Description

Technical Field

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

[0002] With the development of the automobile industry, the technical requirements for automobile engines are also constantly increasing. In particular, the market has put forward higher standards for engines in terms of power performance, fuel economy and design universality. In order to meet these requirements, engine miniaturization has become an important development trend. In this context, how to reduce the size of the engine while ensuring its performance has become one of the research focuses.

[0003] For gasoline engines used in passenger cars, the intake volume and its efficiency are directly related to whether the engine can achieve the expected power and economy goals. In order to improve the intake efficiency, it is usually necessary to introduce some new technical means based on traditional engine technology, such as turbocharging and EGR (Exhaust Gas Recirculation).

[0004] Turbocharging technology uses the exhaust gas from the engine to drive the turbine, which in turn compresses the intake air to increase the intake volume and improve the engine's efficiency. However, while turbocharging improves intake efficiency, it also increases the temperature of the intake air. On the other hand, exhaust gas recirculation technology reduces nitrogen oxide emissions by reintroducing part of the high-temperature, high-humidity exhaust gas that has been burned into the cylinder. Although this method helps reduce pollutant emissions, it further exacerbates the problem of intake temperature.

[0005] Too high intake air temperature will have an adverse effect on the intake efficiency of the engine, so measures must be taken to effectively cool the intake air. However, during the cooling process, high-temperature and high-humidity gas is prone to condensation when it encounters low temperature, especially in an environment with high relative humidity, where a large amount of moisture in the exhaust gas will precipitate to form condensed water. The presence of this condensed water will not only interfere with the normal operation of the engine, but may also affect the stability and efficiency of the combustion process, and even cause the engine to misfire. Summary of the invention

[0027] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0028] The following describes the control method, device, vehicle, medium and product of the intake system 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 the presence of condensed water leads to low engine combustion efficiency, instability and even misfire, the present application provides a control method for the intake system, in which the target EGR rate and target cooling water temperature of the exhaust gas recirculation system EGR of the engine are determined based on the engine operating parameters and the intake humidity of the intake system, and finally the intake system and EGR are controlled according to the target EGR rate and the target cooling water temperature. Thereby, the risk of engine misfire is avoided and the thermal efficiency and fuel economy of the engine are improved. Thus, the problem that the presence of condensed water leads to low engine combustion efficiency, instability and even misfire is solved.

[0029] Specifically, Figure 1 A flow chart of a method for controlling an air intake system provided in an embodiment of the present application.

[0030] like Figure 1 As shown, the control method of the intake system includes the following steps:

[0031] In step S101, the operating parameters of the engine and the intake air humidity of the intake system are obtained.

[0032] Among them, the operating parameters of the engine are usually obtained through various sensors installed on the engine, which will be described in detail below and will not be repeated here; the intake humidity of the intake system refers to the moisture content in the air before entering the engine combustion chamber, which can be obtained through a humidity sensor.

[0033] It is understandable that the embodiments of the present application can obtain the operating parameters of the engine and the intake humidity of the intake system through sensors and the like.

[0034] In the embodiment of the present application, the operating parameters of the engine include at least one of the engine speed, the engine load and the engine temperature.

[0035] It is understandable that the operating parameters of the engine in the embodiment of the present application include at least one of the engine speed, engine load and engine temperature, which can be obtained through corresponding sensors. For example, the engine speed can be obtained through a speed sensor, and the engine load can be calculated by measuring the throttle position and torque through a throttle position sensor, a torque sensor, etc. This achieves real-time measurement of intake humidity, relaxes the control of the EGR rate, and improves the utilization rate of exhaust gas.

[0036] In step S102, a target EGR rate and a target cooling water temperature of an exhaust gas recirculation system EGR of the engine are determined based on the operating parameters of the engine and the intake air humidity of the intake system.

[0037] The target EGR rate and the target cooling water temperature are used to control the amount of condensed water released from the intake system to be within a target range. The target range of the amount of condensed water released from the intake system is a range in which the amount of condensed water released has no effect on engine performance. It is set according to actual needs and is not specifically limited here.

[0038] It can be understood that the target EGR rate refers to the optimal exhaust gas recirculation ratio set by the engine control system according to the current operating conditions, and the target cooling water temperature refers to the ideal temperature of the coolant in the engine cooling system under the current operating conditions. The embodiment of the present application can determine the values ​​of the two through the operating parameters of the engine and the intake humidity of the intake system, which are used to control the precipitation amount of condensed water in the intake system within the target range.

[0039] In an embodiment of the present application, based on the operating parameters of the engine and the intake humidity of the intake system, the target EGR rate and target cooling water temperature of the exhaust gas recirculation system EGR of the engine include: obtaining a correspondence table between the operating parameters and the intake humidity and the EGR rate and the cooling water temperature; using the operating parameters of the engine and the intake humidity of the intake system as an index, querying the correspondence table to determine the target EGR rate and target cooling water temperature of the exhaust gas recirculation system EGR of the engine.

[0040] Among them, the calibration method of the corresponding relationship table between the operating parameters and the intake air humidity, the EGR rate and the cooling water temperature is described in detail below and will not be repeated here.

[0041] It can be understood that the embodiment of the present application obtains and consults the correspondence table between operating parameters and intake air humidity and EGR rate and cooling water temperature, and determines the target EGR rate and target cooling water temperature of the engine's exhaust gas recirculation system EGR through the current engine operating parameters and the intake air humidity of the intake system.

[0042] In an embodiment of the present application, before obtaining the correspondence table of operating parameters and intake air humidity, EGR rate and cooling water temperature, it also includes: obtaining the target range of the precipitation amount of condensed water in the intake system; calibrating the correspondence table of operating parameters and intake air humidity, EGR rate and cooling water temperature, and during the calibration process, maintaining the precipitation amount of condensed water in the intake system within the target range.

[0043] It can be understood that the correspondence table of operating parameters and intake humidity with EGR rate and cooling water temperature in the embodiment of the present application needs to be calibrated in advance, and the precipitation amount of condensed water in the intake system needs to be controlled within the target range during the calibration process. Therefore, in the embodiment of the present application, the EGR rate and cooling water temperature control under various humidity conditions can be calibrated, which effectively shortens the calibration development time, reduces the calibration workload, improves work efficiency, and gets rid of the dependence of the calibration parameters on actual weather and other environmental conditions, making the control strategy more stable and reliable.

[0044] In step S103, the intake system and EGR are controlled according to the target EGR rate and the target cooling water temperature.

[0045] It can be understood that the embodiment of the present application can control the EGR to adjust to the target EGR rate and control the intake system to adjust the temperature of the cooling water to reach the target cooling water temperature based on the acquired EGR rate and cooling water temperature.

[0046] In an embodiment of the present application, the intake system and EGR are controlled according to a target EGR rate and a target cooling water temperature, including: controlling an EGR rate control valve of the EGR according to the target EGR rate; and controlling an intake intercooler, a water pump and a cooler of the intake system according to the target cooling water temperature.

[0047] Among them, the opening size of the EGR rate control valve can adjust the EGR rate; the main function of the intake intercooler of the intake system is to reduce the intake temperature during the engine intake process, and the EGR water pump and cooler are mainly used to drive the coolant circulation to maintain the cooling effect.

[0048] It can be understood that the embodiment of the present application adjusts the EGR rate by adjusting the opening size of the EGR rate control valve to achieve the target EGR rate; and adjusts the cooling water temperature by controlling the intake intercooler, EGR water pump and cooler of the intake system to achieve the target cooling water temperature.

[0049] In an embodiment of the present application, an intake intercooler, an EGR water pump and a cooler of an intake system are controlled according to a target cooling water temperature, including: respectively determining target operating parameters of the intake intercooler, the water pump and the cooler according to the target cooling water temperature; and controlling the operation of the intake intercooler, the water pump and the cooler according to the target operating parameters of the intake intercooler, the water pump and the cooler.

[0050] Among them, the target operating parameters of the intake air intercooler, water pump and cooler are determined by the target cooling water temperature. The specific determination method can be through a correspondence table calibrated in advance by experiments. After obtaining the target cooling water temperature, the corresponding relationship table is used to determine the target operating parameters of the intake air intercooler, water pump and cooler at the target cooling water temperature. The correspondence table is set according to the specific experimental situation and is not specifically limited here.

[0051] It can be understood that the embodiment of the present application adjusts the intake intercooler, EGR water pump and cooler of the intake system. First, a correspondence table between the target cooling water temperature and the target operating parameters of the intake intercooler, water pump and cooler is obtained, and the target operating parameters of the intake intercooler, water pump and cooler are determined respectively through the corresponding relationship. The control machine intake intercooler, water pump and cooler are adjusted according to their respective target operating parameters to achieve the expected working state, and finally the cooling water temperature reaches the target cooling water temperature.

[0052] According to the control method of the intake system proposed in the embodiment of the present application, the engine operating parameters and the intake humidity of the intake system are obtained, and the target EGR rate and target cooling water temperature of the exhaust gas recirculation system EGR of the engine are determined based on the two, and finally the intake system and EGR are controlled according to the target EGR rate and target cooling water temperature. Thereby, the risk of engine misfire is avoided and the thermal efficiency and fuel economy of the engine are improved.

[0053] The control method of the intake system is further described below through a specific embodiment.

[0054] The sensor application system layout diagram of the intake system control method provided in this embodiment is as follows Figure 2 As shown, a humidity sensor 201 is newly added in the hardware, and the signal processing of the ECU's recognition and conversion of humidity sensor signals, as well as system control logic and strategy are added in the software.

[0056] The working process of this embodiment is as follows: the controller first obtains the intake humidity signal from the humidity sensor 201, converts and identifies the humidity signal, and then couples and calculates the humidity signal with the EGR rate of the calibration strategy and the temperature signal of the cooler, such as Figure 4 As shown, a condensate-controllable EGR rate and cooler temperature control are finally obtained, so that the condensate of the entire intake system of the engine can be controlled and the engine combustion stability is ensured.

[0057] The following example illustrates the coupling calculation process:

[0058] 1) The controller receives information from sensors indicating that the engine speed is 2000 rpm, the engine load is 30%, the engine temperature is 90 degrees, and the air humidity is 70%;

[0059] 2) For the data of the temperature sensor 201, before the control, the calibration matrix data 1 or 3 will be selected under the conditions that have been calibrated and solidified in the development stage. The matrix data 1 or 3 respectively corresponds to a set of EGR rate of 20% and the EGR cooling water temperature of 85 degrees;

[0060] 3) The controller sends the output signal corresponding to the matrix to the EGR rate control valve 207 and the water pump to achieve the corresponding EGR rate and cooling water temperature, thereby achieving the maximum EGR utilization rate in this state and stabilizing the engine combustion.

[0067] In the embodiment of the present application, the operating parameters of the engine include at least one of the engine speed, the engine load and the engine temperature.

[0068] In the embodiment of the present application, the control module 303 is further used to: control the EGR rate control valve of the EGR according to the target EGR rate; and control the intake intercooler, the EGR water pump and the cooler of the intake system according to the target cooling water temperature.

[0069] In an embodiment of the present application, an intake intercooler, an EGR water pump and a cooler of an intake system are controlled according to a target cooling water temperature, including: respectively determining target operating parameters of the intake intercooler, the water pump and the cooler according to the target cooling water temperature; and controlling the operation of the intake intercooler, the water pump and the cooler according to the target operating parameters of the intake intercooler, the water pump and the cooler.
