Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to vehicle engineering technology, and particularly to a dehumidification control method, device, equipment and storage medium. BACKGROUND

[0002] With the increasingly serious energy crisis and environmental problems, cleaner and more efficient engines have become a development trend. Hydrogen as a substitute fuel has obvious advantages over other energy sources. Hydrogen as an engine fuel can not only reduce the consumption of fossil energy by motor vehicles but also improve environmental pollution problems.

[0003] The high flammability, low ignition energy, and good uniform combustion of hydrogen fuel make it a good engine fuel, but the drawbacks brought by these characteristics are that the engine is prone to abnormal combustion and high NOx emission. To solve this problem, currently, the industry usually uses an exhaust gas recirculation system (EGR) to reduce the in-cylinder temperature to achieve the effect of inhibiting abnormal combustion, thereby effectively reducing the NOx emission content.

[0004] The exhaust gas discharged by the engine has a high temperature. The exhaust gas is combined with fresh air after passing through the air filter, and then passes through the intercooler and the throttle valve into the intake manifold. The gas cooled by the intercooler is lower than the dew point at a lower environment, forming condensed water, which is prone to condensation. The condensed water is then accumulated at a low point. At this time, the humidity of the air entering the engine cylinder will increase, which will cause engine combustion deterioration, hydrogen consumption increase, speed fluctuation and even engine stall, and will also cause engine wear and oil emulsification, seriously affecting the service life of the engine.

[0005] Therefore, how to avoid too much humidity water vapor from entering the cylinder while ensuring normal operation of the EGR is a technical problem that needs to be solved urgently. SUMMARY

[0021] Optionally, the method further includes determining a first correction coefficient according to the ambient humidity and determining a second correction coefficient according to the ambient temperature.

[0022] After the heat integral value is obtained, the first correction coefficient and / or the second correction coefficient are used to correct the heat integral value to obtain a safe heat integral value.

[0023] When the safe heat integral value is greater than the energy threshold value, the dehumidification function is controlled to be stopped.

[0024] Optionally, the formula used to determine the heat integral value is as follows:

It can be understood that the specific embodiments described herein are only used to explain the application, and not to limit the application. In addition, it should be noted that, in order to facilitate the description, only the parts related to the application are shown in the drawings, not all the structures.

[0043] Embodiment one

[0044] Figure 1 is a dehumidification control method flowchart in the embodiment, referring to Figure 1 , the dehumidification control method comprises:

[0045] S101. When the dehumidification function is activated, the cooling device control amount is determined according to the ambient humidity and the ambient temperature, and the cooling device control amount is used to control the cooling device of the intercooler.

[0046] Figure 2 is an EGR system structure schematic diagram in the embodiment, referring to Figure 2 In the embodiment, the dehumidification function is mainly aimed at the dehumidification of the pipeline inside the EGR system where water is easy to accumulate.

[0047] For example, Figure 2 The structure shown includes an intercooler 100, an intake flow meter 200, a compressor 300, an EGR valve 400, an EGR cooler 500, a turbine 600, and a plurality of patch temperature sensors (101-103).

[0048] The composition, connection mode, and working mode of the EGR system are the same as those in the prior art, and the specific content is not described in detail.

[0049] Figure 2 In the structure shown, the position of the intercooler pipeline 1000 is set as an area prone to water accumulation, and the patch temperature sensor is arranged at the position of the intercooler pipeline 1000.

[0050] For example, in this embodiment, a 3D model of the EGR system can be established, and the area prone to water accumulation (which is generally at the position of a pipeline bend or a lower part through which the gas flow after mixing of exhaust gas and fresh air) can be determined through simulation tests.

[0051] In this embodiment, the dehumidification function is specifically used to prevent water accumulation or gas condensation in the area prone to water accumulation.

[0052] In this embodiment, the intercooler is provided with a cooling device, and the type of the cooling device is not limited, which can be a liquid cooling device or an air (wind) cooling device.

[0053] In this embodiment, the cooling device control quantity is specifically used to control the flow rate of the refrigerant passing through the cooling device, thereby adjusting the temperature after intercooling of the intercooler.

[0054] Specifically, the cooling device control quantity is specifically used to increase the temperature after intercooling corresponding to the intercooler by adjusting the flow rate of the refrigerant.

[0055] In this embodiment, the way of determining the cooling device control quantity by using the ambient humidity and the ambient temperature is not limited.

[0056] For example, the cooling device control quantity corresponding to the ambient humidity and the ambient temperature can be determined by a lookup table through a preset matching relationship, wherein the preset matching relationship can be determined by calibration tests, simulation tests, or the like.

[0057] Alternatively, the ambient humidity and the ambient temperature can be used as inputs, and a preset function model can be used to determine the cooling device control quantity, wherein the function model can be determined by simulation tests, or a trained neural network model, a machine learning model, or the like.

[0058] In this embodiment, it is provided that the EGR system is simultaneously controlled to stop working when the dehumidification function is activated.

[0059] S102. Obtain the temperature after intercooling and the compressor inlet air mass flow when the dehumidification function is activated, and integrate the temperature after intercooling and the compressor inlet air mass flow with respect to time to obtain a heat integral value.

[0060] Reference Figure 2 In this embodiment, the temperature after intercooling can be obtained by measuring (one or more of 101-103) by a patch temperature sensor, and the compressor inlet air mass flow can be obtained by measuring by the inlet air flow 200.

[0061] For example, in this embodiment, the temperature after intercooling and the compressor inlet air mass flow are both related to time, and the form of the integral formula including the temperature after intercooling and the compressor inlet air mass flow is not limited, which can be freely set according to design requirements.

[0062] S103. When the heat integral value is greater than the energy threshold value, control the dehumidification function to stop.

[0063] In this embodiment, the value of the energy threshold value is related to the form of the integral formula including the temperature after intercooling and the compressor inlet air mass flow, and the specific value of the energy threshold value can be determined by calibration test or simulation test.

[0064] In this embodiment, the value of the energy threshold value is set to satisfy: when the heat integral value is greater than the energy threshold value, the temperature of the easy water accumulation area (such as the position of the intercooler pipeline 1000) is greater than the dew point temperature;

[0065] The dew point temperature represents the temperature at which the gaseous water contained in the air needs to be reduced to reach saturation and condense into liquid water under a fixed air pressure.

[0066] In this embodiment, when the dehumidification function is controlled to stop, the EGR system is also controlled to start working.

[0067] In this scheme, when it is necessary to reduce the humidity of water vapor, the dehumidification function is activated, and when the dehumidification function is activated, the temperature of the intercooler is raised by controlling the cold zone device of the intercooler, and when the temperature of the intercooler rises to a certain temperature (dew point temperature), the water vapor in the air no longer condenses on the intercooler pipeline, and the humidity of the air is reduced. The air at this humidity enters the engine cylinder, which can avoid the problem of engine combustion deterioration;

[0068] Since the dew point temperature is related to many factors such as environmental temperature and engine operating conditions, in this scheme, the heat integral value is determined by the temperature after intercooling corresponding to the change of the temperature of the intercooler and the compressor inlet air mass flow related to the change of the temperature of the intercooler, and whether the temperature of the intercooler exceeds the dew point temperature is determined by the heat integral value, which can effectively quantify the dew point temperature, and then effectively determine the time when the temperature exceeds the dew point temperature, avoid the EGR system to be closed for a long time, and ensure the utilization rate of the EGR system;

[0069] In addition, when the temperature of the intercooler is increased when the dehumidification function is activated, the temperature of the gas at low temperature (passing through the intercooler) is also increased, thereby avoiding the problem of excessive torque and torque accuracy deviation caused by excessive intake air density.

[0070] In Figure 1 Based on the scheme shown, in an implementable scheme, it is determined whether to activate the dehumidification function according to the ambient humidity, the ambient temperature, the engine coolant temperature, and the temperature after intercooling.

[0071] Specifically, in the present scheme, the ambient humidity, the ambient temperature, the engine coolant temperature, and the temperature after intercooling are obtained.

[0072] If the ambient humidity is greater than a first threshold value, the ambient temperature is greater than a second threshold value, the engine coolant temperature is greater than a third threshold value, and the temperature after intercooling is not greater than a fourth threshold value, the dehumidification function is activated.

[0073] For example, in the present scheme, the first threshold value, the second threshold value, the third threshold value, and the fourth threshold value are determined through simulation tests.

[0074] In the present scheme, by combining various factors related to water vapor condensation, it can be accurately predicted when water vapor condenses in large quantities, and the dehumidification function can be activated in a timely manner.

[0075] In Figure 1 Based on the scheme shown, in an implementable scheme, the energy threshold value is determined according to the first two-dimensional MAP table.

[0076] The two dimensions of the first two-dimensional MAP table are the temperature after intercooling and the ambient temperature.

[0077] The energy threshold value is the lookup value of the first two-dimensional MAP table corresponding to the temperature after intercooling and the ambient temperature at the time when the dehumidification function is activated.

[0078] In the present scheme, the first two-dimensional MAP table is determined through calibration tests, wherein, during calibration, the lookup value can be determined according to the temperature variation curve of the water accumulation prone area, and the Figure 2 For example, the first two-dimensional MAP table can be calibrated in the following manner:

[0079] A set of temperatures after intercooling (greater than -30℃ and less than 50℃) and ambient temperatures (greater than -30℃) are set.

[0080] For each pair of temperature after intercooling and ambient temperature, the engine is controlled to be in an idle operating condition, and the EGR system is controlled to operate in a conventional manner (i.e., the dehumidification control method described in the present embodiment is not performed) under the temperature after intercooling and the ambient temperature.

[0081] obtaining a temperature curve of the temperature sensor (one or more of 101-103), determining a last inflection point before a specified temperature on the temperature curve;

[0082] integrating heat from a start time of the calibration test to a time corresponding to the inflection point as an energy threshold value;

[0083] The calculation method of the heat integration value is the same as the method for determining the heat integration value when the dehumidification control method is executed.

[0084] In Figure 1 On the basis of the scheme shown, in an implementable scheme, the cooling device control quantity is determined according to the second two-dimensional MAP table;

[0085] The two dimensions of the second two-dimensional MAP table are the ambient temperature and the ambient humidity.

[0086] The cooling device control quantity is the second two-dimensional MAP table lookup value corresponding to the ambient temperature and the ambient humidity at the time when the dehumidification function is activated.

[0087] For example, in this scheme, the second two-dimensional MAP table is determined through a calibration test, wherein the second two-dimensional MAP table lookup value after calibration satisfies: when the (intercooler) cooling device is controlled using the corresponding second two-dimensional MAP table lookup value under different ambient temperature and ambient humidity conditions, the rate of temperature rise of the (intercooler) is substantially the same.

[0088] In Figure 1 On the basis of the scheme shown, in an implementable scheme, the second two-dimensional MAP table lookup value includes a first type of lookup value and a second type of lookup value;

[0089] The first type of lookup value is a calibration test value, and the second type of lookup value is an empirical value.

[0090] In this scheme, the first type of lookup value can be determined as follows:

[0091] A set of intercooled temperatures (intercooled temperature greater than -30℃ and less than 50℃) and ambient temperatures (greater than -30℃) are set;

[0092] For each pair of intercooled temperature and ambient temperature, the engine is controlled to be in an idle operating condition under the intercooled temperature and ambient temperature, and the EGR system is controlled to operate in a conventional manner (i.e., the dehumidification control method described in the embodiments of the present application is not executed);

[0093] Obtain the temperature curves of the patch temperature sensor (101~103), determine the temperature curve with the slowest temperature rise, determine the last inflection point on the curve before the temperature rises to 50℃, determine the heat integral value from the start time to the time corresponding to the inflection point, and use this value as the corresponding first-type lookup table value.

[0094] If the highest temperature of all temperature curves exceeds 50℃, but there is no inflection point in any temperature curve, then determine the temperature curve with the slowest temperature rise, determine the heat integral value at the corresponding moment from the starting time to the temperature of 50℃, and use this value as the corresponding first-type lookup table value.

[0095] If the highest temperature of all temperature curves does not exceed 50℃, then the empirical value is used as the corresponding second-type lookup value.

[0096] exist Figure 1 Based on the scheme shown, in one possible implementation, after determining the heat integral value, the method further includes determining a first correction factor based on the ambient humidity and a second correction factor based on the ambient temperature.

[0097] The integral value of heat is corrected by the first correction factor and / or the second correction factor to obtain the safe integral value of heat.

[0098] When the safe heat integral value exceeds the energy threshold, the dehumidification function will be stopped.

[0099] For example, since ambient humidity and ambient temperature have a certain impact on dew point temperature, the heat integral value is determined by using the temperature after intercooling and the compressor intake volume. The heat integral value is then corrected by the first correction coefficient and the second correction coefficient to obtain a safe heat integral value. The safe heat integral value is compared with the energy threshold to determine whether to exit the dehumidification function. This can effectively ensure that the dehumidification function stops when the temperature in the area prone to water accumulation exceeds the dew point temperature, thereby ensuring the effectiveness of dehumidification.

[0100] For example, in this solution, the first correction factor and the second correction factor corresponding to different ambient humidity and different ambient temperature are both values ​​greater than 1;

[0101] The specific values ​​of the first correction factor and the second correction factor can be determined through calibration tests.

[0102] For example, in this scheme, the first correction coefficient can be as follows: Figure 3 As shown, the second correction factor can be as shown in Table 1.

[0103] Table 1

[0104]

[0105] exist Figure 1On the basis of the shown solution, in an implementable solution, the formula for determining the heat integral is:

[0106]

[0107] wherein, is the heat integral, is the specific heat capacity of air, is the temperature after intercooling, is the compressor intake air volume.

[0108] Exemplarily, in the embodiment, the solutions corresponding to any of the above dehumidification control methods can be freely arranged and combined, Figure 4 is another flowchart of the dehumidification control method in the embodiment, referring to Figure 4 For example, in an implementable solution, the dehumidification control method comprises:

[0109] S201. Determine whether to activate the dehumidification function according to the ambient humidity, the ambient temperature, the engine coolant temperature, and the temperature after intercooling.

[0110] In the solution, when the ambient humidity is greater than the humidity threshold value, the ambient temperature is greater than -30℃, the engine coolant temperature is greater than 60℃, and the temperature after intercooling is not greater than -30℃, the dehumidification function is activated.

[0111] S202. When the dehumidification function is activated, determine the energy threshold value according to the first two-dimensional MAP table.

[0112] In the solution, when the dehumidification function is activated, the temperature after intercooling and the ambient humidity are obtained, and the energy threshold value is determined according to the temperature after intercooling and the ambient temperature at the current time by using the first two-dimensional MAP table.

[0113] S203. When the dehumidification function is activated, determine the cooling device control amount according to the second two-dimensional MAP table.

[0114] In the solution, when the dehumidification function is activated, the ambient humidity and the ambient temperature are obtained, and the cooling device control amount is determined according to the ambient humidity and the ambient temperature at the current time by using the second two-dimensional MAP table.

[0115] In the solution, the cooling device is set to be a liquid cooling device, and the cooling device control amount is set to be a duty cycle control signal for a flow pump of the liquid cooling device.

[0116] Exemplarily, in the solution, the cooling device can be designed to adopt an independent liquid cooling circulation system to cool the intercooler, or to cool the intercooler by means of the engine cooling system.

[0117] In the solution, when it is raining or snowing, the cooling device control amount can also be determined by the detection value of the rain sensor;

[0118] Specifically, when the rain sensor detects that the rainfall is greater than the rainfall threshold, the cooling device control amount is selected as the maximum value (i.e., the duty cycle of the duty cycle signal is 0) to make the intercooler quickly warm up.

[0119] S204. The cooling device of the intercooler is controlled by the cooling device control amount to make the intercooler warm up.

[0120] S205. The temperature after the intercooling and the air compressor intake air amount after the dehumidification function is activated are obtained, and the temperature after the intercooling and the engine intake air amount are integrated with respect to time to obtain a heat integral value.

[0121] In this scheme, the heat integral value is determined by the following formula:

[0122]

[0123] In the formula, the heat integral, the specific heat capacity of air, the temperature after the intercooling, the air compressor intake air amount.

[0124] In this scheme, the heat integral value and the air compressor intake air amount are related, the integrator output is consistent with the change direction of ;

[0125] Since not all of the energy generated by the intake air is used for heating, the air compressor intake air amount needs to be corrected;

[0126] wherein the air compressor intake air amount can be corrected by an intake air amount correction coefficient, and the intake air amount correction coefficient decreases with the increase of , that is, The greater the heating energy loss rate is, the greater the

[0127] S206. The heat integral value is corrected by the first correction coefficient and the second correction coefficient to obtain a safe heat integral value.

[0128] In this scheme, the ambient humidity when the dehumidification function is activated is obtained, and the first correction coefficient is determined according to the current ambient humidity by Figure 3 The ambient temperature when the dehumidification function is activated is obtained, and the second correction coefficient is determined according to the current ambient temperature by Table 1.

[0129] In this scheme, the safe heat integral value is determined by the following formula:

[0130]

[0131] In the formula, the safe heat integral value, is a first correction coefficient, is a second correction coefficient, is a heat integral value.

[0132] S207. When the safety heat integral value is greater than the energy threshold value, the dehumidification function is controlled to stop.

[0133] In the present scheme, when the dehumidification function is stopped, the cooling device of the intercooler works according to the original control strategy, and the control strategy configured is the same as that of the prior art, and the specific content is not described in detail.
