Description

Technical Field

[0001] This application relates to the field of vehicle cooling, specifically to a vehicle cooling system, method, equipment, and medium. Background Technology

[0002] In the prior art, the cooling system of a gasoline vehicle typically uses coolant to cool the engine and the hydraulic retarder installed at the rear of the transmission. Specifically, the existing cooling circuit includes a first cooling circuit in which the coolant flows to the engine, the main radiator, and the engine; a second cooling circuit in which the coolant flows to the hydraulic retarder, the auxiliary radiator, and the hydraulic retarder; and a third cooling circuit in which the coolant flows to the engine, the hydraulic retarder, the auxiliary radiator, and the engine.

[0003] While the three types of circuits mentioned above can meet the cooling needs of ordinary vehicles, for transport vehicles that are often used in special scenarios (such as slopes), especially large-volume transport vehicles (such as mining trucks), there is often an excessive cooling demand for specific components under different operating conditions. This results in the existing cooling circuits being unable to cool the modules to be cooled to the ideal temperature range, or even if cooling can be achieved by increasing the power of the radiator, it will lead to a waste of radiator energy.

[0011] In one example, generating multiple cooling schemes based on the temperature difference to be adjusted and the vehicle operating conditions specifically includes: concatenating the temperature difference to be adjusted, the vehicle load value, and the corresponding values ​​of the vehicle driving slope into a feature matrix; using the feature matrix as coordinates to determine the feature points corresponding to the feature matrix in a preset coordinate system; determining the coordinate distance between the feature points and each preset standard cooling scheme in the preset coordinate system; and selecting multiple standard cooling schemes based on the coordinate distances as the cooling schemes corresponding to the temperature difference to be adjusted and the vehicle operating conditions, wherein the number of standard cooling schemes is a preset quantity.

[0012] In one example, determining the expected cooling values ​​corresponding to the various cooling schemes specifically includes: determining the cooling circuit, the opening degree of the valve assembly, the first power of the main radiator module, the second power of the auxiliary radiator module, and the third power of the pressurization assembly in the cooling scheme; determining the first temperature to be adjusted corresponding to the engine module and the second temperature to be adjusted corresponding to the liquid buffer module; and determining the expected cooling value corresponding to the cooling scheme using the following formula:

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] Figure 1 This is a schematic diagram of a vehicle cooling system provided for one or more embodiments of this specification. Figure 1 As can be seen, the vehicle cooling system includes a main radiator module, an auxiliary radiator module, an engine module, a hydraulic retarder module, a control module, coolant pipes, and valve assemblies. The coolant pipes connect the main radiator module, auxiliary radiator module, engine module, and hydraulic retarder module. Coolant is contained within the coolant pipes, and the main and auxiliary radiator modules cool the coolant flowing through the engine and hydraulic retarder modules. During cooling of the engine and hydraulic retarder modules, heat exchange occurs between the coolant inside the coolant pipes and the engine and hydraulic retarder modules, thereby reducing their temperatures. After the coolant heats up, the main and auxiliary radiator modules provide air cooling to the coolant pipes, carrying away heat from the coolant and lowering its temperature, thus enabling recycling. Valve assemblies are located within the coolant pipes, and their opening and closing divides the coolant pipes into multiple cooling circuits. The control module is used to acquire the vehicle operating conditions of the target vehicle, as well as the current temperature information of the engine module and / or hydraulic buffer module, and control the opening and closing of the valve assembly and the power of the main radiator module and the auxiliary radiator module according to the vehicle operating conditions and the current temperature information.

[0032] Specifically, such as Figure 2As shown, the cooling circuit includes a first cooling circuit with coolant flowing through the engine module, main radiator module, and engine module; a second cooling circuit with coolant flowing through the liquid coolant buffer module, auxiliary radiator module, and liquid coolant buffer module; a third cooling circuit with coolant flowing through the engine module, liquid coolant buffer module, auxiliary radiator module, and engine module; a fourth cooling circuit with coolant flowing through the engine module, liquid coolant buffer module, main radiator module, and engine module; a fifth cooling circuit with coolant flowing through the engine module, auxiliary radiator module, liquid coolant buffer module, auxiliary radiator module, and engine module; and a sixth cooling circuit with coolant passing through the engine module, auxiliary radiator module, liquid coolant buffer module, main radiator module, and engine module. The first cooling circuit cools the coolant flowing through the engine module solely for the main radiator module, thus circulating the coolant between the main radiator module and the engine. The second cooling circuit cools the coolant flowing through the liquid coolant buffer module solely for the auxiliary radiator module, thus circulating the coolant between the auxiliary radiator module and the liquid coolant buffer module. For the third and fourth cooling circuits, under normal operating conditions, the engine's operating temperature is lower than that of the coolant retarder. Therefore, the coolant used to cool the engine can continue to be used in the coolant retarder. After cooling the retarder, it enters the main radiator module or the auxiliary radiator module, and finally, the low-temperature liquid returns to the engine. For the fifth and sixth cooling circuits, when the coolant retarder module has a high cooling demand, it is desirable for the coolant entering the retarder module to be at a lower temperature. This can be achieved by using the auxiliary radiator module to cool the coolant before it enters the retarder module, thereby lowering the coolant temperature in advance and improving cooling efficiency.

[0033] In one embodiment, to accelerate the flow rate of the coolant, the cooling system can also be equipped with a pressurization component for pressurizing the coolant in the coolant pipes. In this case, the control module also needs to acquire the coolant flow rate information in the target cooling circuit and, based on the vehicle operating conditions, flow rate information, and current temperature information, control the opening and closing of the valve assembly, the power of the pressurization component, and the power of the main radiator module and the auxiliary radiator module, thereby selecting the most suitable coolant flow rate and reducing the cooling time and energy consumption. It should be noted that in the prior art, most engines have a built-in pump function for pressurizing the cooling system, while the pressurization component in this application can be additionally installed in each cooling circuit, including at least a first pressurization component between the engine module and the main radiator module, a second pressurization component between the liquid buffer module and the auxiliary radiator module, and a third pressurization component between the engine module and the liquid buffer module.

[0034] Figure 3This document presents a flowchart illustrating a method for cooling an oil tanker, provided in one or more embodiments. The process can be executed by a control module within the cooling system. Certain input parameters or intermediate results within the process can be manually adjusted to improve accuracy. Specifically, in a test environment, operators can adjust preset weights and values ​​corresponding to the actual opening degrees of different valve components to ensure that the adjustment time and effect meet test expectations. The analysis method involved in the embodiments of this application can be implemented using a control module or a server; this application does not impose any special limitations on this. For ease of understanding and description, the following embodiments will be described in detail using a server as an example. It should be noted that the server can be a single device or a system composed of multiple devices, i.e., a distributed server; this application does not impose any specific limitations on this.

[0035] like Figure 3 As shown in the figure, this application provides a method for cooling an oil tanker, including:

[0036] S301: Obtain the vehicle operating conditions of the target vehicle.

[0037] The target vehicle here refers to the vehicle where the cooling system is located, and the vehicle operating condition refers to the working state of the vehicle. Specifically, the vehicle operating condition includes at least one of the following: unloaded uphill state, unloaded downhill state, loaded uphill state, loaded downhill state, unloaded flat road state, and loaded flat road state.

[0038] In one embodiment, when obtaining vehicle operating conditions, it is necessary to obtain the vehicle's load value and driving gradient. The vehicle load value can be measured in real time using an on-board weighing system, and the driving gradient can be measured using a gradient sensor. When the vehicle load value is higher than a certain preset threshold, the vehicle is considered to be loaded; when the vehicle load value is lower than a certain preset threshold, the vehicle is considered to be unloaded. When the vehicle gradient is higher than a certain preset threshold, the vehicle is considered to be going uphill; when the vehicle gradient is lower than a certain preset threshold, the vehicle is considered to be going downhill.

[0039] S302: Obtain the current temperature information of the engine module and / or the liquid buffer module.

[0040] When acquiring current temperature information, if only the engine module needs cooling, then only the current temperature information corresponding to the engine module needs to be acquired. Generally, however, both the engine module and the hydraulic retarder module need to be cooled simultaneously, requiring the acquisition of the current temperature information for both modules. Temperature acquisition can be achieved using temperature testing equipment connected to both the engine module and the hydraulic retarder module. After acquiring the temperature, the module to be cooled can be determined based on the current temperature information.

[0041] S303: Based on the vehicle operating conditions and the current temperature information, control the opening and closing of the valve assembly, the power of the pressurization assembly, and the power of the main radiator module and the auxiliary radiator module.

[0042] Once the vehicle's operating conditions and the module to be cooled are determined, the opening and closing of each component and its power can be controlled based on the current temperature information to select a suitable cooling solution for the module. It is understandable that different vehicle operating conditions correspond to different cooling requirements, leading to different selectable cooling circuits. Therefore, it is necessary to modify the current cooling circuit by controlling the valve assembly. Simultaneously, the flow rate of the coolant can be controlled by adjusting the opening degree of the valve assembly. Different coolant flow rates result in different amounts of heat being removed from the module to be cooled, thus leading to different energy consumption required for cooling the coolant.

[0043] In one embodiment, when determining the power of the valve assembly's opening and closing pressurization components, the main radiator module, and the auxiliary radiator module, it is first necessary to determine the ideal input temperature of the module to be cooled based on the vehicle's operating conditions. For example, when the vehicle is carrying a load uphill, the engine power is higher, and the cooling demand is greater, while when carrying a load downhill, the engine power is lower, but the coolant module has a greater cooling demand. Therefore, the ideal input temperature is different for different vehicle operating conditions; here, the ideal input temperature refers to the temperature at which the coolant enters the module. Then, based on the current temperature information of the coolant, the module to be cooled, and the ideal input temperature, it is necessary to determine the temperature difference to be adjusted. Here, the temperature difference to be adjusted refers to the temperature difference of the coolant. After determining the temperature difference to be adjusted, multiple cooling schemes can be generated based on the temperature difference to be adjusted and the vehicle's operating conditions. In different cooling schemes, the cooling circuits are different, the opening degree of the valve assembly is different, the power of the pressurization components is different, and the power of the main radiator module and the auxiliary radiator module is different. Then, the expected cooling values ​​corresponding to each of the multiple cooling schemes can be determined. Here, the expected cooling values ​​are proportional to the cooling efficiency and energy utilization efficiency of the cooling scheme. Finally, based on the expected cooling value, the target cooling scheme can be determined from multiple cooling schemes, and the opening and closing of the valve assembly, the power of the pressurization assembly, the power of the main radiator module and the auxiliary radiator module can be controlled according to the target cooling scheme.

[0044] In generating a cooling scheme, the values ​​corresponding to the temperature difference to be adjusted, the vehicle load value, and the vehicle driving slope can be concatenated into a feature matrix. This feature matrix is ​​a three-dimensional matrix. Then, the feature matrix can be used as coordinates to determine the feature points corresponding to the feature matrix in a preset coordinate system. This preset coordinate system is a three-dimensional coordinate system with multiple preset standard cooling schemes. Its format is as follows: when the temperature difference to be adjusted is a℃, the vehicle load value is b kg, and the vehicle driving slope is c°, the cooling scheme is: valve assembly opening combination d, the first power corresponding to the main radiator module is e kW·h, the second power corresponding to the auxiliary radiator module is f kW·h, and the third power corresponding to the pressurization component is g kW·h. It should be noted that the valve assembly contains multiple valves; the opening and closing of different valves can change the cooling circuit, and the opened valves can also be partially opened, thereby controlling the flow rate of the coolant passing through the valves. Each cooling scheme has different initial conditions. Therefore, the coordinate distance between the feature point and each preset standard cooling scheme can be determined in a preset coordinate system. Then, based on the coordinate distance, multiple standard cooling schemes are selected as the cooling schemes corresponding to the temperature difference to be adjusted and the vehicle operating conditions. The number of standard cooling schemes selected here can be set in advance by the staff. Then, based on the expected cooling values ​​corresponding to these cooling schemes, the most suitable target cooling scheme can be selected.

[0045] In one embodiment, when determining the expected cooling value for different cooling schemes, it is first necessary to determine the cooling circuit, the opening degree of the valve assembly, the first power of the main radiator module, the second power of the auxiliary radiator module, and the third power of the pressurization assembly in the cooling scheme; determine the first temperature to be adjusted corresponding to the engine module, and the second temperature to be adjusted corresponding to the liquid buffer module. Then, the expected cooling value corresponding to the cooling scheme can be determined using the following formula:

[0046]

[0047]

[0048]

[0049] in, This represents the expected cooling value corresponding to the cooling solution. This represents the first expected cooling value for the engine module. This represents the second expected cooling value corresponding to the liquid buffer module; , , , , , To preset weights, , The adjustment times for the engine module and the liquid buffer module corresponding to the cooling scheme are as follows: This refers to the degree of opening of the valve assembly in the cooling circuit where the engine module is located. This refers to the degree of opening of the valve assembly in the cooling circuit where the liquid buffer module is located. The third power corresponding to the pressurization component, The degree of valve assembly opening per unit time is The third power of the pressurization component is Coolant flow rate at that time; The first power corresponding to the main heatsink module This is the second power corresponding to the secondary heat sink module; , These are preset constants; their constraint functions are:

[0053] in, The actual adjustment time corresponding to the cooling scheme, specifically, Pick and The larger value between Reserve adjustment time for the temperature to be adjusted; , , , The heat exchange coefficient, When the first power corresponding to the main heat sink module and the auxiliary heat sink module is And the heat exchange coefficient is The corresponding heat exchange rate. Here, we use... This representation does not only indicate that the main and auxiliary heat sink modules have the same heat exchange capacity under the same power and heat exchange coefficient. It also means that when the main and auxiliary heat sink modules have different heat exchange capacities under the same power and heat exchange coefficient, this can be expressed as... Represents the heat exchange capacity and power of the main heat sink module Heat exchange coefficient The relationship between them, using Represents the heat exchange capacity and power of the secondary heat sink module Heat exchange coefficient The relationship between them; This is the first temperature to be adjusted for the engine module. This is the second temperature to be adjusted corresponding to the liquid buffer module; To reduce the temperature of the module to be cooled The heat lost due to temperature change; The corresponding pressurization power thresholds for different valve opening degrees. The initial amplitude is set. Once the third power exceeds the pressurization power threshold, the coolant flow rate will remain at its maximum and will not increase further.
