[0028] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0029] In the following description, the words "first" and "second" are used only to distinguish the purpose of the description and should not be interpreted as indicating or implying relative importance or order.

[0030] First, the application scenario of this disclosure is explained. This disclosure is applied to the application scenario of controlling multiple power units in a fuel cell vehicle. In this scenario, the vehicle includes multiple power units, such as fuel cells, hydrogen internal combustion engines, and supercapacitors. The fuel cells, hydrogen internal combustion engines, and supercapacitors are all connected to the vehicle's drive system to provide output power to the vehicle.

[0031] In related technologies, fuel cells are clean batteries that generate electricity through electrochemical reactions. Due to their high efficiency and pollution-free operation, they have become one of the important development directions for future new energy vehicle engines. However, due to current technological limitations, the output power of a single fuel cell system cannot meet the vehicle's power requirements. Therefore, hybrid power systems, combining fuel cells and power batteries, are commonly used to jointly provide power. However, in current hybrid systems, the energy transfer chain between the fuel cell and the power battery is relatively long, resulting in lower power drive efficiency and higher vehicle energy consumption.

[0032] To address the aforementioned problems, this disclosure provides a vehicle control method, apparatus, electronic device, and vehicle. This method acquires the vehicle's required power during operation, the first SOC (State of Charge) value of the vehicle's supercapacitor, the current fuel cell power output, and the current internal combustion engine power output. Based on the required power, it determines the corresponding target operating mode for the vehicle. Furthermore, based on the target operating mode, the first SOC value, the current fuel cell power, and the current internal combustion engine power, it determines the target output power for the fuel cell, hydrogen internal combustion engine, and supercapacitor, respectively, thereby controlling the vehicle to operate at the determined target output power. This allows for the determination of different vehicle operating modes based on the required power. For each operating mode, the output power of the vehicle's multiple power units is distributed according to the supercapacitor's state of charge to adapt to different operating modes. This ensures that all power units operate at their optimal state, achieving effective control of the vehicle's output power under different operating modes, improving vehicle operating efficiency, and reducing vehicle energy consumption.

[0033] The present disclosure will now be described in conjunction with specific embodiments.

[0034] Figure 1 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment, such as... Figure 1 As shown, the vehicle includes: a supercapacitor, a fuel cell, and a hydrogen internal combustion engine, and the method may include: In step S11, the power demand of the vehicle during driving, the first SOC value of the supercapacitor, the current fuel cell power output of the fuel cell, and the current internal combustion engine power output of the hydrogen internal combustion engine are obtained.

[0035] The fuel cell, the hydrogen internal combustion engine, and the supercapacitor are all connected to the vehicle's drive system. The fuel cell is connected in series with the hydrogen internal combustion engine, and the fuel cell is connected in parallel with the supercapacitor.

[0036] In this step, if the accelerator pedal travel exceeds a preset travel threshold, the vehicle is determined to be in motion. At this point, the required power can be calculated by acquiring the rolling resistance of the road surface and the air resistance of the air, combined with the vehicle speed. This supercapacitor can supplement the power consumed by the vehicle under high load and can recover and store surplus electrical energy generated by other vehicle power units when the vehicle is under low load. The state of charge (SOC) characterizes the remaining capacity of the supercapacitor, numerically defined as the ratio of the remaining capacity to the battery capacity of the supercapacitor, ranging from 0 to 1. When SOC = 0, the battery is fully discharged; when SOC = 1, the battery is fully charged. Here, the current fuel cell power output can be calculated by measuring the output voltage and current of the fuel cell. Similarly, the current internal combustion engine power output can be calculated by measuring the speed and torque of the hydrogen internal combustion engine.

[0037] It should be noted that the calculation methods for the required power, the current fuel cell power, and the current internal combustion engine power can refer to the power determination methods in the existing technology, and will not be repeated here.

[0038] In step S12, the target operating mode corresponding to the vehicle is determined based on the required power.

[0039] The target operating mode can include idling mode, battery operating mode, internal combustion engine operating mode, and a combined operating mode. In idling mode, the internal combustion engine is idle, and the supercapacitor is prioritized as the vehicle's power output. Based on the high efficiency of the fuel cell in its low-power range, the fuel cell serves as a supplementary power source. In battery operating mode, the fuel cell operates in its high-efficiency range to output electrical energy to the vehicle's electric motor, providing power to the vehicle, with the supercapacitor serving as a supplementary power source. In internal combustion engine operating mode, the hydrogen internal combustion engine operates in its high-efficiency range to provide power to the vehicle, with the supercapacitor serving as a supplementary power source. The combined operating mode indicates that the fuel cell, the hydrogen internal combustion engine, and the supercapacitor simultaneously drive the vehicle's electric motor. In this combined operating mode, both the fuel cell and the hydrogen internal combustion engine operate in their high-efficiency ranges to simultaneously drive the vehicle's electric motor, with the supercapacitor serving as a supplementary power source. Additionally, in other embodiments, the vehicle can also be configured with a regenerative braking mode, which converts the kinetic energy generated during vehicle deceleration or braking into electrical energy and charges the supercapacitor.

[0040] In step S13, the target output power corresponding to the fuel cell, the hydrogen internal combustion engine, and the supercapacitor is determined based on the target operating mode, the first SOC value, the current fuel cell power, and the current internal combustion engine power.

[0041] Specifically, in each target operating mode of the vehicle, the first SOC value can be used to determine whether the supercapacitor needs to output power to supplement the vehicle's power, thereby determining the target output power corresponding to the fuel cell, the hydrogen internal combustion engine, and the supercapacitor.

[0042] In step S14, the vehicle is controlled to drive according to the target output power corresponding to the fuel cell, the hydrogen internal combustion engine, and the supercapacitor, respectively.

[0043] By using the above method, different operating modes of the vehicle can be determined according to the vehicle's power requirements. For each operating mode, the output power of multiple power units of the vehicle can be distributed in combination with the state of charge of the vehicle's supercapacitor to adapt to the different operating modes of the vehicle. This allows multiple power units to be in the optimal operating state, realizes effective control of the output power of the vehicle in different operating modes, improves the vehicle's operating efficiency, and reduces the vehicle's energy consumption.

[0044] In some embodiments, step S12 above may include the following: Scenario 1: If the required power is less than or equal to the first battery power threshold, the target operating mode is determined to be idle mode.

[0045] Among them, the first battery power threshold This can be the minimum output power of the fuel cell. For example, the power required by the vehicle. satisfy At this time, the vehicle's power demand is relatively low, so the target operating mode is determined to be the idle mode, and the internal combustion engine is in an unloaded state. The supercapacitor is used as the vehicle's power output first, and based on the high efficiency of the fuel cell in the low power range, the fuel cell is used as a supplement to the power output.

[0046] Scenario 2: If the required power is greater than the first battery power threshold and less than or equal to the second battery power threshold, the target operating mode is determined to be the battery operating mode.

[0047] Among them, the second battery power threshold This is used to characterize the output power corresponding to the commonly used power efficiency point of the fuel cell. For example, the power demand of the vehicle... satisfy At this time, the output power of the fuel cell can meet the power requirements of the vehicle, and the target operating mode is determined to be the battery working mode, using the fuel cell to output electrical energy to power the vehicle motor.

[0048] Scenario 3: If the required power is greater than the second battery power threshold and less than or equal to the sum of the internal combustion engine power threshold and the second battery power threshold, the target operating mode is determined to be the internal combustion engine operating mode.

[0049] Among them, the power threshold of the internal combustion engine This is used to characterize the efficient operating power value of the hydrogen internal combustion engine. For example, the power demand of the vehicle... satisfy At this time, the output power of the hydrogen internal combustion engine can meet the power requirements of the vehicle. The target operating mode is determined to be the internal combustion engine working mode, and the hydrogen internal combustion engine outputs electrical energy to provide power to the vehicle's motor.

[0050] Case 4: If the required power is greater than the sum of the internal combustion engine power threshold and the second battery power threshold, the target operating mode is determined to be a combined operating mode.

[0051] For example, the power demand of this vehicle satisfy At this time, neither the fuel cell nor the hydrogen internal combustion engine can meet the power requirements of the vehicle when used as a power source alone. It can be determined that the target operating mode is a joint working mode, in which the fuel cell, hydrogen internal combustion engine and supercapacitor simultaneously output electrical energy to the vehicle motor to provide power to the vehicle.

[0052] In some embodiments, the method for determining the target output power in step S13 above may include the following various cases: Case 1: When the target operating mode is idle mode, execute step S1311 or step S1312 according to the value of the first SOC.

[0053] S1311. If the first SOC value is greater than the first energy threshold, the required power is used as the target output power of the supercapacitor, and the preset power value is used as the target output power of the fuel cell and the hydrogen internal combustion engine. In this way, when the vehicle is idling, the fuel cell and the hydrogen internal combustion engine can be put on standby, and the fast charging and discharging rate of the supercapacitor can be used to provide power through the supercapacitor, thereby reducing vehicle energy consumption.

[0054] Among them, the first power threshold This can be the maximum state of charge (SOC) of the supercapacitor, and the preset power value can be 0. For example, at this first SOC value... satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. This is the required power.

[0055] S1312. If the first SOC value is less than or equal to the first energy threshold, the first battery power threshold is used as the target output power of the fuel cell, the preset power value is used as the target output power of the hydrogen internal combustion engine, and the difference between the first battery power threshold and the required power is used as the target output power of the supercapacitor. In this way, when the vehicle is idling and the supercapacitor's state of charge is low, the fuel cell's high efficiency in the low-power range can be utilized to provide power, and the remaining power from the fuel cell output after meeting the vehicle's power requirements can be used to charge the supercapacitor.

[0056] For example, at the first SOC value satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. This is the first battery power threshold. This is the required power.

[0057] Case 2: When the target operating mode is battery operating mode, step S1321 or step S1322 is executed according to the magnitude of the first SOC value.

[0058] S1321. When the first SOC value is greater than the first energy threshold, the current fuel cell power is taken as the target output power of the fuel cell, the preset power value is taken as the target output power of the hydrogen internal combustion engine, and the difference between the required power and the current fuel cell power is taken as the target output power of the supercapacitor. In this way, when the fuel cell is in the high-efficiency range and the supercapacitor has a high state of charge, the fuel cell can maintain its current output power to provide power, while the supercapacitor can supplement the remaining part of the required power.

[0059] Among them, the first power threshold This can be the maximum state of charge (SOC) of the supercapacitor, and the preset power value can be 0. At this first SOC value... satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. For the current fuel cell power, This is the required power.

[0060] S1322. If the first SOC value is less than or equal to the first energy threshold, the required power is used as the target output power of the fuel cell, and the preset power value is used as the target output power of the hydrogen internal combustion engine and the supercapacitor. In this way, the fuel cell can provide power when the fuel cell is in its high-efficiency range and the supercapacitor has a low state of charge, thereby increasing the power drive efficiency.

[0061] For example, at the first SOC value satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. This is the required power.

[0062] Case 3: When the target operating mode is the internal combustion engine working mode, step S1331 or step S1332 is executed according to the magnitude of the first SOC value.

[0063] S1331. When the first SOC value is greater than the first energy threshold, the current fuel cell power is taken as the target output power of the fuel cell, the current internal combustion engine power is taken as the target output power of the hydrogen internal combustion engine, and the difference between the required power and the first sum is taken as the target output power of the supercapacitor. In this way, in the high-efficiency range of the hydrogen internal combustion engine, the hydrogen internal combustion engine maintains its current output power to provide power, the fuel cell maintains its current output power to provide supplementary power, and the supercapacitor supplements the remaining part of the required power.

[0064] Among them, the first power threshold This can be the maximum state of charge (SOC) of the supercapacitor, where the first sum is the sum of the current internal combustion engine power and the current fuel cell power. For example, at this first SOC value... satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. For the current fuel cell power, For this required power, This represents the current power output of the internal combustion engine.

[0065] S1332, If the first SOC value is less than or equal to the first energy threshold, the current fuel cell power is used as the target output power of the fuel cell, the difference between the required power and the current internal combustion engine power is used as the target output power of the hydrogen internal combustion engine, and the preset power value is used as the target output power of the supercapacitor. In this way, the hydrogen internal combustion engine can provide power in the high-efficiency range, while the fuel cell maintains its current output power to supplement the remaining part of the required power.

[0066] The preset power value can be 0. For example, at this first SOC value... satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. For this required power, For the current fuel cell power, This represents the current power output of the internal combustion engine.

[0067] Case 4: When the target operating mode is the joint working mode, one of the steps S1341, S1342 and S1343 shall be executed according to the size of the first SOC value.

[0068] S1341. When the first SOC value is greater than the first energy threshold, the second battery power threshold is used as the target output power of the fuel cell, the current internal combustion engine power is used as the target output power of the hydrogen internal combustion engine, and the difference between the required power and the second sum is used as the target output power of the supercapacitor. In this way, when the vehicle's power demand is high and the remaining energy of the supercapacitor is excessive, power can be provided simultaneously by the fuel cell and the hydrogen internal combustion engine, with the supercapacitor supplementing the remaining power demand, thereby improving the efficiency and reliability of the power drive.

[0069] Among them, the first power threshold This can be the maximum state of charge of the supercapacitor, or the power threshold of the second battery. The second sum, used to characterize the output power corresponding to the commonly used power efficiency point of the fuel cell, is the sum of the second battery power threshold and the current internal combustion engine power. For example, at the first SOC value... satisfy At that time, the target output power is determined as follows: , , ,in The target output power of the fuel cell, This represents the target output power of the hydrogen internal combustion engine. This is the target output power of the supercapacitor. For this required power, This is the power threshold of the second battery.
