Description

Technical Field

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

[0002] With the rapid development of science and technology and the improvement of people's living standards, cars have become an indispensable part of people's lives and travel. Due to the popularity of cars, various high-power equipment have begun to appear on vehicles, which requires the power of car engines to be further improved.

[0003] As one of the supporting parts of turbocharging, the intercooler plays a major role in reducing the temperature of the high-temperature air after turbocharging, thereby reducing the heat load of the engine, increasing the intake volume, and thus increasing the power of the engine.

[0004] Currently, the intercooler of a vehicle is usually designed by simulating or calculating the design parameters of the intercooler according to the corresponding model before the vehicle leaves the factory, and the intercooler is directly manufactured according to the design parameters, and then the prepared intercooler is used in the corresponding vehicle. However, the intercooler is designed before leaving the factory without fully considering the status of the vehicle. Instead, the heat load is reduced according to the parameters at the factory, resulting in an increase in vehicle energy consumption. At the same time, it also makes it impossible for the intercooler to implement a reasonable heat dissipation strategy allocation during the operation of the vehicle; moreover, the heat load reduction treatment according to the parameters at the factory will cause the intercooler to be in a high-load state continuously. As the use time increases, the heat dissipation effect of the turbocharger will not reach the state at the factory, thereby affecting the performance of the vehicle. Summary of the Invention

[0054] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0055] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this 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. Example 1

[0057] See also Figure 1 , which shows a control method for an automobile intercooler in a first embodiment of the present invention, and specifically includes steps S101 to S105:

[0058] S101, obtaining external environment information of a vehicle and a current temperature of an engine, and determining a current operating condition of the vehicle based on the external environment information and the current temperature of the engine;

[0059] For further information, see Figure 2 , the step S101 specifically includes steps S1011 to S1012:

[0060] S1011, obtaining an external ambient temperature of the vehicle and a current temperature of an engine of the vehicle, and determining a current state of the vehicle according to the external ambient temperature and the current temperature;

[0061] S1012: Acquire corresponding operating condition data from a status database according to the current status of the vehicle, and determine the current operating condition of the vehicle according to the operating condition data.

[0062] During specific implementation, the vehicle's external ambient temperature is obtained through a temperature sensor installed on the vehicle, and the current temperature of the vehicle's engine is collected. If the external ambient temperature is greater than 27°C and the current temperature (water temperature) is greater than 85°C, it means that the vehicle is currently in a high-temperature driving state. The operating condition data corresponding to the current state is obtained from a pre-built state database, and the current operating condition of the vehicle is determined using the operating condition data, wherein the vehicle's current operating condition includes the vehicle's current heating data and information such as throttle opening.

[0063] It should be noted that if 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 the pre-built state database. In the low-temperature driving state, the throttle may be frozen or the coolant may be frozen. The current operating condition in the low-temperature driving state also includes the coolant temperature information.

[0064] S102, obtaining heat dissipation parameters of the intercooler of the vehicle, wherein the heat dissipation parameters include temperature data of an air outlet, fin opening data, and heat transfer coefficient of the fin;

[0065] S103, determining a corresponding current wind speed based on the current speed of the vehicle, and calculating air-cooled heat conduction data of the intercooler according to the current wind speed and the heat transfer coefficient of the fin;

[0066] For further information, see Figure 3 , the step S103 specifically includes steps S1031 to S1032:

[0067] S1031, obtaining a current vehicle speed, a front contact area, and an air resistance coefficient of the vehicle, and calculating a current wind speed of the vehicle based on the current vehicle speed, the front contact area, and the air resistance coefficient;

[0068] S1032: Obtain an air Prandtl number and an air density, and calculate air-cooled heat conduction data of the intercooler according to the current wind speed, the heat transfer coefficient of the fin, the air Prandtl number, and the air density.

[0069] In a specific implementation, the heat dissipation parameters of the vehicle's intercooler are obtained, wherein the heat dissipation parameters include the temperature data of the air outlet, the fin opening data, and the heat transfer coefficient of the fin. The current wind speed corresponding to the current speed of the vehicle is calculated according to the following formula. The calculation formula for the current wind speed is:

[0070] ;

[0071] Where, Represents the data conversion coefficient, which is a constant; Indicates the current speed of the vehicle; Indicates the air density; Indicates the front contact area of ​​the vehicle; represents the air resistance coefficient;

[0072] It can be understood that the front 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 cooling effect of the intercooler can be quickly calculated to obtain the air Prandtl number. , and compare it with the air density The air-cooled heat transfer data of the intercooler is calculated using the current wind speed and the heat transfer coefficient of the fins. The calculation formula for the air-cooled heat transfer data is:

[0073] ;

[0074] Where, Indicates air-cooled thermal conductivity data, represents the heat transfer coefficient of the fin, represents the air Prandtl number, represents the specific heat capacity of air.

[0075] It should be noted that the larger the intercooler's air-cooling heat conduction data, the higher the intercooler's air-cooling efficiency in the current state, and the greater the heat carried away by the external air. The calculated air-cooling heat conduction data is mapped with the outlet pipe temperature data and fin opening data to obtain the air-cooling performance under the vehicle's state.

[0076] S104, determining a corresponding heat dissipation requirement according to the current working condition, and judging whether the air-cooling thermal conductivity data meets the heat dissipation requirement;

[0077] In specific implementation, the current operating condition obtained above is retrieved from the demand database to obtain the corresponding heat dissipation demand. When the current state of the vehicle is a high-temperature driving state, the current heating data of the vehicle is obtained and used as the current operating condition. This data is compared with the vehicle safety standard to obtain the heat dissipation demand of the vehicle under the current operating condition from the demand database.

[0078] Furthermore, the calculated air-cooling thermal conductivity data is subjected to temperature simulation, and the temperature simulation result is matched with the heat dissipation requirement. If the temperature simulation result of the air-cooling thermal conductivity 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 air cooling effect alone cannot enable the vehicle to have good heat dissipation performance within the preset time.

[0079] S105, if the air-cooled thermal conductivity data does not meet the heat dissipation requirement, obtain the liquid-cooled thermal conductivity data of the intercooler, and calculate the weight data of the liquid-cooled thermal conductivity data and the air-cooled thermal conductivity data according to the heat dissipation requirement, generate corresponding adjustment control parameters according to the weight data, and use the adjustment control parameters to adjust and control the intercooler.

[0080] For further information, see Figure 4 , the step S105 specifically includes steps S1051~S1052:

[0081] S1051, obtaining liquid cooling pipeline data of the intercooler, and calculating the liquid cooling flow rate of the intercooler based on the liquid cooling pipeline data;

[0082] 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.

[0083] In specific implementation, if the above-mentioned air-cooled heat conduction data does not meet the heat dissipation requirements, the difference between the air-cooled heat conduction data and the heat dissipation in the heat dissipation requirements is calculated. If the difference does not exceed half of the air-cooled heat conduction data, there is no need to use liquid cooling of the intercooler. The fin spacing of the intercooler is obtained, and the corresponding heat transfer coefficient is calculated based on the fin spacing and fin opening data using the pre-built heat dissipation analysis model. If the heat transfer coefficient is lower than 150W / m 2 *K, then the maximum heat transfer coefficient corresponding to the fin spacing is obtained, and the fin opening data is adjusted using the maximum heat transfer coefficient. The following Table 1 is a partial relationship mapping table of fin opening data, fin spacing and heat transfer coefficient:

[0084] Table 1

[0085]

[0086] When the fin spacing is 1.1 mm and the fin opening is 20°, the heat transfer coefficient calculated by the heat dissipation analysis model is 147.96 W / m 2 *K, this heat transfer coefficient may not meet the heat dissipation requirements of the vehicle under the current operating conditions. The fin opening data can be adjusted to 28° through the motor installed on the intercooler fins, so that the air-cooled heat dissipation of the intercooler can meet the heat dissipation requirements. It should be noted that before adjusting the fin opening data, it is necessary to calculate the pressure drop value based on the adjusted fin opening data and fin spacing to ensure that the pressure drop value does not exceed 180pa.

[0087] Furthermore, if the difference between the statistical air-cooling heat conduction data and the heat dissipation required exceeds half of the air-cooling heat conduction data, liquid cooling of the intercooler is required. The intercooler liquid cooling pipeline data is obtained, where the liquid cooling pipeline data includes the liquid cooling pipeline flow area and the liquid cooling pipeline wetted perimeter. The liquid cooling pipeline data is calculated using a preset pipeline flow calculation formula to obtain the intercooler liquid cooling flow rate.

[0088] Specifically, the liquid cooling heat conduction data of the intercooler is calculated based on the current temperature and liquid cooling flow of the engine. The calculation formula of the liquid cooling heat conduction data of the intercooler is:

[0089] ;

[0090] Where, Indicates the current temperature of the engine, Indicates the heat dissipation temperature generated by air-cooled thermal conductivity data. Indicates the liquid cooling flow of the intercooler, Indicates the specific heat capacity of the coolant in the intercooler, Indicates the density of the coolant in the intercooler, Represents the heat dissipation conversion coefficient, which is a constant.

[0091] The calculated air-cooled thermal conductivity data and liquid-cooled thermal conductivity data are weighted and vectorized to obtain the corresponding vector set. , and linearly combine the two vector sets and add the corresponding combination coefficients:

[0092] ;

[0093] Where, Indicates air-cooled thermal conductivity data The air-cooling data vector obtained after vectorization processing is: Indicates liquid cooling thermal conductivity data The liquid cooling data vector obtained after vectorization processing, 、 Represent the combination coefficients of the air-cooled data vector and the liquid-cooled data vector respectively;

[0094] Furthermore, the above-mentioned linear combination results are optimized with the goal of minimizing the deviation. A linear equation system is constructed based on the heat dissipation demand and the linear combination, and the linear equation system is solved to obtain the optimal linear combination of the air-cooled thermal conductivity data and the liquid-cooled thermal conductivity data under the heat dissipation demand, so as to obtain the weights corresponding to the air-cooled thermal conductivity data and the liquid-cooled thermal conductivity data; corresponding adjustment control parameters are generated according to the calculated weight values, and the adjustment control parameters are used to adjust and control the intercooler to achieve heat dissipation control of the vehicle.

[0095] In summary, the control method of the automobile intercooler in the above embodiment of the present invention determines the current operating condition of the vehicle by obtaining the external environment information of the vehicle and the current temperature of the engine, so that the heat dissipation of the intercooler can be adjusted according to the current operating condition; the heat dissipation parameters of the intercooler are obtained, and the air-cooled thermal conductivity data of the intercooler is calculated according to the current wind speed and the heat dissipation parameters, the air-cooled thermal conductivity data is compared according to the heat dissipation requirements corresponding to the current operating condition, and the corresponding heat dissipation strategy is obtained based on the comparison result. The heat dissipation strategy is used to regulate and control the intercooler, so that the heat dissipation strategy of the intercooler can be adjusted according to the current operating condition of the vehicle, thereby reducing the energy consumption of the vehicle and improving the service life of the intercooler and the corresponding heat dissipation performance.
