[0069] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

Those skilled in the art will appreciate that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way. In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more.

[0071] It should be noted that the "at..." in the embodiment of the present application can be the instant when a certain situation occurs, or it can be a period of time after a certain situation occurs, and the embodiment of the present application does not specifically limit this. In addition, the control method of an electrically controlled silicone oil fan provided in the embodiment of the present application is only used as an example, and the control method of an electrically controlled silicone oil fan can also include more or less content.

[0072] As an advanced engine cooling system component, the electronically controlled silicone oil fan combines the reliability of traditional mechanical silicone oil fans with the intelligence of modern electronic control technology. It uses the viscosity of silicone oil that changes with temperature, and changes the viscosity of silicone oil by changing the temperature and fluidity of silicone oil and adding adjustable valves, so as to dynamically adjust the fan speed and control the fan speed. It aims to improve the cooling efficiency of the engine under different working conditions while minimizing unnecessary energy consumption. The engine cooling system is an important part of the heat dissipation of the whole vehicle. The power consumption of the electronically controlled silicone oil fan is proportional to its speed. If the power consumption of the fan can be reduced during driving, the power consumption of the whole vehicle can be reduced.

[0073] In the prior art, in order to ensure effective cooling of the engine, the electronically controlled silicone oil fan usually runs at the maximum speed, that is, the existing electronically controlled silicone oil fan control strategy tends to keep the fan running at the maximum speed in most cases to ensure that the engine is fully cooled. This approach is undoubtedly effective under extremely high temperature or high load conditions, but when the ambient temperature is low or the engine load is light, it may cause the following problems: First, the engine is overcooled, resulting in low engine water temperature, thereby increasing fuel consumption and emissions; second, it causes unnecessary waste of energy and reduces overall energy efficiency.

[0074] Therefore, the current control method of the electronically controlled silicone oil fan has the problem of energy waste.

[0075] Based on this, the embodiment of the present application proposes a control method, device, equipment, medium and product of an electric-controlled silicone oil fan, which can be used in the field of engine cooling technology, aiming to solve the above technical problems of the prior art, and is used to monitor the operating status of the engine (such as engine water temperature, engine speed and ambient temperature, etc.) in real time, and in combination with the preset algorithm logic, intelligently adjust the speed of the electric-controlled silicone oil fan, so as to minimize the energy consumption of the electric-controlled silicone oil fan while ensuring the safe operation of the engine, and improve the environmental adaptability and overall energy efficiency of the engine cooling system. It not only helps to save energy and reduce emissions, but also prolongs the service life of the engine and cooling system, and improves the economy and reliability of the vehicle.

[0076] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0077] Figure 1 A schematic diagram of a control method for an electrically controlled silicone oil fan provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0078] S101, obtaining control parameters of an electronically controlled silicone oil fan.

[0079] In an embodiment of the present application, the executor of a control method for an electronically controlled silicone oil fan may be an electronic control unit (ECU) in a vehicle. This electronic control unit may be a controller specially designed for an electronically controlled silicone oil fan, or it may be an existing engine control unit in the vehicle. No specific limitation is made here.

[0080] The control parameters include at least one of the following: ambient temperature, engine water temperature, vehicle speed, air conditioning status, retarder status, retarder braking torque, retarder water outlet temperature, engine speed, hydraulic oil temperature, accelerator pedal opening, and engine water temperature buffer status.

[0081] Specifically, in order to reasonably regulate the speed of the electronically controlled silicone oil fan, the ECU can obtain multiple control parameters of the electronically controlled silicone oil fan through various sensors, including: the ambient temperature of the engine, the temperature of the engine coolant (also called antifreeze or cooling water), the driving speed of the vehicle, the working status of the air conditioner, the working status of the retarder, the size of the retarder braking torque, the temperature of the retarder water outlet, the engine speed, the temperature of the hydraulic oil in the vehicle hydraulic system, the opening of the accelerator pedal, and the status of the engine water temperature buffer.

[0082] S102, determining a first target rotation speed of the electronically controlled silicone oil fan according to the control parameters.

[0083] Specifically, the ECU can determine the first target speed for the electronically controlled silicone oil fan to dissipate heat and cool the engine, retarder and air-conditioning compressor based on the multiple control parameters obtained.

[0084] S103: Obtain the altitude of the vehicle, and obtain a correction coefficient corresponding to the altitude.

[0085] In the embodiment of the present application, the correction coefficient is positively correlated with the altitude. At different altitudes, the atmospheric pressure is different, resulting in different air quality of the electrically controlled silicone oil fan at the same fan speed when the vehicle is located at different altitudes.

[0086] Due to the influence of the altitude (i.e., atmospheric pressure) on the air quality of the fan, in order to balance the influence of the high altitude of the vehicle use environment on the air quality of the fan, the first target speed of the electronically controlled silicone oil fan can be corrected according to the altitude of the vehicle. Specifically, a correction coefficient corresponding to the altitude can be introduced, and the first target speed of the electronically controlled silicone oil fan can be multiplied by the correction coefficient corresponding to the altitude.

[0087] In an optional implementation, the correction coefficient corresponding to the altitude is taken as follows: when the vehicle's altitude is 0 kilometers, the correction coefficient corresponding to the altitude is 1; when the vehicle's altitude is 1 kilometer, the correction coefficient corresponding to the altitude is 1.1; when the vehicle's altitude is 2 kilometers, the correction coefficient corresponding to the altitude is 1.2; when the vehicle's altitude is 3 kilometers, the correction coefficient corresponding to the altitude is 1.35.

[0088] S104 , correcting the first target speed by using a correction coefficient to obtain a second target speed, and determining a fan speed difference between the second target speed and the current fan speed.

[0089] In this embodiment, the second target speed is positively correlated with the correction coefficient and the first target speed. The first target speed is multiplied by the correction coefficient corresponding to the altitude of the vehicle to obtain the corrected first target speed, that is, the second target speed of the electrically controlled silicone oil fan. The fan speed difference between the second target speed and the current fan speed can then be determined based on the second target speed.

[0090] S105, performing proportional processing, differential processing and integral processing on the fan speed difference to obtain a target speed adjustment amount, so as to adjust the speed of the electronically controlled silicone oil fan according to the target speed adjustment amount.

[0091] Specifically, after calculating the fan speed difference between the second target speed and the current fan speed, the fan speed difference can be processed proportionally, differentially and integrally through a proportional-integral-derivative control (PID) algorithm to obtain a target speed adjustment amount for the current fan speed of the electronically controlled silicone oil fan, thereby adjusting the current fan speed of the electronically controlled silicone oil fan according to the target speed adjustment amount.

[0092] The present embodiment provides a control method for an electronically controlled silicone oil fan, the method comprising: obtaining control parameters of the electronically controlled silicone oil fan, the control parameters comprising at least one of the following: ambient temperature, engine water temperature, vehicle speed, air conditioning status, retarder status, retarder braking torque, retarder water outlet temperature, engine speed, hydraulic oil temperature, throttle pedal opening, engine water temperature buffer status; determining a first target speed of the electronically controlled silicone oil fan according to the control parameters; obtaining the altitude of the vehicle, and obtaining a correction coefficient corresponding to the altitude, the correction coefficient being positively correlated with the altitude; correcting the first target speed by the correction coefficient to obtain a second target speed, and determining a fan speed difference between the second target speed and the current fan speed, the second target speed being positively correlated with the correction coefficient and the first target speed; performing proportional processing, differential processing and integral processing on the fan speed difference to obtain a target speed adjustment amount, so as to adjust the speed of the electronically controlled silicone oil fan according to the target speed adjustment amount. The following technical effects are achieved: a first target speed of the electric-controlled silicone oil fan is determined according to the control parameters, and the first target speed is corrected by a correction coefficient to obtain a second target speed, and then the fan speed difference between the second target speed and the current fan speed is determined, and then the fan speed difference is processed proportionally, differentially and integrally to obtain a target speed adjustment amount, so that the current fan speed of the electric-controlled silicone oil fan is adjusted according to the target speed adjustment amount, thereby achieving the goal of minimizing unnecessary energy consumption of the electric-controlled silicone oil fan by intelligently adjusting the fan speed while ensuring safe operation of the engine, and at the same time improving the environmental adaptability and overall energy efficiency of the engine cooling system , which not only helps to save energy and reduce emissions, but also prolongs the service life of the engine and cooling system, and improves the economy and reliability of the vehicle; by obtaining the altitude of the vehicle and obtaining the correction coefficient corresponding to the altitude, the first target speed is corrected by the correction coefficient to obtain the second target speed, which fully considers the influence of the altitude of the vehicle use environment on the air quality of the fan, improves the accuracy of the target speed adjustment amount finally calculated, and thus improves the environmental adaptability of the vehicle cooling system; by performing proportional processing, differential processing and integral processing on the fan speed difference, the target speed adjustment amount is obtained, which improves the accuracy of regulating the current speed of the electronically controlled silicone oil fan.

[0093] Figure 2 A schematic diagram of a control method for an electrically controlled silicone oil fan provided in an embodiment of the present application Figure 2 In one possible example, Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, how to determine the first target speed of the electric-controlled silicon oil fan according to the control parameter, and how to adjust the speed of the electric-controlled silicon oil fan according to the target speed adjustment amount are described in detail. Figure 2 As shown, the method includes:

[0095] S201 is similar to S101 and will not be described in detail in this embodiment.

[0096] S202: Determine a mapping table group according to the ambient temperature, where different ambient temperatures correspond to different mapping table groups.

[0097] In an embodiment of the present application, each mapping table group includes one or more mapping tables, and different mapping tables in the same mapping table group correspond to different types of relationships between remaining control parameters and the first target speed, and the remaining control parameters include control parameters other than ambient temperature.

[0098] Specifically, after the control parameters of the electronically controlled silicone oil fan are obtained, firstly, a plurality of mapping table groups related to the first target speed may be determined according to the ambient temperature parameter among the plurality of control parameters, that is, according to the ambient temperature of the engine.

[0099] In an optional embodiment, if the ambient temperature is lower than a preset temperature threshold (such as 28 degrees Celsius), it can be determined that the vehicle is in a normal temperature environment, and the ECU can obtain multiple mapping table groups corresponding to the normal temperature environment; if the ambient temperature is greater than or equal to the preset temperature threshold, it can be determined that the vehicle is in a high temperature environment, and the ECU can obtain multiple mapping table groups corresponding to the high temperature environment.

[0100] Furthermore, multiple temperature thresholds may be set, so that multiple different temperature intervals are determined according to the multiple temperature thresholds, and multiple mapping table groups corresponding to each temperature interval are determined according to the multiple different temperature intervals.

[0101] In each temperature range, there are corresponding multiple mapping table groups, each mapping table group includes one or more mapping tables, and different mapping tables in the same mapping table group correspond to the relationship between different types of control parameters except the ambient temperature and the first target speed.

[0102] In each mapping table group corresponding to each ambient temperature, one or more of the following mapping tables may be included. For example: a first mapping table corresponding to engine water temperature and vehicle speed, the first mapping table may include a table of the correspondence between ambient temperature and fan speed, a table of the correspondence between engine water temperature and fan speed, and a table of the correspondence between vehicle speed and fan speed. In addition, the first mapping table may also be a table of the correspondence between the three control parameters of ambient temperature, engine water temperature and vehicle speed and the fan speed. There is no specific limitation here.
