Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of vehicle engine control evaluation, and particularly relate to a method and device for cylinder cut-off control of a jointly controlled engine, an electronic device, and a storage medium. BACKGROUND

[0002] With the continuous development of engine technology, different types of engines have emerged, and even jointly controlled engines have appeared, such as V-type engines, which have two rows of cylinders and are completely independent in mechanical structure, with complete intake, exhaust, oil supply, and ignition subsystems. Each row of cylinders is controlled by an electronic control unit (ECU), forming a dual-ECU joint control architecture.

[0003] In the control process of a dual-ECU jointly controlled engine, it is important to determine the number and sequence of cylinders to be cut off when the torque needs to be reduced. Currently, when determining the number of cylinders to be cut off, two ECUs calculate separately, and the calculation is rounded. However, the sum of the rounded number of cylinders to be cut off and the actual required number of cylinders to be cut off usually does not match, and the determined fuel cut-off and injection sequence of each ECU also does not match the actual situation, which easily causes disorder in the sequence of cylinder cut-off, resulting in engine stall or even damage. SUMMARY

[0004] Embodiments of the present application provide a method and device for cylinder cut-off control of a jointly controlled engine, an electronic device, and a storage medium to avoid the situation where the sum of the rounded number of cylinders to be cut off and the actual required number of cylinders to be cut off do not match.

[0009] In a second aspect, embodiments of the present application also provide a device for cylinder cut-off control of a jointly controlled engine, applied to any electronic control unit of the jointly controlled engine, and the method comprises:

[0012] The cylinder cut-off control module is used to control the cylinders under the responsibility of this electronic control unit to cut off or inject fuel based on the cylinder cut-off sequence, so as to realize the cylinder cut-off control of the cylinders under the responsibility of this electronic control unit.

[0013] Thirdly, embodiments of this application also provide an electronic device, including:

[0014] One or more processors;

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0024] Example 1

[0025] Figure 1 This is a flowchart illustrating the cylinder deactivation control method for a coupled engine provided in Embodiment 1 of this application. This embodiment is applicable to scenarios involving cylinder deactivation control in coupled engines. This method can be executed by any electronic control unit (ECU) in the coupled engine. The device can be implemented in hardware and / or software and is generally integrated into electronic devices such as computers with data processing capabilities. Specifically, it includes the following steps:

[0026] Step 101: Upon receiving a request to reduce torque, obtain the current torque, cylinder information of the corresponding cylinders of other electronic control units, and identify the corresponding cylinders of other electronic control units as virtual cylinders of this electronic control unit.

[0027] In this step, "other electronic control units" refers to other electronic control units in the engine besides this one. In a specific example, most engines are dual-control engines, meaning there are two electronic control units. In this case, the other electronic control unit besides this one is the "other electronic control unit" in this step.

[0028] Of course, the method in this embodiment is described from the perspective of one electronic control unit in the joint control engine. Other electronic control units also implement cylinder deactivation control according to the method in this embodiment.

[0029] It should be noted that cylinder information can include the physical cylinder number and the working cylinder number. The physical cylinder number refers to the sequence number defined from the mechanical distribution of the cylinder, while the working cylinder number is the actual injection and ignition sequence number.

[0030] In addition, the working cylinder number is usually related to the mechanical structure of the engine and is usually predefined. Therefore, this step can directly obtain the working cylinder number from the corresponding storage location.

[0031] If the total number of cylinders in the joint control engine is N cyl Taking a dual-control engine as an example, to distinguish between the two ECUs, they can be defined as the main ECU and the auxiliary ECU. The physical cylinder number of the cylinder controlled by the main ECU is... The physical cylinder number that the secondary ECU is responsible for is:

[0032] It should be noted that the main and auxiliary ECUs communicate with each other via a proprietary CAN bus to exchange cylinder information.

[0033] If this electronic control unit is the main ECU, then the cylinders controlled by the secondary ECU will be treated as virtual cylinders, and the corresponding physical cylinder numbers will be... in, N cyl This is the physical cylinder number of the virtual cylinder.

[0034] In a specific example, taking a dual-control engine where each ECU is responsible for four cylinders, the main ECU is responsible for cylinders 1, 2, 3, and 4, while the secondary ECU is responsible for cylinders 5, 6, 7, and 8. In this example, the number of fuel injection ignitions for each cylinder is as follows: Figure 2 As shown, Figure 2 A schematic diagram of the working cylinder numbers of a dual-control engine cylinder provided for Embodiment 1 of this application.

[0035] like Figure 2 As shown, "Bank" refers to the cylinder in the engine. The physical cylinder numbers are 1, 2, 3, 4, 5, 6, 7, and 8 from left to right and top to bottom. Working cylinder number 1 corresponds to physical cylinder number 1, working cylinder number 2 corresponds to physical cylinder number 5, working cylinder number 3 corresponds to physical cylinder number 4, working cylinder number 4 corresponds to physical cylinder number 8, working cylinder number 5 corresponds to physical cylinder number 6, working cylinder number 6 corresponds to physical cylinder number 3, working cylinder number 7 corresponds to physical cylinder number 7, and working cylinder number 8 corresponds to physical cylinder number 2.

[0036] Step 102: Determine the cylinder cut-off sequence based on the cylinder information of the cylinder under the control of this electronic control unit, the cylinder information of the virtual cylinder, the required torque, and the current torque.

[0037] In this step, the cylinder failure number can be determined first using the cylinder failure calculation formula based on the cylinder information of the cylinders under the control of this electronic control unit, the cylinder information of the virtual cylinders, the required torque, and the current torque. Then, the cylinder failure sequence can be determined based on the cylinder information of the cylinders under the control of this electronic control unit, the cylinder information of the virtual cylinders, the preset cylinder failure distribution rules, and the total number of cylinder failures.

[0038] When determining the number of cylinders to be cut off, the total number of cylinders and virtual cylinders under the control of this electronic control unit can be determined first based on the cylinder information of the cylinders under the control of this electronic control unit and the cylinder information of the virtual cylinders. Then, the number of cylinders to be cut off is determined by using the cylinder cut-off number calculation formula based on the total number, the required torque, and the current torque.

[0039] For example, since the cylinder information includes physical cylinder numbers, the total number of cylinders can be determined by counting the number of physical cylinder numbers. In the example above, the physical cylinder number corresponding to the main ECU is... So there are a total of N. cyl There are 1 cylinder, and the total number is N. cyl .

[0040] In addition, the formula for calculating the number of cylinder failures is:

[0041] Where, N cutnum N represents the total number of cylinders that have failed to turn off, x represents the number of engine duty cycles contained in a single control cycle, and N represents the total number of cylinders that have failed to turn off. cyl Tq represents the total quantity. need For the required torque, Tq act This represents the current torque.

[0042] Taking the aforementioned dual-control eight-cylinder engine as an example, the total number is 8, the number of working cycles is 2, the required torque is 13a, and the current torque is 16a, where 13a and 16a are exemplary values.

[0043] Substituting the above values ​​into the formula for calculating the number of cylinder failures, we get the number of cylinder failures as 3.

[0044] It should be noted that the above x value can be customized according to requirements. Based on experiments, 2 is the optimal value in this embodiment.

[0045] In addition, when determining the cylinder cut-off sequence, the cylinder injection sequence can be determined first based on the cylinder information of the cylinders under the control of this electronic control unit and the cylinder information of the virtual cylinders; then, the cylinder cut-off sequence can be determined based on the preset cylinder cut-off distribution rules, the number of cylinder cut-offs, and the cylinder injection sequence.

[0046] Specifically, the cylinder information includes the working cylinder number, which is the cylinder injection sequence. Taking the aforementioned dual-control eight-cylinder engine as an example, the working cylinder numbers for the main ECU are 1, 2, 3, 4, 5, 6, 7, and 8, where 2, 4, 5, and 7 are virtual cylinder numbers used only for calculation. The cylinder cutoff control cycle is 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8. The working cylinder numbers for the secondary ECU are 1, 2, 3, 4, 5, 6, 7, 8, where 1, 3, 6, and 8 are virtual cylinder numbers used only for calculation. The cylinder cutoff control cycle is 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8.

[0047] The cylinder cutoff control cycle is the cylinder injection sequence within that cycle. Maintaining consistency between the two can prevent cylinder cutoff control from going awry.

[0048] Additionally, it should be noted that when determining the cylinder injection sequence, the current working cylinder can also be referenced. Specifically, the working cylinder number of the current working cylinder is obtained and used as the starting working cylinder number of the cycle to determine the cylinder injection sequence.

[0049] In a specific example, if the working cylinder number of the current working cylinder is 3, then the aforementioned cylinder cut-off control cycle is 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8, 1, 2.

[0050] Furthermore, when determining the cylinder cut-off sequence, the principle of the preset cylinder cut-off distribution rule is to evenly distribute the cylinders with cut-off fuel injection and the normally operating cylinders to ensure the continuity of engine torque output. Additionally, determining the operating cylinder number of the specific cylinders that need to have their fuel injection cut off can be found in relevant technologies, which will not be elaborated upon here.

[0051] Taking the aforementioned dual-control eight-cylinder engine as an example, the cylinder cut-off sequence determined by the main ECU is: 1 no fuel injection, 2 fuel injection, 3 fuel injection, 4 fuel injection, 5 fuel injection, 6 no fuel injection, 7 fuel injection, 8 fuel injection, 1 fuel injection, 2 fuel injection, 3 fuel injection, 4 no fuel injection, 5 fuel injection, 6 fuel injection, 7 fuel injection, 8 fuel injection. Among them, cylinders 2, 4, 5, and 7 are virtual cylinders, and the fuel cut-off and fuel injection actions are not sent to the actuator.

[0052] After the same steps are performed, the auxiliary ECU determines the cylinder cut-off sequence as follows: 1 no fuel injection, 2 fuel injection, 3 fuel injection, 4 fuel injection, 5 fuel injection, 6 no fuel injection, 7 fuel injection, 8 fuel injection, 1 fuel injection, 2 fuel injection, 3 fuel injection, 4 no fuel injection, 5 fuel injection, 6 fuel injection, 7 fuel injection, 8 fuel injection. Among them, cylinders 1, 3, 6, and 8 are virtual cylinders, and the fuel cut-off and fuel injection actions are not sent to the actuator.

[0053] Because the primary and secondary ECUs consider the cylinder deactivation counts from each other's banks when calculating the cylinder deactivation count, their respective calculated cylinder deactivation counts are the total cylinder deactivation counts, and these counts are consistent with the correct cylinder deactivation counts. Therefore, it can be guaranteed that the cylinder deactivation counts and cylinder deactivation sequences calculated by the two ECUs are consistent and match the correct cylinder deactivation counts and sequences. No adaptation or modification to the underlying control system is required for this function, significantly reducing the complexity of the underlying control system.

[0054] Step 103: Based on the cylinder cut-off sequence control, the cylinders under the control of this electronic control unit are cut off from fuel or injected with fuel to achieve cylinder cut-off control of the cylinders under the control of this electronic control unit.

[0055] In this step, following the aforementioned cylinder cut-off sequence, only the cylinders controlled by this electronic control unit need to be controlled; there is no need to control the virtual cylinders.

[0056] In this embodiment, upon receiving a request to reduce torque due to a required torque, the system acquires the current torque, cylinder information of cylinders corresponding to other electronic control units (ECUs), and designates cylinders corresponding to other ECUs as virtual cylinders of this ECU. The cylinder cut-off sequence is determined based on the cylinder information of the cylinders controlled by this ECU, the cylinder information of the virtual cylinders, the required torque, and the current torque. Based on the cylinder cut-off sequence, the system controls the cylinders controlled by this ECU to either cut off or inject fuel, thereby achieving cylinder cut-off control of the cylinders controlled by this ECU. Therefore, when determining the cylinder cut-off sequence, this application considers cylinders corresponding to other ECUs and includes them as virtual cylinders in the determination process, thus avoiding discrepancies between the actual number of cylinders cut off and the number calculated separately.
