DETAILED DESCRIPTION

[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings.

The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] First, the terms involved in this application are explained:

[0049] High-voltage electronic fan: High-voltage electronic fan is a key component used in vehicle cooling systems, especially in engine cooling and air conditioning systems. It controls air flow by adjusting the fan speed, thereby affecting the cooling effect. Unlike traditional mechanical fans, high-voltage electronic fans are managed by an electronic control unit (ECU), which can accurately adjust the fan speed as needed, and because they are designed to operate under high-voltage conditions, they can provide a strong cooling effect in a short time.

[0050] In view of the existing vehicle high-voltage electronic fan control technology, it is impossible to control the high-voltage electronic fan in real time under different vehicle driving conditions, resulting in poor vehicle heat dissipation effect and high energy consumption of the high-voltage electronic fan. The technical concept of this application is:

[0051] For vehicles where the air conditioning condenser in the cab, the engine radiator, and the intercooler are all cooled by high-voltage electronic fans, the minimum fan speed required for the air conditioning condenser to dissipate heat is determined based on the target temperature set for the air conditioning and the ambient temperature in the cab; the minimum fan speed required for engine heat dissipation is determined based on the temperature of the vehicle engine cooling water; and the minimum fan speed required for the optimal engine intake temperature is determined based on the engine intake temperature. The minimum of the above three fan speeds is determined as the target speed of the vehicle's high-voltage electronic fan, and the high-voltage electronic fan is controlled to run at the target speed.

[0052] 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.

[0053] Embodiment 1

Specifically, the method can be applied to the control unit of the high-voltage electronic fan of the above-mentioned vehicle, the control unit is connected to a storage unit, the control unit is communicatively connected to a signal acquisition unit, and the signal acquisition unit collects the target temperature set for the vehicle's air conditioner, the ambient temperature in the cab, the engine water temperature, and the engine intake temperature. The signal acquisition unit can obtain the above data through the vehicle's CAN bus. Figure 1 As shown, the method includes:

[0055] S101, determining a first minimum fan speed required for condenser heat dissipation according to a target temperature set for the air conditioner and an ambient temperature in the cab;

[0056] Specifically, the control unit of the high-voltage electronic fan can obtain the target temperature set by the air conditioner through the vehicle's CAN bus, and obtain the ambient temperature in the cab through a temperature sensor in the cab.

[0057] In this step, the difference between the target temperature set by the air conditioner and the ambient temperature in the cab can be calculated, and the difference can be used as the input of the PID controller, and the PID controller outputs the first minimum fan speed. The target temperature set by the air conditioner and the ambient temperature in the cab can also be input into the deep learning model, and the deep learning model outputs the first minimum fan speed.

[0058] S102, determining a second minimum fan speed required for radiator heat dissipation according to the water temperature of the engine;

[0059] Specifically, the control unit of the high-voltage electronic fan can obtain the engine water temperature through the vehicle's CAN bus. The current engine water temperature can be measured by a temperature sensor, and the control unit can determine the target water temperature of the engine cooling water according to the engine operating conditions.

[0060] In this step, the control unit of the high-voltage electronic fan can determine the second minimum fan speed according to the water temperature of the engine and the target water temperature of the engine cooling water. For example, the difference between the current water temperature of the engine and the target water temperature can be calculated, and the difference can be used as the input of the PID controller, and the PID controller outputs the second minimum fan speed. The current water temperature of the engine and the target water temperature of the engine cooling water can also be input into the deep learning model, and the deep learning model outputs the second minimum fan speed.

[0061] S103, determining a third minimum fan speed required for heat dissipation of the intercooler according to the intake air temperature of the engine;

[0062] Specifically, the control unit of the high-voltage electronic fan can obtain the engine intake temperature through the vehicle's CAN bus, and the current engine intake temperature can be measured by a temperature sensor in the engine intake duct. The target engine intake temperature can be determined by the control unit according to the engine's operating conditions.

[0063] In this step, the high-voltage electronic fan control unit can determine the third minimum fan speed according to the engine's intake temperature and the engine's target intake temperature. For example, the difference between the engine's current water temperature and the target intake temperature can be calculated, and the difference can be used as the input of the PID controller, which outputs the third minimum fan speed. The engine's current intake temperature and the engine's target intake temperature can also be input into the deep learning model, which outputs the third minimum fan speed.

[0064] S104: Determine the maximum of the first minimum fan speed, the second minimum fan speed, and the third minimum fan speed as the target speed, and control the high-voltage electronic fan to run at the target speed.

[0065] Specifically, in this step, after the control unit of the high-voltage electronic fan determines the target speed, it controls the high-voltage electronic fan to run at the target speed.

[0066] The technical effects of this embodiment are:

[0067] Since the engine radiator is used to dissipate heat from the engine cooling water, and the intercooler is used to adjust the engine intake temperature, for vehicles in which the air conditioning condenser in the cab, the engine radiator of the vehicle, and the intercooler are all cooled by high-voltage electronic fans, the minimum fan speed required by the high-voltage electronic fan is determined according to the target temperature set by the air conditioner and the ambient temperature in the cab, the engine water temperature, and the engine intake temperature, and the maximum of the three minimum fan speeds is determined as the target speed. When the high-voltage electronic fan is running at the target speed, the heat dissipation requirements of the vehicle's current real-time driving conditions can be met, and since the above three fan speeds are all minimum fan speeds, the energy consumption of the high-voltage electronic fan can be reduced. At the same time, since the maximum of the three fan speeds is used as the final fan speed, the problem of frequent fan shifting is alleviated, which is conducive to increasing the life of the fan and reducing its operating instability.

[0068] The vehicle high-voltage electronic fan control method of the present application is described in detail using a specific embodiment below.

[0069] Embodiment 2

[0070] Figure 2 Schematic diagram of the vehicle high-voltage electronic fan control method provided in the embodiment of the present application Figure 2 ,like Figure 2 As shown, the method includes:

[0071] S201, detecting the ambient temperature in the cab;

[0072] Specifically, in this step, the temperature can be measured by a temperature sensor installed in the vehicle cab.

[0073] S202, calculating a first temperature difference between the target temperature and the ambient temperature in the cab, and determining a first minimum fan speed required for heat dissipation of the air-conditioning condenser according to the first temperature difference, wherein the larger the first temperature difference, the lower the first minimum fan speed;

[0074] In this step, the first temperature difference can be obtained by subtracting the ambient temperature in the cab from the target temperature. Optionally, the first numerical interval in which the first temperature difference is located can be determined, and the fan speed corresponding to the first numerical interval can be determined as the first minimum fan speed. The larger the lower limit of the first numerical interval, the lower the corresponding fan speed. For example, the first numerical interval can be the first temperature difference > 2.5°C, 1°C < the first temperature difference ≤ 2.5°C, 0°C < the first temperature difference ≤ 1°C, -1°C < the first temperature difference ≤ 0°C, -2.5°C < the first temperature difference ≤ -1°C, and the first temperature difference < -2.5°C. When the first temperature difference is greater than 2.5°C, the first minimum fan speed may be the first speed; when 1°C is less than the first temperature difference ≤ 2.5°C, the first minimum fan speed may be the second speed; when 0°C is less than the first temperature difference ≤ 1°C, the first minimum fan speed may be the third speed; when -1°C is less than the first temperature difference ≤ 0°C, the first minimum fan speed may be the fourth speed; when -2.5°C is less than the first temperature difference ≤ -1°C, the first minimum fan speed may be the fifth speed; when the first temperature difference is less than -2.5°C, the first minimum fan speed may be the sixth speed. The first speed is 0% of the full speed of the high-voltage electronic fan, the second speed is 17% of the full speed of the high-voltage electronic fan, the third speed is 33% of the full speed of the high-voltage electronic fan, the fourth speed is 66% of the full speed of the high-voltage electronic fan, the fifth speed is 80% of the full speed of the high-voltage electronic fan, and the sixth speed is 100% of the full speed of the high-voltage electronic fan.

[0075] In practical applications, the specific division of the first numerical interval, the specific upper and lower limit values ​​of the first numerical interval, and the fan speeds corresponding to different first numerical intervals are not limited to the examples provided in this embodiment. By dividing the first numerical intervals into multiple ones, and according to the first numerical interval in which the first temperature difference is located, the first minimum fan speed can be quickly determined without complicated algorithm calculation.

[0076] Optionally, calculating a first temperature difference between the target temperature and the ambient temperature in the cab, and determining a first minimum fan speed required for heat dissipation of the air conditioner condenser according to the first temperature difference may also include:

[0077] Step 1: Obtain the air conditioning working mode information and detect the ambient temperature outside the cab;

[0078] Step 2: The deep learning model outputs the first minimum fan speed based on the first temperature difference, the air conditioning working mode information, and the outdoor ambient temperature of the cab.

[0079] Specifically, the air-conditioning mode information in step one can be air-conditioning cooling mode, heating mode, initial mode, etc. By obtaining the air-conditioning working mode information, the ambient temperature outside the cab, and the first temperature difference, a more accurate first minimum fan speed can be given through a deep learning model, thereby effectively reducing the energy consumption of the high-voltage electronic fan.

[0080] S203, determining a second numerical interval in which the engine water temperature is located, and determining the fan speed corresponding to the second numerical interval as a second minimum fan speed, wherein the larger the lower limit value of the second numerical interval is, the higher the corresponding fan speed is;

[0081] In this step, the second numerical range can be engine water temperature ≤93°C, 93°C<engine water temperature ≤95°C, 95°C<engine water temperature ≤97°C, 97°C<engine water temperature ≤100°C, 100°C<engine water temperature ≤101°C, engine water temperature>101°C.

[0082] When the engine water temperature is ≤93℃, the second minimum fan speed may be the first speed; when 93℃<engine water temperature≤95℃, the second minimum fan speed may be the second speed; when 95℃<engine water temperature≤97℃, the second minimum fan speed may be the third speed; when 97℃<engine water temperature≤100℃, the second minimum fan speed may be the fourth speed; when 100℃<engine water temperature≤101℃, the second minimum fan speed may be the fifth speed; when the engine water temperature>101℃, the second minimum fan speed is the sixth speed. The first speed is 0% high-voltage electronic fan full speed, the second speed is 17% high-voltage electronic fan full speed, the third speed is 33% high-voltage electronic fan full speed, the fourth speed is 66% high-voltage electronic fan full speed, the fifth speed is 80% high-voltage electronic fan full speed, and the sixth speed is 100% high-voltage electronic fan full speed.

[0083] In practical applications, the specific division of the second numerical interval, the specific upper and lower limit values ​​of the second numerical interval, and the fan speeds corresponding to different second numerical intervals are not limited to the examples provided in this embodiment. By dividing the second numerical intervals into multiple ones, and according to the second numerical interval in which the second temperature difference is located, the second minimum fan speed can be quickly determined without complicated algorithm calculation.

[0084] S204, determining a third minimum fan speed required for heat dissipation of the intercooler according to the engine intake air temperature;

[0085] In this step, the third numerical interval of the engine intake temperature can be determined, and the fan speed corresponding to the third numerical interval is determined as the third minimum fan speed. The larger the lower limit of the third numerical interval, the higher the corresponding fan speed. For example, the third numerical interval can be engine intake temperature ≤ 70°C, 70°C < engine intake temperature ≤ 75°C, 75°C < engine intake temperature.

[0086] Specifically, when the engine intake temperature is ≤70°C, the third minimum fan speed is the first speed; when 0°C<engine intake temperature≤75°C, the third minimum fan speed is the third speed; when 75°C<engine intake temperature, the third minimum fan speed is the sixth speed. The first speed is 0% of the high-voltage electronic fan full speed, the third speed is 33% of the high-voltage electronic fan full speed, and the sixth speed is 100% of the high-voltage electronic fan full speed.

[0087] In practical applications, the specific division of the third numerical interval, the specific upper and lower limits of the third numerical interval, and the fan speeds corresponding to different third numerical intervals are not limited to the examples provided in this embodiment. By dividing the third numerical intervals into multiple ones, and according to the third numerical interval in which the third temperature difference is located, the third minimum fan speed can be quickly determined without complicated algorithm calculation.

[0088] Optionally, this embodiment provides another method for determining the third minimum fan speed: Figure 3 A flowchart of another method for determining a third minimum fan speed provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method includes:

[0089] S301, detecting the air temperature and relative humidity of the environment outside the vehicle cab;

[0090] In this step, a temperature sensor and a humidity sensor can be used to detect the air temperature and relative humidity of the environment outside the vehicle cab.

[0091] S302, calculating the target engine intake temperature according to the air temperature and the relative humidity of the air;

[0092] In this step, the target intake air temperature corresponding to the air temperature and relative humidity of the outdoor environment of the cab can be determined by looking up a table, or the target intake air temperature can be calculated based on a thermodynamic model, which may include parameters such as engine load and speed, fuel type, etc.

[0093] S303, calculating a second temperature difference between the target intake temperature and the engine intake temperature, and calculating a target cooling amount according to the second temperature difference, the engine intake flow rate, and an intercooler efficiency parameter;

[0094] In this step, the actual intake air flow rate of the engine can be measured by the flow sensor in the engine intake duct, usually in cubic meters per second (m³ / s). The cooling power requirement can be calculated based on the engine intake air flow rate using thermodynamic formulas.

[0095] The intercooler efficiency is usually an empirical value, which indicates the cooling capacity of the intercooler under specific conditions. Specifically, the target cooling amount can be calculated according to the second temperature difference, the cooling power requirement and the intercooler efficiency parameter.

[0096] S304: Calculate a third minimum fan speed according to the second temperature difference, the target cooling amount, and the high-voltage electronic fan characteristic curve.

[0097] In this step, the high-voltage electronic fan characteristic curve can establish a mapping relationship between the fan speed, the second temperature difference, and the target cooling amount, thereby determining the third minimum fan speed.

[0098] pass Figure 3 The method shown takes into account various parameters of the engine and the temperature and humidity parameters of the vehicle's current environment, and can more accurately calculate the third minimum fan speed, effectively reducing energy consumption.
