[0061] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0062] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than those illustrated or described herein.

[0063] Figure 1 A flow chart of a gas volume balance control method for a V-type engine provided by an embodiment of the present invention, wherein the electronic control units on both sides of the V-type engine include a first electronic control unit and a second electronic control unit, wherein the first electronic control unit and the second electronic control unit respectively control the intake volume of cylinders on both sides of the V-type engine, Figure 1 The gas volume balance control method of a V-type engine provided by an embodiment of the present invention includes:

[0064] S1. According to the driver's needs, the required torque is sent to the control units on both sides on average, and the electronic control units on both sides calculate the required intake volume based on the received torque.

[0065] The driver's demand can be obtained through the vehicle control unit (VCU). The VCU pre-stores the corresponding relationship between driving demand and required torque. For a V-type engine, the VCU sends the required torque to the first electronic control unit and the second control unit on average. For example, if the required torque is 2N, the required torque received by the first control unit and the second control unit is N. The electronic control unit pre-stores the corresponding relationship between torque and intake volume. The first electronic control unit and the second electronic control unit can calculate the required intake volume according to the received torque. For a V-type engine with a symmetrical structure, the required intake volume at both ends is equal.

[0066] S2. Obtain a target throttle opening according to the required air intake volume and the reverse calculation of the throttle model, and control the corresponding throttle opening.

[0067] Among them, the throttle model can be calibrated in advance according to the demand. The throttle model is the corresponding relationship between the throttle opening and the intake volume. When the required intake volume is known, the corresponding target throttle opening can be obtained by reverse calculation according to the throttle model. After determining the target throttle opening, the electronic control unit generates a control signal according to the target throttle opening to control the throttle action and realize throttle opening control.

[0068] S3. Obtain the operating status of the V-type engine.

[0069] Optionally, obtain the running status of the V-type engine, including:

[0070] Obtain the working status of the gas volume model sensor; the intake manifold pressure, speed and running time of the V-type engine.

[0071] S4. When the operating state meets the coordination condition, the difference between the intake amount calculated by the main charging model and the intake amount calculated by the throttle model is calculated according to the current actual intake state.

[0072] When the coordination conditions are met, it indicates that the V-type engine can control the gas volume balance. The main inflation model can be calibrated in advance and pre-stored in the storage unit of the V-type engine. Optionally, the operating state meets the coordination conditions, including: the gas volume model sensor works normally; the intake manifold pressure of the V-type engine is greater than or equal to a preset threshold, wherein the preset threshold can be 0.95 times the atmospheric pressure; the speed of the V-type engine is greater than the idle speed; the running time of the V-type engine is greater than or equal to the preset time, wherein the preset time can be designed according to actual needs, and the embodiment of the present invention does not limit this.

[0073] Optionally, the difference between the intake air volume calculated by the main charge model and the throttle model of the V-type engine is calculated according to the following formula:

[0074] (Intake manifold pressure - in-cylinder exhaust gas pressure) × conversion coefficient between pressure and intake volume;

[0075] Among them, the intake manifold pressure and the exhaust gas pressure in the cylinder are measured by sensors, and the conversion coefficient between pressure and intake volume is calibrated according to the V-type engine.

[0076] S5. Calculate the deviation of the gas flow rate according to the difference calculation of the throttle model, and correct the throttle model according to the deviation to obtain a corrected throttle model.

[0077] S6. Calculate a corrected target throttle opening according to the corrected throttle model.

[0078] S7. According to the corrected target throttle opening, the actual throttle opening is controlled to be equal to the required throttle opening, and S2 to S6 are executed in a loop until the actual intake amount calculated by the main charging model is equal to the intake amount calculated by the throttle model.

[0079] Through repeated adjustment and control through the above steps, the actual throttle opening will be controlled to be equal to the required throttle opening, and the actual intake volume calculated by the main charging model will be equal to the intake volume calculated by the throttle model. The required throttle opening is calculated using the reverse throttle model, so the actual intake volume will be equal to the required intake volume, and the required intake volumes on both sides are still equal, achieving equal control of the actual intake volumes on both sides.

[0080] On the basis of the above-mentioned embodiments, the existing V-type engine controlled by dual ECUs still has the following problems: the model deviation caused by sample differences may cause low intake volume on one side, resulting in unstable combustion and worsened emissions.

[0081] In order to solve the above problems, Figure 2 A flow chart of another gas volume balance control method for a V-type engine provided by an embodiment of the present invention. The gas volume balance control method is applicable to a situation where the V-type engine does not meet the coordination condition. Figure 2 , the gas volume balance control method comprises:

[0082] S1. According to the driver's needs, the required torque is sent to the electronic control units on both sides on average, and the electronic control units on both sides calculate the required intake volume according to the received torque.

[0083] S2. Obtain a target throttle opening according to the required air intake volume and the reverse calculation of the throttle model, and control the corresponding throttle opening.

[0084] S3. Obtain the operating status of the V-type engine.

[0085] S8. When the operating state does not meet the coordination condition, compare the actual intake volume with the minimum intake volume in the main charging model of the V-type engine.

[0086] When the operating state does not meet the coordination conditions, the state of the V-type engine is not sufficient to adjust the balance of the intake volume on both sides. In order to keep the V-type engine working, it is determined whether the actual intake volume is less than the minimum intake volume of the main charging model.

[0087] S9. If the actual air intake volume is less than the minimum air intake volume, the required air intake volume is corrected according to the difference between the actual air intake volume and the minimum air intake volume.

[0088] S10, obtaining a target throttle opening according to the corrected required air intake volume and the reverse calculation of the throttle model.

[0089] S11. Output a control signal to control the corresponding throttle opening according to the target throttle opening.

[0090] By comparing the difference between the actual intake volume and the minimum intake volume, the target throttle opening is corrected so that the actual intake volume is larger than the minimum intake volume, thus playing a protective role.

[0091] In another embodiment, the operating status of the V-type engine can be acquired in advance. Figure 3 A flow chart of another gas volume balance control method for a V-type engine provided by an embodiment of the present invention, wherein the same parts as those in the above-mentioned embodiment are not described in detail, and reference is made to FIG. Figure 3 , the gas volume balance control method includes:

[0092] S1. Obtain the operating status of the V-type engine.

[0093] S2. When the operating state meets the coordination conditions, the required torque is sent to the electronic control units on both sides on average according to the driver's needs, and the electronic control units on both sides calculate the required intake volume according to the received torque.

[0094] S3. Obtain a target throttle opening according to the required air intake volume and the reverse calculation of the throttle model, and control the corresponding throttle opening.

[0095] S4. Calculate the difference between the intake amount calculated by the main charging model and the intake amount calculated by the throttle model according to the current actual intake state.

[0096] S5. Calculate the deviation of the gas flow rate according to the difference calculation of the throttle model, and correct the throttle model according to the deviation to obtain a corrected throttle model.

[0097] S6. Calculate a corrected target throttle opening according to the corrected throttle model.

[0098] S7. According to the corrected target throttle opening, the actual throttle opening is controlled to be equal to the required throttle opening, and S2 to S6 are executed in a loop until the actual intake amount calculated by the main charging model is equal to the intake amount calculated by the throttle model.

[0099] Through repeated adjustment and control through the above steps, the actual throttle opening will be controlled to be equal to the required throttle opening, and the actual intake volume calculated by the main charging model is equal to the intake volume calculated by the throttle model. The required throttle opening is calculated using the reverse throttle model, so the actual intake volume will be equal to the required intake volume, and the required intake volumes on both sides are still equal, achieving equal control of the actual intake volumes on both sides.

[0101] S1. Obtain the operating status of the V-type engine.

[0102] S8. When the operating state does not meet the coordination condition, compare the actual intake volume with the minimum intake volume in the main charging model of the V-type engine.

[0103] S9. If the actual air intake volume is less than the minimum air intake volume, the required air intake volume is corrected according to the difference between the actual air intake volume and the minimum air intake volume.

[0104] S10, obtaining a target throttle opening according to the corrected required air intake volume and the reverse calculation of the throttle model.

[0105] S11. Output a control signal to control the corresponding throttle opening according to the target throttle opening.
