DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0021] The hydrogen internal combustion engine control method provided in the embodiment of the present application can be applied to a hydrogen internal combustion engine. The internal system structure diagram of the hydrogen internal combustion engine can be as follows: Figure 1 As shown, the energy storage device is respectively connected to the motor and the electric heating element, and is used to output corresponding driving current to the motor and the electric heating element after receiving the first control instruction issued by the controller; the speed sensor, the water temperature sensor and the oil temperature sensor are all communicatively connected to the controller, and are used to transmit the speed signal, the cooling water temperature signal and the oil temperature signal to the controller respectively, and the controller controls the hydrogen internal combustion engine based on the above signals; the electric heating element is used to heat the cooling water according to the control instruction output by the controller; the hydrogen nozzle is used to spray hydrogen according to the control instruction output by the controller.

[0022] In an exemplary embodiment, Figure 2 As shown, a hydrogen internal combustion engine control method is provided, which is applied to Figure 1 The hydrogen internal combustion engine in FIG. 1 is used as an example to illustrate the method, which includes the following steps 202 to 206.

[0023] Step 202 : Determine a first current value and a second current value based on a preset target speed and operating parameters of the hydrogen internal combustion engine; the operating parameters include the moment of inertia of the hydrogen internal combustion engine, the torque constant of the motor, and the initial temperature of the cooling water pipe of the hydrogen internal combustion engine.

[0024] Exemplarily, the target speed refers to the stable operating speed required to be achieved during the starting phase of the hydrogen internal combustion engine. Optionally, the target speed can be set to twice or more than the idle speed of the hydrogen internal combustion engine. The first current value is used to drive the motor integrated on the flywheel to drive the hydrogen internal combustion engine to increase the speed to the target speed; the second current value is used to drive the electric heating element to heat the cooling water pipe of the hydrogen internal combustion engine. The motor and the flywheel are directly welded and fixed to the crankshaft of the hydrogen internal combustion engine. The motor is a permanent magnet motor rotor, forming an integrated flywheel integrated permanent magnet motor, which replaces the independently arranged mechanical flywheel in the traditional hydrogen internal combustion engine, and realizes the coordinated control of the hydrogen internal combustion engine and the motor. During the starting phase of the hydrogen internal combustion engine, the energy storage device supplies power to the flywheel integrated permanent magnet motor according to the first current value, so as to drive the flywheel integrated permanent magnet motor to rotate the crankshaft of the hydrogen internal combustion engine, thereby driving the hydrogen internal combustion engine to accelerate to the target speed; when the hydrogen internal combustion engine enters the normal operation phase, the crankshaft drives the flywheel integrated permanent magnet motor to operate as a generator, converting mechanical energy into electrical energy, and feeding it back to the energy storage device to realize energy recovery, thereby effectively improving the energy efficiency of the hydrogen internal combustion engine.

[0025] For example, after determining the target speed of the hydrogen internal combustion engine based on its idle speed, the controller obtains preset operating parameters of the hydrogen internal combustion engine, including the engine's moment of inertia, the motor's torque constant, and the initial temperature of the cooling water pipe collected by a water temperature sensor. Based on these parameters, the controller determines a first current value required to drive the motor to accelerate the hydrogen internal combustion engine from rest to the target speed, and a second current value required to drive the electric heating element to heat the cooling water pipe.

[0026] Step 204: Send a first control instruction to the energy storage device; the first control instruction is used to instruct the energy storage device to output a first current value to the motor and to output a second current value to the electric heating element; the motor, driven by the first current value, drives the speed of the hydrogen internal combustion engine to a target speed; the electric heating element, driven by the second current value, heats the cooling water pipe of the hydrogen internal combustion engine.

[0027] For example, please refer again to Figure 1 The energy storage device is connected to the motor and the electric heating element. The energy storage device is used to store the electrical energy generated by the motor during the normal operation of the hydrogen internal combustion engine, and output the corresponding drive current to the motor and the electric heating element according to the first control instruction during the start-up phase of the hydrogen internal combustion engine. The electric heating element is arranged on the surface of the cooling water pipe and contacts the cooling water inside the cooling water pipe through the metal shell of the cooling water pipe, ensuring efficient heat transfer of the electric heating element and achieving rapid heating of the cooling water. The electric heating element can be a resistance wire, a positive temperature coefficient heater (PTC heater), etc.

[0028] The controller generates a first control instruction based on the determined first current value and second current value, and the first control instruction includes an instruction signal for controlling the energy storage device to output the required current to the motor and the electric heating element respectively. Exemplarily, the controller sends the first control instruction to the energy storage device, instructing the energy storage device to output a current of the first current value to the motor, so as to drive the motor to drive the crankshaft of the hydrogen internal combustion engine to rotate, so that the speed of the hydrogen internal combustion engine is gradually increased to the target speed. At the same time, the energy storage device also outputs a current of the second current value to the electric heating element according to the first control instruction, driving the electric heating element to heat the cooling water pipe of the hydrogen internal combustion engine, thereby increasing the cooling water temperature and thereby increasing the temperature of the engine oil.

[0029] Step 206 : When a preset condition is met, the operating state of the hydrogen internal combustion engine is controlled to be a hydrogen injection state; the preset condition includes maintaining the speed of the hydrogen internal combustion engine at a target speed within a preset time.

[0030] The hydrogen injection state of a hydrogen internal combustion engine refers to the fuel supply system (hydrogen nozzle) gradually increasing the amount of hydrogen injected into the combustion chamber according to a linear law until the preset target hydrogen injection amount is reached; after reaching the target hydrogen injection amount, the hydrogen nozzle maintains the target hydrogen injection amount level and continues to inject hydrogen into the combustion chamber.

[0031] After the drive motor drives the crankshaft of the hydrogen internal combustion engine to rotate and the speed of the hydrogen internal combustion engine is increased to the target speed, the speed of the hydrogen internal combustion engine monitored by the speed sensor is obtained in real time; according to preset conditions, it is judged whether the speed of the hydrogen internal combustion engine is stably maintained at the target speed, and when the speed of the hydrogen internal combustion engine continuously maintains the target speed for a preset time, the hydrogen internal combustion engine is controlled to enter the hydrogen injection state, that is, the hydrogen nozzle is started to inject hydrogen into the combustion chamber. This can ensure that the hydrogen internal combustion engine enters the hydrogen injection combustion stage under the condition of stable speed, improve the reliability of the hydrogen internal combustion engine starting stage, and effectively avoid combustion abnormalities.

[0032] In one feasible embodiment, the oil cooler is a heat exchange device that exchanges heat between the engine oil and cooling water in the hydrogen internal combustion engine. The oil cooler includes a controllable electronic thermostat that adjusts the opening of the thermostat valve according to the oil temperature. For example, when the thermostat valve is fully closed, the oil bypasses the oil cooler and circulates directly to the various components of the hydrogen internal combustion engine via a bypass valve. When the thermostat valve is fully open, the oil flows entirely through the cooler, rapidly exchanges heat with the cooling water, and then circulates to the various components of the hydrogen internal combustion engine. A hydrogen nozzle is mounted on the intake manifold of the hydrogen internal combustion engine and is used to inject hydrogen according to control commands output by a controller. Specifically, the controller can control the timing and amount of hydrogen injection from the hydrogen nozzle.

[0033] The speed sensor is located at the motor to detect the speed of the hydrogen internal combustion engine and generate a speed signal for transmission to the controller. The water temperature sensor is installed on the cooling water pipe to monitor the temperature of the cooling water pipe in real time and generate a cooling water temperature signal for transmission to the controller. The oil temperature sensor is installed at the inlet and outlet of the oil pump or oil cooler to monitor the temperature of the oil in real time and generate an oil temperature signal for transmission to the controller. The controller receives signals transmitted by the speed sensor, water temperature sensor, and oil temperature sensor, and controls the hydrogen internal combustion engine based on these signals.

[0034] In this embodiment, based on a preset target speed and operating parameters of the hydrogen internal combustion engine, a first current value and a second current value are determined; a first control instruction is sent to the energy storage device. The first control instruction is used to instruct the energy storage device to output the first current value to the motor. Driven by the first current value, the motor drives the speed of the hydrogen internal combustion engine to the target speed. This can directly increase the speed of the hydrogen internal combustion engine to the high-efficiency operating range (target speed) through the motor drive, avoiding low-speed operation of the hydrogen internal combustion engine and achieving zero-low-speed combustion range of the hydrogen internal combustion engine. Simultaneously, the first control instruction is used to instruct the energy storage device to output the second current value to the electric heating element. Driven by the second current value, the electric heating element heats the cooling water pipe of the hydrogen internal combustion engine. This can heat the cooling water during the startup phase of the hydrogen internal combustion engine, improve oil fluidity, increase cylinder wall temperature, eliminate the condensation window, inhibit water vapor liquefaction, improve the combustion stability of the hydrogen internal combustion engine, and solve the problem of oil emulsification during cold starts of the hydrogen internal combustion engine. Furthermore, when the speed of the hydrogen internal combustion engine is maintained at the target speed within a preset time, controlling the hydrogen internal combustion engine to be in a hydrogen injection state can ensure that the hydrogen injection operation of the hydrogen internal combustion engine is performed after the operating state of the hydrogen internal combustion engine is stable, thereby ensuring the stability and safety of the combustion process, and avoiding abnormal problems such as pre-ignition, backfire, and oil emulsification caused by cold start.

[0035] In an exemplary embodiment, Figure 3 As shown, step 202 includes steps 302 to 306 .

[0036] Step 302 : Determine the target time required for the speed of the hydrogen internal combustion engine to reach the target speed based on the target speed, the moment of inertia, and the torque constant.

[0037] Optionally, the target time required for the hydrogen internal combustion engine to reach the target speed is determined based on the rotational inertia corresponding to different hydrogen internal combustion engines, the torque constant of the motor and the pre-set target speed, combined with manual experience. There is no need to solve complex dynamic equations in real time during the operation of the hydrogen internal combustion engine, which simplifies the control logic and improves the response efficiency and adaptability of the hydrogen internal combustion engine control.

[0038] Step 304 : determining a first current value according to the target speed, the moment of inertia, the torque constant, and the target time.

[0039] A first current value is determined based on the rotational inertia of the hydrogen internal combustion engine, the torque constant of the motor, and the target time required to drive the hydrogen internal combustion engine from a stationary state to a target speed; the first current value is used to drive the motor to increase the speed of the hydrogen internal combustion engine at a fixed angular acceleration, so that the speed of the hydrogen internal combustion engine is increased to the target speed within the target time.

[0040] Step 306 : Determine a second current value according to the initial temperature, the target temperature of the cooling water pipe, and the target time.

[0041] For example, the initial temperature of the cooling water pipe of the hydrogen internal combustion engine is obtained, which can be obtained by a water temperature sensor installed on the cooling water pipe. A target temperature of the cooling water pipe during the startup phase of the hydrogen internal combustion engine is pre-set based on actual conditions. Based on the initial temperature, the target temperature, and the target time, a second current value required to increase the cooling water temperature in the cooling water pipe from the initial temperature to the target temperature within the target time is calculated.

[0042] In this embodiment, the target time required for the hydrogen internal combustion engine to reach the target speed is determined based on the target speed, rotational inertia, and torque constant of the motor, facilitating dynamic adaptation of the starting characteristics of different hydrogen internal combustion engine models. Furthermore, based on this target time, a first current value required to drive the motor and a second current value required to drive the electric heating element are determined, respectively. This ensures that the dynamic response of the hydrogen internal combustion engine during the starting phase (i.e., the process of driving the hydrogen internal combustion engine to the target speed) is coordinated with the temperature rise of the cooling water. This not only ensures that the hydrogen internal combustion engine stably reaches the target speed within the target time, but also effectively preheats the engine oil through the simultaneous increase in cooling water temperature, reducing the risk of oil emulsification during cold start conditions and improving the reliability and environmental adaptability of the hydrogen internal combustion engine.

[0043] In an exemplary embodiment, Figure 4 As shown, step 304 includes steps 402 to 406 .

[0044] Step 402: Determine a first parameter according to the product of the moment of inertia and the target speed.

[0045] For example, the moment of inertia of the hydrogen internal combustion engine is J, and the torque constant of the motor is , is the current value output from the energy storage device to the motor, the speed N of the hydrogen internal combustion engine reaches the target speed N The required target time t is related to: .

[0046] Reach target speed and target speed The relationship between the required target time t is: .

[0047] According to the above formula, the first parameter is .

[0048] Step 404: Determine a second parameter based on the product of the torque constant and the target time.

[0049] Based on the above, the second parameter determined by the product of the torque constant and the target time is .

[0050] Step 406: Determine a first current value according to the ratio of the first parameter to the second parameter.

[0051] The first parameter and the second parameter Perform ratio processing to obtain the first current value: .

[0052] When the controller receives the start signal of the hydrogen internal combustion engine, it controls the energy storage device to output the first current value The current is used to drive the motor to increase the speed at a fixed angular acceleration so that the target time Increase the speed N of the hydrogen internal combustion engine to the target speed .

[0053] In this embodiment, a first parameter is obtained by multiplying the moment of inertia of the hydrogen internal combustion engine by the target speed, and a second parameter is obtained by multiplying the torque constant of the motor by the target time, and the first current value is determined by the ratio of the two. This provides a structured and quantifiable solution method for the first current value, thereby achieving rapid determination of the motor drive current. At the same time, this embodiment can be applied to scenarios where parameters in hydrogen internal combustion engine systems of different models differ, thereby improving the scalability of hydrogen internal combustion engine control.

[0054] In an exemplary embodiment, Figure 5 As shown, step 306 includes steps 502 to 506 .

[0055] Step 502: Determine the difference between the target temperature and the initial temperature as the temperature difference.

[0056] The initial temperature of the cooling water pipe of the hydrogen internal combustion engine is obtained according to the water temperature sensor installed on the cooling water pipe , and pre-set the target temperature of the cooling water pipe during the start-up phase of the hydrogen internal combustion engine based on actual conditions For example, the target temperature of the cooling water pipe can be Set to 90 degrees Celsius. Calculate the difference between the target temperature and the initial temperature, and the temperature difference is .

[0057] Step 504: Determine the time difference according to the temperature difference and the preset coefficient.

[0058] Exemplarily, the preset coefficient k is: Sure.

[0059] In the above formula, is the total mass of cooling water in the hydrogen internal combustion engine, c is the specific heat capacity of cooling water, R is the resistance value of the electric heating element, is the heating efficiency of converting electrical energy into cooling water heat energy; since the structure of the hydrogen internal combustion engine is fixed during its operation, the parameters m, c and R are fixed values, that is, the parameters m, c and R can be obtained by measuring the initial temperature of the cooling water in the bench test of the hydrogen internal combustion engine. After different heating times, the final Confirmed.

[0060] According to the temperature difference and preset coefficients , determine the time difference as .

[0061] Step 506: Determine a second current value according to the ratio of the time difference to the target time.

[0062] The time difference and target time Perform ratio processing to obtain the second current value for: .

[0063] When the controller receives the start signal of the hydrogen internal combustion engine, it controls the energy storage device to output the second current value The current is used to drive the electric heating element to heat the cooling water pipe of the hydrogen internal combustion engine.

[0064] In a feasible embodiment, based on the second current value During the cooling water heating process, the current temperature of the engine oil is obtained; when the difference between the current temperature of the engine oil and the target engine oil temperature is greater than a temperature threshold, the cooling water is controlled to heat the engine oil.

[0065] The current temperature of the oil in the hydrogen internal combustion engine is obtained, and the current temperature of the oil can be obtained according to an oil temperature sensor provided at the inlet and outlet of the oil pump or the oil cooler.

[0066] The current temperature of the oil in the hydrogen internal combustion engine is obtained through the oil temperature sensor installed at the inlet and outlet of the oil pump or oil cooler. Based on the actual working conditions, the target oil temperature for the start-up phase of the hydrogen internal combustion engine is pre-set. The collected current oil temperature is compared with the target oil temperature, and the temperature difference between the two is calculated. When the temperature difference exceeds the preset temperature threshold, the controllable electronic thermostat of the hydrogen internal combustion engine is controlled to be fully open to achieve maximum heat exchange efficiency between the cooling water and the oil. Through this control, the cooling water can quickly transfer heat to the oil, achieving rapid heating of the oil. The heating process continues until the preset conditions for stopping heating are met, thereby effectively preventing the performance degradation of the oil at low temperatures and the emulsification of the oil, thereby ensuring the operating safety and reliability of the hydrogen internal combustion engine.

[0067] Optionally, the preset condition for stopping heating is that the hydrogen internal combustion engine has completed the startup phase and the difference between the current temperature of the engine oil and the target engine oil temperature is less than a temperature threshold. The termination of the startup phase of the hydrogen internal combustion engine refers to the real-time hydrogen injection amount of the hydrogen internal combustion engine reaching the target hydrogen injection amount of the hydrogen internal combustion engine, the first current value is reduced to a preset value, and the real-time speed of the hydrogen internal combustion engine is maintained at the target speed. When the preset condition for stopping heating is met, it is determined that the hydrogen internal combustion engine has entered a normal combustion state. At this time, the controllable electronic thermostat is switched to a normal operating mode, that is, the opening of the controllable electronic thermostat is automatically adjusted according to the current temperature of the engine oil to ensure that the engine oil temperature is maintained within a reasonable range.

[0068] In this embodiment, by setting the difference between the target temperature and the initial temperature as the temperature difference, and calculating the time difference based on the temperature difference and the preset coefficient, the time difference is further ratio-calculated with the target time to determine the second current value, the working current of the electric heating element can be adjusted according to the actual temperature rise requirement and the allowed time length of the hydrogen internal combustion engine starting phase, so that the temperature of the cooling water pipe can reach the ideal state within the preset time window, ensuring that the hydrogen internal combustion engine has a suitable thermal environment before entering the hydrogen injection phase, which can effectively reduce the risk of oil emulsification and cold start energy consumption, and improve the reliability, energy efficiency and adaptability of the hydrogen internal combustion engine.

[0069] In an exemplary embodiment, the method further includes: after controlling the hydrogen internal combustion engine to be in a hydrogen injection state, controlling the real-time hydrogen injection amount of the hydrogen internal combustion engine to increase linearly until the real-time hydrogen injection amount of the hydrogen internal combustion engine is the target hydrogen injection amount, and adjusting the first current value according to the current adjustment step until the first current value is a preset value.

[0070] In some feasible embodiments, the preset value may be set to 0.

[0071] During the period when the hydrogen internal combustion engine is in the hydrogen injection state, the controller dynamically adjusts the first current value. For example, as the hydrogen injection process of the hydrogen internal combustion engine continues to advance, the first current value is controlled to decrease in inverse proportion based on the current adjustment step. In the process of the real-time hydrogen injection amount of the hydrogen internal combustion engine increasing in a linear manner, the first current value is synchronously adjusted so that it decreases in inverse proportion with the increase of the hydrogen injection amount until the first current value decreases to zero. Optionally, as Figure 6 As shown, it is a schematic diagram of the dynamic adjustment of the first current and the real-time hydrogen injection amount. The controller controls the energy storage device to output a driving current of the first current value to the motor to drive the speed of the hydrogen internal combustion engine to increase. When the target time t is reached, the controller controls the hydrogen internal combustion engine to enter the hydrogen injection state and controls the hydrogen nozzle to continuously inject hydrogen into the combustion chamber, so that the real-time hydrogen injection amount gradually increases according to the linear law until the target hydrogen injection amount is reached. In the process of the above-mentioned real-time hydrogen injection amount gradually increasing according to the linear law, the controller dynamically adjusts the first current value based on the current adjustment step size, so that it gradually decreases according to the inverse proportional law. Through this dynamic adjustment process of the first current value, the motor can smoothly exit the driving effect of the hydrogen internal combustion engine, ensuring that the transition process from electric drive to combustion drive is without mutation, and improving the stability and response consistency of the system operation during the starting phase.

[0072] In this embodiment, after the hydrogen internal combustion engine enters the hydrogen injection state, the first current value is dynamically adjusted according to the current adjustment step size until the first current value reaches zero. This achieves a smooth transition from motor drive to hydrogen combustion drive, avoiding instability caused by sudden changes in motor output current and effectively maintaining the stability of the hydrogen internal combustion engine. Furthermore, as the amount of hydrogen injected gradually increases, the motor drive effect proportionally decreases, reducing power consumption, extending the service life of the energy storage device and motor, and improving the energy efficiency and reliability of the hydrogen internal combustion engine system.

[0073] In an exemplary embodiment, Figure 7 As shown, the process of determining the current adjustment step size includes steps 702 to 704 .

[0074] Step 702: Determine the real-time hydrogen injection amount of the hydrogen internal combustion engine.

[0075] For example, when the hydrogen internal combustion engine is in the hydrogen injection state, the real-time hydrogen injection amount of the hydrogen internal combustion engine gradually increases according to a linear law until the hydrogen internal combustion engine reaches the target speed. Under this condition, its output torque reaches the target torque required to maintain stable operation At this time, the corresponding hydrogen injection amount is the target hydrogen injection amount . Specifically, Figure 8 The diagram shows the change of the real-time speed and output torque of the hydrogen internal combustion engine. When the real-time speed of the hydrogen internal combustion engine is 0, its output torque is 0. As the motor drives the real-time speed N of the hydrogen internal combustion engine to gradually increase and stabilize to the target speed , control the hydrogen internal combustion engine to enter the hydrogen injection state, the hydrogen nozzle continuously injects hydrogen into the combustion chamber, so that the output torque of the hydrogen internal combustion engine gradually increases until it reaches the target torque The real-time hydrogen injection amount at this time is the target hydrogen injection amount. The above real-time hydrogen injection amount is .

[0076] in, is the cumulative hydrogen injection time at the current moment, is a fixed hydrogen injection rate coefficient confirmed based on bench tests.

[0077] Step 704 : Determine the current adjustment step size according to the product value of the real-time hydrogen injection amount and the current adjustment coefficient.

[0078] The current adjustment coefficient is determined according to the ratio of the first current value to the target hydrogen injection amount. for .

[0079] In the above formula, The target hydrogen injection amount is the hydrogen injection amount required for the hydrogen internal combustion engine to achieve the target torque at the target speed. is the first current value.

[0080] The current adjustment step is obtained by multiplying the real-time hydrogen injection amount and the current adjustment coefficient. .

[0081] In one embodiment, as the hydrogen injection process of the hydrogen internal combustion engine continues to advance, the step size is adjusted based on the current. Control the first current value The process of decreasing in inverse proportion can be expressed as .

[0082] In this embodiment, after the hydrogen internal combustion engine is in the hydrogen injection state, the first current value is dynamically adjusted based on the real-time hydrogen injection amount of the hydrogen internal combustion engine, and the current adjustment coefficient is determined based on the proportional relationship between the first current value and the target hydrogen injection amount, and then the current adjustment step is calculated, so that when the real-time hydrogen injection amount increases, the driving current of the motor (the first current value) is synchronously reduced. ), which can ensure the constant speed of the hydrogen internal combustion engine, thereby achieving a precise and smooth transition from motor drive to hydrogen combustion drive. At the same time, by using the ratio of the first current value of the hydrogen internal combustion engine to the target hydrogen injection amount as the basis for the current adjustment coefficient, the adjustment rhythm can be dynamically and adaptively adjusted for different types of hydrogen internal combustion engines (such as different rotational inertia or load characteristics), thereby improving the universality of control.

[0083] In an exemplary embodiment, the method further includes: if the hydrogen internal combustion engine is in a hydrogen injection state and the real-time speed of the hydrogen internal combustion engine is less than the target speed, sending a second control instruction to the energy storage device; the second control instruction is used to instruct the energy storage device to adjust the current output current value to the first current value.

[0084] During the period when the hydrogen internal combustion engine is in the hydrogen injection state, in the process of adjusting the first current value according to the current adjustment step, the real-time speed of the hydrogen internal combustion engine is obtained in real time through the speed sensor, and the compensation control process is determined based on the real-time speed and the target speed. Specifically, the real-time speed is compared with the target speed. When it is detected that the real-time speed of the hydrogen internal combustion engine is lower than the target speed, it indicates that the driving force provided by the hydrogen combustion is insufficient to maintain a stable operating state. At this time, the controller generates a second control instruction and sends it to the energy storage device. The second control instruction is used to instruct the energy storage device to increase the current value currently output to the motor to the first current value to assist the hydrogen internal combustion engine in increasing the speed to the target speed. After assisting the hydrogen internal combustion engine in increasing the real-time speed to the target speed, return to the above-mentioned compensation control process and continue to adjust the first current value based on the current adjustment step. For example, when the first current value is adjusted according to the current adjustment step. , so that the first current value Reduce to When it is detected that the real-time speed of the hydrogen internal combustion engine is lower than the target speed, the controller controls the energy storage device to increase the current value currently output to the motor to the first current value , to assist the hydrogen internal combustion engine to increase the real-time speed to the target speed; and after assisting the hydrogen internal combustion engine to increase the real-time speed to the target speed, continue to adjust the current step size to Make adjustments.

[0085] In this embodiment, the compensation control process determined based on the real-time speed and the target speed has an adaptive closed-loop adjustment capability, and can promptly restore the stability of the hydrogen internal combustion engine speed in the event of load disturbances, unstable combustion, or changes in ambient temperature during the hydrogen injection process, thereby ensuring the smoothness of the entire hydrogen injection transition process and the reliability of the system operation.
