[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] During the compression process of the engine, as the piston moves upward, the temperature of the combustible mixture in the cylinder gradually increases. At the same time, the combustion particles, spark plug hot spots, and metal spurs remaining in the cylinder as hot spots continue to heat up, and eventually ignite the hydrogen before the spark plug discharges, which is called pre-ignition. Pre-ignition generally occurs when the engine is under high load, accompanied by a sudden explosion sound, power drop and engine overheating, and severe engine damage. Studies have shown that ignition energy can significantly affect the combustion rate of hydrogen. Since the minimum ignition energy of hydrogen is 1 / 10 of that of gasoline, the energy stored in the ignition coil cannot be completely consumed during the spark plug breakdown discharge stage, and the excess energy will be stored in the ignition coil, which is likely to cause abnormal discharge of the ignition coil in the next cycle, thereby causing pre-ignition or backfire.

[0034] In order to solve the above problem, in one embodiment, as shown in FIG1 , a vehicle driving control method is provided. This embodiment takes the method applied to a terminal as an example for explanation. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0035] S102: For a vehicle equipped with a hydrogen engine, the engine load of the vehicle is obtained in real time during the driving process of the vehicle. A variable resistor is connected in parallel to the high-voltage coil in the ignition coil of the hydrogen engine.

[0036] Among them, the variable resistor is used to consume excess ignition energy, thereby suppressing pre-ignition or backfire caused by abnormal discharge of the ignition coil; since the working fluid in the cylinder of a hydrogen engine under different engine loads is different, the insulation resistance in the spark plug discharge electrode is different, so under different working conditions, the resistance value of the resistor in parallel with the high-voltage coil also needs to be different, because if the resistance value of the parallel resistor is too low, the ignition energy will all leak from the parallel resistor end, resulting in the working fluid in the combustion chamber cannot be ignited normally, if the resistance value of the parallel resistor is too high, the residual energy in the ignition coil cannot be consumed by the parallel resistor, which will still cause pre-ignition or backfire, therefore, in this embodiment, the high-voltage coil is connected in parallel with a variable resistor, and the resistance value of the variable resistor is adjusted according to the requirements of different working conditions.

[0037] S104: Based on the engine load, adjust the resistance value of the variable resistor to adjust the ignition strategy of the hydrogen engine.

[0038] Among them, the ignition strategy refers to a series of operations by which the engine control system achieves effective combustion of hydrogen in the engine cylinder by controlling parameters such as ignition timing, ignition energy and ignition mode according to the engine's operating state and external conditions; the resistance value adjustment method of the variable resistor can be but is not limited to adjustment by a sliding rheostat, thermal sensitive adjustment or pressure sensitive adjustment.

[0039] S106: Control vehicle driving based on the ignition strategy.

[0040] Among them, based on the ignition strategy, sufficient spark is generated by the spark plug at the right time to ignite the mixed gas, thereby driving the hydrogen engine to work.

[0041] In the above vehicle driving control method, for a vehicle equipped with a hydrogen engine, during the driving process of the vehicle, the engine load of the vehicle is obtained in real time, and a variable resistor is connected in parallel to the high-voltage coil in the ignition coil of the hydrogen engine; based on the engine load, the resistance value of the variable resistor is adjusted to adjust the ignition strategy of the hydrogen engine; and the vehicle driving is controlled based on the ignition strategy. The method provided in this application can effectively avoid the problem of pre-ignition or backfire in the hydrogen engine.

[0042] In some embodiments, as shown in FIG2 , obtaining the engine load of the vehicle in real time includes:

[0043] S202: Acquire the engine speed, throttle opening, and engine torque of the vehicle in real time.

[0044] S204: Obtain engine load based on engine speed, throttle opening, and engine torque.

[0045] Among them, engine load refers to the workload that the engine bears during operation. It is related to the engine's output power and the amount of hydrogen consumed. The engine load can be estimated based on parameters such as engine speed, throttle opening and engine torque.

[0046] In this embodiment, the engine load is obtained based on the engine speed, the throttle opening and the engine torque, so that the obtained engine load is more accurate.

[0047] In some embodiments, the variable resistor corresponds to multiple preset resistance values, each preset resistance value corresponds to a preset load range; based on the engine load, the resistance value of the variable resistor is adjusted, including: determining the preset load range in which the engine load is located as the target load range; obtaining the target resistance value corresponding to the target load range from the multiple preset resistance values; and adjusting the resistance value of the variable resistor to the target resistance value.

[0048] Optionally, for example, there are three preset load ranges, which are less than 30%, greater than or equal to 30% and less than 70%, and greater than or equal to 70%.

[0049] In this embodiment, the resistance value of the variable resistor is adjusted based on the corresponding relationship between the preset resistance value and the preset load range, so that the adjustment result of the resistance value of the variable resistor is more accurate.

[0050] In some embodiments, there is a positive correlation between the resistance value and the engine load.

[0051] Optionally, for example, the preset resistance value corresponding to the preset load range less than 30% is the smallest, the preset resistance value corresponding to the preset load range greater than or equal to 30% and less than 70% is in the middle, and the preset resistance value corresponding to the preset load range greater than or equal to 70% is the largest.

[0052] In this embodiment, there is a positive correlation between the resistance value and the engine load, so that the adjustment result of adjusting the resistance value of the variable resistor based on the engine load is more accurate.

[0053] In some embodiments, the ignition coil includes a high-voltage coil, a low-voltage coil and an iron core. One end of the high-voltage coil is connected to the spark plug, and the other end is connected to the vehicle body ground. One end of the low-voltage coil is connected to the power supply, and the other end is connected to the ignition control unit or the breaker.

[0054] In some embodiments, the ignition strategy includes hydrogen and oxygen mixture ratio control, ignition timing control, load matching, energy management, temperature control, and pressure control.

[0055] Among them, energy management refers to the efficient use of the energy generated by hydrogen combustion by optimizing ignition strategies and control technologies to improve the overall performance and fuel economy of the engine; load matching refers to adjusting the ignition timing and ignition energy according to the real-time load conditions of the engine to ensure that the engine can operate efficiently and stably under different working conditions.

[0056] In this embodiment, the driving process of the vehicle is controlled based on these ignition strategies, so that the driving process of the vehicle is cleaner and more energy-efficient.

[0057] In one embodiment, as shown in FIG3 , another vehicle driving control method is provided, the method comprising the following contents:

[0058] This embodiment provides a method of consuming excess ignition energy by connecting a dissipative resistor in parallel in the ignition coil, thereby suppressing premature ignition or flashback caused by abnormal discharge of the ignition coil. Since the working fluid in the cylinder of the engine under different loads is different, the insulation resistance in the spark plug discharge electrode is different. Therefore, under different working conditions, the high-voltage coil of the ignition coil needs to be connected in parallel with different resistors. If the parallel resistance is too low, the ignition energy will all leak from the parallel resistance end, causing the working fluid in the combustion chamber to fail to be ignited normally. If the parallel resistance is too high, the residual energy in the ignition coil cannot be consumed through the parallel resistance, still causing premature ignition or flashback.

[0059] During vehicle operation, the system determines the engine load at this time by reading the engine speed, throttle opening, torque and other information transmitted by the ECU. When the system determines that the current engine load is less than 30%, at this time, due to the small amount of working fluid in the cylinder, the insulation resistance in the spark plug discharge electrode is small, the system is set to gear 1, and the resistance connected in parallel at the high-voltage coil end of the ignition coil is set to a smaller value through a sliding rheostat. When the system determines that the current engine load is between 30% and 70%, the system is set to gear 2, and the resistance connected in parallel at the high-voltage coil end of the ignition coil is set to an intermediate value through a sliding rheostat. When the system determines that the current engine load is greater than 70%, at this time, due to the large amount of working fluid in the cylinder, the insulation resistance in the spark plug discharge electrode is large, the system is set to gear 3, and the resistance connected in parallel at the high-voltage coil end of the ignition coil is set to a larger value through a sliding rheostat.

[0060] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
