Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle air conditioning control system and a method for starting the vehicle air conditioning system. Background Technology

[0002] With the development of technology, existing vehicles are usually equipped with air conditioners to provide users with a better driving environment. However, for large vehicles, such as trucks, although the original air conditioners have a large and rapid heat exchange capacity, they will significantly increase the vehicle's fuel consumption. This means that truck drivers will have to refuel more frequently, which will not only delay the normal transportation of the truck, but also increase costs. In addition, the original air conditioners cannot control the compressor speed through belt drive, so the driver can only control the heat exchange by adjusting the air volume. When the heat exchange is large, the noise is usually also large.

[0003] To address these issues, users typically install parking air conditioners on large vehicles. Parking air conditioners offer advantages such as fuel efficiency, quiet operation, and variable frequency control, and can be powered by the vehicle battery. However, driving environments are often variable, requiring users to manually select between the original vehicle air conditioner and the parking air conditioner. This not only fails to guarantee an optimal driving environment at all times but also diminishes the user experience. Summary of the Invention

[0040] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.

[0041] Figure 1 This is a control logic flowchart of an embodiment of the vehicle air conditioning system start-up method of the present invention.

[0042] Figure 2 This is a detailed control flowchart of an embodiment of the vehicle air conditioning system start-up method of the present invention. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0044] Currently, in existing vehicles, users need to manually select between the original vehicle air conditioning and the parking air conditioning based on the driving environment. This not only fails to guarantee an optimal driving environment but also reduces the user experience. In this embodiment of the invention, a first and second detection module acquires the interior and exterior temperatures of the vehicle's cabin when the air conditioning is turned on, and a third detection module detects the number of occupants inside the cabin. A data processing module then determines the vehicle's current status based on the acquired interior and exterior temperatures and the number of occupants, rationally selecting to activate the parking air conditioning and / or the original vehicle air conditioning. This saves energy and improves user comfort when using the air conditioning.

[0045] The following is in conjunction with the appendix Figure 1-2 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0046] Example

[0047] On the one hand, this embodiment proposes a vehicle air conditioning control system, which includes the original vehicle air conditioning and the parking air conditioning. The vehicle air conditioning control system includes:

[0048] The first detection module is used to detect the internal temperature T1 of the vehicle's cab.

[0049] The second detection module is used to detect the external temperature T2 of the vehicle cab.

[0050] The third detection module is used to detect the number N of people inside the vehicle's driver's cab.

[0051] The control module controls the operation of the original vehicle air conditioner and the parking air conditioner based on the temperature difference △T between the driver's cab and the outside temperature and the number of people N inside the driver's cab.

[0052] In this embodiment of the invention, by setting a first detection module and a second detection module, the internal temperature T1 and external temperature T2 of the vehicle's driver's cab can be obtained when the air conditioner is turned on. By setting a third detection module, the number of people N inside the driver's cab can be detected. The control module can reasonably control the turning on of the parking air conditioner and the original vehicle air conditioner based on the difference ΔT between the internal and external temperatures and the number of people N inside the driver's cab, thereby saving energy and improving the user's comfort when using the air conditioner.

[0053] It is worth noting that obtaining the temperature difference ΔT between the inside and outside of the vehicle's cab and obtaining the number of people N inside the cab are not in any particular order.

[0054] In the above technical solution, controlling the operation of the original vehicle air conditioner and the parking air conditioner based on the temperature difference ΔT between the driver's cab and the outside and the number of people N inside the driver's cab includes:

[0055] The temperature difference ΔT is compared with the preset temperature difference threshold ΔT1 and the preset temperature difference threshold range [ΔTmin, ΔTmax] to obtain the first comparison result, where ΔTmin is the first preset temperature difference threshold, ΔT1 is the second preset temperature difference threshold, and ΔTmax is the third preset temperature difference threshold, and ΔTmin < ΔT1 ≤ ΔTmax.

[0056] The number of internal personnel N is compared with the preset personnel number range [Nmi n, Nmax] to obtain a second comparison result, where Nmi n is the first preset personnel number, Nmax is the second preset personnel number, and Nmi n < Nmax;

[0057] Based on the first comparison result and the second comparison result, control the original vehicle air conditioner and / or the parking air conditioner to start and operate.

[0058] In any of the above embodiments, the absolute value of the difference between the internal temperature T1 and the external temperature T2 of the cab is taken as the internal and external temperature difference ΔT. This facilitates the comparison of ΔT with ΔTmin and ΔTmax.

[0059] In any of the above embodiments, controlling the original vehicle air conditioner and / or the parking air conditioner to start operation based on the first comparison result and the second comparison result includes:

[0060] When △Tmi n<△T≤△T1 and Nmi n≤N<Nmax, the vehicle's original air conditioning is turned on, while the parking air conditioning remains off. For example, if there are 3 people in the car at this time, the number of people is not large, and the impact on the temperature inside the driver's cab is small. At this time, the temperature difference is 0<△T≤△T1. The temperature difference between the inside and outside of the driver's cab is not large. Turning on the original air conditioning can quickly adjust the temperature to the user's required temperature without turning on the parking air conditioning, thus avoiding waste of resources.

[0061] When △Tmi n<△T≤△T1 and N=Nmax, the vehicle parking air conditioner is turned on to keep the original air conditioner off. For example, if there are 5 people in the driver's cab, the temperature of the people themselves and the carbon dioxide they exhale have a significant impact on the temperature inside the cab. However, the temperature difference is 0<△T≤△T1, and the temperature difference between the inside and outside of the cab is not large. Therefore, turning on the parking air conditioner can quickly adjust the room temperature without turning on the original air conditioner, which is fast, efficient, and saves resources.

[0062] When △T1<△T≤△Tmax and Nmi n≤N<Nmax, the vehicle parking air conditioner is turned on to keep the original air conditioner off. For example, if there are 3 people in the car at this time, although the number of people in the driver's cab is not large, the temperature difference in the driver's cab is large. Therefore, turning on the parking air conditioner can quickly adjust the room temperature without turning on the original air conditioner, which is fast, efficient and saves resources.

[0063] When △T1<△T≤△Tmax and N=Nmax, the parking air conditioner and the original vehicle air conditioner are turned on and running simultaneously. For example, if there are 5 people in the vehicle at this time, and the temperature difference △T1<△T≤△T1's upper limit, the number of people has a significant impact on the temperature inside the driver's cab, and the temperature difference between the inside and outside of the driver's cab is also large. Therefore, it is necessary to turn on the parking air conditioner and the original vehicle air conditioner together to quickly adjust the indoor temperature and improve user comfort.

[0064] In summary, by determining the current state of the vehicle, this embodiment of the invention can rationally select to turn on the parking air conditioner and / or the original vehicle air conditioner, thereby saving resources and improving user comfort.

[0065] In the above technical solution, △Tmi n takes the value of 0, △Tmax takes the value of 44, Nmi n takes the value of 1, and Nmax takes the value of 5.

[0066] In any of the above embodiments, the parking air conditioner mentioned above includes an indoor unit located inside the driver's cab and an outdoor unit located outside the driver's cab.

[0067] The first detection module is located on the indoor unit, and the second detection module is located on the outdoor unit; the first detection module and the second detection module include temperature sensors located on the indoor unit and the outdoor unit, respectively.

[0068] In any of the above embodiments, the third detection module includes one or a combination of an infrared detection device, a millimeter-wave radar device, and a scanning camera. Of course, the specific form of the third detection module is not limited to the above forms. In some alternative embodiments, the third detection module can adopt any detection equipment that can directly detect personnel.

[0069] In any of the above embodiments, both the original vehicle air conditioner and the parking air conditioner mentioned above include an air conditioner capable of heat exchange, and both can perform functions such as cooling, heating, and ventilation of the air in the vehicle's driver's compartment.

[0070] On the other hand, this embodiment of the invention also provides a method for starting a vehicle air conditioning system, applied to the aforementioned vehicle air conditioning control system, the starting method comprising:

[0071] When the vehicle receives the air conditioning start signal, it obtains the temperature difference ΔT between the driver's cabin and the outside temperature and the number of people N inside the driver's cabin.

[0072] The original vehicle air conditioner and the parking air conditioner are controlled to operate based on the actual temperature difference △T between the driver's cab and the outside temperature and the number of people N inside the driver's cab.

[0073] In this embodiment of the invention, when the vehicle is started, the original vehicle air conditioner and the parking air conditioner can be turned on reasonably according to the actual temperature difference ΔT between the driver's cab and the outside and the number of people N inside the driver's cab. This allows the vehicle to quickly, comfortably, and energy-efficiently adjust the temperature inside the vehicle to the temperature range desired by the user, thereby improving user satisfaction.

[0074] It is worth noting that, in this embodiment of the invention, the temperature difference ΔT between the driver's cab and the outside, and the number of occupants N inside the driver's cab, can be acquired either during vehicle operation or immediately after the vehicle is started. Relatively speaking, acquiring the temperature difference ΔT between the driver's cab and the outside, and the number of occupants N, immediately after the vehicle is started allows for a faster, more comfortable, and energy-efficient adjustment of the vehicle's interior temperature to the user's desired range, thus improving user satisfaction.

[0075] In any of the above embodiments, the method for controlling the operation of the original vehicle air conditioner and the parking air conditioner based on the actual temperature difference ΔT between the driver's cab and the outside and the number of people N inside the driver's cab includes:

[0076] The temperature difference ΔT is compared with the preset temperature difference threshold ΔT1 and the preset temperature difference threshold range [ΔTmin, ΔTmax] to obtain the first comparison result, where ΔTmin is the first preset temperature difference threshold, ΔT1 is the second preset temperature difference threshold, and ΔTmax is the third preset temperature difference threshold, and ΔTmin < ΔT1 ≤ ΔTmax.

[0077] The number of internal personnel N is compared with the preset personnel number range [Nmi n, Nmax] to obtain a second comparison result, where Nmi n is the first preset personnel number, Nmax is the second preset personnel number, and Nmi n < Nmax;

[0078] Based on the first comparison result and the second comparison result, control the original vehicle air conditioner and / or parking air conditioner to be turned on and operated.

[0079] In any of the above embodiments, the method for controlling the original vehicle air conditioner and / or the parking air conditioner to start operation based on the first comparison result and the second comparison result includes:

[0080] When △Tmi n<△T≤△T1 and Nmi n≤N<Nmax, control the original vehicle air conditioner to turn on and keep the parking air conditioner off.

[0081] When △Tmi n<△T≤△T1, N=Nmax, control the vehicle parking air conditioner to turn on and keep the original vehicle air conditioner off;

[0082] When △T1<△T≤△Tmax and Nmi n≤N<Nmax, control the vehicle parking air conditioner to turn on and keep the original vehicle air conditioner off.

[0083] When △T1<△T≤△Tmax and N=Nmax, the parking air conditioner and the original vehicle air conditioner are turned on and running simultaneously.

[0084] In any of the above embodiments, preferably, △Tmi n is 0, △Tmax is 44, Nmi n is 1, and Nmax is 5.

[0085] In any of the above embodiments, preferably, the values ​​of △Tmi n, △Tmax, Nmi n and Nmax mentioned above are not limited to these. In some alternative embodiments, the values ​​of △Tmi n, △Tmax, Nmi n and Nmax can also be changed. Specifically, they can be set according to the vehicle specifications.

[0086] In any of the above embodiments, the vehicle may have the following characteristics:

[0087] Case 1: When the judgment result is △Tmi n<△T≤△T1, Nmi n≤N<Nmax;

[0088] Scenario 2: When the judgment result is △Tmi n<△T≤△T1, N=Nmax;

[0089] Scenario 3: When the judgment result is △T1<△T≤△Tmax, Nmi n≤N<Nmax;

[0090] Scenario 4: When the judgment result is △T1<△T≤△Tmax, N=Nmax;

[0091] In scenarios one, two, three, and four, the actual temperature difference ΔT is detected in real time. When the actual temperature difference ΔT reaches the preset temperature difference or preset temperature difference range (different vehicles can set different temperature difference values ​​or temperature difference ranges, which are the temperature ranges that are relatively comfortable for the human body), the parking air conditioner and / or the original vehicle air conditioner are controlled to switch from cooling or heating mode to the vehicle's internal circulation mode. This avoids the parking air conditioner and the original vehicle air conditioner from being in cooling or heating mode for a long time, saving battery power and vehicle fuel consumption.

This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
