Description

Technical Field

[0001] This application relates to the field of fuel heaters, and in particular to an adaptive environmental start control method and a parking heater. Background Technology

[0002] Parking heaters (or fuel heaters, etc.) provide heat by burning fuel through their burners. During burner operation, fuel viscosity increases sharply in low-temperature environments, leading to poor atomization. Additionally, the volumetric airflow rate drawn in by the fan may decrease slightly due to changes in cold air viscosity, altering the overall intake characteristics.

[0003] Therefore, in low-temperature environments, due to poor diesel atomization and low air intake, the ignition failure rate is likely to increase. Summary of the Invention

[0004] To address the existing technical problems, this application provides an adaptive environmental start-up control method and a parking heater that can improve ignition success rate.

[0005] In a first aspect, embodiments of this application provide an adaptive environment start-up control method applied to a parking heater, the parking heater including a fan and an oil pump, the method comprising: acquiring environmental data of the parking heater; the environmental data including at least one of the following: ambient temperature data, ambient humidity data, and external air pressure data; determining the corresponding fan speed and / or oil pumping frequency based on the environmental data; controlling the operation of the fan based on the fan speed, and / or controlling the operation of the oil pump based on the oil pumping frequency.

[0006] Secondly, embodiments of this application provide a parking heater, including a control module, which is used to execute the adaptive environment start-up control method described in any embodiment of this application.

[0007] In the adaptive environment start-up control method provided in the above embodiments, environmental data of the parking heater is acquired. This environmental data includes at least one of the following: ambient temperature data, ambient humidity data, and external air pressure data. Based on the environmental data, the corresponding fan speed and / or oil pumping frequency are determined. The fan operation is controlled based on the fan speed, and / or the oil pump operation is controlled based on the oil pumping frequency. Thus, by collecting environmental data, the current external environmental conditions such as temperature, humidity, and air pressure can be accurately characterized. Therefore, when external environmental conditions change, the fan speed and / or oil pumping frequency can be adjusted in a timely manner. For example, in low temperature and low air pressure conditions, the fan speed can be increased to increase the air intake, and / or the oil pumping frequency can be decreased to reduce fuel viscosity and improve atomization. This allows for flexible adjustment of ignition conditions and improves the ignition success rate under different environmental conditions.

[0008] The parking heater provided in the above embodiments belongs to the same concept as the corresponding adaptive environment start-up control method embodiments, and thus has the same technical effect as the corresponding adaptive environment start-up control method embodiments, which will not be repeated here.

[0013] In the following description, the terms "first," "second," and "third" are used merely to distinguish similar objects and do not represent a specific ordering of the objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0014] like Figure 1 As shown in the figure, this application provides an adaptive environment start-up control method applied to a parking heater, the parking heater including a fan and an oil pump, the method including: S10: Obtain environmental data of the parking heater; the environmental data includes at least one of the following: ambient temperature data, ambient humidity data, and external air pressure data.

[0015] In one embodiment, the parking heater may also be referred to as a fuel heater, etc., and is an auxiliary heater that provides heat based on fuel ignition. The operating data of the parking heater can refer to relevant operational data of the parking heater. The surface temperature of the parking heater refers to the surface temperature of the aluminum body of the parking heater, which can be obtained by a temperature sensor located on the surface of the parking heater. The exhaust gas temperature refers to the temperature of the exhaust gas generated by the parking heater and discharged through the exhaust pipe, which can be obtained by a temperature sensor located in the exhaust pipe or on its inner or outer surface.

[0016] In one embodiment, the ambient temperature data may refer to the temperature of the outside air drawn in by the parking heater, for example, it can be obtained through a temperature sensor located at the air inlet of the parking heater. The ambient humidity data may refer to the humidity of the outside air drawn in by the parking heater, for example, it can be obtained through a humidity sensor located at the air inlet of the parking heater.

[0017] In one embodiment, the external air pressure data can refer to the atmospheric pressure of the environment where the parking heater is located, such as by obtaining it through an air pressure sensor on or outside the parking heater.

[0018] In one embodiment, lower temperatures result in higher fuel viscosity and lower atomization. Higher humidity also leads to lower fuel atomization. Lower external air pressure further reduces fuel atomization. Lower external air pressure can also indicate higher altitude.

[0019] S20: Determine the corresponding fan speed based on the environmental data; And / or, S30: Determine the corresponding pumping frequency based on the environmental data.

[0020] In one embodiment, the fan is a device in the parking heater used to inject air. The higher the fan speed, the faster the air is injected, meaning a larger amount of air is injected per unit time. The oil pump is a device in the parking heater used to pump fuel such as fuel oil to the burner, etc. The higher the oil pumping frequency, the faster the fuel is pumped, meaning a larger amount of fuel is pumped per unit time.

[0021] In one embodiment, the fan speed can be determined based on ambient temperature data; for example, the lower the temperature, the higher the corresponding fan speed. The fan speed can also be determined based on ambient humidity data; for example, the higher the humidity, the higher the corresponding fan speed.

[0022] In one embodiment, the pumping frequency can be determined based on ambient temperature data and / or external air pressure data. For example, the lower the temperature, the lower the corresponding pumping frequency; the lower the air pressure, the lower the corresponding pumping frequency.

[0023] In one embodiment, determining the corresponding fan speed and / or pumping frequency based on the environmental data may refer to comparing each piece of environmental data with a corresponding preset interval to determine the interval in which the environmental data is located, and determining the corresponding fan speed based on the speed range corresponding to the interval in which the environmental data is located, and / or determining the corresponding pumping frequency based on the frequency range corresponding to the interval in which the environmental data is located.

[0024] In one embodiment, determining the corresponding fan speed and / or pumping frequency based on the environmental data may include: determining the speed range corresponding to the humidity range where the environmental humidity data is located; and determining the corresponding fan speed within the speed range based on the position of the environmental humidity data within the humidity range.

[0025] In one embodiment, determining the corresponding fan speed and / or pumping frequency based on the environmental data may include: determining the frequency range corresponding to the humidity interval where the environmental humidity data is located; and determining the corresponding pumping frequency within the frequency range based on the position of the environmental humidity data within the humidity interval.

[0026] S40: Control the operation of the fan based on the fan speed; And / or, S50: Control the operation of the oil pump based on the oil pump frequency.

[0027] In one embodiment, controlling the operation of the fan based on the fan speed can mean controlling the fan to operate at that fan speed, that is, adjusting the current fan speed to the fan speed determined based on environmental data. For example, if the current fan speed is lower than the fan speed, the current speed is increased to the fan speed.

[0028] In one embodiment, controlling the operation of the oil pump based on the pumping frequency can mean controlling the oil pump to operate at that pumping frequency, that is, adjusting the current pumping frequency of the oil pump to the pumping frequency determined based on environmental data. For example, if the current pumping frequency of the oil pump is lower than the pumping frequency, the current pumping frequency is increased to the pumping frequency.

[0029] In one embodiment, controlling the operation of the fan based on the fan speed and / or controlling the operation of the oil pump based on the oil pump frequency may include: determining the changes in the ambient temperature data within a preset time period; determining the trend and rate of change of the ambient temperature data within the preset time period based on the changes; and, in response to the trend being a downward trend and the rate of change reaching a preset threshold, correcting the fan speed and / or the oil pump frequency, and controlling the operation of the fan based on the corrected fan speed and / or controlling the operation of the oil pump based on the corrected oil pump frequency.

[0030] The preset threshold may include at least one of the following: a first threshold corresponding to adjusting the fan speed based on ambient temperature data, a second threshold corresponding to adjusting the pump oil frequency based on ambient temperature data, and a third threshold corresponding to adjusting the pump oil frequency based on external air pressure data.

[0031] In one embodiment, correcting the fan speed and / or pump oil frequency may include at least one of the following: increasing the corresponding fan speed by a first preset amount, decreasing the corresponding pump oil frequency by a second preset amount, and decreasing the corresponding pump oil frequency by a third preset amount.

[0032] In one embodiment, controlling the operation of the fan based on the fan speed may include: acquiring changes in the ambient humidity data over a preset period of time; determining the trend and rate of change of the ambient humidity data over the preset period of time based on the changes; increasing the corresponding fan speed by a fourth preset amount in response to the trend being an upward trend and the rate of change reaching a fourth threshold; and controlling the operation of the fan based on the fan speed increased by the fourth preset amount.

[0033] In one embodiment, controlling the operation of the oil pump based on the pumping frequency may include: acquiring changes in the ambient humidity data within a preset time period; determining the trend and rate of change of the ambient humidity data within the preset time period based on the changes; reducing the corresponding pumping frequency by a fifth preset amount in response to the trend being an upward trend and the rate of change reaching a fifth threshold; and controlling the operation of the oil pump based on the pumping frequency after reducing the fifth preset amount.

[0034] In this way, by collecting environmental data, the current external environment conditions such as temperature, humidity, and air pressure can be accurately characterized. As the external environmental conditions change, the fan speed and / or oil pumping frequency can be adjusted in a timely manner. For example, in low temperature and low air pressure conditions, the fan speed can be increased to increase the amount of air entering, and / or the oil pumping frequency can be reduced to decrease fuel viscosity and improve atomization. This allows for flexible adjustment of ignition conditions and improves the ignition success rate under different environmental conditions.

[0035] In some embodiments, such as Figure 2 As shown, step S20 may include: S21: Determine the rotational speed range corresponding to the temperature range where the ambient temperature data is located; S22: Based on the position of the ambient temperature data in the temperature range, determine the corresponding fan speed in the speed range.

[0036] In one embodiment, the temperature range in which the ambient temperature data is located can be determined based on multiple preset temperature ranges. For example, the preset temperature ranges may include a first temperature range (above 0°C), a second temperature range (-20°C to 0°C), and a third temperature range (below -20°C), etc. Different temperature ranges correspond to different rotational speed ranges, where the rotational speed range can be a single value or a range.

[0037] In one embodiment, the lower the temperature of the temperature range, the higher the speed range corresponding to the temperature range.

[0038] For example, when the ambient temperature data is located in the first temperature range, the corresponding speed range is 2500 rpm; When the ambient temperature data falls within the second temperature range, the corresponding engine speed range is 2625 rpm to 2875 rpm. When the ambient temperature data falls within the third temperature range, the corresponding engine speed range is 2875 rpm to 3125 rpm.

[0039] In one embodiment, determining the corresponding fan speed within the speed range based on the position of the ambient temperature data within the temperature range can refer to the numerical sorting position of the ambient temperature data within the temperature range being consistent with the numerical sorting position of the corresponding fan speed within the speed range.

[0040] The numerical sorting position refers to the arrangement position of the numerical value within a range or interval. For example, in the range of -20℃ to 0℃, the numerical sorting position of -10℃ is in the middle position.

[0041] Thus, based on the rise and fall of ambient temperature, different fan speeds can be used in different temperature ranges. Furthermore, the fan speed can be increased accordingly for lower temperature ranges, thereby enabling precise matching of fan speed with ambient temperature. In addition, the fan speed can be increased in time when the temperature drops to maintain air intake and improve ignition success rate.

[0042] In some embodiments, controlling the operation of the wind turbine based on the wind turbine speed may include: Acquire the changes in the ambient temperature data within a preset time period; Based on the changes, determine the trend and rate of change of the ambient temperature data within the preset time period; In response to the trend of change being downward and the rate of change reaching a first threshold, the corresponding fan speed is increased by a first preset amount; The operation of the fan is controlled based on the fan speed after increasing the first preset amount.

[0043] In one embodiment, the preset duration can refer to the preset duration before the current moment, such as a fixed value like 1h, 2h, or 3h. Alternatively, the preset duration can be a value adjusted based on the operating level of the parking heater and / or based on environmental data other than ambient temperature data. For example, the higher the operating level of the parking heater, the longer the preset duration can be to avoid a large difference between the air intake and the demand, which could lead to ignition failure.

[0044] In one embodiment, when the external air pressure data is lower than the preset air pressure value, the preset duration is a first duration; when the external air pressure data is greater than or equal to the preset air pressure value, the preset duration is a second duration. The second duration can be greater than the first duration. Thus, when the external air pressure is low, the temperature change may be large. In this case, the time window for evaluating the rate of temperature change is shortened to accurately grasp the speed of temperature decrease.

[0045] In one embodiment, the trend is a downward trend, which may refer to a continuous decrease within a preset time period, or the ambient temperature data at the end time within the preset time period being lower than the ambient temperature data at the start time within the preset time period.

[0046] In one embodiment, the rate of change reaching the first threshold can refer to the absolute value of the rate of change reaching the first threshold, for example, reaching the first threshold can mean being greater than or equal to the first threshold.

[0047] In one embodiment, the magnitude of the first preset amount can be positively correlated with the magnitude of the rate of change. For example, if the first rate of change is greater than the second rate of change, then the first preset amount increased when the rate of change is the first rate of change is greater than the first preset amount increased when the rate of change is the second rate of change.

[0048] In one embodiment, the operation of the fan is controlled based on the fan speed after increasing the first preset amount, that is, the fan is controlled to operate at the fan speed after increasing the first preset amount.

[0049] In this way, by judging the temperature change trend and rate of change based on the preset time, the fan speed can be corrected in time when the temperature drops rapidly, so that the fan speed can be increased by a certain value to meet the ignition requirements in low temperature environment, and the changes can be avoided if the preset time is too long.

[0050] In some embodiments, such as Figure 3 As shown, step S30, which determines the corresponding pumping frequency based on the environmental data, may include: S31: Determine the temperature range where the ambient temperature data is located, and the pressure range where the external air pressure data is located; S32: Determine the corresponding pumping frequency based on the first frequency range corresponding to the temperature range and the second frequency range corresponding to the air pressure range.

[0051] In one embodiment, the temperature range in which the ambient temperature data is located can be determined based on multiple preset temperature ranges. For example, the preset temperature ranges may include a first temperature range (above 0°C), a second temperature range (-20°C to 0°C), and a third temperature range (below -20°C). Different temperature ranges correspond to different pumping frequencies, where the pumping frequency can be a single value or a range.

[0052] In one embodiment, the pressure range where the external pressure data is located can be determined based on multiple preset pressure ranges. For example, the preset pressure ranges may include a first pressure range (above 90 kPa), a second pressure range (70 kPa to 90 kPa), and a third pressure range (below 70 kPa). Different pressure ranges correspond to different pumping frequencies, where the pumping frequency can be a single value or a range.

[0053] In one embodiment, the lower the temperature of the temperature range, the lower the corresponding first frequency range.

[0054] In one embodiment, the lower the air pressure in the air pressure range, the lower the corresponding second frequency range.

[0055] For example, when the ambient temperature data is located in the first pressure range, the corresponding frequency range is 2.0-4.9Hz; When the ambient temperature data falls within the second or third pressure range, the corresponding frequency range is 1.3-3.4 Hz, etc.

[0056] In one embodiment, determining the corresponding pumping frequency based on the first frequency range corresponding to the temperature range and the second frequency range corresponding to the air pressure range may include: determining a first frequency range within the first frequency range based on the position of the ambient temperature data within the temperature range; determining a second frequency range within the second frequency range based on the position of the external air pressure data within the air pressure range; and determining the corresponding pumping frequency based on the first frequency range and the second frequency range.

[0057] In one embodiment, determining the first frequency range based on the position of the ambient temperature data within the temperature range can refer to the numerical sorting position of the ambient temperature data within the temperature range, which is consistent with the numerical sorting position of the first frequency range within the first frequency range.

[0058] In one embodiment, the second frequency range is determined based on the position of the external air pressure data in the air pressure range. This can refer to the numerical sorting position of the external air pressure data in the air pressure range, which is consistent with the numerical sorting position of the second frequency range in the second frequency range.

[0059] In one embodiment, determining the corresponding pumping frequency based on the first frequency range and the second frequency range may include: determining the corresponding pumping frequency based on the intersection of the first frequency range and the second frequency range.

[0060] The numerical sorting position refers to the arrangement position of the numerical value within a range or interval. For example, in the range of -20℃ to 0℃, the numerical sorting position of -10℃ is in the middle position.

[0061] Thus, based on the rise and fall of ambient temperature, different pumping frequencies can be used in different temperature and pressure ranges. Furthermore, for lower temperature and pressure ranges, the corresponding pumping frequency can be reduced accordingly. This allows the pumping frequency to be precisely matched with the ambient temperature and pressure. Moreover, the pumping frequency can be reduced in time when the temperature and pressure decrease to avoid excessive pumping volume, which would further weaken the atomization and improve the ignition success rate.

[0062] In some embodiments, controlling the operation of the oil pump based on the pump oil frequency includes: Acquire the changes in the ambient temperature data within a preset time period; Based on the changes, determine the trend and rate of change of the ambient temperature data within the preset time period; In response to the changing trend being a downward trend and the rate of change reaching a second threshold, the corresponding pumping frequency is reduced by a second preset amount. The operation of the oil pump is controlled based on the oil pumping frequency after reducing the second preset amount.

[0063] In one embodiment, the preset duration can refer to the preset duration before the current moment, such as a fixed value like 1h, 2h, or 3h. Alternatively, the preset duration can be a value adjusted based on the operating level of the parking heater and / or based on environmental data other than ambient temperature data. For example, the higher the operating level of the parking heater, the longer the preset duration can be to avoid a large difference between the pumped oil volume and the demand, which could lead to ignition failure.

[0064] In one embodiment, when the external air pressure data is lower than the preset air pressure value, the preset duration is a first duration; when the external air pressure data is greater than or equal to the preset air pressure value, the preset duration is a second duration. The second duration can be greater than the first duration. Thus, when the external air pressure is low, the temperature change may be large. In this case, the time window for evaluating the rate of temperature change is shortened to accurately grasp the speed of temperature decrease.

[0065] In one embodiment, the trend is a downward trend, which may refer to a continuous decrease within a preset time period, or the ambient temperature data at the end time within the preset time period being lower than the ambient temperature data at the start time within the preset time period.

[0066] In one embodiment, the rate of change reaching the second threshold can refer to the absolute value of the rate of change reaching the second threshold, for example, reaching the second threshold can mean being greater than or equal to the second threshold.

[0067] In one embodiment, the second threshold may be equal to the first threshold, or it may not be equal to the first threshold.

[0068] In one embodiment, the magnitude of the second preset amount can be positively correlated with the magnitude of the rate of change. For example, if the first rate of change is greater than the second rate of change, then the second preset amount that decreases when the rate of change is the first rate of change is greater than the second preset amount that decreases when the rate of change is the second rate of change.

[0069] In one embodiment, the operation of the blower is controlled based on the pumping frequency after reducing the second preset amount, that is, the oil pump is controlled to operate at the pumping frequency after reducing the second preset amount.

[0070] In this way, by judging the temperature change trend and rate of change based on the preset time, the pumping frequency can be corrected in time when the temperature drops rapidly, so that the pumping frequency can be reduced to a certain value to meet the fuel atomization and ignition requirements in low temperature environment. At the same time, it can avoid the change situation being inaccurate due to the preset time being too long.

[0071] In some embodiments, controlling the operation of the oil pump based on the pump oil frequency includes: Acquire the changes in the external air pressure data within a preset time period; Based on the aforementioned changes, determine the trend and rate of change of the external air pressure data within the preset time period; In response to the trend of change being downward and the rate of change reaching a third threshold, the corresponding pumping frequency is reduced by a third preset amount. The operation of the oil pump is controlled based on the oil pumping frequency after reducing the third preset amount.

[0072] In one embodiment, the preset duration can refer to the preset duration before the current moment, such as a fixed value like 1h, 2h, or 3h. Alternatively, the preset duration can be a value adjusted based on the operating level of the parking heater and / or based on environmental data other than external air pressure data. For example, the higher the operating level of the parking heater, the longer the preset duration can be, thereby avoiding a large difference between the pumped oil volume and the demand, which could lead to ignition failure.

[0073] In one embodiment, when the ambient temperature data is lower than the preset temperature value, the preset duration is a first duration; when the ambient temperature data is greater than or equal to the preset temperature value, the preset duration is a second duration. The second duration can be longer than the first duration. Thus, when the ambient temperature is low, the temperature change may be large. In this case, the time window for assessing the rate of change of air pressure is shortened to accurately grasp the speed of air pressure drop.

[0074] In one embodiment, the trend of change is a downward trend, which may refer to a continuous decrease within a preset time period, or the external air pressure data corresponding to the end time within the preset time period is lower than the external air pressure data corresponding to the start time within the preset time period.

[0075] In one embodiment, the rate of change reaching the third threshold can refer to the absolute value of the rate of change reaching the third threshold, for example, reaching the third threshold can mean being greater than or equal to the third threshold.

[0076] In one embodiment, the magnitude of the third preset amount can be positively correlated with the magnitude of the rate of change. For example, if the first rate of change is greater than the second rate of change, then the third preset amount that decreases when the rate of change is the first rate of change is greater than the third preset amount that decreases when the rate of change is the second rate of change.

[0077] In one embodiment, the operation of the blower is controlled based on the pumping frequency after reducing the third preset amount, that is, the oil pump is controlled to operate at the pumping frequency after reducing the third preset amount.

[0078] In this way, by judging the trend and rate of change of air pressure based on the preset time, the pumping frequency can be corrected in time when the air pressure drops rapidly, so that the pumping frequency can be reduced to a certain value to meet the fuel atomization and ignition requirements under low air pressure environment. At the same time, it can avoid the preset time being too long, which would result in inaccurate changes.

[0079] In some embodiments, determining the corresponding fan speed and / or pump oil frequency based on the environmental data includes: Obtain the battery voltage data that supplies power to the parking heater; In response to the battery voltage data being greater than or equal to a preset voltage value, the corresponding fan speed and / or oil pumping frequency are determined based on the environmental data.

[0080] In one embodiment, battery voltage data can characterize the remaining battery power. When the battery voltage is detected to be higher than or equal to a preset voltage value, the corresponding fan speed and / or oil pumping frequency can be determined based on ambient temperature data and external air pressure data.

[0081] In one embodiment, the method may further include: when the battery voltage data is detected to be lower than a preset voltage value (e.g., the preset voltage value is 11V), stopping the power supply to some power supply equipment when the parking heater is started by ignition. For example, stopping the power supply to the fuel preheater.

[0082] In one embodiment, the method may further include stopping the parking heater from starting when the battery voltage is below a lower voltage limit (e.g., 9V). Additionally, a low battery voltage warning message may be output.

[0083] In this way, the dynamic adjustment process of the fan speed and oil pump frequency is only performed when the battery voltage is sufficient, avoiding the waste of performance caused by performing the above calculation process when the battery voltage is low and the ignition cannot be started.

[0084] As one possible implementation, this application provides an adaptive environment start-up control method for an adaptive environment start-up of a parking heater, which may include: Activate the parking heater and obtain the current environmental data and battery voltage data of the parking heater; the environmental data includes at least one of the ambient temperature data and external air pressure data; The parking heater is activated based on the detected environmental data, using the corresponding fan speed and / or oil pump frequency.

[0085] Option 1: Control the start-up solely by ambient temperature.

[0086] A temperature sensor is installed to detect ambient temperature data. When the parking heater is activated, if the ambient temperature is higher than or equal to a first preset temperature, the fan is controlled to start and rotate at a first speed. If the ambient temperature is lower than the first preset temperature, the fan is controlled to start and rotate at a second speed, which is greater than the first speed.

[0087] Specific plan: 1. A temperature sensor is installed on the main control board at the air inlet. When turned on, the fan draws in outside air, and the temperature sensor can identify the current ambient temperature.

[0088] 2. When the temperature sensor detects that the ambient temperature is higher than 0℃, the fan will run at the reference speed of 2500rpm; 3. When the temperature sensor detects that the ambient temperature is between -20℃ and 0℃, the fan speed will increase by 5% to 15%, i.e., it will run at 2625 rpm to 2875 rpm. 4. When the temperature sensor detects that the ambient temperature is below -20℃, the fan speed will increase by 15% to 25%, i.e., it will run at 2875 rpm to 3125 rpm. Thus, when the fuel pump pushes diesel fuel into the combustion head, increasing the fan speed and air pressure further disperses the diesel fuel entering the combustion head, thereby improving the atomization effect of diesel fuel at low temperatures. Additionally, increasing the fan speed is equivalent to increasing the air intake, mitigating the slight reduction in air intake caused by changes in the viscosity of cold air at low temperatures, thereby improving the ignition success rate at low temperatures.

[0089] Option 2: Control the start-up by using ambient temperature data and external air pressure data.

[0090] The ambient temperature control is similar to that of Scheme 1.

[0091] When the atmospheric pressure sensor detects that the external air pressure is lower than the preset air pressure value, the oil pumping frequency is controlled to a first preset frequency, which is lower than the normal oil pumping frequency of the parking heater.

[0092] Option 3: Control the start-up process using battery voltage data.

[0093] When the battery voltage is detected to be higher than or equal to the preset voltage value, the parking heater is activated by controlling the corresponding fan speed and / or oil pump frequency based on ambient temperature data and external air pressure data.

[0094] When the battery voltage is lower than the first preset voltage value (e.g., 9V), a low battery voltage warning will be displayed, and the parking heater will be stopped from starting.

[0095] When the battery voltage is detected to be lower than the second preset voltage value (e.g., 11V), power supply to certain power supply devices (e.g., power supply to the fuel preheater) is stopped at the moment of ignition start.

[0096] This application also provides a parking heater, including a control module, which is used to execute the adaptive environment start-up control method described in any one or more embodiments of this application.

[0097] This application also provides a vehicle, including a parking heater and a control module connected to the parking heater, the control module being used to execute the adaptive environment start control method described in any one or more embodiments of this application.

[0098] In one embodiment, the parking heater may also include a temperature sensor connected to the control module. The temperature sensor may be located at the air inlet of the parking heater, and the control module can obtain the temperature of the intake air as ambient temperature data through the temperature sensor.

[0099] In the above embodiments, implementation can be achieved entirely or partially through software, hardware, firmware, or any combination thereof. When implemented using software, it can be implemented entirely or partially in the form of a computer program product. The computer program product includes one or more computer instructions.
