Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more specifically, to a power balance optimization method, a power balance optimization device, an electronic device, and a storage medium. Background Technology

[0002] For range-extended electric vehicles (REVs), plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs), maintaining battery balance is a crucial function. Battery balance refers to the system's use of the engine to charge the vehicle when the battery charge falls below a set equilibrium point, ensuring sufficient power for the vehicle. This equilibrium point, known as the target State of Charge (SOC), is closely related to user-set driving modes (e.g., fuel priority, electric priority), driving modes (e.g., ECO, SPORT), vehicle speed, altitude, and ambient temperature. If the battery charge is significantly below the set equilibrium point, it can limit the vehicle's driving power, or lead to poor noise and vibration (NVH) characteristics on flat roads due to a low SOC, and in more severe cases, even vehicle breakdown.

[0003] Currently, REV, PHEV, or HEV models employ a series power generation mode in low-speed ranges, such as below 40 km / h. In this mode, the engine operates, driving the generator via gears or belts to convert mechanical energy into electrical energy. The generator then transmits this electrical energy to the engine and battery via high-voltage lines, thus propelling the vehicle.

[0004] However, current generators generally have a power output of around 60kW. During prolonged low-speed uphill driving in mountainous areas, the battery charge cannot be balanced, and there's even a possibility of the battery running out of power while the fuel supply is plentiful. The root cause, besides insufficient power generation, is that high engine coolant or intake air temperatures reduce engine performance and torque, forcing the battery to output more power to meet the user's uphill driving needs. Specifically, high engine intake air or coolant temperatures reduce the engine's power generation capacity. A crucial factor here is that most range extender engines use mechanical water pumps. The water pump flow rate and speed are positively correlated with engine speed. If the engine stops working, the engine coolant circuit cannot circulate, potentially leading to insufficient engine cooling. If the engine speed is low, the water pump speed is also low, resulting in low water flow in the engine circuit and poor cooling. Under low-speed, high-load conditions, insufficient engine cooling leads to high engine coolant temperature, reduced engine torque, and insufficient range extender power generation. In such cases, the torque limiting threshold is highly likely to be triggered, which is extremely detrimental to the overall vehicle battery balance.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] In a first aspect, the present invention proposes a power balance optimization method, comprising: acquiring relevant vehicle parameters in real time in vehicle series power generation mode; determining whether the relevant vehicle parameters at the current moment meet a first preset condition; activating and entering a series power generation speed increase strategy to correct the current power generation speed if the relevant vehicle parameters meet the first preset condition; and controlling the vehicle to enter normal power generation mode if the relevant vehicle parameters do not meet the first preset condition.

[0008] Optionally, determining whether the vehicle-related parameters meet the first preset condition includes: determining whether the vehicle-related parameters meet the first threshold condition and whether the duration of meeting the first threshold condition is greater than or equal to the first time threshold.

[0009] Optionally, after activating and entering the series power generation speed enhancement strategy when the vehicle-related parameters meet the first preset condition, the method further includes: determining whether the vehicle-related parameters at the current moment meet the second preset condition; controlling the vehicle to enter normal power generation mode when the vehicle-related parameters meet the second preset condition; and reactivating and incorporating the series power generation speed enhancement strategy when the vehicle-related parameters do not meet the second preset condition to correct the current power generation speed. The determination of whether the vehicle-related parameters at the current moment meet the second preset condition includes: determining whether the vehicle-related parameters meet the second threshold condition and whether the duration of meeting the second threshold condition is greater than or equal to the second time threshold.

[0010] Optionally, a series generator speed increase strategy is activated and entered to correct the current generator speed, including: keeping the vehicle's current generator power unchanged, adding the current target generator speed to the offset to obtain the corrected speed, and increasing the current generator speed to the corrected speed.

[0011] Optionally, the offset includes the engine speed corresponding to the engine coolant temperature and / or engine intake air temperature in the vehicle-related parameters that meet the first preset condition.

[0012] Optionally, increasing the current power generation speed to the corrected speed includes: increasing the current power generation speed to the corrected speed with an acceleration not exceeding the gradient threshold.

[0013] Optionally, the method further includes: acquiring control parameters and adjusting the vehicle's power mode based on the control parameters.

[0014] Secondly, a power balance optimization device is also proposed, comprising:

[0015] The parameter acquisition module is used to acquire relevant vehicle parameters in real time during vehicle series power generation mode.

[0016] The judgment module is used to determine whether the relevant parameters of the whole vehicle at the current moment meet the first preset condition;

[0017] The execution module is used to activate and enter the series generator speed increase strategy when the relevant parameters of the whole vehicle meet the first preset condition, so as to correct the current generator speed.

[0018] The execution module is also used to control the vehicle to enter normal power generation mode when the relevant parameters of the vehicle do not meet the first preset conditions.

[0019] Thirdly, an electronic device is also proposed, including a processor and a memory, wherein the memory stores computer program instructions, which are executed by the processor to perform the power balancing optimization method as described above.

[0020] Fourthly, a storage medium is also proposed, on which program instructions are stored. When the program instructions are run, they are used to execute the power balance optimization method described above.

[0021] According to the above technical solution, firstly, relevant vehicle parameters are acquired, and it is determined whether the current vehicle parameters meet a first preset condition. Then, different operations are performed based on different judgment results. If the first preset condition is met, the current generator speed is increased; if the first preset condition is not met, the vehicle is controlled to enter normal generator operation. This effectively corrects the current generator speed; that is, by increasing the current generator speed, the engine circuit flow is significantly increased, thereby effectively reducing the coolant temperature and preventing further rise in engine coolant temperature that could trigger the torque limiting threshold, thus ensuring the overall vehicle electrical balance.

Then, different operations are performed based on different judgment results. If the first preset condition is met, the current generator speed is increased; if the first preset condition is not met, the vehicle is controlled to enter normal generator operation.

The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0031] According to a first aspect of the present invention, a power balance optimization method is proposed. Figure 1 A schematic flowchart of a power balance optimization method 100 according to an embodiment of the present invention is shown. Figure 1 As shown, method 100 may include the following steps.

[0032] Step S110: In the vehicle series power generation mode, acquire relevant vehicle parameters in real time.

[0033] Optionally, the control parameters may include vehicle speed, SOC, altitude, ambient temperature, and user-set parameters. Based on the control parameters, the power battery's charge balance point can be set, for example, 20%. Furthermore, the vehicle's power mode can be adjusted according to the aforementioned control parameters. It is understood that this step can be performed before step S110. In this embodiment, based on the aforementioned control parameters, the vehicle's power mode is adjusted to a series power generation mode.

[0034] When the vehicle is in series power generation mode, the vehicle controller can select the optimal economic curve discrete point based on the universal characteristic curve, and can also consider NVH (Noise, Vibration, and Harshness) to select the power generation operating point. Specifically, the target power generation can be calculated based on parameters such as vehicle speed, SOC (State of Charge), required power, and target SOC. Furthermore, the target power generation speed is selected based on the optimal economic curve of the generator and engine combined with NVH characteristics. Any existing or future technical solutions that can obtain the target power generation and target power generation speed are within the scope of protection of this application and are not limited thereto. Optionally, vehicle-related parameters may include vehicle speed, gear position, engine coolant temperature, engine intake air temperature, SOC, actual engine output power signal, current target speed, and current target power generation. The target speed can be obtained from the vehicle controller.

[0035] Step S120: Determine whether the vehicle-related parameters at the current moment meet the first preset condition.

[0036] Specifically, this can include determining whether vehicle-related parameters meet a first threshold condition and whether the duration of meeting the first threshold condition is greater than or equal to a first time threshold. The first threshold condition may include: 1) engine intake air temperature greater than or equal to a first temperature threshold or engine coolant temperature greater than and / or equal to a second temperature threshold; 2) vehicle power generation greater than or equal to a first power threshold; 3) vehicle speed greater than or equal to a first speed threshold; 4) SOC greater than or equal to a first battery percentage threshold. It is understood that vehicle-related parameters can only be determined to meet the first threshold condition if all four sub-conditions are met. In other words, if any one sub-condition is not met, the vehicle-related parameters are considered not to meet the first threshold condition. Furthermore, it is understood that vehicle-related parameters can change during vehicle movement, therefore the above judgment process can be performed in real time. After the vehicle-related parameters meet the first threshold condition, it is further determined whether the changing vehicle-related parameters can continuously meet the first threshold condition. If the duration of continuously meeting the first threshold condition is greater than or equal to a first time threshold, the vehicle-related parameters at the current moment can be considered to meet a first preset condition. Optionally, the first temperature threshold can be any reasonable value such as 70 degrees Celsius or 72 degrees Celsius; the second temperature threshold can be any reasonable value such as 110 degrees Celsius or 112 degrees Celsius; the first power threshold can be any reasonable value such as 20 kW or 21 kW; the first speed threshold can be any reasonable value such as 10 km / h or 15 km / h; the first battery percentage threshold can be any reasonable value such as 30% or 35%; and the first time threshold can be any reasonable value such as 60 seconds or 70 seconds. Preferably, in addition to the first threshold condition and the determination of the duration of satisfaction, it can also be determined whether the vehicle is currently in a forward gear, and the determination result, together with the above two determination results, is used as the determination result of whether the relevant parameters of the vehicle at the current moment meet the first preset condition.

[0037] Step S130: If the relevant parameters of the whole vehicle meet the first preset condition, activate and enter the series generator speed increase strategy to correct the current generator speed.

[0038] Based on the above judgment results, if the relevant parameters of the vehicle meet the first preset condition, a series generator speed increase strategy can be executed. That is, the current generator speed can be increased to a certain speed value. This speed value can be calculated based on the vehicle's operating conditions or preset to a fixed value based on experience; no limitation is made here. This achieves the correction of the current generator speed.

[0039] Step S140: If the relevant parameters of the vehicle do not meet the first preset condition, control the vehicle to enter the normal power generation mode.

[0040] If, based on the above judgment results, it is determined that the relevant parameters of the vehicle do not meet the first preset condition, the vehicle can be controlled to enter normal power generation mode. In this embodiment, the vehicle is in series power generation mode, that is, the vehicle is controlled to enter normal series power generation mode. Under this mode, the target power generation is also calculated based on vehicle speed, SOC, demand power, target SOC, etc., and the target power generation speed is also selected based on the optimal economic curve and NVH characteristics of the engine and generator combined.

[0041] According to the above technical solution, firstly, relevant vehicle parameters are acquired, and it is determined whether the current vehicle parameters meet a first preset condition. Then, different operations are performed based on different judgment results. If the first preset condition is met, the current generator speed is increased; if the first preset condition is not met, the vehicle is controlled to enter normal generator operation. This effectively corrects the current generator speed; that is, by increasing the current generator speed, the engine circuit flow is significantly increased, thereby effectively reducing the coolant temperature and preventing further rise in engine coolant temperature that could trigger the torque limiting threshold, thus ensuring the overall vehicle electrical balance.

[0042] In one embodiment, after activating and entering the series generator speed increase strategy in step S130 when the vehicle-related parameters meet the first preset condition, the method may further include the following steps. Figure 2 A schematic flowchart of a power balance optimization method 100 according to another embodiment of the present invention is shown. Figure 2 As shown, method 100 may further include the following steps after step S130.

[0043] Step S150: Determine whether the vehicle-related parameters at the current moment meet the second preset condition.

[0044] Specifically, this may include determining whether relevant vehicle parameters meet a second threshold condition and whether the duration of meeting the second threshold condition is greater than or equal to a second time threshold. The second threshold condition may include: 1) the engine intake air temperature is less than a third temperature threshold and / or the engine coolant temperature is less than a fourth temperature threshold;

[0045] 2) The vehicle's power generation is less than the second power threshold; 3) The State of Charge (SOC) is greater than or equal to the second percentage of energy threshold. It can be understood that the vehicle's relevant parameters can only be determined to meet the second threshold condition if all three sub-conditions are satisfied. In other words, if any one sub-condition is not met, the vehicle's relevant parameters are considered not to meet the second threshold condition. Furthermore, it can be understood that the vehicle's relevant parameters can change during vehicle movement, so the above judgment process can be performed in real time. After the vehicle's relevant parameters meet the second threshold condition, it is further determined whether the changing vehicle's relevant parameters can continuously meet the second threshold condition. If the duration of continuously meeting the second threshold condition is greater than or equal to the second time threshold, the vehicle's relevant parameters at the current moment can be considered to meet the second preset condition. Optionally, the third temperature threshold can be any reasonable value such as 60 degrees Celsius or 58 degrees Celsius, the fourth temperature threshold can be any reasonable value such as 105 degrees Celsius or 103 degrees Celsius, the second power threshold can be any reasonable value such as 10 kilowatts or 11 kilowatts, the second power percentage threshold can be any reasonable value such as 40% or 45%, and the second time threshold can be equal to the first time threshold, for example, it can also be set to any reasonable value such as 60 seconds or 70 seconds.

[0046] Step S160: If the relevant parameters of the vehicle meet the second preset condition, control the vehicle to enter the normal power generation mode.

[0047] If, based on the above judgment results, it is determined that the relevant parameters of the vehicle meet the second preset condition, the vehicle can then be controlled to enter normal power generation mode. In this embodiment, the vehicle is in series power generation mode, that is, the vehicle is controlled to enter normal series power generation mode. Under this mode, the target power generation is also calculated based on vehicle speed, SOC, required power, target SOC, etc., and the target power generation speed is also selected based on the optimal economic curve and NVH characteristics of the engine and generator combined.

[0048] In step S170, if the relevant parameters of the vehicle do not meet the second preset condition, the series generator speed increase strategy is activated again to correct the current generator speed.

[0049] Based on the above judgment results, if the relevant parameters of the vehicle do not meet the second preset condition, a series generator speed increase strategy can be implemented. That is, the current generator speed can be increased to a certain speed value. This speed value can be calculated based on the vehicle's operating conditions or preset to a fixed value based on experience; no limitation is made here. This achieves the correction of the current generator speed.

[0050] Therefore, by further adjusting the current generator speed using the second preset condition, the cooling effect of the engine coolant is further ensured, providing a more reliable guarantee for battery balance. In addition, the setting of the first and second preset conditions can use software strategies at low cost to solve the problem of battery imbalance under long-term low-speed uphill conditions. Furthermore, the battery balance problem under aggressive driving conditions and high-speed driving conditions can also be optimized and improved.

[0051] It is understood that there is no specific order of execution between steps S130 and S140, or between steps S160 and S170. These steps simply represent different operations performed based on the judgment result. In a single judgment, only one of steps S130 and S140 is executed; similarly, only one of steps S160 and S170 is executed.

[0052] Optionally, activating and entering the series generator speed increase strategy in steps S130 and S170 to correct the current generator speed may include: keeping the current generator power of the vehicle unchanged, adding the current target generator speed to the offset to obtain the corrected speed, and increasing the current generator speed to the corrected speed.

[0053] For example, at a vehicle speed of 30 km / h, with the power balance point set at 20% according to the above technical solution, the calculated target power generation is 30 kW and the target power generation speed is 2500 rpm. Adding an offset to the target power generation speed yields the corrected speed. This offset can include the engine speed corresponding to the engine coolant temperature and / or engine intake air temperature, which are vehicle-related parameters that meet the first preset condition. Specifically, if step S120 determines that both the engine coolant temperature and engine intake air temperature meet the first preset condition, the engine speed corresponding to the current engine coolant temperature and the current engine intake air temperature can be determined using a lookup table. The sum of these two engine speeds can then be used as an offset and added to the target power generation speed to obtain the corrected speed. Alternatively, if step S120 determines that either the engine coolant temperature or the engine intake air temperature meets the first preset condition, the engine speed corresponding to the temperature meeting the condition can be determined using a lookup table, and this engine speed can be added as an offset to the target power generation speed to obtain the corrected speed. Specifically, the current engine coolant temperature is 115 degrees Celsius, which is higher than the second temperature threshold, while the current engine inlet water temperature is 65 degrees Celsius, which is lower than the first temperature threshold. Therefore, the engine coolant temperature meets the requirements. Next, by looking up a table, the engine speed corresponding to a coolant temperature of 115 degrees Celsius is determined to be 700 rpm, i.e., an offset of 700 rpm. Thus, adding the offset of 700 rpm to the target generator speed of 2500 rpm yields a corrected speed of 3200 rpm. Finally, the current generator speed can be increased to 3200 rpm.

[0054] The above technical solution has a simple and easy-to-implement algorithm, requires little computation, and is less likely to produce errors.

[0055] Preferably, during the process of increasing the current power generation speed to the corrected speed, the current power generation speed is increased to the corrected speed at an acceleration not exceeding the gradient threshold. The gradient threshold can be reasonably set based on experience and is not limited here.

[0056] This effectively prevents the generator speed from changing too quickly and causing a whistling sound, thus affecting the user experience.

[0057] Figure 3 A schematic flowchart of a power balance optimization method 100 according to yet another embodiment of the present invention is shown. Figure 3As shown, firstly, the relevant parameters of the whole vehicle are acquired, and it is determined whether the relevant parameters of the whole vehicle at the current moment meet the first preset condition. If not, the normal series power generation mode is entered. Otherwise, if the first preset condition is met, the series power generation speed increase strategy is activated and entered. After the power generation speed is increased, it is determined again whether the relevant parameters of the whole vehicle at the current moment meet the second preset condition. If the second preset condition is met, the normal series power generation mode is entered. If the second preset condition is not met, the series power generation speed increase strategy is entered again. The above judgment process can be continuously performed until the normal series power generation mode is entered.

[0060] The judgment module 420 is used to determine whether the relevant parameters of the whole vehicle at the current moment meet the first preset condition.

[0061] The execution module 430 is used to activate and enter the series generator speed increase strategy when the relevant parameters of the vehicle meet the first preset condition, so as to correct the current generator speed. The execution module 430 is also used to control the vehicle to enter the normal generator operation condition when the relevant parameters of the vehicle do not meet the first preset condition.
