Description

Technical Field

[0001] This application relates to the field of fan control technology, specifically to a method, device, and medium for controlling the fan speed required by an air conditioner. Background Technology

[0002] When the vehicle's air conditioning is on, the electronically controlled silicone oil clutch fan engages fully when stopped at a red light or similar conditions. This electronically controlled silicone oil clutch fan is a fan clutch assembly that utilizes the principle of viscous transmission, using viscous silicone oil as the transmission medium. The fan speed is controlled by adjusting the amount of silicone oil involved. Due to the limitations of its operating principle, when the vehicle restarts, the electronically controlled silicone oil clutch fan cannot quickly disengage, causing the fan speed to increase with the engine speed. This results in wasted fuel power and affects vehicle economy. Summary of the Invention

[0003] To address the aforementioned problems, this application proposes a method for controlling the fan speed of an air conditioner, comprising:

[0004] The actual rotational speed of the electronically controlled silicone oil clutch fan is obtained, and the vehicle state corresponding to the vehicle is determined based on the actual rotational speed; wherein, the vehicle state includes idling state and non-idling state;

[0005] Based on the vehicle status, the required air conditioning fan speed for the vehicle is determined to be either a first preset value or a second preset value; wherein the first preset value is greater than the second preset value.

[0006] When the vehicle is in an idling state, the actual speed of the electronically controlled silicone oil clutch fan is reduced to the second preset value, so that the ratio between the second preset value and the actual engine speed is less than the fan speed ratio, and the electronically controlled silicone oil clutch fan does not enter a fully engaged state.

[0007] When the vehicle transitions from the idling state to the non-idling state, the electronically controlled silicone oil clutch fan, which is not fully engaged, is disengaged from the engine.

[0008] In one implementation of this application, when the vehicle transitions from the idling state to the non-idling state, before disengaging the electronically controlled silicone oil clutch fan (which is not yet fully engaged) from the engine, the method further includes:

[0009] Determine the cumulative duration of the idling state;

[0010] The cumulative state duration is compared with the preset duration. If the cumulative state duration is greater than the preset duration, the speed of the first air conditioner fan is adjusted to obtain the corresponding second air conditioner fan speed.

[0011] In one implementation of this application, determining the vehicle state based on the actual rotational speed specifically includes:

[0012] The actual engine speed and fan speed ratio of the vehicle are obtained, and the critical speed corresponding to the state of the electronically controlled silicone oil clutch fan is determined based on the actual engine speed and the fan speed ratio.

[0013] The actual rotational speed is compared with the critical rotational speed. When the actual rotational speed is greater than the critical rotational speed, the vehicle state is determined to be idling. When the actual rotational speed is less than the critical rotational speed, the vehicle state is determined to be non-idling.

[0014] In one implementation of this application, the critical speed corresponding to the state of the electronically controlled silicone oil clutch fan is determined based on the actual engine speed and the fan speed ratio, specifically including:

[0015] The critical speed of the electronically controlled silicone oil clutch fan is determined using the following formula, based on the actual engine speed and the fan speed ratio:

[0016] v l =v e *sr-50

[0017] Among them, v l The critical speed of the state is represented by v. e sr represents the actual engine speed, and sr represents the fan speed ratio.

[0018] In one implementation of this application, the fan speed ratio represents the ratio between the fan speed of the electronically controlled silicone oil clutch fan in the fully engaged state and the engine idle speed.

[0019] In one implementation of this application, determining the first air conditioning fan speed required by the vehicle to be a first preset value or a second preset value based on the vehicle status specifically includes:

[0020] When the vehicle is in a non-idling state, the first air conditioning fan speed required for the vehicle is determined to be a first preset value.

[0021] Obtain the engine idle speed and fan speed ratio corresponding to the vehicle, and determine the second preset value using the following formula:

[0022] v m =v ei *sr-50

[0023] Among them, v m Indicates the second preset value, vei Indicates the engine idle speed;

[0024] When the vehicle is in an idling state, the second air conditioning fan speed required for the vehicle is determined to be the second preset value.

[0025] In one implementation of this application, the speed of the first air conditioner demand fan is adjusted to obtain the corresponding second air conditioner demand fan speed, specifically including:

[0026] The first air conditioning demand fan speed is adjusted from the second preset value to the first preset value, and the first preset value is used as the second air conditioning demand fan speed, so that the vehicle can maintain normal air conditioning cooling at the second air conditioning demand fan speed.

[0027] In one implementation of this application, before obtaining the actual rotational speed of the electronically controlled silicone oil clutch fan, the method further includes:

[0028] Determine whether the air conditioning switch or air conditioning pressure switch of the vehicle is in the on state;

[0029] If the air conditioning pressure switch is in the open state, the air conditioning pressure of the vehicle is obtained, and when the air conditioning pressure is at a preset value, the electronically controlled silicone oil clutch fan is controlled to rotate.

[0030] This application embodiment provides an air conditioner demand fan speed control device, the device including:

[0031] At least one processor; and,

[0032] A memory communicatively connected to the at least one processor; wherein,

[0033] The memory stores instructions executable by the at least one processor, which, when executed by the at least one processor, enable the at least one processor to:

[0034] The actual rotational speed of the electronically controlled silicone oil clutch fan is obtained, and the vehicle state corresponding to the vehicle is determined based on the actual rotational speed; wherein, the vehicle state includes idling state and non-idling state;

[0035] Based on the vehicle status, the required air conditioning fan speed for the vehicle is determined to be either a first preset value or a second preset value; wherein the first preset value is greater than the second preset value.

[0036] When the vehicle is in an idling state, the actual speed of the electronically controlled silicone oil clutch fan is reduced to the second preset value, so that the ratio between the second preset value and the actual engine speed is less than the fan speed ratio, and the electronically controlled silicone oil clutch fan does not enter a fully engaged state.

[0037] When the vehicle transitions from the idling state to the non-idling state, the electronically controlled silicone oil clutch fan, which is not fully engaged, is disengaged from the engine.

[0038] This application provides a non-volatile computer storage medium storing computer-executable instructions, wherein the computer-executable instructions are configured as follows:

[0039] The actual rotational speed of the electronically controlled silicone oil clutch fan is obtained, and the vehicle state corresponding to the vehicle is determined based on the actual rotational speed; wherein, the vehicle state includes idling state and non-idling state;

[0040] Based on the vehicle status, the required air conditioning fan speed for the vehicle is determined to be either a first preset value or a second preset value; wherein the first preset value is greater than the second preset value.

[0041] When the vehicle is in an idling state, the actual speed of the electronically controlled silicone oil clutch fan is reduced to the second preset value, so that the ratio between the second preset value and the actual engine speed is less than the fan speed ratio, and the electronically controlled silicone oil clutch fan is not in a fully engaged state; when the vehicle moves from the idling state to the non-idling state, the electronically controlled silicone oil clutch fan, which is not in a fully engaged state, is disengaged from the engine.

[0042] The air conditioning demand fan speed control method proposed in this application can bring the following beneficial effects:

[0043] After the air conditioning is turned on, the vehicle's status is assessed. When the vehicle enters idling mode, the fan speed required by the air conditioning is reduced so that the ratio of the fan speed to the actual engine speed is less than the fan speed ratio. This prevents the electronically controlled silicone oil clutch fan from entering full engagement, allowing it to disengage quickly when the vehicle restarts, avoiding power waste and improving the overall fuel economy.

[0048] 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.

[0049] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0050] like Figure 1 As shown in the embodiment of this application, an air conditioner demand fan speed control method includes:

[0051] S101: Obtain the actual speed of the electronically controlled silicone oil clutch fan, and determine the corresponding vehicle status based on the actual speed; the vehicle status includes idling status and non-idling status.

[0052] The status of the air conditioning switch or the air conditioning pressure switch determines the required fan speed. In vehicles without an air conditioning pressure switch, the electronically controlled silicone oil clutch fan rotates when the air conditioning switch is on. In vehicles with an air conditioning pressure switch, when the pressure switch is on, the electronically controlled silicone oil clutch fan needs to be monitored for air conditioning pressure. When the air conditioning pressure reaches a preset value, it controls the electronically controlled silicone oil clutch fan to rotate. The fan stops rotating when the pressure decreases.

[0053] When the air conditioning is turned on, the vehicle will enter an idling state when encountering situations such as stopping at traffic lights, coasting in neutral, or when the vehicle speed and engine speed drop to a certain level. At this time, the engine speed is typically around 600 rpm, and the air conditioning fan speed is around 700 rpm. However, upon restarting, because the air conditioning fan speed is higher, the electronically controlled silicone oil clutch fan remains fully engaged and cannot disengage from the engine, reducing fuel economy. Therefore, it is necessary to adjust the corresponding air conditioning fan speed in real time for different vehicle conditions to avoid power waste caused by the inability to disengage when restarting.

[0054] In this embodiment, the vehicle status is divided into two categories based on the engine's operating state: idling and non-idling. The vehicle status can be determined based on the actual rotational speed of the electronically controlled silicone oil clutch fan.

[0055] Specifically, the actual engine speed and fan speed ratio of the vehicle are obtained, and the critical speed corresponding to the state of the electronically controlled silicone oil clutch fan is determined based on the actual engine speed and fan speed ratio.

[0056] The critical speed of the electronically controlled silicone oil clutch fan can be determined using the following formula:

[0057] v l =v e *sr-50

[0058] Among them, v l The critical speed of the state is represented by v. e sr represents the actual engine speed, and sr represents the fan speed ratio.

[0059] In the above formula, the fan speed ratio represents the ratio between the fan speed of the electronically controlled silicone oil clutch fan in the fully engaged state and the engine idle speed. The product of the actual engine speed and the fan speed ratio is the fully engaged speed of the electronically controlled silicone oil clutch fan in the fully engaged state. When the fan set speed approaches the fully engaged speed, due to the performance of the electronically controlled silicone oil clutch itself and the influence of the PID control, the fan is very likely to enter the fully engaged state. Subtracting 50 r / min can ensure that the fan does not enter the fully engaged state.

[0060] Furthermore, once the critical speed for the state is determined, the actual fan speed is compared with the critical speed. If the actual speed is greater than the critical speed, it indicates that the fan is in full engagement, and the vehicle's state can be determined to be idling. If the actual speed is less than the critical speed, it indicates that the fan is in partial engagement, and the vehicle's state can be determined to be non-idling.

[0061] S102: Based on the vehicle status, determine the first air conditioning fan speed required by the vehicle to be a first preset value or a second preset value; wherein the first preset value is greater than the second preset value.

[0062] The required air conditioning fan speed varies depending on the vehicle's operating conditions. Typically, when the air conditioning is on, the required fan speed is a preset value, such as 700 rpm, to ensure proper cooling. It should be noted that this value is merely an example and can be set according to the actual model or application requirements; this embodiment does not limit this setting. However, once the vehicle enters idle mode, maintaining a fan speed of 700 rpm will cause the fan to be fully engaged. When the vehicle restarts, the fully engaged fan becomes uncontrolled, and its speed changes proportionally to the engine speed. Higher engine speeds result in faster fan disengagement, leading to slower fan disengagement and impacting fuel economy.

[0063] Therefore, when the vehicle is not idling, the speed of the first air conditioning demand fan should be set to the first preset value to ensure normal air conditioning cooling. When the vehicle is idling, the speed of the first air conditioning demand fan should be reduced to ensure that the electronically controlled silicone oil clutch fan can disengage quickly when the vehicle restarts. At this time, the engine idle speed and fan speed ratio are obtained, and the second preset value is determined using the following formula:

[0064] v m =v ei *sr-50

[0065] Among them, v m Indicates the second preset value, v ei This indicates the engine's idle speed.

[0066] Then, the fan speed corresponding to the vehicle's second air conditioning requirement is set to the second preset value.

[0067] S103: When the vehicle is in an idling state, the actual speed of the electronically controlled silicone oil clutch fan is reduced to a second preset value, so that the ratio between the second preset value and the actual engine speed is less than the fan speed ratio, and the electronically controlled silicone oil clutch fan does not enter a fully engaged state.

[0068] After determining the second air conditioning fan speed required by the vehicle at idle, the actual speed of the electronically controlled silicone oil clutch fan is reduced to a second preset value, such as 550 rpm. This ensures that the ratio between the second preset value and the actual engine speed is less than the fan speed ratio, thus preventing the electronically controlled silicone oil clutch fan from entering a fully engaged state and allowing for stepless speed regulation based on the second air conditioning fan speed requirement.

[0069] S104: When the vehicle transitions from idling to non-idling, the electronically controlled silicone oil clutch fan, which is not fully engaged, disengages from the engine.

[0070] When the vehicle restarts at a green light or during other starting conditions, the engine transitions from idle to non-idle. At this time, the electronically controlled silicone oil clutch fan is not fully engaged and can quickly disengage from the engine during the starting phase. Once disengaged, the corresponding air conditioning fan speed will change to the first preset value to ensure effective air conditioning cooling during normal vehicle operation.

[0071] In one embodiment, after the vehicle enters idling mode, the cumulative duration of the idling state needs to be determined, and then compared with a preset duration. If the cumulative duration exceeds the preset duration, it indicates that the vehicle is in a long idling state. Due to the long idling time, in order to meet the air conditioning cooling demand, the first air conditioning demand fan speed needs to be adjusted to obtain a corresponding second air conditioning demand fan speed. That is, the first air conditioning demand fan speed is adjusted from a second preset value to a first preset value, and the first preset value is used as the second air conditioning demand fan speed. By restoring the air conditioning demand fan speed, the air conditioning cooling demand can be met even under long idling conditions.

[0072] like Figure 2 The diagram shown illustrates the effect of an air conditioner demand fan speed control strategy. Figure 2 The upper part is a diagram illustrating the fan disengagement efficiency when the air conditioning fan speed is maintained at 700 rpm. During the vehicle restart phase, the fan speed increases synchronously with the engine speed, and it takes about 40 seconds to disengage. Figure 2 The lower part is a schematic diagram illustrating the fan disengagement efficiency after adjusting the air conditioning fan speed. Once the fan enters idle mode, its speed is reduced to 550 rpm. When the vehicle restarts, it can directly disengage from the engine, effectively reducing fuel consumption. Experimental data shows that, comparing two different strategies, considering only the starting phase (first 40 seconds), the fan power is reduced by 3.3 kW after applying the control method provided in this application. Comparing the entire test cycle (80 km, approximately 12 start-stop cycles), the fan power is reduced by 0.2 kW, approximately 0.24% of the total power, equivalent to a fuel consumption of approximately 0.1 L / 100 km. The more start-stop cycles, the higher the fuel economy.

[0073] The above are embodiments of the methods proposed in this application. Based on the same idea, some embodiments of this application also provide devices and non-volatile computer storage media corresponding to the above methods.
