Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive control technology, and in particular to a method for controlling the sterilization and disinfection of a vehicle cabin. Background Technology
[0002] After a vehicle is exposed to the sun outdoors, the temperature inside the car rises sharply, and many harmful gases will evaporate more quickly. In addition, long-term use or parking of a car can also lead to the accumulation of dirt and mold. Since many parts of the interior are in close contact with the human body, they are "hotspots" for bacteria inside the car. Therefore, it is necessary to monitor the microorganisms and air quality inside the car and clean it.
[0003] Currently, most deep ultraviolet seat disinfection devices used in the industry use deep ultraviolet LED lamps (wavelength 200~280nm) to irradiate parts such as seat backs and cushions in a targeted manner, thereby achieving sterilization and disinfection by destroying the DNA / RNA of microorganisms.
[0004] However, after analyzing the existing solutions, it is believed that they have many shortcomings:
[0005] 1. Ultraviolet rays have limited penetrating power and cannot completely sterilize certain areas inside complex air ducts, such as those in vehicle air conditioners.
[0006] 2. Prolonged exposure can cause the equipment structure to become brittle;
[0007] 3. The design does not take into account the vehicle's usage scenarios. If it continues to run, it will increase the power load, resulting in higher vehicle energy consumption. Summary of the Invention
[0008] In view of the above, the present invention aims to provide a method for controlling the sterilization and disinfection of a vehicle cabin to solve the aforementioned technical problems.
[0009] The technical solution adopted in this invention is as follows:
[0010] This invention provides a method for controlling the sterilization and disinfection of a vehicle cabin, comprising:
[0011] Monitor harmful pollutants inside the vehicle cabin;
[0012] By combining the monitoring data with a pre-established pollution target concentration-disinfection intensity model, disinfection information is obtained.
[0013] The disinfection information is sent to the user's mobile terminal;
[0014] After receiving the disinfection information, the user's mobile terminal analyzes the cabin health risk level from the disinfection information and decides whether to activate or deactivate the in-vehicle sterilization system based on different risk levels to execute the preset disinfection mode.
[0015] In at least one possible implementation, the monitored hazardous pollution targets within the vehicle cabin include:
[0016] At least by using microbial sensors and colony imagers placed in preset locations within the vehicle cabin, the concentration and distribution of bacteria inside the vehicle can be monitored.
[0017] In at least one possible implementation, the step of combining the monitoring data with a pre-established pollution target concentration-disinfection intensity model to obtain disinfection information includes:
[0018] The monitoring results are input into a pre-established "bacterial concentration-disinfection intensity" mapping model, and the mapping model outputs disinfection information with at least the risk level and recommended disinfection intensity.
[0019] In at least one possible implementation, the sterilization and disinfection control method further includes: before sending the disinfection information to the user's mobile terminal, dynamically adjusting the risk level in the disinfection information based on at least one of cabin occupant information, vehicle route area, temperature and humidity environment information, and vehicle usage data.
[0020] In at least one possible implementation, sending the disinfection information to the user's mobile terminal includes:
[0021] Establish communication between the vehicle-mounted T-BOX and the user's mobile terminal in advance;
[0022] After obtaining the disinfection information, the disinfection information, including the risk level and disinfection intensity recommendations, is pushed to the user's mobile terminal via T-BOX.
[0023] In at least one possible implementation, the in-vehicle sterilization system includes a combination of the following systems: an air conditioning system, a negative ion air purification system, an ultraviolet disinfection system, and a window system.
[0024] Compared to existing technologies, the main design concept of this invention lies in proposing the concept of a healthy cabin. This involves using an in-vehicle sensing device to continuously or on-demand monitor target pollutants such as microorganisms, air cleanliness, and environmental allergens within the vehicle through preventative maintenance. When a detected target reaches a preset risk threshold, an alert is issued via the user's mobile terminal, triggering disinfection measures and thereby reducing health risks inside the vehicle. Specifically, the invention monitors harmful pollutants within the vehicle cabin; combines the monitoring data with a pre-established pollutant concentration-disinfection intensity model to obtain disinfection information; sends this information to the user; upon receiving the disinfection information, the user's mobile terminal parses the cabin health risk level from the information and decides whether to activate or deactivate the in-vehicle sterilization system based on different risk levels, executing a preset disinfection mode. Furthermore, the mobile terminal allows for setting differentiated disinfection and sterilization trigger conditions for different levels and disinfection areas, significantly reducing unnecessary energy consumption. Attached Figure Description
[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:
[0026] Figure 1 This is a schematic diagram of a vehicle cabin sterilization and disinfection control method provided in an embodiment of the present invention. Detailed Implementation
[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0028] This invention proposes an embodiment of a vehicle cabin sterilization and disinfection control method, specifically, as follows: Figure 1 As shown, it includes:
[0029] Step S1: Monitor harmful pollutant targets inside the vehicle cabin;
[0030] In practice, microbial sensors and colony imagers deployed at predetermined locations within the vehicle cabin can reliably monitor bacterial concentration and colony distribution data. Furthermore, other in-vehicle environmental parameters can also be monitored, but this invention does not limit the scope of the monitoring.
[0031] Step S2: Combine the monitoring data with the pre-established pollution target concentration-disinfection intensity model to obtain disinfection information;
[0032] Specifically, the monitoring results can be input into a pre-established "bacterial concentration-disinfection intensity" mapping model, which will then output a risk level and a disinfection intensity recommendation.
[0033] The mapping model mentioned here can be referenced in the following model table example:
[0034]
[0035] Step S3: Send the disinfection information to the user's mobile terminal;
[0036] Specifically, communication is established in advance between the vehicle-mounted T-BOX and the user's mobile terminal. After receiving the disinfection information, the information can be pushed to the user's mobile terminal via the T-BOX. That is, the cabin contamination risk level represented by the monitoring results and disinfection recommendations are pushed to the user's mobile phone (APP). By linking the user's mobile terminal with the vehicle's infotainment system, the APP can promptly remind the user to disinfect the cabin. Of course, it is understandable that the user can set an automatic disinfection mode or a manual disinfection mode through the APP (that is, allow the user to manually adjust and modify the disinfection strategy as needed).
[0037] Step S4: After receiving the disinfection information, the user's mobile terminal parses the cabin health risk level from the disinfection information and executes the preset disinfection mode based on different risk levels.
[0038] To elaborate further, after receiving a disinfection notification on their mobile phone, users can activate the in-vehicle sterilization system based on preset contamination levels. For example, using the aforementioned model table:
[0039] Level 1 - No active disinfection;
[0040] Level 2—Activate the air conditioning purification / negative ion system;
[0041] Level 3 – Activate low-intensity UV mode (such as skylight light transmission) or intelligent sensing purification system;
[0042] Level 4 – Immediate high-intensity disinfection (ultraviolet light + high temperature combination): The number of lamps, irradiation intensity, and disinfection temperature can be adjusted. It also integrates with the vehicle's air conditioning heating and ventilation functions to accelerate odor dissipation. For example, the air conditioning system circulates air at 65°C for 30 minutes, and combined with the release of negative ions by the plasma generator, a 99.92% sterilization rate can be achieved. If necessary, zoned and targeted sterilization measures can also be adopted (the above disinfection strategies can be modified on the mobile app, such as prioritizing areas with high bacterial density like the steering wheel, gear shift, and seats).
[0043] In addition, the mobile app can also set residual monitoring and ventilation strategies (vehicles can only be unlocked when the residual concentration reaches the standard) and disinfection paths, which are not limited in this invention.
[0044] Finally, it can be added that the present invention also considers combining multi-dimensional monitoring data to implement an enhanced disinfection mechanism. This mainly involves dynamically adjusting the risk level in the disinfection information based on at least one of the following before sending the disinfection information to the user: cabin occupant information, vehicle transit area information, temperature and humidity environmental information, and vehicle usage data.
[0045] 1. If a person with influenza is in the vehicle for a certain period of time, the risk level will be raised even if the bacterial concentration does not reach the risk threshold, and a pre-set virus-specific disinfection program can be activated.
[0046] 2. In high humidity environments (humidity > 70%), fungal growth accelerates, so the risk level should be raised, and an automatic warning system can be used to alert the system.
[0047] 3. In conjunction with the vehicle navigation system, when the system detects that the vehicle is passing through high-risk areas such as hospitals or garbage stations, the risk level should be increased to strengthen disinfection efforts;
[0048] 4. If the vehicle is in a prolonged parking situation, the risk level can be adjusted to the highest level to activate the high-intensity cleaning mode.
[0049] In practice, this embodiment can combine in-vehicle cameras and seat pressure sensors to monitor data such as the number of occupants, their seating positions and durations. It can also access navigation map data query interfaces through the vehicle network platform to determine whether the vehicle has passed through high-risk pollution areas based on its location.
[0050] In summary, the main design concept of this invention is to propose a healthy cabin concept. This involves using an in-vehicle sensing device to continuously or on-demand monitor target pollutants such as microorganisms, air cleanliness, and environmental allergens within the vehicle through preventative maintenance. When a detected target reaches a preset risk threshold, an alert is issued via the user's mobile terminal, triggering disinfection measures and thus reducing health risks inside the vehicle. Specifically, the invention monitors harmful pollutants within the vehicle cabin; combines the monitoring data with a pre-established pollutant concentration-disinfection intensity model to obtain disinfection information; sends this information to the user; upon receiving the disinfection information, the user's mobile terminal parses the cabin health risk level from the information and decides whether to activate or deactivate the in-vehicle sterilization system based on different risk levels, executing a preset disinfection mode. Furthermore, the mobile terminal allows for setting differentiated disinfection and sterilization trigger conditions for different levels and disinfection areas, thereby significantly reducing unnecessary energy consumption.
