Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an engine intake control method, device, vehicle, storage medium and product. Background Art

[0002] At present, vehicle intake volume control is mainly carried out by intake manifold pressure (P system) or intake flow, namely HFM (Hot Film Air Meter) system, which has high control accuracy under steady-state conditions.

[0003] In the related technology, the main working principle of the mass flow meter system is to measure the mass flow of air entering the engine, and determine the intake volume of the engine by measuring the mass of air entering the engine. This flow meter has high durability, stability and accuracy, can adapt to high-pressure and high-flow working conditions, and does not require additional pressure and temperature compensation; the main working principle of the intake manifold pressure system is to calculate the intake volume by measuring the pressure changes inside the engine or the intake system. This method mainly relies on the accuracy and response speed of the pressure sensor. In high-flow or high-pressure environments, its accuracy and stability are not as good as the mass flow meter system. In addition, compared with the HFM system, the pressure system requires additional calibration and compensation of the pressure to adapt to different working conditions.

[0004] In the relevant technology, the vehicle control adopts either the P system or the HFM system; the former has better control transient response but poor control accuracy; the latter has higher steady-state control accuracy but poor transient control response. When the engine is in transient conditions, the actual intake volume fluctuates greatly due to the influence of throttling, eddy current, turbulence, etc. on the intake pipe and throttle, which will interfere with the reading accuracy of the pressure sensor and flow meter, resulting in the inability to accurately control the intake volume. Poor transient control of the whole vehicle not only affects the vehicle driving experience, but may also cause serious damage to the vehicle. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The following describes the engine intake control method, device, vehicle, storage medium and product of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that when the engine is in a transient working condition, the throttling, vortex and turbulence phenomena in the intake pipe and the throttle valve will cause large fluctuations in the actual intake volume, thereby affecting the measurement accuracy of the pressure sensor and the flow meter, resulting in inaccurate intake volume control, the present application provides an engine intake control method, in which the target intake volume of the engine at the current moment is calculated by the driver's required torque at the current moment, the target intake volume is input into at least one of the intake manifold pressure system and the mass flow meter system, and the intake volume of the engine is controlled based on at least one of the intake manifold pressure system and the mass flow meter system, and the control is carried out by dual systems and dual modes to ensure the accuracy of intake volume calculation. Thus, the problem that when the engine is in a transient working condition, the throttling, vortex and turbulence phenomena in the intake pipe and the throttle valve will cause large fluctuations in the actual intake volume, thereby affecting the measurement accuracy of the pressure sensor and the flow meter, resulting in inaccurate intake volume control is solved.

[0028] Specifically, Figure 1 A flow chart of an engine air intake control method provided in an embodiment of the present application.

[0029] like Figure 1 As shown, the engine intake air quantity control method comprises the following steps:

[0030] In step S101 , the current driver's required torque is obtained.

[0031] Among them, torque refers to the rotational torque generated by the engine or electric motor on the crankshaft or drive shaft, and is an important indicator to measure the output power of the engine or motor; the driver's required torque can be obtained by detecting the degree to which the driver presses the accelerator pedal.

[0032] It is understandable that the embodiment of the present application can obtain the driver's required torque by detecting the degree to which the driver presses the accelerator pedal, etc.

[0033] In step S102, the target intake air amount of the engine at the current moment is calculated according to the torque required by the driver at the current moment.

[0034] The target intake air volume may be calculated by an EMS (Engine Management System) based on an engine characteristic curve, wherein the engine characteristic curve includes a relationship between the intake air volume and the torque under different operating conditions.

[0035] It is understandable that the embodiment of the present application can calculate the target intake volume of the engine at the current moment according to the required torque of the driver at the current moment through the EMS based on the engine characteristic curve.

[0036] In step S103, the target intake air amount is input into at least one of an intake manifold pressure system and a mass flow meter system, and the intake air amount of the engine is controlled based on at least one of the intake manifold pressure system and the mass flow meter system.

[0037] Among them, the intake manifold pressure system refers to a system used to measure the internal pressure of the engine intake manifold, referred to as the P system. Its main working principle is to calculate the intake volume by measuring the pressure changes inside the engine or the intake system. It mainly relies on the accuracy and response speed of the pressure sensor. Under high flow or high pressure environment, its accuracy and stability are not as good as the mass flow meter system, and the pressure needs additional calibration and compensation to adapt to different working conditions; the mass flow meter system, the main working principle is to measure the mass flow rate of air entering the engine, and determine the engine's intake volume by measuring the mass of air entering the engine. This flowmeter has high durability, stability and accuracy, can adapt to high-pressure and large-flow working conditions, and does not require additional pressure and temperature compensation.

[0038] It can be understood that the embodiment of the present application can input the calculated target intake volume of the engine at the current moment into at least one of the intake manifold pressure system and the mass flow meter system according to some judgment methods. The method of judging whether to input the intake manifold pressure system, the mass flow meter system or both will be described in detail below and will not be repeated here. After inputting at least one of the intake manifold pressure system and the mass flow meter system, the intake volume of the engine is controlled based on at least one of the intake manifold pressure system and the mass flow meter system.

[0039] In an embodiment of the present application, the intake volume of the engine is controlled based on at least one of the intake manifold pressure system and the mass flow meter system, including: identifying the current driving mode of the vehicle; if the current driving mode is the first driving mode, determining at least one of the intake manifold pressure system and the mass flow meter system to control the intake volume of the engine based on the current operating conditions; if the current driving mode is the second driving mode, controlling the intake volume of the engine based on the intake manifold pressure system and the mass flow meter system.

[0040] Among them, the first driving mode is the conventional control mode; the second driving mode is the aggressive control mode.

[0041] It can be understood that the embodiment of the present application can identify whether the vehicle is in the first driving mode, that is, the conventional control mode, or the second driving mode, that is, the aggressive control mode. When it is identified that the vehicle is in the first driving mode, at least one of the intake manifold pressure system and the mass flow meter system is determined to control the intake volume of the engine based on the current operating conditions. This process will be described in detail below and will not be repeated here. When it is identified that the vehicle is in the second driving mode, the intake volume of the engine is controlled jointly based on the intake manifold pressure system and the mass flow meter system.

[0042] In an embodiment of the present application, at least one of the intake manifold pressure system and the mass flow meter system is determined based on the current operating condition to control the intake amount of the engine, including: if the current operating condition is a first condition, the intake amount of the engine is controlled based on the mass flow meter system; if the current operating condition is a second condition, the intake amount of the engine is determined based on the actual load of the vehicle.

[0043] Among them, the first operating condition is the steady-state operating condition; the second operating condition is the non-steady-state operating condition; whether the vehicle is in a steady-state operating condition can be judged by indicators such as the vehicle's speed and acceleration, engine speed and accelerator pedal position; the actual load refers to the effective load borne by the vehicle during operation, reflecting the resistance that the vehicle needs to overcome and the ability to complete the work under the current operating conditions.

[0044] It can be understood that in the embodiment of the present application, when it is identified that the vehicle is in the first driving mode, it is determined whether the vehicle is in the first operating condition. If the vehicle is in the first operating condition, the mass flow meter system is used to control the intake volume of the engine; if the vehicle is in the second operating condition, at least one of the intake manifold pressure system and the mass flow meter system is determined to control the intake volume of the engine according to the actual load of the vehicle. The details will be described below and will not be repeated here.

[0045] In an embodiment of the present application, at least one of an intake manifold pressure system and a mass flow meter system is determined according to the actual load of the vehicle to control the intake amount of the engine, including: calculating a load correction factor according to the actual load, correcting the required torque according to the load correction factor, and correcting the target intake amount based on the corrected required torque; if the load correction factor is less than or equal to a first set threshold, the corrected target intake amount is input into the mass flow meter system, and the intake amount of the engine is controlled based on the mass flow meter system; if the load correction factor is greater than the first set threshold and less than or equal to a second set threshold, the corrected target intake amount is input into the intake manifold pressure system, and the intake amount of the engine is controlled based on the intake manifold pressure system, wherein the second set threshold is greater than the first set threshold; if the load correction factor is greater than the second set threshold, the corrected target intake amount is input into the intake manifold pressure system and the mass flow meter system, and the intake amount of the engine is controlled based on the mass flow meter system and the mass flow meter system.

[0046] Among them, the first set threshold and the second set threshold are load correction factor values ​​set according to actual requirements, which are set according to actual needs and are not specifically limited here; the determination of the load correction factor will be described in detail below and will not be repeated here.

[0047] It can be understood that, in the embodiment of the present application, when the vehicle is in the second operating condition, the load correction factor is calculated according to the actual load of the vehicle, and the load correction factor is compared with the first set threshold and the second set threshold. When the load correction factor is less than or equal to the first set threshold, the corrected target intake volume is input into the mass flow meter system, and the mass flow meter system is used to control the intake volume of the engine; when the load correction factor is greater than the first set threshold and less than or equal to the second set threshold, the corrected target intake volume is input into the intake manifold pressure system, and the intake manifold pressure system is used to control the intake volume of the engine; when the load correction factor is greater than the second set threshold, the corrected target intake volume is input into the intake manifold pressure system and the mass flow meter system, and the intake manifold pressure system and the mass flow meter system are used to control the intake volume of the engine.

[0048] In an embodiment of the present application, calculating the load correction factor according to the actual load includes: obtaining an estimated load of the engine; and calculating the load correction factor according to the actual load and the estimated load.

[0049] Among them, the estimated load can be determined by indicators such as engine speed.

[0050] It is understandable that the embodiment of the present application obtains the current actual load of the vehicle and determines the estimated load of the engine through indicators such as engine speed, and calculates the load correction factor according to the actual load and the estimated load.

[0051] In an embodiment of the present application, the intake volume of the engine is controlled based on the intake manifold pressure system and the mass flow meter system, including: calculating the intake volume correction coefficient according to the mass flow meter system; and correcting the intake manifold pressure system according to the intake volume correction coefficient.

[0052] It can be understood that in the embodiment of the present application, the intake volume of the engine is controlled based on the intake manifold pressure system and the mass flow meter system. The mass flow meter system is used to calculate the intake volume correction coefficient, and the intake manifold pressure system is corrected using the obtained intake volume correction coefficient to ensure the stability of the intake volume calculation.

[0053] According to the engine intake control method proposed in the embodiment of the present application, the target intake of the engine at the current moment can be calculated according to the required torque of the driver at the current moment, the target intake can be input into at least one of the intake manifold pressure system and the mass flow meter system, and the intake of the engine can be controlled based on at least one of the intake manifold pressure system and the mass flow meter system. The control is carried out by dual systems and dual modes to ensure the accuracy of the intake calculation.

[0054] The following is a further description of the engine intake control method proposed in the embodiment of the present application through a specific embodiment. The embodiment of the present application adopts the control logic of the P system and the HFM system at the same time, which is as follows:

[0055] like Figure 2 As shown, the control module includes a torque control module 201, an HFM / P system control module 202, an air volume correction module 203, and a fuel injection control module 204. According to the torque required by the driver, the required intake volume is calculated after correction, and different control modes are used to control the intake volume according to different vehicle states to improve control accuracy and ensure vehicle combustion stability.

[0056] The embodiments of the present application will be described in detail using the conventional control mode and the aggressive control mode as examples;

[0057] Conventional control modes are divided into multiple situations. According to different driving conditions of the vehicle, they are divided into HFM system control alone, P system control alone, and HFM and P dual system control at the same time, such as Figure 3 The following is a schematic diagram of the conventional control mode flow chart, as follows:

[0058] Step S301: Obtain the current vehicle operating condition and calculate the real-time intake volume according to the driver's real-time torque requirement.

[0059] Step S302: Detect whether the vehicle is in a steady-state operating condition.

[0060] Step S303: Determine whether the vehicle is in a steady-state operating condition.

[0061] If the vehicle is in a steady-state operating condition, the HFM system is used for control, and the HFM system has the advantage of high steady-state control accuracy; if the vehicle is not in a steady-state operating condition, step S304 is performed.

[0062] Step S304: Acquire the actual load, and determine the load correction factor based on the actual load and the estimated load.

[0063] Step S305: According to the load correction factor threshold preset by the control module, the system sets a 2-level threshold, in which the first set threshold is less than the second set threshold. When the load correction factor is less than or equal to the first set threshold, the intake volume is calculated in real time according to the corrected required torque, and the HFM system is used for control; when the load correction factor is greater than the first set threshold and less than or equal to the second set threshold, the intake volume is calculated in real time according to the corrected required torque, and the P system is used for control; when the load correction factor is greater than the second set threshold, the intake volume is calculated in real time according to the corrected required torque, and the HFM and P dual systems are used for control. The above control ensures the accuracy of the intake volume calculation.

[0064] Step S306: Control the engine air intake according to different control modes.

[0065] The aggressive control mode mainly adopts dual system control, the main control adopts P system, and the HFM system is used for correction, such as Figure 4 The following is a schematic diagram of the aggressive control mode process:

[0066] Step S401: Obtain the current vehicle operating condition and calculate the real-time intake volume according to the driver's real-time torque requirement.

[0067] Step S402: Detect whether the vehicle is in an aggressive driving mode.

[0068] Step S403: Determine whether the vehicle is in an aggressive driving mode.

[0069] If the vehicle is not in the aggressive driving mode, the normal system is used for control; if the vehicle is in the aggressive driving mode, step S404 is performed.

[0070] Step S404: The HFM system obtains the target air intake volume and the actual air intake volume in real time, obtains the air intake volume at the first starting angle, obtains the air intake volume at the second angle, and determines the correction factor through the accumulated value of the air intake volume change, as follows:

[0071] Start reading the current intake air volume value from the first starting angle, continue reading the current intake air volume value and calculate the difference with the first angle, accumulate all the differences until the end of the second angle. Calculate the ratio of the accumulated result to the intake manifold pressure r1;

[0072] Start reading the current target intake manifold pressure value from the first starting angle, continue reading the current manifold pressure value and calculate the difference with the first angle, accumulate all the differences until the second angle ends. Calculate the ratio of the accumulated result to the intake manifold pressure r2;

[0073] Calculate the ratio of r1 to r2 and define it as the intake correction coefficient. Calculate the ratio, accumulate the ratios in the entire data collection period and take the average value.

[0074] Step S405: Correct the P system according to the correction coefficient to ensure the accuracy of intake air volume calculation.

[0075] Next, the engine air intake control device proposed according to the embodiment of the present application is described with reference to the accompanying drawings.
