[0003] However, the manual adjustment of the PHEV driving mode according to the requirements of the driver does not consider the SOC balance of the vehicle-mounted battery during the driving distance, so that the feeding amount of the vehicle-mounted battery is high, and the energy consumption of the vehicle during driving is unreasonable, thereby affecting the service life of the battery. SUMMARY

[0045] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of vehicle inspection technology.

[0046] Currently, the method of manually adjusting the driving mode of PHEV vehicles according to the driver's needs does not take into account the SOC balance of the vehicle battery during the driving journey. As a result, the battery depletion rate is relatively high, which leads to unreasonable energy consumption during driving and affects the battery's lifespan.

[0047] Based on this, the embodiment of the present application provides a vehicle SOC balance point adjustment method, device and storage medium. The embodiment of the present application solves the technical problem that the power feeding amount of the vehicle is high, and the energy consumption of the vehicle is large during driving in the prior art. Compared with the mode of selecting driving according to user demand, the embodiment of the present application adjusts the vehicle SOC balance point based on the navigation distance and the remaining power of the vehicle-mounted battery, which can reduce the power feeding amount and energy consumption in different driving modes, thereby prolonging the service life of the vehicle-mounted battery.

[0048] Figure 1 A flowchart of a vehicle SOC balance point adjustment method provided by the embodiment of the present application is shown in Figure 1 The vehicle SOC balance point adjustment method is applied to a battery management module. The vehicle SOC balance point adjustment method comprises the following steps:

[0049] S101, in the case that the vehicle-mounted terminal is in a navigation mode, obtaining the remaining power of the vehicle-mounted battery, the vehicle's range under the remaining power, and the untravelled distance of the journey from the navigation starting point to the navigation target point.

[0050] In this step, the embodiment provided by the present application is controlled by the battery management module (Battery Management System, BMS). After the vehicle starts the navigation mode, the BMS sets the navigation distance from the navigation starting point to the navigation target point, and obtains the remaining power of the vehicle-mounted battery, the vehicle's range under the remaining power, and the untravelled distance of the journey from the navigation starting point to the navigation target point in real time.

[0051] It can be understood that the embodiment provided by the present application also obtains the pure electric range of the vehicle-mounted battery under the full power state, and determines whether the vehicle can enable the pure electric range mode in the untravelled distance of the journey according to the size relationship between the pure electric range and the untravelled distance of the journey.

[0052] Wherein, it is assumed that the untravelled distance of the journey in the embodiment provided by the present application is represented by Length_R; the pure electric range is represented by Length_C; the remaining power of the vehicle-mounted battery is represented by BMS_SOC; and the vehicle's range under the remaining power is represented by Length_C1.

[0053] S102, determining the preset SOC balance point of the vehicle-mounted battery under the untravelled distance of the journey based on the distance of the journey.

[0054] In this step, the embodiments provided in this application determine the engine start-stop SOC threshold corresponding to each working condition according to the driving habits of the user after determining the distance of the untraveled journey from the navigation starting point to the navigation target point in the navigation mode, and thus determine the preset SOC balance point of the vehicle-mounted battery under different lengths of untraveled journey distance.

[0055] In the above, when the vehicle needs to determine whether the motion state of the vehicle under the journey distance is the motion mode, if it is determined that the motion state of the vehicle under the journey distance is the motion mode, the preset SOC balance point corresponding to the motion mode is determined to be the high-power S_SOC.

[0056] It can be understood that the embodiments provided in this application will determine different preset SOC balance points according to different untraveled journey distances, specifically but not limited to:

[0057] When Length_R≥100km, the corresponding preset SOC balance point is determined to be the medium-power H_SOC; when Length_R<100km, the corresponding preset SOC balance point is determined to be the low-power L_SOC, and in order to avoid the occurrence of situations such as overcharging, overdischarging and insufficient kinetic energy recovery capacity of the vehicle-mounted battery at the vehicle end, the embodiments provided in this application will manually select the value of the preset SOC balance point under each working condition to be between 20% and 80%.

[0058] The state of charge (SOC) balance point refers to the ideal power level of the battery, which refers to the percentage of battery power that the vehicle hopes to maintain during operation, and reasonable setting and management of the SOC balance point is crucial for optimizing vehicle performance, fuel economy and battery life.

[0059] S103, according to the journey distance, the preset remaining journey distance, the remaining power of the vehicle-mounted battery and the range under the remaining power, performing an operation to make the remaining power of the vehicle-mounted battery reach the preset SOC balance point.

[0060] In this step, after determining the preset SOC balance point corresponding to different journey distances, the embodiments provided in this application begin to dynamically adjust the SOC balance point of the vehicle-mounted battery according to the journey distance, the preset remaining journey distance, the remaining power of the vehicle-mounted battery and the range under the remaining power collected in real time during the driving process of the vehicle, so that the remaining power of the vehicle-mounted battery reaches the preset SOC balance point, achieving the purpose of energy saving.

[0061] It can be understood that the SOC balance point of the vehicle-mounted battery in the embodiments provided in the present application can be customized and selected according to different application scenarios. It is assumed that the SOC balance point of the vehicle-mounted battery in the embodiments provided in the present application can be specifically but not limited to charging the vehicle-mounted battery by controlling the engine start-stop SOC threshold.

[0062] For example, based on the travel distance, the preset remaining travel distance, the remaining power of the vehicle-mounted battery, and the range under the remaining power, the operation of making the remaining power of the vehicle-mounted battery reach the preset SOC balance point is performed, including:

[0063] When the vehicle starts driving and the remaining travel distance of the vehicle to the navigation target is greater than or equal to the preset remaining travel distance, the engine of the vehicle is controlled to charge the vehicle-mounted battery based on the remaining power of the vehicle-mounted battery, the travel distance, and the range under the remaining power, and the remaining power of the vehicle-mounted battery is controlled to reach the preset SOC balance point.

[0064] It should be noted that during the process of the vehicle starting driving, the remaining travel distance of the vehicle to the navigation target is monitored in real time, which is represented by Length_R1.

[0065] In the above, when the vehicle starts driving and the remaining travel distance of the vehicle to the navigation target is greater than or equal to the preset remaining travel distance, the engine of the vehicle is controlled to charge the vehicle-mounted battery based on the remaining power of the vehicle-mounted battery, the travel distance, and the range under the remaining power, and the remaining power of the vehicle-mounted battery is controlled to reach the preset SOC balance point, including the following sub-steps:

[0066] Sub-step 1, if the driving mode of the vehicle is a pure electric driving mode, when the vehicle starts driving and the remaining travel distance of the vehicle to the navigation target is greater than or equal to the preset remaining travel distance, it is determined whether the vehicle meets the preset pure electric driving condition based on the remaining travel distance of the vehicle during driving and the range under the remaining power.

[0067] In the above, it is necessary to determine the driving mode of the vehicle first. The embodiments provided in the present application compare the travel distance Length_R and the pure electric range Length_C to determine the driving mode of the vehicle. When Length_C is greater than Length_R, it is determined that the driving mode of the vehicle is a pure electric driving mode. When Length_C is less than Length_R, it is determined that the driving mode of the vehicle is a non-pure electric driving mode.

[0068] It can be understood that, assuming that the stroke distance Length_R in the embodiments provided in the present application includes two kinds of long stroke distance and short long stroke distance, wherein the long stroke distance is specifically: Length_R≥100km, at this time if Length_C≥125km, it is determined that the driving mode of the vehicle is pure electric driving mode; the stroke distance is specifically: Length_R<100km, if Length_C≥100km, it is determined that the driving mode of the vehicle is pure electric driving mode.

[0069] For example, when the driving mode of the vehicle is pure electric driving mode, the vehicle starts driving, and the remaining stroke distance of the vehicle to the navigation target is greater than or equal to the preset remaining stroke distance, it is determined whether the vehicle satisfies the preset pure electric driving condition based on the remaining stroke distance and the remaining electric quantity under the vehicle in the driving process. The remaining stroke distance and the remaining electric quantity under the vehicle in the driving process.

[0070] Here, when it is determined that the driving mode of the vehicle is pure electric driving mode, the vehicle starts driving, and Length_R1 is greater than or equal to the preset remaining stroke distance, it is determined that the remaining electric quantity under the remaining stroke distance is greater than the preset remaining electric quantity threshold, and the preset percentage of the remaining electric quantity under the remaining stroke distance is greater than the remaining stroke distance. If yes, it is determined that the vehicle satisfies the preset pure electric driving condition; if no, it is determined that the vehicle does not satisfy the preset pure electric driving condition.

[0071] Among them, the preset remaining electric quantity threshold can be selected according to different application scenarios, assuming that the remaining electric quantity threshold in the embodiments provided in the present application is specifically 65km.

[0072] Substep 2, if not satisfied, send a charging request for charging the vehicle battery to the vehicle terminal.

[0073] In the above, if the vehicle does not satisfy the preset pure electric driving condition, the nearest charging station is recommended for charging to the vehicle terminal, and a charging request for charging the vehicle battery is sent to the vehicle terminal.

[0074] Substep 3, if the charging authorization request determined based on the charging request is received, output the prompt information that the vehicle battery needs to be charged at the location of the vehicle.

[0075] In the above, when the user operates the vehicle terminal to determine to accept the charging request, the vehicle terminal receives the charging authorization request determined based on the charging request, at this time, the prompt information that the vehicle battery needs to be charged at the location of the vehicle is output, wherein the prompt information here is specifically but not limited to the position information of the nearby charging station.

[0076] Sub-step 4, if the charging authorization request is not received, when the remaining power of the vehicle-mounted battery is less than the preset SOC balance point, the engine in the vehicle is controlled to drive the generator to start charging the vehicle-mounted battery, or when the vehicle speed is greater than or equal to the preset vehicle speed threshold, the engine of the vehicle is directly controlled to drive the vehicle.

[0077] It should be noted that if the user operates the vehicle-mounted terminal to determine to accept the charging request, at this time the vehicle-mounted terminal does not receive the charging authorization request determined based on the charging request, at this time, when the remaining power of the vehicle-mounted battery is less than the preset SOC balance point (i.e. BMS_SOC

[0078] In the embodiments provided in the present application, the preset vehicle speed threshold can be selected and used according to different application scenarios, and the preset vehicle speed threshold in the embodiments provided in the present application can be specifically but not limited to 80km / h.

[0079] Sub-step 5, when the remaining power of the vehicle-mounted battery is greater than or equal to the preset SOC balance point, or the difference between the remaining power and the distance of the remaining power is greater than the preset distance, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle-mounted battery, and the remaining power of the vehicle-mounted battery is controlled to reach the preset SOC balance point.

[0080] It should be noted that when BMS_SOC≥H_SOC or Length_C1-Length_R1≥the preset distance, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle-mounted battery, and the remaining power of the vehicle-mounted battery is controlled to reach the preset SOC balance point.

[0081] In the embodiments provided in the present application, the preset distance can be selected and used according to different application scenarios, and the preset distance in the embodiments provided in the present application can be specifically but not limited to 50km.

[0082] For example, when the remaining distance of the vehicle to the navigation target is less than the preset remaining distance, and the power difference between the remaining power of the vehicle and the preset SOC balance point is less than the preset power difference, or the remaining power is less than the pure electric endurance mileage, the prompt information that the vehicle needs to be charged at the navigation target is output, wherein the pure electric endurance mileage represents the endurance mileage of the vehicle in the pure electric driving mode.

[0083] It should be noted that in the process of starting the vehicle to travel, the remaining distance of the vehicle to the navigation target is monitored in real time, which is represented by Length_R1. When BMS_SOC-H_SOC is less than or equal to the preset power difference, or Length_C1≥Length_C, the prompt information that the vehicle needs to be charged at the navigation target is output.

[0084] In the embodiments provided in the present application, the preset power difference can be selected and used according to different application scenarios. For example, the preset power difference in the embodiments provided in the present application can be specifically but not limited to 10% H_SOC.

[0085] For example, if the driving mode of the vehicle is pure electric driving mode, when the vehicle starts to travel and the remaining distance of the vehicle to the navigation target is greater than or equal to the preset remaining distance, whether the vehicle meets the preset pure electric driving condition is determined based on the remaining distance and the remaining power of the vehicle during travel. The determination includes the following sub-steps:

[0086] Sub-step 1: If the driving mode of the vehicle is pure electric driving mode, when the vehicle starts to travel and the remaining distance of the vehicle to the navigation target is greater than or equal to the preset remaining distance, whether the vehicle is in motion mode is determined based on the acceleration driving time of the vehicle within the preset driving time.

[0087] It should be noted that if Length_C is greater than Length_R, it is determined that the driving mode of the vehicle is pure electric driving mode, when the vehicle starts to travel and the remaining distance of the vehicle to the navigation target is greater than or equal to the preset remaining distance, the acceleration driving time of the vehicle within the preset driving time is greater than the first preset acceleration driving time, it is determined that the vehicle is in motion mode; and the acceleration driving time of the vehicle within the preset driving time is less than the second preset acceleration driving time, it is determined that the vehicle is not in motion mode.

[0088] In the above, the embodiments provided in the present application accelerate the vehicle by the accelerator pedal opening degree, and determine the acceleration driving time by the cumulative time of the accelerator pedal opening degree≥70%.

[0089] Here, the first preset acceleration driving time and the second preset acceleration driving time in the embodiments provided in the present application can be selected and used according to different application scenarios. For example, the first preset acceleration driving time in the embodiments provided in the present application can be specifically but not limited to 30s; the second preset acceleration driving time can be specifically but not limited to 15s.

[0090] Sub-step 2, if the vehicle is not in the motion mode, when the remaining battery life is greater than the preset remaining battery life threshold and the preset percentage of the remaining battery life is greater than the remaining distance, it is determined that the vehicle meets the preset pure electric driving condition.

[0091] It should be noted that in the embodiments provided in the present application, if Length_C1 is greater than the preset remaining battery life threshold and Length_C1*80% is greater than Length_R1, it is determined that the vehicle meets the preset pure electric driving condition.

[0092] In the embodiments provided in the present application, the preset remaining battery life threshold can be specifically but not limited to 65km.

[0093] Sub-step 3, when the remaining battery life is less than or equal to the preset remaining battery life threshold and the preset percentage of the remaining battery life is less than or equal to the remaining distance, it is determined that the vehicle does not meet the preset pure electric driving condition.

[0094] It should be noted that if Length_C1 is less than or equal to 65km and Length_C1*80% is less than or equal to Length_R1, it is determined that the vehicle does not meet the preset pure electric driving condition.

[0095] For example, if the driving mode of the vehicle is a non-pure electric driving mode, when the vehicle starts driving and the remaining distance of the vehicle to the navigation target is greater than or equal to the preset remaining distance, when the remaining battery of the vehicle is less than the preset SOC balance point, the engine in the vehicle is controlled to drive the generator to start charging the vehicle battery; when the remaining battery is greater than or equal to the preset SOC balance point, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle battery; or when the difference between the remaining battery life and the distance is greater than the preset distance, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle battery, and the remaining battery of the vehicle is controlled to reach the preset SOC balance point.

[0096] It should be noted that if the driving mode of the vehicle is a non-pure electric driving mode, when the vehicle starts driving and Length_R1 is greater than or equal to 1km, when BMS_SOC is less than H_SOC, the engine in the vehicle is controlled to drive the generator to start charging the vehicle battery; when BMS_SOC is greater than or equal to H_SOC, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle battery, or when Length_C1-Length_R is greater than 50km, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle battery, and the remaining battery of the vehicle is controlled to reach the preset SOC balance point.

[0097] The following is illustrated with specific embodiments:

[0098] Example One:

[0099] Sub-step 1, assuming Length_R≥100km.

[0100] Sub-step 2, at this time, if Length_C≥125km, at this time, the pure electric drive mode is preferred to be used; if Length_C<125km, under the condition of BMS_SOC<H_SOC, the engine is started.

[0101] Then, under the condition of Length_C1-Length_R1≥50km or BMS_SOC≥H_SOC, the engine is stopped.

[0102] Sub-step 2, when the vehicle starts to run, if Length_C1≤65km and Length_C1*70%≤Length_R1, at this time, the vehicle terminal sends a charging request, if the user agrees to the charging request, the vehicle terminal still sends a charging request when Length_C1≤65km and Length_C1*70%≤Length_R1 is met again, if the user disagrees to the charging request, the engine is started when the vehicle speed≥80km / h or BMS_SOC<H_SOC is detected.

[0103] Sub-step 3, after the engine is started, real-time monitoring is performed, and the engine is stopped when Length_C1-Length_R1≥50km or BMS_SOC≥H_SOC.

[0104] Example Two:

[0105] Sub-step 1, assuming Length_R<100km.

[0111] Figure 2 The structure block diagram of a vehicle SOC balance point adjustment device provided by the embodiments of the present application is shown in FIG. 2. Figure 2 As shown in FIG. 2, the vehicle SOC balance point adjustment device 200 comprises:

[0112] The acquisition module 210 is configured to acquire the remaining electric quantity of the vehicle battery, the distance that can be traveled under the remaining electric quantity of the vehicle and the untraveled distance from the navigation starting point to the navigation target point when the vehicle terminal is in the navigation mode.

[0113] The determination module 220 is configured to determine the preset SOC balance point of the vehicle battery under the untraveled distance based on the distance.

[0114] The execution module 230 is configured to perform the operation of making the remaining electric quantity of the vehicle battery reach the preset SOC balance point according to the distance, the preset remaining distance, the remaining electric quantity of the vehicle battery and the distance that can be traveled under the remaining electric quantity.

[0115] Specifically, the execution module 230 is configured to:

[0116] When the vehicle starts driving and a remaining distance of the vehicle to the navigation target location is greater than or equal to a preset remaining distance, the engine of the vehicle is controlled to charge the vehicle battery based on a remaining amount of the vehicle battery, a distance and a range of the vehicle in the remaining amount of the vehicle battery, and the remaining amount of the vehicle battery is controlled to reach a preset SOC balance point.

[0117] The execution module 230 is further configured to:

[0118] When the remaining distance of the vehicle to the navigation target location is less than the preset remaining distance, and a difference between the remaining amount of the vehicle and the preset SOC balance point is less than a preset amount of electricity, or the range of the vehicle in the remaining amount of the vehicle is less than the all-electric range, the execution module 230 is further configured to output prompt information that the vehicle needs to be charged at the navigation target location, wherein the all-electric range is used to represent the range of the vehicle in the all-electric driving mode.

[0119] The execution module 230 is further configured to, when the driving mode of the vehicle is the all-electric driving mode, and the vehicle starts driving and the remaining distance of the vehicle to the navigation target location is greater than or equal to the preset remaining distance, determine whether the vehicle satisfies a preset all-electric driving condition based on the remaining distance of the vehicle in the driving process and the range of the vehicle in the remaining amount of the vehicle.

[0120] If not, the execution module 230 is further configured to send a charging request for charging the vehicle battery to the vehicle terminal.

[0121] If the charging authorization request determined based on the charging request is received, the execution module 230 is further configured to output prompt information that the vehicle battery needs to be charged at a location where the vehicle is located.

[0122] If the charging authorization request is not received, the execution module 230 is further configured to, when the remaining amount of the vehicle battery is less than the preset SOC balance point, control the engine in the vehicle to drive the generator to start charging the vehicle battery.

[0123] Or, when the vehicle speed is greater than or equal to a preset vehicle speed threshold, the execution module 230 is further configured to control the engine of the vehicle to directly drive the vehicle.

[0124] When the remaining amount of the vehicle battery is greater than or equal to the preset SOC balance point, or a difference between the range of the vehicle in the remaining amount of the vehicle battery and the distance is greater than a preset distance, the execution module 230 is further configured to control the engine in the vehicle to stop driving the generator to stop charging the vehicle battery, and control the remaining amount of the vehicle battery to reach the preset SOC balance point.

[0125] The execution module 230 is further configured to, when the driving mode of the vehicle is the all-electric driving mode, and the vehicle starts driving and the remaining distance of the vehicle to the navigation target location is greater than or equal to the preset remaining distance, determine whether the vehicle is in the motion mode based on an acceleration driving time of the vehicle in a preset driving time.

[0126] If the vehicle is not in the sport mode, when it is determined that the remaining range under the remaining electric quantity is greater than the preset remaining electric quantity range threshold value, and the preset percentage of the remaining range under the remaining electric quantity is greater than the remaining distance, it is determined that the vehicle meets the preset pure electric driving condition;

[0127] When it is determined that the remaining range under the remaining electric quantity is less than or equal to the preset remaining electric quantity range threshold value, and the preset percentage of the remaining range under the remaining electric quantity is less than or equal to the remaining distance, it is determined that the vehicle does not meet the preset pure electric driving condition.

[0128] For example, in the execution module 230, if the acceleration driving time of the vehicle is greater than the first preset acceleration driving time within the preset driving time, it is determined that the vehicle is in the sport mode.

[0129] If the acceleration driving time of the vehicle is less than the second preset acceleration driving time within the preset driving time, it is determined that the vehicle is not in the sport mode.

[0130] For example, the execution module 230 is also specifically used for:

[0131] If the driving mode of the vehicle is a non-pure electric driving mode, when the vehicle starts driving and the remaining distance of the vehicle to the navigation target is greater than or equal to the preset remaining distance, the remaining electric quantity of the vehicle-mounted battery is less than the preset SOC balance point, the engine in the vehicle is controlled to drive the generator to start charging the vehicle-mounted battery.

[0132] When the remaining electric quantity is greater than or equal to the preset SOC balance point, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle-mounted battery.

[0133] Or when the difference between the remaining range under the remaining electric quantity and the distance is greater than the preset distance, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle-mounted battery, and the remaining electric quantity of the vehicle-mounted battery is controlled to reach the preset SOC balance point.
