Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0049] Figure 1 is a schematic connection diagram of a supercharging system for a hydrogen engine provided according to an embodiment of the present invention. As Figure 1As shown in the figure, the supercharging system of the hydrogen engine includes: an exhaust gas turbine 10, a drive motor 20, a pressure wheel 30, a mechanical transmission assembly 40, and a control unit 60; the pressure wheel 30 is communicated with the engine intake port; the exhaust gas turbine 10 is communicated with the engine exhaust port; the drive motor 20 is respectively connected with the exhaust gas turbine 10 and the pressure wheel 30 through an intermediate shaft; the mechanical transmission assembly 40 is respectively connected with the engine crankshaft and the pressure wheel 30; the control unit is respectively communicatively connected with the engine 60, the exhaust gas turbine 10, the drive motor 20, and the mechanical transmission assembly 40. Among them, the exhaust gas turbine 10 is communicated with the engine exhaust port, and can receive the exhaust gas of the engine to provide kinetic energy for the exhaust gas turbine 10. The drive motor 20 is respectively connected with the exhaust gas turbine 10 and the pressure wheel 30 through an intermediate shaft. When the waste turbine rotates, it can drive the pressure wheel 30 to rotate through the intermediate shaft, and then provide air for the engine intake port. Similarly, when the drive motor 20 starts, it can also drive the pressure wheel 30 to rotate through the intermediate shaft, and then provide air for the engine intake port. Similarly, by connecting the engine crankshaft with the mechanical transmission assembly 40 and controlling the mechanical transmission assembly 40, the pressure wheel 30 can also be driven to rotate to provide air for the engine intake port.

[0050] It can be understood that the exhaust gas turbine 10 drive, the mechanical transmission drive, and the drive motor 20 drive are three different driving modes under different working conditions, aiming to solve the problem of poor transient power performance of the hydrogen engine and ensure that sufficient air is provided for the hydrogen engine under transient working conditions. Figure 2 It is a flowchart of the first control method of the hydrogen engine provided by the embodiment of the present invention. The specific control method is as Figure 1 shown, and the control method includes:

[0051] S10. Obtain the engine speed and engine torque.

[0052] Among them, both the engine speed and the engine torque are obtained in real time. The engine speed can be measured by a sensor of a signal disk installed on the crankshaft. The engine torque can be obtained by calculation or directly measured, and the embodiment of the present invention does not limit this.

[0053] S11. Under the transient working condition of the engine, determine the operating area of the engine according to the engine speed and the engine torque.

[0054] Among them, the transient working condition of the engine can be the acceleration working condition of the engine. The hydrogen engine has a large air demand and poor transient performance under transient working conditions. In the embodiment of the present invention, the engine speed and the engine torque are obtained in real time, and the current operating area of the engine is determined according to the engine speed and the engine torque. Among them, the operating area can characterize the size of the engine load. Control the operating states of different components in the supercharging system according to the size of the engine load.

[0055] In some embodiments, the operating regions may include a first operating region A, a second operating region B, and a third operating region C. The first operating region A may be a low-load state of the engine, with corresponding engine speed and engine torque. Figure 3 is a schematic diagram of the division of the operating regions of a hydrogen engine provided according to an embodiment of the present invention, as Figure 3 shown, the engine torque in the first operating region A is relatively small; the second operating region B may be a medium-load state of the engine, with corresponding engine speed and engine torque. As shown in the figure; the third operating region C may be a high-load state of the engine, with corresponding engine speed and engine torque, as shown in the figure. The engine loads in different operating regions are different, and thus different supercharging methods are selected to ensure that the engine intake port receives air in a timely manner, thereby improving the transient kinetic energy of the engine.

[0056] S12. Control the drive motor, the mechanical transmission assembly, or the exhaust gas turbine according to the operating region.

[0057] Among them, the drive motor 20, the mechanical transmission assembly, and the exhaust gas turbine 10 respectively correspond to different supercharging methods, ensuring that different air demands can be provided for the engine in different operating regions, effectively solving the problem of poor transient dynamic performance, improving the transient dynamic performance of the hydrogen internal combustion engine, and achieving efficient and clean application.

[0058] The technical solution of the embodiment of the present invention effectively solves the problem of poor transient dynamic performance, improves the transient dynamic performance of the hydrogen internal combustion engine, and achieves efficient and clean application by obtaining the engine speed and engine torque in real time, judging the engine operating region, and determining different supercharging methods by using the exhaust gas turbine, the drive motor, and the mechanical transmission assembly according to the operating region of the hydrogen engine.

[0059] Based on the above embodiments, Figure 4 is a flowchart of a second control method for a hydrogen engine provided according to an embodiment of the present invention. Combining Figure 1 、 Figure 2 and Figure 4 shown, the operating region includes a first operating region A. The control method includes:

[0060] S20. Obtain the engine speed and engine torque.

[0061] S21. Determine the operating region of the engine according to the engine speed and engine torque under the transient condition of the engine.

[0062] S22. When the engine torque and engine speed are in the first operating region, control the drive motor to start so that the drive motor drives the pressure wheel to rotate.

[0063] Among them, the first operating region A can be the low-load state of the hydrogen engine. When the hydrogen engine is under low load, the exhaust gas energy is insufficient, the crankshaft torque is low. At this time, the control drives the motor 20 to start, and only the drive motor 20 is used to drive the pressure wheel 30 to rotate. The supercharging system responds quickly, and then timely provides the required air for the hydrogen engine.

[0064] Exemplarily, referring to Figure 2 the acceleration condition 1 in, the starting point and the ending point of the acceleration condition 1 in the figure are both within the first operating region A. Therefore, under the condition of the acceleration condition 1, the drive motor 20 is always turned on to provide air for the engine in a timely manner.

[0065] In the technical solution of the embodiment of the present invention, when the engine is in the first operating region, the engine is in a low-load state. At this time, the drive motor is started, and the drive motor drives the pressure wheel to rotate, and then timely provides the required air for the hydrogen engine to ensure the transient performance of the hydrogen engine.

[0066] Based on the above embodiment, Figure 5 is a flowchart of a third control method for a hydrogen engine provided according to an embodiment of the present invention. Combining Figure 1 、 Figure 2 and Figure 5 shown, the operating region includes a second operating region B. The control method includes:

[0067] S30. Obtain the engine speed and engine torque.

[0068] S31. In the transient condition of the engine, determine the operating region of the engine according to the engine speed and engine torque.

[0069] S32. When the engine torque and engine speed are in the second operating region, control the mechanical transmission assembly to drive the pressure wheel to rotate.

[0070] Among them, the second operating region B can be the medium-load state of the hydrogen engine. When the load of the hydrogen engine is within a medium range, the exhaust gas energy is still insufficient, and the power consumption of the motor drive is relatively large. At this time, only the mechanical transmission assembly 40 is used to drive the pressure wheel 30, and the supercharging system responds quickly, and then timely provides the required air for the hydrogen engine.

[0071] Exemplarily, referring to Figure 2 the acceleration condition 2 in, Figure 2 the starting point and the ending point of the acceleration condition 2 in are both within the second operating region B. Therefore, under the condition of the acceleration condition 2, only the mechanical transmission assembly 40 is always used for transmission to provide air for the engine in a timely manner.

[0072] In the technical solution of the embodiment of the present invention, when the engine is in the second operating region, the engine is in a medium load state. At this time, the mechanical transmission assembly is started, and the mechanical transmission assembly drives the pressing wheel to rotate, thereby timely providing the required air for the hydrogen engine and ensuring the transient performance of the hydrogen engine.

[0073] Based on the above embodiment, Figure 6 is a flowchart of the fourth control method for a hydrogen engine provided according to an embodiment of the present invention. With reference to Figure 1 、 Figure 2 and Figure 6 shown, the operating region includes a third operating region C; the control method includes:

[0074] S40. Obtain the engine speed and engine torque.

[0075] S41. In the transient condition of the engine, determine the operating region of the engine according to the engine speed and engine torque.

[0076] S42. When the engine torque and engine speed are in the third operating region, control the exhaust gas turbine to drive the pressing wheel to rotate.

[0077] Among them, the third operating region C can be the high load state of the hydrogen engine. The hydrogen engine has a high load, and the energy of the exhaust gas discharged is sufficient to provide the ability to drive the pressing wheel 30. At this time, only the exhaust gas turbine 10 is used to drive the pressing wheel 30, thereby timely providing the required air for the hydrogen engine, recovering the exhaust gas energy, and improving the engine efficiency.

[0078] Exemplarily, referring to Figure 2 for the acceleration condition 3, Figure 2 both the starting point and the ending point of the acceleration condition 3 in it are within the third operating region C. Therefore, under the condition of the acceleration condition 3, only the exhaust gas turbine 10 is always used to drive the pressing wheel 30 to provide air for the engine in a timely manner.

[0079] Continuing to refer to Figure 2 for the acceleration condition 4, the starting point of the acceleration condition 4 in the figure is in the first operating region A, and the ending point is in the second operating region B. Then, first control the driving motor 20 to start. After the engine condition enters the second operating region B, turn off the driving motor 20 and use the mechanical transmission assembly 40 to drive to ensure the transient kinetic energy of the hydrogen engine under the acceleration condition and provide air for the engine in a timely manner.

[0080] Continuing to refer to Figure 2 for the acceleration condition 5, the starting point of the acceleration condition 5 in the figure is in the second operating region B, and the ending point is in the third operating region C. Then, first use the mechanical transmission assembly 40 to drive. After the engine condition enters the third operating region C, use the exhaust gas turbine 10 to drive to ensure the transient kinetic energy of the hydrogen engine under the acceleration condition and provide air for the engine in a timely manner.

[0081] Continue to refer to Figure 2 In acceleration condition 6 in Figure 2 , the starting point of acceleration condition 6 in the figure is in the first operating region A, passes through the second operating region B in the middle, and the end point is in the third operating region C. Then, first control the driving motor 20 to start. After the engine condition enters the second operating region B, turn off the driving motor 20 and drive it using the mechanical transmission assembly 40. After the engine condition enters the third operating region C, drive it using the exhaust gas turbine 10 to ensure the transient kinetic energy under the acceleration condition of the hydrogen engine and provide air for the engine in a timely manner.

[0082] It can be understood that the engine speed and engine torque in the embodiments of the present invention are collected in real time, and thus the engine condition can be judged in real time. Furthermore, different supercharging modes can be switched in a timely manner according to the operating region of the engine condition to ensure that the required air is provided for the engine in a timely manner.

[0083] In the technical solution of the embodiments of the present invention, when the engine is in the third operating region, the engine is in a high-load state. At this time, the exhaust gas turbine is used to drive the pressure wheel to rotate, so as to provide the required air for the hydrogen engine in a timely manner, ensure the transient performance of the hydrogen engine, and improve the engine efficiency.

[0084] On the basis of the above embodiments, Figure 7 is a flowchart of the fifth control method for a hydrogen engine provided according to the embodiments of the present invention. Combining Figure 1 、 Figure 2 and Figure 7 as shown, the control method includes:

[0085] S50. Obtain the engine speed and engine torque.

[0086] S51. Determine the real-time change rate according to the engine speed and engine torque. Among them, the relationship between the engine speed N, the engine torque T, and the real-time change rate r satisfies

[0087] Among them, the real-time change rate can characterize the change of the engine speed and engine torque. Whether the current engine is in a transient condition can be judged through this real-time change rate. By collecting the engine speed and engine torque at continuous time, the real-time change rate can be calculated.

[0088] S52. When the real-time change rate is greater than the change rate threshold, determine that the engine is in the engine transient condition.

[0089] Among them, the change rate threshold can be the maximum value when the engine is in the steady state condition. When the real-time change rate is greater than the change rate threshold, the engine enters the transient condition, and then continue to determine the operating region of the engine transient condition.

[0090] S53. Determine the operating region of the engine based on the engine speed and engine torque.

[0091] S54. Control the drive motor, mechanical transmission assembly, or exhaust gas turbine according to the operating region.

[0092] The technical solution of the embodiment of the present invention accurately judges the operating condition of the engine by determining the real-time change rate according to the engine speed and engine torque, and further ensures the accurate function and normal operation of the supercharging system.

[0093] On the basis of the above embodiment, Figure 8 is a flowchart of the sixth control method for a hydrogen engine provided according to an embodiment of the present invention. With reference to Figure 1 、 Figure 2 and Figure 8 as shown, the control method includes:

[0094] S60. Obtain the engine speed and engine torque.

[0095] S61. Determine the real-time change rate according to the engine speed and engine torque. Among them, the engine speed N, engine torque T, and real-time change rate r satisfy

[0096] S62. When the real-time change rate is greater than the change rate threshold, it is determined that the engine is in the engine transient condition.

[0097] S63. Determine the operating region of the engine based on the engine speed and engine torque.

[0098] S64. Control the drive motor, mechanical transmission assembly, or exhaust gas turbine according to the operating region.

[0099] S65. When the real-time change rate is less than or equal to the change rate threshold, it is determined that the engine is in the engine steady-state condition.

[0100] S66. Control the exhaust gas turbine to drive the pressure wheel to rotate.

[0101] Among them, when the real-time change rate is less than or equal to the change rate threshold, the engine is in the steady-state condition at this time. The air demand is small in the steady-state condition, and only the exhaust gas turbine 10 operates in the supercharging system to ensure the normal operation of the hydrogen engine.

[0102] The technical solution of the embodiment of the present invention determines that the engine is in the engine steady-state condition when the real-time change rate is less than or equal to the change rate threshold, and controls the exhaust gas turbine to drive the pressure wheel to rotate to ensure the normal operation of the hydrogen engine.

[0103] Based on the same inventive concept, Figure 9The figure is a schematic connection diagram of a control device for a hydrogen engine according to an embodiment of the present invention. As Figure 9 shown, an embodiment of the present invention provides a control device for a hydrogen engine, which is used to execute a control method for a hydrogen engine. The control device for the hydrogen engine includes:

[0104] A parameter acquisition module 100, configured to acquire the engine speed and engine torque;

[0105] An operating region determination module 200, configured to determine the operating region of the engine according to the engine speed and engine torque under transient engine conditions;

[0106] An intake air quantity control module 300, configured to control a drive motor, a mechanical transmission component, or an exhaust gas turbine according to the operating region.

[0107] Specifically, first, the parameter acquisition module 100 is used to acquire the engine speed and engine torque; under transient engine conditions, the operating region determination module 200 is then used to determine the operating region of the engine according to the engine speed and engine torque; and then the intake air quantity control module 300 is used to control the drive motor, the mechanical transmission component, or the exhaust gas turbine according to the operating region.

[0108] The technical solution of the embodiment of the present invention, through the coordinated operation of the parameter acquisition module, the operating region determination module, and the intake air quantity control module, and determining different supercharging methods according to the operating region of the hydrogen engine, effectively solves the problem of poor transient power performance, improves the transient power performance of the hydrogen internal combustion engine, and realizes efficient and clean application.
