[0045] First, the applicable application scenarios of the present application are introduced. The embodiments provided in the present application are applicable to the field of vehicle detection technology.

[0046] Currently, the method of manually adjusting the driving mode of a PHEV vehicle according to the driver's needs does not take into account the SOC balance problem of the vehicle's on-board battery during driving, which will result in a high power supply to the on-board battery, leading to unreasonable energy consumption during driving, thereby affecting the battery's service life.

[0047] Based on this, the embodiments of the present application provide a method, device and storage medium for adjusting the SOC balance point of a vehicle. The embodiments provided by the present application solve the technical problems in the prior art that the vehicle's power supply is high and the vehicle consumes a lot of energy during driving. Compared with selecting a driving method based on user needs, the embodiments provided by the present application adjust the vehicle's SOC balance point based on the navigation trip distance and the remaining power of the vehicle's battery, which can better reduce the power supply and energy consumption under different driving modes, thereby extending the service life of the vehicle's battery.

[0048] Figure 1 A flow chart of a method for adjusting a vehicle SOC balance point provided in an embodiment of the present application, such as Figure 1 The vehicle SOC balance point adjustment method is applied to the battery management module, and the vehicle SOC balance point adjustment method includes the following steps:

[0049] S101. When the vehicle terminal is in navigation mode, obtain the remaining power of the vehicle battery, the vehicle's endurance mileage with the remaining power, and the untraveled distance from the navigation starting point to the navigation target point.

[0050] In this step, the embodiment provided in the present application is controlled by a battery management module (Battery Management System, BMS). After the vehicle starts the navigation mode, the BMS will set the navigation distance to be from the navigation starting point to the navigation destination, and obtain the remaining power of the vehicle battery, the vehicle's endurance mileage with the remaining power, and the untraveled distance from the navigation starting point to the navigation destination in real time.

[0051] It can be understood that the embodiments provided in the present application also need to obtain the pure electric range of the vehicle battery when it is fully charged, and determine whether the vehicle can enable the pure electric range mode within the above-mentioned untraveled distance based on the relationship between the pure electric range and the untraveled distance.

[0052] Among them, it is assumed that the untraveled travel distance in the embodiment provided in this application is represented by Length_R; the pure electric cruising range is represented by Length_C; the remaining power of the vehicle battery is represented by BMS_SOC; and the vehicle's cruising range with the remaining power is represented by Length_C1.

[0053] S102: Based on the travel distance, determine a preset SOC balance point of the vehicle battery at the untraveled travel distance.

[0054] In this step, the embodiment provided by the present application, after determining the untraveled travel distance from the navigation starting point to the navigation target point in the above-mentioned navigation mode, learns the start-stop SOC thresholds corresponding to the engine in each working condition according to the user's driving habits, and thereby determines the preset SOC balance point of the vehicle battery under different lengths of untraveled travel distances.

[0055] In the above, when the vehicle is at different travel distances, it is necessary to determine whether the movement state of the vehicle at the travel distance is the sports mode. If it is determined that the movement state of the vehicle at the travel distance is the sports mode, the corresponding preset SOC balance point in the sports mode is determined to be S_SOC with a high charge.

[0056] It is understandable that, assuming that the embodiment provided in the present application determines different preset SOC balance points according to different untraveled travel distances, specifically but not limited to:

[0057] When Length_R≥100km, the corresponding preset SOC balance point is determined to be H_SOC of medium power; when Length_R<100km, the corresponding preset SOC balance point is determined to be L_SOC of low power. In order to avoid overcharging, over-discharging and insufficient kinetic energy recovery capacity of the on-board battery on the vehicle side, the embodiment provided in the present application manually selects the value of the preset SOC balance point under each working condition between 20% and 80%.

[0058] Among them, the State of Charge (SOC) balance point refers to the ideal power maintenance level of the battery, which refers to the battery power percentage that the vehicle hopes to maintain during operation. Reasonable setting and management of the SOC balance point is crucial to optimizing vehicle performance, fuel economy and battery life.

[0059] S103, performing an operation to make the remaining power of the vehicle battery reach a preset SOC balance point according to the travel distance, the preset remaining travel distance, the remaining power of the vehicle battery, and the possible cruising range under the remaining power.

[0060] In this step, after determining the corresponding preset SOC balance points under different travel distances, the embodiment provided by the present application begins to dynamically adjust the SOC balance point of the vehicle battery according to the travel distance, the preset remaining travel distance, the remaining power of the vehicle battery, and the endurance mileage under the remaining power collected in real time during the driving process of the vehicle, so that the remaining power of the vehicle battery reaches the preset SOC balance point, thereby achieving the purpose of energy saving.

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

[0062] Exemplarily, according to the travel distance, the preset remaining travel distance, the remaining power of the vehicle battery, and the mileage that can be continued under the remaining power, the operation of making the remaining power of the vehicle battery reach the preset SOC balance point includes:

[0063] When the vehicle starts to travel and the remaining distance between the vehicle and the navigation destination is greater than or equal to the preset remaining distance, based on the remaining power of the vehicle battery, the travel distance and the sustainable mileage under the remaining power, the vehicle's engine is controlled to charge the vehicle battery, and the remaining power of the vehicle battery is controlled to reach a preset SOC balance point.

[0064] It should be noted that when the vehicle starts to travel, the remaining travel distance of the vehicle from the navigation target is monitored in real time and represented by Length_R1.

[0065] In the above, when the vehicle starts to travel and the remaining travel distance of the vehicle from the navigation destination is greater than or equal to the preset remaining travel distance, based on the remaining power of the vehicle battery, the travel distance and the mileage that can be continued under the remaining power, the engine of the vehicle is controlled to charge the vehicle battery, and the remaining power of the vehicle battery is controlled to reach the preset SOC balance point, including the following sub-steps:

[0066] Sub-step 1: If the vehicle's driving mode is a pure electric driving mode, when the vehicle starts to travel and the remaining travel distance of the vehicle to the navigation destination is greater than or equal to the preset remaining travel distance, based on the vehicle's remaining travel distance during driving and the mileage that can be reached under the remaining power, determine whether the vehicle meets the preset pure electric driving conditions.

[0067] In the above, it is first necessary to determine the driving mode of the vehicle. The embodiment provided in the present application determines the driving mode of the vehicle by comparing the travel distance Length_R and the pure electric cruising range with Length_C. When Length_C is greater than Length_R, the driving mode of the vehicle is determined to be a pure electric driving mode. When Length_C is less than Length_R, the driving mode of the vehicle is determined to be a non-pure electric driving mode.

[0068] It can be understood that, assuming that the travel distance Length_R in the embodiment provided in the present application includes two types: a long travel distance and a short long travel distance, wherein the long travel distance is specifically: Length_R≥100km. At this time, if Length_C≥125km, the driving mode of the vehicle is determined to be a pure electric driving mode; the segment distance is specifically: Length_R<100km. If Length_C≥100km, the driving mode of the vehicle is determined to be a pure electric driving mode.

[0069] Exemplarily, when the vehicle's driving mode is a pure electric driving mode, when the vehicle starts driving and the remaining driving distance of the vehicle to the navigation destination is greater than or equal to a preset remaining driving distance, it is determined whether the vehicle meets the preset pure electric driving conditions based on the remaining driving distance of the vehicle during driving and the endurance mileage with the remaining power.

[0070] Here, when it is determined that the vehicle's driving mode is a pure electric driving mode, when the vehicle starts to travel and Length_R1 is greater than or equal to the preset remaining travel distance, it is determined that the range of cruising under the remaining power is greater than the preset remaining power range threshold, and the preset percentage of the range of cruising under the remaining power is greater than the remaining travel distance. If so, it is determined that the vehicle meets the preset pure electric driving conditions; if not, it is determined that the vehicle does not meet the preset pure electric driving conditions.

[0071] Among them, the preset remaining battery life mileage threshold can be customized according to different application scenarios. It is assumed that the remaining battery life mileage threshold in the embodiment provided in this application is specifically 65km.

[0072] Sub-step 2: If not satisfied, a charging request for charging the vehicle battery is sent to the vehicle terminal.

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

[0074] Sub-step 3: If a charging authorization request determined based on the charging request is received, a prompt message is outputted indicating that the vehicle battery needs to be charged at the location of the vehicle.

[0075] In the above, after the user operates on the vehicle terminal to confirm acceptance of the charging request, the vehicle terminal receives a charging authorization request determined based on the charging request. At this time, a prompt message for charging the vehicle battery at the location of the vehicle is output, wherein the prompt information here is specific but not limited to the location information of nearby charging stations.

[0076] Sub-step 4: If no charging authorization request is received, when the remaining power of the vehicle-mounted battery is less than the preset SOC balance point, control the engine in the vehicle 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, control the engine of the vehicle to directly drive the vehicle.

[0077] It should be noted that if the user operates on the vehicle-mounted terminal to determine to accept the charging request, and at this time the vehicle-mounted terminal does not receive the charging authorization request determined based on the charging request, then when the remaining power of the vehicle-mounted battery is less than the preset SOC balance point (i.e., BMS_SOC < H_SOC) or the vehicle speed is greater than or equal to the preset vehicle speed threshold, control the engine of the vehicle to directly drive the vehicle.

[0078] Among them, the preset vehicle speed threshold in the embodiments provided by the present application can be customarily selected and used according to different application scenarios. It is assumed that the preset vehicle speed threshold in the embodiments provided by the present application can be specifically but not limited to 80 km / 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 when the difference between the remaining mileage at the remaining power and the travel distance is greater than the preset distance, control the engine in the vehicle to stop driving the generator to stop charging the vehicle-mounted battery, and control the remaining power of the vehicle-mounted battery to reach the preset SOC balance point.

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

[0081] Among them, the preset distance in the embodiments provided by the present application can be customarily selected and used according to different application scenarios. It is assumed that the preset distance in the embodiments provided by the present application can be specifically but not limited to 50 km.

[0082] Exemplarily, when the remaining travel distance of the vehicle from the navigation destination is less than the preset remaining travel 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 mileage at the remaining power is less than the pure electric driving mileage, a prompt message for charging the vehicle at the navigation destination is output, where the pure electric driving mileage is used to represent the mileage of the vehicle in the pure electric driving mode.

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

[0084] Among them, the preset power difference in the embodiment provided in the present application can be customized and used according to different application scenarios. It is assumed that the preset power difference in the embodiment provided in the present application can be specifically but not limited to 10% H_SOC.

[0085] Exemplarily, if the driving mode of the vehicle is the pure electric driving mode, when the vehicle starts to travel and the remaining travel distance of the vehicle to the navigation destination is greater than or equal to the preset remaining travel distance, based on the remaining travel distance of the vehicle during the driving process and the mileage that can be continued under the remaining power, determining whether the vehicle meets the preset pure electric driving condition includes the following sub-steps:

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

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

[0088] In the above, the embodiment provided in the present application accelerates the vehicle by the accelerator pedal opening, and determines the acceleration driving time by the accumulated time when the accelerator pedal opening is ≥ 70%.

[0089] Here, the first preset acceleration driving time and the second preset acceleration driving time in the embodiment provided by the present application can be customized and used according to different application scenarios. It is assumed that the first preset acceleration driving time in the embodiment provided by the present application can be specific but not limited to 30s; the second preset acceleration driving time can be specific but not limited to 15s.

[0090] Sub-step 2: If the vehicle is not in sports mode, when it is determined that the range of the remaining power is greater than the preset range threshold of the remaining power, and the preset percentage of the range of the remaining power is greater than the remaining travel distance, it is determined that the vehicle meets the preset pure electric drive conditions.

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

[0092] Among them, the preset remaining power range threshold in the embodiment provided in this application can be specific but not limited to 65km.

[0093] Sub-step 3: When it is determined that the cruising range with the remaining power is less than or equal to the preset remaining power cruising range threshold, and the preset percentage of the cruising range with the remaining power is less than or equal to the remaining travel distance, it is determined that the vehicle does not meet the preset pure electric drive condition.

[0094] It should be noted that if Length_C1≤65km, and Length_C1*80%≤Length_R1, it is determined that the vehicle does not meet the preset pure electric drive condition.

[0095] Exemplarily, if the vehicle's driving mode is a non-pure electric driving mode, when the vehicle starts driving and the remaining travel distance of the vehicle to the navigation destination is greater than or equal to the preset remaining travel distance, when the remaining power of the vehicle 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 battery; when the remaining power 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 cruising range and the travel distance under 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 battery, and the remaining power of the vehicle battery 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 to travel and Length_R1 is greater than or equal to 1 km, when BMS_SOC is less than H_SOC, the engine in the vehicle is controlled to drive the generator to start charging the on-board 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 on-board battery, or when Length_C1-Length_R≥50 km, the engine in the vehicle is controlled to stop driving the generator to stop charging the on-board battery, and the remaining power of the on-board battery is controlled to reach a preset SOC balance point.

[0097] The following is illustrated by specific embodiments:

[0098] Embodiment 1:

[0099] Sub-step 1: Assume Length_R ≥ 100 km.

[0100] Sub-step 2: At this time, if Length_C ≥ 125 km, the pure electric drive mode is preferentially used; if Length_C < 125 km, the engine is started when BMS_SOC < H_SOC.

[0101] Then, when Length_C1 - Length_R1 ≥ 50 km, or BMS_SOC ≥ H_SOC, the engine is controlled to stop.

[0102] Sub-step 2: When the vehicle starts to drive, if Length_C1 ≤ 65 km and Length_C1 * 70% ≤ Length_R1, at this time, the in-vehicle terminal will send a charging request. If the user agrees to the charging request, when Length_C1 ≤ 65 km and Length_C1 * 70% ≤ Length_R1 are satisfied again, the in-vehicle terminal will still send a charging request. If the user does not agree to the charging request, the engine is started when the detected vehicle speed ≥ 80 km / h or BMS_SOC < H_SOC.

[0103] Sub-step 3: After the engine is started, it is monitored in real time. When Length_C1 - Length_R1 ≥ 50 km, or BMS_SOC ≥ H_SOC, the engine is controlled to stop.

[0104] Embodiment 2:

[0105] Sub-step 1: Assume Length_R < 100 km.

[0106] Sub-step 2: At this time, if Length_C ≥ 125 km, the pure electric drive mode is preferentially used;

[0107] If Length_C < 125 km, the engine is started when BMS_SOC < L_SOC; and when Length_C1 - Length_R1 ≥ 50 km, or BMS_SOC ≥ L_SOC, the engine is controlled to stop.

[0108] Sub-step 2: During the process of the vehicle starting to drive, if Length_C1 ≤ 65 km and Length_C1 * 70% ≤ Length_R1, at this time, the in-vehicle terminal will send a charging request. If the user agrees to the charging request, then when Length_C1 ≤ 65 km and Length_C1 * 70% ≤ Length_R1 are satisfied again, the in-vehicle terminal will still send a charging request. If the user does not agree to the charging request, then when the detected vehicle speed ≥ 80 km / h or BMS_SOC < L_SOC, the engine is started.

[0109] Sub-step 3: After the engine is started, monitor in real time. When Length_C1 - Length_R1 ≥ 50 km, or BMS_SOC ≥ L_SOC, control the engine to shut down.

[0110] The method for adjusting the SOC balance point of the vehicle provided by the embodiment of the present application, compared with the prior art, the embodiment provided by the present application is based on the travel distance to determine the preset SOC balance point of the in-vehicle battery under the remaining travel distance, and according to the travel distance, the preset remaining travel distance, the remaining power of the in-vehicle battery, and the available cruising range at the remaining power, perform the operation to make the remaining power of the in-vehicle battery reach the preset SOC balance point. Compared with the method of selecting the drive according to the user's needs, the method of adjusting the vehicle SOC balance point based on the navigation travel distance and the remaining power of the in-vehicle battery can more effectively reduce the feed power and energy consumption under different drive modes, and thus extend the service life of the in-vehicle battery.

[0111] Figure 2 It is a structural block diagram of a device for adjusting the SOC balance point of a vehicle provided by an embodiment of the present application. As Figure 2 shown, the device 200 for adjusting the SOC balance point of the vehicle includes:

[0112] An acquisition module 210, configured to acquire the remaining power of the in-vehicle battery, the available cruising range of the vehicle at the remaining power, and the remaining travel distance from the navigation starting point to the navigation destination when the in-vehicle terminal is in the navigation mode.

[0113] A determination module 220, configured to determine the preset SOC balance point of the in-vehicle battery under the remaining travel distance based on the travel distance.

[0114] An execution module 230, configured to perform an operation to make the remaining power of the in-vehicle battery reach the preset SOC balance point according to the travel distance, the preset remaining travel distance, the remaining power of the in-vehicle battery, and the available cruising range at the remaining power.

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

[0116] When the vehicle starts to travel and the remaining distance between the vehicle and the navigation destination is greater than or equal to the preset remaining distance, based on the remaining power of the vehicle battery, the travel distance and the sustainable mileage under the remaining power, the vehicle's engine is controlled to charge the vehicle battery, and the remaining power of the vehicle battery is controlled to reach a preset SOC balance point.

[0117] Exemplarily, the execution module 230 is further specifically configured to:

[0118] When the remaining travel distance of the vehicle to the navigation destination is less than the preset remaining travel distance, and the power difference between the vehicle's remaining power and the preset SOC balance point is less than the preset power difference, or the cruising range with the remaining power is less than the pure electric cruising range, a prompt message is output that the vehicle needs to be charged at the navigation destination, where the pure electric cruising range is used to characterize the vehicle's cruising range in pure electric drive mode.

[0119] Exemplarily, in the execution module 230, if the driving mode of the vehicle is the pure electric driving mode, when the vehicle starts to travel and the remaining travel distance of the vehicle to the navigation destination is greater than or equal to the preset remaining travel distance, based on the remaining travel distance of the vehicle during the driving process and the mileage that can be continued under the remaining power, it is determined whether the vehicle meets the preset pure electric driving condition;

[0120] If not, a charging request is sent to the vehicle terminal to charge the vehicle battery;

[0121] If a charging authorization request is received based on the charging request, a prompt message is outputted indicating that the vehicle battery needs to be charged at the location of the vehicle;

[0122] If no charging authorization request is received, when the remaining power of the vehicle 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 battery;

[0123] or, when the speed of the vehicle is greater than or equal to a preset speed threshold, controlling the engine of the vehicle to directly drive the vehicle;

[0124] When the remaining power of the vehicle battery is greater than or equal to the preset SOC balance point, or when the difference between the cruising range and the travel distance at 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 battery, and the remaining power of the vehicle battery is controlled to reach the preset SOC balance point.

[0125] Exemplarily, in the execution module 230, if the driving mode of the vehicle is the pure electric driving mode, when the vehicle starts to travel and the remaining travel distance of the vehicle from the navigation destination is greater than or equal to the preset remaining travel distance, it is determined whether the vehicle is in the sports mode based on the acceleration driving time of the vehicle within the preset driving time;

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

[0127] When it is determined that the cruising range with the remaining power is less than or equal to the preset remaining power cruising range threshold, and the preset percentage of the cruising range with the remaining power is less than or equal to the remaining travel distance, it is determined that the vehicle does not meet the preset pure electric drive conditions.

[0128] Exemplarily, in the execution module 230, if within the preset driving duration, the acceleration driving duration of the vehicle is greater than the first preset acceleration driving duration, it is determined that the vehicle is in the sport mode;

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

[0130] Exemplarily, the execution module 230 is further specifically configured to:

[0131] If the driving mode of the vehicle is a non-pure electric driving mode, when the vehicle starts to travel and the remaining travel distance of the vehicle to the navigation destination is greater than or equal to the preset remaining travel distance, when the remaining power of the vehicle 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 battery;

[0132] When the remaining power is greater than or equal to a preset SOC balance point, controlling the engine in the vehicle to stop driving the generator to stop charging the vehicle battery;

[0133] Or when the difference between the mileage that can be reached with the remaining power and the travel distance is greater than a preset distance, the engine in the vehicle is controlled to stop driving the generator to stop charging the vehicle battery, and the remaining power of the vehicle battery is controlled to reach a preset SOC balance point.

[0134] The vehicle SOC balance point adjustment device 200 provided in the embodiment of the present application, compared with the prior art, determines a preset SOC balance point of the vehicle battery at an untraveled travel distance based on the travel distance, and performs an operation to make the remaining power of the vehicle battery reach the preset SOC balance point according to the travel distance, the preset remaining travel distance, the remaining power of the vehicle battery and the sustainable mileage under the remaining power. Compared with selecting a driving method according to user needs, the method of adjusting the vehicle SOC balance point based on the navigation travel distance and the remaining power of the vehicle battery can better reduce the power feed and energy consumption under different driving modes, thereby extending the service life of the vehicle battery.
