefore, the formula for calculating the Charing_personality_75 value of the above 15 historical charging segments is shown in Equation (10).

[0106] Charing_personality_75=Charing_personality (11) *75%+Charing_personality (12) *25% (10)

[0107] From Table 1, we can obtain Charing_personality (11) =81.95%、Charing_personality (12) =83.33%, and Charing_personality_75 = 0.82295 is calculated from equation (10).

[0108] Finally, determine the charging recommended location based on the target charging method, real-time location information, and electronic map information, determine the charging prompt threshold based on the target charging factor. When the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, generate the charging prompt information using the charging recommended location, and push the charging prompt information to the audio component and / or display component of the target vehicle for charging prompt. During the driving process of the target vehicle, calculate the 3 charging stations or devices closest to the current position of the target vehicle according to the real-time location information of the target vehicle and the electronic map information. The distances of the target vehicle from the 3 charging stations or devices are recorded as Distance1, Distance2, and Distance3 from near to far, that is, Distance1 < Distance2 < Distance3. When the ratio of Distance3 to the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, as shown in Equation (7), the in-vehicle voice prompts "The remaining driving range is insufficient, please replenish energy in time", where Charing_personality_75 = 0.82295; when the ratio of Distance2 to the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, as shown in Equation (8), the in-vehicle voice prompts "The remaining driving range is insufficient, please replenish energy in time", the dashboard displays "The remaining driving range is insufficient, please replenish energy in time", and the in-vehicle system pops up the two charging stations or devices with the shortest distances, that is, the charging stations or devices corresponding to Distance1 and Distance2, where Charing_personality_75 = 0.82295; when the ratio of Distance1 to the RemainingDriveDistance of the target vehicle changes to the charging prompt threshold, as shown in Equation (9), the instrument display shows "The remaining driving range is insufficient, please replenish energy in time", the dashboard displays "The remaining driving range is insufficient, please replenish energy in time", the in-vehicle system pops up the two charging stations or devices with the shortest distances, that is, the charging stations or devices corresponding to Distance1 and Distance2, the non-driving functions in the vehicle are turned off, and the in-vehicle prompt is "The low battery mode has been entered, please manually turn on the remaining non-driving necessary functions", where Charing_personality_75 = 0.82295.

[0109] Based on steps S31 to S37 above, by acquiring the vehicle driving data and charging history data of the target vehicle, the target charging method and target charging factor are determined based on the vehicle driving data and charging history data. Then, charging prompt information is generated according to the target charging method and target charging factor. Finally, the charging prompt information is pushed to the target vehicle to provide charging reminders. This achieves the goal of making the judgment of vehicle charging prompts more suitable for the user's driving habits, thereby improving the flexibility, accuracy and user experience of vehicle charging prompts. This solves the technical problems of low flexibility and accuracy and poor user experience of vehicle charging prompts in related technologies.
