[0043] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0044] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0045] The main solution of the embodiment of the present application is: running the ignition and fuel injection algorithm through the first core in the multi-core single-chip microcomputer of the engine system; and controlling the ignition and fuel injection of the engine through the ignition and fuel injection algorithm and the engine operating conditions.

[0046] Since the current MCU fuel injection and ignition are based on a single-core MCU, the OS system tasks, ignition and fuel injection pulse output, and ignition and fuel injection time calculation are all run serially in one core, which can easily lead to task suppression, resulting in abnormal fuel injection and ignition and system failure.

[0047] The present application provides a solution, which runs the ignition fuel injection algorithm through the first core in the multi-core single-chip microcomputer of the engine system; and controls the ignition fuel injection of the engine through the ignition fuel injection algorithm and the engine operating conditions. Since the present application improves the single-core single-chip microcomputer in the engine system into a multi-core single-chip microcomputer, and then runs the ignition fuel injection algorithm through a core in the multi-core single-chip microcomputer, and the first core is responsible for controlling the ignition fuel injection of the engine according to the ignition fuel injection algorithm and the engine operating conditions, the real-time performance of the engine can be greatly improved through multi-core parallelism, avoiding the problem of task suppression, which leads to abnormal fuel injection ignition, improving the engine control accuracy, and improving the engine's operating performance.

[0048] It should be noted that the execution subject of the method of this embodiment can be an automobile engine control system with engine ignition and fuel injection control, network communication and program running functions; it can also be a car equipped with an automobile engine control system. This embodiment and the following embodiments will be described by taking the automobile engine control system as an example.

[0049] Based on this, the embodiment of the present application provides an engine ignition injection control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the engine ignition and fuel injection control method of the present application.

[0050] In this embodiment, the engine ignition fuel injection control method includes steps S10 to S20:

[0051] Step S10: running an ignition and fuel injection algorithm through a first core in a multi-core single-chip microcomputer of the engine system.

[0052] It can be understood that this embodiment uses a multi-core single-chip microcomputer in the engine system, and the core engine synchronization cylinder judgment and ignition injection pulse generation, engine ignition time injection time calculation and general engine tasks are run in parallel on three independent cores of the single-chip microcomputer, which greatly improves the real-time performance, improves the engine control accuracy, improves the engine operation performance, reduces fuel consumption, and improves fuel economy. Among them, the first core Core1 in the multi-core single-chip microcomputer runs the engine injection ignition algorithm.

[0053] Step S20, controlling the ignition and fuel injection of the engine by means of the ignition and fuel injection algorithm and the engine operating conditions.

[0054] It should be understood that the first core Core1 calculates the parameters related to ignition injection through the engine injection ignition algorithm, and controls the engine ignition injection through the calculated parameters combined with the engine operating conditions (such as load, speed, water temperature, etc.).

[0055] In a feasible implementation manner, before step S10, steps S01 to S03 may also be included:

[0056] Step S01, running an operating system task through the third core in the multi-core microcontroller.

[0057] It should be understood that in order to further reduce the load of the first core Core1, in this embodiment, the operating system task is run separately in the third core Core3 in the multi-core microcontroller.

[0058] Step S02, selecting a communication protocol through the operating system task, and establishing an inter-core communication channel between multiple cores in a multi-core microcontroller of an engine system according to the communication protocol.

[0059] It is understandable that the operating system task performs communication protocol related operations in the third core Core3. First, select the communication protocol. In the fuel injection ignition system based on a single-core microcontroller, it is very important to select a suitable communication protocol. Common communication protocols include CAN bus, LIN bus, SPI, I2C, etc. These protocols have their own advantages and disadvantages and are suitable for different application scenarios. For example, CAN bus is widely used in the field of automotive electronics due to its high reliability, real-time performance and flexibility.

[0060] It should be understood that after selecting the corresponding communication protocol, the specific functions of the communication protocol need to be implemented in the OS system task, including data transmission and reception, error detection and processing, etc. This usually involves the writing of interrupt service programs to ensure timely response and processing when data is received. According to the communication protocol, an inter-core communication channel between multiple cores in the multi-core microcontroller of the engine system is established to facilitate multi-core communication.

[0061] Step S03, executing the power-on and power-off logic of the engine system through the operating system task.

[0062] It is understandable that the operating system task can also execute the power-on and power-off logic in the third core Core3. When the system is powered on, a series of self-test operations need to be performed to ensure that each module is working properly. This includes checking the power supply voltage, clock signal, memory status, etc. After the power-on self-test passes, the system will enter the initialization configuration phase. In this phase, the operating mode, clock frequency, IO port status, etc. of the microcontroller need to be set. In order to protect system safety and extend the life of the equipment, it is necessary to implement reasonable power-on and power-off control logic. For example, when shutting down the system, it is necessary to shut down each module in a certain order to prevent data loss or equipment damage.

[0063] In this implementation, by running the OS system task separately in a core Core1, it avoids occupying the resources of the core Core1 that runs the engine injection and ignition algorithm, thereby further ensuring the stable execution of the ignition injection algorithm, avoiding task suppression, and improving the parallel operation efficiency and accuracy of the single-chip microcomputer.

[0064] This embodiment provides an engine ignition fuel injection control method, which runs an ignition fuel injection algorithm through the first core in the multi-core single-chip microcomputer of the engine system; and controls the ignition fuel injection of the engine through the ignition fuel injection algorithm and the engine operating conditions. Since this embodiment improves the single-core single-chip microcomputer in the engine system into a multi-core single-chip microcomputer, and then runs the ignition fuel injection algorithm through a core in the multi-core single-chip microcomputer, and the first core is responsible for controlling the ignition fuel injection of the engine according to the ignition fuel injection algorithm and the engine operating conditions, the real-time performance of the engine can be greatly improved through multi-core parallelism, avoiding task suppression, resulting in abnormal fuel injection ignition problems, improving the engine control accuracy, and improving the engine's operating performance.

[0065] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , step S20, the engine ignition injection control method further includes steps S201 to S203:

[0066] Step S201, determining ignition injection parameters through the ignition injection algorithm and the engine operating conditions, wherein the ignition injection parameters include ignition time, injection time, injection advance angle and injection pulse width.

[0067] It should be understood that the first core Core1 calculates ignition injection parameters, including ignition timing, injection timing, injection advance angle, injection pulse width and other parameters, through an ignition injection algorithm and engine operating conditions.

[0068] Step S202: transmitting the ignition injection parameters to the second core in the multi-core microcontroller through an inter-core communication channel.

[0069] It is understandable that in this embodiment, the timer for controlling the ignition and fuel injection is also independently run in the second core Core2 of the multi-core microcontroller. The structure of the multi-core microcontroller can be referred to Figure 3, the first core Core1, the second core Core2, the third core Core3. The first core Core1 runs the algorithm for engine injection and ignition, and calculates parameters such as ignition time, injection time, injection advance angle and injection pulse width. The injection advance angle refers to the crankshaft angle of the piston from the top dead center when the injector starts to inject fuel. The injection pulse width refers to the duration of the injector injection, usually in milliseconds (ms). The second core Core2 runs the timer for controlling ignition and injection, multiplies the frequency to generate tooth signals, and generates ignition pulses and injection pulses. The third core Core3 runs OS system tasks, communication protocols, and power-on and power-off logic.

[0070] It can be understood that the first core Core1 transmits the ignition injection parameters to the second core Core2 in the multi-core microcontroller through the inter-core communication channel.

[0071] Step S203: Controlling the ignition and fuel injection of the engine according to the ignition and fuel injection parameters through the second core.

[0072] It should be understood that the second core Core2 runs a timer for controlling ignition and fuel injection, and the timer generates a tooth signal according to the ignition and fuel injection parameter multiplication, generates an ignition pulse and a fuel injection pulse, and controls the ignition and fuel injection of the engine.

[0073] In a feasible implementation, step S203 may include steps S31 to S34:

[0074] Step S31, initializing the ignition injection timer through the second core.

[0075] It can be understood that the second core Core2 initializes the ignition injection timer.

[0076] Step S32: determining the tooth signal of the engine through the second core.

[0077] It is understandable that when the engine is started, the second core needs to achieve fast synchronization with the EPM (engine position module) to release the injection and ignition signals and finally achieve the purpose of successful starting. Therefore, it is necessary to determine the engine tooth signal through the timer in the second core.

[0078] In a feasible implementation manner, step S32 may include steps S321 to S322:

[0079] Step S321: determining a missing tooth signal and phase information according to a crankshaft signal and a camshaft signal through the second kernel.

[0080] It is understandable that the second core can detect specific features in the crankshaft and camshaft signals, such as missing tooth signals, to determine the working state of each cylinder (i.e., the state of each cylinder in intake, compression, power and exhaust). The second core can also determine whether the phase information of the engine (i.e., the relative position of the crankshaft and the camshaft) is correct based on the two signals of the crankshaft and the camshaft.

[0081] Step S322, generating an engine tooth signal by multiplying the missing tooth signal and the phase information through the ignition injection timer.

[0082] It can be understood that the fuel injection timer can generate a tooth signal by multiplying the frequency according to the missing tooth signal and the phase information.

[0083] Step S33, determining an ignition pulse signal and an injection pulse signal according to the ignition injection parameter and the tooth signal.

[0084] It is understandable that the injection pulse signal can be calculated according to the injection time and tooth signal in the ignition injection parameters, and the ignition pulse signal can be calculated according to the parameters such as ignition time, injection advance angle and injection pulse width in the ignition injection parameters. The overall process of the engine ignition injection control method in this embodiment can be referred to Figure 4 .

[0085] Step S34, controlling the ignition and fuel injection of the engine according to the ignition pulse signal and the fuel injection pulse signal through the ignition and fuel injection timer.

[0086] In a feasible implementation manner, step S34 may include steps S341 to S342:

[0087] Step S341, driving the ignition coil according to the ignition pulse signal through the ignition injection timer.

[0088] Step S342, driving the fuel injector according to the fuel injection pulse signal to control the ignition and fuel injection of the engine.

[0089] It can be understood that Core1 and Core2 communicate with each other, and the ignition time, injection pulse width and other parameters of Core1 are passed to Core2. The timer on Core2 generates an ignition pulse to drive the ignition coil, and the injection signal drives the injector, thereby achieving precise control of the engine's ignition and injection.

[0090] In this embodiment, the first core calculates the optimal injection time and ignition time and advance angle according to different working conditions of the engine. The tooth signal of the engine is determined according to the crankshaft signal and the camshaft signal. The timer on Core2 determines the missing tooth signal and phase information according to the crankshaft and camshaft signals, generates the tooth signal by frequency multiplication, and synchronizes the cylinder of the engine. Core1 and Core2 communicate with each other, and the ignition time, injection pulse width and other parameters of Core1 are passed to Core2. The timer on Core2 generates an ignition pulse to drive the ignition coil, and the injection signal drives the injector, thereby realizing precise control of the ignition and injection of the engine. By running multiple cores in parallel, task suppression is avoided, the control accuracy of ignition and injection is improved, fuel consumption is reduced, fuel economy is improved, real-time performance is greatly improved, engine control accuracy is improved, and engine operating performance is improved.

[0091] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the engine ignition injection control method of the present application.
