Description

Technical Field

[0001] The present invention relates to the technical field of intercooler control, and particularly relates to a control method, system, readable storage medium and computer for an automotive intercooler. Background Art

[0002] With the rapid development of technology and the improvement of people's living standards, automobiles have become an indispensable part of people's daily travel. Due to the popularity of automobiles, various high-power devices have begun to appear on vehicles, which requires further improvement of the power of automobile engines.

[0003] The intercooler, as one of the accessories for turbocharging, plays a significant role in reducing the temperature of the high-temperature air after supercharging, thereby reducing the heat load of the engine, increasing the intake air volume, and further increasing the power of the engine.

[0004] Currently, the intercooler of a vehicle is usually manufactured directly according to the design parameters of the intercooler simulated or calculated based on the corresponding model before the vehicle leaves the factory, and then the prepared intercooler is applied to the corresponding vehicle. However, the relevant design of the intercooler before leaving the factory does not fully consider the vehicle state, but reduces the heat load through the parameters at the time of leaving the factory, resulting in an increase in vehicle energy consumption. At the same time, it also makes the intercooler unable to allocate a reasonable heat dissipation strategy during vehicle operation. Moreover, reducing the heat load through the parameters at the time of leaving the factory will keep the intercooler in a high-load state. As the usage time increases, the heat dissipation effect of the turbocharging will not reach the state at the time of leaving the factory, thereby affecting the performance of the vehicle.

[0020] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific Embodiments

[0021] For ease of understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention is thorough and complete.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Embodiment 1 Please refer to Figure 1 , which shows the control method of the automotive intercooler in the first embodiment of the present invention. The method specifically includes steps S101 to S105: S101, obtaining the external environment information of the vehicle and the current temperature of the engine, and determining the current working condition of the vehicle according to the external environment information and the current temperature of the engine; Further, please refer to Figure 2 , the step S101 specifically includes steps S1011 to S1012: S1011, obtaining the external environment temperature of the vehicle and the current temperature of the engine of the vehicle, and determining the current state of the vehicle according to the external environment temperature and the current temperature; S1012, obtaining the corresponding working condition data from the state database according to the current state of the vehicle, and determining the current working condition of the vehicle according to the working condition data.

[0024] In specific implementation, the external ambient temperature of the vehicle is obtained through a temperature sensor installed on the vehicle, and the current temperature of the engine of the vehicle is collected. When the external ambient temperature is greater than 27 °C and the current temperature (water temperature) is greater than 85 °C, it means that the current state of the vehicle is a high-temperature driving state. The operating condition data corresponding to this current state is obtained from a pre-constructed state database, and the current operating condition of the vehicle is determined using this operating condition data. Among them, the current operating condition of the vehicle includes information such as the current heat generation data of the vehicle and the throttle opening degree.

[0025] It should be noted that when the external ambient temperature is lower than -10 °C and the current temperature (water temperature) of the vehicle is higher than 85 °C, it means that the current state of the vehicle is a low-temperature driving state. The operating condition data corresponding to the low-temperature driving state is obtained from a pre-constructed state database. In the low-temperature driving state, there may be a state where the throttle freezes or the coolant freezes. The current operating condition in the low-temperature driving state also includes the temperature information of the coolant.

[0026] S102, obtain the heat dissipation parameters of the intercooler of the vehicle, where the heat dissipation parameters include the temperature data of the air outlet pipe, the fin opening data, and the heat transfer coefficient of the fins; S103, determine the corresponding current wind speed based on the current vehicle speed of the vehicle, and calculate the air-cooled heat conduction data of the intercooler according to the current wind speed and the heat transfer coefficient of the fins; Further, please refer to Figure 3 , the step S103 specifically includes steps S1031 to S1032: S1031, obtain the current vehicle speed, the front-end contact area, and the air resistance coefficient of the vehicle, and calculate the current wind speed of the vehicle according to the current vehicle speed, the front-end contact area, and the air resistance coefficient; S1032, obtain the Prandtl number of air and the air density, and calculate the air-cooled heat conduction data of the intercooler according to the current wind speed, the heat transfer coefficient of the fins, the Prandtl number of air, and the air density.

[0027] In specific implementation, the heat dissipation parameters of the intercooler of the vehicle are obtained. Among them, the heat dissipation parameters include the temperature data of the air outlet pipe, the fin opening data, and the heat transfer coefficient of the fins. The corresponding current wind speed is calculated according to the current vehicle speed of the vehicle by the following formula. The calculation formula of the current wind speed is: ; In the formula, represents the data conversion coefficient, which is a constant; represents the current vehicle speed of the vehicle; represents the air density; Represents the front-end contact area of the vehicle; Represents the air resistance coefficient; It can be understood that the front-end contact area of the vehicle is the front projection area of the vehicle. When the vehicle speed is higher, the calculated wind speed is also higher. By calculating the corresponding current wind speed, the air-cooling effect of the intercooler can be quickly calculated, the air Prandtl number can be obtained, and the air-cooling heat conduction data of the intercooler can be calculated by combining it with the air density, the above-calculated current wind speed, and the heat transfer coefficient of the fins. The calculation formula for the air-cooling heat conduction data is: ; In the formula, Represents the air-cooling heat conduction data, Represents the heat transfer coefficient of the fins, Represents the air Prandtl number, Represents the specific heat capacity of the air.

[0028] It should be noted that the larger the air-cooling heat conduction data of the intercooler, the higher the air-cooling efficiency of the intercooler under the current state, and the more heat is taken away by the external air. Map the calculated air-cooling heat conduction data, the temperature data at the air outlet pipe, and the fin opening data to obtain the air-cooling performance of the vehicle in this state.

[0029] S104. Determine the corresponding heat dissipation requirement according to the current working condition, and judge whether the air-cooling heat conduction data meets the heat dissipation requirement; In specific implementation, obtain the corresponding heat dissipation requirement of the above-obtained current working condition in the requirement library. When the current state of the vehicle is a high-temperature driving state, obtain the current heat generation data of the vehicle and use it as the current working condition, and compare it with the vehicle safety standard to obtain the heat dissipation requirement of the vehicle under this current working condition in the requirement library; Furthermore, perform temperature simulation on the above-calculated air-cooling heat conduction data, and match according to the temperature simulation result and the heat dissipation requirement. If the temperature simulation result of the air-cooling heat conduction data does not meet the heat dissipation requirement within the preset time (in this embodiment, the preset time is 15 minutes), it means that the simple air-cooling effect cannot enable the vehicle to have good heat dissipation performance within the preset time.

[0030] S105. If the air-cooling heat conduction data does not meet the heat dissipation requirement, obtain the liquid-cooling heat conduction data of the intercooler, calculate the weight data of the liquid-cooling heat conduction data and the air-cooling heat conduction data according to the heat dissipation requirement, generate the corresponding adjustment control parameter according to the weight data, and use the adjustment control parameter to adjust and control the intercooler.

[0031] Furthermore, please refer to Figure 4, step S105 specifically includes steps S1051 to S1052: S1051, obtain the liquid cooling pipeline data of the intercooler, and calculate the liquid cooling flow rate of the intercooler according to the liquid cooling pipeline data; S1052, calculate the liquid cooling heat conduction data of the intercooler according to the current temperature of the engine and the liquid cooling flow rate.

[0032] In specific implementation, if the above-mentioned air cooling heat conduction data does not meet the heat dissipation requirements, count the difference in the heat dissipation amount between the air cooling heat conduction data and the heat dissipation requirements. If the difference does not exceed half of the air cooling heat conduction data, there is no need to use the liquid cooling of the intercooler. Obtain the fin pitch of the intercooler, and use the pre-constructed heat dissipation analysis model to calculate the corresponding heat dissipation coefficient according to the fin pitch and fin opening data. If the heat dissipation coefficient is lower than 150W / m 2 *K, then obtain the maximum heat dissipation coefficient corresponding to the fin pitch, and use the maximum heat dissipation coefficient to adjust the fin opening data. The following Table 1 is a partial relationship mapping table of fin opening data, fin pitch and heat dissipation coefficient: Table 1 Serial number Fin opening data (°) Fin pitch (mm) <![CDATA[Thermal dissipation coefficient (W / m 2 *K)]]> 1 20 1 151.63 2 20 1.1 147.96 3 24 1 155.96 4 24 1.1 161.71 5 28 1 165.04 6 28 1.1 179.48 When the fin pitch is 1.1mm and the fin opening data is 20°, the heat dissipation coefficient calculated by the heat dissipation analysis model is 147.96 W / m 2 *K. This heat dissipation coefficient may not meet the heat dissipation requirements under the current working conditions of the vehicle. The fin opening data can be adjusted by a motor installed on the fins of the intercooler to 28°, so that the air cooling of the intercooler meets the heat dissipation requirements. It should be noted that before adjusting the fin opening data, the pressure drop value needs to be calculated according to the adjusted fin opening data and fin pitch to ensure that the pressure drop value does not exceed 180pa.

[0033] Furthermore, if the difference in the heat dissipation amount between the air cooling heat conduction data and the heat dissipation requirements exceeds half of the air cooling heat conduction data, the liquid cooling of the intercooler needs to be adopted. Obtain the liquid cooling pipeline data of the intercooler. Among them, the liquid cooling pipeline data includes the liquid cooling pipeline flow area and the wetted perimeter of the liquid cooling pipeline. Use the preset pipeline flow calculation formula to calculate the liquid cooling pipeline data to obtain the liquid cooling flow rate of the intercooler; Specifically, calculate the liquid cooling heat conduction data of the intercooler according to the current temperature of the engine and the liquid cooling flow rate above. The calculation formula for the liquid cooling heat conduction data of the intercooler is: ; In the formula, represents the current temperature of the engine, represents the heat dissipation temperature generated by the air cooling heat conduction data, represents the liquid cooling flow rate of the intercooler, represents the specific heat capacity of the coolant in the intercooler, represents the density of the coolant in the intercooler, represents the heat dissipation conversion coefficient, which is a constant.

[0034] Perform weight value allocation on the calculated air-cooled heat conduction data and liquid-cooled heat conduction data, and vectorize the air-cooled heat conduction data and liquid-cooled heat conduction data to obtain the corresponding vector sets , and perform a linear combination on the two vector sets, adding the corresponding combination coefficients: ; In the formula, represents the air-cooled heat conduction data the air-cooled data vector obtained through vectorization processing, represents the liquid-cooled heat conduction data the liquid-cooled data vector obtained through vectorization processing, , respectively represent the combination coefficients of the air-cooled data vector and the liquid-cooled data vector; Furthermore, optimize the above linear combination result. With the goal of minimizing the deviation, construct a linear equation system based on the heat dissipation demand and the linear combination, and solve the linear equation system to obtain the optimal linear combination of the air-cooled heat conduction data and the liquid-cooled heat conduction data under this heat dissipation demand, so as to obtain the weights corresponding to the air-cooled heat conduction data and the liquid-cooled heat conduction data; generate the corresponding adjustment control parameters according to the calculated weight values, and use the adjustment control parameters to adjust and control the intercooler to achieve the heat dissipation control of the vehicle.

[0035] In summary, for the control method of the automotive intercooler in the above embodiments of the present invention, by obtaining the external environment information of the vehicle and the current temperature of the engine to determine the current working condition of the vehicle, and then enabling the heat dissipation of the intercooler to be adjusted according to the current working condition; obtaining the heat dissipation parameters of the intercooler, calculating the air-cooled heat conduction data of the intercooler according to the current wind speed and the heat dissipation parameters, comparing the air-cooled heat conduction data with the heat dissipation demand corresponding to the current working condition, obtaining the corresponding heat dissipation strategy based on the comparison result, and using the heat dissipation strategy to adjust and control the intercooler, so that the intercooler can adjust the heat dissipation strategy according to the current working condition of the vehicle, thereby reducing the energy consumption of the vehicle, improving the service life of the intercooler and the corresponding heat dissipation performance.
