Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an engine intake air volume control method, device, vehicle, storage medium, and product. Background Technology

[0002] Currently, vehicle air intake control mainly uses intake manifold pressure (P system) or intake flow rate, i.e., HFM (Hot Film Air Meter) system, which provides high control accuracy under steady-state conditions.

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

[0004] In related technologies, vehicle control uses either a P system or an HFM system. The former has better transient response but poorer control accuracy, while the latter has higher steady-state control accuracy but poorer transient response. When the engine is in transient operation, the actual intake volume fluctuates greatly due to the effects of throttling, eddies, and turbulence in the intake manifold and throttle valve. This can interfere with the reading accuracy of pressure sensors and flow meters, leading to the inability to accurately control the intake volume. Poor transient control of the entire vehicle not only affects the driving experience but can also cause serious damage to the vehicle. Summary of the Invention

[0026] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0027] The engine intake air volume control method, device, vehicle, storage medium, and product according to embodiments of this application are described below with reference to the accompanying drawings. Addressing the problem mentioned in the background art that when the engine is under transient operating conditions, throttling, eddy currents, and turbulence within the intake manifold and throttle valve can cause significant fluctuations in the actual intake air volume, thereby affecting the measurement accuracy of pressure sensors and flow meters and resulting in inaccurate intake air volume control, this application provides an engine intake air volume control method. In this method, the target intake air volume of the engine at the current moment is calculated based on the driver's current torque demand. The target intake air volume is input to at least one of an intake manifold pressure system and a mass flow meter system. The engine intake air volume is controlled based on at least one of the intake manifold pressure system and the mass flow meter system. Dual-system, dual-mode control is employed to ensure the accuracy of the intake air volume calculation. Therefore, this solves the problem that when the engine is under transient operating conditions, throttling, eddy currents, and turbulence within the intake manifold and throttle valve can cause significant fluctuations in the actual intake air volume, thereby affecting the measurement accuracy of pressure sensors and flow meters and resulting in inaccurate intake air volume control.

[0028] Specifically, Figure 1 This is a flowchart illustrating an engine intake air volume control method provided in an embodiment of this application.

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

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

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

[0032] It is understood that the embodiments of this application can obtain the driver's required torque by detecting the degree to which the driver presses the accelerator pedal.

[0033] In step S102, the target intake volume of the engine at the current moment is calculated based on the driver's required torque at the current moment.

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

[0035] It is understood that, in the embodiments of this application, the target intake volume of the engine at the current moment can be calculated by EMS based on the engine characteristic curve and the driver's required torque at the current moment.

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

[0037] The intake manifold pressure system, also known as the P system, is used to measure the internal pressure of the engine's intake manifold. Its main working principle is to calculate the intake air volume by measuring pressure changes inside the engine or intake system. It relies heavily on the accuracy and response speed of the pressure sensor. Under high flow or high pressure conditions, its accuracy and stability are inferior to the mass flow meter system, and it requires additional pressure calibration and compensation to adapt to different operating conditions. The mass flow meter system, on the other hand, measures the mass flow rate of air entering the engine. By measuring the mass of air entering the engine, it determines the engine's intake air volume. This type of flow meter has high durability, stability, and accuracy, can adapt to high-pressure and high-flow operating conditions, and does not require additional pressure and temperature compensation.

[0038] It is understood that, in the embodiments of this application, the calculated target intake air volume of the engine at the current moment can be input into at least one of the intake manifold pressure system and the mass flow meter system according to some judgment method. The method of judging whether to input into 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 into at least one of the intake manifold pressure system and the mass flow meter system, the intake air 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 this embodiment of the application, controlling the intake air volume of the engine based on at least one of the intake manifold pressure system and the mass flow meter system includes: identifying the current driving mode of the vehicle; if the current driving mode is a first driving mode, determining at least one of the intake manifold pressure system and the mass flow meter system to control the intake air volume of the engine based on the current operating conditions; if the current driving mode is a second driving mode, controlling the intake air volume of the engine based on the intake manifold pressure system and the mass flow meter system.

[0040] The first driving mode is the normal control mode; the second driving mode is the aggressive control mode.

[0041] It is understood that the embodiments of this application can identify whether the vehicle is in a first driving mode, i.e., a normal control mode, or a second driving mode, i.e., an aggressive control mode. When the vehicle is identified as being in the first driving mode, at least one of the intake manifold pressure system and the mass flow meter system is determined based on the current operating conditions to control the engine's intake air volume. This process will be described in detail below and will not be repeated here. When the vehicle is identified as being in the second driving mode, the intake air volume of the engine is controlled jointly by the intake manifold pressure system and the mass flow meter system.

[0042] In this embodiment of the application, determining the intake air volume of the engine based on at least one control of the intake manifold pressure system and the mass flow meter system based on the current operating conditions includes: if the current operating condition is a first operating condition, then controlling the intake air volume of the engine based on the mass flow meter system; if the current operating condition is a second operating condition, then determining the intake air volume of the engine based on at least one control of the intake manifold pressure system and the mass flow meter system according to the actual load of the vehicle.

[0043] The first operating condition is a steady-state operating condition; the second operating condition is a non-steady-state operating condition; whether the vehicle is in a steady-state operating condition can be judged by indicators such as vehicle speed and acceleration, engine speed and accelerator pedal position; 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 condition.

[0044] It is understood that in the embodiments of this application, when the vehicle is detected to be 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 air 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 air volume of the engine based on the actual load of the vehicle. The details will be described below and will not be repeated here.

[0045] In this embodiment, determining the intake air volume of the engine based on at least one control system of the intake manifold pressure system and the mass flow meter system according to the actual load of the vehicle includes: calculating a load correction factor based on the actual load, correcting the required torque based on the load correction factor, and correcting the target intake air volume based on the corrected required torque; if the load correction factor is less than or equal to a first set threshold, inputting the corrected target intake air volume into the mass flow meter system, and controlling the engine intake air volume 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, inputting the corrected target intake air volume into the intake manifold pressure system, and controlling the engine intake air volume 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, inputting the corrected target intake air volume into the intake manifold pressure system and the mass flow meter system, and controlling the engine intake air volume based on the mass flow meter system and the mass flow meter system.

[0046] The first and second set thresholds are load correction factor values ​​set according to actual requirements. They 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 is understood that, in the embodiments of this application, when the vehicle is in the second operating condition, a load correction factor is calculated based on the actual load of the vehicle, and the load correction factor is compared with a first set threshold and a second set threshold. When the load correction factor is less than or equal to the first set threshold, the corrected target intake air volume is input into the mass flow meter system, and the mass flow meter system is used to control the engine's intake air volume. 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 air volume is input into the intake manifold pressure system, and the intake manifold pressure system is used to control the engine's intake air volume. When the load correction factor is greater than the second set threshold, the corrected target intake air volume is input into both the intake manifold pressure system and the mass flow meter system, and both systems are used to control the engine's intake air volume.

[0048] In this embodiment of the application, calculating the load correction factor based on the actual load includes: obtaining the estimated load of the engine; and calculating the load correction factor based on the actual load and the estimated load.

[0049] The estimated load can be determined using indicators such as engine speed.

[0050] It is understood that the embodiments of this application obtain the current actual load of the vehicle and determine the estimated load of the engine through indicators such as engine speed, and calculate the load correction factor based on the actual load and the estimated load.

[0051] In this embodiment of the application, controlling the intake air volume of the engine based on the intake manifold pressure system and the mass flow meter system includes: calculating the intake air volume correction coefficient according to the mass flow meter system; and correcting the intake manifold pressure system according to the intake air volume correction coefficient.

[0052] It is understood that in this embodiment of the application, the intake air volume of the engine is controlled by two systems: the intake manifold pressure system and the mass flow meter system. The mass flow meter system is used to calculate the intake air volume correction coefficient, and the obtained intake air volume correction coefficient is used to correct the intake manifold pressure system to ensure the stability of the intake air volume calculation.

[0053] According to the engine intake volume control method proposed in the embodiments of this application, the target intake volume of the engine at the current moment can be 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 mass flow meter system, and the engine intake volume is controlled based on at least one of the intake manifold pressure system and mass flow meter system. The dual system and dual mode control is adopted to ensure the accuracy of intake volume calculation.

[0054] The engine intake air volume control method proposed in this application is further described below through a specific embodiment. This embodiment uses control logic from both the P system and the HFM system, as detailed below:

[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. Based on the driver's required torque, the required air volume is calculated after correction. Different control modes are used to control the air volume according to different vehicle conditions to improve control accuracy and ensure vehicle combustion stability.

[0056] The embodiments in this application will be described in detail using conventional control mode and radical control mode as examples;

[0057] Conventional control modes are divided into several scenarios, depending on the vehicle's different driving conditions: HFM system-only control, P system-only control, and simultaneous control of both HFM and P systems. Figure 3 The diagram shown is a schematic of the conventional control mode flow, as detailed below:

[0058] Step S301: Obtain the current vehicle operating conditions and calculate the real-time intake volume based on the driver's real-time torque demand.

[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, which has the advantage of high steady-state control accuracy; if it is not in a steady-state operating condition, proceed to step S304.

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

[0063] Step S305: The system determines the intake volume based on the preset load correction factor threshold of the control module. The system has two threshold levels, with the first threshold being less than the second threshold. When the load correction factor is less than or equal to the first threshold, the intake volume is calculated in real-time based on the corrected required torque, and control is performed using an HFM system. When the load correction factor is greater than the first threshold but less than or equal to the second threshold, the intake volume is calculated in real-time based on the corrected required torque, and control is performed using a P system. When the load correction factor is greater than the second threshold, the intake volume is calculated in real-time based on the corrected required torque, and control is performed using both HFM and P systems. This control method ensures the accuracy of the intake volume calculation.

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

[0065] The aggressive control mode primarily employs a dual-system control, with a P-system as the main control and an HFM-system used for correction, such as... Figure 4 The diagram below illustrates the radical control mode flow.

[0066] Step S401: Obtain the current vehicle operating conditions and calculate the real-time intake volume based on the driver's real-time torque demand.

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

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

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

[0070] Step S404: The HFM system acquires the target intake volume and the actual intake volume in real time, acquires the intake volume at the first starting angle, acquires the intake volume at the second angle, and determines the correction factor by accumulating the intake volume changes, as follows:

[0071] Starting from the first initial angle, the intake air volume value is read continuously, and the difference between the current intake air volume value and the value at the first angle is calculated. All differences are accumulated until the second angle is reached. The accumulated result is then compared with the intake manifold pressure, and the ratio r1 is calculated.

[0072] Starting from the first initial angle, read the current target intake manifold pressure value, continuously read the current manifold pressure value and calculate the difference with the first angle, accumulate all differences until the second angle ends. Calculate the ratio r2 between the accumulated result and the intake manifold pressure.

[0073] Calculate the ratio of r1 to r2 and define it as the intake air volume correction factor. Then, calculate the ratio, accumulate the ratios over the entire data acquisition period, and take the average value.

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