[0032] 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.
[0033] During the engine compression process, 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 also continue to heat up, eventually igniting 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 detonation, power loss, engine overheating, and in severe cases, engine damage. Studies have shown that ignition energy can significantly affect the combustion rate of hydrogen. Because the minimum ignition energy of hydrogen is 1 / 10 of that of gasoline, the energy stored in the ignition coil cannot be fully consumed during the spark plug breakdown discharge stage. Excess energy will be stored in the ignition coil, which can easily 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, Figure 1 As shown, a vehicle driving control method is provided. This embodiment uses the method applied to a terminal as an example for illustration. It is understandable that the method can also be applied to a server, or to a system including a terminal and a server, and implemented through 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. Therefore, 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 through 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 controls parameters such as ignition timing, ignition energy and ignition mode according to the engine's operating state and external conditions to achieve effective combustion of hydrogen in the engine cylinder; the resistance value adjustment method of the variable resistor can be, but is not limited to, adjustment through a sliding rheostat, thermal adjustment or pressure-sensitive adjustment.
[0039] S106: Control vehicle driving based on the ignition strategy.
[0040] Among them, based on the ignition strategy, sufficient sparks are generated by the spark plug at the right time to ignite the mixed gas, thereby driving the hydrogen engine to work.
[0041] In the aforementioned vehicle driving control method, for a vehicle equipped with a hydrogen engine, the engine load is acquired in real time during driving. A variable resistor is connected in parallel to the high-voltage coil in the hydrogen engine's ignition coil. Based on the engine load, the resistance value of the variable resistor is adjusted to adjust the hydrogen engine's ignition strategy. Vehicle driving is then controlled based on the ignition strategy. The method provided in this application can effectively prevent pre-ignition and backfire problems in hydrogen engines.
[0042] In some embodiments, as Figure 2 As shown, the vehicle's engine load is obtained in real time, including:
[0043] S202: Acquire the vehicle's engine speed, throttle opening, and engine torque 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 a target load range; obtaining a 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, namely 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, the resistance value is positively correlated with 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, making the driving process of the vehicle cleaner and more energy-efficient.
[0057] In one embodiment, Figure 3 As shown, another vehicle driving control method is provided, which includes the following contents:
[0058] This embodiment provides a method for dissipating excess ignition energy by connecting a dissipative resistor in parallel with the ignition coil, thereby suppressing pre-ignition or backfire caused by abnormal discharge in the ignition coil. Because the working fluid in the cylinder varies under different engine loads, the insulation resistance in the spark plug discharge electrode varies. Therefore, different resistors are required in parallel with the high-voltage coil of the ignition coil under different operating conditions. If the parallel resistor value is too low, all the ignition energy will leak out of the parallel resistor, preventing the working fluid in the combustion chamber from igniting properly. If the parallel resistor value is too high, the residual energy in the ignition coil cannot be dissipated through the parallel resistor, which can still lead to pre-ignition or backfire.
[0059] During vehicle operation, the system determines the current engine load by reading information such as engine speed, throttle opening, and torque transmitted by the ECU. When the system determines that the current engine load is less than 30%, the insulation resistance in the spark plug discharge electrode is low due to the low working fluid in the cylinder. The system is set to gear 1, and the resistance connected in parallel with the high-voltage coil end of the ignition coil is set to a low value via 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 with the high-voltage coil end of the ignition coil is set to an intermediate value via a sliding rheostat. When the system determines that the current engine load is greater than 70%, the insulation resistance in the spark plug discharge electrode is high due to the high working fluid in the cylinder. The system is set to gear 3, and the resistance connected in parallel with the high-voltage coil end of the ignition coil is set to a high value via a sliding rheostat.
