[0035] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] In the description of the present invention, "module" and "processor" may include hardware, software or a combination of the two. A module may include hardware circuits, various suitable sensors, communication ports, and memories, and may also include software parts, such as program codes, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, a digital signal processor or any other suitable processor. The processor has data and / or signal processing functions. The processor may be implemented in software, hardware or a combination of the two.

[0037] See attached Figure 2 , Figure 2 FIG. 1 is a flow chart showing the main steps of a method for controlling the fan start-up of a parking air conditioner according to an embodiment of the present invention. Figure 2 As shown, the fan start-up control method of the parking air conditioner in the embodiment of the present invention mainly includes the following steps S101 to S107.

[0038] Step S101: Divide the preset temperature range into a plurality of continuous sub-temperature ranges in descending order of temperature values, each sub-temperature range corresponding to a different first proportionality coefficient k 1 and the second proportionality factor k 2 , k 1 and k 2 are positively correlated with the maximum value of the sub-temperature range (the larger the maximum value of the sub-temperature range, the higher the k 1 and k 2 The larger the k 1 and k 2 The smaller the k 1 ≤1, k 2 <1.

[0039] Those skilled in the art can flexibly set the specific range of the preset temperature range according to actual needs, such as 16° C. to 30° C., and the embodiment of the present invention does not impose any specific limitation on this.

[0040] In one implementation of the present invention, the second proportionality coefficient k corresponding to the same sub-temperature range is 2 Less than the first proportionality coefficient k 1 , and at the same time, the first proportional coefficient k corresponding to the first sub-temperature range in multiple continuous sub-temperature ranges 1 =1, the first proportionality coefficient k corresponding to the non-first sub-temperature range in multiple consecutive sub-temperature ranges 1 <1. For example, the sub-temperature ranges include [20, 30°C) and [16, 20°C), and the first proportionality coefficient k corresponding to [20, 30°C) is 1 =1, the first proportionality coefficient k corresponding to [16,20℃) 1 =0.8. In addition, in this embodiment, the first proportionality coefficient k corresponding to the current sub-temperature range in the plurality of continuous sub-temperature ranges is 1 Less than the second proportionality coefficient k corresponding to the previous sub-temperature range 2 For example, when [20,30℃) corresponds to the first proportionality coefficient k 1 =1, the second proportionality coefficient k 2 =0.9, the first proportionality coefficient k corresponding to [16,20℃) 1 =0.8, the second proportionality coefficient k 2=0.7.

[0041] Step S102: when the parking air conditioner is started, the sub-temperature range into which the interior temperature of the vehicle where the parking air conditioner is located falls is used as the target temperature range.

[0042] For example, the sub-temperature ranges include [16, 20°C) and [20, 30°C). If the temperature inside the vehicle is 25°C, it can be determined that the target temperature range is [20, 30°C).

[0043] Step S103: Detect whether the duration of the vehicle interior temperature falling within the target temperature range reaches a first duration; if it reaches the first duration, it indicates that the vehicle interior temperature is high and lasts for a long time, requiring a larger cooling capacity, and then go to step S107; if it does not reach the first duration, go to step S104.

[0044] Step S104: Determine whether the outdoor temperature of the vehicle is continuously greater than or equal to the minimum value of the target temperature range within the second time period; if it is greater than or equal to the minimum value of the target temperature range, it indicates that the temperature inside the vehicle is high and the temperature outside the vehicle is also high, and a larger cooling capacity is also required. At this time, you can go to step S105; if it is less than the minimum value of the target temperature range, it indicates that the temperature inside the vehicle is low and the temperature outside the vehicle is also low, and a smaller cooling capacity is required. At this time, you can go to step S106.

[0045] Step S105: Control the fan to start according to a preset normal acceleration.

[0046] Step S106: The second proportionality coefficient k corresponding to the target temperature range is 2 The product of the preset normal acceleration is used as the new speed, and the fan is controlled to start according to the new acceleration.

[0047] In step S106, since k 2 <1, using k 2 The new acceleration obtained is less than the preset normal acceleration. In the process of controlling the fan to start according to the new acceleration, the fan current generated during the fan acceleration process can be reduced, thereby reducing the power consumption of the power line between the power supply and the parking air conditioner (that is, reducing the voltage drop generated by the power line, the voltage drop is the product of the fan current and the resistance of the power line), saving power of the power supply and extending the normal operation time of the parking air conditioner.

[0048] Step S107: The first proportionality coefficient k corresponding to the target temperature range is 1 The product of the preset normal acceleration is used as the new acceleration, and the fan is controlled to start according to the new acceleration.

[0049] In step S107, since k 1 It is positively correlated with the maximum value of the sub-temperature range and k1 ≤1, therefore, if the maximum value of the target temperature range is large, k 1 is also larger; if the maximum value of the target temperature range is smaller, then k 1 When the maximum value of the target temperature range is large, the required cooling capacity is relatively large, and the use of k 1 The new acceleration is also relatively large, which can enable the fan to start quickly and reduce the temperature inside the car. When the maximum value of the target temperature range is small, the required cooling capacity is relatively small, and the k 1 The new acceleration obtained is also relatively small, which can reduce the fan current generated during the fan acceleration process, thereby saving power of the power supply and extending the normal operation time of the parking air conditioner.

[0050] The following describes a method for controlling the fan start-up when the temperature inside the vehicle does not fall within a preset temperature range.

[0051] In an embodiment of a fan startup control method according to the present invention, if the temperature inside the vehicle is greater than the maximum value of a preset temperature range, indicating that the temperature inside the vehicle is very high and more cooling capacity is required, the preset third proportional coefficient k 3 The product of the preset normal acceleration is used as the new acceleration, and the fan is controlled to start according to the new acceleration. 3 >1.

[0052] If the temperature inside the car is less than the minimum value of the preset temperature range, it indicates that the temperature inside the car is very low and requires little cooling capacity. At this time, it can be determined whether the temperature outside the car is continuously greater than or equal to the preset temperature value within the second time period, wherein the preset temperature value is less than the minimum value of the preset temperature range (for example, the maximum and minimum values ​​of the preset temperature range are 30°C and 16°C respectively, and the preset temperature value can be 10°C). If it is less than or equal to the preset temperature value, it indicates that the temperature outside the car is higher than the temperature inside the car, and the preset fourth proportionality coefficient k can be increased. 4 The product of the preset normal acceleration is used as the new acceleration, and the fan is controlled to start according to the new acceleration. If it is greater than the preset temperature, it indicates that the temperature outside the car is also very low, and the preset fifth proportional coefficient k 5 The product of the preset normal acceleration is used as the new acceleration, and the fan is controlled to start according to the new acceleration; wherein the fourth proportional coefficient k 4 and the fifth proportionality factor k 5 are both less than the first proportionality coefficient k 1 The minimum value of 2 The minimum value of k 5 <k 4 .
