Description

Jointly controlled engine cylinder deactivation control method, device, electronic device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 6, 2023, with application number 202311145498.6, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the technical field of vehicle engine control evaluation, for example, to a method, device, electronic device and storage medium for controlling cylinder deactivation of a linked engine. Background Art

[0003] With the continuous development of engine technology, different types of engines have emerged, and even linked control engines have appeared. For example, the V-type engine has two banks of cylinders, and the two banks of cylinders are completely independent in mechanical structure, with their own complete intake, exhaust, fuel supply, and ignition subsystems. Each bank of cylinders is controlled by an electronic control unit (ECU), forming a dual-ECU linked control architecture.

[0004] A crucial aspect of dual-ECU engine control is determining the number and order of cylinder deactivations when torque reduction is required. Currently, each ECU calculates the number of cylinders to be deactivated separately, rounding the calculations to the nearest integer. However, this rounded sum often mismatches the actual number of cylinders to be deactivated. Furthermore, the fuel cut-off and injection sequence determined by each ECU differs from the actual one, easily leading to a mismatch in the deactivation order, potentially causing engine stall or even damage.

[0024] FIG1 is a flow chart of a method for controlling cylinder deactivation in a linked-control engine according to an embodiment of the present application. This embodiment is applicable to scenarios where cylinder deactivation in a linked-control engine is controlled. The method can be executed by any electronic control unit (ECU) in the linked-control engine. The device can be implemented in hardware and / or software and can generally be integrated into an electronic device such as a computer with data computing capabilities. The method includes the following steps:

[0025] Step 101: When a torque reduction request carrying a required torque is received, obtain the current torque and cylinder information of the cylinder corresponding to the second electronic control unit, and determine the cylinder corresponding to the second electronic control unit as a virtual cylinder of the first electronic control unit.

[0026] In this step, the second electronic control unit refers to the other electronic control unit in the joint control engine except the first electronic control unit. Most joint control engines are dual-joint control engines, that is, there are two electronic control units. Then the other electronic control unit except the first electronic control unit is the second electronic control unit in this step.

[0027] Of course, the method of this embodiment is described from the perspective of one electronic control unit in the joint-controlled engine, and the second electronic control unit also implements cylinder cut-off control according to the method of this embodiment.

[0028] It should be noted that the cylinder information may include the physical cylinder number and the working cylinder number of the cylinder, wherein the physical cylinder number refers to the sequence number defined based on the mechanical distribution of the cylinder, and the working cylinder number is the sequence number of the actual injection and ignition.

[0029] 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.

[0030] If the total number of cylinders in the joint control engine is N cyl Taking a dual-control engine as an example, in order to distinguish the two ECUs, they can be defined as the main ECU and the slave ECU respectively. Then the physical cylinder number of the cylinder responsible for the main ECU is The physical cylinder number of the cylinder that the slave ECU is responsible for is

[0031] It should be noted that the main and auxiliary ECUs communicate through a private control area network (CAN) to transmit cylinder information to each other.

[0032] If the first electronic control unit is the master ECU, then the cylinder in charge of the slave ECU is used as the virtual cylinder. Correspondingly, the physical cylinder numbers of all cylinders corresponding to the master ECU are in, The physical cylinder number of the virtual cylinder.

[0033] Taking a dual-control engine with each ECU responsible for four cylinders as an example, the physical cylinder numbers for the master ECU are 1, 2, 3, and 4, and the physical cylinder numbers for the slave ECU are 5, 6, 7, and 8. In this example, the injection and ignition sequence for multiple cylinders is shown in Figure 2, which is a schematic diagram of the working cylinder numbers for the dual-control engine provided in an embodiment of the present application.

[0034] As shown in Figure 2, Bank refers to the cylinders in the engine. The physical cylinder numbers of the cylinders are 1, 2, 3, 4, 5, 6, 7, and 8 from left to right and from 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.

[0035] Step 102 : Determine a cylinder deactivation sequence according to the cylinder information of the responsible cylinder of the first electronic control unit, the cylinder information of the virtual cylinder, the required torque, and the current torque.

[0036] In this step, the formula for calculating the number of cylinder cutoffs can be used first to determine the number of cylinder cutoffs based on the cylinder information of the responsible cylinder of the first electronic control unit, the cylinder information of the virtual cylinder, the required torque and the current torque; then the cylinder cutoff order can be determined based on the cylinder information of the responsible cylinder of the first electronic control unit, the cylinder information of the virtual cylinder, the preset cylinder cutoff distribution rules and the number of cylinder cutoffs.

[0037] Among them, when determining the number of cylinders to be cut off, the total number of cylinders of the responsible cylinders of the first electronic control unit and the virtual cylinders can be determined based on the cylinder information of the responsible cylinders of the first electronic control unit and the cylinder information of the virtual cylinders; then the formula for calculating the number of cylinders to be cut off can be used to determine the currently required number of cylinders to be cut off based on the total number of cylinders, the required torque and the current torque.

[0038] For example, since the cylinder information includes the physical cylinder number, the total number of cylinders can be determined by counting the number of physical cylinder numbers. In the above example, the physical cylinder number corresponding to the main ECU is Then there are N cyl Cylinders, the total number of cylinders is N cyl .

[0039] In addition, the formula for calculating the number of cylinder cutoffs is:

[0040] Among them, N cutnum is the number of cylinder cut-offs, x is the number of engine working cycles contained in a single control cycle, N cyl is the total number of cylinders, Tq needis the required torque, Tq act is the current torque.

[0041] Taking the above-mentioned dual-control eight-cylinder engine as an example, the total number of cylinders 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.

[0042] Substituting the above values ​​into the formula for calculating the number of cylinder cut-offs, we can get a value of 3.

[0043] It should be noted that the above x value can be customized according to needs. After experiments, x can be 2 in this embodiment.

[0044] In addition, when determining the cylinder cut-off sequence, the cylinder injection sequence can be determined first based on the cylinder information of the responsible cylinder of the first electronic control unit and the cylinder information of the virtual cylinder; then the cylinder cut-off sequence can be determined based on the preset cylinder cut-off distribution rules, the number of cylinders cut off and the cylinder injection sequence.

[0045] The cylinder information includes the working cylinder number of the cylinder, which is the cylinder injection order. Taking the above-mentioned dual-control eight-cylinder engine as an example, the working cylinder numbers of the cylinders (bank) responsible by the main ECU are 1, 3, 6, and 8, and the working cylinder numbers of the virtual cylinders of the main ECU are 2, 4, 5, and 7. The virtual cylinders are only used to participate in calculations, and the working cylinder numbers of the cylinder cut-off control period are 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8; the working cylinder numbers of the cylinders (bank) responsible by the slave ECU are 2, 4, 5, and 7. The working cylinder numbers of the virtual cylinders of the slave ECU are 1, 3, 6, and 8. The virtual cylinders are only used to participate in calculations, and the working cylinder numbers of the cylinder cut-off control period are 1, 2, 3, 4, 5, 6, 7, 8.

[0046] The cylinder cut-off control cycle is the cylinder injection sequence in the cycle, and the two are kept consistent, which can avoid cylinder cut-off control confusion.

[0047] In addition, it should be noted that when determining the cylinder injection sequence, the cylinder number of the current working cylinder can also be obtained by referring to the current working cylinder, and the cylinder number is used as the cycle starting cylinder number to determine the cylinder injection sequence.

[0048] If the working cylinder number of the current working cylinder is 3, then the working cylinder numbers of the aforementioned cylinder cut-off control cycle are 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8, 1, 2.

[0049] Furthermore, when determining the cylinder deactivation sequence, a pre-defined cylinder deactivation distribution rule is established to evenly distribute deactivated and normally operating cylinders to ensure consistent engine torque output. Furthermore, determining the specific cylinder numbers for deactivating injection can be referenced in related art and will not be further elaborated here.

[0050] Taking the aforementioned dual-control eight-cylinder engine as an example, the cylinder cut-off sequence determined by the main ECU is: cylinder number 1 does not spray fuel, cylinder number 2 sprays fuel, cylinder number 3 sprays fuel, cylinder number 4 sprays fuel, cylinder number 5 sprays fuel, cylinder number 6 does not spray fuel, cylinder number 7 sprays fuel, cylinder number 8 sprays fuel, cylinder number 1 sprays fuel, cylinder number 2 sprays fuel, cylinder number 3 sprays fuel, cylinder number 4 does not spray fuel, cylinder number 5 sprays fuel, cylinder number 6 sprays fuel, cylinder number 7 sprays fuel, and cylinder number 8 sprays fuel. Among them, the cylinders corresponding to cylinder number 2, cylinder number 4, cylinder number 5, and cylinder number 7 are virtual cylinders, and the oil cut-off and oil injection actions are not sent to the actuator.

[0051] After the same steps as above, the slave ECU determines the cylinder cut-off sequence as follows: cylinder number 1 does not spray oil, cylinder number 2 sprays oil, cylinder number 3 sprays oil, cylinder number 4 sprays oil, cylinder number 5 sprays oil, cylinder number 6 does not spray oil, cylinder number 7 sprays oil, cylinder number 8 sprays oil, cylinder number 1 sprays oil, cylinder number 2 sprays oil, cylinder number 3 sprays oil, cylinder number 4 does not spray oil, cylinder number 5 sprays oil, cylinder number 6 sprays oil, cylinder number 7 sprays oil, and cylinder number 8 sprays oil. Among them, the cylinders corresponding to cylinder number 1, cylinder number 3, cylinder number 6, and cylinder number 8 are virtual cylinders, and the oil cut-off and oil injection actions are not sent to the actuator.

[0052] Because the primary and secondary ECUs consider each other's bank's cylinder deactivation count when calculating the cylinder deactivation count, the cylinder deactivation count calculated by each ECU is the total cylinder deactivation count and is consistent with the correct cylinder deactivation count. This ensures that the cylinder deactivation count and deactivation sequence calculated by both ECUs are consistent and match the correct cylinder deactivation count and sequence, eliminating the need for adaptation and modification of the underlying control system for this function, significantly reducing its complexity.

[0053] Step 103 : Control the responsible cylinders of the first electronic control unit to cut off fuel or inject fuel based on the cylinder cut-off sequence, so as to implement cylinder cut-off control of the responsible cylinders of the first electronic control unit.

[0054] In this step, the responsible cylinders of the first electronic control unit only need to be controlled according to the aforementioned cylinder deactivation sequence, without the need to control the virtual cylinders.

[0055] In this embodiment, when a torque reduction request with a required torque is received, the current torque and the cylinder information of the cylinder corresponding to the second electronic control unit are obtained, and the cylinder corresponding to the second electronic control unit is determined as the virtual cylinder of the first electronic control unit; the cylinder deactivation order is determined based on the cylinder information of the responsible cylinder of the first electronic control unit, the cylinder information of the virtual cylinder, the required torque, and the current torque; based on the cylinder deactivation order, the responsible cylinder of the first electronic control unit is controlled to cut off oil or inject oil, so as to achieve cylinder deactivation control of the responsible cylinder of the first electronic control unit. Based on this, when determining the cylinder deactivation order, the present application will take into account the cylinder corresponding to the second electronic control unit and include it in the determination process as a virtual cylinder, thereby avoiding the situation where the number of deactivated cylinders that may be generated by separate calculations does not match the actual number.
