Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to an automatic control method, system, medium, and electronic equipment for vehicle ultraviolet germicidal lamps. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the advent of intelligent vehicles, people have increasingly higher demands for driving comfort. In addition, the air quality in urban environments is deteriorating. During the use of car air conditioning, bacteria can easily grow in the air conditioning filter. When the air conditioning is on, the bacteria are blown into the car, making people feel uncomfortable and even affecting their health. The introduction of ultraviolet germicidal lamps for air conditioning has solved this problem.

[0004] However, the inventors discovered that existing control methods require manual operation of button switches, and these switches can be forgotten. If the user does not turn it on, it leads to wasted functionality, and if the user forgets to turn it off, it increases the vehicle's power consumption. Patent number CN111674237A discloses a vehicle ultraviolet disinfection system and a method for disinfecting a vehicle using this system. Before turning on the ultraviolet disinfection device, it determines whether to turn on the vehicle's air conditioning based on the vehicle's interior temperature provided by an in-vehicle temperature sensor, and turns on the vehicle's air conditioning after the ultraviolet disinfection device is turned off. It requires turning off the ultraviolet disinfection device after turning on the air conditioning. Although it achieves automatic control of the vehicle-mounted ultraviolet disinfection device, it cannot achieve stable operation of the ultraviolet disinfection device when the air conditioning is on, and therefore cannot achieve effective sterilization. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic control method, system, medium, and electronic device for vehicle ultraviolet (UV) germicidal lamps. When the vehicle's air conditioning is turned on, the UV germicidal lamp is activated. After a first set time, the UV germicidal lamp is turned off. After a second set time, the UV germicidal lamp is activated again; this cycle repeats until the vehicle's air conditioning is turned off. When the vehicle's air conditioning is turned off, the UV germicidal lamp is activated for the first set time and then turned off. This method fully and efficiently utilizes the UV germicidal lamp's function, improving the sterilization effect while ensuring its safe operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0020] As a further limitation of the second aspect of the present invention, in the switch control module, when the ultraviolet lamp is turned on, it enters the ultraviolet lamp automatic mode; when the vehicle air conditioner is not turned on, the ultraviolet germicidal lamp is turned on for a first set time and then turned off.

[0021] When the vehicle's air conditioning is turned on, the ultraviolet germicidal lamp turns on. After a first set time, the ultraviolet germicidal lamp turns off.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0041] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0042] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0043] Example 1:

[0044] like Figure 1 As shown, Embodiment 1 of the present invention provides an automatic control method for a vehicle ultraviolet germicidal lamp, wherein the ultraviolet germicidal lamp is located between the air filter and the blower (e.g., Figure 2 As shown), it includes the following processes:

[0045] The intensity of the ultraviolet germicidal lamp, the first set time for turning it on, and the second set time for turning it off are determined based on the real-time temperature of the evaporator.

[0046] When the vehicle air conditioner is turned on, the ultraviolet germicidal lamp turns on. After a first set time, the ultraviolet germicidal lamp turns off. After a second set time, the ultraviolet germicidal lamp turns on again. This cycle repeats until the vehicle air conditioner is turned off. When the vehicle air conditioner is turned off, the ultraviolet germicidal lamp turns on for the first set time and then turns off.

[0047] More specifically, when passengers turn on the air conditioning, the ultraviolet germicidal lamp activates its automatic mode and begins timing. The intensity and duration of the ultraviolet germicidal lamp are determined by referring to a table based on the evaporator temperature (a low evaporator temperature will lead to more bacterial growth if not dried promptly, so sterilization is performed before the air enters the evaporator). After the preset duration T1 seconds, the ultraviolet germicidal lamp is turned off, and the timing restarts. After the off duration T2 seconds, it is turned on again, and this cycle repeats continuously. When the air conditioning is off, the ultraviolet germicidal lamp is turned on for T1 seconds and then turned off, without repeating the cycle.

[0048] In this embodiment, preferably, the first set time decreases as the real-time temperature of the evaporator increases, and the second set time increases as the real-time temperature of the evaporator increases. The sterilization intensity, the first set time, and the second set time are shown in Table 1.

[0049] Table 1: Relationship between sterilization intensity, first set time, second set time, and evaporator surface temperature

[0050]

[0051] In this embodiment, preferably, the UV lamp enters the automatic UV lamp mode when the UV lamp is turned on, and turns off after the UV germicidal lamp is turned on for a first set time when the vehicle air conditioner is not turned on.

[0052] When the vehicle's air conditioning is turned on, the ultraviolet germicidal lamp turns on. After a first set time, the ultraviolet germicidal lamp turns off. After a second set time, the ultraviolet germicidal lamp turns on again. This cycle repeats until the vehicle's air conditioning is turned off.

[0053] In this embodiment, preferably, when the ultraviolet lamp is not turned on and the air conditioner is not turned on, the ultraviolet lamp remains off; when the air conditioner is turned on, the ultraviolet germicidal lamp is turned on.

[0054] After the first set time is activated, the ultraviolet germicidal lamp turns off. After the second set time is activated, the ultraviolet germicidal lamp turns on again. This cycle repeats until the vehicle's air conditioning is turned off.

[0055] Example 2:

[0056] Embodiment 2 of the present invention provides an automatic control system for vehicle ultraviolet germicidal lamps, such as... Figure 3 As shown, the ultraviolet germicidal lamp is located between the air filter and the blower, and includes the following process:

[0057] The parameter determination module is configured to: determine the UV germicidal lamp's activation intensity, the first preset activation time, and the second preset deactivation time based on the evaporator's real-time temperature.

[0058] The switch control module is configured to: when the vehicle air conditioner is turned on, the ultraviolet germicidal lamp turns on; after a first set time, the ultraviolet germicidal lamp turns off; after a second set time, the ultraviolet germicidal lamp turns on again; this cycle repeats until the vehicle air conditioner is turned off; when the vehicle air conditioner is turned off, the ultraviolet germicidal lamp turns on for a first set time and then turns off.

[0059] In this embodiment, preferably, the first set time decreases as the real-time temperature of the evaporator increases, and the second set time increases as the real-time temperature of the evaporator increases. The sterilization intensity, the first set time, and the second set time are shown in Table 2.

[0060] Table 2: Relationship between sterilization intensity, first set time, second set time, and evaporator surface temperature

[0061]

[0062] In the switch control module, when the ultraviolet lamp is turned on, it enters the automatic ultraviolet lamp mode; when the vehicle air conditioner is not turned on, the ultraviolet germicidal lamp turns on for a first set time and then turns off.

[0063] When the vehicle's air conditioning is turned on, the ultraviolet germicidal lamp turns on. After a first set time, the ultraviolet germicidal lamp turns off. After a second set time, the ultraviolet germicidal lamp turns on again. This cycle repeats until the vehicle's air conditioning is turned off.

[0064] In the switch control module, the ultraviolet lamp remains off when it is not turned on and the air conditioner is not turned on; when the air conditioner is turned on, the ultraviolet germicidal lamp is turned on.

[0065] After the first set time is activated, the ultraviolet germicidal lamp turns off. After the second set time is activated, the ultraviolet germicidal lamp turns on again. This cycle repeats until the vehicle's air conditioning is turned off.

[0066] Example 3:

[0067] like Figure 4 As shown, Embodiment 3 of the present invention provides an automatic control system for a vehicle ultraviolet germicidal lamp, comprising:

[0068] The system includes an air conditioning controller, a large in-vehicle infotainment screen, an evaporator temperature sensor, and an ultraviolet germicidal lamp located between the air filter and the blower. The large in-vehicle infotainment screen is used to display the intensity and status of the ultraviolet lamp.

[0069] The air conditioning controller is connected to the vehicle's large screen and the ultraviolet germicidal lamp via CAN bus. The air conditioning controller obtains the measured temperature of the evaporator temperature sensor through AD sampling.

[0070] The air conditioning controller receives the air conditioning turn-on command sent by the vehicle's infotainment screen via the CAN bus, and feeds back the intensity and on / off status of the ultraviolet lamp to the vehicle's infotainment screen via the CAN bus for display.

[0071] The air conditioning controller is used to execute the steps of the automatic control method for vehicle ultraviolet germicidal lamps described in Embodiment 1 of the present invention. The air conditioning controller sends lamp intensity and switch signals to the ultraviolet germicidal lamp through the CAN bus, and receives the lamp intensity and switch status feedback from the ultraviolet germicidal lamp.
